Skillforge

Skillforge — the skill that creates skills

When a new capability is needed:

1. Check for duplicates. Read skills/_index.md. If a similar skill exists,

extend it instead of creating a new one.

1. Check memory. Read memory/semantic/LESSONS.md for related patterns.
2. Draft the skill. Create skills//SKILL.md with:

• YAML frontmatter (name, version, triggers, tools, preconditions, constraints)
• Plain-language instructions (destinations and fences, not driving directions)
• A self-rewrite hook at the bottom

1. Register it. Add an entry to skills/_index.md and append a JSON line

to skills/_manifest.jsonl.

1. Log it. Append a record to memory/semantic/DECISIONS.md explaining

why this skill was created.

What good skills look like

• State the destination ("verify tests pass before commit"), not the exact

command sequence.

• Include 2–3 examples of correct behavior when it clarifies intent.
• Include 1 example of a failure and what was learned from it.
• Keep the whole file under 100 lines.

Self-rewrite hook

After every 5 skills created, or on any failed creation:

1. Read the last 5 skillforge entries from episodic memory.
2. If better trigger patterns or constraint structures have emerged,

update this file and the template it implies.

1. Commit: skill-update: skillforge, .
