Efficient Time Entry with Timewarrior

Fast, consistent time tracking: avoid tag chaos, time guessing, and duplicate entries through a proven 5-step workflow.

When to Use This Skill

• ✅ You need to log work quickly but want consistency by Friday
• ✅ You're backfilling yesterday/last week but can't remember exact times
• ✅ You have gaps in your week and need to fill them with accurate tags
• ✅ You're tired and might create duplicate tag names

When NOT to Use This Skill

• ❌ You're doing real-time tracking (just timew start as you work)
• ❌ You need detailed historical reconciliation (use full reference docs)
• ❌ You're analyzing trends (use analysis reports)

The Core Problem

Without discipline, agents under time pressure:

1. Skip tag discovery → dev, development, DEV all in use by Friday
2. Invent times → backfilled data doesn't match actual patterns
3. Create placeholder tags → buffer, misc, admin pollute the list
4. Guess-and-fix later → tag mismatches discovered hours later
5. Leave unmeasured gaps → incomplete daily totals

The 5-Step Efficient Entry Workflow

Step 1: Query Existing Tags BEFORE Entering New Data

Copytimew tags :week

Why: Takes 5 seconds. Prevents tag name chaos. You'll see exactly what tags you've been using.

What you do: Note the exact spelling, case, and format (e.g., development not dev).

Step 2: For Rapid Same-Day Entry, Copy Tags from Recent Work

Scenario: You have 5 minutes before a meeting. Log 3 activities today.

Copy# Find exact tag names from similar recent work
timew export :day | grep -o '"tags":\[[^]]*\]' | head -5

# Then use those EXACT names when entering new entries
timew start 9am development project-alpha
timew stop
timew start 11am code-review team-beta

Key: You're reusing proven tag names, not inventing new ones.

Step 3: For Backfill (Yesterday/Last Week), Query the Pattern Day

Scenario: You forgot to log yesterday. You need times AND tags.

Copy# Check a similar day from this week for both times and tags
timew report 2025-01-18 rc.columns=start,end,tags

# Then match that pattern for yesterday
timew track 2025-01-19T09:00:00 - 2025-01-19T12:00:00 development project-alpha
timew track 2025-01-19T13:00:00 - 2025-01-19T17:00:00 development project-alpha

Key: You're matching existing patterns, not guessing new times. If you can't remember exact times, use the anchors you DO remember (meeting times, when you left).

Step 4: Fill Gaps ONLY with Existing Tags (No Placeholders)

Scenario: Your week has gaps between logged sessions.

Copy# Check which tags dominated the day
timew summary :day monday

# Fill gaps > 30 min using tags from that day only
timew track 12:00 - 14:00 development    # Gap after morning dev
timew track 11:00 - 13:00 project-alpha  # Gap with context from work

# Skip gaps < 30 min (context-switching overhead not worth tracking)

Key: Never create buffer, context-switch, or admin tags. Reuse what you know.

Step 5: Bulk Verify Before Friday EOD

Copy# See all tags you've used this week
timew tags :week

# Look for duplicates, typos, variations
# (e.g., "dev" vs "development", "alpha" vs "project-alpha")

# Check for placeholder tags you forgot about
timew summary :week

Fix discovered duplicates:

Copy# Find all entries with misspelled tag
timew export :week | grep -o '"dev"'

# Modify entries to use correct tag
timew tag @5 development
timew untag @5 dev

Quick Reference: The Workflow Matrix

Common Mistakes (And How the Workflow Prevents Them)

When Each Step Takes Under 1 Minute

• Step 1 (Query tags): 5 seconds → timew tags :week
• Step 2 (Copy tags): 10 seconds → timew export :day | grep tags
• Step 3 (Query pattern): 10 seconds → timew report SIMILAR_DAY
• Step 4 (Fill gaps): 30 seconds → 3-4 timew track commands
• Step 5 (Verify): 20 seconds → timew tags :week and scan for typos

Total for a complete backfill + gap fill: ~2 minutes instead of 10+ minutes of guessing and fixing.
