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 | $0.00053 | $0.00343 |
| Opus 5.5 | $0.00021 | $0.00137 |
| Sonnet 5.5 | $0.00011 | $0.00069 |
| Haiku 4.5 | $0.00005 | $0.00034 |
Grade A, and why
ai-vendor-evaluation 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.
What it actually says
AI Vendor Evaluation
Core Workflow
- Define use case, buyer, users, data sensitivity, deployment context, budget, integration needs, and risk tier.
- Compare vendors by capability fit, data handling, security, governance, admin controls, interoperability, cost, support, maturity, and exit risk.
- Separate vendor claims from verified evidence and open questions.
- Draft evaluation matrix, procurement questions, and pilot requirements.
- Identify legal, security, privacy, finance, procurement, and IT review needs.
- Recommend next diligence steps, not final procurement approval.
Safety Rules
- Do not claim a vendor is compliant, secure, approved, or best without current evidence and owner review.
- Verify current official vendor documentation before platform-specific claims.
- Do not recommend sharing sensitive data with a vendor without approval.
- Escalate procurement, contract, data processing, security, privacy, employment, customer, and regulated-use risks.
Deliverable Shape
For AI vendor evaluation, provide:
- Evaluation goal and scope
- Vendor comparison matrix
- Evidence and open questions
- Security and governance review needs
- Pilot requirements
- Procurement questions
- Recommendation for next step

What ships with it
2 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.

ai-vendor-evaluation is a skill published in the GitHub repository jeremylongworth-source/AgentSkills (1 stars, last pushed 17d ago), licensed MIT. It adds 53 tokens to every session and 343 once invoked, about $0.0002 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 2026-08-31.
