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 | $0.00067 | $0.01139 |
| Opus 5.5 | $0.00027 | $0.00456 |
| Sonnet 5.5 | $0.00013 | $0.00228 |
| Haiku 4.5 | $0.00007 | $0.00114 |
Grade A, and why
vendor-agreement scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vendor Agreement
Draft a vendor or supplier services agreement for "$ARGUMENTS". Generate a comprehensive agreement covering scope of services, performance standards, data protection, and risk allocation.
Note: AI-generated legal content does not constitute legal advice. Consult a qualified attorney.
Arguments. $ARGUMENTS may contain the project name and optional flags. Take the first token as <project> and treat --skip-checks as a flag; never include flags in file paths. All paths below use <project>. If --skip-checks is present, skip the prerequisite check and, before writing any artifact, append one line to .metapowers/legal/<project>/skip-log.md: - <ISO timestamp> — <skill name> skipped prerequisite check for <artifact file> — reason: <reason or "none given">.
Prerequisites
Check that .metapowers/legal/<project>/00-assess.md exists. If it does not exist, stop and tell the user:
"Run an Assess skill first (e.g.
/legal:risk-assessment <project>) to generate the prerequisite assessment artifact."
Process
-
Read inputs:
- Read
.metapowers/legal/<project>/00-assess.mdfor risk and jurisdiction context - Read
${CLAUDE_PLUGIN_ROOT}/shared/contract-template.mdfor standard contract provisions
- Read
-
Identify engagement context:
- Nature of services being procured
- Vendor type (technology, consulting, staffing, facilities, etc.)
- Engagement duration and renewal expectations
- Data access and sensitivity level
- Criticality to business operations
-
Draft the following sections:
- Scope of Services — detailed description of services with reference to Statement of Work (SOW), deliverables and acceptance criteria, out-of-scope items explicitly excluded
- Performance Standards and SLAs — measurable performance metrics, reporting frequency and format, remedies for failure to meet SLAs (service credits, termination right), benchmarking rights
- Key Personnel — named key personnel (if applicable), replacement notice and approval requirements, non-solicitation of key personnel
- Pricing and Payment Terms — fee structure (fixed, T&M, milestone-based), payment schedule and invoicing requirements, late payment terms, price escalation provisions, most-favored-customer clause (if applicable)
- Expenses — reimbursable expense categories, pre-approval requirements and thresholds, documentation and receipting requirements
- Change Order Process — procedure for requesting changes to scope, impact assessment requirements (cost, timeline, resources), written approval requirements, dispute resolution for change order disagreements
- Confidentiality — mutual confidentiality obligations, definition of confidential information, permitted disclosures, return/destruction on termination
- Data Protection Obligations — data processing agreement (if vendor processes personal data), data security standards and certifications, breach notification requirements and timelines, data handling restrictions (location, subprocessing), audit and inspection rights
- Representations and Warranties — vendor authority and capacity, compliance with applicable laws, non-infringement of third-party IP, quality of services (professional standards, industry best practices), personnel qualifications and background checks
- Indemnification — IP infringement indemnification, negligence and willful misconduct, data breach costs and liabilities, third-party claims arising from vendor's services, indemnification process and control of defense
- Insurance Requirements — required coverage types (general liability, professional liability/E&O, cyber liability, workers' compensation), minimum coverage amounts, certificate of insurance requirements, additional insured status
- Termination — termination for convenience (notice period, wind-down fees), termination for cause (cure period, material breach triggers), termination for insolvency, partial termination rights (individual SOWs)
- Transition Assistance — vendor obligations during transition period, knowledge transfer requirements, cooperation with successor vendor, duration and cost of transition services
- Limitation of Liability — aggregate liability cap (typically total fees under the agreement), exclusion of consequential damages, carve-outs (IP indemnification, confidentiality breach, data breach, willful misconduct, bodily injury)
- Governing Law — choice of law, dispute resolution (escalation ladder: negotiation, mediation, arbitration/litigation), venue selection
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.

vendor-agreement is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed 2d ago), licensed MIT. It adds 67 tokens to every session and 1,139 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-21.
