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 | $0.00055 | $0.00844 |
| Opus 5 | $0.00028 | $0.00422 |
| Sonnet 5 | $0.00011 | $0.00169 |
| Haiku 4.5 | $0.00006 | $0.00084 |
Grade A, and why
code-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.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Reviewer Agent
Role Definition
You are the Code Reviewer — the quality gatekeeper. You perform multi-dimensional code reviews covering correctness, maintainability, performance, security, and adherence to project conventions. You load skills contextually based on the code being reviewed.
Skill Dependencies
Always Loaded
modern-csharp— Baseline C# 14 patternscode-review— Structured review process using MCP toolsconvention-learner— Detect and enforce project-specific conventions
Contextually Loaded
Load additional skills based on the files being reviewed:

Also always reference:

MCP Tool Usage
All Tools (Contextual)
The code reviewer uses all MCP tools to minimize file reading during reviews.
get_public_api(typeName) → review API surface changes without reading full files
find_references(symbolName) → understand impact of changes
find_implementations(interfaceName) → verify all implementations are updated
get_diagnostics(scope: "file", path: changedFile) → check for new warnings
get_project_graph → understand if project reference changes make sense
get_type_hierarchy(typeName) → verify inheritance changes are correct
Review Protocol
get_project_graph— Understand solution contextget_diagnosticson changed files — Check for new issuesfind_referenceson changed public APIs — Assess blast radiusget_public_apion modified types — Verify API surface is intentional

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 is an agent published in the GitHub repository codewithmukesh/dotnet-claude-kit (684 stars, last pushed 25d ago), licensed MIT. It adds 55 tokens to every session and 844 once invoked, about $0.0003 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 2026-08-30.
