Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02653 | $0.02653 |
| Opus 5 | $0.01326 | $0.01326 |
| Sonnet 5 | $0.00531 | $0.00531 |
| Haiku 4.5 | $0.00265 | $0.00265 |
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.
How it starts
The opening of the file, as written. The whole thing — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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'sSKILL.mdon 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
descriptionfield (~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.mdat 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
.canvasfiles with nodes, edges, and visual layouts. - obsidian-bases: Create
.basefiles 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.mdwith bidirectional sync. - daily-rituals: Structured daily and weekly planning cycle. Enhances
/open-dayand/close-daywith daily notes inplan/. 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.

awesome-second-brain CLAUDE.md is an instructions file published in the GitHub repository superuser-pal/awesome-second-brain (14 stars, last pushed 4mo ago), licensed MIT. It adds 2,653 tokens to every session, about $0.0133 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
