Recall Past Work

1. Artifact Index - Handoffs, plans, ledgers with post-mortems (what worked/failed)
2. Reasoning Files - Build attempts, test failures, commit context

When to Use

• Starting work similar to past sessions
• "What did we do last time with X?"
• Looking for patterns that worked before
• Investigating why something was done a certain way
• Debugging an issue encountered previously

Usage

Primary: Artifact Index (rich context)

uv run python scripts/core/artifact_query.py "<query>" [--outcome SUCCEEDED|FAILED] [--limit N]

Secondary: Reasoning Files (build attempts)

bash "$CLAUDE_PROJECT_DIR/.claude/scripts/search-reasoning.sh" "<query>"

.git/claude/commits/*/reasoning.md

Examples

# Search for authentication-related work
uv run python scripts/core/artifact_query.py "authentication OAuth JWT"

# Find only successful approaches
uv run python scripts/core/artifact_query.py "implement agent" --outcome SUCCEEDED

# Find what failed (to avoid repeating mistakes)
uv run python scripts/core/artifact_query.py "hook implementation" --outcome FAILED

# Search build/test reasoning
bash "$CLAUDE_PROJECT_DIR/.claude/scripts/search-reasoning.sh" "TypeError"

What Gets Searched

• Task summaries and status
• What worked - Successful approaches
• What failed - Dead ends and why
• Key decisions - Choices with rationale
• Goal and constraints from ledgers

.git/claude/

• Failed build attempts and error output
• Successful builds after failures
• Commit context and branch info

Interpreting Results

• ✓

  = SUCCEEDED outcome (pattern to follow)

• ✗

  = FAILED outcome (pattern to avoid)

• ?

  = UNKNOWN outcome (not yet marked)
• Post-mortem sections show distilled learnings

• build_fail

  = approach that didn't work

• build_pass

  = what finally succeeded
• Multiple failures before success = non-trivial problem

Process

1. Run Artifact Index query first - richer context, post-mortems
2. Review relevant handoffs - check what worked/failed sections
3. If needed, search reasoning - for specific build errors
4. Apply learnings - follow successful patterns, avoid failed ones

No Results?

• Run

  uv run python scripts/core/artifact_index.py --all

  to index existing handoffs
• Create handoffs with post-mortem sections for future recall

• Use

  /commit

  after builds to capture reasoning
• Check if

  .git/claude/

  directory exists
