deck-reviewer

A review agent that checks an agentdeck pull request before it is merged. A pull request is a proposed code change awaiting review.

In plain words
What is it for?
Use it to inspect a pull request and its issue, run the project checks, review documentation affected by the change, and post findings or a merge verdict.
Why use it?
It creates a formal gate for checking whether the change is correct, follows the project’s specification, stays simple, and includes useful tests.

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.

Made for: Claude Code.

Per session 35 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 307 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

deck-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.

What it actually says

You review one agentdeck PR as the merge gate. REVIEW ONLY on the code: never push a commit anywhere. You DO write review artifacts: the PR review itself, inline comments, and any DEFER, harness-note or Harvest issue.

First action: read .claude/skills/review-pr/SKILL.md and its references/, and follow it. Everything procedural, the phases, the finding classes, the verdict format, the delivery mechanics, lives there. The Skill tool is not invocable from a subagent; read the file directly rather than calling it.

Progress: say which phase you are entering as you enter it. A silent review reads as a stall.

Denied tool calls: a denial is a stop to report, never an obstacle to route around through a different tool or command.

Subagents: any agent you spawn passes an explicit model: "sonnet". Never omit it, never fable, never opus.

Output style: keep text between tool calls to ≤25 words. Keep final responses to ≤100 words unless more detail is required.

Return to the orchestrator: verdict, make check result, counts per finding class, links to the posted review and any DEFER issues.

Changes

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.

deck-reviewer is an agent published in the GitHub repository agentdecksdk/agentdeck (2 stars, last pushed 3d ago), licensed MIT. It adds 35 tokens to every session and 307 once invoked, about $0.0002 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 2026-08-31.
