Server Quality Checklist

67%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v2.5.3

  • Disambiguation5/5

    All 24 tools have clearly distinct purposes, covering memory operations, project management, role contracts, and injection features. No two tools appear to overlap in functionality.

    Naming Consistency3/5

    Two naming conventions are used: a 'chainmemory_' prefix for core blockchain operations and a verb_noun pattern for project/role/injection tools. While internally consistent, the mix reduces predictability.

    Tool Count4/5

    24 tools is on the higher end but appropriate for the server's domain, which spans memory management, project lifecycle, roles, and blockchain interactions. Each tool has a clear role.

    Completeness3/5

    Covers most core operations but lacks a tool to delete a memory (only archive) or update memory content beyond tags. These gaps could cause workflow interruptions.

  • Average 3.8/5 across 24 of 24 tools scored. Lowest: 2.9/5.

To manually sync the server, click the "Sync Server" button in the MCP server admin interface.

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?

    No annotations provided; description is a simple verb+noun with no additional behavioral details such as side effects, permissions, idempotency, or uniqueness constraints. The tool is a creation operation, but the description offers no extra transparency.

    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?

    Single sentence with no redundancy. It is concise, though it could be more informative without losing brevity.

    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 no output schema and 3 parameters, the description fails to explain what 'project tag' means, success/error results, or constraints. It is minimal and leaves significant gaps for the agent.

    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% already providing descriptions for all three parameters. The description adds no further meaning beyond what is in the schema, so baseline score of 3 applies.

    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?

    Description states 'Create a new project tag' which clearly indicates the action and resource. However, 'project tag' is slightly ambiguous as sibling tools suggest 'project' is the main entity. Still specific enough for an AI agent to understand.

    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 on when to use this tool versus alternatives like 'add_project_from_template' or 'list_projects'. The AI agent is left to infer context from sibling names.

    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?

    Description does not disclose that tags are replaced (not appended). No mention of side effects, authorization needs, or impact on memory associations. Schema description covers replacement detail, but main description lacks transparency.

    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, efficient and front-loaded. Could include replacement behavior but remains appropriately sized for a simple update 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?

    Description is minimal for a mutation tool with no annotations or output schema. Lacks details on tag replacement behavior, return values, or error states. Incomplete for an agent to fully understand the tool's behavior.

    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. Description adds minimal semantic value by explaining tags as project labels, but does not elaborate on memory_id or provide additional meaning 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?

    Description clearly states verb 'Update' and resource 'tags of a memory'. Explains tags as 'project labels for organization.' Differentiates from sibling tools like archive_memory by focusing specifically on tags.

    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 on when to use this tool versus alternatives like list_memories_filtered or archive_memory. Does not mention prerequisites or conditions for usage.

    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 cover behavior. It mentions a cost detail for 'Selective inject' which is irrelevant to checking balance, potentially confusing the agent. Does not clarify if the balance check itself has side effects or costs.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences; the first is concise and clear. The second sentence about inject cost is irrelevant and adds clutter. Could be more focused.

    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 or annotations. Lacks return format, units, or confirmation that it's a read operation. The irrelevant cost detail does not compensate for missing complete context.

    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?

    No parameters, so baseline is 4. The description adds the cost note which doesn't relate to parameters. Does not explain what the tool returns or how to interpret the balance. Adequate but not helpful.

    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 the verb 'Check' and resource 'user's AIC balance', directly indicating the function. Distinguishes from siblings like get_inject_history which deals with history, not balance.

    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. The description implies use for checking balance but does not provide context or exclusions.

    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 full burden. It mentions return content for the owner but does not disclose pagination, ordering, or behavior for non-owners. It also lacks statements about read-only nature or potential 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.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, efficient and to the point. It front-loads the main action and filtering options, with no wasted words. Could be slightly improved by breaking into two sentences for readability.

    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 list tool with no output schema, the description covers the basics but lacks information on pagination, ordering, and behavior when no results are found. It is minimally complete but could be more comprehensive.

    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 adds value by providing defaults (limit: 50), conventions (use 'general' for untagged), and default behavior (archived false). This goes beyond the schema definitions.

    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 lists memories with filtering by project tag and archived status, and specifies the return content (metadata + plaintext for owner). However, it could better differentiate from sibling tools like 'chainmemory_recall' which might also list memories, but the name implies filtering is the differentiator.

    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 filtered retrieval by project or archived status, but does not explicitly state when to use this tool over siblings, nor does it mention when not to use it. No alternatives are 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?

    Without annotations, the description should disclose behavioral traits. It only states the action but omits side effects, such as whether the memory becomes active again or if any access restrictions apply. The description adds minimal value beyond the tool name.

    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 concise sentence with no extraneous words, efficiently conveying the core purpose.

    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 tool's simplicity (one parameter, no output schema), the description is minimally adequate. However, it lacks context such as preconditions (memory must be archived) or postconditions (memory is restored), which 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%, with the parameter 'memory_id' described in the schema as 'Your memory number to restore (the # shown in recall)'. The description does not add further meaning, 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 'Restore an archived memory' uses a specific verb and resource, clearly indicating the action of reversing an archive. It distinguishes itself from the sibling tool 'archive_memory' which performs the opposite operation.

    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. It does not state prerequisites (e.g., memory must be archived) or conditions for use, leaving the agent to infer context from the tool name 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 are provided, so the description carries the full burden. It does not disclose behavioral traits such as whether the operation is read-only (implied but not explicit), pagination behavior, rate limits, or authentication needs. The only hint is the 'limit' parameter, which suggests pagination is possible but not stated.

    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 the tool's purpose and key output fields. 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?

    Given the tool's simplicity (one optional parameter, no output schema), the description is mostly complete, mentioning the return fields. However, it could specify ordering (e.g., chronological) or that the history is user-specific.

    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 one parameter (limit) with 100% description coverage (min, max, default). The tool description does not add any additional meaning beyond the schema. 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 states a specific verb 'Get' and resource 'history of selective inject operations', and lists included fields (timestamps, memory counts, costs, tx hashes). It clearly distinguishes from sibling mutation tools like inject_memories or chainmemory_*.

    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 information on when to use this tool versus alternatives, no exclusions, and no prerequisites. It simply states what it does without 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 only reveals it is a read operation, but omits details on output format, pagination, 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?

    Single sentence, no wasted words, perfectly concise.

    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?

    Adequate for a zero-parameter tool, but lacks output schema details and any behavioral context beyond listing.

    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?

    Zero parameters with 100% schema coverage, so no additional semantics needed; baseline 4 applies.

    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 'List' and resource 'projects' with a parenthetical definition, distinguishing it from sibling tools like create_project or delete_project.

    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 on when to use this tool vs alternatives, nor any exclusions or prerequisites.

    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. It implies a read operation and lists expected fields, which is sufficient for a simple getter. However, it does not disclose any side effects, rate limits, or 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?

    The description is a single sentence that effectively lists the returned fields with no extraneous information. Every word 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?

    For a simple tool with one optional parameter and no output schema, the description provides enough information for an agent to understand the tool's purpose and what it returns. It is complete for the level of 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 description coverage is 100% for the single parameter ai_id (with description 'AI ID (omit for own)'). The tool description does not add further meaning beyond what the schema already provides, so a 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 'Get this AI's profile' as the verb+resource, and explicitly lists the fields returned (name, model, memory count, trust score, registration block). This distinguishes it from sibling tools like chainmemory_stats or get_my_context.

    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. While the purpose is clear, there is no explicit statement of context 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 provided, so description must cover behavior. It notes 'on-chain' registration and one-time requirement, but omits side effects, costs, or return value for this write 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?

    Two short sentences, no redundancies, directly communicates purpose and prerequisite.

    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 output schema or annotations, description lacks return information and fails to fully describe registration outcome, leaving the agent guessing about success indicators.

    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 both parameters (100% coverage). Description adds no extra semantics beyond what schema already provides ('AI name', 'Model name').

    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 'Register' and resource 'AI identity on-chain', and distinguishes from siblings by noting it's a prerequisite for writing memories.

    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?

    Explicitly states 'Required once per AI before writing memories', giving clear context. Does not name alternatives, but the scope is clear.

    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 discloses that memories keep the tag but project metadata is removed, providing some insight into non-destructive behavior. However, with no annotations, more detail on irreversibility or permissions would be beneficial.

    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 redundant information. The key action and side effect are conveyed efficiently.

    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 delete tool with one parameter, the description adequately covers the main behavior and consequence. Minor gap: no mention of return value or error conditions, but not critical given simplicity.

    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 clear description. The tool description adds no additional parameter-level information, so baseline score 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 deletes a project tag and explains the effect on memories, distinguishing it from other project-related tools. The verb 'delete' and resource 'project tag' are specific.

    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 on when to use this tool versus alternatives like updating project state or archiving. No mention of prerequisites or conditions.

    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 mentions sessions auto-release after 60 minutes, providing helpful timeout behavior, but does not disclose whether the action is reversible, required permissions, or side effects on session data.

    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?

    Description is concise: one sentence with parenthetical detail and a separate sentence about auto-release. No redundant information, 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?

    Missing return value description (e.g., success confirmation, error states) and preconditions (session must exist, ownership). The auto-release note adds context but overall leaves gaps for a tool with no output schema and no annotations.

    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 50% (session_id lacks description). The description adds value by elaborating on the summary parameter ('what was done, what is pending, next step'), exceeding the schema's brief 'Closing summary for the audit trail'. session_id remains implicit but is a standard identifier.

    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 releases an open Role Session with a closing summary, specifying the summary content. It does not explicitly differentiate from sibling tools like assume_role, but the action is distinct.

    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 when an open role session exists, but does not provide explicit when-to-use or when-not-to-use guidance, nor mention alternatives like waiting for auto-release.

    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 should disclose behavioral traits. It only states the operation, not whether it's read-only, side effects, or permissions needed.

    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 concise sentence with no redundancy. Front-loaded with purpose, lists categories efficiently.

    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, parameterless tool with no output schema, the description is complete: it identifies the resource (built-in project templates) and the scope (listed categories).

    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?

    No parameters, schema coverage 100% trivially. Description adds value by listing categories, confirming no input needed, and providing context beyond empty 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 it lists built-in project templates, enumerating specific categories (general, development, blockchain, business, personal, research), distinguishing it from siblings like add_project_from_template.

    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 on when to use this tool versus alternatives (e.g., before calling add_project_from_template). Context of usage is implied but not explicit.

    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 discloses that the action is reversible and what changes (stops appearing in recall/inject). However, missing details on required permissions or impact on other operations.

    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 efficient sentences that convey purpose, effect, and reversibility with no fluff.

    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 tool with one parameter and no annotations or output schema, the description is fairly complete. It explains the behavioral change and reversibility. Could optionally mention if there's any confirmation step.

    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 good parameter description. The description adds 'stops appearing in recall and inject lists' which complements the schema but does not significantly extend beyond it.

    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 the tool archives a memory and explains the effect (stops appearing in recall/inject, remains on-chain, reversible). Distinguishes from siblings like delete_project and unarchive_memory.

    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?

    Implied usage through explanation of effect (archive vs. delete), but no explicit when-to-use or alternatives guidance. More context could help distinguish from unarchive_memory or update_memory_tags.

    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; description mentions permanent encryption, auto-tagging, and importance range. Lacks details on side effects, overwrite behavior, or full encryption process, but covers core traits.

    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 key information front-loaded: action, encryption, auto-tagging, importance, use cases. No filler or repetition.

    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 write tool with 7 parameters and no output schema or annotations, the description covers the main purpose, key parameter usage (importance, encryption), and appropriate use cases. Could briefly mention that summary is required, but it's in schema.

    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 3. Description adds minimal extra meaning: notes content as full memory, summary as what will be encrypted, tags as explicit with auto-tagging fallback. Does not elaborate on category enum 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?

    Description clearly states 'Write a permanent encrypted memory to ChainMemory' with specific verb and resource, and mentions auto-tagging and importance scale. Distinguishes from sibling tools like chainmemory_recall and list_memories_filtered.

    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?

    Says 'Use for important decisions, learnings, milestones the user wants permanently recorded,' providing context but not explicitly contrasting with alternatives like inject_memories or specifying 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.

  • Behavior3/5

    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 states the tool fetches stats but does not mention if the operation is real-time, cached, expensive, or requires any authorization. Basic disclosure without depth.

    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 front-loaded with the verb and resource, followed by a concise list of returned stats. 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?

    Given the tool has no parameters, no output schema, and a simple purpose, the description is largely sufficient. However, it lacks information about the return format, error cases, or potential rate limits.

    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?

    With zero parameters, the baseline is 4. The description adds value by enumerating the fields returned (total AIs, memories, current block, AIC supply), which provides meaning beyond the empty 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 uses a specific verb 'Get' and resource 'ChainMemory network stats', and lists the exact statistics returned (AIs, memories, block, supply). This clearly distinguishes it from sibling tools that deal with CRUD operations, memories, or role management.

    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 when network stats are needed, but provides no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. Usage is implied through 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?

    With no annotations provided, the description carries full burden. It discloses that the tool returns a 'condensed summary plus recent memories' with 'cryptographic verification status', implying a read-only operation. However, it lacks details on authentication, rate limits, error conditions, or behavior when no memories exist.

    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 no wasted words. It front-loads the core purpose and then adds the usage recommendation, making it efficient and easy to parse.

    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 explains the return value (condensed summary + memories + verification) and the use case, compensating reasonably for the lack of output schema. It could elaborate on the 'condensed summary' format or include examples, but overall it is sufficient for the tool's moderate 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?

    The input schema covers both parameters with descriptions (limit and verified_only). Since schema description coverage is 100%, the description adds no additional meaning beyond what is already provided in the schema, which aligns with the baseline of 3.

    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 action ('Retrieve') and the resource ('user's portable, verified AI conversation history from ChainMemory'). It distinguishes the tool from siblings by specifying it returns a condensed summary plus recent memories from multiple platforms with cryptographic verification status, and explicitly recommends using it 'at the start of a conversation'.

    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 advises using this tool 'at the start of a conversation to provide continuity across AI providers', which is clear usage context. However, it does not explicitly mention when not to use it or compare to sibling tools like list_memories_filtered or chainmemory_recall.

    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 key behaviors: cost (0.001 AIC per call up to 50 memories), return format (plaintexts), deflationary tokenomics, and optimistic mode. It does not mention side effects on the memory store or error handling, but covers the most important aspects.

    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 (5 sentences), front-loaded with the core action, and contains no unnecessary information. Every sentence adds useful context.

    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 tool with 3 parameters, no output schema, and no annotations, the description covers purpose, cost, behavior, and optimization. It explains what the tool returns (plaintexts) but lacks error conditions or prerequisite checks like balance requirements.

    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 clear parameter descriptions. The tool description adds no new semantic value beyond what the schema already provides for memory_ids, project_filter, and target_platform.

    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 specific action (Inject selected memories into current conversation context), using a precise verb and resource. It distinguishes from sibling tools like chainmemory_remember or chainmemory_recall by focusing on injection into active context.

    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 injecting memories into conversation context but does not explicitly state when to use this tool versus alternatives. No exclusions or when-not-to-use guidance is 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 provided, so description carries full burden. It states the action but does not disclose side effects, idempotency, error scenarios, or return behavior. Adequate but lacks depth for a mutation 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 sentences, no wasted words. First sentence defines purpose, second gives usage guidance. Front-loaded and efficient.

    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 tool with one parameter and no output schema, the description is fairly complete. It defines the action and prerequisite. Could mention outcome confirmation but not essential.

    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 covers 100% of parameters with a description. Description adds an example value ('blockchain') and prerequisite context, providing meaning 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?

    Clearly states it instantiates a built-in template as a user project, distinguishing it from create_project which likely creates from scratch. References sibling list_project_templates for prerequisite step.

    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?

    Explicitly tells agent to use list_project_templates first to see available IDs, providing clear context for when to use this tool. No explicit when-not or alternatives, but the guidance is strong.

    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 provided, so description carries full burden. It discloses that the action is permanent ('Cannot be modified after'), requires an environment variable, and is a direct contract call. This is sufficient for a simple irreversible action.

    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 concise sentences, no wasted words. The core purpose is front-loaded, and each sentence adds necessary detail without redundancy.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use (to make a memory immutable) and notes a prerequisite (AICHAIN_KEY env var). However, it does not explicitly state when not to use or provide alternative comparisons.

    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 provided, the description fully covers behavioral traits: server validates invariants, applies via deterministic builder, computes state_hash, and persists. It also warns against including credentials. The architecture is explained, though rate limits or specific side effects are not mentioned.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity and lack of output schema, the description adequately covers purpose, usage, and parameters. However, it does not describe return values or error handling, which would be helpful for a tool that performs complex server-side validation and persistence.

    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%, and the description adds meaningful context beyond the schema. For 'ops', it details the 29-op grammar, explains evidence_memory_ids usage, and warns about credentials. For 'consolidated_until_event', it clarifies its role as a watermark. The description enhances understanding beyond schema descriptions.

    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: proposing structured operations to update a project's consolidated state (Project Brain). It uses specific verb+resource and explains the architecture, distinguishing it from sibling tools like get_project_state and list_memories_filtered.

    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?

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Discloses fee, pinning of contract version+hash and Brain state_hash, and the constraint of one open session per role. While no annotations are present, the description covers key behavioral traits. Could be more explicit about idempotency or error states.

    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?

    Four sentences pack critical information: action, fee, pinned data, constraints, and pairing with release_role. No redundant information; front-loaded with the essential purpose.

    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 sibling tools and lack of output schema, the description adequately explains the tool's role in the workflow (session open/close). It covers prerequisites, constraints, and side effects. Could mention return value or error conditions for more 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?

    The description mentions 'project' and 'role_id' implicitly through the narrative, but does not explicitly describe the parameters. The optional 'platform' parameter is not discussed. Schema description coverage is low (33%), and the description partially compensates by contextualizing the required parameters but not the optional one.

    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 the tool assumes a project role under a Verifiable Role Contract, opening an audited Role Session with a specified fee. Distinguishes from sibling release_role by framing it as the opening counterpart.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly states when to use: at session start, with active contracts only, and that only one session per role is allowed. Provides the complementary action (release_role) and the prerequisite (active contract).

    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 full burden. It indicates recall (a read operation) and returns plaintext, implying it's non-destructive. However, it does not explicitly state that it is read-only or safe, which would be ideal but is reasonably inferred.

    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?

    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 compensates by listing many output fields and features (integrity, owner-scoping). Lacks error handling or response format details, but sufficient for a retrieval 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?

    The only parameter 'name' is fully described in the schema; the tool description adds no extra details beyond the schema's description, 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 action ('Get') and the resource ('consolidated, verifiable STATE of a project'), specifies the output structure, and distinguishes it by noting owner-scoping and use case ('instead of re-deriving context').

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Provides explicit when-to-use guidance ('at the START of work on a known project') and the rationale ('instead of re-deriving context'), with implicit distinction from write tools like update_project_state.
