go-specifications

go-specifications is a skill for Claude Code from danweinerdev/claude-sdd-planner. It costs 35 tokens per session (163 once invoked), scanned A, original, MIT.

A verification checklist for Go programs, the programming language. It uses go vet, race-detection tests, and staticcheck to find suspicious code, concurrency bugs, and other correctness issues.

In plain words
What is it for?
Planning, implementing, or reviewing Go code, including projects with goroutines, channels, or shared data.
Why use it?
It catches common Go problems that may not appear during ordinary compilation or tests.

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-specifications 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 6d 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.

Go — Structural Verification

Tools

Tool When What it catches
go vet ./... Always Printf format mismatches, unreachable code, suspicious constructs
-race flag on tests Goroutines, channels, shared state Data races
staticcheck Always (if available) Additional correctness checks beyond go vet

Minimum Bar

go vet on every phase. -race when goroutines or shared state are involved.

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.
