Guides Go channel mechanics — declare directionality in signatures (chan less than - send-only, less than -chan receive-only), let only the sender close and only when sends are done (closing is a broadcast, not cleanup), read the comma-ok / range-ends-on-close idiom so a closed channel's zero value is not mistaken for data, choose unbuffered (synchronization) vs buffered (decoupling) deliberately, use chan struct{} for pure signals, and drive select with default for non-blocking and the nil-channel trick to disable a case. Auto-invokes when writing or editing channels, chan declarations, close(), select statements, or buffered channels, and on "send on closed channel panic" / "why does this select block" / "why does my range over a channel never end" requests. The depth behind the policy root's "don't fight Go" for the communication primitive.
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.
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'ctoth/golang-skills-plugin (go-channels-select)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'ctoth/golang-skills-plugin (go-channels-select)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
3 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 219 findings across every scanner that examined this package.
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.

High-severity findings in marketplace plugin definitions.
The artifact contains high-severity findings related to marketplace plugin definitions within `.agents/plugins/marketplace.json` and `.claude-plugin/marketplace.json`. These findings indicate potential issues with how the artifact interacts with or defines marketplace components. Attention is warranted for the `AAK-MARKETPLACE-001` rule, which suggests significant risk in these configuration files.
Concern level assessed by the review: High. 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.
