Palinode Memory

Palinode stores typed memory as git-versioned markdown files with hybrid search (BM25 + vector). This skill provides procedural guidance for using Palinode's tools effectively.

Core Tools

Memory Types

Use the right type when saving:

• PersonMemory — facts about a person (name, role, preferences, context)
• Decision — architectural/product decisions with rationale
• ProjectSnapshot — current state of a project (milestone, blockers, next)
• Insight — generalizable lessons learned (applies beyond current project)
• ActionItem — follow-up task with owner and deadline

Search Effectively

Palinode uses 4-phase injection — you don't always need to search manually:

1. Core files (core: true) are always injected at session start
2. Topic search runs on every turn automatically
3. Associative recall expands entity mentions automatically
4. Triggers fire when registered contexts match

Only call palinode_search explicitly when you need something specific not surfaced by injection, or when the user asks "what do I know about X?"

Saving Memories

Guidelines:

• Save decisions with rationale — not just what was decided, but why
• Save people context when you learn preferences, constraints, or relationships
• Save insights when a lesson applies broadly (not just to one task)
• Don't save raw conversation transcript — save the distilled fact

Example save calls:

palinode_save(
  content="Alice and Bob are co-founders, 3-year gap in joining. CEO role is shared.",
  type="PersonMemory",
  entities=["person/alice", "project/my-app"]
)

palinode_save(
  content="Curation > volume for training data. 90 curated samples >> 1,623 raw.",
  type="Insight",
  entities=["project/my-app"]
)

Triggers

Register an intention when you want a memory to auto-surface in future turns:

palinode_trigger(action="add", description="training data curation",
               memory_file="insights/curation-over-volume.md", threshold=0.72)

Triggers fire when the user's message semantically matches description. Good for:

• "whenever we talk about training data, surface the curation insight"
• "when Alice's design decisions come up, surface the architecture relationships"

Git Tools

Use these when the user asks about memory history:

• palinode_diff — what changed in the last N commits for a file
• palinode_blame — who/when each section was written
• palinode_history — file change history with diff stats and rename tracking
• palinode_rollback — revert a file to a previous state

Consolidation

Weekly compaction runs Sunday 3am UTC via cron. To run manually:

palinode_consolidate(dry_run=True)   # preview what would change
palinode_consolidate(dry_run=False)  # apply operations

Operations: KEEP (no change), UPDATE (merge new info), MERGE (combine duplicates), SUPERSEDE (replace fact), ARCHIVE (move to history).
