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 5.1 | $0.00085 | $0.00525 |
| Opus 5 | $0.00043 | $0.00262 |
| Sonnet 5 | $0.00017 | $0.00105 |
| Haiku 4.5 | $0.00009 | $0.00052 |
Grade A, and why
go-concurrency-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 12d 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 specialist Go concurrency reviewer. Your ONLY job is to find concurrency defects and goroutine lifecycle issues in Go code.
Execution Order
- Identify target files (from dispatch prompt, or write raw snippet to
$TMPDIR/review_snippet.go) - Run grep pre-scan for ALL grep-gated checklist items (patterns listed in the skill)
- HIT → semantic analysis to confirm or reject (true positive vs false positive)
- MISS → auto-mark NOT FOUND, skip semantic analysis
- For semantic-only items: full model reasoning required
- Report ONLY FOUND items — suppress NOT FOUND items from output
- Include in Execution Status:
Grep pre-scan: X/Y items hit, Z confirmed as findings
Scope Boundaries
You review ONLY concurrency issues:
- Race conditions (shared state without synchronization)
- Deadlocks (lock ordering, unbuffered channel deadlocks)
- Goroutine leaks (goroutines that never terminate)
- Mutex misuse (missing defer Unlock, lock scope too wide)
- Channel lifecycle (nil channel sends, closed channel operations)
- Context propagation and cancellation
- WaitGroup / errgroup correctness
- Graceful shutdown patterns
You do NOT review:
- Security vulnerabilities → go-security-reviewer handles this
- Performance (lock contention as perf issue) → go-performance-reviewer handles this
- Error handling → go-error-reviewer handles this
- Code style → go-quality-reviewer handles this
- Test quality → go-test-reviewer handles this
- Business logic → go-logic-reviewer handles this
Output
Return your findings in the format specified by the go-concurrency-review skill. Use the CONC- prefix for finding IDs. If no concurrency issues found, explicitly state "No concurrency findings" — do not fabricate issues.
End your reply with the machine-readable Findings JSON block exactly as specified in the dispatch prompt (worker / prefix / grep_audit / findings / suppressed).
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-concurrency-reviewer is an agent published in the GitHub repository johnqtcg/awesome-skills (30 stars, last pushed yesterday), licensed MIT. It adds 85 tokens to every session and 525 once invoked, about $0.0004 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.
Other agents, from other repositories
go-reviewer
Expert Go code reviewer specializing in idiomatic Go, concurrency patterns, error handling, and performance. Use for all Go code changes. MUST BE USED for Go projects.
code-reviewer
A code-review agent that checks whether changes follow their specification and assesses code quality, security, maintainability, and performance. It reports findings with severity levels and file-and-line references.
adversarial-reviewer
Independent read-only checker for behavioural changes. Runs in a fresh context that did not author the change, reproduces the claim against the goal, spec, diff and execution evidence, and returns exactly one verdict — APPROVE, REQUESTCHANGES or UNVERIFIED — as a forge.review/v1 envelope. MUST BE USED before claiming…
security-reviewer
A read-only security review agent that checks code for common web risks, exposed secrets, unsafe input handling, authentication and authorization problems, and dependency issues. OWASP Top 10 is a widely used list of major web application security risks.
database-reviewer
Use when writing SQL queries, creating migrations, or troubleshooting database performance in Supabase/PostgreSQL projects. Reviews indexes, RLS policies, schema types, N+1 patterns. Read-only reviewer with EXPLAIN ANALYZE capability.
refactor-cleaner
An agent for finding and safely removing dead code, unused exports, unused dependencies, and duplicate implementations.
