wdid — what did I do?

A small CLI that reports your Claude Code activity for a given day, derived from the JSONL session logs under ~/.claude/projects/.

Usage

./wdid                  # today
./wdid yesterday
./wdid 2026-04-30
./wdid --no-summarize   # skip Haiku-based descriptions

Output:

START  END    DUR    PROJECT  DESC
-----------------------------------------------------------------------------------
09:12  10:04  00:48  api      Add rate limiting middleware and integration tests
10:20  11:35  01:11  webapp   Migrate user settings page to new component library
13:30  14:02  00:31  scripts  Investigate slow nightly backup job
-----------------------------------------------------------------------------------
       total  02:30  (3 sessions)

How it figures out engagement

A single Claude Code session log can span many real working sessions (claude --resume reattaches to old logs hours or days later). wdid walks each log, sorts events by timestamp, and splits into engagement sessions wherever the gap between consecutive events exceeds 30 minutes.

Engagement time per session is the sum of consecutive in-session gaps (naturally capped at 30 min by the splitting rule), plus a 3-minute trailing read buffer when the session ends on an assistant message — the logs have no close/exit signal, so we credit roughly the same idle window that triggers Claude's own away_summary.

Subagent logs (.../subagents/...) are skipped — they overlap with their parent session and would double-count time.

Session descriptions

The DESC column comes from, in order of preference:

1. A Haiku-generated summary (cached at ~/.cache/wdid/titles-YYYY-MM-DD.json). The summary is built from your prompts, the tool actions Claude took (file edits, shell commands), and the last few assistant replies, so it tends to reflect what was actually done rather than just the opening prompt.
2. Claude's own ai-title entry, if Haiku is disabled or fails.
3. The first non-slash user prompt.

Requirements

• Python 3.9+ (standard library only)
• Optional: ANTHROPIC_API_KEY environment variable for Haiku-based summaries. Without it, wdid falls back to ai-title / first prompt.

The summarizer uses claude-haiku-4-5-20251001 via the Anthropic Messages API, called directly through urllib. Each title is cached, so subsequent runs make zero API calls.
