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	$0.02162	$0.02162
Opus 5	$0.01081	$0.01081
Sonnet 5	$0.00432	$0.00432
Haiku 4.5	$0.00216	$0.00216

Security

Grade A, and why

fetcher-skills AGENTS.md scanned grade A with 1 finding 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 8d 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.

What this repo is

Agent skills for fetcher.sh — a pay-per-call web-data API. Each service (Twitter/X, TikTok, Instagram, YouTube, Reddit, Google Search, Google Maps, Google News, Google Play, App Store, Yelp) is its own skill, plus one shared fetcher skill for payment and MCP setup. Every skill talks to a real, live host — https://<service>.fetcher.sh — there are no mock endpoints or placeholder actor IDs.

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.
