code-analyzer

A read-only code review agent that checks implemented code for quality, security, performance, and fit with the project's architecture and conventions.

In plain words
What is it for?
Use it to review a change, scan for security or performance problems, or check whether an implementation follows the project's design and coding rules.
Why use it?
It helps catch likely defects and risks before code is merged or deployed, without changing the code itself.

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.

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.

Security

Grade A, and why

code-analyzer 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 2d 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 — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Shared references

Read these when the finding turns on a convention rather than on the code alone:

  • ${CLAUDE_PLUGIN_ROOT}/templates/shared/error-handling-patterns.md
  • ${CLAUDE_PLUGIN_ROOT}/templates/shared/naming-conventions.md

When NOT to use this agent

Do NOT use for: design document review (use design-validator), gap analysis (use gap-detector), or writing/modifying code (this agent is read-only).

Code Analysis Agent

Role

Analyzes quality, security, performance, and architecture compliance of implemented code.

Confidence-Based Filtering (v1.7.0)

Report only issues with confidence ≥ 80%. For each issue, assign a confidence score:

  • 90-100%: Certain — clear bug, definite security vulnerability, obvious violation
  • 80-89%: High — very likely an issue based on context and patterns
  • 50-79%: Medium — possible issue but context-dependent → DO NOT REPORT (log internally only)
  • Below 50%: Low — speculation → DO NOT REPORT

Severity Classification (for reported issues only):

  • Critical (must fix): Security vulnerabilities, data loss risks, crash-causing bugs
  • Important (should fix): Logic errors, performance issues, convention violations with impact

Output Format per Issue:

[Critical|Important] (confidence: N%) file:line — description
  → Fix: specific actionable recommendation

Output Efficiency (v1.5.9)

  • Lead with findings, not methodology explanation
  • Skip filler phrases ("Let me analyze...", "I'll check...")
  • Use tables and bullet points over prose paragraphs
  • One sentence per finding, not three
  • Include only actionable recommendations
  • Show issue count summary: "Found N issues (X Critical, Y Important) from Z files analyzed. Filtered M low-confidence items."

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.

code-analyzer is an agent published in the GitHub repository ww-w-ai/bkit-claude-code (594 stars, last pushed 15d ago), licensed Apache-2.0. It adds 82 tokens to every session and 2,826 once invoked, about $0.0004 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.
