Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.2.0
Disambiguation2/5
Many tools overlap in purpose, such as multiple LSB detection tools (img_lsb_detect, img_chi_square, img_rs_analysis) and numerous JPEG analysis tools, making it difficult for an agent to distinguish between them. While some tools have distinct focuses, the sheer number and similarity of detection tools cause significant ambiguity.
Naming Consistency4/5
Tool names follow a mostly consistent pattern: format prefix plus action (e.g., audio_lsb_detect, video_frame_extract). However, there are deviations like 'create_whitespace' without a format prefix and the 'jpegadv_' prefix for advanced JPEG tools, which slightly breaks the pattern. Overall, naming is clear and predictable.
Tool Count1/5
128 tools is extremely high for a single MCP server, far exceeding typical scopes (3-15 tools). This overwhelms the agent's selection process and suggests the server should be split into multiple smaller, focused servers (e.g., image-stego, audio-stego, network-stego).
Completeness4/5
The toolset covers an impressively broad range of steganographic techniques across many file formats (images, audio, video, text, network, etc.), including detection, extraction, and embedding. Minor gaps exist (e.g., no MP4 video support), but overall the coverage is thorough and leaves few workflow dead-ends.
Average 3.7/5 across 128 of 128 tools scored. Lowest: 2.9/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description does not disclose important behavioral details such as the missing 'n' parameter for nth_word mode, nor does it state the tool is non-destructive or has no side effects. Since no annotations are provided, the description carries the full burden but falls short.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (three sentences, ~60 words), front-loaded with the purpose, and efficiently explains the two modes and output. Every sentence earns its place with no fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description fails to mention that nth_word mode requires an additional 'n' parameter, which is absent from the input schema. This omission makes the tool specification incomplete and potentially confusing. No output schema is provided, but description adequately states return value.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description repeats information already in the schema's parameter descriptions (e.g., modes explained in both places). It adds no new semantic value about the parameters themselves.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool creates a null cipher text hiding a secret message via letter selection, and distinguishes two modes. However, it does not explicitly differentiate from sibling creation tools like text_acrostic, and the missing 'n' parameter for nth_word mode slightly undermines clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives (e.g., text_acrostic or other text steganography creation tools). The description only explains functionality without suggesting appropriate scenarios or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavior. It explains the detection method but omits critical details: what the output looks like (e.g., boolean, confidence score), whether the tool is purely read-only, and any side effects or requirements (e.g., decompression overhead). The agent is left unsure how to interpret results.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at two sentences, no wasted words. It front-loads the core purpose and then adds technical detail. Slightly technical language may be less accessible, but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has a single parameter and no output schema, the description should elaborate on return values or how to interpret detection results. The agent lacks information on success/failure conditions, output format, or false positive considerations, making it incomplete for effective invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a clear description of file_path. The tool description adds little beyond restating 'JPEG file to analyze,' which is already in the schema. Baseline score of 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool detects PVD steganography in JPEG files, specifying the method (analyzing pixel difference distributions for staircase patterns) and that it works on decoded pixel data via jpeg-js. It is specific and distinguishable from siblings by its focus on PVD, though it does not explicitly contrast with other jpegadv detect tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives (e.g., jpegadv_f5_detect, jpegadv_jsteg_detect). It does not mention prerequisites, limitations, or contexts where PVD detection is appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It lists detection categories but fails to disclose behavioral traits (e.g., read-only, output format, performance implications).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Concise single sentence plus bullet list of detection techniques. Front-loaded with purpose, but could be tightened further.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, description should explain return values (e.g., report, found items). It only lists what is scanned, leaving the agent uninformed about results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with one parameter (file_path) described. Tool description adds no additional meaning or format details beyond the schema, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Hidden HTML content detection' and enumerates specific types (HTML comments, display:none, etc.), distinguishing it from sibling tools like text_invisible_scan or doc_pdf_hidden which target other formats.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool vs alternatives. It does not mention prerequisites, when not to use, or refer to sibling tools for other file types.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It mentions outputs but does not state whether the tool modifies the image, requires permissions, or has side effects. As a likely read-only tool, this omission is a notable gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two clear sentences, front-loaded with the main action, no wasted words. An example of effective conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so the description must convey return values. It mentions dimensions, percentage, and ASCII preview, which covers the main outputs, but it is unclear whether the extracted bit plane image data is also returned. Adequate but not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds general context about extraction and visualization but does not provide extra meaning beyond what the schema's parameter descriptions already offer.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it extracts and visualizes a specific bit plane from an image channel, and lists what it shows (dimensions, percentage, ASCII preview). However, it does not distinguish itself from sibling tools like img_lsb_extract which also deal with bit planes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. The description implies use for bit plane analysis but provides no context on prerequisites or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavior. It states it examines patterns and entropy to detect hidden data, but does not clarify if it modifies data, what output format to expect, or any prerequisites beyond file_path. Lacks detail on side effects or read-only nature.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences that front-load the purpose. No superfluous words. Could be slightly improved by combining information, but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (analyzing multiple IP fields for covert data) and lack of output schema, the description should clarify what results are produced (e.g., flagged packets, entropy values). Current description leaves the agent guessing about output, making it incomplete for informed selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a single parameter file_path described as 'Path to PCAP capture file'. The description adds no further meaning to the parameter beyond the schema, so baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Describes specific verb-examines TTL patterns, IP ID entropy, TOS/DSCP to detect hidden data in IP header fields. Distinguishes from sibling tools like net_tcp_header and net_icmp_payload which focus on different layers. However, 'examines' is somewhat passive; a more active verb like 'analyzes' would be clearer.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage when covert data is suspected in IP header fields, but does not explicitly state when to use this tool vs alternatives like net_tcp_header or net_dns_tunnel. No exclusions or contextual clues provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It states the tool computes autocorrelation but does not confirm that it is read-only, nor does it describe output format, error handling, or limitations. The agent has little information about side effects or requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, concise and front-loaded with the core purpose. It avoids extraneous information, earning a high score for efficient communication.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Without an output schema, the description should clarify what the tool returns, but it does not. It also lacks prerequisites, file size limits, or error conditions. For a detection tool, this gap in completeness is significant.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for all three parameters. The description does not add significant detail beyond the schema, so it meets the baseline expectation but does not enhance parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it computes autocorrelation of pixel values to find periodic embedding patterns, with a clear verb and resource. It distinguishes from siblings like spread_dft_analysis by focusing on autocorrelation, but could be more explicit about when to use this specific method.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for detecting spread spectrum and watermarking methods, but offers no explicit when-to-use or when-not-to-use guidance. No alternatives are mentioned, leaving the agent to infer from context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It mentions entropy calculation and classification but does not disclose behavioral traits such as performance characteristics, edge case handling, or any limitations beyond basic functionality.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences that efficiently convey the core purpose and additional detail. No unnecessary words; front-loaded with the main action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description should ideally describe return values. It mentions classification categories but not the structure of results. For a simple tool with one parameter, it is adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (one parameter with description 'String to analyze'). The description adds value by explaining the output classification categories, which goes beyond the schema. However, it could still be more explicit about expected input formats.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it calculates Shannon entropy for strings, specifying both character and byte levels and classification. While clear, it doesn't explicitly differentiate from similar sibling tools like file_entropy or img_entropy_map, which may operate on different data types.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like crypto_frequency or file_entropy. The description merely states what it does without context for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full weight for behavioral disclosure. It describes the extraction process (collecting LSBs from each byte, assembling into a stream) and output format (hex dump, text preview). However, it omits details like error handling (e.g., out-of-bounds frames), performance implications, whether the file is modified (likely no), or any required codec support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise (two sentences), front-loaded with the main action, and includes essential details about the output. Every sentence adds value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
There is no output schema, so the description should compensate by explaining the return structure. It mentions 'byte stream with hex dump and text preview' but does not specify how these are presented (e.g., JSON object keys, data types). This leaves the agent without clear guidance on consuming the tool's output. Given moderate tool complexity, more detail is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description mentions 'specified frames' but does not add new semantics beyond the schema's parameter descriptions (e.g., format of 'frames' as comma-separated, defaults). It does explain how parameters are used in the overall process, but that aligns with the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Extract LSB data from video frames as bytes') and the resource ('video frames'), with a specific technique (LSB). It explains the process and output (byte stream with hex dump and text preview). However, it does not distinguish from the sibling tool 'video_frame_lsb', which might be a detection variant, so not a perfect 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus alternatives like 'video_frame_lsb' or 'video_detect'. There are no prerequisites, exclusions, or usage contexts mentioned. The description is purely functional.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It only lists what is reported but does not mention whether the file is read-only, permissions required, or any side effects. This is insufficient for a tool that processes files.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise (two sentences) and front-loaded with the core purpose. Every word adds value, listing specific outputs without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the description lists key metadata, it lacks details about the output format or what 'file structure overview' includes. Given the complexity of MP3 metadata and absence of output schema, more context would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and the description does not add meaning beyond 'file_path: Path to MP3 audio file'. The description focuses on output rather than parameter details, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Full MP3 metadata extraction' and lists specific metadata types (ID3v1 tag, ID3v2 frames, duration, bitrate, VBR status, sample rate, file structure overview), distinguishing it from sibling tools like mp3_detect or mp3_frame_analysis which focus on detection or frame-level details.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. With many related sibling tools (e.g., mp3_id3_hidden, mp3_padding, mp3_structure), the absence of context or exclusions leaves the agent without decision support.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description must disclose behavior. It states the tool 'computes' and 'detects,' implying read-only analysis, but does not explicitly confirm it does not modify the file or mention any prerequisites.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with no wasted words. The first sentence states the core purpose; the second provides detail on what is computed and why.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool with no output schema, the description covers what it does but does not hint at the return format or whether results are displayed or saved. It is adequate but not comprehensive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single parameter with a basic description. The tool description adds context about analyzing decoded frame sizes but does not improve parameter understanding beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs statistical analysis of decoded MP3 frame sizes and lists specific computations (entropy, variance, anomalies) to detect steganography. It distinguishes from siblings like mp3_frame_analysis which likely focuses on frame structure rather than statistical distribution.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. It implies use for steganography detection but does not mention when not to use or compare to related tools like mp3_detect or audio_detect.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It explains the chi-square method and grouping by value pairs, but does not disclose the output format (e.g., p-value, boolean), error conditions, or limitations (e.g., only works on uncompressed WAV). Partial transparency leaves gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences: the first states the tool's function, the second details the method. It is concise and front-loaded, but could be slightly tighter (e.g., combining sentences). No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a single-parameter detection tool with no output schema, the description explains the method but omits the output format (e.g., returns a chi-square statistic or detection verdict). This leaves the agent uncertain about how to interpret results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single parameter (file_path), documented as 'Path to WAV file'. The description adds no additional semantics beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description specifies the tool's function: PCM sample LSB statistical analysis using a chi-square test to detect LSB replacement steganography in WAV audio. It clearly distinguishes from sibling tools like audio_lsb_extract (extraction) and audio_echo_detect (different technique).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives (e.g., audio_detect, img_chi_square) or when not to use it. The description only states what it detects, but lacks context for selection among many sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden of behavioral disclosure. It explains that the tool computes border complexity and produces a spatial map, but it does not specify the output format, whether the tool modifies files, or any required permissions. The information is adequate but not exhaustive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and front-loaded with the core purpose. Two sentences efficiently convey the tool's action and methodology without extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool lacks an output schema, and the description does not clarify the output format (e.g., image, data structure). For a tool that produces a 'spatial map,' more details on return type or visualization are needed for completeness. Additionally, given sibling tools, more differentiation would be helpful.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for all three parameters (channel, file_path, threshold). The description adds minimal value beyond the schema, mentioning 'for a given channel' but not providing additional context on usage or syntax. Baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: generating a detailed complexity map of all bit planes for a given channel. It specifies the method (border complexity for 8x8 blocks across all 8 bit planes) and the output (spatial map showing complex regions). This effectively distinguishes it from sibling tools like bpcs_detect or bpcs_extract.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or other tools' use cases. This leaves the agent without context for choosing between complexity_map and related tools like bpcs_capacity or bpcs_threshold.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavior. It explains the analysis process (testing thresholds, analyzing ratio changes) but does not state that the tool is read-only (no modifications to files) or any potential side effects. Additional context like required permissions or performance impact is missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, concise and front-loaded with the core purpose. It avoids unnecessary words. However, it could be slightly more compact by integrating the second and third sentences, but it remains efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and the tool's analytical nature, the description provides an overview of what it does but lacks detail on the output format (e.g., what kind of data is returned). It mentions identifying suspicious ratios but not how they are presented. The tool's complexity warrants a bit more detail on outputs.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, meaning each parameter is described in the schema. The description adds general context about the tool's purpose but does not elaborate on the specific parameters (plane, channel, file_path) beyond what the schema provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: complexity threshold analysis for BPCS steganalysis. It uses specific verbs like 'tests', 'analyzes', 'finds', and 'identifies', and distinguishes from sibling bpcs tools by focusing on threshold boundary and suspicious ratios.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is used for threshold analysis to find detectability boundaries, but it does not explicitly state when to use it versus other bpcs tools (e.g., bpcs_detect, bpcs_complexity_map) or provide when-not-to-use guidance. No alternatives are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description explains the detection mechanism with format-specific markers, which is transparent. But with no annotations, it omits details about output, side effects, or limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three concise sentences front-load the purpose, list supported formats, and mention common usage. No unnecessary information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description covers the tool's function and detection scope adequately but lacks details on return values and error handling.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter file_path is fully described in the schema (100% coverage). The description adds no extra semantics beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool detects data appended after file-specific EOF markers, lists supported formats and common use. However, it does not differentiate from siblings like img_appended_data or file_embedded.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for PNG, JPEG, BMP, ZIP, and PDF files when suspecting hidden data, but does not provide explicit guidance on when to use this tool over alternatives or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It only states 'Analyze' and 'Inspects,' implying a read-only operation, but does not explicitly confirm non-destructiveness, permission requirements, or any side effects. The description is insufficient to fully inform an agent about the tool's behavior, such as whether it modifies the file or requires specific access.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with two sentences, no fluff, and front-loads the core purpose. Every sentence is meaningful and directly related to the tool's function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and the specific domain (GIF steganography), the description is incomplete. It does not describe the output format or what anomalies or hidden data payloads might look like. For a tool with a single parameter and no schema to describe returns, the description should provide more context on what the agent can expect after invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with one required parameter 'file_path' described as 'Path to GIF image file.' The description adds no extra semantics beyond the schema, such as path format, size limits, or file type restrictions. Baseline of 3 is appropriate since the schema already covers the parameter, but the description provides minimal additional value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool analyzes GIF application extensions, specifically NETSCAPE and other blocks, for anomalies or hidden data. The verb 'Analyze' and 'Inspects' combined with the specific resource 'GIF application extensions' makes the purpose precise and distinguishable from sibling tools like gif_comment (which analyzes comments) or gif_structure (which analyzes overall structure).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for analyzing application extensions but does not explicitly state when to use this tool over siblings like gif_comment or gif_palette. It lacks when-not-to-use clauses or alternatives, providing only implicit guidance. For a tool with many siblings, more explicit differentiation would improve the score.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description does not disclose behavioral traits beyond its function (e.g., read-only nature, permissions, side effects). It only states what it reports, not how it operates.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise, front-loaded sentences with no redundant information. The first sentence states the action, the second lists outputs.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description adequately summarizes the output format and content. It clarifies the scope (GIF color table entries), which is useful among many steganalysis tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only one parameter (file_path) with 100% schema description coverage. The description adds no extra semantics beyond the schema, so baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool extracts and analyzes LSB patterns from GIF color table entries, listing specific outputs (per-channel bit strings, balance ratios, chi-square test results). This distinguishes it from siblings like gif_palette or img_lsb_detect.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives (e.g., img_lsb_detect for generic images). The description doesn't mention prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations, so description must cover behavior. Discloses use of two statistical analyses per color channel independently, but fails to state whether the tool is read-only or what side effects exist. Moderate disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, efficient and front-loaded with core purpose. No extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Lacks output description. For a detection tool, it is crucial to describe what result is returned (e.g., probability scores, detection flags). No output schema exists, so the description should compensate. Incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers file_path with a basic description. The tool description does not add any additional meaning about the parameter, such as supported file formats or path requirements. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description explains the internal detection method (second-order statistics, histogram preservation), which provides some behavioral insight. However, it does not state external behaviors like whether the tool is read-only, or what it returns (e.g., boolean, confidence). With no annotations provided, the description should have covered these aspects more thoroughly.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise: two sentences, no wasted words. The first sentence states the purpose, the second adds technical context. It is front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (steg detection), the description omits critical information about return values or output format. Without an output schema, the agent cannot know what to expect from the tool, making it incomplete for practical use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries the burden of behavioral disclosure. It explains what the tool analyzes (gaps, inter-frame data) but does not specify if the tool modifies files, requires permissions, or has side effects. It also omits behavior for invalid files or edge cases.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?

Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers input and analysis actions but omits output details (format of report, boolean vs. detailed). Since no output schema exists, the description should describe the return value for completeness. Missing this context reduces completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only one parameter (file_path) with schema description 'Path to GIF image file'. The tool description adds 'GIF file' context but no additional semantics beyond the schema. Schema coverage is 100%, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states auto-detection of steganography in GIF files, listing specific techniques (LSB, appended data, comment extensions) and reports (frame count, animation info). Distinguishes from sibling tools like gif_frame_analysis or gif_palette_lsb.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. Does not mention when not to use it or suggest specialized tools for specific stego types, leaving the agent to infer from the description alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must fully disclose behavior. It lists reported properties but does not state whether the tool is read-only, requires permissions, or has side effects. The analytical nature is implied but not confirmed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two succinct sentences, front-loaded with purpose and followed by specific attributes. No redundant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With one parameter and no output schema, the description covers core functionality but lacks details on error scenarios, file constraints, or return format. Adequate but not comprehensive.

Implied usage for multi-frame GIF animation analysis, but no explicit guidance on when not to use (e.g., static GIFs) or how it differs from other GIF tools among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses that it checks for hidden data past specific markers, but does not describe whether it modifies files, required permissions, or output format. Lacks details on error handling when no data found.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with purpose and specific details. No superfluous words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description should at least hint at the return format (e.g., a heatmap image, coordinates list). It only says 'flagging high-entropy regions' without specifying how. Additionally, no information about supported image formats or error handling is provided. The tool's context is moderately covered.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds context that block_size controls the size of blocks for entropy calculation but does not add significant semantics beyond what the schema already provides for the two parameters.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries the full burden. It explains the detection logic but does not disclose whether the tool modifies the file, requires specific file attributes, or describes side effects. An agent needs to infer read-only behavior from context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences: first states purpose, second provides technical mechanism. No wasted words, front-loaded with essential information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequately explains what is detected and how, but does not specify the output format (e.g., boolean, confidence score, or evidence). For a complex detection tool, this omission may require the agent to assume standard output conventions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Single parameter 'file_path' is fully described in the schema (absolute path to JPEG file). The description adds no additional meaning beyond the schema's parameter description. Baseline score of 3 is appropriate due to complete schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: DFT magnitude spectrum analysis for spread spectrum steganography detection. It specifies that it computes the Discrete Fourier Transform of pixel values and analyzes the frequency spectrum for hidden signals, unusual peaks, or spectral flatness anomalies. This is specific and distinct from sibling tools like spread_correlation or spread_noise_analysis.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is used for detecting spread spectrum steganography in images, but it does not provide explicit guidance on when to use this tool versus alternatives. No mention of when not to use it or prerequisites, leaving the agent to infer context from the purpose alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

However, it does not disclose whether the tool modifies the file, or what the output format is. It is moderately transparent but could be more explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no extraneous words. First sentence states purpose, second details methods. Efficient and well-structured.

Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives. For example, it doesn't mention that other video tools like video_frame_lsb or video_eof_data might be more appropriate for targeted analysis. The agent must infer usage from the description alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It explains that comments can contain arbitrary data without affecting archive functionality (implying non-destructiveness), but does not explicitly state read-only behavior, permissions, or other side effects.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description should clarify what the tool returns (e.g., list of offsets, file types). It covers the core purpose and method but lacks details on output format, edge cases, or performance characteristics, leaving the agent with incomplete understanding for a scanning tool of this complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the schema already documents both parameters. The description does not add additional meaning beyond the schema; 'scan_depth' is already described in the schema as 'Bytes to scan (default: full file)'. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states that the tool scans for embedded files within a binary by searching for magic byte signatures, similar to binwalk. It explicitly distinguishes itself by focusing on hidden, appended files, and concatenated archives, which differentiates it from siblings like file_appended or file_strings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for binary file analysis via the binwalk analogy, but provides no explicit when-to-use or when-not-to-use guidance. No alternatives are mentioned among the many sibling tools, leaving the agent to infer context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It states 'visualize' and 'shows' implying a read-only operation, but does not explicitly confirm non-destructiveness or disclose any behavioral traits such as permissions or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with front-loaded purpose and immediate detail. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations present, so description carries full burden. It discloses the detection technique (PoV) and purpose but does not mention side effects, permissions, or output format. Adequate for a read-only analysis tool, but could add reassurance that it does not modify files.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no fluff. First sentence states main purpose, second adds specific anomaly detection detail. Ideal conciseness for a straightforward tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema defined, yet description fails to specify what the tool returns (histogram data, anomaly flags, or visual output). Without this, an AI agent cannot properly interpret the tool's results. Also lacks context on when to choose this over similar siblings like img_chi_square or img_rs_analysis.

It mentions that injected data is invisible to most parsers, but does not disclose potential side effects (e.g., file integrity, detection methods, permissions needed, or whether the operation is reversible). For a tool that modifies files, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no filler. The primary action and key behavior are front-loaded. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema is provided, but the tool's output (probably a file path or success status) is not described. With no annotations, the description should cover error conditions or prerequisites. It is functional but could be more complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the schema already describes parameters. The description adds context for 'data' (appended as string), but does not elaborate on file_path or output_path beyond what the schema provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the verb 'append' and resource 'after a file's end-of-file marker', distinguishing it from sibling tools like create_comment or create_metadata. The purpose is specific and unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description explains when to use (to hide data invisible to most viewers) and that it supports any file format. It does not explicitly mention alternatives or when not to use, but the context is clear enough given the sibling tool list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavioral traits. It mentions persistence and accessibility, but lacks details on permissions, reversibility, side effects, or error behavior for unsupported file types. For a mutation tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three sentences, front-loaded with the main purpose. No fluff. Efficient and to the point.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema; description explains file-type behavior but omits important context: what happens to original file (overwritten?), handling of other image formats, and output file specifics. Adequate but not thorough for a multi-format injection tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds value by explaining the injection format (tEXt/EXIF), providing context beyond the parameter descriptions. However, it doesn't clarify JPEG field naming conventions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Inject data into a file's metadata fields' and specifies the resource. It distinguishes behavior for PNG (tEXt chunk) and JPEG (EXIF APP1), which differentiates it from sibling tools like create_comment or jpeg_comment.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use (when metadata injection is needed) but provides no explicit guidance on when not to use it or how it compares to siblings like archive_metadata or doc_pdf_metadata. No exclusions or alternatives mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It explains the embedding method (3 bits per palette entry) and capacity but does not disclose whether the operation is destructive (overwrites LSBs), requires a certain palette size, or alters the image structure beyond LSBs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences, front-loaded with the main action, and contains no unnecessary words or redundancy. Every sentence provides essential information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the core functionality and capacity but lacks information about output format, error handling, or input validation. No output schema exists to supplement, so the description should be more comprehensive for a complete understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds context about the embedding mechanism but does not provide additional details beyond the schema for parameters like data encoding or file format constraints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Embed data in palette color entry LSBs for indexed-color images' and specifies file formats (PNG PLTE or GIF), distinguishing it from sibling tools like gif_palette_lsb (likely detection/extraction) and img_lsb_embed (for non-palette images).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for indexed-color images but does not explicitly state when to use versus alternatives (e.g., img_lsb_embed for direct-color) or when not to use (e.g., if palette has insufficient entries). No exclusion criteria are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It explains the extraction process (parsing /Info dictionary and XMP) but lacks details on error handling, file requirements (e.g., encryption), or return format. Basic transparency is adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with two sentences. The first states the core function, the second adds technical details and a use case. Every sentence is informative with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple tool (one parameter, no output schema), the description covers basic functionality and a use case. However, it does not specify the output format (e.g., returns a dictionary) or mention potential edge cases (e.g., missing metadata). This leaves some gaps for an agent to understand what the tool returns.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a clear description of the file_path parameter. The description adds the context that the tool extracts metadata, but does not provide additional details about parameter format, validation, or allowed values beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'PDF metadata extraction' with specific details about parsing /Info dictionary and XMP metadata. This distinguishes it from sibling tools like doc_xml_metadata (for XML files) and doc_pdf_hidden (for hidden content).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a use case ('forensic attribution and document provenance analysis') but does not explicitly guide when to use this tool over alternatives or specify exclusions. No comparison with sibling tools is made.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It explains the detection mechanism (testing equalization of adjacent pixel values) but does not describe the output format, return type, or behavior for non-stego images. This is a meaningful but incomplete behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with no redundancy. First sentence states the tool's identity, second explains the detection method. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a single-parameter detection tool, the description explains the technique but omits the expected output (e.g., boolean, score, detailed report). Given no output schema, this is a notable gap in completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There is only one parameter (file_path) with schema description 'Path to image file'. The description adds no additional meaning beyond the schema, so baseline 3 is appropriate with no added value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as a chi-square steganalysis attack for detecting LSB replacement, working on each color channel independently. It uses specific verb 'detects' and resource 'LSB replacement', and distinguishes from siblings like img_lsb_detect and img_rs_analysis by specifying the technique.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool should be used when LSB replacement detection is needed, but it does not provide explicit guidance on when to use this tool over alternatives (e.g., RS analysis, ensemble methods) or any exclusion criteria. Usage context is only implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full burden. It discloses file operations but omits details like maximum embeddable message size, effect on image pixels, or any irreversible changes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with no filler. The first sentence defines the action, the second adds process detail, achieving maximum efficiency.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 4 parameters and no annotations or output schema, the description covers the main action but lacks critical context like message capacity, requirements for source image, or behavior on failure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Parameter descriptions in the schema already explain each field (e.g., 'message' as 'Message to embed'). The description adds no new per-parameter meaning, meeting the baseline for 100% schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: embedding a message into an image using LSB steganography. It specifies the file type (PNG) and the process (reads, embeds, writes), effectively distinguishing it from sibling tools like img_lsb_extract.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It states it extracts bits, attempts UTF-8 decode, and shows hex dump, but lacks details on failure behavior, performance, or side effects. Adequate but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences, no extraneous words. First sentence states purpose, second expands on behavior with key details (channels, bit plane, decode, hex dump). Front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 5 parameters, no output schema, and many siblings, description covers core functionality but omits output structure and error conditions. It adds value with decode and hex dump context, but could be more complete.

Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. Description adds context about extracting from specified channels and bit plane, but this closely mirrors schema descriptions. The mention of UTF-8 decode and hex dump relates to output, not parameter semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Extract hidden data from image LSBs', a specific verb+resource. It distinguishes from siblings like img_lsb_detect (detection) and img_lsb_embed (embedding) by focusing on extraction and mentioning output details like hex dump and UTF-8 decode.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses the analysis scope but does not mention potential side effects, read-only nature, or performance impact, though 'analysis' implies a non-destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that front-loads the main purpose and lists specifics efficiently, with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description outlines what the tool examines but does not explain the output or return values (no output schema provided). For a simple analysis tool, it is moderately complete but could benefit from describing the nature of the results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for the single parameter (file_path). The description adds no further meaning beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs MP3 frame header analysis and lists specific aspects examined (bitrate changes, padding patterns, VBR detection, etc.), distinguishing it from sibling tools like mp3_detect or mp3_structure.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5

Good for a focused tool, but lacks return format details, prerequisites (e.g., image size compatibility), and error conditions. Siblings like qr_data_extract have more contextual depth.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All 3 parameters have schema descriptions (100% coverage). Description does not add significant value beyond schema, only hints at pixel-wise comparison. Baseline 3 is appropriate as schema already documents file paths and threshold.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clear verb 'Compare' with specific resource 'two QR code images'. Description details pixel-by-pixel comparison, module identification, and region analysis (data vs function). Distinct from siblings like img_compare (general) and qr_detect (detection only).

Three sentences; first sentence identifies purpose, rest provides technical context. No wasted words, efficient and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, and description does not hint at return values or result structure. Missing details on image format constraints (e.g., color vs grayscale) and how block size affects analysis. Adequate but incomplete for a detection tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with clear parameter descriptions. The description does not add meaning beyond the schema, so baseline 3 applies.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description lists what is checked but lacks information about output format (e.g., boolean, score, list of findings) or behavioral traits like handling of errors, performance, or limitations. Without annotations, the description carries the full burden and is only partially informative.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no filler, front-loaded with the main purpose and then listing checks. Every word adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with a single string input and no output schema, the description is somewhat incomplete: it does not describe the return value, how results are presented, or what 'unusual patterns' entails. Given the many sibling tools, more context would help an agent decide whether to use this tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with one parameter 'text' described as 'Text to analyze'. The description adds context about what the tool does with the text, but no additional parameter meaning beyond the schema.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose with specific verb 'auto-detect' and lists multiple detection categories (zero-width characters, whitespace encoding, invisible Unicode, homoglyphs, unusual patterns). It distinguishes from sibling tools like text_zwc_detect or text_whitespace_detect which are narrower in scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this vs. sibling tools. The description implies it's a comprehensive detector, but doesn't state scenarios where a more specific tool (e.g., text_homoglyph) would be better or how to interpret results.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description must fully disclose behavior. It explains detection of non-ASCII characters resembling ASCII letters, but does not describe the output format (e.g., list of found characters, locations) or any side effects. This leaves ambiguity about what the agent can expect after invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences that front-load the core purpose and provide an example. Every word adds value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool is simple with one parameter, the description omits what the output looks like (e.g., list, counts, or boolean). Given no output schema, this gap reduces completeness for an agent needing to handle results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% coverage with a single parameter 'text' described as 'Text to analyze'. The description adds no additional meaning beyond the schema; it only restates that the tool operates on text. Baseline 3 applies due to high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'Detect' and resource 'Unicode homoglyph substitutions in text', with clear examples (Cyrillic a vs Latin a). It distinguishes itself from siblings like text_detect or text_unicode_analysis by focusing on homoglyphs.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description states what the tool does but gives no explicit guidance on when to use it versus alternatives, nor any exclude conditions. Usage is implied but not clearly demarcated against sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided. The description states it 'checks' but does not clarify whether it is read-only, what the output looks like, or any side effects. Given the lack of annotation support, the description carries the full burden and does not sufficiently disclose behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

The description is three sentences long, front-loading the core action, then explaining the concept and use cases. Every sentence provides value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple detection tool with one parameter and no output schema, the description covers the purpose, input, and common use cases. It could optionally describe the return type (e.g., boolean or details) but is largely complete given the tool's simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The sole parameter 'file_path' is described in the schema as 'Path to ZIP archive', and the description reinforces that it is for a ZIP archive. With 100% schema coverage, the description adds meaningful context beyond the schema by specifying the file type context.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly specifies the action ('checks if a ZIP archive has prepended data') and the resource ('ZIP archive'). It distinguishes the tool from siblings like 'create_polyglot' and other archive tools by focusing on detection.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides context ('used in CTF challenges and to bypass file type filters') but lacks explicit guidance on when to use this tool versus alternatives like 'file_polyglot' or other detection tools. Usage is implied but not clearly scoped.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It states the tool 'identifies and hex-dumps gaps' and explains slack spaces are unused bytes that conceal data without altering functionality. However, it does not disclose whether the operation is read-only, any required permissions, or potential side effects like file modification.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no filler, highly efficient. Every sentence contributes to understanding the tool's purpose and behavior.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, but description adequately covers what the tool does and its main behavioral aspect (hex-dumping slack spaces). Lacks details on return values or handling of edge cases, but overall sufficient for a simple analysis tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema covers both parameters with descriptions. Description adds no further meaning beyond schema: file_path is simply 'Path to ZIP archive' and max_dump_size is 'Max bytes to hex-dump per slack space (default: 256)'. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden. It correctly indicates a read-only operation ('extract metadata') but does not disclose potential side effects, file size limits, or permission requirements. The format constraint (AVI) is clear.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that efficiently conveys purpose and output categories without unnecessary words. It is front-loaded and concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lists essential metadata categories (dimensions, FPS, codec, stream info, duration, file-level properties) which gives a good sense of the return value, especially since no output schema exists. Missing details on edge cases but adequate for typical use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only one parameter 'file_path' exists, and both the schema and description describe it as 'Path to AVI video file'. Schema coverage is 100%, so the description adds no additional meaning beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool extracts metadata from AVI video files and lists specific outputs (dimensions, FPS, codec, stream info, duration, file-level properties). This distinguishes it from sibling tools that perform other operations like frame extraction or detection.

Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, providing basic parameter descriptions. The tool description adds value by contextualizing block_size as 'section-by-section' and explaining the significance of high-entropy flags, which goes beyond the schema alone.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool calculates Shannon entropy per block and overall, flagging anomalous high-entropy sections. It specifies the resource (file) and the action (entropy analysis).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It explains the encoding scheme (space=0, tab=1) and the per-line checking, but does not mention limitations, output format, or false positives.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences that effectively front-load the purpose and method, with no extraneous words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the core purpose and detection mechanism well, but omits expected return value or result format. Given no output schema, this lack reduces completeness for a detection tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter 'text' has a minimal schema description ('Text to analyze'). The tool description adds significant meaning by specifying the expected content and detection logic, compensating for the schema's brevity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool detects whitespace encoding in text by checking for trailing whitespace patterns where spaces and tabs represent binary. It distinguishes from sibling tools like text_whitespace_extract and other text detection tools.

Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no extraneous information. The first sentence states the purpose, the second explains the mechanism. Every word contributes.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description explains the core mechanism but lacks details on output (the modified text is not mentioned), limits (max message length), and failure conditions. Given no output schema, some of this context would be helpful.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% parameter description coverage. The description adds value by explaining how the message is encoded and inserted, providing context beyond the schema strings 'Cover text' and 'Secret message to embed'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must convey behavioral traits. It describes the functional output (extracting data, checking statistics) but does not disclose whether the tool modifies files, requires permissions, or has performance implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, consisting of two sentences that efficiently convey the tool's function without unnecessary details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lacks details about return values or output format, and since there is no output schema, this is a gap. For a tool with two parameters, the description covers the main functionality but is incomplete regarding what the agent should expect in response.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so both parameters are documented. The description adds value by explaining the 'frame' parameter context (given frame index) and the analysis outputs (LSB distribution, balance, entropy), which go beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: detecting echo hiding in audio files via autocorrelation analysis. It specifies the method (normalized autocorrelation at common echo delays 50-1000 samples) and the indicator (unusually regular echo patterns). This distinguishes it from other audio steganography detection siblings like audio_lsb_detect.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is for echo hiding detection but lacks explicit guidance on when to use it vs. alternative audio stego detection tools (e.g., audio_lsb_detect). No mention of prerequisites or when not to use it, which is a gap given the many sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description adequately discloses behavior: tests all patterns, returns sorted matches with confidence, attempts decoding for top results. Lacks mention of potential limitations like false positives or performance impact, but covers main actions.

Implies use for analyzing ECC capacity and steganographic potential, but does not explicitly state when to use this tool versus alternatives like qr_structure or qr_module_analysis. No exclusion criteria or context provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full transparency burden. It details specific behavioral traits: examines modules for color variation, non-uniform grayscale, deviations from pure black/white, and links to LSB stego or watermarking. It does not cover return format or side effects, but the anomaly list is sufficiently informative.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences with zero wasted words. It leads with the action, lists specific anomalies, and ends with the purpose (stego/watermarking). Every sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of module-level analysis and the absence of an output schema, the description covers the tool's input (QR image with threshold), detailed anomalies, and high-level purpose. It could be more complete by mentioning the output format (e.g., a report of anomalies), but it provides enough context for an agent to decide invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with both parameters having descriptions (file_path and threshold). The tool description does not add new parameter information beyond the schema; it contextualizes the analysis but not the parameters themselves. Baseline 3 applies as the schema covers the parameters adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses specific verbs ('Examines individual modules') and clearly identifies the resource (QR code modules) and the anomalies sought (sub-pixel anomalies, color variation, LSB stego). It distinguishes from sibling tools like qr_detect and qr_compare by focusing on module-level pixel inspection.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for stego/watermark detection but does not explicitly state when to use this tool versus alternatives (e.g., qr_compare, img_lsb_detect). No when-not or alternative guidance is provided, leaving the agent to infer context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so description carries full burden. It lists detectable patterns but lacks details on behavior like read-only nature, error handling, or output format. Basic transparency is present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence that is well-structured and to the point. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and the description reinforces the purpose of each parameter, especially linking 'n' to nth_char mode. Adds meaning beyond schema by explaining modes in context.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool detects acrostic patterns (first-letter, first-word, etc.) across lines of text. This distinguishes it from sibling tools like text_detect or text_homoglyph which handle different text steganography techniques.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description implies usage for acrostic detection but does not explicitly state when to use it vs. alternative tools. No exclusion or comparison with siblings is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It indicates a read-only analysis operation by mentioning 'analysis' and 'structural map,' but does not explicitly confirm non-destructiveness or disclose additional behavioral traits like performance or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences with front-loaded purpose ('ZIP entry structure analysis'). Every sentence adds value, with no unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple input schema (one required parameter with clear description) and no output schema, the description fully explains what the tool does and what information it returns. It is complete for a one-parameter scanning tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences, zero waste. First sentence front-loads the purpose, second provides the technical method. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description explains the detection logic and parameters but does not mention the output format (e.g., returns true/false or a confidence score). For a detection tool with no output schema, this is a gap. File type restrictions are covered in schema, but overall completeness is adequate but not thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description does not add information beyond what the schema already provides for both file_path and threshold. The threshold's range and default are already in the schema description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it auto-detects BPCS steganography, specifying the verb 'auto-detect' and the resource 'BPCS steganographic embedding'. It explains the detection method (complexity map on all bit planes and channels) and mentions the signature of BPCS, which distinguishes it from siblings like bpcs_extract or bpcs_capacity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use when suspecting BPCS embedding, but it does not explicitly state when not to use it or suggest alternatives. The context is clear, but lacking explicit when-not advice keeps it from a perfect score.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Describes the decoding action and auto-detection behavior. No annotations provided, but description does not disclose any side effects, auth needs, or limitations. Adequate but not detailed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences front-loading all supported formats and the auto mode feature. No redundant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Provides core functionality but omits output format and error handling. Without output schema, agent lacks info on return value. Sufficient for simple usage but not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
States it is a decoder for multiple formats and mentions auto mode, implying use when decoding various encodings. Lacks explicit when-not or alternatives, but sibling context shows it is the only decoder.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It explains the process: locating all stream/endstream blocks, attempting zlib decompression, and reporting sizes and entropy. This is transparent about the tool's actions, though it does not mention if it modifies the file (assumed read-only) or any permission requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5

Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and no output schema, the description covers input and algorithm but omits output format (e.g., is the extracted message returned as a string? Is the original text modified?). This gap reduces completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The one parameter 'text' has minimal schema description. The tool description adds significant detail: it reads trailing whitespace and decodes space/tab binary. This compensates well for the sparse schema.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool extracts a specific type of hidden message (whitespace-encoded) and details the encoding scheme (space=0, tab=1 binary from trailing whitespace). It is distinct from sibling tools like text_whitespace_detect or text_zwc_extract.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use when text may contain whitespace encoding but does not explicitly state when to use versus alternatives (e.g., text_whitespace_detect). The context of siblings provides some differentiation but the description itself lacks direct guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses that the tool compares thumbnail and main image, which is non-destructive. It does not mention limitations or permissions, but the behavior is straightforward.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences: first states the action, second explains the forensic significance. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a one-parameter tool with no output schema, the description adequately explains what the tool does and what the result implies. It could mention the return format, but the interpretation is provided.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'file_path' has a schema description that already states its purpose. The tool description does not add any additional semantic meaning beyond that.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool compares the EXIF thumbnail against the main JPEG image, with specific forensic purpose (detecting modification after capture). This is distinct from sibling tools like img_compare or img_detect.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when investigating image authenticity or forensic artifacts, and explains what a mismatch indicates. However, it does not explicitly state when not to use it or provide alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, description carries full burden. It discloses computing three metrics and comparing two frames. However, it says 'adjacent' but parameters allow arbitrary indices, which is a minor inconsistency. Does not mention performance or error conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no wasted words. First sentence states purpose, second lists metrics. Efficient and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, description does not explain return format. It adequately covers what the tool does and metrics computed. Missing details on error handling or edge cases, but sufficient for a simple comparison tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, but description adds context: explains frame indices, default values, and file_path type (AVI). The term 'adjacent' adds meaning but conflicts with flexible indices. Adds value beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'compare' and resource 'adjacent video frames', and specifies purpose of detecting pixel-level anomalies with specific metrics (byte diff, MSE, PSNR). It distinguishes from sibling tools like img_compare and video_inter_frame.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description implies usage for steganography detection in video frames but does not explicitly state when to use this tool vs alternatives like video_inter_frame or img_compare. No exclusions or prerequisites mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries full burden. It clearly indicates a read-only analysis (no modification) and explains what computations are performed. It does not mention any side effects or permissions, but for a passive analysis tool this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the core purpose, and each sentence adds value without redundancy. No fluff or extraneous details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and no output schema, the description covers the what, how, and interpretation of results (IC values). It is sufficiently complete given the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has one parameter with description 'Text to analyze', and coverage is 100%. The description adds context on the analysis but does not enhance the parameter's meaning beyond what the schema provides. Baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it performs character frequency analysis for cryptanalysis, including counting occurrences, comparing to standard English letter frequency, and calculating Index of Coincidence. This specific verb+resource job distinguishes it from siblings like crypto_detect or crypto_entropy.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description tells when to use it (cryptanalysis frequency analysis) and provides interpretation guidelines for IC values. However, it does not explicitly state when not to use it or mention alternatives, though the sibling context implies differentiation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully describes behavior: it reports size comparison, first N differences with offsets and values, percentage of identical bytes, and summary. No destructive actions are implied. The description is transparent and accurate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long, front-loaded with the main purpose ('Binary diff between two files'). Every sentence adds value, with no waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Although there is no output schema, the description explains the return values in sufficient detail (size comparison, differences, offsets, values, percentage, summary). For a comparison tool with only two parameters, this is complete enough for an agent to understand usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions like 'First file path' and 'Second file path'. The description does not add meaning beyond what the schema provides. Baseline 3 is appropriate as the schema already documents the parameters adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs a binary diff between two files, comparing byte-by-byte. It specifies the outputs (size comparison, differences, offsets, values, percentage identical, summary). This distinguishes it from sibling tools like file_strings or file_hex.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states the tool is useful for detecting steganographic modifications, providing a clear use case. It doesn't explicitly list when not to use it, but the purpose is well-defined, implying it's for binary comparison scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully discloses the read-only visualization behavior and the types of data shown (chunks, FourCC, offsets, sizes). It does not mention performance or file size limits, but the core behavior is transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two brief sentences convey all necessary information without redundancy. Every word adds value, and the description is front-loaded with the key action and output.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple input (one parameter) and no output schema, the description fully explains the tool's purpose, input, output format (tree with chunks, FourCC, offsets, sizes), and use case (forensic analysis).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single parameter file_path. The description adds context by specifying AVI/RIFF file type, which enhances understanding beyond the schema's 'Path to AVI video file'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool visualizes AVI/RIFF chunk structures as a tree, detailing chunks, FourCC codes, offsets, and sizes. This specific verb-resource pair distinguishes it from sibling video tools like video_metadata or video_detect.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for forensic analysis of container structure, providing clear context. However, it does not explicitly state when to use this tool over alternatives or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It thoroughly discloses what the tool checks (slack spaces, prepended data, appended data, extra fields, comments), giving a clear understanding of its behavior. It implies read-only detection.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
