/skill-builder — Scaffold or absorb a new SKILL.md

Materializes a new skill against the unified template at references/skill-template.md (extracted from anthropics/financial-services). Runs skill-auditor on the new skill as a self-check before declaring success.

If unsure whether the work should be a skill, a Workflow, or an NTM swarm, run /automation-shape-routing first — it is the front door that decides the shape and hands off to the right builder.

⚠️ Critical Constraints

Template is canonical. All four modes produce SKILL.md files conforming to references/skill-template.md. Do not invent ad-hoc structures. Why: skill-auditor validates against this template; drift creates auditor false-fails.
Self-audit is mandatory. After every successful build, the build script invokes /skill-auditor against the new skill directory. A FAIL verdict aborts the build. Why: PR-002 (external validation gate) — the builder must not declare its own work complete.
Codex parity is day-1, not later. from-scratch, from-template, and absorb-external modes must produce both skills/<name>/SKILL.md AND skills-codex/<name>/SKILL.md + skills-codex/<name>/prompt.md. Why: finding 2026-05-03-codex-skill-shape-is-dual-file — codex SKILL.md uses slim frontmatter (no skill_api_version); prompt.md is mandatory; audit-codex-parity.sh is a content scanner that won't catch frontmatter drift.
250-line ceiling on new SKILL.md. Use references/ for overflow. Why: finding f-2026-05-01-025 — every Skill() invocation reloads 5-15KB; multi-lifecycle sessions compound to 150-200KB+ pure scaffolding.
Clean-room factory inputs only. When using lessons learned from external corpora, read [references/agentops-skill-factory.md](references/agentops-skill-factory.md) and use only AgentOps-owned summaries, scripts, and rubrics. Why: productization must improve structure without copying protected third-party skill content.

Modes

| Mode | Status | Description | |------|--------|-------------| | from-scratch | stable | Interactive scaffold from canonical template. Produces full skill skeleton + scripts/validate.sh + codex parity. | | from-template | stable | --like <existing-skill> copies structure from a sibling skill, swaps domain-specific sections. | | absorb-external | stable | Reads external SKILL.md (e.g., from ~/dev/financial-services/.../<skill>/SKILL.md), wraps in AgentOps frontmatter, invokes /converter for codex parity. | | from-pattern | alpha (passthrough) | Delegates to ao flywheel close-loop. Outputs land at .agents/knowledge/promoted/ per flywheel rules — they are NOT yet shaped as SKILL.md drafts. v2 will add skill-specific synthesis. Use from-scratch or absorb-external for SKILL.md output today. |

Workflow

Phase 1: Mode dispatch

scripts/build.sh reads $1 and routes:

build.sh from-scratch <new-skill-name>          # → init.sh --interactive
build.sh from-template <new-skill-name> --like council
build.sh absorb-external <new-skill-name> --from /path/to/SKILL.md
build.sh from-pattern                            # → ao flywheel close-loop

Checkpoint: Confirm with user the new skill's metadata.tier and metadata.dependencies before generation.

Phase 2: Materialize from template

scripts/init.sh reads references/skill-template.md (the canonical template section) and renders a SKILL.md skeleton with frontmatter pre-filled. For from-template, structure is copied from the source skill; section bodies are blanked and replaced with template stubs.

For absorb-external, the external SKILL.md's content (Constraints / Workflow / Output / Quality sections) is preserved verbatim where possible; AgentOps' structured frontmatter is added on top; the external description is reformatted to satisfy description-has-triggers.

Checkpoint: /heal-skill --check skills/<new-name> returns clean.

Phase 3: Codex parity

scripts/init.sh invokes /converter skills/<new-name> codex to produce skills-codex/<new-name>/{SKILL.md,prompt.md}. Then trims skill_api_version from the codex SKILL.md (converter may preserve it). Asserts prompt.md exists.

Checkpoint: bash scripts/audit-codex-parity.sh returns clean AND grep -q "^skill_api_version:" skills-codex/<name>/SKILL.md returns nothing.

Phase 4: Self-audit

The build script tail invokes /skill-auditor on skills/<new-name>. WARN is acceptable for v1 skills (e.g., experimental stability). FAIL aborts.

Checkpoint: audit_pass=true in build report.

Phase 5: Factory score overlay

For AgentOps skill upgrades, use the productization score as a patch selector, not as a replacement for skill-auditor:

python3 skills/skill-auditor/scripts/score_agentops_skill.py skills/<name> --markdown

Choose the smallest patch that improves the score while preserving the canonical template and Codex parity constraints.

Output Specification

Format: JSON conforming to schemas/build-report.json written to stdout; markdown audit report written to .agents/audits/<skill>-build.md.

Files created (from-scratch mode):

skills/<name>/
├── SKILL.md                         (≤250 lines, full template spine)
├── scripts/
│   └── validate.sh                  (self-validation per AgentOps convention)
└── references/                      (only if expected to exceed 400 lines)
skills-codex/<name>/
├── SKILL.md                         (slim frontmatter — no skill_api_version)
└── prompt.md                        (~10-20 line Execution Profile)

Quality Rubric

[ ] All four modes produce skills that pass skill-auditor PASS or WARN (not FAIL)
[ ] Codex parity files exist and pass slim-frontmatter check
[ ] No SKILL.md exceeds 250 lines (overflow goes to references/)
[ ] Build report JSON validates against schemas/build-report.json
[ ] from-pattern mode prominently marked alpha/passthrough in user output

Examples

Create a new skill from scratch:

/skill-builder from-scratch hello-world
# → interactive prompt: tier? deps? primary deliverable?
# → writes skills/hello-world/SKILL.md + skills-codex/hello-world/{SKILL.md,prompt.md}
# → runs /skill-auditor on the new skill

Clone structure from an existing skill:

/skill-builder from-template my-new-skill --like council
# → mirrors council's section spine; substitutes new metadata

Absorb a skill from anthropics/financial-services:

/skill-builder absorb-external dcf-helper \
  --from ~/dev/financial-services/plugins/vertical-plugins/financial-analysis/skills/dcf-model/SKILL.md
# → preserves Constraints/Workflow/Output content, wraps in AgentOps frontmatter

Troubleshooting

| Problem | Cause | Solution | |---------|-------|----------| | Self-audit FAIL | Generated SKILL.md missing required Pass-2 check | Re-run with --verbose; inspect which check failed; usually output-spec-explicit or trigger-clarity | | Codex parity drift | /converter preserved skill_api_version | init.sh runs sed -i '/^skill_api_version:/d' skills-codex/<name>/SKILL.md; verify with grep | | SKILL.md > 250 lines | Mode generated too much inline content | Move section bodies to references/<topic>.md; reference inline as [text](references/<topic>.md) | | from-pattern produces no SKILL.md | Expected behavior — passthrough only in v1 | Use from-scratch or absorb-external if you need a SKILL.md draft |
