Server Quality Checklist

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

Latest release: v1.0.0
Disambiguation5/5
Each tool has a clearly distinct purpose, with detailed descriptions that prevent confusion even among similar operations (e.g., cp vs push_staged_file, get_logs vs get_deploy_log).
Naming Consistency5/5
All tools follow a consistent appcrane_verb_noun pattern (e.g., create_app, list_apps, set_secret, deploy). No mixing of conventions or vague verbs.
Tool Count3/5
With 35 tools, the server is on the heavy side. While the scope is broad (full app lifecycle management), the number exceeds the typical 25+ threshold, making it feel slightly oversized. Some consolidation could be considered.
Completeness5/5
The tool set covers the entire app lifecycle: creation, deployment, configuration, access control, file operations, logs, health, analytics, and request management. No obvious gaps for the stated purpose.

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

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations were provided, so the description alone must convey behavioral traits. It explains that the tool bypasses the auth proxy, hits the configured health endpoint directly on the internal port, and returns response status and body. This provides useful insight into the tool's mechanics. However, it does not describe error handling (e.g., what happens if the app is down or the endpoint is missing), which would improve transparency.
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 paragraph with no wasted words. The first sentence states the core function, the second provides use cases, the third explains internal behavior, and the fourth gives parameter guidance. Every sentence serves a purpose, and the layout is 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?
For a simple health-check tool with two parameters and no output schema, the description covers the essential aspects: purpose, use cases, internal behavior, and parameter default. It mentions the return includes status and body. However, it lacks information about possible errors or failure modes, which would enhance completeness for an 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?
The schema already describes both parameters fully (slug with example, stage with enum and default). The description adds value for the stage parameter by clarifying when to use 'production' vs 'sandbox'. However, no additional semantics are provided for slug. Given 100% schema coverage, the baseline is 3, and the added context for stage is sufficient to maintain that score.
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 that the tool fetches the health endpoint server-side, bypassing the auth proxy. It identifies two specific use cases: validating a deploy and checking if the app is responding. While it doesn't explicitly differentiate from sibling tools, the purpose is concrete and not a tautology.
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 provides explicit contexts for using the tool: 'to validate that a deploy actually landed the expected version, or to check if the app is responding.' It also gives a specific guideline for the stage parameter: 'Defaults to sandbox; pass stage="production" only when the user asks about prod.' No explicit exclusions or alternatives are mentioned, but the guidance 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?
No annotations provided, so description is the sole source. It discloses that results are newest first and includes return fields, but lacks details on error handling, pagination, or whether the operation is read-only. The description adequately implies a safe, read-only 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 sentences that front-load the core purpose and return fields, then give usage guidance. Every sentence earns its place with 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 no output schema, the description adequately covers the return fields and purpose. It mentions limit/ordering indirectly via 'newest first' but does not describe pagination or error scenarios. For a list tool with clear parameter defaults, this is reasonably 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 67%, below the 80% threshold for baseline 3. The description adds meaning by stating 'for an app + env' (mapping to slug and stage), but does not detail slug format or the limit parameter's effect. This provides moderate added value over 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 the tool lists deploy/release history for an app+env, newest first, with specific fields. It distinguishes itself from siblings by mentioning its use for picking a target for appcrane_rollback.
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 says 'Use this to see what is live and to pick a target for appcrane_rollback' and notes 'App access required,' providing clear context for when to use it. It does not explicitly state when not to use it, but the guidance is sufficient.
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 encryption at rest, that only the running app can read plaintext, defaults to sandbox, and admin requirements. However, it does not mention whether setting a secret triggers any deployment or restart, nor does it discuss overwriting behavior 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is four sentences, concise, and front-loaded with the purpose. 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?
The description covers encryption, permissions, stage default, and scope. It lacks details on value size limits or key validation, but for a simple write tool, it is fairly complete. No output schema exists, but the tool's return is not complex.
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 75% (3 of 4 parameters have descriptions; slug lacks description). The description adds context about encryption and stage defaults, but does not elaborate on each parameter beyond what the schema provides. Baseline 3 is appropriate given the 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 'Set or update a secret (an encrypted environment variable injected into the app).' It uses a specific verb (set or update) and resource (secret), and explains what a secret is, distinguishing it from sibling tools like appcrane_get_secret.
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 provides guidance: 'Defaults to sandbox; require explicit stage="production" only when the user asks.' And 'App-admin or AppCrane admin only.' It also mentions scope respect. It does not explicitly state when not to use, but the context 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?
With no annotations, the description must carry full burden. It mentions data source ('app_visits') and access restrictions ('Admin only') but does not explicitly state that the tool is read-only or non-destructive. More transparency about safety 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, front-loaded with the key purpose, and every sentence adds value. 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?
For a simple list tool, the description provides sufficient context: what it does, data source, use cases, and access. Lack of output schema means an agent must infer return structure, but the description's clarity compensates mostly.
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 descriptions for both parameters (top and days). The tool description adds no additional meaning beyond what the schema already provides, resulting in a baseline score.
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 'Top users by distinct apps opened in a lookback window' with a specific verb ('surfaces') and resource ('top users'). It distinguishes itself from sibling 'appcrane_top_apps' by focusing on users rather than apps.
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?
Explicit use cases are provided ('finding power users to interview, or spotting churn risk') and context like 'Active users only' and 'Admin only' gives clear when-to-use guidance. However, it does not mention when not to use or 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?
No annotations provided, so description carries the burden. It discloses the timing constraint (after most recent deploy) and output contents. Does not explicitly state read-only nature, but the verb 'list' implies it. Role requirement mentioned. Could be more explicit about permissions.
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 covers purpose and output, second covers usage and role. Front-loaded, no redundant information.
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 explains return fields. Covers source, timing, and target users. Could mention potential pagination or limits, but overall sufficient 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?
Schema description coverage is 50% (stage has description, slug does not). Description implies slug identifies the app but adds no new details for slug. For stage, it replicates the schema info ('omit to list both envs'). Description does not fully compensate for missing 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?
Description clearly states the tool lists scheduled jobs from an app's deployhub.json cron array, with specific fields included. It is distinct from sibling tools like appcrane_run_cron_now.
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 says to use for verifying registration, debugging missing runs, or reading logs. Identifies target users as app-admin or owner. Lacks explicit alternatives or when-not-to-use, but context is clear.
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 bears the burden of disclosing behavior. It explains return fields (id, message, app_slug, submitter, bucket), bucket meanings, and that omitting slug shows all accessible apps. It lacks details on ordering or pagination but covers essential behavioral 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?
The description is concise with three sentences: one for purpose and use cases, one for return fields, and one for bucket explanations and a tip. No extraneous information; 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 no output schema and 3 parameters, the description covers purpose, usage context, return fields, bucket definitions, and a filtering tip. It omits sorting and error handling but is sufficient for an agent to select and invoke the tool correctly in most scenarios.
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 67% (slug and bucket described, limit not). The description adds value by reiterating the bucket filter tip and confirming slug omission behavior, but does not elaborate on the limit parameter beyond what the schema provides (default, min, max). 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 explicitly states the tool lists enhancement requests from the AppCrane intake form and provides concrete use cases like 'what should I work on?' and 'what's queued for X?'. It clearly distinguishes from sibling listing tools (e.g., list_apps, list_releases) by focusing on requests with bucket categorization.
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 the tool (user asks about work items, picking up tickets) and suggests filtering by bucket='triage' to find unclaimed work. It doesn't explicitly mention when not to use alternatives, but the sibling context and specific bucket guidance provide adequate direction.
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 the full burden. It discloses idempotency, permission requirements, and the only-owner protection, which are critical behavioral traits beyond the schema.
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, front-loaded with the main action, and no wasted words. Efficiently covers key points.
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 two-parameter tool, the description covers input, behavior, permissions, and edge cases. It lacks explicit output format, but the tool's simplicity makes this omission acceptable.
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 50% (only 'user' has a description). The description does not add explicit param details beyond the schema context, but the app context implies 'slug' is the app identifier. Adequate but not compensatory.
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 'Remove' and the resource 'user access from an app', distinguishing it from sibling tools like appcrane_grant_app_access.
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 provides explicit guidance on idempotency, required permissions (app-admin, owner, global admin), and a special case (refuses to remove the only remaining owner). It lacks explicit comparison to alternatives but is clear enough.
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?
The description discloses data source (app_visits, Caddy forward_auth), ordering (by user count descending), and access restriction (Admin only). This exceeds what structured fields provide, though it lacks details on edge cases like empty results.
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, each serving a distinct purpose: purpose, use cases, data source, ordering and access. No wasted words, front-loaded with key information.
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 covers return ordering and data source. It is adequate for a simple list tool but could mention error handling (e.g., non-admin access).
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 both parameters have clear descriptions. The description reinforces 'lookback window' and 'how many rows' but adds no new information beyond the schema, resulting in baseline score.
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: 'Top apps by distinct active users in a lookback window' and provides concrete example questions that differentiate it from siblings like appcrane_top_users.
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 includes example use cases ('which apps are getting the most use this week') but does not explicitly state when not to use the tool or name alternatives. However, the context is adequate for typical usage.
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 full burden. It explains partial updates ('Only includes fields you pass; omitted fields are left alone'), how to clear a string field (empty string), and token encryption ('Stored encrypted (AES-256-GCM)'). It also indicates the return shape. Missing are side effects like triggering a redeploy or rate limits.
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 tight sentences with front-loaded purpose. Every phrase adds value: the verb 'patch', immediate use cases, the scoping statement, clearing instructions, and return reference. No redundancy or 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?
Given no output schema, referencing appcrane_get_app for return shape is appropriate. The description covers the core behavior (partial update, clearing fields). However, given the tool's complexity (16 params), it could explain interactions or constraints (e.g., required slug but not other required fields) but is adequate overall.
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 low (38%), so the description must compensate. It adds meaning for several parameters (github_url, token, branch, category, visibility, resource limits) but fails to cover many others (name, slug, domain, description, source_type, public_access, frame_ancestors, image_retention). The added value is moderate but incomplete.
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 patching operation for existing apps, listing specific use cases (fix github_url, change branch, rotate token, etc.) and distinguishing it from general app management by noting it handles 'anything you would otherwise need direct DB access for.' The verb 'patch' contrasts with other sibling tools like appcrane_create_app.
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?
Explicit use cases are given ('fix a missing github_url... change branch... rotate the github_token...'), providing strong when-to-use guidance. However, it does not explicitly state when not to use or mention alternatives (e.g., appcrane_set_app_meta for metadata changes) or prerequisites, so it falls short of a 5.
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 describes the return content and error behavior (404-equivalent). For a read-only tool, this is adequate transparency.
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 covers purpose, second covers usage and error. Every sentence is valuable and front-loaded. No redundant information.
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?
Despite no output schema, the description fully explains the return content (URLs, versions, deployments, health) and error case. Complete for a simple 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?
Schema coverage is 100% with a well-described slug parameter. The description adds no new parameter meaning beyond the schema, so baseline 3 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?
The description clearly states it retrieves detailed info for a single app, listing specific data types (URLs, versions, deployments, health). It distinguishes from siblings like appcrane_list_apps or appcrane_get_health by focusing on a single app's comprehensive status.
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 when to use the tool (e.g., ask about status, after deploy) and mentions error cases. Does not explicitly exclude alternatives, but the specificity is sufficient.
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 the full burden. It discloses that releases re-use cached images (no rebuild if retained), health-checks occur, a new deployment is recorded, and the previous one is marked rolled_back. Access restrictions are stated. Missing potential failure scenarios, but overall 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?
Three sentences: purpose, parameter behavior, and execution details. Each sentence adds unique value with no repetition. Front-loaded with the core 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?
No output schema, so the description should explain return values or error conditions. It mentions health-checks but not failure handling or the response format. For a mutation tool with side effects, this is a gap, but the core behavior is well-covered.
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 67% (2 of 3 parameters described in schema). The description adds context: deployment_id is sourced from list_releases, the two rollback modes, and stage as legacy alias. It compensates for the undocumented slug parameter by implying its role as the environment identifier.
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 begins with a clear verb and resource ('Roll an env back'), specifies two modes (target specific release or roll back to previous), and distinguishes from sibling tools like appcrane_deploy or appcrane_promote by its unique rollback purpose.
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 explains when to provide deployment_id vs omit it, references a source tool (appcrane_list_releases), and notes owner-only access. It does not explicitly exclude alternatives, but the usage is sufficiently clear for an agent.
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?
Despite no annotations, the description thoroughly discloses behavior: idempotent (skips if already running), runs docker exec, updates metadata, and returns exit code and log. Authorization implied ('App-admin or owner').
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?
Fairly concise, front-loaded with main purpose, and efficiently covers use cases and behavior in a few sentences. Could be slightly shorter, but nearly ideal.
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?
No output schema exists, but the description explains returns (exit code and log tail). Covers authorization, idempotency, and internal mechanism (docker exec). Complete for a single-action tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds no information about input parameters beyond what the schema already provides. The schema has 67% coverage (two of three parameters described), and the slug parameter lacks a description in both schema and 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 the tool triggers a cron job immediately, with concrete use cases and a clear verb + resource. It distinguishes itself from sibling tools like appcrane_list_cron.
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?
Provides explicit use cases ('test daily rebuild without waiting', 'rerun yesterday's failed job'). Does not explicitly compare to alternatives, but the intended context is clear.
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?
The description discloses that validated requests are considered closed and that the tool requires app-admin or AppCrane admin role. Since no annotations are provided, the description adequately covers behavioral traits for a simple state transition 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?
The description is extremely concise: two sentences that cover purpose, lifecycle, examples, and role requirement. No unnecessary words, front-loaded with the core action.
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 tool's simplicity (2 required params, no output schema, no nested objects), the description is complete. It explains the lifecycle, provides usage examples, and specifies role requirements, which is sufficient for an agent to correctly invoke the 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%, so baseline is 3. The description adds that id is the request # column and bucket is the target, which adds minimal meaning beyond what the schema already provides (enum values and 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 moves a request through a lifecycle with specific transitions (triage to in_progress to shipped to validated). It gives concrete examples of when each transition should be used, making the purpose very clear.
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 lists when to use each state transition (e.g., "I'll take #42" for in_progress, after merging PR for shipped, after confirming fix for validated). It does not explicitly mention when not to use this tool or alternatives, but the provided scenarios are sufficient for basic 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?
With no annotations, the description covers key behaviors: approval, role assignment, request completion, validation, and permission requirements. It does not detail side effects or error scenarios, but for a straightforward approval 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 three sentences long, with the first sentence front-loading the purpose. Every sentence adds value: purpose, use case, safety, and output format. No redundant or 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 tool's simplicity (list files), the description covers all essential aspects: what it does, when to use it, safety constraints, and output format. No output schema exists, but the description mentions the return type as text, which is sufficient. The description is complete for effective 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 67% (path and stage have descriptions, slug does not). The description reinforces the path constraint (must start with /app or /data) but does not add much beyond what the schema already provides. For slug, no additional semantics are given, so the parameter description is not significantly enriched.
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 'List' and the resource 'files inside a running app container at a specific path'. It distinguishes this tool from sibling tools like appcrane_cat or appcrane_cp by focusing on listing directory contents. The purpose is 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?
The description gives a specific use case: 'Use to verify what actually got built / what files made it into the deployed image.' It implies when to use this tool, though it does not explicitly mention when not to use it or provide direct comparison to siblings. The context of safe roots and read-only further guides appropriate usage.
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 provided, so description fully bears the burden. It discloses multiple behavioral traits: single hop, no container/GitHub round-trip, no inline size ceiling; exact file path mapping; return of SHA-256 and byte count; assurance that secrets are never returned; and path constraints.
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 paragraph that front-loads the core purpose and quickly adds crucial context. Every sentence provides value, though it is slightly verbose with some redundancy (e.g., path constraints repeated).
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 5 parameters, no output schema, and no annotations, the description covers purpose, usage, behavior, parameter hints, return value, auth, and safety. No major gaps remain; it is fully adequate for an AI agent to select and invoke the tool correctly.
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% (all 5 parameters described in schema). The description adds some context (e.g., 'single hop') but largely reinforces schema details like path rules and encoding. Value added is marginal 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?
The description clearly states the action ('Copy/upload a file') and the target resource ('persistent /data volume on the host'). It distinguishes itself from siblings (e.g., appcrane_push_to_managed_app) by highlighting the lack of size ceiling and direct transfer, and lists aliases.
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 this tool: 'Right tool for multi-MB datasets, large fixtures, or anything where appcrane_push_to_managed_app's tool-arg ceiling would force chunking.' Also specifies prerequisites: 'App-admin or owner of the app required.'
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?
Discloses that secrets are returned decrypted, defaults to sandbox, requires app-admin/AppCrane admin role, and non-admins get permission error. No annotations provided, but description fully covers behavioral 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?
Three sentences, front-loaded with main action, no fluff. 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, the description could specify the return format (e.g., list of key-value pairs). Otherwise covers behavior, role, and error cases well.
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 adequately. The description adds context about stage default but doesn't significantly expand parameter meaning 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 retrieves all secrets (encrypted environment variables) decrypted for an app. It distinguishes from siblings like appcrane_set_secret (modifies) and appcrane_get_app (different resource).
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 says when to use: when user asks about config/secrets or verifying env vars. Provides guidance on default stage and explicitly warns against using production unless user specifies. Also mentions required roles and permission errors.
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 path validation rules, that the container must be running, and that the staged blob is deleted on success. However, it lacks details on error handling or idempotency.
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 paragraph but well-organized: starts with purpose, then usage context, then step-by-step process. 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.
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 doesn't explain return value. It covers prerequisites, path constraints, and deletion behavior. Could mention success/failure indication, but otherwise complete for the tool's complexity.
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% with descriptions for all 4 parameters. The description adds context beyond schema: for 'token' it explains source (returned by POST), for 'dest' it adds validation constraints. This adds value, raising from baseline 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 explicitly states the verb 'Move' and resource 'previously-staged file into a running container at a path under /app or /data'. It distinguishes from sibling appcrane_cp by noting it's for large binaries too big to inline.
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?
Clearly states when to use: for large binaries when they're too big for appcrane_cp. Provides explicit two-step process prerequisites: uploading via POST and requiring the container to be running.
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 discloses that the tool replaces any existing icon, requires app-admin or owner permissions, and mentions a 500 KB size limit. While it doesn't detail side effects or rollback options, the provided information is sufficient for safe usage.
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 (4 sentences) and front-loaded with the main purpose. Every sentence contributes necessary context: usage guidelines, format options, alternative approach, and authorization requirements. No superfluous text.
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 lack of output schema and annotations, the description adequately covers purpose, usage, behavior, and parameters. It does not describe the return value (e.g., success/error), but for a setter tool this is acceptable. Overall, it provides a complete understanding for an agent to use the tool correctly.
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 input schema covers all three parameters (slug, base64, format) with descriptions. The description adds practical value: it clarifies that base64 can include or omit the data URL prefix, specifies the max decoded size, and explains format determines the file extension. This enhances usability 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's purpose: 'Set the tile icon for an app' and specifies where the icon appears. It distinguishes the tool from the alternative of committing a repo icon, making its purpose unambiguous.
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?
The description explicitly explains when to use the tool ('when the icon needs to change without a redeploy, or when the source isn't in the repo') and when not to ('For repo-tracked icons prefer committing public/icon.png to the repo'). This provides clear usage 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 exist, so the description carries full burden. It discloses the scope (pre-container output) and the nature of errors covered. However, it does not mention response format (text/plain) or potential limitations like log truncation, but this is partially covered by the 'tail' parameter.
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 well-structured paragraph. Front-loaded with purpose, then usage context, then parameter alternatives. 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?
Covers the core purpose, distinguishes from siblings, explains parameter options, and provides use-case guidance. Missing details on error handling (e.g., if both deployment_id and slug+env provided) but overall complete for the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema already covers 100% of parameters with descriptions, but the tool's description adds significant context: clarifies the relationship between deployment_id vs slug+env, explains the default for 'tail' (500), and states that stage is required when deployment_id is omitted. This goes 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 reads deploy/build logs from pre-runtime stages (clone, npm install, docker build, health-validate), distinguishing it from sibling appcrane_get_logs which shows runtime logs. The verb 'Read' and resource 'deploy/build log' are 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 Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use this tool (fast deploy failures) versus alternatives (appcrane_get_logs for runtime), and how to specify the deployment via deployment_id or slug+env. Also references prerequisites (deployment_id from other tools).
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, but the description thoroughly covers blocking behavior, terminal states, timeout (default 180s, max 600s), and return object on timeout. Transparent and complete.
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?
Concise, well-structured, front-loaded with essential behavior. Every sentence adds value without verbosity.
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?
Completes the picture for a blocking wait tool: explains return behavior, timeout handling, integration with appcrane_deploy, and no output schema needed because description covers return format. All relevant context included.
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 with descriptions (100% coverage). Description adds context that deployment_id comes from appcrane_deploy but doesn't substantially enhance semantic 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?
The description clearly states the tool blocks until a deployment reaches a terminal state and returns final status. It distinguishes from siblings like appcrane_get_logs (polling) and appcrane_deploy (triggering).
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 says to use after appcrane_deploy instead of polling appcrane_get_logs, describes immediate return if terminal, and explains timeout behavior. Full guidance provided.
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 discloses authentication, batch commit behavior, per-file integrity check, staged upload process, and version-specific changes, ensuring the agent understands operational details.
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?
Well-structured with front-loaded purpose, but includes detailed version notes and examples that make it verbose; still earns its length for a complex tool.
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?
Covers authentication, file types, sizes, integrity, and staged upload; lacks formal return schema but describes response fields (sha256, bytes) and error handling ('fail loudly'). Almost complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Adds significant meaning beyond schema: explains slug resolves to AMC_<slug>, encoding behavior with staged_token, and detailed staged_token workflow. Schema coverage is 75% but description compensates fully.
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?
Explicitly states 'Push a batch of files to a managed app's AMC_<slug> repo' and contrasts with github_push_files, making the tool's purpose and intended use clear.
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 guidance: 'Use this — NOT github_push_files — for managed apps' with rationale, plus prerequisite 'Requires the app to already exist via appcrane_create_managed_app', and instructions for large files versus inline.
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 exist, so description carries full burden. It comprehensively discloses behaviors: owner/admin requirement, visibility enum values, auth_mode details (headless bypasses all forward_auth), auth_bypass_paths header stripping and logging suppression, domain DNS and TLS provisioning, and category constraints. No contradictions with missing annotations.
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 front-loaded with purpose and includes structured parameter details. While verbose, it efficiently packs necessary information without redundancy. Could be slightly trimmed, but the complexity justifies length.
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 6 parameters, no output schema, and no annotations, the description covers all parameter details, ownership constraints, behavioral implications, and security considerations comprehensively. No obvious gaps for the intended functionality.
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% with detailed descriptions, but the description adds significant value beyond schema: explains headless mode use cases, auth_bypass_paths logging suppression and security context, domain requirements, and category ownership constraints. This enriches parameter understanding.
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 sets app's category, visibility, auth_mode, and auth_bypass_paths, distinguishing it from sibling appcrane_update_app for admin-only fields. Verb 'set' and specific resource details provide unambiguous purpose.
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 required roles (owner or global admin), provides guidance on when to use headless mode (telemetry ingest, public webhooks, status pages) vs. auth_bypass_paths, and directs to alternative tool for powerful fields. This offers clear context for appropriate usage.
