Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00071 | $0.00600 |
| Opus 5.5 | $0.00028 | $0.00240 |
| Sonnet 5.5 | $0.00014 | $0.00120 |
| Haiku 4.5 | $0.00007 | $0.00060 |
Grade A, and why
deal-memo 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Deal Memo / Document Builder
Package the research from the other plays into a clean, audience-ready document.
When to use
"Write the investment committee memo," "make a one-pager on this deal," "turn what we found into something for the lenders/LPs," "draft the market study writeup."
First, ask one thing: audience & format
- Audience: Investment Committee, lenders, LPs/investors, internal, or partners? (Sets tone and what to emphasize.)
- Format: Word doc, PDF, slides, or one-page? (Use the matching builder/skill to produce the final file.) Default to the user's CLAUDE.md format preference if set.
Pull together
Gather outputs already produced (site one-pager, market study, comp table, assumptions memo, investor/owner brief). If something's missing and material, run that play first or flag the gap.

Structure of a strong IC memo
- Recommendation & ask — what's being decided, the recommendation, the specific ask (approve pursuit, approve capital, etc.).
- Deal snapshot — location, product, units, basis, business plan, key return metrics (as provided by Bristol's model — don't invent returns).
- Market — demand drivers, rents, supply pipeline, why this market now (from market study).
- Site — site specifics, zoning/entitlement, owner/control status.
- Underwriting assumptions — key inputs with sources and the sensitivity flags.
- Capital — debt + equity plan, target partners (from investor sourcing).
- Risks & mitigants — honest, specific; lead with supply and basis.
- Appendix — comp table, sources.
Output
- The finished document saved to the deal folder, in the requested format.
- Lead with the recommendation. Keep numbers sourced. Mark anything provided by Bristol's model as "per Bristol underwriting."
Guardrails
- Don't fabricate returns, comps, or figures. Use Bristol's model numbers as given; research-sourced numbers get citations.
- Present analysis, not investment advice; final decision and any legal/securities review stays with Bristol and counsel.
- Keep it honest about risks — a memo that hides the supply pipeline isn't doing its job.
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.

deal-memo is a skill published in the GitHub repository Fusion-Data-Company/bristol-os (1 stars, last pushed 4mo ago), licensed MIT. It adds 71 tokens to every session and 600 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 2026-08-31.
