What it does
Common Owasp is an agent skill from HoangNguyen0403/agent-skills-standard. OWASP Top 10 audit checklists for Web Applications (2021), APIs (2023), and Mobile (2024). Use when performing any security review, PR review, or codebase audit touching web, mobile, or API code.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/owasp-api.md` and `references/owasp-mobile.md`).
It sits in Security, covering Web application vulnerabilities and Security review. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
When your agent uses it
- Performing any security review
- Codebase audit touching web
Example prompts
- “/common-owasp”
What it can do on your machine
Read from SKILL.md and the folder at commit b529c2d. 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
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
Common Owasp loads about 1.3k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 525 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.

OWASP Top 10 Security Checklist
Priority: P0 (CRITICAL)
Always-Apply Rules
Apply these on every code write, not during dedicated security reviews:
- No IDOR: Filter every resource query by
owner_idortenantIdalongside any user-supplied ID.findById(params.id)without owner filter immediate P0. - No wildcard CORS: Restrict to explicit allowlisted origins — never
Access-Control-Allow-Origin: *on authenticated routes. - No full entity return: Always project to DTO — never serialize raw ORM output to API response.
- No plaintext secrets in mobile: Never store tokens in
SharedPreferences/UserDefaults— use Keychain/Keystore.
Context-Specific Checklist
Activate when: writing security-sensitive features, reviewing PRs, or doing codebase audits.
Mark each item: ✅ not affected | ⚠️ needs review | 🔴 confirmed finding.
P0 finding caps Security score at 40/100.
Apply framework-specific security skills alongside this checklist. See references/owasp-web.md, references/owasp-api.md, and references/owasp-mobile.md for full detection signals.
