name	self-improve
description	Codex-specific, session-driven self-improvement for Codex behavior and project instructions. Use when the user asks to inspect past Codex sessions, run a "dream" pass over prior interactions, mine repeated user corrections/preferences, improve or draft skills, update repo/project `AGENTS.md` guidance, or propose durable edits to global `~/.codex/AGENTS.md`.

Self Improve

Overview

Use this Codex-specific skill to inspect prior Codex threads and generate evidence-backed improvement proposals for three targets: skills, project-local AGENTS.md, and global ~/.codex/AGENTS.md.

This skill depends on Codex's local session system (~/.codex/state_5.sqlite plus rollout JSONL files under ~/.codex/sessions and ~/.codex/archived_sessions). It is not intended to work unchanged in non-Codex agent runtimes.

Workflow

1. Run the session browser to identify candidate threads:

   python3 scripts/self_improve.py list --limit 25 --archived all
   

2. Render specific sessions as readable transcripts when you need direct evidence:

   python3 scripts/self_improve.py show <thread-id>
   

3. Run a dream pass to mine repeated user corrections and workflow preferences:

   python3 scripts/self_improve.py dream --limit 250 --days 365 --min-support 2 --min-confidence 0.6 --emit-patch
   

4. Run a skill audit when you want per-skill SKILL.md improvements instead of global/project instruction updates:

   python3 scripts/self_improve.py skill-audit --limit 500 --days 365 --min-support 1 --min-confidence 0.6 --emit-patch
   

5. Read the proposal buckets and decide what to patch:

   • Skills: tighten existing SKILL.md, add scripts/references, or create a new skill.
   • Project AGENTS.md: update the nearest repo/vault instruction file for a project-specific preference.
   • Global AGENTS.md: add durable defaults that should apply across all repos.

6. When the user asks about frustration or persistence, inspect cited examples with show and specifically look for repeated continue, keep going, don't stop, Come on, and “can't you just...” messages before proposing global behavior rules.

Source Of Truth

• Treat ~/.codex/state_5.sqlite as the authoritative session index.
• Use each row's threads.rollout_path to load full rollout JSONL transcripts from ~/.codex/sessions/... or ~/.codex/archived_sessions/....
• Treat ~/.codex/session_index.jsonl as an incomplete convenience index, not the source of truth.
• Use ~/.codex/memories/MEMORY.md and ~/.codex/memories/memory_summary.md as supporting context only. Do not write them by default.

Proposal Rules

• Default to propose-first. Do not patch SKILL.md, project AGENTS.md, or global ~/.codex/AGENTS.md until the user explicitly approves the proposed edits.
• Separate facts from inference. Every proposal must cite one or more concrete thread IDs plus timestamps and rollout paths.
• Do not overfit one-off phrasing. Prefer repeated corrections, repeated style/tooling requests, and instructions that are likely to recur.
• Treat Support as deduped thread clusters, not raw thread IDs, so same-day retries of one task do not inflate one proposal.
• Use Confidence to suppress one-off task noise. If a proposal still reads like a transient implementation ask, inspect its cited sessions with show before patching.
• Keep proposal buckets disjoint. If a preference belongs in a project AGENTS.md, do not also copy the same rule into global ~/.codex/AGENTS.md unless it clearly applies across repos.
• For project proposals, infer the nearest target AGENTS.md from the session cwd; prefer the closest existing AGENTS.md/AGENTS.MD, then repo root, then cwd/AGENTS.md.
• For skill proposals, map edits to an existing skill folder under ~/.codex/skills or ~/.agents/skills when the transcript or cwd makes that unambiguous; otherwise propose a new skill path under ~/.codex/skills/<name>/SKILL.md.
• Use skill-audit when the question is “which existing skills should be improved?” because it suppresses suggestions already present in each target SKILL.md and emits only uncovered rules per skill.
