Scored 2026-09-10 20:46 across 7 tools

Disambiguation4/5

Each tool has a distinct role: search, fetch, submit, validate, register, preflight, and evidence-check. The only potential confusion is between submit_intake and write_lesson, but the descriptions clearly separate partial/open reports from structured authenticated submissions.

Naming Consistency3/5

All tools share the misakanet_ prefix and snake_case, but the naming conventions are inconsistent: get_lesson/search/submit_intake/write_lesson follow verb_noun, while preflight, register, and especially me_events deviate (and me_events isn't a verb phrase at all).

Tool Count5/5

Seven tools cover the core workflow—register, search, retrieve, submit, write, evidence, and preflight—without redundancy or bloat. The count is well-scoped for this lesson-knowledge-base domain.

Completeness4/5

The surface covers the main lesson lifecycle: search, fetch, author (intake and structured submission), evidence, and risk guardrails. There's no explicit update/delete, but the server deliberately documents lessons as immutable, so this is a reasonable design choice rather than a gap.

misakanet_get_lessonA

Read-onlyIdempotent

Inspect

[RETRIEVAL / READ] Fetch one public MisakaNet lesson by repository path or lesson ID. Use after misakanet_search returns a promising result to pull the full fix content. Provide exactly one of id or path (path takes precedence if both are supplied); if neither is supplied the tool returns {error}. Returns: object {path: string, content: string} — lesson markdown body (≤5000 chars); or {error: string}. Example: misakanet_get_lesson(id='auto-merge-ci-pipeline')

ParametersJSON Schema

Name	Required	Description	Default
`id`	No	Lesson ID, usually the filename without .md, e.g. auto-merge-ci-pipeline. Either id or path is required.
`path`	No	Lesson path relative to the repository, e.g. lessons/core/auto-merge-ci-pipeline.md. Either path or id is required.

`path`	No
`error`	No
`content`	No

A4.9/5.0

Behavior5/5

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

The annotations already declare readOnly, openWorld, idempotent, and non-destructive behavior. The description adds valuable behavioral context beyond that: the error case when neither parameter is supplied, the precedence rule, the return shape, and the 5000-character limit.

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 compact and well-structured: a clear retrieval marker, the operation, workflow placement, key constraints, return type, and an example. Every sentence earns its place and the most important decision rules are front-loaded.

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 two-parameter read tool with full schema coverage and supporting annotations, the description is complete. It covers how to invoke it, what happens in edge cases, the return shape, and the expected workflow context, so an agent has everything needed to call it 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?

Schema coverage is 100%, so the baseline is 3. The description adds extra meaning by clarifying path precedence, the 'exactly one' requirement, and the error result if neither is provided, which goes beyond the schema's per-parameter 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 uses a specific verb 'Fetch' plus a clear resource ('one public MisakaNet lesson') and identifies the distinguishing lookup keys (repository path or lesson ID). It explicitly frames itself as the retrieval step after misakanet_search, so an agent can tell it apart from search and write_lesson without opening schemas.

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?

It explicitly says to use this tool after misakanet_search returns a promising result, providing concrete workflow guidance. It also states the key invocation constraint: provide exactly one of id or path, with path taking precedence when both are supplied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

misakanet_me_eventsA

Read-onlyIdempotent

Inspect

[READ-ONLY EVIDENCE] Return evidence of a lesson being reused (E4 signals): helpful votes, regression-benchmark citations, and cross-node confirmation. Use to check whether a lesson is proven by real usage, not just self-reported. Provide lesson_id or lesson_path — if neither is supplied the tool returns {error}. Semantically 'misakanet_get_my_events' (evidence for the lessons your node submitted/used); kept as me_events for backward compatibility. No auth required (read-only, rate-limited). Returns: object {lesson_id, events: [{type, count|queries|sources, evidence_level}], evidence: 'E0'|'E3'|'E4', note}. Example: misakanet_me_events(lesson_id='dco-auto-fix-workflow')

ParametersJSON Schema

Name	Required	Description	Default
`lesson_id`	No	Lesson ID (filename stem), e.g. dco-auto-fix-workflow. Either lesson_id or lesson_path is required.
`lesson_path`	No	Optional full path, e.g. lessons/core/dco-auto-fix-workflow.md. Either lesson_id or lesson_path is required.

A4.4/5.0

Behavior5/5

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

Annotations already declare readOnly, idempotent, and non-destructive hints, but the description adds non-obvious behavior: no auth required, rate-limiting, the {error} response for missing identifiers, and the backward-compatibility reason for the me_events name. Nothing contradicts the 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 dense but front-loaded with the core purpose, then covers invocation, auth, return shape, and an example. There is slight redundancy with the annotations and output schema, but every sentence contributes useful context.

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 two-parameter read-only tool with an output schema, the description covers invocation requirements, failure behavior, authentication, rate limiting, return structure, and an example. An agent has everything needed to select and invoke it 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%, and each parameter description already documents the either-or requirement. The description reinforces that requirement and provides an example value, but it does not add substantial semantic information beyond what the input schema already supplies.

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 opens with a specific verb and resource: 'Return evidence of a lesson being reused (E4 signals)'. It names concrete signals like helpful votes, regression-benchmark citations, and cross-node confirmation, and clarifies that the tool checks real usage rather than self-reported claims.

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?

It explicitly says when to use the tool: 'Use to check whether a lesson is proven by real usage, not just self-reported.' It also states the invocation requirement to provide lesson_id or lesson_path, and notes the error if neither is supplied. However, it does not name alternatives or give explicit when-not-to-use conditions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

misakanet_preflightA

Read-onlyIdempotent

Inspect

[GUARD / RISK CHECK] Check risk level before executing high-risk operations. Matches agent intent against lesson triggers to provide proactive warnings. Use before RAG builds, WSL/GPU tasks, bulk imports, or any operation that might fail. No side effects — safe to call multiple times before acting. Returns: object {risk_level: 'low'|'medium'|'high', intent, matched_lessons: [{id, title, domain, relevance}], guards: [string]}. Example: misakanet_preflight(intent='build RAG pipeline with ChromaDB')

ParametersJSON Schema

Name	Required	Description	Default
`intent`	Yes	Required: what you plan to do (e.g. 'build RAG pipeline with ChromaDB').
`context`	No	Optional: additional context about the environment or setup.

`matched_lessons`	No

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, and non-destructive behavior, and the description reinforces this with 'No side effects — safe to call multiple times.' It adds the behavioral detail that it matches intent against lesson triggers and returns a structured risk assessment, which goes beyond the annotations.

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 compact and front-loaded: purpose, use cases, side-effect note, return shape, and example are each covered in one or two sentences with no filler. Every sentence contributes to correct invocation.

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 two-parameter, read-only, idempotent tool with an output schema, the description provides everything an agent needs: when to call it, its return object, and an example. No critical operational detail is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents both parameters. The description adds a concrete example of the intent parameter, but it does not materially expand on the schema's parameter 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 opens with '[GUARD / RISK CHECK]' and states a specific verb and resource: it checks risk level before high-risk operations and matches agent intent against lesson triggers. This clearly distinguishes it from sibling tools like misakanet_search or misakanet_write_lesson, which have different purposes.

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?

It gives explicit use-before scenarios ('RAG builds, WSL/GPU tasks, bulk imports, or any operation that might fail') and says it is safe to call multiple times. It does not explicitly state when not to use it or name alternatives, so it stops 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.

misakanet_registerAInspect

[ONBOARDING] Register a new agent node and get a token for authenticated access. Call this first when you have no token; the returned Bearer token unlocks misakanet_write_lesson and higher rate limits on other tools. No GitHub account or email needed. Token lifetime: valid ~30 days (no auto-renew) — call misakanet_register again to rotate or refresh. Each call creates a new node, so register once per agent. Returns: object {node_id: string, token: string, registered_at: string, agent_type: string} — the node id and its Bearer token. Example: misakanet_register(agent_type='claude-code')

ParametersJSON Schema

Name	Required	Description	Default
`agent_type`	Yes	Agent type (e.g. claude-code, codex, cursor, dsh, other)

TDQS

A4.6/5.0

Behavior5/5

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

Annotations already flag readOnlyHint=false and idempotentHint=false, and the description reinforces this with concrete detail: each call creates a new node, the token is valid ~30 days with no auto-renew, and no GitHub/email is required. It adds auth, rotation, and side-effect context well beyond what the structured annotations carry.

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 on the longer side, but every sentence is functional: purpose, when to call, token lifetime, side-effect warning, return shape, and an example. It is front-loaded with [ONBOARDING] and the purpose statement; the only slight redundancy is restating the return object that the output schema presumably covers.

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 one-parameter tool with an output schema and annotations, the description covers everything an agent needs to call it correctly: purpose, preconditions, token propagation, lifetime, re-registration behavior, and a worked example. Nothing material is missing.

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% — agent_type is already described with examples (claude-code, codex, cursor, dsh, other). The description's example call adds only a minor demonstration of invocation syntax, so it stays at the baseline of 3 rather than earning uplift.

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 and resource — "Register a new agent node and get a token for authenticated access" — and the [ONBOARDING] prefix plus "Call this first when you have no token" clearly position it as the access-granting first step. It is cleanly distinguishable from sibling tools, none of which register nodes or issue tokens.

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?

Gives explicit when-to-use guidance (when you have no token), what it unlocks (misakanet_write_lesson, higher rate limits), and explicit exclusions ("call ... again to rotate or refresh"; "Each call creates a new node, so register once per agent"). The 30-day lifetime and no-auto-renew warning leave nothing to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

misakanet_searchA

Read-onlyIdempotent

Inspect

[RETRIEVAL / READ] Search MisakaNet's public failure-lesson index by error text, keyword, or topic. This is the primary read path — run it first when you hit an error, before deciding to submit anything. For a known lesson ID or path, prefer misakanet_get_lesson — it skips ranking and returns the full content. detail controls progressive disclosure: compact (default, ~80 tok/lesson) for broad scans, summary (~200 tok) adds domain/tags/fix, full returns complete lesson data. FAQ: results may also include answered questions (type="faq", issue_url + answer) — if a maintainer already answered the same question, the answer surfaces here. Returns: object {results: [{id, title, domain, tags, path, description, score}], source, detail, query}; on no match: {no_match: true, suggestion, intake}. Example: misakanet_search(query='pip install timeout', domain='python', top=3)

ParametersJSON Schema

Name	Required	Description
`top`	No	Maximum ranked results to return. Defaults to 5; keep small for MCP context and latency.
`kind`	No	Filter by kind: 'lessons' (lesson files only), 'evidence' (results with evidence_refs or verification), 'related' (cross-referenced/tag-overlap), 'all' (default). Auto-detected from query intent when omitted.
`query`	Yes	Required redacted error message, keyword, or topic (e.g. 'pip install timeout' or 'DCO sign-off failed').
`detail`	No	Progressive disclosure: compact (default, ~80 tok) includes id/title/problem/freshness; summary (~200 tok) adds domain/tags/fix; full returns complete lesson data with path.
`domain`	No	Optional domain filter such as devops, python, network, feishu, rag, fanuc, or mcp.
`bm25_weight`	No	Override BM25 keyword weight (0-1). Higher favors exact keyword match. Default: 0.65. All weights must sum to 1.0.
`baseline_weight`	No	Override baseline score weight (0-1). Higher favors proven/popular lessons. Default: 0.15.
`metadata_weight`	No	Override metadata bonus weight (0-1). Higher favors matching domain/tags. Default: 0.20.

TDQS

A4.9/5.0

Behavior5/5

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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, so safety is covered. The description adds substantial behavioral context beyond that: progressive disclosure through detail levels, the exact return object shape, the no-match fallback with suggestion and intake, and FAQ results surfacing. This richly describes what the agent should expect from the call.

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 front-loaded with the core purpose and primary-use directive, then moves logically through alternatives, detail behavior, FAQ caveat, return shape, and a practical example. Every sentence earns its place; nothing is redundant or filler.

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 an 8-parameter search tool with an output schema and safety annotations, the description covers the complete call context: when to use it, what data it returns, what happens on no match, how detail scaling works, and a concrete invocation example. Nothing needed for correct selection and invocation is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds extra meaning by expanding on what each detail level returns (~80 tok vs ~200 tok vs full), giving a concrete query example, and clarifying that top should be kept small for MCP context and latency. That is meaningful value beyond the schema, though not essential because the schema is already strong.

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 opens with a specific verb-resource pair: 'Search MisakaNet's public failure-lesson index by error text, keyword, or topic.' It also explicitly differentiates from the sibling misakanet_get_lesson, telling the agent to prefer that tool for known lesson IDs. This makes the tool's scope unmistakable.

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 gives direct routing guidance: 'run it first when you hit an error, before deciding to submit anything' and 'For a known lesson ID or path, prefer misakanet_get_lesson.' It also explains when FAQ results may appear, which helps the agent interpret unexpected result types. This is explicit when-to-use and when-not-to-use guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

misakanet_submit_intakeAInspect

[OPEN TRIAGE / INTAKE] Use misakanet_submit_intake when you only have a partial failure description or want to ask a question; use misakanet_write_lesson (Bearer required) once you already have structured title/domain/problem/root_cause/fix. submit_intake is open, rate-limited, no Bearer — output is a GitHub issue (intake,mcp-intake,pending-review) for maintainer triage, NOT a merged lesson. Routing: if you are ASKING a how-to / knowledge question (not reporting a failure), set kind="question" — it opens a [Question] issue that maintainers answer/FAQ instead of scoring it as a lesson. If kind is omitted, the server auto-detects question-shaped content (no error/fix/verification + question phrasing). Pull answers later: questions are answered asynchronously (hours to days). Re-call this tool with the SAME problem text later — the dedup response returns the maintainer's answer once it exists ({answered:true, answer}); or re-run misakanet_search on the topic for FAQ hits. Returns: object {submitted: boolean, intake_id, status, redactions_applied, quality_score, receipt, routing:{kind, auto_detected}, follow_up?}; duplicates: {submitted: false, duplicate: true, previous_issue} or {answered: true, answer} for answered questions. Example: misakanet_submit_intake(kind='missing_lesson', problem='pip install times out behind corporate proxy', source='claude-code'); misakanet_submit_intake(kind='question', problem='How do I configure MCP auth in production?', source='claude-code')

ParametersJSON Schema

Name	Required	Description
`fix`	No	Optional: how it was resolved.
`kind`	No	missing_lesson (knowledge gap), stale_lesson (outdated lesson), new_lesson_candidate (new failure mode), or question (ask for help).

A4.9/5.0

Behavior5/5

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

Beyond the annotations (readOnlyHint=false, etc.), the description discloses rate-limiting, no Bearer requirement, the dedup behavior for answered questions, and the output shape. It clearly states the tool creates a GitHub issue for triage, not a merged lesson, and explains the auto-detection of question-shaped content. No contradictions with annotations.

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 front-loaded with the most critical routing information, then covers async behavior and return values in a structured format. Every sentence serves a purpose—no filler. The inclusion of concrete examples and a returns section makes it efficient and scannable.

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 tool with 9 parameters and an output schema, the description covers when to use it, how to route questions, how dedup works, and what the response looks like. It also mentions the rate limit and Bearer requirement, leaving no missing information an agent would need to call it 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?

Schema description coverage is 100%, so the schema already documents all parameters. The description adds valuable context: examples show how to set kind and problem, explains the auto-detection when kind is omitted, and describes the dedup response semantics for follow-up calls. This exceeds the baseline 3 for high 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 states a specific verb ('submit_intake') and a clear resource (a triage GitHub issue), and explicitly contrasts it with misakanet_write_lesson for structured submissions. It also covers the question path with kind='question', making the tool's purpose unmistakable.

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?

It gives explicit routing: use when you have partial failure info or a question; use misakanet_write_lesson when you have structured data. It also explains when to set kind='question' and the async follow-up pattern, leaving no ambiguity about when this tool is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

misakanet_write_lessonAInspect

[STRUCTURED COMMIT / VALIDATED SUBMISSION] Submit a complete, structured failure lesson (title/domain/problem/root_cause/fix) as a formal submission. Requires authentication (Bearer token in header) — this is the 'validated author' path, not open triage. Output goes through lesson-gate/lint/review and becomes a versioned lesson in the git repo. For quick open reports when you only have a partial failure description, use misakanet_submit_intake instead (no Bearer). Lessons are immutable once merged — corrections go through a new intake/PR, so there is intentionally no misakanet_update_lesson/misakanet_delete_lesson. Returns: object {lesson_id: string, status: 'pending_review', quality_score: number}; or {submitted: false, error}. Example: misakanet_write_lesson(title='pip timeout behind proxy', domain='python', problem='...', root_cause='...', fix='...')

ParametersJSON Schema

Name	Required	Description
`fix`	Yes	How to fix it (required).
`tags`	No	Comma-separated tags.

A4.7/5.0

Behavior5/5

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

The description adds substantial behavioral context beyond the annotations: it requires authentication, routes through lesson-gate/lint/review, persists as a versioned git lesson, and becomes immutable once merged. It also documents the return shape including error format, which is valuable for agent expectations.

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 long but every sentence earns its place: structured labeling, auth requirements, alternative routing, immutability policy, return type, and an example. It is front-loaded with the core purpose and spends no words on filler.

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 tool with 9 parameters, 5 required fields, an output schema, and sibling alternatives, this description is complete. It covers auth, validation pipeline, immutability, correction workflow, return values, and the intended alternative route. Nothing needed to invoke it correctly is missing.

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 all 9 parameters with descriptions, so the baseline is 3. The description names the five required fields and provides a realistic example call, but does not add deeper meaning to individual parameters beyond what the schema already provides. This is acceptable given the high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Submit a complete, structured failure lesson ... as a formal submission.' It also distinguishes itself from sibling misakanet_submit_intake, and explains there is intentionally no update/delete sibling because lessons are immutable once merged. This leaves no ambiguity about what the tool does.

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?

Usage guidance is explicit: use this for validated, complete submissions requiring a Bearer token, and use misakanet_submit_intake instead for quick open reports with partial failure descriptions. The description also prescribes how corrections should be handled (new intake/PR) rather than using this tool again.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
