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 | $0.00121 | $0.01548 |
| Opus 5 | $0.00060 | $0.00774 |
| Sonnet 5 | $0.00024 | $0.00310 |
| Haiku 4.5 | $0.00012 | $0.00155 |
Grade A, and why
code-review 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/code-review — MCP-Powered Code Review
What
Performs a multi-dimensional code review combining Roslyn MCP analysis with structured manual review. Effort follows the 80/20 rule: the 20% of code that causes 80% of incidents (data access, security, concurrency, integration boundaries) gets thorough review; style and formatting are left to tooling.
Review dimensions: Correctness (logic, edge cases, null handling, async pitfalls), Security (auth gaps, injection, secrets, CORS), Performance (N+1, allocations, missing cancellation), Architecture compliance (layer violations, boundary breaches), Test coverage (behavior tests for changed types).
When
- "Review this", "code review", "PR review", before merging a pull request
- After a major refactor to verify no regressions or design drift
- "What should I review?" — deciding where review effort goes on a large change
- Onboarding to unfamiliar code and wanting a quality assessment
How
Step 1: Scope and Score Blast Radius
Identify changed files (git diff main...HEAD, specified files, or module).
Score each change to set review depth — blast radius determines depth, not
line count. A one-line middleware change outranks a 300-line rename.
| Blast Radius | Examples | Depth |
|---|---|---|
| Critical | Middleware, auth, DB migrations, shared kernel, CI/CD | Thorough — every code path |
| High | Public API changes, message consumers, EF configuration, new module | Focused — consumers + behavior |
| Medium | New feature following existing patterns, bug fix, new endpoint | Standard — checklist pass |
| Low | Docs, formatting, renames, logging statements | Glance — build + tests pass |
Step 2: MCP Analysis (before reading any file)
detect_antipatterns(projectFilter: "affected-project") → async void, DateTime.Now, new HttpClient(), broad catch
get_diagnostics(scope: "project", path: "affected-project") → new warnings, nullability issues
Distinguish newly introduced findings from pre-existing ones — focus on new.
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-review is a skill published in the GitHub repository codewithmukesh/dotnet-claude-kit (689 stars, last pushed 26d ago), licensed MIT. It adds 121 tokens to every session and 1,548 once invoked, about $0.0006 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.
