Manage document- and website-based computer-science study with HTML capture, source-grounded summaries, tags, active-recall questions, per-source and per-section mastery, mistakes, search, and spaced review. Use when the user imports technical documents or a website, asks Codex to capture pages and turn them into memorable knowledge, wants to find or review a source or topic, requests source-grounded quizzes, or asks for a study dashboard.
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 -- 'wxhhxn/learnbyagent (study-computer-science)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'wxhhxn/learnbyagent (study-computer-science)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 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 33 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 analyzability issues and network egress detected
The artifact exhibits high analyzability issues in `/repo/web`, which may obscure its full operational scope. Multiple instances of network egress are detected, indicating data transmission capabilities. Additionally, findings related to potential prompt injection and vague descriptions warrant attention.
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.
