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 | $0.00030 | $0.01833 |
| Opus 5 | $0.00015 | $0.00916 |
| Sonnet 5 | $0.00006 | $0.00367 |
| Haiku 4.5 | $0.00003 | $0.00183 |
Grade A, and why
skill-stocktake scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Enumerates other installed skillslowAgent snooping
Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.
(Project dir is auto-detected from `$PWD/.claude/skills`; pass it explicitly only if needed) Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts
The opening of the file, as written. The whole thing — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.
skill-stocktake
Slash command (/skill-stocktake) that audits all Claude skills and commands using a quality checklist + AI holistic judgment. Supports two modes: Quick Scan for recently changed skills, and Full Stocktake for a complete review.
Scope
The command targets the following paths relative to the directory where it is invoked:
| Path | Description |
|---|---|
~/.claude/skills/ |
Global skills (all projects) |
{cwd}/.claude/skills/ |
Project-level skills (if the directory exists) |
At the start of Phase 1, the command explicitly lists which paths were found and scanned.
Targeting a specific project
To include project-level skills, run from that project's root directory:
cd ~/path/to/my-project
/skill-stocktake
If the project has no .claude/skills/ directory, only global skills and commands are evaluated.
Modes
| Mode | Trigger | Duration |
|---|---|---|
| Quick Scan | results.json exists (default) |
5–10 min |
| Full Stocktake | results.json absent, or /skill-stocktake full |
20–30 min |
Results cache: ~/.claude/skills/skill-stocktake/results.json
Quick Scan Flow
Re-evaluate only skills that have changed since the last run (5–10 min).
- Read
~/.claude/skills/skill-stocktake/results.json - Run:
bash ~/.claude/skills/skill-stocktake/scripts/quick-diff.sh \ ~/.claude/skills/skill-stocktake/results.json(Project dir is auto-detected from$PWD/.claude/skills; pass it explicitly only if needed) - If output is
[]: report "No changes since last run." and stop - Re-evaluate only those changed files using the same Phase 2 criteria
- Carry forward unchanged skills from previous results
- Output only the diff
- Run:
bash ~/.claude/skills/skill-stocktake/scripts/save-results.sh \ ~/.claude/skills/skill-stocktake/results.json <<< "$EVAL_RESULTS"
Full Stocktake Flow
Phase 1 — Inventory
Run: bash ~/.claude/skills/skill-stocktake/scripts/scan.sh
What ships with it
3 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-stocktake is a skill published in the GitHub repository x-cmd/skill (26 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 1,833 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
