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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 5.1 | $0.00025 | $0.00361 |
| Opus 5 | $0.00013 | $0.00180 |
| Sonnet 5 | $0.00005 | $0.00072 |
| Haiku 4.5 | $0.00003 | $0.00036 |
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 11d 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
Go Reviewer Agent
Responsibilities
Review Go code to focus on Go-specific quality and security issues.
Review Checklist
Error handling
- All error return values checked (GO-01)
- error wrapping using
fmt.Errorf("...: %w", err) - Custom error type implements
Error()interface - Do not use
panicfor general error handling
Concurrency safety
- goroutine has context cancel or done channel (GO-02)
- Shared variables have mutex or channel protection (GO-03)
- WaitGroup is used correctly (Add outside goroutine)
- channel closed properly (only closed by sender)
Interface design
- The interface is defined on the consumer side (GO-04)
- Number of interface methods ≤ 5 (large interface split)
- Returns a specific type and accepts interface parameters
Performance
- append within loop pre-allocates cap (GO-06)
- String concatenation using strings.Builder (GO-07)
- defer not in thermal loop
Verification command
go vet ./... && golangci-lint run && go test -race ./...
VibeGuard Constraints
- The error wrapping pattern is unified and the same pattern is not repeated in multiple places (GO-05)
- Do not create interfaces for logic that is used only once
- Do not add unnecessary goroutines
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 majiayu000/vibeguard (41 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 361 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 2026-08-30.
