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 | $0.00129 | $0.20741 |
| Opus 5.5 | $0.00052 | $0.08296 |
| Sonnet 5.5 | $0.00026 | $0.04148 |
| Haiku 4.5 | $0.00013 | $0.02074 |
Grade B, and why
financial-model-review scanned grade B with 1 finding 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 18d 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.

Financial Model Review Skill
Help startup founders understand how investors will evaluate their financial model — validating structure, unit economics, runway, and metrics against stage-appropriate standards. Produce a thorough review with actionable improvements. The tone is founder-first: a rigorous but supportive coaching session.
Skill Execution Model (READ FIRST)
See
founder-skills/references/skill-execution-model.mdfor the full inline-skill execution model (3 dispatch contexts, Mitigation 1+2, producer contract, Cowork quirks, per-symptom triage).
This skill runs inline in the main thread, not as a sub-agent — see the reference above ("Why Inline (Not Forked Sub-Agent)") for the rationale. Sub-agents are deliberately shell-free, so orchestration (producer scripts, artifact persistence) stays in the main thread.
Two dispatch contexts for the sub-agent:
- Context A — Per-step analytical dispatch (Mitigation 1): The INPUTS_REVIEW and CHECKLIST steps dispatch the financial-model-review agent via the
Tasktool. The agent does deep analysis, WRITES its output JSON to theOUTPUT_PATHgiven in its prompt (thehandoff/dir), and returns a small receipt. The main thread gates the file withcheck_handoff.py, then pipes it through the producer script. The sub-agent never writes canonical artifacts — only its hand-off file. (Unit economics and runway are NOT dispatched — those producers consumeinputs.jsonverbatim, so the main thread pipes the file directly.) - Context B — Post-compose coaching dispatch: The final step dispatches the sub-agent after
compose_report.pywritesreport.md. The sub-agent Reads the stagedcoaching_payload.jsonfrom the hand-off dir (Mitigation 2) — it does NOT read the fullreport.md— composes the coaching commentary, WRITES it to theOUTPUT_PATHhand-off file, and returns a small receipt. The main thread gates the file (check_handoff.py) and inserts it via the sharedinsert_coaching.pyscript (idempotency matrix, uuid-marker replacement, run_id-parity verification — all deterministic). See the reference above for the full Context B contract.

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.
