About the project

obsidian-second-brain turns an Obsidian vault into persistent, searchable memory for Claude Code and other command-line coding agents, storing knowledge as linked Markdown notes. It is for developers, founders, writers, and researchers who want agents to retain project context across sessions. Its catalogue entries provide commands, hooks, a plugin, a skill, and instructions for capturing, finding, and maintaining that memory.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

obsidian-daily scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Use the obsidian-second-brain skill. Execute /obsidian-daily:

  1. Read _CLAUDE.md first if it exists in the vault root

  2. If CRITICAL_FACTS.md exists in the vault root, read it for timezone; otherwise use the system timezone

  3. Check if today's YYYY-MM-DD.md exists in the daily folder, resolved per references/folder-map.md (wiki-style wiki/daily/, Obsidian-style Daily/)

    • If not: read the daily-note template (Templates/Daily Note.md, or lowercase templates/ if that is the vault's folder), fill in date fields, create the file
    • If yes: update existing note (inject, don't overwrite)
  4. Pull calendar events (if a Google Calendar MCP is connected):

    • Find the primary calendar with mcp__claude_ai_Google_Calendar__list_calendars, then fetch today's events with mcp__claude_ai_Google_Calendar__list_events (these are the tool names exposed by the claude.ai Google Calendar connector; if your calendar MCP namespaces its tools differently, use that server's list_events equivalent)
    • Add a ## Calendar section to the daily note with:
      • Time, title, attendees for each event
      • For meetings with known entities: link to their [[Person Name]] pages
    • If no calendar MCP is connected, skip silently (don't error)
  5. Pull overdue and due-today tasks from kanban boards:

    • Scan the boards folder (resolved per references/folder-map.md) for items with @{date} that match today or are past due
    • Add to the daily note's Focus section with priority markers
  6. Scan the current conversation for anything relevant to today:

    • Tasks in progress, people mentioned, decisions made, what's being worked on
    • Pre-fill or update the note's sections with that context
  7. Check the operation log for last night's sleeptime consolidation (if Logs/ exists: read yesterday's Logs/YYYY-MM-DD.md; otherwise read log.md):

    • If the nightly agent ran, summarize what it did (reconciled, synthesized, healed)
    • Add a brief "Overnight changes" note so the user knows what happened while they slept
  8. Return the path of the daily note when done.


AI-first rule: Every note created or updated by this command MUST follow references/ai-first-rules.md - ## For future agent preamble, rich frontmatter (type, date, tags, ai-first: true, plus type-specific fields), recency markers per external claim, mandatory [[wikilinks]] for every person/project/concept referenced, sources preserved verbatim with URLs inline, and confidence levels where applicable. If that path does not resolve from your working directory, search upward for it; if you still cannot read it, say so before writing rather than producing a note that silently skips the rule. The vault is for future agent retrieval - not human reading.

Anti-fabrication: Search exhaustively before claiming any note, person, or file is absent - false absence is the most common failure mode - and never invent facts, entities, or dates (mark unknowns as TBD). See the anti-fabrication and search-completeness hard rules in references/ai-first-rules.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
