Pre-Write Dedupe Check (Required) +- Search existing lessons/memories for similar root cause, decision, impacted area, and applicability. +- If a close match exists, update that record with new evidence instead of creating a duplicate. +- Create a new file only when the pattern is materially distinct. + +3. Conflict Resolution (Required) +- If new evidence conflicts with an existing `active` pattern, do not keep both as active. +- Mark the older conflicting pattern as `deprecated` (or `blocked` if unsafe). +- Create/update the replacement pattern and link with `Supersedes`. +- Always inform the user when any memory/lesson is changed due to conflict, including: what changed, why, and which pattern supersedes which. + +4. Safety Gate (Required) +- Never apply or recommend patterns with `Status: blocked`. +- Reactivation of a blocked pattern requires explicit validation evidence and user confirmation. + +5. Reuse Priority (Required) +- Prefer the newest validated `active` pattern. +- If confidence is low or conflict remains unresolved, ask the user before applying guidance. + +### Lessons (`.github/Lessons`) + +When a mistake occurs, create a markdown file documenting what happened and how to prevent recurrence. + +Template skeleton: + +```markdown +# Lesson: + +## Metadata +- PatternId: +- PatternVersion: +- Status: active | deprecated | blocked +- Supersedes: +- CreatedAt: +- LastValidatedAt: +- ValidationEvidence: + +## Task Context +- Triggering task: +- Date/time: +- Impacted area: + +## Mistake +- What went wrong: +- Expected behavior: +- Actual behavior: + +## Root Cause Analysis +- Primary cause: +- Contributing factors: +- Detection gap: + +## Resolution +- Fix implemented: +- Why this fix works: +- Verification performed: + +## Preventive Actions +- Guardrails added: +- Tests/checks added: +- Process updates: + +## Reuse Guidance +- How to apply this lesson in future tasks: +``` + +### Memories (`.github/Memories`) + +When durable context is discovered (architecture decisions, constraints, recurring pitfalls), create a markdown memory note. + +Template skeleton: + +```markdown +# Memory: + +## Metadata +- PatternId: +- PatternVersion: +- Status: active | deprecated | blocked +- Supersedes: +- CreatedAt: +- LastValidatedAt: +- ValidationEvidence: + +## Source Context +- Triggering task: +- Scope/system: +- Date/time: + +## Memory +- Key fact or decision: +- Why it matters: + +## Applicability +- When to reuse: +- Preconditions/limitations: + +## Actionable Guidance +- Recommended future action: +- Related files/services/components: +``` + +## Large Codebase Architecture Reviews + +For large, complex codebases: +- Build a system map (boundaries, dependencies, data flow, deployment topology). +- Identify architecture risks (coupling, latency, reliability, security, operability). +- Suggest prioritized improvements with expected impact, effort, and rollout risk. +- Prefer incremental modernization over disruptive rewrites unless justified. + +## Web and Agentic Tooling + +Use available web and agentic tools for validation, external references, and decomposition.
