Deep Search

Core Principle

• Separate direction from evidence.
• Direction tools propose where to look: mcp__perplexity__perplexity_ask, mcp__deepwiki__ask_question.
• Evidence tools prove claims: official docs, release/tag metadata, source code at pinned commit/tag.
• Two-evidence gate: every key claim needs at least two independent evidence classes, and at least one must be primary (docs/source/release).
• Version anchoring is required for "latest", "current", "changed", "deprecated", and "not supported" claims: include explicit version/tag and date.

Evidence Hierarchy

• Tier A (primary): official docs, release notes/changelog, source code at pinned tag/commit.
• Tier B: maintainer issues/PR discussions.
• Tier C: community evidence (Reddit/forums/blogs/Stack Overflow).
• Tier D: LLM synthesis (perplexity, deepwiki) as hypothesis only.
