manage-skills

manage-skills is a skill for Claude Code, Codex from sutchan/Agent-Skills-Hub. It costs 108 tokens per session (4,396 once invoked), scanned A, a copy of manage-skills, MIT.

A management tool for a shared library of skills used by coding agents such as Claude Code, Codex, or Cursor. It installs, updates, removes, assigns, searches, and organizes those skills through a command-line program.

In plain words
What is it for?
It helps deploy or undeploy skills, update or remove them, manage presets and tags, and adopt skills that already exist in the library.
Why use it?
It gives teams one way to control which agent skills are available to each tool or agent instead of managing copies and assignments by hand.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; mentions Claude Code; mentions Codex.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/me/.claude/skills/db.

Good fit It helps deploy or undeploy skills, update or remove them, manage presets and tags, and adopt skills that already exist in the library.

Token cost

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.

Security

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 2d 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

  1. 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"
    fi
    

    Substitute the printed path into every command below, wherever the examples write $SM. Do not carry $SM as 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 .version stamp 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.

  2. Always pass --json when you parse output yourself. Pretty-printed output is for the user; JSON is for you. Errors include ok=false, a stable code, and message on stderr with a non-zero exit code.

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.
