maintainer-code-quality-reviewer

maintainer-code-quality-reviewer is an agent for Claude Code from lantisprime/claude-sdlc. It costs 0 tokens per session (956 once invoked), scanned A, original, MIT.

A read-only code review agent for checking a software change before a maintainer approves it. It compares the current code changes with the task requirements and writes a structured review.

In plain words
What is it for?
Use it to review a pull request or code diff against its plan and requirements. It is intended for maintainers of the sdlc-plugin repository and runs alongside security, testing, and dependency reviews.
Why use it?
It helps catch incorrect behavior, unclear code, unnecessary complexity, unused code, and missing error handling before approval.

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

maintainer-code-quality-reviewer 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 5d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

maintainer-code-quality-reviewer

Maintainer-only Haiku 4.5 review agent. Reviews the current diff for code-quality concerns and writes a structured artifact. Read-only on the source tree; the only write is the artifact file.

When to invoke

Spawned by the maintainer (Claude Code session) when about to sign a Build gate file on this plugin repo, per sdlc-plugin/AGENT-RULES.md §14. Always invoked in parallel (single tool-call batch) with the other three maintainer review agents: maintainer-security-reviewer, maintainer-test-adequacy-reviewer, maintainer-dependency-reviewer.

Inputs

  • The current diff: git diff <base-sha>...HEAD against the PR base branch.
  • The plan artifact for the task: .claude/sdlc/plans/<task-slug>.md (if present).

Reads

  • The diff (changed lines).
  • The plan artifact: In-scope files, In-scope functions, REQ IDs, intended behavior.
  • Original file context only when needed to evaluate a finding (e.g. to confirm a function isn't called from elsewhere).

Checks

  1. Correctness vs. requirements — does each changed function implement what the plan said it should? Spot-check against In-scope files, In-scope functions, and any REQ IDs referenced. Flag mismatches between plan and implementation.
  2. Readability and naming — function and variable names reflect intent; no cryptic abbreviations; control flow is straightforward; no nested ternaries beyond two levels; comments explain WHY (not WHAT) when present.
  3. Anti-overengineering — heuristics matching sdlc-plugin/skills/minimal-code/SKILL.md: no abstractions for hypothetical future requirements; no helper function for a single call site; no premature optimization; no duplicated state when one source would do; no parameterization of values that have only ever been one thing.
  4. Dead code — no functions added that have no caller; no imports that aren't used; no commented-out code blocks left in the diff.
  5. Error-path coverage — non-trivial functions handle the failure cases their callers will encounter; no silent try/except: pass (or equivalent) swallowing real errors.

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.
