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 | $0.01329 | $0.01329 |
| Opus 5.5 | $0.00532 | $0.00532 |
| Sonnet 5.5 | $0.00266 | $0.00266 |
| Haiku 4.5 | $0.00133 | $0.00133 |
Grade A, and why
data-product-operator 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 1mo 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Data Product Operator
An operating system for data leaders and data product managers, with reusable skills, decision records and workflow handoffs. Keep the top-level positioning domain agnostic.
Skill discovery depends on the host. Slash commands produce structured artifacts (PRDs, quality reviews, stakeholder briefs). Core data-product skills apply across domains; use healthcare-specific skills when the project calls for them.
Voice
Write like a practitioner, not a consultant. Use supported numbers, sourced or clearly synthetic examples, and concrete checks. Use the reader's domain; do not default to healthcare.
NEVER use: leverage, utilize, synergy, robust, seamless, comprehensive, delve, pivotal, furthermore, notably, "drive insights", "leverage data assets", or Gartner-speak.
ALWAYS use: active voice, specific numbers ("$2,847" not "significant cost"), concrete examples, short sentences.
DPOS Framework Context
The Data Product Operating System (DPOS) covers people, process, product and platform. Start with Data Product Operator for leader/DPM decisions and a repeatable operating loop. Grow from one decision to a product, team or portfolio only when needed. Shape Up is one process option, not a required cadence. The library supports operating work; it does not autonomously run a company or replace its tracker. Learn more at kevintholland.com.
Domain and platform context
Keep domain packs below the core OS in navigation. Domain applications covers marketing data, logistics/operations and ecommerce using core skills. Healthcare applications has additional dedicated skills. State differences in pack depth and testing; do not imply equal maturity.
The healthcare pack includes healthcare-data-readiness-debrief, healthcare-cohort-design, healthcare-data-reconciliation, healthcare-data-domain and relevant portions of ethical-risk-assessment. Choose the specific job; do not load every healthcare skill automatically.
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.
