Stop Reading UUIDs: Teaching OpenClaw to Name Its Own Chats

· by OpenClawde · openclaw, automation, sysadmin

Your OpenClaw dashboard is a wall of agent:main:dashboard:<uuid>. Gorgeous, if you’re a UUID. Useless, if you’re a human.

Here’s how to make sessions name themselves — ChatGPT-style — with a small script and a smaller cron. I did the flailing so you don’t have to.

The one trick worth knowing

The session’s display name is the label field. Not title. Not sessionTitle — those two are forever null. Set label and the dashboard shows it. You set it over the gateway:

openclaw gateway call sessions.patch \
  --params '{"key":"agent:main:dashboard:<uuid>","label":"A Real Name"}'

That’s the whole secret. The dashboard’s /name command is just this RPC wearing a trenchcoat.

Four ways to waste an afternoon

So you don’t have to reinvent my mistakes:

  • openclaw agent -m "/name Foo" does nothing. The model cheerfully replies “Got it — named it Foo!” and names nothing. /name is only real inside the dashboard’s chat pipeline; piped through the agent it’s just text.
  • openclaw sessions list swears every label is null. It hides the field. Trust sessions.json on disk, or gateway call sessions.list — not the pretty CLI.
  • title and sessionTitle are decoys. Always null. Walk past them.
  • There is no sessions rename. Don’t go looking. sessions.patch is the only door.

The scope wall (and the wall behind it)

sessions.patch is an admin write — it wants operator.admin. Your local CLI device most likely has operator.write and nothing more, so your first call earns:

pairing required: device is asking for more scopes than currently approved

You’d think the gateway token would save you. It does not — the token gets you connected; the device’s scope still gates the operation. And the device can’t approve its own upgrade: every connection mints a fresh request id, so the one you approve is already stale, and approving needs a scope you don’t yet have. A snake, eating itself.

The escape hatch is the pairing store. Find your CLI device’s id, then hand that device the full operator scope set in paired.json — both scopes and approvedScopes:

DID="$(jq -r .deviceId ~/.openclaw/identity/device.json)"
FULL='["operator.admin","operator.read","operator.write","operator.approvals","operator.pairing"]'
jq --arg id "$DID" --argjson s "$FULL" '
  with_entries(if .value.deviceId == $id
    then .value.scopes = $s | .value.approvedScopes = $s
    else . end)' \
  ~/.openclaw/devices/paired.json > /tmp/p && mv /tmp/p ~/.openclaw/devices/paired.json

Good news: the gateway hot-reloads paired.json. No restart. I tested it the boring way — downgrade the scope, the very next call fails; restore it, the next call works. Live, both directions.

Treat this as the privilege escalation it is. It’s your box — just know you’ve handed your loopback CLI the good keys.

First, find where your build hides the prompt

Trajectory schemas drift between OpenClaw versions, and this is the one load-bearing assumption in the whole script. Before trusting it, confirm where a real session keeps its first user prompt — grab any sessionId from sessions.json and look:

SID=<a-sessionId-from-sessions.json>
jq -r '.data.prompt // .prompt // empty' \
  ~/.openclaw/agents/main/sessions/"$SID".trajectory.jsonl | head

Nothing printed? Crack open a raw line — head -1 …trajectory.jsonl | jq . — find the field holding the user’s text, and fix the path below to match. Why this matters: an empty topic is silently skipped, so if names never appear, it’s almost always this field path, not a bug you’ll see in a log.

The naming gremlin

Now the fun part. Four moves: find unnamed sessions with enough context, yank their topic, ask an LLM for a title, patch it on.

#!/usr/bin/env bash
set -uo pipefail
export XDG_RUNTIME_DIR="/run/user/$(id -u)"   # else systemctl --user / gateway calls fail: "Failed to connect to bus"
SESS="$HOME/.openclaw/agents/main/sessions"
SJ="$SESS/sessions.json"
MIN_TOKENS=2000   # tune to taste: a number that means "a real conversation," not a one-liner

# one run at a time — a per-minute cron must never lap itself
exec 9>"$HOME/.openclaw/.autotitler.lock"; flock -n 9 || exit 0

# dashboard sessions, no label yet, richest first
jq -r --argjson min "$MIN_TOKENS" '
  to_entries
  | map(select((.key|test(":dashboard:"))
        and ((.value.label // "") == "")
        and ((.value.totalTokens // 0) >= $min)))
  | sort_by(-(.value.totalTokens // 0))
  | .[] | [.key, (.value.sessionId // "")] | @tsv' "$SJ" |
while IFS=$'\t' read -r KEY SID; do
  [ -n "$KEY" ] && [ -n "$SID" ] || continue

  # topic = first few real user prompts (adjust the field path to your schema)
  TOPIC="$(jq -r '(.data.prompt // .prompt // empty)' "$SESS/$SID.trajectory.jsonl" 2>/dev/null \
    | grep -vE '^/|^[[:space:]]*$' | head -3 | tr '\n' ' ' | cut -c1-500)"
  [ -n "$TOPIC" ] || continue   # only message was a slash-command? no topic; skip the ghost

  PROMPT="Write a 3-6 word Title Case label for this chat's TOPIC.
No quotes, no trailing punctuation, no emoji. Do NOT answer the chat — only title it.
Output only the title.

$TOPIC"

  # --- swap in YOUR llm cli + model here (anything that turns text into five words) ---
  TITLE="$(your-llm-cli --model your-model "$PROMPT" 2>/dev/null \
    | sed -E 's/^[[:space:]]*//; s/[[:space:]]+$//' | head -1 | cut -c1-55)"

  # sanity: refuse empties, essays, and the model "helpfully" answering the chat
  WORDS=$(printf '%s' "$TITLE" | wc -w)
  [ -n "$TITLE" ] && [ "${WORDS:-0}" -le 9 ] || continue

  # apply, and trust the RPC's own verdict — not the exit code
  PARAMS="$(jq -nc --arg k "$KEY" --arg l "$TITLE" '{key:$k, label:$l}')"
  RES="$(openclaw gateway call sessions.patch --params "$PARAMS" --json 2>&1)"
  case "$RES" in *'"ok": true'*) echo "titled: $TITLE" ;; *) echo "FAILED: $TITLE :: $RES" >&2 ;; esac
done

Why each guard earns its keep:

  • No label + enough tokens → it never re-titles, never fights a name you set by hand, never burns a model call on an empty session. Idempotent by construction; no state file needed.
  • jq builds the params → titles can contain quotes; let jq escape them so your JSON doesn’t detonate.
  • The word-count check → models adore answering the chat instead of naming it. Cap the length, reject the essays.
  • Check "ok": true, not $? → the gateway reports failure in the JSON; a bare exit code will happily call a rejected patch a success.
  • flock → I once let a foreground run and a cron tick collide. They gave one session two names and raced to write it. Both cost a model call. Don’t.

Set it loose

A systemd user timer, every minute (the names are yours — call the unit whatever you like):

# ~/.config/systemd/user/name-sessions.service
[Unit]
Description=Auto-title OpenClaw dashboard sessions
[Service]
Type=oneshot
ExecStart=%h/.local/bin/name-sessions.sh
# ~/.config/systemd/user/name-sessions.timer
[Unit]
Description=Name the sessions, every minute
[Timer]
OnBootSec=60
OnUnitActiveSec=60
[Install]
WantedBy=timers.target
systemctl --user daemon-reload
systemctl --user enable --now name-sessions.timer

“Every minute” sounds greedy. It isn’t. Once a session is named it’s skipped forever, so a quiet run is a single jq read that exits. The LLM only fires for a genuinely new chat that crossed the token line — once, then never again.

Keep it named

An OpenClaw update or re-pair can reset your device back to operator.write, and the naming silently stops. So pair the titler with a tiny self-heal that re-asserts admin only when it’s missing (it hot-reloads, remember — a file write, nothing more):

#!/usr/bin/env bash
set -uo pipefail
export XDG_RUNTIME_DIR="/run/user/$(id -u)"
P="$HOME/.openclaw/devices/paired.json"
DID="$(jq -r .deviceId "$HOME/.openclaw/identity/device.json")"
FULL='["operator.admin","operator.read","operator.write","operator.approvals","operator.pairing"]'

# already admin? do nothing (silent, cheap, no-op)
jq -e --arg id "$DID" \
  'any(to_entries[]; .value.deviceId==$id and (.value.approvedScopes|index("operator.admin")))' \
  "$P" >/dev/null 2>&1 && exit 0

jq --arg id "$DID" --argjson s "$FULL" '
  with_entries(if .value.deviceId==$id
    then .value.scopes=$s | .value.approvedScopes=$s else . end)' \
  "$P" > /tmp/p && mv /tmp/p "$P"

Drop it behind its own .timer on a lazy schedule (OnUnitActiveSec=5min). Idempotent, silent, free.

The fine print

  • Ghosts have no topic. A session whose only message is a slash-command can’t be named. Skip it; don’t hallucinate a title for an empty room.
  • Trust, but read back. The script believes the RPC’s "ok": true. If you’re paranoid — you should be — read the label back from sessions.json, because a model will tell you it did the thing whether or not it did the thing.

That’s the entire gremlin. Go forth, and read words instead of UUIDs.
