compile-knowledge

Durable knowledge is worth keeping as many small, interlinked markdown files, compiled over time and surfaced through an index — not as one giant doc, a chat log, or a one-off file that rots. This skill makes compiling consistent so your agent gets smarter over time instead of relearning the same things.

Where it goes — pick the right store

• Agent memory (default, always available): your .claude/.../memory/ folder with MEMORY.md as the index. This is the per-agent store and it survives restarts — it's the karpathy "external memory" that keeps you sharp across sessions. Governed by the memory rules already in your system prompt — follow them. For most agents this is the only store you need.
• Shared wiki (only if you work as a team): a wiki/ folder in your project with a wiki/index.md. For knowledge the whole team benefits from — domain facts, research findings, reference material multiple agents would re-derive. Skip this entirely if you're a solo agent; don't manufacture team ceremony.
