description: >
  Design or audit a repo-local markdown knowledge graph with wiki links,
  source-code backlinks, drift checks, and searchable sections. Use when
  AGENTS.md/CLAUDE.md is too flat for a large codebase or when a custom
  harness needs durable structured project memory.

lat.md Knowledge Graph

Purpose

Turn durable project knowledge into linked markdown files that agents can search, cite, and keep synchronized with code.

When to Use

• One root instruction file is too large or hides domain decisions.
• Agents repeatedly rediscover the same architecture or business rules.
• Test intent needs explicit specs linked to test code.
• A custom harness needs persistent memory outside conversation history.

Design Pattern

1. Create a repo-local knowledge directory such as `lat.md/` or `docs/knowledge/`. 2. Split pages by durable concepts: architecture, domain rules, workflows, interfaces, test specs, and operational constraints. 3. Link concepts with `[[wiki links]]`. 4. Link knowledge pages to source symbols or files. 5. Add code backlinks such as comments or metadata where the code implements a documented rule. 6. Add a check that fails on broken links, missing backlinks, stale indexes, or test specs without code mentions.

ctx Fit

Use this alongside ctx's LLM-wiki when a project needs its own local memory graph. ctx recommends skills/MCPs/agents from its catalog; the repo-local graph stores project-specific facts that should not live in the global catalog.

Quality Bar

• Page titles and section anchors are stable.
• Links resolve both ways where needed.
• Code backlinks are narrow and reviewable.
• Checks run in CI before merge.
• Sensitive facts stay out unless the repo already allows them.
• The graph explains current behavior, not a speculative roadmap.
