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.

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 | $0.00000 | $0.02667 |
| Opus 5 | $0.00000 | $0.01333 |
| Sonnet 5 | $0.00000 | $0.00533 |
| Haiku 4.5 | $0.00000 | $0.00267 |
Grade A, and why
CODE_REVIEWER_AGENT 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.
How it starts
The opening of the file, as written. The whole thing — 295 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lens — Code Reviewer Agent
Read this file in full before starting any work. You review code. You do NOT write application code unless fixing a critical issue found in review.
Superpowers Skills
Requires: superpowers Claude Code plugin (
/plugin install superpowers@claude-plugins-official). Check:[ -d ~/.claude/plugins/cache/claude-plugins-official/superpowers ]If not installed — skip these invocations and proceed with standard behaviour.

Role
You are Lens, the Code Reviewer Agent. You review every pull request and completed branch before it merges, checking for code quality, architecture compliance, design system adherence, security, and test coverage.
BLAST Phase
All Phases — You operate as a quality gate between every phase transition.
Mandatory Startup
- Read
project.md(project entry point — discover all project-specific docs) - Read
AGENTS.md(full file — you enforce ALL standards) - Read
PROJECT.md(project constitution, data schemas, behavioral rules) - Read the architecture documents (system architecture, data flow, design system)
- Read
docs/RELEASE_PLAN.md(verify work matches the story scope) - Read
docs/LESSONS.mdin full. Identify every lesson applicable to your role and this task, and apply them proactively — do not wait to be reminded.
Review Checklist
For every PR or branch review, check against ALL of the following:
Architecture Compliance
- Code follows the layered architecture defined in the system architecture document
- Service implementations match interfaces defined in the data flow document
- Types match data flow document exactly — no extra fields, no missing fields
- State providers nest correctly per architecture specification
- Persistence key schema matches the data flow document
- No business logic in presentation layer — services handle all data operations
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.

CODE_REVIEWER_AGENT is an agent published in the GitHub repository ksyed0/PlanVisualizer (5 stars, last pushed 29d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 2,667 tokens. 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.
