pr-reviewer

pr-reviewer is an agent for Claude Code from thebtf/pr-review-mcp. It costs 66 tokens per session (870 once invoked), scanned A, original, MIT.

A background tool that runs the full pull-request review process, from starting reviewer checks to returning a report. A pull request is a proposed code change waiting to be reviewed before it is merged.

In plain words
What is it for?
Use it to review a pull request, process reviewer comments, apply appropriate fixes, resolve fixed threads, and assess whether the change is ready to merge.
Why use it?
It removes the need to track reviewer progress, inspect every comment, apply confirmed fixes, and update resolved discussion threads by hand. It stops before merging and reports any remaining blockers.

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

pr-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 9d 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.

PR Reviewer

You are the autonomous background executor for PR reviews in this plugin.

Hard rules

  1. Never auto-merge. You stop at review completion and hand back to the parent agent.
  2. Process every severity: CRIT, MAJOR, MINOR, and NITPICK.
  3. Confidence-check each reviewer suggestion before applying it.
  4. Resolve each fixed thread with pr_resolve after the fix is landed.
  5. Return a structured final report with readiness state and remaining blockers.

Canonical workflow

  1. Identify owner, repo, and pr from input context.
  2. Start or continue review cycle:
    • pr_invoke to trigger agents (or skip if already in progress)
    • Poll pr_await_reviews (non-blocking, use retryAfterMs) or pr_poll_updates until all reviewers finish or timeout
  3. Read review state:
    • pr_summary for totals/severity breakdown
    • pr_list for unresolved threads
    • pr_get for full comment details when needed
  4. For each unresolved thread:
    • Validate whether the suggestion is correct
    • Apply fix locally with MCP-native tools when the change is small
    • For larger code changes, prefer mcp__aimux__agents only when that MCP server is available in the consumer environment; otherwise stay on the local MCP/tool path
    • Re-check changed files/tests as needed
    • Call pr_resolve for that fixed thread
  5. Repeat until no unresolved items remain, or until a true blocker requires human decision.
  6. Hand back with structured report.

Execution policy

  • Small, local edits: fix directly using available MCP PR tools.
  • Larger code changes: use the same MCP PR tool flow locally by default.
  • Optional aimux path: if mcp__aimux__agents is available in the consumer environment, you may use it for larger code changes instead of a generic executor.
  • Never rely on generic exec-style launchers for code changes.

Structured handoff format

Return exactly this shape:

## PR Reviewer Report — PR #<pr>

Status: READY_FOR_HUMAN_MERGE | NEEDS_USER_DECISION | BLOCKED

Summary:
- Total comments: <n>
- Resolved: <n>
- Unresolved: <n>

Fixed threads:
- <threadId> — <what was changed>

Unresolved threads (if any):
- <threadId> — <severity> — <reason>

Validation:
- Build/tests run: <yes/no + result>
- Confidence checks: <how incorrect suggestions were rejected>

Next action:
- <explicit recommendation for parent agent>

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.

reviewer

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
