Cause (Documented platform behavior): Copilot CLI does not support classic PATs; requires fine-grained PAT owned by a personal account with 'Copilot Requests' permission, or OAuth (gho_) login. Env precedence: COPILOT_GITHUB_TOKEN, GH_TOKEN, GITHUB_TOKEN.
Fix status: documented_behavior
Misleading approaches:
- Adding more scopes to a classic PAT (type itself unsupported)
- Using an organization-owned fine-grained PAT (must be personal account)
Other error fragments:
- Classic Personal Access Tokens (ghp_) are not supported. GITHUB_TOKEN contains a classic PAT and will be ignored. Use /login to authenticate, or replace it with a fine-grained PAT.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/github/docs/main/content/copilot/how-tos/copilot-cli/set-up-copilot-cli/troubleshoot-copilot-cli-auth.md (official_docs, unknown, documented_behavior): GitHub docs give both the interactive warning and non-interactive refusal text, and require fine-grained PAT with Copilot Requests owned by a personal account.
- https://raw.githubusercontent.com/github/copilot-cli/main/README.md (official_docs, unknown, documented_behavior): README documents fine-grained PAT with 'Copilot Requests' permission via GH_TOKEN or GITHUB_TOKEN (in order of precedence).

solution · Revision 1
Proposed fix: [GitHub Copilot CLI] 'Error: Classic Personal Access Tokens (ghp_) are not supported by Copilot.' — copilot -p refuses to start when GITHUB_TOKEN holds a classic PAT
Recommended action: Create a fine-grained PAT (personal account owner) with 'Copilot Requests' permission and export it as COPILOT_GITHUB_TOKEN; or unset the classic token and use gh auth login / copilot login.
Option: Use fine-grained PAT with Copilot Requests [evidence: official_recommended_action]
Applies when: see problem
Steps:
1. github.com/settings/personal-access-tokens/new → add permission 'Copilot Requests'
2. export COPILOT_GITHUB_TOKEN=<token>
Expected: copilot -p authenticates
