Compound Learnings Refresh

Compound Refresh

Audit the learnings under <root>/solutions/ against the current codebase, apply the maintenance actions the evidence supports, and deliver a complete per-doc report plus committed changes. The report and the corrected document set are the deliverables. The store only compounds value if every doc can be trusted.

Mode

Read references/modes.md now. It reads the mode off the arguments and defines what each mode may apply unattended, the stale-marking fallback, the question tools, and the CONCEPTS.md bootstrap.

Two rules hold in both modes. A failed write is recorded as recommended, and the run continues. And a question is asked through the host's blocking tool, or through the numbered-options fallback that reference defines. It is never silently skipped.

Worth lens

The ordinary refresh judges accuracy: is each doc still true and still distinct. It never deletes an accurate doc for holding knowledge the repo states elsewhere. That second judgment, worth, runs only when the user asked for it and confirmed it. It reads the whole scope against the codebase and can delete accurate docs.

Read the invocation arguments for that intent: the user wants the store cleaned up, culled, pruned, trimmed, upgraded, or brought to the capture bar, in any wording, rather than checked for drift. When the intent is present, state the reading back and confirm before any investigation:

You asked to clean up the learnings. Which do you want?
1. Delete or shorten docs the codebase already explains. A doc goes when a test, a code comment, or the instructions file states the same reasoning, and every cut quotes that file. Drift is fixed too. Scope: <scope>.
2. Fix drift only. Stale paths and links, duplicate docs, and guidance the code no longer supports. Nothing accurate is deleted.

On option 1, read references/worth-audit.md before Investigate; it adds the bar, the evidence rule, and the routing. On option 2, or when the intent is absent, do not read that reference and do not apply its test; the accuracy refresh is the whole run. Non-interactive mode cannot confirm, so references/modes.md states what an inferred intent does there.

Artifact Root

Resolve <root> when you first compose a <root>/solutions/ path. Pass the resolved <root>/solutions/ path to any subagent, not the config. Every subagent spawn omits the mode parameter, so the user's permission settings apply.

<!-- ce-docs-root:start -->

Resolve the CE artifact root <root> before composing any artifact path.

• Read docs_root from <repo-root>/.compound-engineering/config.yaml only (<repo-root> = git rev-parse --show-toplevel). Do not read it from config.local.yaml. Unset -> <root> is docs, exactly as before.
• Validate a set value: a repo-relative directory whose real, symlink-resolved path stays inside the repo and is neither the repo root nor under .git/. Otherwise stop with an error naming docs_root and the value -- never fall back to docs.
• Use <root> as the sole artifact location: create it if absent, compose each path as <root>/<subdir> with this skill's own subdirectory, and never also read docs.

<!-- ce-docs-root:end -->

Scope

Candidates are the .md files under <root>/solutions/, excluding README.md and anything under _archived/. A hint that matches nothing never widens the scope. Read references/scope.md for the narrowing strategy, what each mode does on a miss, the empty-store message, triage order, and the README-row cleanup each action carries.

Investigate

Read references/investigate.md for the staleness dimensions, auto-memory rules, subagent roles, and category-shape notes.

Check each learning against the current codebase, then check the set for overlap, supersession, and contradiction. A contradiction misleads actively, so it outranks individual staleness.

A knowledge-track learning sometimes points at a guidance file it names or links, such as a skill's SKILL.md, a runbook, or an instruction file. Compare only guidance the learning names. Never search the guidance layer for one.

Every investigation subagent's prompt carries that reference's three Subagent prompt clauses verbatim. Two are search tools and auto-memory. The third is this:

If the learning is knowledge-track and names or links a guidance file (a skill's SKILL.md, a runbook, a root instruction file), read that file and, when it states a different order or a contradictory rule for the same procedure, return both conflicting quotes plus which side current code follows — or that code witnesses neither. Read only guidance the learning names; do not search for one, and do not edit it.
