description	Create protocol adapter packages for Sol. Use when defining a new protocol adapter and you need reusable templates, validation rules, and anti-pattern guidance based on Sol's adapter architecture.

Sol Skill Creator

Use this skill to design and standardize protocol adapter packages built on top of sol.

Prerequisites

• sol skill is available as the base execution contract.
• Target adapter scope is clear (protocol name, URL detection, operation model, auth requirements).

Output Contract

An adapter package created with this skill should include:

• adapter.py — Main adapter implementation
• pyproject.toml — Package metadata with entry point
• tests/ — Unit tests for adapter
• README.md — Usage documentation

Optional files are allowed only when they add real reusable value.

Core Workflow

1. Start from user-provided protocol input:
   • record protocol name (e.g., "graphql", "grpc")
   • identify URL detection strategy (scheme-based, content probing)
2. Discover protocol behavior before drafting code:
   • search official docs to confirm endpoint patterns
   • test with manual HTTP calls to understand request/response format
   • identify schema discovery mechanism (if any)
3. Detect authentication requirement explicitly:
   • probe with minimal call and inspect response
   • if auth-protected, record required model (bearer, API key, custom)
   • document auth header format
4. Fix the adapter interface:
   • protocol name (protocol_name())
   • detection priority (priority())
   • URL pattern (can_handle())
   • operation discovery strategy (fixed catalog vs. dynamic)
5. Implement adapter methods:
   • can_handle(): URL detection logic
   • list_operations(): Return available operations
   • describe_operation(): Return operation details
   • execute(): Perform actual API call
6. Add comprehensive tests:
   • protocol detection tests
   • operation discovery tests
   • execution tests with mocked responses
   • auth header injection tests
7. Register via entry point in pyproject.toml:
   • [project.entry-points.'sol.adapters']
   • myprotocol = "sol_myprotocol.adapter:MyProtocolAdapter"
8. Write README.md with usage examples
9. Test installation and verify sol <url> -h works

Hard Rules

• Protocol name must be unique (one protocol = one adapter).
• All Adapter ABC methods must be implemented.
• can_handle() must be deterministic and fast.
• execute() must inject auth_headers into HTTP requests.
• Tests must achieve 80%+ coverage.
• Entry point must match protocol name.
• Do not assume URL format; probe and verify.
• Do not hardcode credentials; use auth_headers parameter.
