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 | $0.03512 | $0.03512 |
| Opus 5 | $0.01756 | $0.01756 |
| Sonnet 5 | $0.00702 | $0.00702 |
| Haiku 4.5 | $0.00351 | $0.00351 |
Grade A, and why
mcp-freestyle 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 6d 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 — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — mcp-freestyle
This file is mutable and iterative. Update it after every Claude mistake or newly discovered convention. Target: < 200 lines.
Relationship with the global CLAUDE.md: this file is loaded in addition to the global (
~/.claude/CLAUDE.md+ enterprise policy) — on conflict the global/enterprise rule wins. Omitted here (your global already covers them): none.
Session start — read first, in order
PLAN.md— where the project stands now (if present)docs/LEARNINGS.md— rules learned from past corrections (apply them!)docs/VISION.md— goal, scope, non-goals (if present)- The artifacts of whatever is in progress per
PLAN.md
Capture at checkpoints (don't wait to be asked)
The agent can't perceive "end of session" — so capture at the work boundaries it can see, and propose it proactively there without waiting for the user:
- Before a
git push, a tag, or a release — the highest-value, most reliable moment: pause and capture before shipping. - When a
PLAN.mdmilestone is completed, or after a substantial chunk of work.
You can also trigger it yourself any time with /groundrules:checkpoint.
At that moment, three questions, each routed to where it belongs:
- Decided anything structural? →
/groundrules:add-adr(docs/decisions/) - Learned something that changes how to work here (incl. a blocker that cost 30+ min, with its fix)? →
/groundrules:learn(docs/LEARNINGS.md) - Caught the agent repeating a mistake, hallucinating, or drifting? → note it in
docs/AGENT-EVALS.md(if present) and add the guard here or in.claude/rules/
Capture beats memory: if it's not written to the repo, it's gone next session.
Description
A Model Context Protocol server that reads data from a FreeStyle glucose sensor.

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.

mcp-freestyle CLAUDE.md is an instructions file published in the GitHub repository lozit/mcp-freestyle (0 stars, last pushed 18d ago), licensed MIT. It adds 3,512 tokens to every session, about $0.0176 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
