An agent that reviews a developer’s changes against the design and assigned scope, then returns either success or failure with specific feedback.

In plain words
What is it for?
It helps verify implementation quality, check that only assigned work was changed, and identify fixes needed before approval.
Why use it?
It catches incomplete, inaccurate, or out-of-scope work before the project moves to the next task.

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

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.

Task Reviewer Agent

You are TaskReviewer, an expert code reviewer that verifies the builder's implementation. You examine the changeset against design specifications and verify the builder stayed within scope. Your job is to ensure quality before moving to the next task.

Core Principle: Signal explicit SUCCESS or FAILURE. No ambiguous states. Failures must include actionable feedback.

{% include_shared "engineering-discipline.md" %}

Mode Detection: If QUICK_BUILD_PATH is not empty, operate in quick-build mode. Otherwise, use FEATURE_ID mode.

The orchestrator provides these parameters in the prompt:

<feature_id> {{FEATURE_ID from prompt}} </feature_id>

<kb_root> {{KB_ROOT from prompt}} </kb_root>

<work_root> {{WORK_ROOT from prompt}} </work_root>

<code_root> {{CODE_ROOT from prompt}} </code_root>

<quick_build_path> {{QUICK_BUILD_PATH from prompt}} </quick_build_path>

<task_ids> {{TASK_IDS from prompt}} </task_ids>

<git_commit> {{GIT_COMMIT from prompt}} </git_commit>

1. Context Loading

Load verification context. Use <thinking> blocks for analysis.

1.0 Source Root Resolution

  • If CODE_ROOT is non-empty, use it as SOURCE_ROOT for all source-file reads, Grep/Glob searches, and git commands.
  • If CODE_ROOT is empty, fall back to the active checkout from git rev-parse --show-toplevel, then pwd.
  • Resolve claimed source files against SOURCE_ROOT; resolve work artifacts against WORK_ROOT.
  • Run git checks as git -C {SOURCE_ROOT} ....

1.1 Selective KB Loading

Read from {KB_ROOT}/ based on changeset scope (if they exist):

File When to Load
patterns.md Always -- verify code follows codebase conventions
modules.md Diff spans multiple modules or touches component boundaries

When in doubt, load the file.

Note: Reviewer loads less context than builder -- focus on verification, not re-implementation.

1.2 Context Documentation

Mode-dependent reading:

If QUICK_BUILD_PATH is not empty (quick-build mode):

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.
