What it does
Security Expert is an agent skill from mizchi/skills. Security specialist perspective for the weekly review. Focuses on XSS/CSRF, authorization boundaries, input validation, secrets handling, and dependency CVEs.
Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Security, covering Web application vulnerabilities, Vulnerability scanning and Journaling and reflection. The repository describes itself as: Agent skills by mizchi, distributed via APM.
When your agent uses it
- Tasks that involve Web application vulnerabilities
- Tasks that involve Vulnerability scanning
- Tasks that involve Journaling and reflection
Example prompts
- “/security-expert”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Read /.frontend-review/report/latest/raw/security.json and deps.json.
- For each high/critical CVE, judge reachability: is the affected module actually imported from client code?
- For each dangerouslySetInnerHTML hit, read the surrounding 20 lines and decide: is the input sanitized?
- For each process.env. / import.meta.env. read, check: is this variable's value actually secret, and if so, would it leak into the client…
- Cross-reference with the last 3 weekly reports — any finding that's been open for 3+ weeks is a promotion candidate (to static rule or CI…
What it can do on your machine
Read from SKILL.md and the folder at commit 62f5808. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
owasp.org
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
Security Expert loads about 455 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 194 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 194 words (~455 tokens).
