Architect analysis for rewrite/migration: produces structured architecture artifacts plus global prose research views (project-structure, tech-stack, data-model) for planning, implementation, feature-inventory, and gates. This is the single architect task. Triggers: "analyze architecture", "analyze existing application", "analyze the codebase", "codebase architecture analysis", "analyze for migration", "prepare migration analysis", "produce migration artifacts", "analyze before rewrite". NOT for: greenfield projects, pure syntax/version migrations (Python2→3, Java 8→17 — no paradigm shift), runtime validation (use runtime-validation), infrastructure/deployment analysis (use analyzing-operations), feature inventory/spec writing (use feature-inventory).
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.
21 critical findings reported by cisco-skill-scanner, 3 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 -- 'microsoft/github-copilot-modernization (analyzing-architecture)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'microsoft/github-copilot-modernization (analyzing-architecture)' ~/.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 304 findings across every scanner that examined this package. 18 of 21 findings rated critical by their scanner were among the dismissals.
Not reviewed is not the same as clean. Those 272 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.
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.
Rules: COMMAND_INJECTION_JS_CHILD_PROCESS · Files: /repo/plugins/github-copilot-modernization/agents/hook/scripts/sendTelemetry.test.js · reported by cisco-skill-scanner
2 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.
Rules: SOCIAL_ENG_VAGUE_DESCRIPTION, MANIFEST_MISSING_LICENSE · Files: /repo/plugins/github-copilot-modernization/docs/SKILL.md · reported by cisco-skill-scanner
1 CI or editor configuration — The match is in build, CI or editor configuration, confirmed by our own check to be outside the installed artifact.
Rules: AAK-MARKETPLACE-001 · Files: .github/plugin/marketplace.json · reported by agent-audit-kit
The model could have called any of these a false positive and did not.

272 The model called these false positives and our own check did not agree, so the dismissal was refused.

Critical path traversal and sensitive data handling risks identified.
The artifact contains critical path traversal vulnerabilities in `project-decomposition/scripts/decompose.py`, potentially allowing unauthorized file system access. Critical and high severity findings also indicate sensitive data handling or credential access risks within `building-java-knowledge-graph/scripts/build_knowledge_graph.py`. These capabilities require careful review due to the potential for unintended data exposure or system compromise.
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.
