/learnskill <thing-name> [--invocable|--internal] [--type atomic|orchestrator]
Forge-native graduation orchestrator. Built 2026-05-02. Turns the "I just hacked together this thing" moment into a documented, idempotent, registered tool with one slash command.
What it does¶
Eight-step procedure:
1. Capture intent from the just-completed task
2. Classify (atomic vs orchestrator, invocable vs internal helper)
3. Generate canonical script at forge/scripts/forge_<name>.{py,sh} with idempotency + fail-loud structure
4. Write SKILL.md if user-invocable (matches /research, /strategy patterns)
5. Write topic file at forge/memory/general/reference_<name>.md
6. Add one-line MEMORY.md index entry under the right section
7. Smoke test (happy path + bad input + idempotency check)
8. Report + offer 30-day /followup to verify usage
When it fires¶
The graduate hacks to skills feedback memory defines the trigger signals: seen-twice rule, obvious reuse, external-tool wrapper, format conversion, API call boilerplate, multi-step CLI chain, or Justin flagging it.
Output contract¶
Every graduated tool produces:
- Canonical script (chmod 755, idempotent, fail-loud, no em dashes, snake_case naming per FORGE-DOCTRINE.md Section 4)
- SKILL.md (only if --invocable)
- Topic file (always, with mkdocs URL)
- MEMORY.md index entry (one line, under correct section)
- Successful smoke test
Halts if any step fails. No half-graduations.
When NOT to use¶
- Truly one-off work (renaming three files, fixing a typo)
- Re-running an existing forge script with different args (use
/followupto schedule it) - Heavyweight skill development needing evals + iteration (use
skill-creatorplugin instead) - Editing an existing forge tool (edit in place, update topic file)
Cost model¶
Subscription quota only. The graduation work happens in the current session, no worker spawn needed. Per cost-aware automation defaults.
