Brownfield extraction pack for forgeplan — turns legacy code + docs into a structured forgeplan graph. Ships 12 extraction skills (ubiquitous-language, use-case-miner, intent-inferrer, invariant-detector, causal-linker, hypothesis-triangulator, interview-packager, scenario-writer, kg-curator, canonical-reproducer, reproducibility-validator, rag-packager), 2 orchestration playbooks (extract-business-logic, phase-transitions), 3 integration recipes (autoresearch hooks, forgeplan MCP additions, RAG export), 5 mappings (c4-to-forge, ddd-to-forge, madr-to-forge, obsidian-to-forge, autoresearch-to-forge), templates, examples, and methodology docs. Implements two-tier extraction (Factum vs Intent) with confidence taxonomy and ADI cycle. v1.4.0: Sprint V (PRD-048) — discover agent migrated from standalone to plugin (canonical Profile A pattern, MCP-first 7-phase procedure, 9 brownfield MCP primitives wired).

discover

/discover

EN: Brownfield codebase onboarding — analyzes existing projects via canonical 7-phase MCP discovery protocol with tiered source priority (code > extracted > docs). Wraps forgeplan_discover_* MCP surface. Produces structured forgeplan graph (NOTE/PRD/PROBLEM/EVIDENCE artifacts) covering tech stack, modules, data stores, infra, git history, tests, docs synthesis. RU: Brownfield агент для онбординга легаси кодбейзов через канонический 7-phase MCP discovery протокол. Оборачивает forgeplan_discover_* MCP. Производит структурированный граф NOTE/PRD/PROBLEM/EVIDENCE по фазам tech stack / modules / data / infra / git / tests / docs. Triggers: "discover codebase", "brownfield onboarding", "map existing project", "проанализируй проект", "исследуй кодбейз", "discover brownfield", "tech stack discovery", "module map", "extract from legacy code", "/discover"
