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.

What it costs to keep this loaded
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 | $0.00055 | $0.00887 |
| Opus 5 | $0.00028 | $0.00443 |
| Sonnet 5 | $0.00011 | $0.00177 |
| Haiku 4.5 | $0.00006 | $0.00089 |
Grade A, and why
skill-creator 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 10d 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Creator
Build skills that behave like “mini senior engineers”: trigger correctly, run deterministically, and leave resumable artifacts on disk.
What good looks like (Ship Faster standard)
SKILL.md: short and triggerable (routing + safety + I/O + output contract). Avoid long tutorials here.references/: deep docs loaded only when needed (progressive disclosure). Link directly fromSKILL.md.scripts/: deterministic helpers for repetitive/fragile work (prefer this over re-writing code in chat).assets/: templates or files to copy (not meant to be loaded into context).
Deep guidance:
- Progressive disclosure + authoring principles:
references/skill-design-principles.md - Workflow structure patterns:
workflows.md - Output templates/patterns:
output-patterns.md
Creation flow (recommended)
- Collect trigger examples (real user phrases that should activate the skill).
- Define the I/O contract (paths only) + required artifacts:
- What files does the skill read?
- What files must it write (plans, evidence, summaries)?
- Implement reusable resources first:
- add
scripts/for deterministic steps - add
references/for heavy documentation - add
assets/for templates / boilerplate
- add
- Write
SKILL.mdlast:- frontmatter
descriptionshould include trigger phrases - body should be short and link out to the resources above
- frontmatter
- Validate + package (optional) using the scripts below.
Scripts
All scripts live in scripts/ in this skill folder.
Initialize a new skill folder
python scripts/init_skill.py <skill-name> --path <output-directory>
Validate a skill (frontmatter + basic conventions)
python scripts/quick_validate.py /path/to/<skill-name>
Sync catalogs/assets (manifest, skills-map, docs catalog)
python scripts/sync_catalog.py
Lint skills (compat + quality gates)
What ships with it
10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

skill-creator is a skill published in the GitHub repository Heyvhuang/ship-faster (339 stars, last pushed 25d ago), licensed MIT. It adds 55 tokens to every session and 887 once invoked, about $0.0003 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 2026-08-30.
