Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00027 | $0.01391 |
| Opus 5 | $0.00014 | $0.00696 |
| Sonnet 5 | $0.00005 | $0.00278 |
| Haiku 4.5 | $0.00003 | $0.00139 |
Grade A, and why
secure-code-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What this skill does
Performs a structured security-focused code review across 10 domains: Input Validation, Authentication & Session Management, Authorization & Access Control, Injection Prevention, Cryptography, Error Handling & Logging, Data Protection, Dependency Security, Configuration Security, and Race Conditions. Maps findings to CWE identifiers and severity levels, and produces a report with remediation guidance and proof-of-concept notes.
When to use
- During pull request review for security-sensitive code changes (auth, payments, file handling, crypto)
- Before a production release to verify security controls are in place
- When onboarding a legacy codebase with no prior security review history
- When a bug bounty report or vulnerability disclosure references a code-level flaw requiring root cause analysis
Prerequisites
- No external tools required (checklist-based; use with source code access)
- Read access to the source code under review
- (Optional) Static analysis output from tools such as Semgrep, CodeQL, or Bandit to supplement manual review
- CWE reference: https://cwe.mitre.org
Inputs
| Item | Description | Example |
|---|---|---|
REPO_PATH |

Primary language(s) of the codebase | Python, TypeScript, Go |
REVIEW_SCOPE |
Files, modules, or PR diff to review | auth/, payments/handler.py, PR #342 |

Workflow
Step 1: Define Review Scope
Before starting the checklist, bound the review to avoid scope creep and ensure thoroughness within the defined boundary.
## Review Scope
- **Repository / Path**: <REPO_PATH>
- **Language(s)**: <LANGUAGE>
- **Files reviewed**: <list each file or PR diff>
- **Review date**: <YYYY-MM-DD>
- **Reviewer**: <name or agent>
- **Total lines reviewed**: <approximate>
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

secure-code-review is a skill published in the GitHub repository woohyun212/security-skill (21 stars, last pushed 4mo ago), licensed MIT. It adds 27 tokens to every session and 1,391 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
