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 | $0.00091 | $0.04665 |
| Opus 5 | $0.00046 | $0.02332 |
| Sonnet 5 | $0.00018 | $0.00933 |
| Haiku 4.5 | $0.00009 | $0.00466 |
Grade A, and why
negotiation-game-theory 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 5d 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 — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Negotiation Game Theory
Every negotiator has a mathematical bottom line -- the minimum outcome they will accept before walking away. Most never calculate it. They arrive at the table armed with aspirations and anxiety, anchoring on round numbers or gut feelings, when the strategic structure of the negotiation is already fully determined by three quantities: what each side gets if the deal fails, what the deal creates if it succeeds, and how each side values incremental gains. Finding the other party's bottom line -- their true minimum acceptable outcome -- is worth more than any persuasion technique, any rapport-building exercise, any tactical concession. The relationship-based approach taught by Fisher and Ury (see Win-Win Negotiation) handles the human dynamics superbly. This skill addresses the strategic geometry underneath.
The Framework
Negotiation as a Cooperative Game
A negotiation between two parties, A and B, is a cooperative game with a specific structure. If the negotiation succeeds, it produces a total payoff that exceeds what either party could achieve alone. If it fails, each party falls back to their standalone value -- what they can earn without the other.
Three values define every negotiation:
| Variable | Meaning | Example (Series A Fundraise) |
|---|---|---|
| Total deal value | What the cooperation produces | $20M company valuation created by capital + execution |
| A's standalone value | What A gets if the deal fails | Founder bootstraps at $2M valuation growth/year |
| B's standalone value | What B gets if the deal fails | Investor deploys capital elsewhere at 15% expected return |
The fundamental precondition for any negotiation: the deal must create surplus. The total deal value must exceed the sum of both parties' standalone values. If it does not, there is nothing to negotiate -- both sides are better off walking away. This seems obvious, yet founders regularly enter negotiations where no surplus exists (the investor's alternative returns exceed what the startup can plausibly deliver, or the customer's internal solution outperforms the vendor's offering).
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.

negotiation-game-theory is a skill published in the GitHub repository fatihguner/foreman (50 stars, last pushed 6d ago), licensed MIT. It adds 91 tokens to every session and 4,665 once invoked, about $0.0005 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 2026-09-06.
