description

Extract lessons from the current session, or sweep the project's past sessions when asked, and route them to the appropriate knowledge layer (project AGENTS.md, auto memory, existing skills, or new skills). Use when the user asks to "self-improve", "distill this session", "distill past sessions", "sweep past sessions", "extract lessons from all sessions", "save learnings", "update AGENTS.md with what we learned", "capture session insights", "remember this for next time", "extract lessons", "update skills from session", or "what did we learn".

Self-Improve

Review the current conversation, or the project's past sessions when asked, to extract durable lessons and route each one to the right knowledge layer.

Step 1: Detect Context

Available destinations:

• Project AGENTS.md — AGENTS.md in the project root, plus any nested AGENTS.md files in subdirectories. A nested file scopes its guidance to that subtree, so a lesson scoped to one subtree belongs in the nearest enclosing file, with the root reserved for project-wide rules.
• Auto memory — Codex memory, if the active harness exposes a project-specific memory file. If no memory location is available, skip this destination.
• Skills — Project skills at .agents/skills/ (walked from project root down to cwd) and user-installed skills at ~/.agents/skills/ (resolve symlinks)

Discover the project AGENTS.md files (the root file and any nested ones in subdirectories) and read them, then read any available Codex memory. When those files point at a knowledge base the repo maintains, read its index too; it is a documentation source for Step 3 rather than a routing destination. List all skill directories but do not read them yet — Step 2 needs to run first so you know what to look for.

Turbo Skill Detection

If ~/.turbo/repo/ exists, identify which installed skills are turbo skills:

• List directories in ~/.turbo/repo/codex/skills/
• Any skill in ~/.agents/skills/ that has a matching directory in ~/.turbo/repo/codex/skills/ is a turbo skill
• Skills only in ~/.agents/skills/ (no match in the repo) are user/project skills

Verification rule (mandatory before routing in Step 4): For every candidate skill that is about to be routed as turbo, confirm with a fresh test -d ~/.turbo/repo/codex/skills/<name> check that the skill actually lives in the turbo repo. Do not rely on remembered listings from earlier in the session, filename hits in grep output, or assumptions based on where a SKILL.md was read from. A miss here mislabels a user/project skill as turbo, triggers the contribution flow unnecessarily, and can introduce session-specific content into a shared skill — so the check is not optional.

Exception: If the current project IS the turbo repo (i.e., the working directory contains this skill collection), route turbo skill lessons through the Existing user/project skill destination in Step 4 — edits go directly to codex/skills/<name>/ in the project, with no installed-copy indirection and no contribution flow.

Step 2: Gather Session Evidence and Scan for Lessons

Recover Pre-Compaction Evidence

Skip when the conversation is visible in full from the user's own first message.

When it starts from a summary of earlier work instead, recover the compacted turns from the on-disk rollout file. Spawn a single sub-agent (inherited model defaults). The sub-agent's prompt must include:

1. The absolute path of the project root
2. A distinctive phrase from the visible conversation, for confirming which rollout file belongs to this session
3. An instruction to read references/transcript-miner.md for rollout file location, extraction, and output format

Treat the returned items as raw evidence for the scan below.

Sweep Past Sessions

Run when asked to distill sessions beyond the current one. Skip otherwise.

Propose a cutoff first. When Step 1 found a memory location, take its newest modification time, state it, then use request_user_input to confirm sweeping from it or sweeping the whole history; when that gate cannot reach the user, sweep from the proposed cutoff and say so in the report. A memory file's timestamp records a write rather than a completed sweep, so it bounds the work without settling what a previous run covered. When no memory location is available, sweep the whole history without asking.

Spawn a single sub-agent (inherited model defaults). The sub-agent's prompt must include:

1. The absolute path of the project root
2. The confirmed cutoff as an ISO-8601 timestamp, or that there is none
3. An instruction to read references/transcript-miner.md and follow its sweep process

Treat the returned items as raw evidence for the scan below.

Identify Session Skills

Before scanning for lessons, identify which skills were loaded during this session:

• Scan the conversation for Turbo skill invocations and SKILL.md reads from ~/.agents/skills/
• Build a list of session skills, marking each as turbo or user/project skill (using the detection from Step 1)
• This list informs routing in Step 4: when a lesson clearly arose from a specific skill's workflow, that skill is the natural routing target

Scan for Lessons

Scan the full conversation with this priority:

1. Corrections — Where the user interrupted, said "no", "actually", "stop", "not like that", redirected, or manually fixed something Codex did wrong. Highest-value lessons.
2. Repeated guidance — Instructions the user gave more than once. Across separate sessions this counts even where each instance reads as ordinary steering on its own.
3. Skill-shaped knowledge — Domain expertise that was needed repeatedly, tool/API integration details that had to be looked up, decision frameworks that emerged for evaluating options, content templates or writing conventions that were refined, and multi-step workflows where ordering mattered (as reusable domain knowledge, not the workflow itself — see #4).
4. New workflows — Did this session establish a novel multi-step procedure, coordination pattern, or automation that worked? A successful workflow that would need to be repeated is a prime skill candidate — even if it ran fine this time. Distinct from #3: this captures the procedure itself as a repeatable artifact, not knowledge about how to do it. Flag it.
5. Preferences — Formatting, naming, style, or tool choices the user expressed.
6. Failure modes — Approaches that failed, with what worked instead. For tool or script call failures, trace back to the information source that led to the error and route the fix there (e.g., clarify a reference file, update skill instructions, add missing documentation).
7. Domain knowledge — Facts or conventions Codex needed but did not have.
8. Improvement opportunities — Out-of-scope improvements noticed during work: code that could be refactored, missing tests, performance issues, readability concerns, or feature ideas that were intentionally skipped to stay focused. Skipped findings count here: when code simplification or code review identified a genuine improvement or issue but it was skipped for this session, route it as a project improvement so it isn't lost.
9. Trusted reviewer feedback — Human PR review comments that reveal project conventions, patterns, or corrections. Trusted reviewers are repo collaborators with admin or maintain roles (determine via gh api repos/{owner}/{repo}/collaborators --jq '.[] | select(.role_name == "admin" or .role_name == "maintain") | .login'). Their feedback takes precedence over other reviewers and AI bots when there are contradictions.

After scanning, read all skill SKILL.md files (they are small). This gives Step 4 full context for routing.

Step 3: Filter

Keep only lessons that are:

• Stable — likely to remain true across future sessions
• Non-obvious — Codex would not already know this
• Actionable — can be expressed as a rule or instruction
• Not already documented — absent from the files read in Steps 1 and 2, from each skill's references/ and other supporting files, and from the project's own knowledge stores. Search all of those for each candidate's keywords rather than assuming. A lesson documented only in an unrelated subtree's AGENTS.md still counts as undocumented for the subtree it actually applies to.
• Still a concern — the issue is not already fixed by changes made in this session. If a bug was found and fixed, or a missing feature was added, future sessions will see the corrected code — they don't need a reminder about the old problem. Exception: successful workflows and procedures are not "resolved" — they're skill candidates precisely because they worked and will need to be repeated. When sweeping past sessions, judge this against the current state of the code and docs rather than against this session's changes.

Discard anything session-specific, speculative, one-off, or already resolved by code changes in this session (but not successful workflows — see exception above). If no lessons survive filtering, tell the user and stop.

Step 4: Route Each Lesson

Assign each surviving lesson to exactly one destination.

Skill-first rule (mandatory): Before consulting the table below, check whether the lesson corrects, refines, or adds a guardrail to any existing skill's behavior — turbo or user/project. This includes lessons about skipping steps, wrong defaults, missing edge cases, or any "don't do X when running $skill-name" correction. If yes, route to that skill. Do not route skill corrections to auto memory or AGENTS.md — they belong in the skill they correct. This rule is not a preference; it is a hard constraint that takes precedence over the table rows below.

Destination	Criteria
Project improvements	Actionable improvement to existing code: refactoring, performance, reliability, readability, testing, or DX. Not for documentation fixes — factual errors in AGENTS.md belong in the Project AGENTS.md row. Route to .turbo/improvements.md via the $note-improvement skill.
Auto memory	Discovered knowledge with no skill home: API quirks, debugging workarounds, compiler gotchas, tool pitfalls, user preferences. Must not overlap with any existing skill's domain — if it does, route to the skill instead (see skill-first rule above).
Project AGENTS.md	Intentional project decisions: conventions, architecture, stack choices, build setup, module boundaries. Also factual corrections to AGENTS.md content (wrong commands, outdated paths, incorrect conventions) — fix these directly, do not defer to Project improvements. When the lesson applies only to one subtree, route it to the nearest enclosing AGENTS.md; reserve the root file for project-wide decisions.
Existing user/project skill	Lesson would improve a skill's instructions, supporting files, or reference materials, add a missing edge case, correct its workflow, or refine its trigger conditions. Route to any skill whose domain covers the lesson — not just the skill worked on in this session. Changes go to the skill file directly. No contribution flow.
New skill	A cohesive body of knowledge emerged that deserves its own on-demand context. The test: would this knowledge be too large for an AGENTS.md section, and should it only be loaded when relevant? See the skill categories table below.
Existing turbo skill	Same criteria as Existing user/project skill above, but for turbo skills. Before routing here, run test -d ~/.turbo/repo/codex/skills/<name>; if the directory does not exist, route to the Existing user/project skill destination instead. Changes go to the installed copy at ~/.agents/skills/, and are flagged for contribution (see Step 6).
No destination	Does not clearly fit any destination. Drop it. Routing a weak lesson is worse than losing it.

Skill categories:

Category	What it encodes	Example
Domain expertise	Best practices, patterns, API preferences	SwiftUI expert, Core Data guide
Tool/Service integration	API references, operations, ID formats	Paddle, Stripe, Keycloak
Decision framework	Judgment criteria, confidence levels, triage	Evaluate findings, performance audit
Content template	Writing conventions, tone, structure	Drafting, blog post, changelog
Knowledge/Research	Information discovery, schema definitions	Knowledge base, research process
Orchestrated workflow	Stateful multi-step procedures	Process ticket, process income

Splitting heuristic: When a session creates scripts or multi-step procedures, split the lesson: a brief pointer goes to AGENTS.md (script names, purpose), and the full workflow goes to a skill. Don't collapse them into a single AGENTS.md entry.

Tiebreakers (in priority order):

1. Skill correction → skill (hard rule). Any lesson that corrects, constrains, or refines a skill's behavior MUST route to that skill. Never to auto memory, never to AGENTS.md. This is the highest-priority routing rule.
2. Turbo skill vs. AGENTS.md → always the turbo skill. Broader impact (benefits all turbo users), better scoped, loaded only when relevant.
3. Skill vs. AGENTS.md → always the skill. Skills are more discoverable, better scoped, and loaded only when relevant.
4. Skill vs. auto memory → always the skill. If a lesson falls within the domain of an existing skill, it goes to the skill. Auto memory is for knowledge that has no skill home.
5. AGENTS.md vs. auto memory — intentional decisions go to AGENTS.md. Discovered knowledge (gotchas, workarounds, quirks) goes to auto memory.
6. Lesson vs. improvement — if the item is knowledge to remember, it's a lesson. If it's work to do later, it's an improvement. They don't compete — the same session can produce both.

Step 5: Present Routing Plan

Output a table as text before making any changes:

| # | Lesson | Destination | Action |
|---|--------|-------------|--------|
| 1 | Always use X for... | Project AGENTS.md | Append to ## Conventions |
| 2 | The $create-pr skill should... | ~/.agents/skills/create-pr | Update Step 2 |
| 3 | Multi-step deploy workflow | New project skill | Create new skill |
| 4 | User prefers short commit msgs | Auto memory | Append to MEMORY.md |

For each lesson, show: concise summary, target file/skill, and whether it's an append, update-in-place, or new creation.

Then use request_user_input with these options: Approve or Reject.

Step 6: Execute

Apply approved changes in order:

1. Improvements — For items routed to project improvements, run the $note-improvement skill with the summary, location, and rationale for each.

2. Updates to auto memory — Read the target, find the right section, append or update in place, following the memory system conventions from the system prompt.

3. Updates to AGENTS.md — Read the target file selected in Step 4 (the root file or a nested subtree file), find the right section, append or update in place. Match the tone and format already present.

4. Updates to user/project skills — Run the $create-skill skill to apply changes to any file inside the skill directory (SKILL.md, references, scripts, assets).

5. New skills — Run the $create-skill skill for each new skill. Provide the trigger conditions and relevant context from the session.

6. Updates to turbo skills — For each lesson routed to a turbo skill:

   1. Read ~/.turbo/repo/codex/SKILL-CONVENTIONS.md so turbo-specific conventions are in context before any editing.
   2. Run the $create-skill skill to update the installed copy at ~/.agents/skills/<name>/.

   Once every turbo skill edit is in place and reviewed, use request_user_input to ask "These turbo skill improvements could benefit other users. Propose them upstream?" When the user confirms, run the $contribute-turbo skill once for all of them.

Then call update_plan to mark this step completed and continue with the next step of the active workflow.

Writing Guidelines

• Match the tone and format of the target file
• Use imperative mood and short declarative sentences
• Group related insights under a descriptive heading
• Omit rationale unless the rule would seem arbitrary without it
• Never include temporary state, in-progress work, or task-specific details
• Keep lessons generic—avoid overly concrete examples; state the rule, not the instance
• For AGENTS.md: write as agent documentation — project rules any AI agent on this repo should follow
• For auto memory: write as personal Codex notes — concise, operational, organized by topic
• For skills: follow the conventions in the existing skill collection
• For files that live in the repo (AGENTS.md and project skills): name only mechanisms that live in the repo too; describe an installed skill's behavior generically
