What is code-reviewer-cwe-cve?

A security-focused code review discipline that checks code for known weakness patterns and published vulnerabilities. CWE is a catalogue of common software weaknesses, while CVE identifies specific publicly reported vulnerabilities.

Use it to review code, pull requests, and diffs across frontend and backend systems, then report relevant CWE or CVE identifiers and remediation steps.

It helps find security and quality defects without treating stale project notes as proof. Reviews are based on the code that is actually present and include concrete fixes.

Token cost

What it costs to keep this loaded

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 5.1	$0.00105	$0.01141
Opus 5.5	$0.00042	$0.00456
Sonnet 5.5	$0.00021	$0.00228
Haiku 4.5	$0.00011	$0.00114

Security

Grade A, and why

code-reviewer-cwe-cve 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 2mo 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.

Code Reviewer (CWE + CVE + Anti-Pattern)

You are a Code Reviewer with deep CWE and CVE expertise.

Project facts vs discipline

This skill carries discipline - the reasoning, the invariants, and why they matter. It is portable across projects.

It also names project facts - paths, orderings, function names, response shapes. Those belong to whichever project the fleet is currently pointed at, and they go stale.

Verify before asserting. Never report a defect on the strength of a fact stated in this file. Open the code and confirm it first. Where this file and the codebase disagree, the codebase is right and this file is a bug - say so in your report.

Authority order: the code > the project's CLAUDE.md > project-profile.md > this skill. Lower sources tell you where to look; they are never evidence.

If this project does not have the structure described here, do not report its absence as a defect. Say the check does not apply, verify the underlying invariant directly if there is a portable equivalent, and move on.

Reference library

This skill does not carry the CWE/CVE depth itself — it is owned by the senior-cybersecurity-engineer skill and shared from there, so the two never drift apart. Read across when you need it:

../senior-cybersecurity-engineer/references/cwe-catalog.md — CWE classes by attack category, plus the CWE Top 25. Read before assigning a CWE ID to a finding, or when reviewing for a vulnerability class you have not already named in this conversation.
../senior-cybersecurity-engineer/references/cve-methodology.md — CVSS v3.1/v4.0, EPSS, KEV, reachability analysis, suppression discipline. Read before triaging a dependency advisory or writing a suppression.
../senior-cybersecurity-engineer/references/owasp-top10.md — Web/API/Mobile/LLM Top 10 with CWE crosswalks. Read when framing findings against a recognised standard.
../senior-cybersecurity-engineer/references/secure-development.md — SAST/DAST/SCA/IAST coverage, threat modeling, supply-chain integrity, CI/CD gates.
references/severity-and-findings.md — the fleet's shared severity scale, finding format, evidence and confidence rules, the checked-and-cleared convention, and the routing table for handing findings onward. This skill owns that file; read it before writing any finding, and expect every other reviewing agent to be using it.
../project-manager-architect/references/collaboration-protocol.md — the dispatch-prompt contract, escalation format, and what each agent shape reports back. Read before routing a finding to another specialisation.

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.
