Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00025 | $0.00650 |
| Opus 5 | $0.00013 | $0.00325 |
| Sonnet 5 | $0.00005 | $0.00130 |
| Haiku 4.5 | $0.00003 | $0.00065 |
Grade A, and why
chrome-history 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 13d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chrome History Query Skill
Search and filter your Chrome browsing history using natural language queries.
What It Does
- Parses natural language queries to understand date ranges and filters
- Queries Chrome's SQLite history database
- Filters out noise (social media, email, redirects)
- Groups results by type (reading, research, tools, events)
- Returns formatted markdown with links
Supported Queries
Date Range
- "yesterday" → previous day only
- "today" → today only
- "last week" → past 7 days
- "last month" → past 30 days
- "last 2 weeks" → past 14 days
Content Filters
- "articles I read" → reading cluster (news, blogs, essays)
- "scientific articles" → research cluster (papers, docs)
- "code/research" → GitHub, Stack Overflow, docs
Keyword Filtering
- "articles about AI" → finds pages mentioning AI
- "scientific articles about climate" → finds research pages mentioning climate
Site-Specific
- "reddit threads" → reddit.com only
- "on medium" → medium.com only
- "twitter posts" → twitter.com only
Example Queries
"articles I read yesterday"
"articles about AI I read yesterday"
"scientific articles for the last week"
"research about machine learning this week"
"reddit threads last month"
"code repos I visited yesterday"
"on medium this week"
Usage
Run directly with a query:
python3 ~/.claude/skills/chrome-history/chrome_history_query.py "articles I read yesterday"
Or integrate into Claude Code when user asks:
- "Show me articles I read yesterday"
- "What scientific papers did I look at last week?"
- "Show reddit threads I visited last month"
- "Articles about AI from yesterday?"
Configuration
- Chrome History:
~/Library/Application Support/Google/Chrome/Default/History - Vault Location:
/Users/glebkalinin/Brains/brain - Filtered Sites: Social media, email, Google redirect wrappers
- Clustering: Automatic by domain type (reading, research, tools, events)
Exclusions
Automatically filters out:
- Social media: Facebook, Instagram, Twitter, TikTok, Reddit, LinkedIn
- Email: Gmail, Outlook
- Shopping: Amazon, eBay
- Google redirects: google.com/url wrappers
- Utility sites: FreeFeed, YouTube
What ships with it
3 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.
