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.

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 | $0.00165 | $0.04421 |
| Opus 5 | $0.00082 | $0.02210 |
| Sonnet 5 | $0.00033 | $0.00884 |
| Haiku 4.5 | $0.00016 | $0.00442 |
Grade A, and why
ot-cost-analysis 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 10d 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 — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OT Cost Analysis
Purpose and operating boundary
Build an auditable, formula-driven cost analysis organized by OT milestone. Separate total project cost, the non-Federal contribution, any consortium or administrative fee, the proposed payment amount, and the Government funding requirement. Use market evidence and arithmetic to support the Agreements Officer without originating the authority path, eligibility finding, significant-participation finding, successful-completion finding, or price-reasonableness determination.
Do not:
- Decide whether 10 U.S.C. 4021, 4022, or 4022(f) applies.
- Decide whether a participant is a nontraditional defense contractor, nonprofit research institution, small business, or significant participant.
- Invent a cost-share ratio, exceptional-circumstances determination, consortium fee, learning curve, indirect-rate structure, or proposed-price basis.
- State that a proposed amount is fair, reasonable, acceptable, competitive, aggressive, premium, or justified.
- Treat a BLS or CALC+ benchmark as the performer's required rate.
- Call the output a FAR 15.404 analysis or an IGCE.
When a sentence would conclude the Agreements Officer's judgment, replace it with the source data, the variance, the scenario range, and the decision left open.
Reference map
Load only the references needed for the active workflow:
- authority-and-cost-sharing.md before classifying or applying a cost share.
- labor-and-costing-methods.md before deriving labor, materials, scenarios, ceilings, fees, or funding timing.
- data-source-operations.md before mapping SOCs or calling BLS, CALC+, or Per Diem operations.
- workbook-specification.md in full before generating the workbook.
- professional-product-standard.md before generating the workbook.
- validation-gates.md before building and again before delivery.
- runtime-adaptation.md when collecting structured answers, locating tools, selecting a calculation engine, or delivering files.
What ships with it
12 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

ot-cost-analysis is a skill published in the GitHub repository 1102tools-dev/federal-contracting-skills (25 stars, last pushed 9d ago), licensed MIT. It adds 165 tokens to every session and 4,421 once invoked, about $0.0008 per session on Opus 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 2026-08-30.
