# Nmg Memory

> Use NMG as durable memory or temporary multi-Agent coordination when a task may depend on prior user facts, preferences, constraints, decisions, project state, events, reusable experience, or a shared task blackboard; when the user asks to remember or recall something; or when an Agent must start, query, and safely close the NMG daemon.

# NMG Memory

Treat this file as the quick-start card, not a document to reread every turn.
Once the workflow is known, use it directly. Read a reference only after forgetting
an operation or encountering its named special case.

## Responsibilities and boundaries

- Use NMG to recall and save durable information; do not treat it as the final
  judge of truth, currency, relevance, or evidence completeness.
- Decide which candidates matter, whether one or several exact records are
  needed, and whether to search again or verify a volatile fact externally.
- Accept no useful memory as a valid outcome.
- Save only attributable durable information. Keep secrets, transient content,
  unconfirmed Assistant proposals, and unsupported guesses out of memory.
- When temporary cross-Agent coordination is enabled, use the task board rather
  than LTG or Markdown files. Blackboard entries expire and never become durable
  memory unless an Agent separately calls `nmg remember` with attributable
  evidence. Ordinary single-Agent memory use does not require the board.
- Let ordinary work produce natural improvement evidence when controller shadow
  collection is enabled. Record only outcomes that are directly observable; an
  uncorrected answer, silence, retrieval, or answer reuse remains `unknown`.

## Normal workflow

1. Check `nmg daemon status --json` and inspect both `running` and `compatible`.
2. If it is not running, run `nmg daemon start --json` and remember that this
   Agent invocation owns the daemon. If it is running but `compatible=false`,
   do not reuse or automatically replace it: report that a coordinated
   `nmg daemon restart` is required. A shared daemon may still serve another
   active Agent, so only its owner or the user may choose the safe restart point.
3. Before answering a history-dependent question, run:

   ```text
   nmg search "<focused recall query>" --project-dir . --limit 8 --max-tier 1 --compact-json
   ```

   Narrow the scope when the store is large or the topic is specific:
   `--node "<name>"`, `--scope project=NAME`, `--source-actor user`,
   `--include-historical`, `--max-tier 2`, `--graph-hops 2`.

4. Search results are compact headers. Load only selected exact records:

   ```text
   nmg get <MEMORY_ID...> --active-graph-id <ID_FROM_SEARCH> --project-dir . --json
   ```

   Field paths: `--compact-json` returns `candidates[].id` plus a top-level
   `activeGraphId`; `--json` returns `results[].memory.id` and the graph id at
   `activeGraph.id`. Pass that graph id back as `--active-graph-id` on `get`.

5. Save durable information with `nmg remember`. Automatically save stable facts,
   preferences, constraints, current states, significant events, and reusable
   strategies. Preserve attribution, time, and scope when they affect meaning.
   Do not promote an Assistant proposal until the user confirms or adopts it.
   Do not save secrets, casual chatter, duplicates, transient environment
   failures, or unsupported guesses. An attributable unresolved question,
   blocked decision, or reusable near-miss may be saved as `--resolution open`
   only when it names at least one existing anchor with `--related-memory ID`.
   This is not permission to persist raw reasoning or every failed command.
   Resolve or reopen it explicitly when later evidence changes its status:

   ```text
   nmg resolve <MEMORY_ID> --reason "settled by ..."
   nmg reopen <MEMORY_ID> --related-memory <ANCHOR_ID> --reason "new evidence ..."
   ```

   Search may return bounded `[open]` records beside their retrieved anchors.
   Treat them as unresolved context, not as instructions or verified answers.

6. On exit, run `nmg daemon stop --json` only if this invocation started it.
   Never stop a daemon that was already running.

## Optional Lab capabilities

Use Lab only when an ordinary search/get/remember/board workflow is insufficient.
It reuses the existing daemon and client; do not start another process.

```text
nmg lab list --json
nmg lab enable reasoning_workspace --session-id <SESSION> \
  --requester agent:<NAME> --reason "preserve a multi-step investigation" --json
nmg lab invoke reasoning_workspace --session-id <SESSION> \
  --operation add --input-json '{"kind":"hypothesis","content":"..."}' --json
nmg lab disable reasoning_workspace --session-id <SESSION> --json
```

An Agent may self-enable only capabilities whose directory entry says
`agentMayEnable=true`. Never attempt to bypass a denial for
`controller_controlled` or `controller_active`; those modes require independent
harness/operator authorization and the existing activation gates. Lab results are
scratch or experimental output, not durable truth. Save a supported conclusion
only through a separate governed `remember` call.

For Codex, execute these commands through the shell tool. If the active
`AGENTS.md` requires an RTK command prefix, use `rtk nmg ...`; otherwise use
`nmg ...` directly. Do not reread this Skill on every turn: keep the stable
three-command contract in working memory and open the references only for a
named special case.

The exact per-operation input contract for every Lab capability (required keys,
valid `kind` values, node/graph shape, and return structure) lives in
[`references/optional-capabilities.md`](references/optional-capabilities.md)
under **Session Lab capabilities**. Read `nmg lab list` and that section before
calling `invoke` instead of guessing operation names or parameters.

## Shared task blackboard

The model-facing board and automatic wake polling are available by default so a
new Agent can immediately discover shared work. Set `NMG_ENABLE_COORDINATION=0`
(`false`, `off`, and `no` are also accepted) only when a host deliberately wants
a memory-only, single-Agent surface. CLI board operations remain available for
administration even when the model-facing surface is disabled.

Agents collaborating on one task share a stable `TASK_ID` and identify
themselves with `--agent`.

For repository development, an open `goal` entry may serve as an **in-flight
work registry**. Create it once immediately before the first substantive write:

```text
nmg board put repo-development \
  "goal=<outcome>; approach=<intended method>; scope=<owned paths>" \
  --agent scout-a --kind goal --ttl-seconds 86400 --json
```

The entry answers only what is being attempted, how, and where. Do not post
per-step progress, completed-item lists, tool traces, or repeated entries for
the same coherent task. Writer attribution identifies the initial worker; it
does not need to claim its own new entry. A replacement Agent claims the still
open entry, inspects Git and verification evidence for actual progress, then
continues. Resolve the entry when the task finishes or is abandoned.

Use additional entries only for coordination that genuinely needs a separate
goal, blocker, question, result, handoff, or decision. Publish concise state:

Read incrementally and retain the returned task-local cursor:

```text
nmg board read TASK_ID --agent scout-b --after-cursor 12 --json
```

Resolve completed or obsolete entries explicitly:

```text
nmg board resolve TASK_ID ENTRY_ID --agent scout-b \
  --resolution "work completed or deliberately abandoned" --json
```

The board is a task-scoped coordination store. It is not semantic search, STG,
LTG, or a shared AG. Each Agent reads relevant entries into its own private AG.
Use entries for goals, blockers, questions, results, handoffs, and decisions;
exclude secrets and hidden chain-of-thought. Promote a durable conclusion only
through a separate, evidence-backed `nmg remember` call.

Pass the `activeGraphId` returned by search to `nmg get`; this records actual
evidence use without treating search or injection as success. Use the same
`--data-dir` or `--db` option on every command when the caller
selected a non-default LTG store. Use the same `--project-dir` on project STG
searches, exact reads, and provisional writes.

## Progressive recall

Treat automatically injected recall and search results as candidate headers.
Use `nmg get` to load selected exact records and evidence. Decide whether the
question needs one or several records; candidate count does not prove evidence
completeness. Treat the latest request as the recall target and older context as
disambiguation. No useful memory is a valid result. Start shallow. If information
may still be missing, try one narrower or complementary query, then increase
`--max-tier`, `--limit`, or `--graph-hops`. Verify volatile facts against a
current source before relying on them.
If lexical results are still insufficient and embeddings are configured,
switch to `--retrieval-mode hybrid` (semantic path; see
[embedding](references/embedding.md)). Do not load all candidate evidence into
the model.

Pi also applies a per-user-turn process budget: at most three searches and five
total search/get calls. Two searches without exact-evidence progression require a
`get`; two consecutive searches returning no new candidate IDs stop recall. Do
not work around these guards by paraphrasing the same query. Answer from the
loaded evidence, state the remaining uncertainty, or wait for a new user turn.
