  • memofs_agent_session_appendAppend MemoFS Agent Session File

    Append to an allowed working/ or output/ file in an AgentFS session.

  • memofs_agent_session_completeComplete MemoFS Agent Session

    Extract, checkpoint, push, and optionally persist durable memory from an AgentFS session. Set `outcome` explicitly — the `"success"` default is for backward-compatibility only and is NOT recommended for new callers. `outcome: "success"` + `extractDurableMemory: true` promotes durable memory to notes.md and auto-cleans `working/` (output preserved). `outcome: "failure"` never promotes durable; pass `ephemeral: true` to clean `working/` + `output/`, or omit to preserve them as failure audit-trail. `outcome: "aborted"` preserves the entire workspace for resume via a future `complete({outcome:"suc…

  • memofs_agent_session_extractExtract MemoFS Agent Session Memoryread-only

    Extract summary, durable memory, follow-ups, errors, and changes from an AgentFS session.

  • memofs_agent_session_readRead MemoFS Agent Session Fileread-only

    Read one AgentFS session file.

  • memofs_agent_session_startStart MemoFS Agent Session

    Create an AgentFS-backed MemoFS session workspace and return paths/resources for coding agents.

  • memofs_agent_session_writeWrite MemoFS Agent Session File

    Write an allowed working/ or output/ file in an AgentFS session.

  • memofs.consolidateConsolidate MemoFS Graph Memory

    Run a memory consolidation pass over the local graph: merge duplicate entities and retire facts superseded by a `supersedes` edge. The audit trail is preserved — nothing is deleted, only marked `deprecated`. This is the second half of v1 intelligence: extraction grows the graph, consolidation keeps it tidy. Pass apply=false to preview the plan without persisting. Hosts should authorize this write when apply is true.

  • memofs.contextBuild MemoFS Agent Contextread-only

    REQUIRED at the start of every task: build task-ready memory context by combining core memory, recent memory, and recall. MemoFS is the single source of truth for project identity, architecture, constraints, and decisions — ALWAYS call this before planning or writing code so your work adheres to stored memory. The returned text already tells you how to act on it. Read-only. By default returns a COMPACT briefing (~6kb): core memory in full, the top entities and a few recall fragments, plus an `expandable` list. Each expandable entry names a section (entities/recall/recent/notes), how many more…

  • memofs.recallRecall MemoFS Memoryread-only

    Semantic + lexical memory search. Use this proactively — before answering, when unsure, or when a fact might already be known. Phrases it understands: synonyms and paraphrases, not just exact keywords. Call it instead of guessing or re-deriving facts. Read-only; never modifies memory. Each returned item may carry an optional `anchor` (the code file + hash this fact is bound to) and a `stale` flag (true when the anchored file changed since write — re-verify before trusting).

  • memofs.rememberRemember MemoFS Memory

    Persist a durable, high-signal fact so future agents benefit. Quality bar: one fact per note, and only facts that would change a future task's behavior — root causes, contracts, conventions, decisions. Use durable kinds (decision/constraint/goal/preference/reference) for facts; note/summary are transient scratch that is never indexed. Before writing, recall what is already stored and update or supersede an existing memory instead of appending a near-duplicate — the runtime skips writes that near-duplicate an indexed memory. Never record transcripts, step logs, or verification output ("tests pa…
