Codex Project Memory

TL;DR

11 scripts for project knowledge persistence. Decision tree: Log -> decision/feedback/skill-usage. Generate -> changelog/session-summary/handoff/growth-report. Analyze -> patterns/knowledge-graph/project-genome. Maintain -> compact old context. Triggers: $changelog, $growth-report, $session-summary, $log-decision, $compact-context, $codex-genome.

Codex Project Memory

Activation

1. Activate after complex tasks involving architecture, design decisions, or refactors.
2. Activate on explicit $codex-project-memory or $memory.
3. Activate on explicit command $log-decision.
4. Activate on $handoff or when user asks to generate handoff context.
5. Activate on $session-summary or when user asks to summarize a coding session.
6. Activate on $analyze-patterns or "learn project style".
7. Activate on $log-feedback or "track my fix".
8. Activate on $feedback-summary for aggregated feedback recall.
9. Activate on $skill-track to record skill usage analytics.
10. Activate on $skill-report to generate skill evolution report.
11. Activate on $build-graph or "map project" to generate project knowledge graph.
12. Activate on $changelog to generate release-oriented commit summaries.
13. Activate on $growth-report to generate a developer growth report.
14. Activate on $compact-context or "clean up old sessions".
15. Activate on $codex-genome, $generate-genome, or $genome to create layered project context docs.

Rules

• Use the decision tree to choose one memory action before invoking scripts.
• Run --help before invoking helper scripts and treat them as black-box tools unless customization or bug fixing is required.
• Review existing files in .codex/decisions/ before logging a similar technical choice.
• Use the default output paths and chaining guidance from references/behavior-guide.md unless the user requests overrides.
• Return the created path plus the headline metrics from each script JSON payload.
• Xem skills/.system/REGISTRY.md để biết đường dẫn đầy đủ.
