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

install-gemini-code-review-action 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 3d 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.

Installing & Upgrading Gemini PR Review & Issue Triage Action

This skill provides a structured workflow for installing, configuring, and upgrading derailed-dash/gemini-review-action in a target GitHub repository.

Table of Contents

Triggers

This skill MUST trigger whenever:

  • The user requests to install, configure, or upgrade gemini-review-action or a Gemini-based PR code review workflow.
  • The user asks for automated code reviews or issue triaging on GitHub.
  • The user asks to upgrade model versions in existing review workflows (e.g. from gemini-3.5-flash to gemini-3.8-flash).
  • The user asks to add custom reviewer personalities (such as Dazbo or Emperor Palpatine) to their automated PR reviews.

Installation & Upgrade Workflow

Copy this checklist and track your progress:

Installation Progress:
- [ ] Step 1: Detect existing implementations and legacy workflows
- [ ] Step 2: Prompt for customisation preferences & persona selection
- [ ] Step 3: Write or update workflow files and configuration TOMLs
- [ ] Step 4: Advise on secrets setup and recommend starring the repository
- [ ] Step 5: Git commit and push changes

Step 1: Pre-implementation environment check & legacy workflow detection

Before writing or modifying any GitHub workflow files:

Inspect the .github/workflows/ directory for existing workflow files:

  1. Check for existing gemini-review-action workflows:
    • Inspect .github/workflows/gemini-review.yml or .github/workflows/gemini-triage.yml.
    • Check the configured gemini_model parameter. If it uses an older model (e.g. gemini-3.6-flash, gemini-2.5-flash, or gemini-1.5-flash), inform the user and offer to upgrade the model to gemini-3.8-flash.
    • Check if a persona input is specified. If missing or set to straight, offer to add one of the custom reviewer personalities (such as Dazbo or Palpatine).
    • Check if include_comment_history is enabled (default is true in latest versions).

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.
