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 | $0.00014 | $0.00169 |
| Opus 5 | $0.00007 | $0.00084 |
| Sonnet 5 | $0.00003 | $0.00034 |
| Haiku 4.5 | $0.00001 | $0.00017 |
Grade A, and why
perf-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 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.
This is a copy
100% identical to perf-review — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Review $ARGUMENTS (default: uncommitted changes; if clean, the last commit) for performance issues.
Focus on the high-payoff categories for an ASP.NET Core + EF Core app: N+1 query patterns, missing AsNoTracking on reads, full-entity loads where projections suffice, queries inside loops, sync-over-async, sequential awaits that are safely parallelizable, allocations in hot paths, and missing pagination on growing collections.
Output: findings ranked by expected impact, each with location, mechanism (why it is slow), and a concrete fix. If nothing significant, say so in one line — do not manufacture findings. For deep analysis of the whole codebase, suggest delegating to the perf-analyzer subagent instead.
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.

perf-review is a command published in the GitHub repository cwoodruff/dotnet-claude-code-kit (2 stars, last pushed 1mo ago), licensed MIT. It adds 14 tokens to every session and 169 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to perf-review, differing in 0 lines, and is treated as a copy.
