What is claude-blog-brain?

A source-based content workspace for Obsidian, a note-taking app that stores linked files locally. It organizes blog research, drafts, updates, editorial planning, and evidence in a shared vault.

Use it to create client workspaces, import sources, synthesize research, produce reports and visuals, check notes, and track the next task.

It reduces the risk of losing source material or making unsupported claims. It also gives repeatable commands for turning research into content and checking the workspace.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00342	$0.01080
Opus 5	$0.00171	$0.00540
Sonnet 5	$0.00068	$0.00216
Haiku 4.5	$0.00034	$0.00108

Measured 9d ago against content hash 2fd3b999ea11, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

claude-blog-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 9d ago.

The scan reads SKILL.md. This mod also ships 14 executable files (.raw/sources/claude-blog-skill/scripts/ai_citation_score.py, .raw/sources/claude-blog-skill/scripts/analyze_blog.py, .raw/sources/claude-blog-skill/scripts/blog_hygiene.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Changes

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.
