SKILL
FORGE

The meta-skill that forges skills. Auto-discover workflows, create evaluated skills, optimize triggers.

Three gaps in the skill lifecycle

01 Don't know when to create a skill Auto-detect complex tasks, proactively ask
02 Don't know if a skill is well-written 5-dimension evaluator, threshold before save
03 Don't know if it will actually trigger Eval-driven description optimization

From raw workflow to tempered skill

Ore /scan Discover opportunities in your codebase
Heat /create Research patterns, draft the skill
Strike eval 5-dim scoring, reject below 6/8
Temper /improve Patch content, optimize triggers
Blade SKILL.md Production skill, registry tracked

Four verbs, one workflow

claude-code
$ /scan [prompt]
Scan project for skill opportunities.
$ /create <prompt>
Create skill from prompt. Name auto-derived.
$ /improve <prompt>
Iterate skill from prompt. Target matched from registry.
$ /list
Print skill registry — versions, scores, trigger rates.

Principled, not magical

Dual-file isolation
Injection-proof by design
External content lands in low-trust skill_insights.md. Only validated patterns promote to the high-trust draft that hooks inject.
Attention anchoring
Hooks keep the goal in focus
UserPromptSubmit and PreToolUse hooks re-inject the draft header every turn. Context overflows can't erase the mission.
Session catchup
Nothing slips through the cracks
Missed a complex workflow yesterday? SessionStart parses previous JSONL, surfaces uncaptured 5+ tool-call tasks.
Eval-driven triggers
Description is a separate problem
20-case trigger evaluations, 60/40 train/test split, up to 5 optimization rounds. Your skill fires when it should.

Start forging.

Then run /scan to discover your first opportunities.
