+# CLAUDE.md
+
+Magellan is an enterprise knowledge discovery plugin. It extracts structured
+knowledge from collected materials and builds a queryable knowledge graph.
+
+## Commands
+
+- `/magellan` — Run the discovery pipeline or show status
+- `/magellan:add <path>` — Add a file or directory
+- `/magellan:add --correction "..."` — Record a verbal correction
+- `/magellan:ask <question>` — Query the knowledge graph
+
+## Four Principles
+
+1. Every fact traces to a source document. Nothing is invented.
+2. Contradictions and open questions are the primary output, not a side effect.
+3. Nothing is silently skipped. Every file gets a recorded disposition.
+4. The model does the heavy lifting. Humans steer and correct.
+
+## Key Skills
+
+- `skills/file-conventions/` — JSON schemas for all KG file types. Read this
+  before writing any file to `.magellan/`.
+- `skills/ingestion/` — Fact extraction rules and language guides for legacy code.
+- `skills/pipeline-review/` — Quality gate criteria. Run after every pipeline step.
+
+## Output Location
+
+All outputs go in `<workspace>/.magellan/`. See the file-conventions skill for
+the complete directory layout and JSON schemas.

+# Connectors
+
+Magellan is a **self-contained** knowledge discovery plugin. It does not require
+connections to external SaaS tools to function — all knowledge extraction, graph
+building, and querying happens locally using the files in your workspace.
+
+## Optional Tool Integrations
+
+While the core pipeline is self-contained, you can optionally connect external tools
+to enhance Magellan's workflows:
+
+| Category | Use Case | Example Tools |
+|----------|----------|---------------|
+| ~~project-tracker~~ | Route open questions to your team as tickets | Jira, Linear, Asana, GitHub Issues |
+| ~~chat~~ | Send contradiction summaries to team channels | Slack, Microsoft Teams |
+| ~~knowledge-base~~ | Fetch referenced documents from team wikis | Confluence, Notion, Guru |
+
+These integrations are **tool-agnostic** — any MCP server in the category works.
+Add the relevant MCP servers to your `.mcp.json` to enable them.
+
+## No Required Connectors
+
+Unlike plugins that depend on external data sources, Magellan works entirely from
+local files. Point it at a folder of collected materials (code, documents, transcripts,
+diagrams) and it builds the knowledge graph from those files directly.
+
+## System Requirements
+
+Magellan has no system requirements beyond Claude Code. It reads files directly
+using Claude's built-in capabilities — no external tools needed.
+
+> **Note:** Claude does not yet natively read DOCX, PPTX, or XLSX files. Until it
+> does, convert these to PDF before adding them to your workspace.

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+# Magellan
+
+Enterprise knowledge discovery. Point Magellan at a folder of collected materials —
+code, documents, meeting transcripts, API specs, diagrams — and it builds a structured,
+queryable knowledge graph organized by business domain. Contradictions and open questions
+are surfaced as primary outputs, not side effects.
+
+## Quick Start
+
+```bash
+claude plugin install magellan@knowledge-work-plugins
+```
+
+```
+/magellan                              Run the discovery pipeline
+/magellan:add /path/to/document.pdf    Add a file
+/magellan:add --correction "..."       Record a verbal correction
+/magellan:add --resolve c_001 "..."    Resolve a contradiction
+/magellan:add --resolve oq_003 "..."   Answer an open question
+/magellan:ask How does billing work?   Query the knowledge graph
+```
+
+## What You Get
+
+```
+.magellan/
+  contradictions_dashboard.md      ← Contradictions & open questions (the priority)
+  contradictions_dashboard.html    ← Print-friendly version
+  onboarding_guide.md              ← Briefing for new team members
+  diagrams/                        ← C4 architecture diagrams (Mermaid + PlantUML)
+
+  domains/<domain>/
+    facts/                         ← Atomic facts from source documents
+    entities/                      ← One file per knowledge graph entity
+    relationships.json             ← How entities connect within this domain
+    summary.json                   ← Plain language domain narrative
+    contradictions.json            ← What disagrees
+    open_questions.json            ← What's unknown
+    deliverables/                  ← Business rules, DDD specs, API specs, contracts
+```
+
+## How It Works
+
+The pipeline runs in two phases with quality gates after every step:
+
+**Phase 1 — Discovery**: Read files → extract atomic facts → build entities and
+relationships → detect contradictions → link across domains → summarize each domain
+→ generate onboarding guide, dashboard, and C4 diagrams.
+
+**Phase 2 — Design**: Formalize business rules (HARD / SOFT / QUESTIONABLE) → generate
+DDD specs → implementation contracts → export rules as DMN, JSON, CSV, Gherkin →
+generate OpenAPI and AsyncAPI specs.
+
+Every fact traces to a source document with an exact quote. Nothing is invented.
+On subsequent runs, only new and modified files are processed.
+
+## Input Files
+
+Magellan reads anything Claude can read — text, code, markdown, CSV, JSON, YAML, XML,
+PDF, images, and meeting transcripts.
+
+> **Note:** Claude does not yet natively read DOCX, PPTX, or XLSX files. Until it
+> does, convert these to PDF before adding them to your workspace.
+
+Includes 12 language guides for legacy systems (RPG, COBOL, CL, DDS, JCL, CICS,
+Assembler/370, NATURAL/ADABAS, IDMS, Easytrieve, PL/I, REXX) that improve extraction
+precision. Add your own for proprietary languages.
+
+## Installation
+
+```bash
+claude plugin install magellan@knowledge-work-plugins
+```
+
+Requires only Claude Code. No Python, no build steps, no system dependencies.
