What it does
Reviewing Agent Definitions is an agent skill from bitwarden/ai-plugins, published by the product's own GitHub organization. Reviews Claude Code agent definition files for tool-access security, triggering quality, and system prompt clarity. Use when reviewing changes to agents/<name.md or agents/<name/AGENT.md, whether under .claude/agents/ or inside a plugin. Flags over-privileged tool grants, unjustified Bash access, descriptions with no activation triggers, and system prompts too vague to act on. Also use when asked to audit a subagent's tool access or check whether an agent will trigger. Normally reached through…
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering Prompt engineering and Subagents. It works with Bash. The repository describes itself as: AI plugin marketplace.
When your agent uses it
- Reviewing changes to agents/<name.md
- Agents/<name/AGENT.md
- Whether under .claude/agents/
- Inside a plugin
Example prompts
- “Use the reviewing-agent-definitions skill to review Claude Code agent definition files for tool-access security, triggering quality, and system…”
- “/reviewing-agent-definitions”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob
What it can do on your machine
Read from SKILL.md and the folder at commit 0e684b9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Reviewing Agent Definitions loads about 2.4k tokens when it runs. Until then it costs about 155 tokens; SKILL.md has 1,097 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,097 words (~2,442 tokens).
“Agents run with a tool grant a contributor chose. The grant is the review's centre of gravity: everything else is quality, but an over-broad grant is a security weakening that ships silently.”
