Replace transcript-style agent examples with prose trigger descriptions

ce721c1f1d Replace transcript-style agent examples with prose trigger descriptions
Several agent files used <example> blocks containing user: "..." /
assistant: "..." turn markers, embedded as \n-escaped strings inside
the YAML frontmatter description: field. Replace those with flat prose
trigger descriptions in description: and a 'When to invoke' section
in the agent body containing prose-bullet scenarios.

Affected files:
- 5 agent definitions:
  - plugins/hookify/agents/conversation-analyzer.md
  - plugins/pr-review-toolkit/agents/code-reviewer.md
  - plugins/pr-review-toolkit/agents/pr-test-analyzer.md
  - plugins/pr-review-toolkit/agents/type-design-analyzer.md
  - plugins/pr-review-toolkit/agents/comment-analyzer.md
- 5 agent-development skill files updated to teach the new format:
  - plugins/plugin-dev/skills/agent-development/SKILL.md
  - .../references/triggering-examples.md
  - .../references/agent-creation-system-prompt.md
  - .../examples/complete-agent-examples.md
  - .../examples/agent-creation-prompt.md

Routing is unaffected: each description: still names the trigger
surface in plain English.

You are a conversation analysis specialist that identifies problematic behaviors in Claude Code sessions that could be prevented with hooks.
## When to invoke
Two representative scenarios:
- **Scenario A — `/hookify` invoked with no arguments.** Treat the bare `/hookify` invocation as a request to analyze the current conversation and surface unwanted behaviors. Respond by saying you'll analyze the conversation, then run the analysis described below.
- **Scenario B — User asks to learn from recent frustrations.** When the user asks (in their own words) to look back over the conversation and create hooks for mistakes that were made, run the same analysis and propose hook rules for the issues found.
**Your Core Responsibilities:**
1. Read and analyze user messages to find frustration signals
2. Identify specific tool usage patterns that caused issues

# Agent Creation System Prompt
This is the exact system prompt used by Claude Code's agent generation feature, refined through extensive production use.

@@ -36,32 +37,25 @@ When a user describes what they want an agent to do, you will:
- Is memorable and easy to type
- Avoids generic terms like "helper" or "assistant"
6. **Example agent descriptions**:
- In the 'whenToUse' field of the JSON object, you should include examples of when this agent should be used.
- Examples should be of the form:
<example>
Context: The user is creating a code-review agent that should be called after a logical chunk of code is written.
user: "Please write a function that checks if a number is prime"
assistant: "Here is the relevant function: "
<function call omitted for brevity only for this example>
<commentary>
Since a logical chunk of code was written and the task was completed, now use the code-review agent to review the code.
</commentary>
assistant: "Now let me use the code-reviewer agent to review the code"
</example>
- If the user mentioned or implied that the agent should be used proactively, you should include examples of this.
- NOTE: Ensure that in the examples, you are making the assistant use the Agent tool and not simply respond directly to the task.
6. **Trigger description format**:
- The 'whenToUse' field is flat prose on a single line.
- Format: "Use this agent when [conditions]. Typical triggers include [scenario 1], [scenario 2], and [scenario 3]. See \"When to invoke\" in the agent body for worked scenarios."
- Detailed scenarios go in the system prompt under a "When to invoke" heading, as a bullet list of prose descriptions. Each bullet starts with a bold short scenario name followed by a prose description of the situation and what the agent should do.
- Example bullets:
- "**Proactive review after new code.** The assistant has just written a function in response to a user request. Run a self-review for quality and security before declaring the task done."
- "**Explicit review request.** The user asks for the recent changes to be reviewed. Run a thorough review and report findings."
- Cover both proactive and reactive triggers when applicable. Do NOT use quoted user utterances at the start of sentences — describe the *situation* the user is in, not the literal phrase they say.
Your output must be a valid JSON object with exactly these fields:
{
"identifier": "A unique, descriptive identifier using lowercase letters, numbers, and hyphens (e.g., 'code-reviewer', 'api-docs-writer', 'test-generator')",
"whenToUse": "A precise, actionable description starting with 'Use this agent when...' that clearly defines the triggering conditions and use cases. Ensure you include examples as described above.",
"systemPrompt": "The complete system prompt that will govern the agent's behavior, written in second person ('You are...', 'You will...') and structured for maximum clarity and effectiveness"
"whenToUse": "A precise, actionable description starting with 'Use this agent when...' that clearly defines the triggering conditions and use cases. Flat prose only. End with a pointer to the 'When to invoke' section in the agent body.",
"systemPrompt": "The complete system prompt that will govern the agent's behavior, written in second person ('You are...', 'You will...'). Begins with a 'When to invoke' section (2-4 prose bullets) and follows with persona, responsibilities, process, output format, and edge cases."
}
Key principles for your system prompts:
- Be specific rather than generic - avoid vague instructions
- Include concrete examples when they would clarify behavior
- Include concrete examples when they would clarify behavior (as prose)
- Balance comprehensiveness with clarity - every instruction should add value
- Ensure the agent has enough context to handle variations of the core task
- Make the agent proactive in seeking clarification when needed

# Agent Triggering Examples: Best Practices
# Agent Triggering: Best Practices
Complete guide to writing effective `<example>` blocks in agent descriptions for reliable triggering.
Complete guide to writing trigger descriptions that cause an agent to be dispatched reliably.
## Example Block Format
## Where trigger descriptions live
The standard format for triggering examples:
An agent file has two places that talk about triggering:
1. **`description:` field in YAML frontmatter.** Loaded into context whenever the agent is registered, used by the harness to decide when to dispatch. Keep it flat prose.
2. **A "When to invoke" section in the agent body.** Loaded only when the agent is actually invoked. This is where worked scenarios live, as a bullet list of prose descriptions.
## Format
### `description:` field
```
description: Use this agent when [conditions]. Typical triggers include [scenario 1 phrased as a prose noun phrase], [scenario 2], and [scenario 3]. See "When to invoke" in the agent body for worked scenarios.
```
Rules:
- Single line of flat prose within the YAML scalar.
- Name 2-4 trigger scenarios as noun phrases.
- End with the pointer to the body's "When to invoke" section.
### "When to invoke" body section
```markdown
<example>
Context: [Describe the situation - what led to this interaction]
user: "[Exact user message or request]"
assistant: "[How Claude should respond before triggering]"
<commentary>
[Explanation of why this agent should be triggered in this scenario]
</commentary>
assistant: "[How Claude triggers the agent - usually 'I'll use the [agent-name] agent...']"
</example>
## When to invoke
[Two to four representative scenarios as prose bullets. Each describes the situation
in third person and what the agent should do.]
- **[Short scenario name].** [What the situation looks like — what just happened or what
the user is asking for — and what the agent should do in response.]
- **[Short scenario name].** [Same.]
```
## Anatomy of a Good Example
## Anatomy of a good scenario
### Context
### Scenario name (the bold lead)
**Purpose:** Set the scene - what happened before the user's message
**Purpose:** A short noun phrase identifying the situation type.
**Good contexts:**
```
Context: User just implemented a new authentication feature
Context: User has created a PR and wants it reviewed
Context: User is debugging a test failure
Context: After writing several functions without documentation
**Good names:**
- *User-requested review after a feature lands.*
- *Proactive review of newly-written code.*
- *Pre-PR sanity check.*
- *PR updated with new logic.*
**Bad names:**
- *Normal usage.* (not specific)
- *User needs help.* (vague)
### Scenario body (after the lead)
**Purpose:** Describe what happens and what the agent should do — in prose, third person, no quoted utterances.
**Good:**
> The user has just implemented a feature (often spanning several files) and asks whether everything looks good. Run a review of the recent diff and report findings.
**Bad (transcript shape — do not use):**
> ```
> user: "Can you check if everything looks good?"
> assistant: "I'll use the reviewer agent..."
> ```
The bad version mixes a turn-marker shape into the agent file. Keep scenarios as situation descriptions in prose.
## Trigger types to cover
Aim for 2-4 scenarios that span these axes:
### Explicit request
The user directly asks for what the agent does.
- *User-requested security check.* The user explicitly asks for a security review of recent code.
### Proactive triggering
The assistant invokes the agent without an explicit ask, after relevant work.
- *Proactive review after writing database code.* The assistant has just authored database access code and should check for SQL injection and other database-layer risks before declaring the task done.
### Implicit request
The user implies need without naming the agent.
- *Code-clarity complaint.* The user describes existing code as confusing or hard to follow. Treat as a request to refactor for readability.
### Tool-usage pattern
The agent should follow a particular tool-use pattern.
- *Post-test-edit verification.* The assistant has just made multiple edits to test files. Verify the edited tests still meet quality and coverage standards before continuing.
## Phrasing variation
If the same intent is commonly phrased multiple ways, mention that in prose:
> **Pre-PR sanity check.** The user signals (in any phrasing — "ready to open a PR", "I think we're done here", "let's ship this") that they're about to open a pull request.
Don't write three near-duplicate scenarios that differ only in the literal phrase — collapse them into one prose scenario that names the variation.
## How many scenarios?
- **Minimum: 2.** Usually one explicit + one proactive.
- **Recommended: 3-4.** Explicit, proactive, and one implicit or edge case.
- **Maximum: 5.** More than that bloats the body without adding routing signal.
## Worked example
### Prose triggers in `description:`
```yaml
description: Use this agent when you need to review code. Typical triggers include user-requested review after a feature lands, proactive review of freshly-written code, and a pre-PR sanity check. See "When to invoke" in the agent body for worked scenarios.
```
**Bad contexts:**
```
Context: User needs help (too vague)
Context: Normal usage (not specific)
```
### User Message
**Purpose:** Show the exact phrasing that should trigger the agent
**Good user messages:**
```
user: "I've added the OAuth flow, can you check it?"
user: "Review PR #123"
user: "Why is this test failing?"
user: "Add docs for these functions"
```
**Vary the phrasing:**
Include multiple examples with different phrasings for the same intent:
```
Example 1: user: "Review my code"
Example 2: user: "Can you check this implementation?"
Example 3: user: "Look over my changes"
```
### Assistant Response (Before Triggering)
**Purpose:** Show what Claude says before launching the agent
**Good responses:**
```
assistant: "I'll analyze your OAuth implementation."
assistant: "Let me review that PR for you."
assistant: "I'll investigate the test failure."
```
**Proactive example:**
```
assistant: "Great! Now let me review the code quality."
<commentary>
Code was just written, proactively trigger review agent.
</commentary>
```
### Commentary
**Purpose:** Explain the reasoning - WHY this agent should trigger
**Good commentary:**
```
<commentary>
User explicitly requested code review, trigger the code-reviewer agent.
</commentary>
<commentary>
After code implementation, proactively use review agent to check quality.
</commentary>
<commentary>
PR analysis request matches pr-analyzer agent's expertise.
</commentary>
```
**Include decision logic:**
```
<commentary>
User wrote tests (Test tool used). The test-analyzer agent should check
test quality and coverage before continuing.
</commentary>
```
### Assistant Response (Triggering)
**Purpose:** Show how Claude invokes the agent
**Standard pattern:**
```
assistant: "I'll use the [agent-name] agent to [what it will do]."
```
**Examples:**
```
assistant: "I'll use the code-reviewer agent to analyze the changes."
assistant: "Let me use the test-generator agent to create comprehensive tests."
assistant: "I'll use the security-analyzer agent to check for vulnerabilities."
```
## Example Types
### Type 1: Explicit Request
User directly asks for what the agent does:
### Scenarios as situation descriptions in the body
```markdown
<example>
Context: User explicitly requests security analysis
user: "Check my code for security vulnerabilities"
assistant: "I'll use the security-analyzer agent to perform a thorough security review."
<commentary>
Direct security analysis request triggers the security-analyzer agent.
</commentary>
</example>
## When to invoke
- **User-requested review.** The user asks for a review of recent changes (any phrasing). Run a review of the unstaged diff.
```
### Type 2: Proactive Triggering
Agent triggers after relevant work without explicit request:
### Trigger condition only — output format goes elsewhere
```markdown
<example>
Context: User just implemented database queries
user: "I've added the user search functionality"
assistant: "Great! Let me review it for security."
<commentary>
Database code written. Proactively trigger security-analyzer to check
for SQL injection and other database security issues.
</commentary>
assistant: "I'll use the security-analyzer agent to check the database code."
</example>
- **Review.** The user asks for a review. Run the review and report findings as specified in the Output Format section.
```
### Type 3: Implicit Request
## Template library
User implies need without stating it directly:
### Code review agent
```yaml
description: Use this agent when you need to review code for adherence to project guidelines and best practices. Typical triggers include the user asking for a review of a feature they just implemented, proactive review of newly-written code before declaring a task done, and a pre-PR sanity check. See "When to invoke" in the agent body.
```
```markdown
<example>
Context: User mentions code is hard to understand
user: "This code is confusing and hard to follow"
assistant: "I can help improve the code clarity."
<commentary>
User indicates complexity issues. Trigger code-simplifier agent to refactor
for better readability.
</commentary>
assistant: "I'll use the code-simplifier agent to suggest improvements."
</example>
## When to invoke
- **User-requested review after a feature lands.** The user has implemented a feature and asks whether the result looks good. Review the recent diff and report findings.
- **Proactive review of newly-written code.** The assistant has just authored new code in response to a user request. Run a self-review before declaring the task done.
- **Pre-PR sanity check.** The user signals readiness to open a pull request. Review the full diff first.
```
### Type 4: Tool Usage Pattern
### Test generation agent
Agent triggers based on prior tool usage:
```yaml
description: Use this agent when you need to generate tests for code that lacks them. Typical triggers include the user explicitly asking for tests for a function or module, and the assistant proactively generating tests after writing new code that has no test coverage. See "When to invoke" in the agent body.
```
```markdown
<example>
Context: User made multiple edits to test files
user: "I've updated all the tests"
assistant: "Great! Let me verify test quality."
<commentary>
Multiple Edit tools used on test files. Proactively trigger test-quality-analyzer
to ensure tests follow best practices.
</commentary>
assistant: "I'll use the test-quality-analyzer agent to review the tests."
</example>
## When to invoke
- **Explicit test request.** The user asks for tests covering a specific function, module, or feature. Generate a comprehensive test suite.
- **Proactive coverage after new code.** The assistant has just written new code with no accompanying tests. Generate tests before declaring the task done.
```
## Multiple Examples Strategy
### Documentation agent
### Cover Different Phrasings
```yaml
description: Use this agent when you need to write or improve documentation for code, especially APIs. Typical triggers include the user asking for docs on a specific function or endpoint, and proactive documentation generation after the assistant adds new API surface. See "When to invoke" in the agent body.
```
```markdown
<example>
user: "Review my code"
[...]
</example>
## When to invoke
<example>
user: "Can you check my implementation?"
[...]
</example>
<example>
user: "Look over these changes"
[...]
</example>
- **Explicit doc request.** The user asks for documentation for a specific surface (function, endpoint, module).
- **Proactive docs for new API surface.** The assistant has just added new API endpoints or public functions without docstrings.
```
### Cover Proactive and Reactive
### Validation agent
```yaml
description: Use this agent when you need to validate code before commit or merge. Typical triggers include the user signaling readiness to commit, and an explicit validation request. See "When to invoke" in the agent body.
```
```markdown
<example>
Context: User explicitly requests review
user: "Review my code for issues"
[...]
</example>
## When to invoke
<example>
Context: After user writes code
user: "I've implemented the feature"
assistant: "Great! Now let me review it."
<commentary>
Code written, proactively review.
</commentary>
[...]
</example>
- **Pre-commit validation.** The user signals readiness to commit. Run validation first and surface any issues.
- **Explicit validation request.** The user asks for the code to be validated.
```
### Cover Edge Cases
## Debugging triggering issues
```markdown
<example>
Context: Typical usage
user: "Check my PR"
[...]
</example>
### Agent not triggering
<example>
Context: Large PR that needs thorough analysis
user: "This is a big PR, can you do a deep review?"
[...]
<commentary>
Large PR mentioned, use thorough analysis mode.
</commentary>
</example>
```
Check:
1. The `description:` prose names the right trigger scenarios.
2. The scenarios in the body cover the actual phrasings the user uses.
3. There isn't a more-specific competing agent winning the routing decision.
## Common Mistakes
Fix: add or expand scenarios in the body, and tighten the prose summary in `description:`.
### ❌ Missing Context
### Agent triggers too often
```markdown
<example>
user: "Review my code"
assistant: "I'll use the code-reviewer agent."
</example>
```
Check:
1. The trigger scenarios are too generic or overlap with other agents.
2. The `description:` doesn't say when NOT to use the agent.
**Why bad:** No context about what led to this request.
Fix: narrow the scenarios; add a "Do not invoke when..." line to `description:` if needed.
### ✅ With Context
### Agent triggers in the wrong scenarios
```markdown
<example>
Context: User just finished implementing authentication
user: "Review my code"
assistant: "I'll use the code-reviewer agent to analyze the auth implementation."
<commentary>
Auth code written, review for security and best practices.
</commentary>
</example>
```
Check:
1. Whether the scenarios in the body match the agent's actual capabilities.
### ❌ No Commentary
Fix: rewrite scenarios to match what the agent actually does.
```markdown
<example>
Context: User requests review
user: "Check my changes"
assistant: "I'll use the reviewer agent."
</example>
```
## Best practices summary
**Why bad:** Doesn't explain WHY agent triggers.
### ✅ With Commentary
```markdown
<example>
Context: User requests review after making changes
user: "Check my changes"
assistant: "I'll use the code-reviewer agent to analyze the modifications."
<commentary>
Code review request triggers agent to check quality, security, and adherence to standards.
</commentary>
</example>
```
### ❌ Agent Responds Directly
```markdown
<example>
user: "Review my code"
assistant: "I found the following issues: [lists issues]"
</example>
```
**Why bad:** Shows agent's output, not triggering.
### ✅ Shows Triggering
```markdown
<example>
user: "Review my code"
assistant: "I'll use the code-reviewer agent to perform the review."
<commentary>
Review request triggers the agent.
</commentary>
</example>
```
## How Many Examples?
### Minimum: 2 Examples
Cover at least:
1. Explicit request
2. One variation or proactive trigger
### Recommended: 3-4 Examples
Cover:
1. Explicit request (direct ask)
2. Implicit request (user implies need)
3. Proactive trigger (after relevant work)
4. Edge case or specific scenario
### Maximum: 6 Examples
More than 6 makes description too long. Focus on most important scenarios.
## Template Library
### Code Review Agent
```markdown
<example>
Context: User just implemented a new feature
user: "I've added the user registration feature"
assistant: "Great! Let me review the code quality."
<commentary>
Code written, proactively trigger code-reviewer agent.
</commentary>
assistant: "I'll use the code-reviewer agent to analyze the implementation."
</example>
<example>
Context: User explicitly requests review
user: "Can you review my changes for issues?"
assistant: "I'll use the code-reviewer agent to perform a thorough review."
<commentary>
Explicit review request triggers the agent.
</commentary>
</example>
```
### Test Generation Agent
```markdown
<example>
Context: User implemented functions without tests
user: "I've added the data processing functions"
assistant: "Great! Let me generate tests for these."
<commentary>
New code without tests, proactively trigger test-generator agent.
</commentary>
assistant: "I'll use the test-generator agent to create comprehensive tests."
</example>
<example>
Context: User explicitly asks for tests
user: "Generate tests for my code"
assistant: "I'll use the test-generator agent to create a complete test suite."
<commentary>
Direct test generation request triggers the agent.
</commentary>
</example>
```
### Documentation Agent
```markdown
<example>
Context: User added new API endpoints
user: "I've implemented the REST API endpoints"
assistant: "I'll document these endpoints."
<commentary>
New API code, proactively generate documentation.
</commentary>
assistant: "I'll use the api-docs-writer agent to create comprehensive documentation."
</example>
<example>
Context: User requests documentation
user: "Write docs for this API"
assistant: "I'll use the api-docs-writer agent to generate clear documentation."
<commentary>
Documentation request triggers the agent.
</commentary>
</example>
```
### Validation Agent
```markdown
<example>
Context: User ready to commit changes
user: "I'm ready to commit this code"
assistant: "Let me validate it first."
<commentary>
Before commit, proactively validate with validation-agent.
</commentary>
assistant: "I'll use the code-validator agent to check for issues."
</example>
<example>
Context: User asks for validation
user: "Validate my implementation"
assistant: "I'll use the code-validator agent to verify correctness."
<commentary>
Explicit validation request triggers the agent.
</commentary>
</example>
```
## Debugging Triggering Issues
### Agent Not Triggering
**Check:**
1. Examples include relevant keywords from user message
2. Context matches actual usage scenarios
3. Commentary explains triggering logic clearly
4. Assistant shows use of Agent tool in examples
**Fix:**
Add more examples covering different phrasings.
### Agent Triggers Too Often
**Check:**
1. Examples are too broad or generic
2. Triggering conditions overlap with other agents
3. Commentary doesn't distinguish when NOT to use
**Fix:**
Make examples more specific, add negative examples.
### Agent Triggers in Wrong Scenarios
**Check:**
1. Examples don't match actual intended use
2. Commentary suggests inappropriate triggering
**Fix:**
Revise examples to show only correct triggering scenarios.
## Best Practices Summary
**DO:**
- Include 2-4 concrete, specific examples
- Show both explicit and proactive triggering
- Provide clear context for each example
- Explain reasoning in commentary
- Vary user message phrasing
- Show Claude using Agent tool
**DON'T:**
- Use generic, vague examples
- Omit context or commentary
- Show only one type of triggering
- Skip the agent invocation step
- Make examples too similar
- Forget to explain why agent triggers
- Keep `description:` as flat prose with a short summary of trigger scenarios
- Put detailed scenarios in a "When to invoke" body section, as prose bullets
- Cover both explicit and proactive triggering
- Describe situations the agent should respond to
- Mention phrasing variation in prose ("any phrasing — 'ready to ship', 'looks done'") rather than via multiple near-duplicate scenarios
- Keep trigger scenarios separate from output format
## Conclusion
Well-crafted examples are crucial for reliable agent triggering. Invest time in creating diverse, specific examples that clearly demonstrate when and why the agent should be used.
Reliable triggering comes from prose descriptions of the situations an agent should respond to.

description: Use this agent when you need to review code for adherence to project guidelines, style guides, and best practices. This agent should be used proactively after writing or modifying code, especially before committing changes or creating pull requests. It will check for style violations, potential issues, and ensure code follows the established patterns in CLAUDE.md. Also the agent needs to know which files to focus on for the review. In most cases this will be recently completed work which is unstaged in git (can be retrieved by running git diff). However there can be cases where this is different, make sure to specify this as the agent input when calling the agent. Typical triggers include the user asking for a review of a feature they just implemented, the assistant proactively reviewing its own newly-written code before declaring a task done, and a final pre-PR check before opening a pull request.

You are an expert code reviewer specializing in modern software development across multiple languages and frameworks. Your primary responsibility is to review code against project guidelines in CLAUDE.md with high precision to minimize false positives.
## When to invoke
Three representative scenarios:
- **User-requested review after a feature lands.** The user has just implemented a feature (often spanning several files) and asks whether everything looks good. Run a review of the recent diff and report findings.
- **Proactive review of newly-written code.** The assistant has just written new code (e.g. a utility function the user requested) and wants to catch issues before declaring the task done. Spawn this agent on the freshly written files.
- **Pre-PR sanity check.** The user signals they're ready to open a pull request. Run a review of the full diff first to avoid round-trips on the PR itself.
## Review Scope
By default, review unstaged changes from `git diff`. The user may specify different files or scope to review.

You are a meticulous code comment analyzer with deep expertise in technical documentation and long-term code maintainability. You approach every comment with healthy skepticism, understanding that inaccurate or outdated comments create technical debt that compounds over time.
## When to invoke
Three representative scenarios:
- **User-requested check on freshly-added docs.** The user has just added documentation comments to a set of functions and wants them verified for accuracy against the actual code.
- **Proactive check after generating documentation.** The assistant has just authored detailed documentation (e.g. for a complex authentication handler) and should verify the comments are accurate and helpful before considering the task done.
- **Pre-PR sweep for comment changes.** Before opening a pull request, review every comment that was added or modified across the diff and flag anything inaccurate or likely to rot.
Your primary mission is to protect codebases from comment rot by ensuring every comment adds genuine value and remains accurate as code evolves. You analyze comments through the lens of a developer encountering the code months or years later, potentially without context about the original implementation.
When analyzing comments, you will:

You are an expert test coverage analyst specializing in pull request review. Your primary responsibility is to ensure that PRs have adequate test coverage for critical functionality without being overly pedantic about 100% coverage.
## When to invoke
Three representative scenarios:
- **Fresh PR, thoroughness check.** The user has just opened a PR with new functionality and wants to know whether the tests cover it adequately. Analyze the diff and report critical gaps.
- **PR updated with new logic.** A PR has been pushed with new validation, parsing, or business logic. Check whether the existing tests have been extended to cover the new branches and edge cases.
- **Pre-ready double-check.** Before marking a PR ready for review, run a final pass over the test coverage and surface any remaining gaps.
**Your Core Responsibilities:**
1. **Analyze Test Coverage Quality**: Focus on behavioral coverage rather than line coverage. Identify critical code paths, edge cases, and error conditions that must be tested to prevent regressions.

You are a type design expert with extensive experience in large-scale software architecture. Your specialty is analyzing and improving type designs to ensure they have strong, clearly expressed, and well-encapsulated invariants.
## When to invoke
Two representative scenarios:
- **New type introduced.** The user has just authored a new type (e.g. a domain model handling authentication and permissions) and wants assurance that its invariants and encapsulation are well-designed. Review the type and rate it on the four axes.
- **PR adding several new types.** The user is preparing a PR that introduces multiple new data model types. Review every newly-added type in the diff for design quality.
**Your Core Mission:**
You evaluate type designs with a critical eye toward invariant strength, encapsulation quality, and practical usefulness. You believe that well-designed types are the foundation of maintainable, bug-resistant software systems.
