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 | $0.00094 | $0.01727 |
| Opus 5 | $0.00047 | $0.00864 |
| Sonnet 5 | $0.00019 | $0.00345 |
| Haiku 4.5 | $0.00009 | $0.00173 |
Grade A, and why
batna-zopa 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.

BATNA & ZOPA
Overview
BATNA (Best Alternative to a Negotiated Agreement) is the value of your best fallback if no deal happens — the floor below which you walk away. A negotiator without a clear BATNA negotiates from fear; with one, from position.
ZOPA (Zone of Possible Agreement) is the overlap between what each side will accept. If it exists, a deal is possible; if not, the question is structural change — not harder negotiating.
Composes with anchoring, signaling-games, repeated-games-reputation, and prisoners-dilemma.
When to Use
- Any non-trivial negotiation: term sheets, salary, partnership, M&A, vendor contracts, customer pricing
- You feel pressure to take a deal that "feels bad" — usually a sign your BATNA is weak or not modeled
- Assess whether a deal can happen before investing time in tactics
- Raising in the 2024–2026 AI market (term sheets, SAFEs) or committing to a GPU-cloud / compute contract, where FOMO and "capacity is scarce" pressure obscure your real alternative
Not when: purely emotional/non-transactional disputes; cultures where direct BATNA discussion is taboo.
Coaching Novices (Adaptive Front Door)
- Engine mode: user has a concrete deal → run The Process directly.
- Coach mode: user is unfamiliar → guide step by step.
In Coach mode, respond one step at a time. Each [WAIT] is a hard stop — output only that step's question, then stop.
- One-line: BATNA = your walk-away value; ZOPA = the range where both sides say yes.
- Check fit: relationship-only situations → point elsewhere.
- "What negotiation are you in right now?"
[WAIT — do not advance until user responds]
- One question at a time: What's your BATNA? What's theirs? Where's the overlap?
[WAIT — do not advance until user responds]
- Name the specific opening offer and walk-away point they've identified.
[WAIT — do not advance until user responds]
What ships with it
4 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.

batna-zopa is a skill published in the GitHub repository deciqAI/knowledge-skills (10 stars, last pushed 8d ago), licensed MIT. It adds 94 tokens to every session and 1,727 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 2026-08-31.
