Session Memory Manager
Manages the three tiers of agent memory in an Agentic OS environment.
Prerequisites, dependencies, and trigger examples are in references/detailed-reference.md —
this skill requires the Agentic OS to be initialized first (os-init).
Memory Tiers
| Tier | File | Written By | When Loaded |
|---|---|---|---|
| Auto-memory | MEMORY.md |
Claude automatically | Every session (Anthropic native) |
| Long-term facts | context/memory.md |
You (curated) | @imported in CLAUDE.md |
| Session logs | context/memory/YYYY-MM-DD.md |
Agent at session close | On demand |
Execution Flow
Execute these phases in order. Do not skip phases. Full detail (templates, dedup protocol,
size-limit enforcement, survey questions) for each phase is in references/detailed-reference.md.
Phase 0: Intent Emission (Event Bus)
Before taking any actions, publish your intent:
python context/kernel.py emit_event --agent os-memory-manager --type intent --action promote_memory
Phase 1: Acquire OS State and Lock
- Update OS state:
active_agent os-memory-manager,mode memory-gc,memory_gc_due false. - Acquire the lock:
python context/kernel.py acquire_lock memory. If it fails, abort. - Ask the user to confirm session scope: main task/goal, architectural decisions, tricky bugs solved, skills updated, open next steps.
Phase 2: Write the Dated Session Log
Write to context/memory/YYYY-MM-DD.md using today's date, per the template in
references/detailed-reference.md.
Phase 3: Preserve Test Registry Artifacts
Never archive/skip context/memory/tests/registry.md; preserve closed scenario files for 90
days before archiving; promote confirmed test findings not already in context/memory.md; add
"DO NOT RE-TEST" entries for falsified hypotheses. Full protocol in references/detailed-reference.md.
Phase 4: Promote to Long-Term Memory
Apply the promote/skip decision (ephemeral state and open tasks → skip; system facts, commands,
style rules, architectural decisions → promote). Before promoting, read context/memory.md and
the last 10 MEMORY.md entries, run dedup/conflict detection, and follow the Safe Write Protocol
(git stash + diff preview + post-write verification). Full dedup/conflict/ID protocol and both
fact-format options are in references/detailed-reference.md.
Phase 4b: Enforce Memory.md Size Limits
Check wc -c context/memory.md; if over 50000 bytes, merge/prune redundant facts or archive the
oldest ~200 lines to context/memory/archive/YYYY-MM.md. Full steps in references/detailed-reference.md.
Phase 5: Self-Assessment Survey (MANDATORY)
Before releasing the lock, complete the Post-Run Self-Assessment Survey
(references/memory/post_run_survey.md) and save to
context/memory/retrospectives/survey_[YYYYMMDD]_[HHMM]_os-memory-manager.md. Emit
--type learning --action survey_completed on completion. Full survey questions in
references/detailed-reference.md.
Phase 6: Confirm with User and Release Lock
Show a completion summary, emit the success result event, then run
python context/kernel.py release_lock memory. Full format in references/detailed-reference.md.
