SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.06276 |
| Opus 5 | $0.00013 | $0.03138 |
| Sonnet 5 | $0.00005 | $0.01255 |
| Haiku 4.5 | $0.00003 | $0.00628 |
Grade A, and why
go-idioms 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.
How it starts
The opening of the file, as written. The whole thing — 778 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Go Idioms and Patterns
1. Core Philosophy
Go favors simplicity, explicitness, and readability. The language is intentionally small — resist the urge to import patterns from other languages. If it looks boring and obvious, it's probably idiomatic Go.
Scope: This file covers Go-specific coding idioms. For file layout, see
references/project-structure.md. For detailed safety, SAST, and performance patterns, seereferences/go-patterns-and-anti-patterns.md. For logging library choice, see thelogging-implementationskill. For quality commands, see thecode-idioms-and-conventionsrule.
Loading Guards: If the project has no go.mod, this skill does not apply.
2. When to Load References
| Situation | Reference to Load |
|---|---|
| Starting a new project or setting up file layout | references/project-structure.md |
Choosing packages, go.mod setup, or golangci-lint config |
references/recommended-dependencies.md |
| Writing code that handles I/O, concurrency, or user input | references/go-patterns-and-anti-patterns.md |
3. Toolchain and Go Version
Default to the latest stable Go release. As of August 2026, Go 1.24 is the baseline with the Go module system.
Key version milestones:
- 1.24+ —
go toolfor tool dependencies, swiss table map implementation - 1.23+ —
range-over-func (iterator protocol),uniquepackage - 1.22+ —
range-over-integer, loop variable per-iteration scoping (eliminates loop variable capture bugs), enhancedServeMuxwith method-based routing - 1.21+ —
log/slogstructured logging,mapsandslicesstdlib packages,sync.OnceFunc/sync.OnceValue/sync.OnceValues,min/maxbuiltins,clearbuiltin - 1.18+ — Generics, fuzz testing with
testing.F
Example go.mod configuration:
module github.com/user/project
go 1.24.0
toolchain go1.24.0
4. Error Handling
- Always return errors — never panic in library or business code
panicis reserved for truly unrecoverable states (programmer errors, nil dereference)- Use
recoveronly at top-level goroutine boundaries (middleware, server startup)
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.

go-idioms is a skill published in the GitHub repository irahardianto/awesome-agv (156 stars, last pushed 21d ago), licensed MIT. It adds 25 tokens to every session and 6,276 once invoked, about $0.0001 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.
