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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 15 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
- medium Agent Snooping · line 81 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00067 | $0.01788 |
| Opus 5 | $0.00034 | $0.00894 |
| Sonnet 5 | $0.00013 | $0.00358 |
| Haiku 4.5 | $0.00007 | $0.00179 |
Grade A, and why
skill-maker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/as:skill-maker — Scaffold a New Skill
Harness note: use
/as:<skill>on Claude Code and$<skill>on Codex. Resolve<skill-root>as the directory containing this loadedSKILL.mdand<plugin-root>as the plugin root that containsskills/, and use equivalent native tools when host tool names differ.
You turn a described procedure into a working skill: a directory with a SKILL.md and a README.md that follows this repo's conventions. Input is the user's request; output is a card Codex or Claude Code can follow.
Usage
/as:skill-maker a skill that turns raw site photos into a numbered photo log
/as:skill-maker package our submittal-review checklist as a slash command
/as:skill-maker <any procedure worth repeating>
Hard rule: no routine interview
Derive everything — name, description, tools, steps — from the request. Do not ask routine setup questions. Ask exactly one question only when the skill's purpose is genuinely indecipherable, the user requests a global skill without explicitly authorizing the global target, or an existing target would have to be updated. Otherwise make the reasonable call and note it when presenting the result.
Anatomy of what you're producing
A skill is a procedure card. Four load-bearing parts:
| Part | Job |
|---|---|
name |
Kebab-case, matches the directory, becomes the skill command |
description |
The trigger, not a label — how the active harness knows to reach for the card unasked |
allowed-tools |
Claude Code's optional permission hint; omit for Codex-only skills |
| Steps | The procedure itself: numbered, concrete, in execution order |
Step 1 — Scaffold from the template
Resolve SKILL.example.md and README.md from the non-installable bundled template at <plugin-root>/assets/skill-maker-template/, adapting SKILL.example.md into the target's SKILL.md and changing every line that describes the example. This skill's output is files on disk, not a proposal: for a new, safely resolved target, state the exact path and write both SKILL.md and README.md without presenting a draft first. Do not promise that a permission prompt will appear; permission behavior depends on the active Claude Code settings. If the bundled template can't be located, scaffold from the Anatomy table above.
What ships with it
2 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-maker is a skill published in the GitHub repository AlpacaLabsLLC/skills-for-architects (353 stars, last pushed 9d ago), licensed MIT. It adds 67 tokens to every session and 1,788 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.
