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 | $0.00131 | $0.01329 |
| Opus 5.5 | $0.00052 | $0.00532 |
| Sonnet 5.5 | $0.00026 | $0.00266 |
| Haiku 4.5 | $0.00013 | $0.00133 |
Grade A, and why
martech-contract-auditor 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.

MarTech Contract Auditor: Vendor Renewal and Negotiation Prep
This skill runs when the user is preparing for a vendor renewal or renegotiation. Search the web for current pricing benchmarks before writing anything. Do not rely on training data for pricing information.
HOW TO SET UP THIS SKILL
This skill works out of the box. No personal data required. Optionally add your current stack and contract details to get more specific output.
Optional context to provide:
- Current vendor, contract value, and renewal date
- How many seats, contacts, or records you are paying for vs. using
- What you actually use vs. what came with the package
- Whether you have a competing vendor evaluation in progress
What This Skill Does
Most MarTech vendors price on the assumption that buyers do not know their leverage. This skill helps you find it. It walks through six areas where renewal leverage exists, produces a negotiation brief, and delivers specific ask language you can use in the renewal conversation.
Step 1: Search for Current Pricing Benchmarks
Before building the negotiation brief, search for:
- Vendor name + "pricing" + current year
- Vendor name + "discount" or "negotiation tips"
- Vendor name + alternatives or competitors (to establish walk-away options)
- G2 or Capterra reviews mentioning pricing or contract experience
- Any recent funding, acquisition, or financial news about the vendor (financially pressured vendors discount more aggressively)
Note what you find. If pricing is not publicly available, note that and flag it as a negotiation signal: opacity in pricing means more room to negotiate.
Step 2: Build the Leverage Audit
Go through each category below and assess the user's position.
Usage vs. spend Is the user paying for capacity they are not using? Seats, contacts, records, API calls, or features that went unused last cycle are the strongest leverage point in any renewal. If usage is below 70% of contracted capacity, that is an opening.
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.
