Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00173 | $0.01640 |
| Opus 5 | $0.00086 | $0.00820 |
| Sonnet 5 | $0.00035 | $0.00328 |
| Haiku 4.5 | $0.00017 | $0.00164 |
Grade A, and why
shipjaw-build scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
shipjaw-build
Bootstrap-only. Turns a build-ready product prompt into a scaffolded
TypeScript site and a committed documentation/ map. Later sessions use
shipjaw-ask. Prefer shipjaw-prompt first when the idea is still vague.
Slash-preferred (disable-model-invocation) — avoid ambient auto-scaffold.
Operating principles: references/skill-principles.md (1–18) — open
only if a principle conflict arises; hard rules below are enough for most
runs.
Anti-triggers (stop — don't run bootstrap)
documentation/knowledge-base/already exists →shipjaw-ask- Existing app code without Shipjaw KB →
shipjaw-adopt(do not re-scaffold in place) - Idea is still vague / user wants help wording the product →
shipjaw-promptfirst - Single-file cosmetic / copy tweak with no product build
- Non-TypeScript codebase
- User only wants framework tutorial text (point at official docs)
Hard rules (never negotiable)
- Typing —
strict: true. Noany.unknownonly at untyped entry points, narrowed via zod/type guard. →code-standards.md - File size — hard cap 500 lines; plan split ~300.
- Architecture — canonical tree in
project-structure.md(including types / constants / helpers, ports, composition root, thin adapters, error→UI/HTTP map). Contracts consumer updates only ifpackages/contracts/exists. No grab-baglib/utils.tsor layer barrels. - Tests — Vitest for domain/application; Playwright + axe +
keyboard/focus smoke for critical flows. Bug fix ⇒ regression test;
never weaken tests to green. →
testing-and-ci.md·regression-and-business-rules.md - Security — secrets out of git; authz in
application/; actions re-check session; middleware; CSP via scaffoldnext.config.ts. - Documentation — committed
documentation/. No app code beforeINDEX.md+ phase-01. Stamp viascripts/stamp-provenance.sh. - Verify — one gate/phase; stop after 2 failed attempts. On the
second failure read
references/gate-failure-modes.mdbefore one last focused fix; then ask the human if still red. - KB current — update before done; state not only in chat.
- UI floor — when shipping visible UI, obey
references/design-constraints.md(+ product design-brief).

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

shipjaw-build is a skill published in the GitHub repository XyDisorder/shipjaw (2 stars, last pushed 3d ago), licensed MIT. It adds 173 tokens to every session and 1,640 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
