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 | $0.05278 | $0.05278 |
| Opus 5.5 | $0.02111 | $0.02111 |
| Sonnet 5.5 | $0.01056 | $0.01056 |
| Haiku 4.5 | $0.00528 | $0.00528 |
Grade A, and why
noon-sight 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 2mo 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Purpose
noon-sight is an MCP server on Cloudflare Workers that aggregates what a site publishes and how it is read. Access is gated by Cloudflare Zero Trust.
Two kinds of question live here, and which one a source answers settles the shape of its tool before anything else about it is decided.
Traffic is quantitative. One event says nothing on its own; only the aggregate informs. So a traffic tool groups by a closed list of questions, counts, and answers for a period against the equally long one before it — the change is what makes a number worth reading. Analytics only ever meets someone who already arrived, Search Console counts the ones who were shown the site and did not come, and Cloudflare sits in front of the request and sees whoever asked, including everything that runs no JavaScript and so reaches neither.
Content is qualitative. One item carries the whole meaning and an aggregate destroys it: 8 posts about Ruby tells a reader nothing they did not already know, while the sentence that post actually made is the thing worth having. So a content tool returns the content itself within a window and leaves the reading to whoever asked. Counting is not withheld from them — it is theirs to do, on the text they now hold.
A source earns its place by answering what the others structurally cannot. Counting what should have been read, or returning what should have been counted, is the one mistake no amount of care downstream repairs.
Minimal by design. Implement only the tool being asked for. Feature completeness is not the goal; staying small is. Before adding an abstraction layer, a config knob, or code for a case that might come later, confirm it is needed now.
No SPEC.md. Correctness is expressed by vitest tests, not by specification documents.
Working together
Work runs in two movements, and the boundary between them carries more weight than the commands do.
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.
