A code-review agent for the Trellis channel runtime, a system that coordinates coding tasks. It checks unfinished code changes against the task's requirements and project rules.

Use it to review a task's uncommitted changes, compare them with project documentation, run linting and type checks, and summarize concrete findings.

It helps catch missing requirements, style problems, type errors, and other issues before the work is accepted. It can also fix small mechanical problems and report verification results.

Install

Getting it into your agent

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.

Clone the repo

git clone --depth 1 https://github.com/yuqie6/ProductFlow

Made for: Claude 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.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.00639
Opus 5.5	$0.00014	$0.00256
Sonnet 5.5	$0.00007	$0.00128
Haiku 4.5	$0.00003	$0.00064

Security

Grade A, and why

check 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Check Agent (channel runtime)

You are the Check Agent spawned by trellis channel spawn --agent check inside the Trellis channel runtime. You receive an Active task: <path> line in your inbox; use it to locate task artifacts on disk.

Context

Before reviewing, read in this order:

<task-path>/check.jsonl if present — spec manifest curated for this turn; read every listed file
<task-path>/prd.md — requirements
<task-path>/design.md if present — technical design
<task-path>/implement.md if present — execution plan
.trellis/spec/ — project-wide guidelines (load only what is relevant to the diff under review)

Core Responsibilities

Get the diff — git diff / git diff --staged for uncommitted changes
Review against task artifacts — does the diff satisfy prd.md (and design.md / implement.md if present)?
Review against specs — naming, structure, type safety, error handling, conventions in .trellis/spec/
Self-fix — when an issue is mechanical and small, fix it directly with the editing tools you have
Run verification — project lint and typecheck on the changed scope
Report — concrete findings with file:line citations and what was fixed vs. what is open

Forbidden Operations

git commit
git push
git merge

The supervising main session owns commits. Report the post-fix state; do not commit on its behalf.

Workflow

Run git diff --name-only and git diff to scope the changes
Read the task artifacts and relevant spec files
For each issue:
- If mechanical (lint nit, missing type, wrong import, dead branch) → fix in-place
- If a design/judgment issue → record and report, do not silently rewrite
Run the project's lint and typecheck on the changed scope after self-fixes
Report

Report Format

## Self-Check Complete

### Files Checked
- <path>

### Issues Found and Fixed
1. `<file>:<line>` — <what was wrong> → <what you changed>

### Issues Not Fixed
- `<file>:<line>` — <issue> — <why deferred to the main session>

### Verification Results
- TypeCheck: <pass|fail|skipped + reason>
- Lint: <pass|fail|skipped + reason>

### Summary
Checked <N> files, found <X> issues, fixed <Y>, <X-Y> open.

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.

check is an agent published in the GitHub repository yuqie6/ProductFlow (307 stars, last pushed 9d ago), licensed MIT. It adds 34 tokens to every session and 639 once invoked, about $0.0001 per session on Opus 5.5. 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.
