Loading the registry…
A lightweight workflow engine for CI/CD pipelines, data processing, and DevOps automation — define tasks in YAML, run anywhere
The publisher performed an authenticated act of publication — proving control of a namespace in the official MCP registry, or appearing in a first-party catalogue an operator curates. That establishes WHO published it. It is not a security finding, and attested artifacts carry Flagged verdicts too.
2 critical findings reported by cisco-skill-scanner. The composite score alone does not reflect this — read the per-scanner reports below.
github: https://github.com/orieg/yaml-workflow, 95 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- yaml-workflow
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 61 findings across every scanner that examined this package. None of the 2 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.
25 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.
Rules: SOCIAL_ENG_VAGUE_DESCRIPTION, MANIFEST_MISSING_LICENSE, MANIFEST_INVALID_NAME · Files: /repo/.github/SKILL.md, /repo/docs/SKILL.md, /repo/.github/ISSUE_TEMPLATE/SKILL.md and 8 more · reported by cisco-skill-scanner
7 CI or editor configuration — The match is in build, CI or editor configuration, confirmed by our own check to be outside the installed artifact.

4 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.

1 AAK-ANTHROPIC-SDK-001
Artifact contains critical command injection vulnerabilities and high-severity risks.
The artifact includes critical command injection vulnerabilities in `/repo/src/yaml_workflow/tasks/python_tasks.py`, allowing for shell execution. It also uses a dependency with a known high-severity vulnerability (CVE-2026-52869) and has a potential DNS rebinding issue identified in `pyproject.toml`. Furthermore, the artifact exhibits undeclared network egress and uses an Anthropic SDK in `src/yaml_workflow/mcp_server.py`, which may involve credential access or data handling.
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.
