Idiomatic Go: interfaces, error handling, concurrency, testing, package layout, and debugging. Use when the user writes, reviews, or debugs Go code, or asks any open Go question that doesn't fit a more specific child skill. SKIP for Go performance/profiling work (use go-profiling-optimization) and explicit Gopher Guides training/API requests (use gopher-guides).
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
14 critical findings reported by cisco-skill-scanner. The composite score alone does not reflect this — read the per-scanner reports below.
This artifact ships from 2 sources and their verdicts differ. The worst is github (Flagged). Installing from a cleaner source does not mean the others are safe — check the source you actually install from.
github: https://github.com/gopherguides/gopher-ai, 243 findings
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'gopherguides/gopher-ai (go)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'gopherguides/gopher-ai (go)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
6 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 238 findings across every scanner that examined this package. None of the 14 findings rated critical by their scanner were dismissed.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
23 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

3 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.

3 CI or editor configuration — The match is in build, CI or editor configuration, confirmed by our own check to be outside the installed artifact.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

13 AAK-MARKETPLACE-001
Files: .claude-plugin/marketplace.json, .agents/plugins/marketplace.json
Artifact contains critical command injection and execution risks.
The artifact contains multiple critical findings related to potential command injection and shell execution in various markdown files within `plugins/go-dev` and `plugins/llm-tools`. Additionally, high severity findings indicate potential network egress of secrets from Python code and shell execution during installation. These capabilities could allow arbitrary code execution and data exfiltration.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
