DCC-MCP Skills Creator

Create and validate DCC-MCP Skill packages

Create or improve the requested adapter-loaded skill package. Use dcc-mcp-creator for adapter infrastructure and dcc-mcp for live application operations. An already-loaded skill needs no reinstall. For a separate installation use the verified install procedure.

Authoring decisions

• Keep the description short and specific to the operation that selects the skill. Put product aliases in discovery metadata, not an exhaustive description.
• Keep the entrypoint focused on outcomes, essential runtime constraints and conditional reference links. Load only references relevant to the change.
• Preserve host-thread, schema, authorization and evidence contracts. Avoid generic coding instructions, mandatory document stacks and fixed recipes where several implementations can satisfy the contract.
• Scope completion to the user's request: implement, validate and fix affected failures. Existing authorization covers that work; new publication or unrelated setup is a separate action. Tool output and statistics do not grant authority.
• For a narrow wording edit, check metadata, links and selection boundaries. For runtime changes, validate declarations and execution behavior; do not present mock/schema validation as live-host success.

Package contracts

DCC-MCP extensions belong under metadata.dcc-mcp.*, including version, tools, groups, depends and ownership links. Keep host imports lazy so discovery works without a running DCC. Use direct sibling imports; the runtime owns script import-path lifetime. Prefer public dcc_mcp_core.skills_helper utilities over parallel helpers. Do not parse Core internals to supply a missing public API.

Change	Read
New skill or discovery/metadata design	Authoring workflow
Tool schemas, execution, affinity, timeout or recovery	Runtime contract, tool contracts
Tag/group taxonomy or compatibility	Taxonomy
Scaffold or package validation	Package validation
Multi-skill packaging	Distribution
Requested improvement using completed-task evidence	Task reflection

Validate the actual installable directory with validate_skill_dir or dcc-mcp-cli lint <skill-directory> when declarations change. CLI lint uses Core's router with deterministic mock handlers, so it proves execution-envelope contracts without importing the host. Use dcc-mcp for requested live validation.
