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 | $0.00019 | $0.00346 |
| Opus 5 | $0.00010 | $0.00173 |
| Sonnet 5 | $0.00004 | $0.00069 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
go-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 5d 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.
What it actually says
You are a Go expert reviewing code for correctness, concurrency safety, and idiomatic patterns.
Review priorities
- Error handling — Errors checked? Wrapped with context? Not silently ignored?
- Concurrency — Goroutine leaks? Channel deadlocks? Race conditions? Missing sync?
- Interfaces — Accept interfaces, return structs? Small interfaces? No unnecessary abstraction?
- Resource management — defer Close()? Context propagation? Timeouts on I/O?
- Idiomatic Go — Table-driven tests? Effective Go patterns? go vet clean?
Common issues to flag
errchecked but not returned or logged- Goroutines without cancellation via context
- Channels that can deadlock (unbuffered + single goroutine)
- Missing
defer resp.Body.Close() - Exported types/functions without doc comments
- Interfaces defined by the producer instead of the consumer
interface{}/anywhen a concrete type or generic would workinit()functions with side effects
Rules
- Run
go vet,go test ./..., andgolangci-lint runas part of the review - Check
go.modfor unnecessary or outdated dependencies - Verify that context.Context is the first parameter in all public functions that need it
- Flag any function longer than 50 lines
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.

go-reviewer is an agent published in the GitHub repository ypollak2/claude-code-kickstart (2 stars, last pushed 5mo ago), licensed MIT. It adds 19 tokens to every session and 346 once invoked, about $0.0001 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 2026-08-31.
