modbender failure-memory (記憶)
Unified skill for failure detection, observation recording, memory search, and pattern convergence. Consolidates 10 granular skills into a single coherent memory system.
Trigger: 失敗発生 (failure occurred)
Source skills: failure-tracker, observation-recorder, memory-search, topic-tagger, failure-detector, evidence-tier, effectiveness-metrics, pattern-convergence-detector, positive-framer, contextual-injection
Installation
openclaw install leegitw/failure-memory
Dependencies: leegitw/context-verifier (for file change detection)
# Install with dependencies
openclaw install leegitw/context-verifier
openclaw install leegitw/failure-memory
Standalone usage: This skill can function independently for basic failure tracking. For full lifecycle management, install the complete suite (see Neon Agentic Suite).
Data handling: This skill operates within your agent's trust boundary. When triggered,
it uses your agent's configured model for failure detection and pattern recording. No external APIs
or third-party services are called. Results are written to .learnings/ in your workspace.
What This Solves
AI systems often make the same mistakes repeatedly — deleting working code, missing edge cases, forgetting context. This skill turns failures into learning by:
- Detecting failures when they happen (not after)
- Recording observations with R/C/D counters (Recurrence/Confirmations/Disconfirmations)
- Finding patterns within the workspace's
.learnings/directory - Promoting to constraints when evidence threshold is met
The insight: Systems learn better from consequences than instructions. A failure that happened teaches more than a rule that might apply.
Scope note: Pattern detection operates within the current workspace only. Observations are stored in
.learnings/and searched locally. No cross-project data access occurs.

Detection Triggers
These patterns indicate when /fm detect should be invoked (user or orchestrator triggers):
| Pattern | Source | Action |
|---|---|---|
test.exit_code != 0 |
Tool output | /fm detect test |
| "Actually...", "No, that's wrong" | User message | /fm record correction |
| "I meant...", "Not X, Y" | User message | /fm record correction |
| API 4xx/5xx response | Tool output | /fm detect api |
| "error:", "failed", "Exception" | Tool output | /fm detect error |
| Deployment rollback | CI/CD output | /fm detect deployment |
| Database migration failed | Tool output | /fm detect migration |
Example: API Failure Detection
[DETECTED] api failure
Pattern: payment-api-timeout
Context: Payment API returned 504 after 30s
Observation: OBS-20260215-002
R: 1 → 3
Status: Eligible for constraint (R≥3)
Example: Deployment Failure Detection
[DETECTED] deployment failure
Pattern: staging-healthcheck-fail
Context: Staging deployment failed health check on /api/health
Observation: OBS-20260215-003
R: 1 → 2
Status: Monitoring (R<3)
Core Logic
R/C/D Counters
| Counter | Meaning | Updated By |
|---|---|---|
| R (Recurrence) | Auto-detected occurrences | /fm detect, /fm record |
| C (Confirmations) | Human-verified true positives | Human via /fm record C |
| D (Disconfirmations) | Human-verified false positives | Human via /fm record D |
Evidence Tiers
| Tier | Criteria | Meaning |
|---|---|---|
| 弱 (weak) | N=1 | Single occurrence, may be noise |
| 中 (emerging) | N=2 | Pattern emerging, monitor |
| 強 (strong) | N≥3 | Established pattern, actionable |
Slug Taxonomy
Observations are tagged with slugs: git-*, test-*, workflow-*, security-*, docs-*, quality-*
Metrics
prevention_rate: Failures prevented / Total potential failuresfalse_positive_rate: D / (C + D)

.openclaw/failure-memory.yaml(OpenClaw standard).claude/failure-memory.yaml(Claude Code compatibility)- Defaults (built-in)
# .openclaw/failure-memory.yaml
detection:
auto_detect: true # Enable automatic failure detection
patterns: # Custom detection patterns
- "FATAL:"
- "CRITICAL:"
thresholds:
eligibility_R: 3 # Recurrence threshold (default: 3)
eligibility_C: 2 # Confirmation threshold (default: 2)
false_positive_max: 0.2 # Max D/(C+D) ratio (default: 0.2)
Integration
- Layer: Core

Failure Modes
| Condition | Behavior |
|---|---|
| Invalid sub-command | List available sub-commands |
| Missing observation ID | Error with usage example |
| No matches found | "No observations match query" |
| Duplicate detection | Increment R counter, don't create new observation |
Next Steps
After invoking this skill:
| Condition | Action |
|---|---|
| R incremented | Check eligibility: R≥3 ∧ C≥2 → notify user |
| R≥3 ∧ C≥2 | Suggest /ce generate for constraint |
| Pattern recurring | Link with See Also, bump priority |
| Always | Update .learnings/ERRORS.md or .learnings/LEARNINGS.md |
Workspace Files
This skill reads/writes:
.learnings/
├── ERRORS.md # [ERR-YYYYMMDD-XXX] command failures

Security Considerations
What this skill accesses:
- Configuration files in
.openclaw/failure-memory.yamland.claude/failure-memory.yaml - Tool output and user messages in the current session (for failure detection)
- Its own workspace directory
.learnings/(read/write)
What this skill does NOT access:
- Files outside declared workspace paths
- System environment variables
- Other projects or sessions (observations are workspace-local)
- Network resources or external APIs
What this skill does NOT do:
- Send data to external services
- Access "across sessions and projects" beyond the current workspace
- Execute arbitrary code or run external commands
Data scope clarification:
- "Failure detection" scans tool output and user messages within the current agent session
- Observations are stored in
.learnings/within the current workspace only - No cross-project or cross-session data access occurs
- Pattern matching is local to the configured workspace
Detection trigger clarification:
The "Detection Triggers" table describes patterns that indicate when this skill should be
invoked. The agent can auto-invoke /fm detect when these patterns are detected, or users
can invoke manually. This enables true agentic behavior — failures are captured automatically.
Provenance note:
This skill is developed by Live Neon (https://github.com/live-neon/skills) and published
to ClawHub under the leegitw account. Both refer to the same maintainer.
