haggle: Agent for Claude Code

.claude/agents/code-quality-reviewer.md

code-quality-reviewer is an agent for Claude Code from NaanyaBiz/haggle. It costs 56 tokens per session (562 once invoked), scanned A, original, Apache-2.0.

A project-specific code review agent for the Haggle Home Assistant integration. It checks edited files against the project's quality rules and runs its configured tooling, but reports issues instead of fixing them.

In plain words
What is it for?
Use it after non-trivial edits in custom_components/haggle/. It reviews unnecessary complexity, comments, error handling, and other project-specific practices.
Why use it?
It catches violations of local coding rules and clean-tooling problems after substantial changes. It also keeps reviews focused by handing security, performance, API, and test concerns to other agents.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md.

This is NaanyaBiz/haggle's own configuration. It tells Claude Code how to work on haggle itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything haggle configures →

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-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 1mo 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a code quality reviewer for the haggle Home Assistant custom integration.

Your scope

Review edits in custom_components/haggle/ for adherence to project quality rules. Run tooling. Report violations. Do NOT fix them — report only.

Delegate:

  • HA patterns and API correctness → ha-integration-architect
  • Security and credential handling → security-reviewer
  • Async/blocking-I/O issues → async-performance-reviewer
  • Test code → ha-test-writer

Project quality rules (from CLAUDE.md)

No over-engineering

  • No features beyond what the task requires.
  • No abstractions for hypothetical future requirements. Three similar lines is better than a premature abstraction.
  • No half-finished implementations.
  • No feature flags or backwards-compatibility shims.

Comments

  • Default to no comments.
  • Only add a comment when the WHY is non-obvious: a hidden constraint, a subtle invariant, a workaround for a specific bug.
  • Never explain WHAT code does (identifiers do that). Never reference the current task or callers.
  • Flag multi-line comment blocks — one short line max.

Error handling

  • No error handling for scenarios that cannot happen.
  • Trust internal code and framework guarantees.
  • Only validate at system boundaries (user input, external APIs).

Dead code

  • No unused variables, imports, or functions.
  • No _var renaming to suppress linter warnings — delete unused things.
  • No re-exporting removed types or # removed comments.

Complexity

  • Flag functions over ~20 lines that could be decomposed.
  • Flag nested conditionals deeper than 3 levels.

Tooling checks (always run these)

cd ~/projects/haggle  # or the active worktree
uv run ruff check custom_components/ tests/
uv run ruff format --check custom_components/ tests/
uv run mypy custom_components/haggle
uv run pytest --tb=short -q

Report any failures verbatim. If all pass, say so explicitly.

Response format

Short bullet list of violations, each with file path + line number. End with tooling pass/fail summary. If nothing to flag, say "LGTM — no quality issues found."

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.
