cognition

Cognition session-end memory — facts regex-extracted from your messages at session end, stored in a local SQLite queue and JSON log under one repo label, with fetch-first merge, per-entry provenance, and budgeted prefetch (tools: cognition_search, cognition_status, read-only cognition_dream). Disclosure — saves verbatim excerpts (up to 400 chars) of your own messages that match preference/decision phrases in plain local files under HERMES_HOME/cognition/ (SQLite queue, JSON commit log) and re-injects them into later prompts sent to your model provider; the author name is read from ~/.gitconfig; the plugin makes no network calls of its own.

Cognition memory provider

Session-end durable memory for Hermes: one active provider. Facts are
regex-extracted from your messages at session end, stored in a local SQLite
queue and JSON log under one repo label.

  • Push is fixed to session end. Turns accumulate; on_session_end
    extracts durable facts onto a SQLite FIFO queue. sync_turn persists
    nothing. Pending means unpushed (extracted, not yet committed).
  • Fetch-first merge, keep-both conflicts. Push compares against committed
    state first; a changed base keeps both versions under deterministic refs
    (cog-{sessionId}-{seq}, conflicts {ref}-conflict-{unix_ts}). Exact
    redelivery of an already-committed entry is idempotent.
  • Mandatory provenance. Every entry carries source_session, author,
    created_at, origin_repo, trace_id. archive_and_evict archives an
    entry to JSONL before removing it; nothing in this version calls it
    automatically.
  • Single-writer lock per entry id. Dream reads committed state only.
  • Prefetch budget (default 8000 tokens). Truncation order: system-pin >
    provenance > recency > salience, always with a marker.
  • Dream is read-only. cognition_dream synthesizes committed state and
    surfaces conflicts; no write-back path exists by design.

Config (DRAFT key names): memory.provider=cognition with
memory.cognition={repos, budget_tokens, queue, archive}. Setup asks for the
author identity last — the configured author is authoritative for provenance;
empty falls back to host git config user.name.

Recall injects committed facts under the token budget. Built-in memory
(MEMORY.md, USER.md) is left to Hermes core and is not mirrored here.

Layout

  • plugin.yaml — manifest; __init__.py — register(ctx)
  • provider.py — CognitionMemoryProvider (tools: cognition_search,
    cognition_status, cognition_dream)
  • queue.py — durable FIFO (retry 1m/5m/30m+jitter, 24h cap, bound 1000
    drop-oldest-with-tombstone, backlog surfacing)
  • merge.py — fetch-first push, keep-both, per-entry locks, commit log.
    The on-disk committed.json is the sole truth: every push/remove runs
    refresh → compare → write as ONE transaction under cross-instance/process
    exclusion with the per-ref lock nested inside.
  • provenance.py — mandatory provenance + eviction-preserving archive
  • budget.py — prefetch budget + truncation order + marker
  • tests/ — one acceptance test per contract condition (python3 -m unittest discover -s tests -t tests from this directory). Tests load the
    real Hermes agent.memory_provider base (installed package, PYTHONPATH
    checkout, or HERMES_AGENT_ROOT); a missing dependency fails fast with a
    deterministic error — never a silent stub.
