description: Save to ECHO memory — route content to its canonical home (search-first, idempotent)
argument-hint: "[what to remember]"
---

Use the **echo-memory** skill to persist this to the ECHO vault:

> $ARGUMENTS

Prefer the one-call **`capture`** — it routes (via the entity index), derives the canonical path, stamps complete frontmatter (kind-default `status`, the kind seeded into `tags`), indexes, auto-links mentioned entities, and writes the Agent-Log line. Pick the `--kind` from the content (`person, company, concept, reference, meeting, project, area, semantic, episodic, working, skill, decision`); add `--tags` when obvious; use `--inbox` only when the home is genuinely unknown. Write multi-line bodies to a file with the Write tool (cross-platform, no heredoc) — updates to an existing entity preserve the whole body, so don't pre-trim it.

```bash
ECHO="${CLAUDE_PLUGIN_ROOT}/skills/echo-memory/scripts/echo.py"   # run with: python3 "$ECHO" ... (Windows: python / py -3)
[ -f "$ECHO" ] || ECHO=$(ls /sessions/*/mnt/.remote-plugins/*/skills/echo-memory/scripts/echo.py 2>/dev/null | head -1)   # CoWork sandbox fallback
python3 "$ECHO" capture "<title>" <bodyfile> --kind <kind> [--aliases a,b] [--tags t1,t2] [--source p1,p2]
python3 "$ECHO" capture "<title>" --inbox     # unknown home -> idempotent inbox line
```

**If capture exits `76` (duplicate gate):** the title strongly resembles an existing entity — do NOT retry blindly. Show the operator the printed candidates and either update the existing note (`capture ... --merge-into <slug>`) or, only after they confirm it's genuinely distinct, re-run with `--force`.

Drop to the low-level verbs only for shapes `capture` doesn't model (a project `## Status` replace, an ADR mirror, a daily-note edit):

```bash
python3 "$ECHO" put   <routed/path>.md <bodyfile>                       # create/overwrite (verifies)
python3 "$ECHO" patch <path>.md append heading "<H1::Sub>" <bodyfile>   # targeted append
```

Write in third person about the vault owner; never put `[[wikilinks]]` in frontmatter. `capture` handles `agent_written`, `source_notes`, indexing, and linking for you; if you write by hand, `resolve "<title>"` first to avoid duplicates and `bump` `updated:` only on substantive changes.
