# skill-forge

Generate production-ready AbsolutelySkilled skills from any source - GitHub repos,
documentation URLs, or pure domain knowledge. This is the bootstrapping tool for the
registry.

A skill is a **folder, not a file**. Think of the entire file system as context
engineering and progressive disclosure. SKILL.md is the entry point, but scripts,
references, assets, and data files are where the real power lives.

---

## Slash command

```
/skill-forge <url-or-topic>
```

---

## Setup

On first run, check for `${CLAUDE_PLUGIN_DATA}/forge-config.json`. If it doesn't
exist, ask the user these questions (use AskUserQuestion with multiple choice):

1. **Default output directory** - `skills/` (registry PR) or custom path?
2. **Auto-propagate recommendations?** - yes/no (Phase 7)
3. **Skill type preference** - code-heavy, knowledge-heavy, or balanced?

Store answers in `${CLAUDE_PLUGIN_DATA}/forge-config.json`. Read this config at the
start of every forge session.

---

## Forge history

After every successful forge, append an entry to `${CLAUDE_PLUGIN_DATA}/forge-log.jsonl`:

```json
{"skill": "api-design", "type": "domain", "date": "2025-01-15", "lines": 245, "refs": 3, "evals": 12}
```

Read this log at the start of each session. It helps you:
- Avoid creating duplicate skills
- Reference patterns from previously forged skills
- Track which categories are over/under-represented

---

## Step 0 - Detect input type

- **URL input** (starts with `http`, `github.com`, or looks like a domain) -> Phase 1A
- **Domain topic** (a word or phrase) -> Phase 1B
- **Ambiguous** -> ask the user

---

## Phase 1A - Research (URL-based)

The quality of the skill is entirely determined by the depth of research here.
Do not write a single line of SKILL.md until research is complete.

### Crawl order (priority high to low)

```
1. /llms.txt or /llms-full.txt   - AI-readable doc map (gold)
2. README.md                      - overview, install, quickstart
3. /docs/                         - main documentation index
4. API reference                  - endpoints, params, errors
5. Guides / tutorials             - real-world usage patterns
6. Changelog                      - breaking changes, versioning
```

Stop fetching a category once you have good coverage - 5 pages that give the full
picture beats 20 pages of marginal detail.

### Discovery questions

While crawling, answer these six questions - they form your mental model:

1. What does this tool do? (1 sentence)
2. Who uses it?
3. What are the 5-10 most common agent tasks?
4. What are the gotchas? (auth, rate limits, pagination, SDK quirks)
5. What's the install/auth story?
6. Are there sub-domains needing separate references/ files?

### Uncertainty handling

Flag ambiguous or missing detail inline - never skip a section:

```markdown
<!-- VERIFY: Could not confirm from official docs. Source: https://... -->
```

Aim for < 5 flags. More than 5 means you haven't crawled enough.

---

## Phase 1B - Brainstorm Discovery (domain-based)

For domain topics, run an interactive brainstorm with the user.

**HARD GATE:** Do NOT write any SKILL.md until the user approves the scope.
"TypeScript" could mean best practices, migration guides, or project setup.

Ask these questions **one at a time** (use multiple choice when possible):

1. Target audience?
2. Scope? (offer 2-3 options with your recommendation)
3. Top 5-8 things an agent should know?
4. Common mistakes to prevent?
5. Sub-domains needing their own references/ files?
6. Output format? (code, prose, templates, checklists, or mix)

Present a proposed outline. Wait for approval before proceeding.

---

## Phase 2 - Write SKILL.md

Read `references/frontmatter-schema.md` for YAML fields and
`references/body-structure-template.md` for the markdown scaffold.

### Key principles for writing

**Focus on what pushes Claude out of its defaults.** Claude already knows how to
write markdown and structure content. Your skill should teach it things it would
get wrong without the skill - the gotchas, the non-obvious patterns, the domain
quirks that trip up even experienced developers.

**The description field is a trigger, not a summary.** Claude scans every skill
description at session start to decide which to activate. Write it as a
when-to-trigger condition with specific tool names, synonyms, and action verbs.

**Build the Gotchas section first.** This is the highest-signal content in any
skill. Start with 3-5 known failure points and expect the section to grow over
time as users hit new edge cases. Put gotchas inline next to the relevant task,
not in a separate section users might skip.

**Use progressive disclosure.** SKILL.md should be the entry point, not the
encyclopedia. Point to references/ files for deep detail. Tell Claude what files
exist and when to read them - it will load them on demand.

**Don't railroad.** Give Claude the what and why, not rigid step-by-step
procedures. Skills get reused across many contexts - overly prescriptive
instructions break in unexpected situations. Prefer guidelines over rules.

### After writing

Run `scripts/validate-skill.sh <path-to-skill-dir>` to check structure and
catch common issues before finalizing.

Always append the shared footer from `references/skill-footer.md` as the very
last section.

---

## Phase 3 - Write references/

Create a references/ file when:
- A topic has more than ~10 API endpoints
- A topic needs its own mental model (e.g. Stripe Connect vs Payments)
- Including it inline would push SKILL.md past 300 lines

Every references file must start with:

```markdown
<!-- Part of the <ToolName> AbsolutelySkilled skill. Load this file when
     working with <topic>. -->
```

Consider adding these non-markdown files when they'd help the agent:
- **Scripts** (`scripts/`) - validation, setup, code generation helpers
- **Templates** (`assets/`) - output templates the agent can copy and fill
- **Data** (`data/`) - lookup tables, enum lists, config schemas as JSON/YAML
- **Examples** (`examples/`) - complete working code the agent can reference

---

## Phase 4 - Write evals.json

Read `references/evals-schema.md` for the JSON schema and worked examples.

Write 10-15 evals covering: trigger tests (2-3), core tasks (4-5),
gotcha/edge cases (2-3), anti-hallucination (1-2), references load (1).

---

## Phase 5 - Write sources.yaml

Read `references/sources-schema.md` for the YAML schema.
Only for URL-based skills. Domain skills can omit this if purely from
training knowledge and user input.

---

## Phase 6 - Output

Write to `skills/<skill-name>/` (or the path from forge-config.json).

```
skills/<skill-name>/
  SKILL.md
  sources.yaml       (optional for domain skills)
  evals.json
  references/        (if needed)
  scripts/           (if needed)
  assets/            (if needed)
```

Print a summary and append to forge-log.jsonl.

---

## Phase 7 - Propagate recommended_skills

If auto-propagate is enabled in config (or always for new skills):

1. Read the new skill's `recommended_skills`
2. For each companion, check if it reciprocally lists the new skill
3. Add if the companion has < 5 recommendations and the relationship is genuine
4. Never remove existing recommendations without clear reason
5. Print which skills were updated in the summary

---

## Gotchas

These are the most common failure points when forging skills. Update this list
as new patterns emerge.

1. **Description too vague** - "A skill for testing" will never trigger. Include
   the tool name, 3-5 task types, and common synonyms. This is the #1 reason
   skills don't activate.

2. **Stuffing everything into SKILL.md** - If you're past 300 lines, you're
   doing it wrong. Move detail to references/ files. The agent reads them on
   demand - trust the progressive disclosure.

3. **Stating what Claude already knows** - Don't explain how REST APIs work or
   what JSON is. Focus on the non-obvious: auth quirks, deprecated methods,
   version differences, naming inconsistencies.

4. **No gotchas in the generated skill** - Every skill should have inline
   gotchas next to relevant tasks. "This method requires amount in cents, not
   dollars" saves more time than 50 lines of API docs.

5. **Railroading the agent** - "Always do X, then Y, then Z" breaks when the
   context doesn't match. Give guidelines, not rigid procedures. The agent needs
   flexibility to adapt.

6. **Forgetting the folder is the skill** - SKILL.md is just the entry point.
   Scripts, templates, data files, and examples are what make a skill genuinely
   useful. A data-science skill with `fetch_events.py` beats one with 200 lines
   explaining how to query your event source.

7. **Not checking for duplicates** - Always read `references/skill-registry.md`
   before forging. Redundant skills fragment the registry.

8. **Generic domain advice** - For knowledge skills, "write good copy" is
   useless. "Use the PAS framework: Problem, Agitate, Solution" is actionable.
   Every piece of advice should be specific enough to act on immediately.

## Quality checklist

- [ ] Description is a trigger condition (tool name + 3-5 task types + synonyms)
- [ ] Gotchas are present and inline next to relevant tasks
- [ ] SKILL.md under 300 lines (detail moved to references/)
- [ ] No obvious-to-Claude content (how markdown works, what APIs are, etc.)
- [ ] Progressive disclosure: references/ files listed with when-to-read guidance
- [ ] For URL skills: sources.yaml has only official doc URLs
- [ ] For domain skills: user approved scope before writing
- [ ] Evals cover all 5 categories
- [ ] Flagged items use `<!-- VERIFY: -->` format
- [ ] Footer appended from `references/skill-footer.md`
- [ ] Forge history log updated
- [ ] Recommendations propagated (Phase 7)

---

## References

Load these files only when you need them for the current phase:

- `references/frontmatter-schema.md` - YAML template + category taxonomy (Phase 2)
- `references/body-structure-template.md` - Markdown body scaffold (Phase 2)
- `references/evals-schema.md` - JSON schema + worked example (Phase 4)
- `references/sources-schema.md` - YAML schema for sources (Phase 5)
- `references/worked-example.md` - Resend end-to-end example (first-time orientation)
- `references/skill-registry.md` - Full catalog of existing skills (duplicate check)
- `scripts/validate-skill.sh` - Structural validation for generated skills (Phase 2)
