Review Mistakes

Interactively review pending mistake reports from the Intent Layer learning loop.

Overview

When agents make mistakes during development, skeleton reports are auto-captured in .intent-layer/mistakes/pending/. This skill helps you and the user review these reports conversationally, deciding which should become pitfalls in the Intent Layer.

Prerequisites

Check for pending reports:

ls -la ${CLAUDE_PROJECT_DIR:-.}/.intent-layer/mistakes/pending/

Workflow

Step 1: List Pending Reports

find "${CLAUDE_PROJECT_DIR:-.}/.intent-layer/mistakes/pending" \
  \( -name "MISTAKE-*.md" -o -name "SKELETON-*.md" \) \
  -type f 2>/dev/null | sort

If no reports, inform the user there's nothing to review.

Step 2: For Each Report

Read the report and present a summary:

---
**Report**: SKELETON-2026-01-23-1234.md

**Directory**: src/auth/
**Operation**: Edit on login.ts
**What happened**: Tool Edit failed - old_string not found
**Covering node**: src/auth/AGENTS.md

**Analysis**: [Your assessment - is this a real mistake or exploratory?]
---

Step 3: Ask User Decision

Present options clearly:

What would you like to do with this report?

1. •Accept - This is a real gotcha, add as pitfall to AGENTS.md
2. •Reject - Not useful (I'll ask for a reason)
3. •Discard - Exploratory failure, not a real mistake
4. •Enrich - Add more context before deciding
5. •Skip - Review later

Step 4: Execute Decision

On Accept

Run the integration script:

${CLAUDE_PLUGIN_ROOT}/lib/integrate_pitfall.sh "${CLAUDE_PROJECT_DIR:-.}/.intent-layer/mistakes/pending/<filename>"

This will:

• •Find the covering AGENTS.md
• •Extract/generate a pitfall entry
• •Append to the Pitfalls section
• •Move report to integrated/

On Reject

Ask for rejection reason, then:

# Create rejected directory if needed
mkdir -p "${CLAUDE_PROJECT_DIR:-.}/.intent-layer/mistakes/rejected"

# Add rejection reason to file
echo -e "\n### Rejection\n**Reason**: <reason>\n**Date**: $(date -u +"%Y-%m-%dT%H:%M:%SZ")" >> "<file>"

# Move to rejected
mv "<file>" "${CLAUDE_PROJECT_DIR:-.}/.intent-layer/mistakes/rejected/"

On Discard

Simply delete the skeleton:

rm "<file>"

Confirm to user: "Discarded - this was an exploratory failure, not a real mistake."

On Enrich

Open the file for editing or help the user add:

• •Better description of what went wrong
• •Root cause analysis
• •Suggested pitfall text

Then return to Step 3.

On Skip

Move to the next report. Track skipped files to mention at the end.

Step 5: Summary

After reviewing all reports (or when user wants to stop):

## Review Summary

- **Accepted**: 2 (pitfalls added to AGENTS.md)
- **Rejected**: 1
- **Discarded**: 3 (exploratory failures)
- **Skipped**: 1 (still pending)

Remaining pending: 1 report(s)

Report Types

Skeleton Reports (SKELETON-*.md)

Auto-created by PostToolUseFailure hook. Contains:

• •Tool and file context
• •Placeholder fields for root cause and suggested fix
• •Often exploratory failures - review carefully

Common skeleton dispositions:

• •Discard if: Edit failed because string wasn't found (typo, wrong file)
• •Discard if: Bash command failed during exploration
• •Accept if: Failure revealed a non-obvious gotcha about the codebase
• •Enrich then Accept if: Real mistake but needs better description

Full Reports (MISTAKE-*.md)

Created manually via capture_mistake.sh. Contains:

• •Detailed description from human/agent
• •Root cause analysis
• •Suggested fix

Common full report dispositions:

• •Accept if: Well-documented, clear pitfall
• •Reject if: One-off issue, not worth documenting
• •Enrich then Accept if: Good insight but needs clearer pitfall text

Example Conversation

Agent: "I found 3 pending mistake reports. Would you like to review them now?"

User: "yes"

Agent:

---

Report: SKELETON-2026-01-23-4521.md

Directory: src/api/ Operation: Edit on routes.ts What happened: Edit failed - old_string not found Covering node: src/api/AGENTS.md

Analysis: This looks like the Edit tool couldn't find the exact string to replace. This could be:

• •A typo in the old_string (exploratory)
• •The file had been modified and the string changed (possible gotcha)

---

What would you like to do? (1) Accept (2) Reject (3) Discard (4) Enrich (5) Skip

User: "3 - it was just a typo"

Agent: "Discarded. Moving to next report..."

Tips

• •Be conservative with Accept - Only document genuine gotchas that would trip up future agents
• •Discard freely - Most skeletons from exploratory failures should be discarded
• •Enrich before Accept - A well-written pitfall is more useful than a vague one
• •Batch review - Review all pending reports periodically rather than one at a time
