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 | $0.00039 | $0.01390 |
| Opus 5 | $0.00019 | $0.00695 |
| Sonnet 5 | $0.00008 | $0.00278 |
| Haiku 4.5 | $0.00004 | $0.00139 |
Grade A, and why
negotiation-prep-skill 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 12d 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.

Skill Name
Procurement Negotiation Preparation Skill
Purpose
This skill helps AI build a structured negotiation brief from supplier proposals, pricing, performance, contract risks, alternatives, stakeholder priorities, and approval limits.
It supports preparation. It does not negotiate autonomously or make final trade-off decisions.
Composability
This skill is standalone. If other Procurement AI Assistant skills are installed, the AI may combine relevant skills for a multi-step procurement request. Do not assume another skill is available; preserve this skill's own guardrails and human review points.
Core Principle
Good negotiation starts before the meeting.
The workflow is:
Define Objectives -> Gather Evidence -> Map Leverage -> Prioritize Asks -> Design Trades -> Anticipate Pushback -> Set Fallbacks -> Obtain Approval
When to Use
Use this skill for:
- Renewal negotiations
- Supplier price increases
- New-contract negotiations
- Contract-risk negotiations
- SLA and service-credit negotiations
- Implementation and transition negotiations
- Professional-services rates
- Volume and licence negotiations
- Supplier performance remediation discussions
Do Not Use This Skill For
Do not use it to:
- Invent leverage or alternatives
- Recommend deception, coercion, collusion, or unethical tactics
- Make unauthorized commitments
- Ignore public procurement fairness or communication controls
- Decide final concessions
- Contact suppliers without approval
Required Inputs
- Supplier proposal
- Current and historical pricing
- Contract and renewal terms
- Performance data
- Business priorities
- Must-haves and preferences
- Alternatives and switching cost
- Market evidence
- Supplier dependencies
- Internal approval limits
- Timing and stakeholders
Workflow
Step 1: Define the Negotiation Objective
Identify:
- Desired outcome
- Minimum acceptable outcome
- Non-negotiables
- Preferences
- Risks to protect
- Timeline
Step 2: Build the Fact Base

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-prep-skill is a skill published in the GitHub repository arunbalajiraju-proc/procurement-ai-assistant (13 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 1,390 once invoked, about $0.0002 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.
