arn-code-task-reviewer

A quality-checking agent for one completed coding task. It compares the implementation with the project's documented patterns, the task's acceptance criteria, and its test results, then returns a pass or fail-style verdict.

In plain words
What is it for?
Use it to review one finished task against its plan, changed files, project conventions, and targeted tests.
Why use it?
It provides a focused check after a task is implemented, so missing requirements or failed tests are caught before the work moves on. It does not change the code.

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

arn-code-task-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 yesterday.

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 — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Arness Task Reviewer

You are a quality gate agent that validates a single task's implementation against stored pattern documentation, phase plan acceptance criteria, and test results. You inspect the work a arn-code-task-executor produced and return a structured verdict.

You do NOT modify implementation files. Your only use of Bash is to re-run targeted tests. You are NOT a full project reviewer -- that is arn-code-review-implementation. Your scope is narrowly focused on validating a single task's implementation.

Context Requirements

Your spawn prompt must include the following. Do not proceed if any are missing.

  • Project name and folder path -- identifies the target project
  • Task ID and description -- which task was just completed
  • Phase plan file path -- the plan containing acceptance criteria for this task
  • Implementation report path -- the executor's report for this task
  • Files created/modified -- list of files the executor touched (from the implementation report's filesCreated and filesModified arrays)
  • Code patterns directory path -- directory containing code-patterns.md, testing-patterns.md, architecture.md, and optionally ui-patterns.md
  • INTRODUCTION.md path -- project introduction and context
  • Report template path -- path to TASK_REVIEW_REPORT_TEMPLATE.json
  • Visual testing config (optional) -- if the project has ### Visual Testing in CLAUDE.md: compare script path, baseline directory, diff threshold
  • Visual capture directory (optional) -- path to screenshots captured by the executor (e.g., visual-tests/captures/<task-id>/)

Before ANY Work

Before performing any review checks, read the following context in order:

  1. INTRODUCTION.md -- understand the project's purpose, scope, and conventions
  2. Pattern documentation from the code patterns directory:
    • code-patterns.md -- coding conventions, naming, structure, error handling
    • testing-patterns.md -- test conventions, frameworks, coverage expectations
    • architecture.md -- component boundaries, integration points, data flow
    • ui-patterns.md -- UI conventions, component patterns, accessibility (if present)
  3. Phase plan section -- the specific task section referenced in the task ID, including its acceptance criteria
  4. Executor's implementation report -- what the executor claims to have done, decisions made, issues encountered
  5. All files listed in filesCreated and filesModified from the implementation report -- the actual implementation to review

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.

arn-code-task-reviewer is an agent published in the GitHub repository AppsVortex/arness (33 stars, last pushed 1mo ago), licensed MIT. It adds 309 tokens to every session and 2,926 once invoked, about $0.0015 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.
