Skills Manager is a desktop application for installing, organizing, synchronizing, and tracking AI-agent skills across coding tools such as Claude Code, Codex, Cursor, Copilot, and Gemini CLI. It is for developers who use multiple coding agents and want their skills kept in one managed library.
Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00108 | $0.04396 |
| Opus 5 | $0.00054 | $0.02198 |
| Sonnet 5 | $0.00022 | $0.00879 |
| Haiku 4.5 | $0.00011 | $0.00440 |
Grade A, and why
manage-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 13d 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 — 355 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Before doing anything
-
Resolve the CLI first, then use the path it prints. Run this once (POSIX shell):
D="$HOME/.skills-manager/bin" B="$D/skills-manager-cli"; [ -e "$B" ] || B="$B.exe" # .exe on Windows if [ -s "$D/.version" ] && [ -x "$B" ]; then echo "$B" elif [ -s "$D/.version" ] || [ -e "$B" ]; then echo BRIDGE_BROKEN else P="$(command -v skills-manager-cli 2>/dev/null || true)" [ -x "$P" ] && echo "$P" fiSubstitute the printed path into every command below, wherever the examples write
$SM. Do not carry$SMas a shell variable: each command you run is a new shell, so an assignment made here is gone by the next one.The three outcomes:
- A path under
~/.skills-manager/bin— the desktop app published this copy, and the.versionstamp appears only after it has been verified, so it always matches the app the user is running. Use it. BRIDGE_BROKEN— something the app left behind is here but does not add up: an unstamped binary, or a stamp with no binary beside it. Either is what a copy that failed half-way leaves. Stop. Do not go looking for another CLI: that binary may predate a safety fix, and the machine has a desktop app whose version nothing here can match. Ask the user to open the Skills Manager app once, which republishes it.- A path from PATH — nothing was ever published here, so there is no stale copy to worry about: this is a CLI-only machine (a server install, a standalone download, a hand-built binary). Use it, but note it can be older than a desktop app if one is also installed.
If nothing is printed at all, this skill doesn't apply — fall back to find-skills, or tell the user to install Skills Manager.

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.

manage-skills is a skill published in the GitHub repository xingkongliang/skills-manager (4,667 stars, last pushed 4d ago), licensed MIT. It adds 108 tokens to every session and 4,396 once invoked, about $0.0005 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.
