Security best practices for building and reviewing software, web apps, APIs, and infrastructure. Use whenever writing, designing, modifying, or auditing code — especially anything that handles user input, authentication, authorization, sessions, secrets, cryptography, databases, file uploads, network/HTTP requests, APIs, LLM/AI features, realtime/WebSockets, payments, PII, deployment/cloud/containers, or when reusing/pasting code (including AI-generated or copied Stack Overflow snippets) — to prevent vulnerabilities (injection, XSS, SSRF, CSRF, IDOR/broken access control, auth flaws, secret leakage, prompt injection, misconfiguration) by design rather than patching them later. Also use for security reviews, threat modeling, and pre-ship hardening.
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 -- 'siam-hossain9/secure-development-skill (secure-development)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'siam-hossain9/secure-development-skill (secure-development)' ~/.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 74 findings across every scanner that examined this package.
Not reviewed is not the same as clean. Those 1 finding stand exactly as their scanners reported them, at full severity, as they would have without this review.
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.

Artifact has high-severity findings for shell execution, credential exposure, and data flow.
The artifact contains high-severity findings indicating potential for shell execution during installation, as well as credential access and data flow issues within its code. Specifically, connection strings are present in '/repo/plugins/secure-development/skills/secure-development/references/SKILL.md'. Additionally, multiple instances of pipeline taint flow are identified across various reference files, including 'SKILL.md', 'dependency-and-supply-chain-security.md', 'infrastructure-cloud-and-container-security.md', and 'secure-sdlc-and-devsecops.md'.
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.
Showing 25 of 39; the rest are in the per-scanner reports above.
