Researcher Skill - Documentation & Fact Verification

Overview

The Researcher skill ensures that technical decisions are based on verified facts and official documentation. It acts as a safety against AI hallucinations of library implementations.

Core Capabilities

1. Fact Checking: Verify library versions via pyproject.toml, package.json, or environment checks.
2. Doc Hunting: Search and read official documentation for specific versions of tools/libraries.
3. Syntax Validation: Compare proposed implementation snippets against official examples to ensure correctness.
4. Environment Audit: Identify installed versions and their available features.

Verification Protocol

1. Version Audit: Identify the exact version of the technology in use.
2. Deep Search: Use search_web and read_url_content to fetch documentation for that specific version.
3. Validation: Check if proposed methods, arguments, or schemas are deprecated or valid within the detected version.
4. Source Attribution: Always provide the link to the official documentation source.

When to Use

• When using a third-party library or API.
• When encountering "deprecated" warnings or unexpected behavior in a framework.
• Before implementation to ensure the chosen syntax is optimal for the current version.

Constraints

• NO implementation code. Provide confirmed snippets or links only.
• DO NOT guess. If a documentation source is unavailable, state it clearly.
• Read-Only. Only fetch and report information.

Common Pitfalls

• Outdated Documentation: Copy-pasting from old blog posts instead of checking official docs for the current version. Always verify version compatibility.
• Ignoring Deprecation Warnings: "This still works" isn't good enough. Check changelogs; new versions may break APIs you're using.
• Trusting Stack Overflow: Great for ideas, terrible for truth. Always verify against official documentation and source code.
• Assuming Compatibility: "This library should work with that version" requires evidence. Check dependency specs explicitly.
• Missing Edge Cases: Official docs show the happy path. Check issues/discussions for known gotchas and workarounds.
• Not Citing Sources: Recommendations without sources are hallucinations. Every claim must have a link to official docs or source code.

Integration Points

Phase	Input From	Output To	Context
Investigation	Question about library/API	Fact verification	Research current version and features
Validation	Proposed implementation	implementer	Confirm proposed syntax matches official docs
Decision	Technology comparison	architect	Provide version-accurate comparisons for arch decisions
Prevention	Before implementation	implementer	Validate approaches against official capabilities

Outputs & Deliverables

• Primary Output: Verified documentation references, version-accurate code snippets, and source links
• Secondary Output: Compatibility notes and deprecation warnings relevant to the project's versions
• Success Criteria: All claims are backed by authoritative links and examples that match the target version
• Quality Gate: implementer or requestor review for actionable code snippets

Additional Constraints

• Technical Constraints: Avoid making implementation changes; provide exact references and examples only
• Governance Constraints: Cite official docs and avoid relying on unverified third-party blogs for critical claims
