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 | $0.00154 | $0.05186 |
| Opus 5 | $0.00077 | $0.02593 |
| Sonnet 5 | $0.00031 | $0.01037 |
| Haiku 4.5 | $0.00015 | $0.00519 |
Grade A, and why
mywhoosh-upload 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 11d 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 — 424 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Getting a workout into MyWhoosh
MyWhoosh has no API. The only supported route is the browser flow below, driven through Claude in Chrome. Everything here was confirmed in a real session.
Two things make this different from an ordinary browser task:
EXPORT TO MYWHOOSHspends a slot credit. Credits are finite and there is no undo. You must stop and get explicit confirmation before clicking it.- It is UI automation, so it will rot when MyWhoosh redesigns something. Each step below says what you should expect to see. If what you see doesn't match, stop and report which step's expectation failed and what was on screen instead. Do not improvise around a mismatch — a stray click on the chart creates phantom blocks in the workout.
Why the FTP has to come first
A .zwo stores power only as fractions of FTP. The watts actually ridden
are fraction × the FTP MyWhoosh has. So if the session is "3 x 10 min at
232 W" and you render against 255 W but MyWhoosh is set to 200 W, every target
is ridden at 182 W — about 22% too easy — and nothing anywhere reports a
problem. The file is valid; it is just scaled to a different athlete.
Unless the session is written in percentages. If every block is
power_pct, the percentages are the intent: they render to the same fractions
under any FTP, so the builder's FTP changes only the watts displayed and the
TSS/IF figures — nothing stored is rescaled. Still read it and still report a
disagreement, but do not halt over one. The FTP is load-bearing exactly when the
athlete gave watts.
get_cycling_ftp reads Garmin's profile, which is a different number and
frequently stale. It is a starting point, not the answer.
Since you are opening the browser anyway, read MyWhoosh's own FTP out of the builder and render against that (Step 3). That makes the fractions correct by construction, rather than correct by assumption.
Consequence for ordering: draft the session first, but do not render until after Step 3. If the athlete gave targets in watts, those watts are the fixed intent, and the FTP is what converts them.
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.

mywhoosh-upload is a skill published in the GitHub repository elias-ramzi/ClaudeCyclingMCP (0 stars, last pushed 18d ago), licensed MIT. It adds 154 tokens to every session and 5,186 once invoked, about $0.0008 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.
