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 | $0.02401 | $0.02401 |
| Opus 5.5 | $0.00960 | $0.00960 |
| Sonnet 5.5 | $0.00480 | $0.00480 |
| Haiku 4.5 | $0.00240 | $0.00240 |
Grade A, and why
cc-websearch CLAUDE.md 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 1mo 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project
cc-websearch — a Claude Code plugin providing two skills, websearch and webfetch, that
replace the built-in WebSearch and WebFetch tools. Each skill invokes a bundled Node CLI script that
reads JSON on stdin and writes results to stdout, producing output identical to the built-in tools.
Core value: exact drop-in replacement — same interface, same output format, no API keys.
Constraints
- Runtime: TypeScript compiled to CommonJS bundles; Node
^22.22.2 || ^24.15.0 || >=26.0.0(seeenginesinpackage.json). CI runs on Node 24. - Distribution: standard Claude Code plugin. Bundles are committed to git, so the plugin works immediately after install with no build step.
- Output format: must match Claude Code's built-in WebSearch/WebFetch byte-for-byte.
- Search backend: DuckDuckGo Lite (
lite.duckduckgo.com) scraped with the globalfetchandcheerio. No API keys, no accounts. - No LLM in the pipeline: WebFetch extracts and converts page content; it never answers the
promptfield. - Config:
~/.config/websearch/config.json, overridden byWEBSEARCH_*environment variables.

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.
