Axon Triage Report

Kind: kind/feature

Status: STILL VALID

Evidence:

• No references to "cubic-dev-ai" exist anywhere in the current codebase (source files, CI workflows, configs).
• This appears to refer to a third-party GitHub App installed on the axon-core organization, used for some external automation purpose, which the issue author wants to replace with axon's own self-development capabilities.
• The project already has a mature self-development pattern (self-development/ directory) with TaskSpawners for issue triage, worker tasks, fake-user testing, and strategist exploration. These could potentially serve as the replacement.
• No merged PRs or commits reference this issue or the removal/replacement of the cubic-dev-ai app.
• The issue is actionable: it requires identifying what cubic-dev-ai currently does for the organization and migrating that functionality to axon's own TaskSpawner/self-development infrastructure.

Duplicates found: None found. #27 (Self Development) is a broader parent issue about axon developing itself, but it does not specifically address replacing the cubic-dev-ai app.

Recommendation: KEEP OPEN — The cubic-dev-ai app has not been replaced yet. The issue would benefit from additional context about what specific functions cubic-dev-ai currently performs, so the replacement scope is clear.
