A new skill is on as soon as it's created. Returns 409 SLUG_TAKEN if the slug belongs to another skill, including one you can't see, and 400 RESERVED_SLUG for a built-in skill's slug. Returns 400 INVALID_REFERENCE when uploadId isn't an upload or nothing was uploaded to it, and 400 INVALID_SKILL when the SKILL.md or archive can't be read. ## OpenAPI ````yaml https://api.parley.so/openapi.json post /skills openapi: 3.1.1 info: title: Parley API version: 1.0.0 description: >- Manage Parley's projects (matters or cases), accounts (client organizations), contacts (people), tasks, custom fields, notes, files, activity, automations, and skills. Records refer to each other as { type, id, name } references; writes take IDs. Errors are { error: { code, message, details } }, where code names what went wrong and each operation lists the codes it can return. In a query string, write a timestamp's offset as Z or %2B, because a raw + arrives as a space. The MCP server at /mcp offers the same data as a smaller set of tools. servers: - url: https://api.parley.so/v1 security: - bearerAuth: [] tags: - name: Projects description: >- A project is a matter or case: it groups the files, notes, activity, and tasks for one engagement, and links to the accounts and contacts it involves. - name: Accounts description: >- An account is a client organization.
