Log Session to Tana

Write a session log to Tana for the current session. Requires a Tana MCP server with import-paste and calendar-node tools. In Claude Code these are mcp__tana-outliner-local__import_tana_paste and mcp__tana-outliner-local__get_or_create_calendar_node; in other agents use the equivalents.

Tana workspace ID: GbpulTT1pv Session tag ID: qB78NPBiRNBM (the tag is applied by ID, so renaming it in Tana won't break this skill)

Step 1: Gather context

1. Project name: from the working directory, git remote, or package.json. If you can't tell, ask the user.
2. Summary: 1-2 sentences on what was accomplished. If $ARGUMENTS is given, use it as extra context.
3. Key changes: git diff --stat and git log --oneline -5 (skip if not a git repo).
4. Status: Completed, In progress, Paused, or Failed, based on context.
5. End time: now, local: date +"%Y-%m-%dT%H:%M:%S"
6. Start time and token usage: run python3 scripts/session-stats.py (path relative to this skill's directory). It prints Start:, Output:, New input:, and Cache reads: lines for the most recent Claude Code transcript of the current directory.
   • If this session was already logged to Tana, log only the work since then: pass --since <previous entry's End time> and use that as the Start time.
   • To backfill a past entry, pass --since and --until with its Start and End times.
   • If the script exits non-zero (not Claude Code, no transcript), omit the Token usage block and take the start time from the user or your best estimate of the session start.
