go-dependency-audit

go-dependency-audit is a skill for Claude Code from eduardo-sl/go-agent-skills. It costs 0 tokens per session (1,616 once invoked), scanned A, original, MIT.

A checklist for reviewing Go dependencies—the external libraries and tools a project relies on—and keeping the module files tidy. It includes vulnerability checks, dependency cleanup, and checks for unsafe local replacements.

In plain words
What is it for?
Use it before commits and in continuous integration to scan dependencies, run govulncheck, tidy go.mod and go.sum, and inspect replacement directives.
Why use it?
It reduces the risk of shipping known security problems, unused libraries, stale dependency files, or accidental links to local code.

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-dependency-audit 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.

The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Go Dependency Audit

Every dependency you add is code you don't control but are responsible for. Audit ruthlessly.

1. Vulnerability Scanning

govulncheck (official Go tool):

# Install
go install golang.org/x/vuln/cmd/govulncheck@latest

# Scan project
govulncheck ./...

# Scan binary
govulncheck -mode=binary ./cmd/api-server

govulncheck checks against the Go vulnerability database and reports only vulnerabilities that actually affect your code paths — not just transitive deps you never call.

Run this in CI. No exceptions.

Additional scanning:

# Nancy (Sonatype OSS Index)
go list -json -deps ./... | nancy sleuth

# Trivy (container + deps)
trivy fs --scanners vuln .

2. go.mod Hygiene

Check for unused dependencies:

go mod tidy
git diff go.mod go.sum  # any changes = deps were stale

go mod tidy MUST be run before every commit. Add to CI:

go mod tidy
git diff --exit-code go.mod go.sum

No replace directives in committed code:

// ❌ Bad — committed replace directive
replace github.com/foo/bar => ../local-bar

// ✅ Acceptable — in monorepos with workspace
// go.work handles this instead

Exception: temporary replace for bug fixes with a comment and linked issue:

// TODO(#1234): remove after upstream merges fix
replace github.com/foo/bar => github.com/myorg/bar v0.0.0-fix

Verify checksums:

go mod verify

This confirms that downloaded modules match their expected checksums. Failures indicate supply-chain tampering.

3. Dependency Evaluation Criteria

Before adding any dependency, evaluate:

Criterion Check
Maintenance Last commit < 6 months? Active issue responses?
Popularity Stars/forks alone mean nothing. Usage in production projects matters.
License Compatible with your project? MIT/Apache/BSD preferred.
Size Does it pull in 50 transitive deps for one function?
Alternatives Can you do this with stdlib in < 50 lines?
API stability Is it v1+? Does it follow semver? Frequent breaking changes?
Test coverage Does the project have meaningful tests?

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-dependency-audit is a skill published in the GitHub repository eduardo-sl/go-agent-skills (71 stars, last pushed 24d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,616 tokens. 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.
