What it does
Reviewing Claude Config is an agent skill from bitwarden/ai-plugins, published by the product's own GitHub organization. Reviews Claude configuration files for security, structure, and prompt engineering quality. Use when reviewing changes to CLAUDE.md, agents, prompts, commands, hooks, or settings. Routes each file type to a targeted review skill and returns classified findings. Flags settings.local.json appearing in a changeset, hardcoded secrets, malformed YAML, insecure agent tool access, and unsafe hook commands. Does not review SKILL.md files — plugin-dev:skill-reviewer owns those.
Its SKILL.md is about 4.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts (for example `reference/claude-code-requirements.md`, `reference/priority-framework.md` and `reference/security-patterns.md`).
It sits in Agent Workflows, covering Secrets management, Skill authoring and Agent instruction files. The repository describes itself as: AI plugin marketplace.
When your agent uses it
- Reviewing changes to CLAUDE.md
- Tasks that involve Secrets management
- Tasks that involve Skill authoring
Example prompts
- “Use the reviewing-claude-config skill to review Claude configuration files for security, structure, and prompt engineering quality”
- “/reviewing-claude-config”
Requirements
- A Bash shell
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Skill
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Settle what is in scope
- Security scan (always)
- Route to the targeted review skill
- Filter before reporting
- Return findings
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:
ReadGrepGlobSkill
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Shell), which the agent can run.
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 Claude Config loads about 4.2k tokens when it runs. Until then it costs about 124 tokens; SKILL.md has 2,122 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); the scripts in this folder 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 2,122 words (~4,173 tokens).
“This skill is the entry point. It settles scope, runs the security scan, routes each file type to a targeted review skill, filters the results, and returns classified findings.”
