learning-extract

learning-extract is a skill for Claude Code from drivestream-lab/prayog-skills. It costs 80 tokens per session (1,304 once invoked), scanned A, original, MIT.

A skill that records reusable lessons after a development wave, such as a pull request review and human fixes. It classifies each lesson by whether it belongs in a specification, skill, test setup, or environment guidance.

In plain words
What is it for?
Use it after implementation and review to extract numbered lessons from repository changes, tickets, plans, tests, and prior reports.
Why use it?
It captures what went wrong or worked well while the evidence is still available, without requiring people to write lengthy learning reports.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

learning-extract scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Learning extract

Producer of structured learning after Pass-1 (implement) and human wave-acceptance / tip fixes. Gateflow may persist records in a global DB; this skill only writes a workspace artifact + handoff. /ground-spec still owns the wave Ground Report and §Contracts produced.

Do not require humans to write learning essays. Infer from repo + bind context. Ask taxonomy chips only when classification is ambiguous.

NON-NEGOTIABLE

  1. Resolve layout from .harness/profile.yaml or references/layout-defaults.md.
  2. Inspect the wave under test: bound ticket/initiative/wave/PR/run context when present; Pass-1 tip vs human-fix window (git log/diff); spec/plan/TASK rows; verify scripts / tests_readme; prior Ground Reports as needed.
  3. Emit learning items with closed taxonomy: SPEC, SKILL, HARNESS, optional ENV. One primary class per item. Prefer SPEC over SKILL when both fit.
  4. Assign stable ids L-01, L-02, … (see prayog-skills/references/id-conventions.md).
  5. Each item includes: summary, evidence (paths/commits), codify hint (suggested skill / spec area / harness home), status open | codified. Do not open auto-merge codify PRs.
  6. Write durable artifact {reports_dir}/Learning-Extract-{initiative}-W{N}.md with a human table and a fenced learning_extract: YAML block (machine payload). This file is PURGE at initiative closure (see artifact-write-contract).
  7. Empty items: [] only when there is no human-fix signal and the tip matches intent — state that rationale explicitly. If human fixes clearly exist and zero items → do not pass (use findings / fail-closed).
  8. Do not author the full Ground Report REQ matrix or §Contracts produced — that remains /ground-spec.
  9. Do not call Gateflow HTTP / DB as skill success. Worker ingest is the consumer (H6). Follow prayog-skills/references/forge-side-effects.md#content-producers for optional workspace publish.
  10. Ids / paths: prayog-skills/references/id-conventions.md, prayog-skills/references/artifact-write-contract.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
