awesome-second-brain CLAUDE.md

awesome-second-brain CLAUDE.md is an instructions file for coding agents from superuser-pal/awesome-second-brain. It costs 2,653 tokens per session, scanned A, original, MIT.

Repository instructions for an Obsidian-based personal knowledge system, where notes, decisions, and work information are organized as a linked vault. Obsidian is a note-taking app that stores connected Markdown files.

In plain words
What is it for?
Use them when adding or editing notes, recording something to remember, reorganizing knowledge, or finding links between related notes in the vault.
Why use it?
They help an agent preserve the vault's structure and avoid losing information, including keeping note metadata, respecting configuration files, and recording memories in the intended topics.

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

awesome-second-brain CLAUDE.md 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 5d 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.

Awesome Second Brain

Awesome Second Brain vault — Obsidian-based personal knowledge system for work notes, decisions, performance tracking, and Claude context.

Rules

  • Never modify .obsidian/ config files unless explicitly asked.
  • Preserve existing frontmatter when editing notes.
  • Git sync is handled by the user's preferred method (obsidian-git, manual commits, etc.) -- don't configure git hooks or auto-commit.
  • When asked to "remember" something, write to the relevant brain/ topic note with a link to context. Never create memory files in ~/.claude/ -- they are not version-controlled.
  • Prefer Obsidian CLI over filesystem when Obsidian is running.
  • Skills are in .claude/skills/. Load a skill's SKILL.md on demand when the relevant operation is needed — do not preload all skills.
  • Always check for and suggest connections between notes.
  • Every note must have a description field (~150 chars). Claude fills this automatically.
  • Zero data loss: when reorganizing, always use git mv (or your file manager if not using git). Never delete without explicit user confirmation.
  • North Star: Read brain/NORTH_STAR.md at session start. Reference it when suggesting priorities or trade-offs. Update it when the user signals a shift in goals.

Skills & Capabilities

This vault has obsidian-skills installed in .claude/skills/. Follow these skill conventions:

  • obsidian-markdown: Obsidian-flavored markdown -- wikilinks, embeds, callouts, properties. Always prefer [[wikilinks]] over markdown links.
  • obsidian-cli: CLI commands for vault operations when Obsidian is running.
  • json-canvas: Create .canvas files with nodes, edges, and visual layouts.
  • obsidian-bases: Create .base files with views, filters, and formulas. Bases core plugin is enabled.
  • defuddle: Extract clean markdown from web pages via defuddle parse <url> --md.
  • qmd: Semantic search across the vault via QMD. Use PROACTIVELY before reading files -- qmd query "..." for hybrid search, qmd search "..." for keyword, qmd vsearch "..." for semantic. Falls back to grep/glob if QMD not installed.
  • project-management: Create, track, and archive domain-scoped projects. Aggregates tasks from all sources into dashboards/TASKS.md with bidirectional sync.
  • daily-rituals: Structured daily and weekly planning cycle. Enhances /open-day and /close-day with daily notes in plan/. Adds /week-prep, /week-close (with synthesis), and /week-cycle.
  • create-agent: Create and validate Domain Agents — interactive, domain-bound agents for focused context work.
  • prompts: Search, promote, and demote atomic prompt pages. Dormant prompts live in docs/prompts/; promoted ones get a /prompts:<slug> command.
  • strategy: Search, promote, and demote reasoning strategy pages. Dormant strategies live in docs/strategies/; promoted ones get a /thinking:<slug> command.

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.
