In runtimes that honor that key, their descriptions stay out of the context window and the model cannot invoke them — a person types the command. In runtimes without the switch, the key is stripped at projection time and these remain ordinary advertised skills (see docs/contracts/codex-skill-api.md); the pointer below still tells a person which ones to run themselves. This skill **names** skills. It never invokes one. ## The roster | Skill | A person reaches for it when | |---|---| | `craft-goal` | authoring or linting a persistent goal prompt meant to drive many bounded experiments toward one outcome — a standing artifact a person owns, not this session's intent | | `learn` | mining a *collection* of durable verdicts for recurring evidence, after the critical path, on purpose | | `postmortem` | testing one retrospective causal question against verdict evidence that already exists | | `toil-mining` | mining supplied usage history for repeated operational work worth automating | What they share: each is off the critical path, each is started deliberately rather than inferred from a task, and nothing else in the repository reaches for any of them. ## When a model wants one Say which skill applies and why, and stop. Reproducing the skill's procedure by hand defeats the point of removing it from model reach — the command exists so a person decides the timing. ## Before adding a row Model invocation is...
