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: 3 findings, up to medium
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 →

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 | $0.00045 | $0.02099 |
| Opus 5.5 | $0.00018 | $0.00840 |
| Sonnet 5.5 | $0.00009 | $0.00420 |
| Haiku 4.5 | $0.00005 | $0.00210 |
Grade A, and why
create-project-skills 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Project Skills
Generates one skill per detected convention area in the project's skill directory so future Claude or Codex sessions auto-load them when working in the repo.
Task Tracking
At the start, use TaskCreate to create a task for each phase:
- Survey codebase
- Extract patterns in parallel
- Evaluate patterns
- Propose skill list
- Run
/write-skillskill
Step 1: Survey Codebase
If $ARGUMENTS specifies paths, scope the scan to those paths; otherwise scan the whole repository.
Build the extraction context:
- Detect primary languages and frameworks from manifest files (
package.json,Cargo.toml,pyproject.toml,go.mod,Package.swift,pom.xml,Gemfile, and others appropriate to the stack). - Map the top-level source directory structure and note test directory conventions.
- Read
CLAUDE.md,.claude/rules/,AGENTS.md, and any.cursor/rulesor.cursorrules. Note the conventions already documented there. The generated skills must not duplicate them. - Determine the target skill directory:
- Check candidate paths
.claude/skills/(Claude Code),.agents/skills/(Codex), and a top-levelskills/directory (match case-insensitively soSkills/or similar non-standard casing is detected too). Resolve symlinks so co-linked paths are treated as one logical location. - Use
AskUserQuestionto confirm where generated skills should live. List each distinct resolved location as an option, noting any symlink alias in the option description. If.claude/skills/is not among the detected locations, include it as a default option. The auto-added "Other" option lets users specify a custom path such as a project-specific directory.
- Check candidate paths
- In the chosen target directory, list existing skills. For each, record the skill name, the description from SKILL.md frontmatter, and the first
##section heading from the body. These signals feed rename-conflict detection in Step 3.
Output a short text summary of detected stack, top-level layout, chosen target directory, and existing skills before moving on.
What ships with it
1 file 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.

create-project-skills is a skill published in the GitHub repository tobihagemann/turbo (420 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 2,099 once invoked, about $0.0002 per session on Opus 5.5. 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.
