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 | $0.00294 | $0.00294 |
| Opus 5.5 | $0.00118 | $0.00118 |
| Sonnet 5.5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
rosetta npm-channel-source-of-truth.instructions.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 22d 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.
What it actually says
npm channel source of truth
release.yml's "Determine npm release channel" step derives latest vs. prerelease (dist-tag next) entirely by parsing package.json's committed version field.
- Do not add a
workflow_dispatchinput, environment variable, or other CI-side flag that also selects or overrides the channel — that would let the two signals disagree. - A bare
MAJOR.MINOR.PATCHversion meanslatest. AMAJOR.MINOR.PATCH-nextor-next.Nversion means prerelease, published to thenextdist-tag. There are exactly two channels (#152): any other identifier, including the retiredalpha/beta/rc, fails the workflow loudly — never treat an unrecognized shape aslatestby default. - If a channel-adjacent input is genuinely needed later (e.g. limiting which registries get the floating tag), keep
package.json's version as the single source of truth for the channel decision itself, and layer the new input on top rather than replacing it.
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.
