Complete infer to disable-model-invocation migration in GitHub org custom agents

[Copilot]

The migration from infer to disable-model-invocation was incomplete—generateAgentMarkdown() still generated the deprecated infer attribute in frontmatter for custom agents fetched from GitHub organizations.

Changes

Mapping logic in githubOrgCustomAgentProvider.ts:

• Map infer: false → disable-model-invocation: true
• Map infer: true|undefined → omit attribute (default behavior)
• Remove deprecated infer output

Interface documentation in githubService.ts:

• Mark infer field as @deprecated with mapping semantics
• Retain field since backend API still sends it

Test coverage:

• Verify infer: true produces no attribute output
• Verify infer: false produces disable-model-invocation: true
• Verify minimal agents omit both old and new attributes

Example

Backend response with infer: false:

const agentDetails: CustomAgentDetails = {
  name: 'reviewer',
  infer: false,  // Backend field
  // ...
}

Generated frontmatter:

---
name: Reviewer
disable-model-invocation: true  # New attribute
---

Pull request overview

This PR completes the migration from the deprecated infer field to disable-model-invocation for GitHub organization custom agents. The backend API still sends the infer field, but the frontend now properly maps it to the new attribute when generating agent markdown files.

Changes:

• Map backend's infer field to disable-model-invocation attribute in generated frontmatter (infer: false → disable-model-invocation: true, while infer: true or undefined omits the attribute)
• Update planAgentProvider.ts to use disableModelInvocation instead of the deprecated infer field
• Add comprehensive test coverage for both infer: true and infer: false cases
• Update agent customization documentation to reflect the new attributes (user-invokable and disable-model-invocation)
• Add support for additional skill directory locations (.agents/skills/ and .claude/skills/)
