Why this exists

The plugin is deterministic. The agent is not. So we separate:

  • Agent: decides what to learn (writes the spec).
  • Tool (compound_apply): validates and applies changes safely.

CompoundSpec v2

Top-level keys (all optional except schema_version):

  • schema_version: must be 2
  • auto: { reason, sessionID }

instincts

  • create[]: { id, title, trigger, action, confidence }
  • update[]: { id, confidence_delta, evidence_note }

skills

  • create[]: { name, description, body }
  • update[]: { name, description?, body }

Notes:

  • name must match ^[a-z][a-z0-9]*(?:-[a-z0-9]+)*$.
  • body is markdown without frontmatter.
  • If updating a skill: skills.update[].body must be the entire final managed body (no snippets/diffs).

docs

  • sync: boolean (refresh derived indexes/blocks)
  • blocks.upsert[]: { file, id, content }

Only upsert AI-managed blocks; do not rewrite human-owned text.

When writing markdown content inside docs.blocks.upsert[].content:

  • Use repo-root-relative paths when referencing files/dirs (no absolute paths).

changelog

  • { note }: a single sentence describing the memory delta.

Apply

  1. Draft the CompoundSpec v2 as a single JSON object.
  2. Output JSON only (no code fences, no commentary).
  3. Run compound_apply() to validate and write the memory/doc updates.
