BB greenhelix-agent-interoperability-bridge
The Agent Interoperability Bridge: Connecting GreenHelix Agents to x402, ACP, A2A, MCP, Visa TAP, Google AP2/UCP, PayPal Agent Ready, and OpenAI ACP Ecosystems. Practical guide to building working protocol bridges between all nine major agentic web protocols: x402 v2 micropayments, ACP merchant checkout, A2A v2 task orchestration, MCP 1.5+ tool integration, Visa TAP card-network payments, Google AP2 real-time payments, UCP service orchestration, PayPal Agent Ready, and OpenAI ACP commerce flows. Includes detailed code examples with Python bridge classes for protocol translation, cross-protocol identity mapping, intelligent payment routing, and event bri

How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 65/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 10Execution cost. Instruction body is 35761 tokens: crowds the task out of the window
- 20When it triggers. No condition that starts the skill
- 60Tools and files. Uses tools (bash, web, python) that frontmatter does not declare
- 100Steps. 76 steps
- 100Result and completion. Output format and completion criterion are stated
- 100Failures and branches. 9 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Running it twice. Mutating operations check current state
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 17 top-level sections: this looks like several domains in one skill
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
