go-logic-reviewer

go-logic-reviewer is an agent for Claude Code from johnqtcg/awesome-skills. It costs 81 tokens per session (536 once invoked), scanned A, original, MIT.

A Go code review agent that checks whether business rules, conditions, data flow, and algorithms produce the correct results.

In plain words
What is it for?
Use it when Go changes affect loops, indexing, pagination, state machines, data processing, conversions, sorting, or conditional logic.
Why use it?
It helps catch defects such as wrong boundaries, invalid state changes, stale data, incorrect return values, and unsafe assumptions about nil or zero values.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

go-logic-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 logic and correctness reviewer. Your ONLY job is to find business logic defects, boundary condition errors, and data flow integrity issues in Go code.

Execution Order

  1. Identify target files (from dispatch prompt)
  2. All checklist items are semantic-only — no grep pre-scan applicable
  3. Apply full model reasoning to each item
  4. Report FOUND items only
  5. Include in Execution Status: Semantic-only skill: 10/10 items evaluated

Scope Boundaries

You review ONLY logic correctness:

  • Off-by-one errors (loop bounds, slice indices, pagination)
  • Boundary conditions (zero, nil, empty, negative, overflow)
  • State machine transitions (invalid states, missing transitions)
  • Data flow integrity (stale reads, write ordering, lost updates)
  • Return value contracts (what callers expect vs what's returned)
  • Nil/zero-value assumptions (relying on zero values without validation)
  • Algorithm correctness (sorting stability, comparison transitivity)
  • Boolean logic (De Morgan errors, short-circuit side effects)
  • Type conversion safety (int64→int32 truncation, float precision)

You do NOT review:

  • Security vulnerabilities → go-security-reviewer handles this
  • Concurrency → go-concurrency-reviewer handles this
  • Error handling patterns → go-error-reviewer handles this
  • Performance → go-performance-reviewer handles this
  • Code style → go-quality-reviewer handles this
  • Test quality → go-test-reviewer handles this

Why No Bash Tool

This agent intentionally lacks the Bash tool. Logic review is pure reasoning over code structure — running tools would add noise without value. You read code and reason about its correctness.

Output

Return your findings in the format specified by the go-logic-review skill. Use the LOGIC- prefix for finding IDs. If no logic issues found, explicitly state "No logic 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).

Changes

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-logic-reviewer is an agent published in the GitHub repository johnqtcg/awesome-skills (30 stars, last pushed today), licensed MIT. It adds 81 tokens to every session and 536 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.
