GOPost: Skill for Claude Code

.agents/skills/golang-testing/SKILL.md

golang-testing is a skill for Claude Code from berksunduri/GOPost. It costs 115 tokens per session (3,447 once invoked), scanned A, original, no licence file.

A guide to writing and reviewing production-oriented tests in Go, including tests that check many input cases and tests that explore unexpected inputs.

In plain words
What is it for?
Creating table-driven tests, suites, mocks, fuzz tests, fixtures, parallel tests, snapshots, integration tests, coverage checks, and Go test automation.
Why use it?
It helps you select suitable testing techniques and catch issues such as races, leaked goroutines, incomplete coverage, and broken integrations.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is berksunduri/GOPost's own configuration. It tells Claude Code how to work on GOPost itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything GOPost configures →

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

golang-testing 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 10d 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 ships with it

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.
