Memory

Skill Neznakometz/StackForge/core/skills/memory

The agent's memory between sessions — context management (L1) and checkpoints (L2). Apply when the context fills up, when moving to a new chat, and when closing a session.From its SKILL.md

Memory — L1 (context) + L2 (checkpoints)

L3 (durable/SQLite) and the rolling log (Layer 0.5) are in a separate set, storage (/plugin install storage@stackforge), installed when persistent memory is needed. Here — L1+L2.

L1 — active context

Watch the fill level of the context window. At 40% — propose /compact. Never let it reach auto-compact at 95% (quality degrades).
/compact: a brief summary of progress (task, done, remaining) → continue.
/convolife: estimate the % of context filled, report what's left.
/clear: a full wipe — only when the topic is fully closed.

L2 — checkpoints

/checkpoint — before every chat close. Creates Sessions/checkpoints/YYYY-MM-DD-checkpoint.md: ## What was done (specifics: paths, numbers) · ## Key decisions (why this way) · ## Not finished (the next step).
Auto-checkpoint: a task spanning 3+ files or 10+ steps → write progress to Sessions/tmp/progress-<slug>.md every exactly 10 tool calls; delete it on completion.
/newchat: checkpoint → "start a new session".

Injection order for a new session (top to bottom)

[Memory] (key facts) → [Previous session] (the last checkpoint) → the user's message.

Rules

Temporary (task details) → only L2, not into long-term memory.
Permanent (patterns, paths, architecture) → L3, if enabled; otherwise into agent-memory.md.
Replace stale entries, don't accumulate contradictions.
PROGRESS.md is maintained by the orchestrator (task-loop), the checkpoint — more detailed, for recovery.
