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.

Security

Grade A, and why

web-data 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 yesterday.

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.

Web data jobs with Spidra

The Spidra server already tells Claude which tool does what. This skill is about doing the whole job well: the steps, the defaults, and what a good answer looks like. Every Spidra call spends the user's credits, so the habit throughout is a small first step, then more only if the user wants it.

Businesses on a map, products, listings, jobs, reviews, profiles:

  1. spidra_find_templates with a word or two from the request. Spidra adds templates often, so look before deciding there isn't one.
  2. spidra_get_template to see its inputs. Fill them from the request; don't invent inputs it doesn't list.
  3. For anything over a few dozen rows, run it with "estimate": true first and tell the user what it will cost.
  4. Run it. When the user gave no number, start small (10 to 20 rows) and say more are available.
  5. Answer with a Markdown table of the columns the user asked for, then one line with how many rows came back and the credits used. Offer the rest of the fields or more rows; don't dump them.

If no template fits, a link from the site with "output": "json" and no prompt often comes back with the page's data already in named fields. Try that before writing an extraction prompt.

Research with sources

When you already know the page that answers the question (official docs, release notes, a company's own page), read it directly: scrape it with no prompt to get Markdown for 1 credit, and summarize it yourself. A summarizing prompt on a long page can cost 20 credits or more.

Otherwise:

  1. spidra_search first. Use the news source for anything recent, and a time range when the user says "this week" or "latest".
  2. Answer from the snippets when they're enough. When they aren't, read the 3 to 5 most useful results in one spidra_batch_scrape as Markdown, not one scrape each and not every result.
  3. Write a short answer where each claim links to the page it came from, and say how recent the sources are. If sources disagree, say so.

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.
