Recent Failures (Last 24 Hours)
================================

2025-01-08 14:28:15  imbue:proof-of-work
  Duration: 1.9s
  Error: Missing PROOF.md file
  Session: abc123

  Context:
    Tool input: {"skill": "imbue:proof-of-work", "args": {"path": "/project"}}
    Output preview: "Error: Required file PROOF.md not found in project root..."

  Recommendation:
    - Check that PROOF.md exists before invoking
    - See /skill-review --skill imbue:proof-of-work for stability analysis

2025-01-08 12:15:42  your-custom:my-skill
  Duration: 3.2s
  Error: Failed to connect to database
  Session: def456

  Context:
    Tool input: {"skill": "your-custom:my-skill", "args": {"query": "SELECT..."}}
    Output preview: "ConnectionError: Unable to establish connection..."

  Recommendation:
    - Verify database connection string
    - Check network connectivity

Full Context Mode

/skill-history --skill abstract:skill-auditor --context --last 24h

Shows complete tool input/output for debugging.

JSON Output

/skill-history --format json --last 1h | jq '.[] | select(.outcome == "failure")'

What It Shows

Per Execution

| Field | Description | |-------|-------------| | **Timestamp** | When the skill was invoked | | **Skill** | Plugin:skill reference | | **Outcome** | ✓ success, ✗ failure, ⚠ partial | | **Duration** | Execution time | | **Error** | Error message (if failed) | | **Session** | Claude session ID | | **Context** | Tool input and output preview |

Filtering

• **By plugin**: Show only skills from one plugin
• **By skill**: Focus on specific skill
• **By time**: Recent executions only
• **By outcome**: Failures, successes, or all

Integration

Data Source

Reads from execution logs stored by memory-palace:

• **Location**: `~/.claude/skills/logs/<plugin>/<skill>/YYYY-MM-DD.jsonl`
• **Format**: One JSON object per line (JSONL)

Related Commands

| Command | Focus | Use When | |---------|-------|----------| | `/skill-history` | Recent executions | Debugging a specific failure | | `/skill-review` | Metrics & stability | Understanding overall health | | `/skill-logs` | Raw log access | Data export or cleanup |

Use Cases

Debugging a Failure

# 1. See recent failures
/skill-history --failures-only --last 1h

# 2. Get full context for the problematic skill
/skill-history --skill imbue:proof-of-work --context

# 3. Check if it's a pattern
/skill-review --skill imbue:proof-of-work

Understanding Usage Patterns

# What skills are being used most?
/skill-history --last 7d --format json | jq 'group_by(.skill) | map({skill: .[0].skill, count: length}) | sort_by(-.count)'

Session Reconstruction

# What skills ran in a specific session?
/skill-history --format json | jq 'select(.context.session_id == "abc123")'

Performance

• Scans JSONL files by date to minimize I/O
• Limits output to prevent context overflow
• Use `--last` to narrow time range for faster results
