Nightly Travel Sync

Process steps in order. Do not skip ahead.

Run this bundle silently. Each step surfaces its own results via mcp__nanoclaw__send_message; the bundle itself adds no chat surface. The fire-time precheck (precheck.py) gates wake-ups on travel-db.json freshness — see precheck.py for the cadence predicate and threshold.

A step that hits a technical failure surfaces a one-line note and finishes the run. There is no mid-run continuation. Recovery is the next daily cron fire.

Step 1 — TripIt → Reclaim sync

Run the sync in-container; credentials are swapped at the OneCLI gateway (#748):

bash /home/node/.claude/skills/tessl__nightly-travel-sync/scripts/sync-tripit.sh

The script runs reclaim-tripit-timezones-sync (agent-image global) and prints one JSON object: { noChanges, homeTimezone, timezoneChanges[], segments[], ooo, conflicts[], errors[] }. Parse it:

• errors non-empty — surface the messages via mcp__nanoclaw__send_message, emit <internal>nightly-travel-sync exited step-1: sync-error</internal> as your final turn text, and finish. (A missing-credential or gateway-auth failure lands here.)

• Persist the timezone segments to the host — always call this on a clean run so the owner-tz backbone (scheduler local-tz, the 30-min heartbeat advisory) stays current:

  mcp__nanoclaw__persist_tz_segments({ segments: <the parsed `segments` array> })
  

  Call it even when segments is [] — an empty array is the correct "no active travel" state and clears stale segments.

• Report changes via mcp__nanoclaw__send_message when any are non-empty: timezoneChanges (new/updated zones), ooo (OOO blocks applied), conflicts (overlapping trips — flag as a warning). Silent when the run is clean with nothing to report.

If the script itself exits non-zero (the CLI/package missing, or ONECLI_URL unset / the gateway unreachable so the sync could not run), surface its stderr via mcp__nanoclaw__send_message, emit <internal>nightly-travel-sync exited step-1: sync-fail</internal>, and finish. Otherwise proceed to Step 2.

Step 2 — Refresh travel-schedule.json from TripIt ICS

python3 /home/node/.claude/skills/tessl__nightly-travel-sync/scripts/refresh-travel-schedule.py

Pulls live ICS from /workspace/group/tripit-url.txt, writes /workspace/group/travel-schedule.json (record shape + reader contract in state-schema.md). On non-zero exit (TripIt feed unreachable after retries, malformed ICS, missing/empty tripit-url.txt), surface a one-line note via mcp__nanoclaw__send_message carrying the script's stderr — do not swallow the failure — then proceed to Step 3. The file's mtime stays unchanged on failure, so Step 3's probe still re-checks staleness independently. On success, proceed to Step 3.

Step 3 — Travel-schedule freshness probe with Gmail fallback

Do NOT alert on travel-schedule.json mtime alone. The escalation signal is a stale status and a matching TripIt forwarded-confirmation email from the Gmail check below, never mtime by itself.

python3 /home/node/.claude/skills/tessl__nightly-travel-sync/scripts/check-travel-freshness.py

Parse the JSON output and branch on status (the staleness threshold lives in scripts/check-travel-freshness.py):

• "missing" — file does not exist. Report via mcp__nanoclaw__send_message.
• "fresh" — silent. Skip to Step 4.
• "stale" — consult Gmail. Script output includes gmail_query (already buffered for the after: boundary), subject_prefix, and mtime. Pass gmail_query verbatim to the fetch script and pipe it into the filter — one command, no tool call:

set -o pipefail
python3 /home/node/.claude/skills/tessl__nightly-travel-sync/scripts/fetch-tripit-emails.py '<gmail_query>' \
  | python3 /home/node/.claude/skills/tessl__nightly-travel-sync/scripts/filter-tripit-bookings.py

set -o pipefail is required, not decoration: without it the filter's exit 0 masks the fetch's exit code and the truncation signal below is lost.

Do NOT fetch the mail yourself. The fetch script sanitizes every message inside the container before printing it, so raw email text never enters this session (/workspace/group/nanoclaw-poison-defense.md); an agent-driven Gmail call would put it there. Read only the filter's output.

Branch on the pipeline's exit code:

• 0 — the whole window was examined, so count is trustworthy. 0 → silent; ≥ 1 → report via mcp__nanoclaw__send_message with the matching subjects, the count, and the travel-schedule mtime.
• 3 — the fetch hit its message cap (its stderr carries WINDOW_TRUNCATED), so older mail in the window was never examined. A count of 0 here does NOT mean "no booking found" — report regardless of count via mcp__nanoclaw__send_message: say the confirmation check could only see the newest N emails since the schedule mtime, that a booking confirmation may be sitting behind the cap, and include any matches it did find. Note it will keep firing until the schedule refreshes, because the window widens with staleness.
• 1 or 2 — stdout is empty; a diagnostic is on stderr. Surface that stderr in a one-line note via mcp__nanoclaw__send_message. Exit 2 is operator-actionable config: the OneCLI gateway is not authenticating the Gmail call, this agent's tier is gated from Google by design, or the co-loaded tessl__heartbeat mount is missing. Exit 1 is a failed Gmail call; the next nightly fire retries.

Never read a non-zero exit as "no bookings found" — silence is correct only on exit 0. Proceed to Step 4 in every case.

Step 4 — Rebuild travel-db.json from the schedule

python3 /home/node/.claude/skills/tessl__check-travel-bookings/scripts/build-travel-db.py

Produces /workspace/group/travel-db.json. The script lives in the sibling check-travel-bookings skill's dir. On non-zero exit, surface a one-line note via mcp__nanoclaw__send_message, emit <internal>nightly-travel-sync exited step-4: build-nonzero</internal> as your final turn text, and finish (Step 5's detection and Step 6 both hard-fail on a missing DB, and the next cron re-runs from Step 1). Otherwise proceed to Step 5.

Step 5 — Log newly-appeared trips to daily memory

Record trips that appeared in travel-db.json since the last run to the group daily log, so the main agent gains durable awareness of them. This step is silent to chat by design (#204) — the owner books the trips himself, so a per-trip mcp__nanoclaw__send_message is noise. The only chat output here is the one-line technical-failure note the run-wide convention already prescribes.

First detect (reads the DB + snapshot, writes nothing):

python3 /home/node/.claude/skills/tessl__nightly-travel-sync/scripts/detect-new-trips.py

Parse the JSON output (detection predicate and snapshot handling live in the script — detect-new-trips.py module docstring):

• seeded is true — first run with no usable prior snapshot. Log nothing (do NOT dump the itinerary), then commit the seed snapshot below and proceed to Step 6.

• new_trips is empty — nothing new. Commit below (a harmless snapshot refresh) and proceed to Step 6.

• new_trips non-empty — for each entry, append its log_line to the group daily log, prefixed with the current time as - HH:MM UTC :

  echo "- HH:MM UTC <log_line>" \
    | python3 /home/node/.claude/skills/tessl__trusted-memory/scripts/append-to-daily-log.py --target group
  

  The helper handles locking, line-dedup, and atomic append — do NOT write the log file directly. If an append exits non-zero, surface a one-line note via mcp__nanoclaw__send_message, skip the commit (leave the snapshot so the next run retries), and proceed to Step 6.

After logging every new trip (or immediately on a seed / empty result), persist the snapshot — this is the sole writer of travel-trips-seen.json, and it must run only after the logging above succeeds:

python3 /home/node/.claude/skills/tessl__nightly-travel-sync/scripts/detect-new-trips.py --commit

On a non-zero exit from either detect-new-trips.py invocation, surface a one-line note via mcp__nanoclaw__send_message and proceed to Step 6 (the next cron re-runs from Step 1). Proceed to Step 6.

Step 6 — Travel bookings check

Skill(skill: "tessl__check-travel-bookings")

Finds missing flights/hotels for upcoming trips. The inner skill reports gaps and is silent when all bookings are complete or snoozed.

Emit exactly one <internal> line so a silent-success watchdog can distinguish healthy quiet from broken-silently runs: <internal>nightly-travel-sync ran <slot_key>: clean</internal> when no step surfaced anything in Steps 1–6, or <internal>nightly-travel-sync ran <slot_key>: surfaced</internal> when at least one did. New-trip logging in Step 5 is not a chat surface — a run that only logged new trips is still clean. <slot_key> is today's UTC date in YYYY-MM-DD form. No user-facing output. Finish here.
