brief

If the Mori server is unreachable (a tool call returns a connection error, ECONNREFUSED, or timeout), do not show a stack trace. Tell the user the Mori server appears to be down and that a running Mori server is required. Point them to the quickstart at https://github.com/fjwood69/mori#quickstart and suggest checking the server URL in plugin settings. Then stop.

Argument Parsing

Parse the raw input for:

• --project <name>: scope the brief to a specific project
• --auto: detect project from the current git working directory
• --post-compact: lightweight delta re-grounding after a context compaction — surfaces only what changed in shared state since the last brief, not the full base. Triggered automatically by the Mori SessionStart hook when source == "compact" — Claude Code re-fires SessionStart after compaction with that source field, which is the only supported mechanism for injecting context at that seam. Can also be run manually.

If no arguments: run the standard unscoped brief.

Marker file

The brief boundary is tracked in a per-config-dir marker:

${CLAUDE_CONFIG_DIR:-$HOME/.claude}/.mori-last-brief

It holds the UTC ISO-8601 timestamp of the most recent brief. Stamp it (overwrite with the current UTC time) at the end of every brief run, in all modes:

date -u +%Y-%m-%dT%H:%M:%SZ > "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/.mori-last-brief"

Execution

1. Resolve project (if --auto or --project)

If --auto:

1. Check for .mori-project file — walk up from CWD to filesystem root; if found, use its text content (stripped, lowercased)
2. Else check MORI_PROJECT environment variable
3. Else run git rev-parse --show-toplevel 2>/dev/null and use basename of the result (lowercased)
4. If no project detected: fall back to unscoped brief and note "no project detected, loading unscoped"

If --project <name>: use that name directly.

2. Call the MCP tool

Standard brief (default):

• With project: call mori-brief with project=<name>
• Without project: call mori-brief (no params — loads all memories up to cap)

Post-compact brief (--post-compact): resolve the since boundary first (session-aware), then call the delta tool.

1. Read the marker ${CLAUDE_CONFIG_DIR:-$HOME/.claude}/.mori-last-brief. If it exists and is non-empty, use its contents as since.
2. Else derive session start (best-effort): the start time of the current session transcript .jsonl (e.g. the file's first-event timestamp, or its creation time).
3. Else omit since and let the server default window (MORI_POST_COMPACT_WINDOW, default 6h) apply.

Then call mori-brief with post_compact=true, plus project=<name> if resolved and since=<resolved> if found:

mori-brief(post_compact=true, project="<name>", since="<iso-or-omitted>")

The delta lists are capped; if the tool reports "…N more — run a full /brief if you need the rest", relay that pointer rather than auto-running a full brief.

3. Check pending messages

Call mori-msg_recv(unacked=True) (both modes — new messages are part of the delta).

If messages are returned, surface them after the memory summary:

• task / question — prominent; include a ready-made reply command:
  • task → mori-msg_send(to="<from_host>", type="ack", reply_to="<id>", body="acknowledged")
  • question → mori-msg_send(to="<from_host>", type="reply", reply_to="<id>", body="...")
• decision / broadcast — awareness items only (lower prominence)

Skip this section silently if no pending messages or if mori-msg_recv fails (daemon may not be running).

On --post-compact, also catch cross-device traffic that arrived during the session: call mori-nats_sub(replay=true, wait=2) and surface anything new.

4. Stamp the marker

Write the current UTC time to the marker file (see Marker file above). Do this in both modes, after the tool calls.

5. Report

Standard brief: report "Ready" — summarise what was loaded (memory counts, project scope, dream state, pending message count if any). Do not take autonomous actions.

Post-compact brief: report a one-line abbreviated re-grounding summary, e.g. "Re-grounded — N changed, M superseded, K messages". Do not re-dump the full base; the working context is already preserved by the compaction summary.
