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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00135 | $0.03907 |
| Opus 5 | $0.00068 | $0.01954 |
| Sonnet 5 | $0.00027 | $0.00781 |
| Haiku 4.5 | $0.00014 | $0.00391 |
Grade A, and why
obsidian-brain 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.
How it starts
The opening of the file, as written. The whole thing — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian Brain: the Company Knowledge Layer
Build and maintain a local Obsidian vault that holds everything the business (and the founder behind it) knows, so every other skill reads real context before acting and writes its work back when done.
The framing: Claude is the uranium, raw reasoning power in unlimited supply. The company's knowledge is what that power runs on. The Obsidian vault is the power plant, the infrastructure that turns the two into compounding output. A model without your facts produces generic advice; the same model on a well-built vault produces output that is specific, consistent across sessions, and smarter every week.
Why Obsidian: it stores plain markdown files on the user's own disk. Markdown is what Claude reads and writes natively, local files keep the data private and portable (no export lock-in), and wiki links turn scattered notes into the entity graph of the business. Any folder of markdown works the same way; Obsidian (https://obsidian.md) is simply the best free tool to browse and edit it.
This skill is the foundation of the kit. The other skills do the SEO and GEO work; this one defines where knowledge lives, how it gets in, and how it stays navigable. Four reference files hold the depth, load them when the matching section says so:
references/getting-started.md: the from-zero on-ramp, install Obsidian, connect the agent, run the first scaffold session. Load this first when the user has no vault or no agent set up yet.references/vault-architecture.md: the full layered structure, frontmatter conventions per note type, hub and MOC patterns, naming and macOS pitfalls.references/import-workflows.md: step-by-step import for documents, WhatsApp, email and transcripts, plus the multi-agent fan-out for large backlogs.references/link-audit.md: how to run and read the two bundled scripts that find broken links, orphans, unreachable notes and duplicate people.
If the user is starting from zero (Obsidian not installed, no vault yet, agent not connected), begin with references/getting-started.md: it walks install, connecting the agent to the vault folder, and the first scaffold session in order, then this skill takes over.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

obsidian-brain is a skill published in the GitHub repository Thibaultbm/claude-seo-geo (16 stars, last pushed yesterday), licensed MIT. It adds 135 tokens to every session and 3,907 once invoked, about $0.0007 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.
