Mine the current conversation for durable learnings, then route them into skill edits.
Invoke when the user says "reflect" or "/reflect". Skip when the conversation is trivial, off-topic, or already covered by an existing skill the parent followed correctly. One-offs are not learnings.
1. Locate the active transcript
The parent finds its own transcript file before fanning out: the newest session in this workspace's transcript store. Use the pstack-harness skill to locate it. Do not read other workspaces' transcript stores. That crosses workspace boundaries and reads private chats from unrelated projects.
ls -t <agent-transcripts>/*.jsonl <agent-transcripts>/*/*.jsonl <agent-transcripts>/*/subagents/*.jsonl 2>/dev/null | head -10
That covers the legacy flat (<id>.jsonl), current nested (<id>/<id>.jsonl), and subagent (<parent>/subagents/<child>.jsonl) layouts. For each candidate, read the first JSONL line. Take the file whose message.content[0].text contains the conversation's opening user prompt. If none matches, pass a tight digest of the session instead.
2. Spawn three reviewers in parallel
One message, three Task calls, subagent_type: general-purpose, with model set as below, agent mode (readonly: false). Reviewers need MCP access to look up the tickets, chat threads, and observability traces the transcript references, and readonly strips MCPs. Use the pstack-harness skill for the spawn. Its Spawn a role section resolves the role and builds this CLI's spawn call.
Each reviewer and the synthesizer name a role line in the pstack models config and a default. Use the pstack-harness skill to resolve its model, effort, and agent type. Its Spawn a role section also covers a missing config, inherit-parent, and a rejected value.
| Lens | Role line | Default model |
Prompt template |
|---|---|---|---|
| Judgment | reflect judgment, divergent, synthesizer |
opus |
references/judgment-reviewer.md |
| Tooling | reflect tooling |
opus |
references/tooling-reviewer.md |
| Divergent | reflect judgment, divergent, synthesizer |
opus |
references/divergent-reviewer.md |
Pass each template verbatim, substituting the transcript path or digest where marked. Reviewers return findings in the Task response body.
3. Synthesize
One Task call, subagent_type: general-purpose, model from the reflect judgment, divergent, synthesizer line (default opus), agent mode (readonly: false). It spot-verifies citations through MCP, and readonly strips MCPs. Pass references/synthesizer.md verbatim, with each reviewer's full output inlined where marked. It returns an Accepted / Rejected / Backlog list.
4. Structural enforcement check
Move any Accepted item that a lint rule, script, metadata flag, or runtime check would enforce more reliably to Backlog. See the encode-lessons-in-structure principle skill.
5. Apply
Present the synthesizer's full Accepted / Rejected / Backlog output and wait for explicit approval before applying any Accepted edit. The user picks the subset and may redirect routings. Skill changes affect every future agent in the org. Do not auto-apply.
File each ordinary Backlog item to your team's devex or backlog tracker without waiting. Security, privacy, auth, data, and permission-boundary findings are the exception. Keep those findings private and report them to the operator directly. Never post or link them in a public tracker, issue, PR, or comment. Only the Accepted list waits for approval.
Follow each approved row's Routing exactly:
- Trivial existing-skill edit (a one-line bullet, a tightened sentence, a stale fact corrected): the parent does it directly.
- Substantive existing-skill edit (a new section, a new pattern table, more than ~10 lines): follow the authoring guidance in
../poteto-mode/playbooks/authoring-a-skill.mdand run a draft / test / iterate loop. tune description: <skill path>(the skill exists but didn't trigger when it should have): rewrite the description per../poteto-mode/playbooks/authoring-a-skill.mdand run a description-optimization loop (test phrasings that should and should not trigger it).new skill: <kebab-name>: create it per../poteto-mode/playbooks/authoring-a-skill.md. Do not invent the shape ad hoc.
If your environment ships a SKILL.md validator, run it on every touched skill before declaring done.
6. Summarize for the user
Short list, no preamble:
- Edits applied:
<skill path>. What changed, one line each. - New skills created:
<skill path>. One line each (rare). - Backlog filed to the devex tracker:
<issue title>(<tags>). One line each. - Dropped: one line per rejected finding + reason from the synthesizer.
