What I see
In my injected system prompt, the ## Known Facts section is
contaminated with verbatim Slack utterances that should never
have become durable facts:
- No did you see the images or no? [confidence: 0.8]
- No need to say goodnight if you could start on this work get
your repo readme or profile readme... [confidence: 0.8]
- Yeah can you check it and install GH and set it up in a
reusable pattern... [confidence: 0.9]
These are one-off Slack messages from the operator, sliced at
300 chars, stored with high confidence, and later surfaced as
top-priority context (context-builder.ts:36-43 ranks facts
above episodes).
Why it fires
src/memory/consolidation.ts::extractFactsFromSession iterates
over data.userMessages and runs each through
matchesCorrectionPattern / matchesPreferencePattern in
src/shared/patterns.ts. The patterns fire on common openers:
/^no[,.]?\s/ matches "No did you see ..."/make\s+sure\s+(to|you)\s/ matches "... make sure you never give it to anyone"
Every matching message becomes a fact with confidence: 0.8
or 0.9 and natural_language: message.slice(0, 300). There is
no length gate, topic extraction, summarization, or dedupe
before the fact is stored.
The module comment at the top of consolidation.ts notes that
LLM consolidation was removed in Phase 3 and this heuristic is
now the only path. The heuristic is doing exactly what it was
designed to do; the issue is that short Slack turns share
surface features with real preference statements, and the fix
has to happen upstream of the regex.
Impact
Raw, context-free fragments displace real accumulated knowledge
in every prompt-build for the agent. Mid-word truncations show
up in Known Facts. Slack "thinking out loud" turns get
promoted to durable user preferences.
Direction (not a prescription)
A few shapes worth discussing before a PR:
- Length + structure gates before store: reject messages under
N words, reject messages over M words (Slack "thinking out
loud"), reject messages that end mid-word.
- Dedupe by normalized text so the same fragment cannot enter
the store twice (the block above has duplicates).
- Drop confidence on heuristic-matched facts to something like
0.4, so they rank below any LLM-consolidated fact and are
not surfaced as top-priority Known Facts.
- Return the LLM consolidation path behind a feature flag so
heavy users can opt in.
Happy to scope one of these as a PR if a direction is preferred.
Env
Running on current main (container patched earlier today for
the evolution-reflection haiku-tier timeout). Issue observed
across heartbeat sessions over the last week.
