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 | $0.00097 | $0.01860 |
| Opus 5.5 | $0.00039 | $0.00744 |
| Sonnet 5.5 | $0.00019 | $0.00372 |
| Haiku 4.5 | $0.00010 | $0.00186 |
Grade A, and why
golang-stretchr-testify 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 23d 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

golang-stretchr-testify is a skill published in the GitHub repository aiskillstore/marketplace (436 stars, last pushed today), with no licence file. It adds 97 tokens to every session and 1,860 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-09-24.

go-testing-with-testify
Write, review, or harden Go tests using stretchr/testify assert, require, mock, or suite. Use for assertion choice, test doubles, subtests, concurrency, and flake triage in an existing Go test setup. Use coding-guidance-go for production code or non-testify tests and tester-mindset for test strategy without concrete…
unit-test
A Go testing workflow for writing unit tests: small tests that check individual functions or components. It supports table-driven cases, where many inputs and expected results are organised in one test, and subtests.
fuzzing-test
A Go testing guide for generating fuzz tests, which repeatedly try varied inputs to find crashes and unexpected behavior. It first checks whether the code is suitable for fuzzing.
go-testing-quality
Use when writing or reviewing Go tests, adding coverage, benchmarking, or profiling a Go program. Not for CI/lint wiring (go-tooling-security) or non-Go tests.
test-go
Write, review, and improve Go test code for this project. Use whenever generating, reviewing, or modifying Go tests - including when invoked by the Tester agent, the /test prompt, or any test-related request. Covers table-driven tests, subtests, t.Parallel(), test helpers with t.Helper(), error assertions via…
go-test
When the user wants to design, implement, debug, or optimize Go tests using the standard testing package, testify, and related Go ecosystem libraries. Use when the user mentions "go test," "table-driven tests," "t.Run," "subtests," "testify," "require / assert," "go test -race," "go test -bench," "go test -fuzz,"…
