What it does

Skill Inventory is an agent skill from hoangsonww/Claude-Code-Agent-Monitor. Inventory the installed skills and which plugins contribute them, then flag overlap with the user's own skills — read through the Agent Monitor Config Explorer API. Reads /api/cc-config/skills and /api/cc-config/plugins. Use when managing skills: deduping, deciding what to keep, or tracing a skill back to the plugin that ships it.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

The repository describes itself as: 🚀 A real-time monitoring dashboard for Claude Code & Codex, built with SQLite3, Node.js, Express, React, Vite, TailwindCSS, & WebSockets. It tracks sessions, agent activity… The licence is MIT.

When your agent uses it

  • Managing skills: deduping
  • Deciding what to keep
  • Tracing a skill back to the plugin that ships it

Example prompts

  • “/skill-inventory”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. User & project skills
  2. Plugin-contributed skills
  3. Overlap & duplication
  4. Disabled / orphaned plugins

What it can do on your machine

Read from SKILL.md and the folder at commit 1a10d68. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skill Inventory loads about 745 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 340 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~745

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Inventory the installed skills and which plugins contribute them, then flag overlap with the user's own skills — read through the Agent Monitor Config Explorer API. Reads /api/cc-config/skills and /api/cc-config/plugins. Use when managing skills: deduping, deciding what to keep, or tracing a skill back to the plugin that ships it.

Skill Inventory

Map every skill available to the user — both their own (user/project scope) and the ones contributed by installed plugins — read through the Agent Monitor dashboard at http://localhost:4820.

Input

The user provides: $ARGUMENTS

This may be:

  • empty — inventory all skills (default).
  • a skill name fragment — focus on skills whose name matches.
  • a plugin name — show only the skills that plugin contributes.

Data Sources

EndpointReturns
GET /api/cc-config/skills{ items:[{ scope:"user"|"project", name, path, file, size, mtime, frontmatter, preview }] } — the user's own skill directories
GET /api/cc-config/plugins{ manifestPath, manifestExists, plugins:[{ key, name, marketplace, scope, version, enabled, installPath, contributes:{ skills, agents, commands, outputStyles, hooks } }] }

Report Sections

1. User & project skills

From /skills, list each skill with scope, name, size (KB), and frontmatter.description (or the start of preview). Separate user-scope from project-scope skills.

2. Plugin-contributed skills

From /plugins, list each plugin with enabled state and its contributes.skills count. Note that /skills reports only the user's own skill dirs — plugin skills are counted via contributes, so reconcile: total available skills ≈ user skills + Σ enabled-plugin contributes.skills.

3. Overlap & duplication

Flag where a plugin name or a plugin's contributed-skill domain overlaps with a user-authored skill of the same name or purpose (compare against frontmatter.description from /skills). Recommend keeping one source of truth — prefer the plugin version if it is maintained upstream, or the user version if it is customized.

4. Disabled / orphaned plugins

Flag plugins with enabled: false (their skills are inert) and any whose installPathExists is false (manifest references a missing install) — these are dead weight to clean up via the Claude Code plugin manager.

Output

  • Section 1 as a table (Scope | Name | Size | Description).
  • Section 2 as a table (Plugin | Enabled | Skills | Agents | Commands).
  • A reconciliation line: user skills + plugin skills = total available.
  • Cite only fields the API returned — never fabricate skills or counts.
  • Note: plugins are read-only via the Config Explorer; manage them with the Claude Code plugin commands, not this dashboard.
  • If the dashboard is unreachable at http://localhost:4820, say so and tell the user to start it with npm start from the repo root.
