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 | $0.00046 | $0.00433 |
| Opus 5 | $0.00023 | $0.00217 |
| Sonnet 5 | $0.00009 | $0.00087 |
| Haiku 4.5 | $0.00005 | $0.00043 |
Grade B, and why
sync-skills scanned grade B with 1 finding 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 5d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

sync-skills
Claude Codeプラグインのスキルを .agents/skills/ にsymlinkし、Codexから発見可能にする。
When to Use
- プラグイン更新後
- 新しいプロジェクトでCodexからスキルを使いたい時
.agents/skills/のsymlinkが壊れた時
Workflow
Step 1: Read installed_plugins.json
cat ~/.claude/plugins/installed_plugins.json | jq -r '
.plugins | to_entries[] | .value[] |
[.scope, .installPath, (.projectPath // "")] | @tsv
'
各エントリのscope/installPath/projectPathを取得。
Step 2: Filter plugins
scope=user: 常に対象scope=local: projectPathが現在のプロジェクトと一致する場合のみ
Step 3: Create symlinks
対象pluginごとに installPath/skills/ 配下のディレクトリを .agents/skills/ にsymlink。
mkdir -p .agents/skills
ln -s <installPath>/skills/<skill-name> .agents/skills/<skill-name>
- raw skill名を使用（prefix無し）
- 壊れたsymlink: 削除して再作成
- 正しいsymlink: スキップ
- 衝突: ユーザーに確認（上書き or スキップ）
Step 4: Report
作成/スキップ/衝突の結果を報告。

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.

sync-skills is a skill published in the GitHub repository morodomi/dev-crew (1 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 433 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

i-have-adhd
Shape output for a reader with ADHD: lead with the next action, number multi-step work, restate state across turns, suppress tangents, give specific time estimates, make wins visible. Invoke with /i-have-adhd; stays on until "stop adhd mode".
test-driven-development
Enforces TDD discipline with RED-GREEN-REFACTOR cycle. Use when writing new features, fixing bugs, or refactoring code. Ensures tests genuinely verify behavior.
testing-principles
Language-agnostic testing principles including TDD, test quality, coverage standards, and test design patterns. Use when writing tests, designing test strategies, or reviewing test quality.
writing-plans
Use when you have a spec or requirements for a multi-step task, before touching code.
x-qdev
A compact development workflow for a small, clearly defined code change. It keeps the requirement, initially failing tests, implementation, and real verification results in one task document, following TDD, or test-driven development.
sitrep-panel
Keep a live local HTML report updated as you work on a task — a status board, a running "what's happening now" narrative, screenshots, and a newest-first log — served on localhost so the user can watch progress in a browser tab instead of reading the transcript. Use when the user invokes /sitrep-panel, asks for a…
