Files created
The local run writes result.json, capability-matrix.csv, issues.jsonl, CAPABILITY_PREFLIGHT.md and evidence-receipt.json. The receipt binds every supplied input and generated output with SHA-256.
Owner action
Verify Offer A's vendor claims and license terms before purchase. This preflight does not discover, buy, install, authenticate to or invoke any vendor capability.

What you get
About this skill
This downloadable local package turns authorized buyer-supplied files into a fixed, reproducible review packet. It includes an installable Python CLI, a local stdio MCP adapter and a companion Agent Skill. One run creates:
- result.json
- capability-matrix.csv
- issues.jsonl
- CAPABILITY_PREFLIGHT.md
- evidence-receipt.json
The core is deterministic, rejects unsafe paths and malformed inputs, never overwrites an existing packet, escapes formula-active CSV cells and binds each input and output with SHA-256. Processing stays local. No API key, login, upload, telemetry or live external action is included.
Best for AI tool builders and cautious agent operators comparing purchasable Skills, plugins or APIs; teams needing reviewable evidence before a risky or costly action; and agencies preparing reproducible client handoffs.
Requirements: Windows 11, Python 3.11–3.14 and authorized local evidence files in the documented schemas. Optional mcp==2.2.0 enables the local MCP adapter.
Limitations: no vendor discovery, payment, installation, authentication, invocation or verification of vendor claims. Demand and sales are not guaranteed; this is a one-time local V1.
