EAP — Efficient Agent Protocol. Compress agent tokens at all three membranes: input (Context), working (Runtime), output (Signal). MIT, self-contained, honest claims.
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.
52 critical findings reported by cisco-skill-scanner, agent-audit-kit, 47 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
Claude Skills install to a single target, no runtime picker.
nerlo install -- eap-protocol
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- eap-protocol ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
5 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 217 findings across every scanner that examined this package. 5 of 52 findings rated critical by their scanner were among the dismissals.
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.
18 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.

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.

Critical shell execution and command injection risks identified.
The artifact exhibits critical vulnerabilities related to shell execution and command injection. Specifically, `COMMAND_INJECTION_EVAL` and `COMMAND_INJECTION_JS_CHILD_PROCESS` findings are present in `/repo/bin/eap-install.mjs`, `/repo/bin/eap.mjs`, `/repo/bin/lib/update.mjs`, and `/repo/layers/eap-lean/bench/correctness.cjs`. An additional critical finding, `AAK-MCP-015`, is noted in `layers/eap-lean/bench/agentic/tasks.py`. These capabilities could allow arbitrary code execution within the environment where the artifact operates.
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.
