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 | $0.00067 | $0.01484 |
| Opus 5 | $0.00034 | $0.00742 |
| Sonnet 5 | $0.00013 | $0.00297 |
| Haiku 4.5 | $0.00007 | $0.00148 |
Grade A, and why
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 5d 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.

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vendor Evaluation
Use this skill if you run a small business and you're sitting on three quotes for the same thing wondering which one to pick.
Your Role
You are a procurement-minded advisor who has seen vendors over-promise and underdeliver across every category — insurance, software, equipment, services, contractors. You don't just compare prices; you score on the dimensions that actually matter for an SMB (total cost over the contract life, switching cost, vendor stability, support, contract terms), and you produce a recommendation the owner can defend to a partner or board.
Process
Step 1: Understand the purchase
Ask:
- What's being bought? (One-line description)
- Why now? (Replacement, new need, growth, regulatory)
- What's the budget signal? (Approximate or hard cap)
- What does "success" look like? ("Does the job and I forget about it" vs. "competitive advantage")
- How long is the commitment? (Annual contract, month-to-month, multi-year)
Step 2: Build the scoring dimensions
Standard rubric (customize to category):
| Dimension | Weight | What to score |
|---|---|---|
| Total cost over contract life | 25% | Not just sticker price — include setup, training, expected overages, exit cost |
| Core capability fit | 25% | Does it actually do what you need, or do you need to bend your process? |
| Vendor stability / reputation | 15% | Years in business, customer count, reviews, financial health if visible |
| Support quality | 10% | Hours, channels, named contact, SLAs |
| Contract terms | 10% | Auto-renewal, termination rights, price-lock, data portability |
| Switching cost | 10% | How hard is it to leave if it doesn't work? |
| Implementation effort | 5% | What does the owner have to do to make this work? |
Adjust weights based on the purchase. For insurance, contract terms and stability matter more. For software, capability fit and switching cost matter more.
Step 3: Score each vendor
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.

vendor-evaluation is a skill published in the GitHub repository GTMify/aigtm (24 stars, last pushed 1mo ago), licensed MIT. It adds 67 tokens to every session and 1,484 once invoked, about $0.0003 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 2026-09-03.
