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 | $0.00054 | $0.00804 |
| Opus 5.5 | $0.00022 | $0.00322 |
| Sonnet 5.5 | $0.00011 | $0.00161 |
| Haiku 4.5 | $0.00005 | $0.00080 |
Grade A, and why
vendor-review 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 6d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
vendor-review
Names like
~~chator~~project trackermean whichever tool of that kind is connected: a tool in one of your Hexis plugins, or one your agent has itself. The knowledge base is this workspace's knowledge base in Hexis, plus any other docs tool that is connected. When a source is not connected, skip it and say what you could not check.
Evaluate a vendor with structured analysis covering cost, risk, performance, and fit.
Usage
Ask your agent for the vendor-review skill by name, or just describe the job and it will pick the skill up. Give it:
What I Need From You
- Vendor name: Who are you evaluating?
- Context: New vendor evaluation, renewal decision, or comparison?
- Details: Contract terms, pricing, proposal document, or current performance data
Evaluation Framework
Cost Analysis (Total Cost of Ownership)
- Total cost of ownership (not just license fees)
- Implementation and migration costs
- Training and onboarding costs
- Ongoing support and maintenance
- Exit costs (data migration, contract termination)
Risk Assessment
- Vendor financial stability
- Security and compliance posture
- Concentration risk (single vendor dependency)
- Contract lock-in and exit terms
- Business continuity and disaster recovery
Performance Metrics
- SLA compliance
- Support response times
- Uptime and reliability
- Feature delivery cadence
- Customer satisfaction
Comparison Matrix
When comparing vendors, produce a side-by-side matrix covering: pricing, features, integrations, security, support, contract terms, and references.

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-review is a skill published in the GitHub repository Bevel-Software/Hexis (115 stars, last pushed today), licensed Apache-2.0. It adds 54 tokens to every session and 804 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 2026-10-10.

cost-model
Standardized cost-estimation framework for great-pm initiatives. Forces explicit LLM cost (across great-pm pipelines), human-equivalent comparison, infra delta, and time-to-ship. Output is parsable by /pm-burn and /pm-cost. great-pm version covers PM-side cost.
pm-pricing
Author or refresh a pricing plan — 2–3 monetization models with willingness-to-pay rationale per audience. Spawns pricing-strategist.
pm-cost
Estimate the cost of a proposed initiative BEFORE kicking it off — LLM cost projection across the 6-stage loop + human-equivalent + savingsx. Use this when an initiative might be too ambitious for the moment.
