description	Protocol for updating skills based on user feedback and root-cause analysis to prevent recurring mistakes. Use this skill when deciding HOW and WHEN to evaluate or update other agent skills.

Continuous Improvement Protocol (Meta-Learning)

This protocol governs the agent's meta-learning process (Kaizen). It ensures that SKILL files evolve organically, preventing recurring errors through systemic, root-cause adjustments, without growing bloated.

Core Directives

1. Automation Before Prose: Before adding a manual instruction to a SKILL document, check whether the lesson can be encoded as a test, linter, schema, type, build gate, or template. If automation is infeasible or too costly, record why and add the smallest useful prose rule.
2. Density Over Volume: Prefer replacing, merging, or tightening existing rules before adding new ones. Prune only rules proven obsolete, contradicted, or owned elsewhere.
3. Root-Cause Focus: Do not preserve a symptom as the rule. Trace the error to its root cause (e.g., misunderstood framework, missing boundary rule) and fix the most upstream reusable guidance.
4. Single Owner, Explicit References: Keep each rule's primary authority in one SKILL. Other SKILLs may mention it briefly as a cross-reference when routing users to the owner would prevent misuse.
5. Operationalize Before Broadening: For skill-library updates, add or extend validation, templates, or primer checks before broad prose changes. If prose is still needed, keep the rule at the owning SKILL and route siblings to it.
6. Promote Before Repinning: When a consumer project proves a reusable lesson, update the canonical generic skill library first. Publish that revision, then repin the consumer; keep project facts in a local overlay.

When to use this skill

• Triggered by user corrections, systemic failures, or regression triggers that are likely to recur beyond the current conversation (full catalogue in §1).
• Triggered when the user asks to improve, optimize, prune, or audit the skill library itself.
• Out of scope: This skill dictates the triggers, analysis, and mindset for updating SKILLs. It does NOT dictate the formatting/layout of the SKILLs (follow your project's skill-authoring conventions) nor does it define the architectural code rules themselves (see architecture-guidelines).

Skill-Library Optimization Mode

When the subject is the skills themselves, optimize in this order:

1. Define the behavioral failure, bottleneck, or drift risk; do not start from preferred wording.
2. Check whether validation can catch it: mirror sync, frontmatter, primer backlinks, output contract presence, owner/routing conflicts, or template shape.
3. Edit the owning SKILL.md only. Sibling skills get cross-references unless they must make a routing decision.
4. Keep .agents/skills, .claude/skills, and the matching .documentation/READ-*.md primer aligned in the same change. If the skill's public role or trigger changed, update the README.md skill index too.
5. Run python scripts/validate-skills.py. If no mechanical check can cover the lesson, record why in the output contract.

Consumer-to-Library Promotion

Use this sequence when learning originates in a consumer project:

1. Capture the concrete failure, correction, or repeated successful pattern and its verification evidence in the consumer.
2. Extract the smallest behavior that applies without the project name, private paths, roles, domain taxonomy, local commands, or provider assumptions.
3. Update the one canonical generic owner in the skill library. Add a skill only when the capability has a distinct trigger, lifecycle, and output contract.
4. Update mirrors, primers, indexes, root routing guidance, and validation in the same library change.
5. Validate and publish the library revision.
6. Repin or reinstall that revision in the consumer, then retain only its project profile and other domain-specific skills locally.

Do not overwrite a generic library from a consumer tree or treat byte-identical vendored files as locally owned. If a local emergency patch is unavoidable, mark it as temporary divergence with an upstream owner and remove it when the published fix is repinned.

1. Triggers for Learning

Initiate this protocol to examine and update existing SKILL.md files when encountering:

Trigger Type	Scenario
Correction	User explicitly corrects an architectural pattern, approach, or rule.
Regression	A fix for one issue breaks another, indicating an undocumented system boundary.
New Pattern	A new, validated structural standard is successfully introduced to the codebase.
Systemic Failure	The same class of anti-pattern or fragile workaround is attempted repeatedly, or once with high blast radius.
Process Break	Recurring CI/CD failures or linter bottlenecks indicating a broken foundational rule.
Skill Optimization	User asks to optimize, prune, audit, or increase efficiency of the skill library itself.

2. Analyze Root Cause

Determine the underlying reason before writing a new rule. Ask:

• Missing/Ambiguous: Was the requirement undocumented, too broad, too absolute, or written with the wrong force?
• Conflict: Did two SKILL rules contradict each other?
• Ignored Rule: Was a rule clear but ignored due to lack of visibility in the file? Improve placement or wording before promoting it to a warning block.
• Technical Constraint: Was the failure due to a misunderstood platform or framework behavior?

3. The Update Execution

When generating the actual update to the relevant SKILL.md file:

• Actionable Constraints: Ensure new rules are testable, direct, scoped, and explicit about exceptions.
• Review Sibling Skills: Check existing skills to ensure you are not creating an ownership conflict or duplicating the rule's primary authority.
• Eliminate Outdated Logic: Replace or delete previous rules only when they contradict, overlap with, or are made obsolete by the new learning. Preserve useful exceptions and migration notes.
• Maintain Mirrors: When this library has both .agents/skills and .claude/skills copies, keep the matching SKILL.md files synchronized and align the corresponding .documentation/READ-*.md primer and any affected README.md skill-index text.
• Validate Shape: Run the repo's skill validator after edits; extend it when a drift pattern can be detected mechanically.

4. Verification & Notification

Ensure the learning "sticks":

• Verification: If applicable, add a unit test, lint rule, schema check, or perform an audit showing the previous mistake is now caught earlier or made less likely. Do not claim structural impossibility unless an enforced gate guarantees it. For skill-library changes, run python scripts/validate-skills.py.
• Notify: Conclude the improvement sequence with a concise summary back to the user:

  "Updated [Skill/Test] to prevent [issue] by mandating [new practice]."

5. Output Contract

When applying this skill, emit:

Subject:        <skill / test / linter / schema / template>
Trigger:        <correction | regression | new pattern | systemic failure | process break | skill optimization>
Root cause:     <missing/ambiguous | conflict | ignored rule | technical constraint | ownership gap>
Owner:          <skill/test/linter/schema/template that should own the fix>
Automation:     <implemented | infeasible | deferred> - <reason>
Decision:       <replace | add | delete | cross-reference | no change>
Verification:   <test/lint/audit/search performed>
Next action:    <edit made, check added, follow-up owner, or stop>
Residual risk:  <what still depends on judgment or future enforcement>
