Obsidian Daily Driver

Your daily note is the hub. Tasks you worked on, things you learned, links to what you created — it all flows through the daily note. But Claude Code sessions are stateless. You do an hour of work, close the terminal, and none of it shows up in today's note. This skill bridges that gap — every session can log to your daily note, so when you open Obsidian tomorrow, you see what happened.

When To Activate

- User says "add to daily", "log this", "daily note", "today's note" - User says "what did I do today" (read daily note) - End of a work session when daily notes exist in the vault - After completing significant work that should be logged - User says "task" or "todo" in the context of daily notes - Session produces artifacts worth tracking (new files, discoveries, decisions)

Do NOT trigger for:

• Vaults without daily notes
• When user explicitly doesn't want daily logging
• Trivial interactions (single questions, typo fixes)

Instructions

Step 1: Find Today's Daily Note

Daily notes follow a date-based naming convention:

TODAY=$(date +%Y-%m-%d)

# Check common locations
DAILY="$VAULT_PATH/Daily/$TODAY.md"
[ -f "$DAILY" ] || DAILY="$VAULT_PATH/Journal/$TODAY.md"
[ -f "$DAILY" ] || DAILY="$VAULT_PATH/daily/$TODAY.md"

# Or use CLI
obsidian daily:read 2>/dev/null
obsidian-cli daily 2>/dev/null

# Check CLAUDE.md for daily note path convention
grep -i "daily" "$VAULT_PATH/CLAUDE.md" 2>/dev/null

If today's note doesn't exist, create it from the daily template:

# Find the daily template
TEMPLATE=$(find "$VAULT_PATH/Templates" -iname "*daily*" | head -1)

Create with proper frontmatter:

---
type: daily
date: YYYY-MM-DD
tags:
  - daily
---

# YYYY-MM-DD

## Tasks

- [ ]

## Log


## Links

</find_daily>

Step 2: Read Existing Content

Before appending, read what's already there:

cat "$DAILY"

Understand the structure so you append to the RIGHT section:

• Tasks go under ## Tasks
• Logs go under ## Log
• Links go under ## Links

Don't duplicate entries that already exist.
</read_daily>

Step 3: Append Content

Based on what you're logging, append to the correct section.

Adding a task:

# Using CLI
obsidian daily:append content="- [ ] Task description"

# Direct file: find ## Tasks section and append after it

Append under ## Tasks:

- [ ] Task description

Logging work done:

Append under ## Log:

- Worked on [[project-name]]: brief description of what was done
- Fixed: [[bug-or-issue]] — what was wrong and how it was fixed
- Created: [[new-note]] — why it was created

Adding links to created artifacts:

Append under ## Links:

- [[note-created-today]] — context for why
- [[meeting-note]] — key takeaways

Session summary (end of session):

Append under ## Log:

### Claude Session — HH:MM

**Worked on:** brief description
**Created:**
- [[note-1]]
- [[note-2]]
**Decisions:**
- Decision made and why
**Next:**
- [ ] Follow-up task

Step 4: Handle CLI vs Direct Write

**Official CLI (preferred — respects plugins/templates):** ```bash obsidian daily:append content="- [ ] New task" obsidian daily:append content="- Completed: task description" ```

Yakitrak CLI:

obsidian-cli create "$TODAY" --append --content "- [ ] New task"

Direct file append:

# Careful: append to the right SECTION, not just end of file
# Read the file, find the section, insert content, write back

When using direct file write, you MUST:

1. Read the file first
2. Find the target section (## Tasks, ## Log, etc.)
3. Insert content after the section heading (or after existing items)
4. Write the whole file back

Do NOT just append to the end of the file — it breaks the structure.
</write_method>

Step 5: Cross-Link

If today's work relates to project notes, meeting notes, or other daily notes:

• Link from daily to the related note: [[related-note]]
• Also add a backlink FROM the related note TO today's daily note
  (only if the related note doesn't already link back)

# In today's daily note:
- Continued work on [[project-x-api-design]]

# In project-x-api-design.md, add:
## Activity
- [[2026-02-12]] — added rate limiting approach

This creates bidirectional links that show up in Obsidian's backlinks panel
and graph view.

Log Entry Formats

Keep entries concise. The daily note is a log, not a journal.

Task added:

- [ ] Brief task description

Task completed:

- [x] Completed task description

Work log:

- Worked on [[note]]: one sentence of what was done

Decision made:

- Decided: decision summary (see [[decision-note]] for detail)

Discovery:

- Found: discovery summary — [[related-note]]

Session summary:

### Claude Session — HH:MM
**Worked on:** [topic]
**Outcome:** [result]
**Next:** [what's left]

Output Format

When appending:

Added to daily note (YYYY-MM-DD):
- [what was added and to which section]

When creating daily note:

Created daily note: [[YYYY-MM-DD]]
Path: Daily/YYYY-MM-DD.md
Added: [initial content]

When reading:

Today's note (YYYY-MM-DD):
- Tasks: X open, Y completed
- Log: [summary of entries]

NEVER

• Overwrite the daily note (append only)
• Append to the end of the file without finding the right section
• Duplicate entries that already exist
• Create verbose log entries (keep them to one line)
• Skip reading the existing note before appending
• Log trivial interactions (single questions, typo fixes)

ALWAYS

• Read the daily note before appending to it
• Append to the correct section (Tasks/Log/Links)
• Use wikilinks when referencing other notes
• Create the daily note from template if it doesn't exist
• Include timestamps on session summaries
• Check for the daily note path in CLAUDE.md first

Example

End of session where user built a new API endpoint:

Session ending. Logging to today's daily note...

Reading Daily/2026-02-12.md...

Appended to ## Log:
- Worked on [[project-api]]: built rate limiting endpoint, added tests
- Created: [[api-rate-limiting]] — design doc for rate limit approach

Appended to ## Tasks:
- [ ] Deploy rate limiting to staging
- [x] Write rate limiting tests

Appended to ## Links:
- [[api-rate-limiting]]

Daily note updated.

User says "add a task to my daily":

Reading Daily/2026-02-12.md...

What task should I add?

Daily note updated.

What DOESN'T work: - Appending to end of file — breaks note structure, content ends up after footer - Using echo >> for append — doesn't respect sections, can corrupt YAML - Creating daily note without checking template — inconsistent format - Not reading existing content — duplicates tasks or logs
