What is pricing-refresh?

A maintainer-only workflow for comparing a model cost table with Anthropic's current pricing information. It also checks recent logs for model identifiers missing from the table.

Use it when explicitly refreshing or verifying pricing, reviewing rate differences, checking cache and fast-mode rates, and finding unknown model IDs in recent cost logs.

It helps keep recorded model rates accurate without changing them automatically or without confirmation.

Token cost

What it costs to keep this loaded

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	$0.00076	$0.00605
Opus 5.5	$0.00030	$0.00242
Sonnet 5.5	$0.00015	$0.00121
Haiku 4.5	$0.00008	$0.00060

Measured 11d ago against content hash 251fcdbede59, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

pricing-refresh 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.

What it actually says

Pricing refresh

Compare plugins/Codex-hermit/scripts/lib/pricing.ts to Anthropic's live docs and, only after explicit confirmation, edit the table. Do not run this on a schedule. Do not write anything under an operator's .Codex-hermit/.

Step 1 — Read the table

Read plugins/Codex-hermit/scripts/lib/pricing.ts. Record every PRICING key, its { input, output, cacheRead?, fast? } rates, the CACHE_WRITE_5M / CACHE_WRITE_1H / CACHE_READ multipliers, and PRICING_VERIFIED.

Step 2 — Fetch live sources

Load the bundled Codex-api skill. From its shared/live-sources.md, WebFetch these three URLs:

Models Overview
Pricing
Prompt Caching

Extract current model ids, per-MTok input/output, cache write (5m and 1h) and read multipliers, any per-model cacheRead absolute rate, and fast-mode rates.

Step 3 — Unknown ids in the log

From .Codex-hermit/cost-log.jsonl (this repo's own hermit dir, last 30 days of timestamp), list distinct model values that are not exact PRICING keys (dated <key>-YYYYMMDD snapshots of an existing key count as exact). Print them. Do not edit operator installs.

Step 4 — Diff

Print a rate-diff table: id, live input/output/cache/fast vs the file. Flag missing ids, stale rates, and a PRICING_VERIFIED date that is not today.

Stop here unless the operator confirms an edit.

Step 5 — Edit on confirmation only

If the operator explicitly confirms:

Edit plugins/Codex-hermit/scripts/lib/pricing.ts rates and keys to match the live table. Set PRICING_VERIFIED to today's date (YYYY-MM-DD).
Add a ### Fixed bullet under plugins/Codex-hermit/CHANGELOG.md [Unreleased]: rate table refreshed for the current generations.
Run cd plugins/Codex-hermit && bun test tests/pricing.test.ts.

Do not commit. Do not bump min_claude_code_version. Do not add a hook, a routine, or a config.json entry.

Changes

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.

pricing-refresh is a skill published in the GitHub repository gtapps/hermitd (79 stars, last pushed today), licensed MIT. It adds 76 tokens to every session and 605 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-02.
