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 | $0.00163 | $0.36161 |
| Opus 5 | $0.00081 | $0.18080 |
| Sonnet 5 | $0.00033 | $0.07232 |
| Haiku 4.5 | $0.00016 | $0.03616 |
Grade A, and why
cap-table 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 3d 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.

Cap-Table Skill
Model cap-table mechanics for founders so they understand what their term sheets, SAFEs, and convertible notes actually do to their ownership — before they sign. Produce rule-pack-cited math for SAFE conversion, convertible-note conversion, priced-round dilution, option-pool top-ups, anti-dilution, and Israeli ↔ Delaware flips. Every counsel-review item links back to a primary source (YC SAFE primer, NVCA model docs, Israeli Companies Law / Income Tax Ordinance, etc.). Tone is founder-first: a candid coach who's read the documents you can't be expected to read.
Reliance Boundary (mandatory)
For any eligibility, qualification, or status determination that turns on tax or legal facts the cap-table data cannot settle — QSBS (IRC §1202), Israeli §102 track / holding period, IIA obligations, or any rule carrying counsel_review — state the cited fact (the date window, threshold, or clock) and stop there. Never conclude that the founder does or will qualify ("yes, you qualify", "you're eligible", "strong eligibility posture"). The date or threshold is a fact you may assert with its citation; the conclusion is a counsel determination — present it as such and emit a counsel item. This holds whether the engagement runs the full pipeline, fast-assess, or a one-line directional answer: the boundary is about what you may conclude, not how deep the analysis went.

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.
