AI agent · GitHub Issue to release

From a GitHub Issue to a tagged release

Q: Which models can Orbi use?

Pi can use an OpenAI-compatible API or a Codex subscription. Claude Code is not supported.

The endpoint is a tagged release, not a pull request. Label one concrete Issue ai-ready; Orbi writes the code, opens a PR, runs an independent review, merges only the reviewed head, then tags and publishes the GitHub Release for the milestone.

THE DELIVERY LINE

Six steps from Issue to release

This is the GitHub-native workflow described in the Orbi workflow.

01 · LABEL
Mark the Issue ai-ready
The label puts one Issue into the delivery queue.
02 · IMPLEMENT
Claim it and implement in an isolated worktree
Orbi takes the Issue and writes the change away from the shared checkout.
03 · OPEN A PR
Open the pull request
The implementation becomes a normal GitHub PR with its evidence.
04 · REVIEW
Independently review the Issue’s acceptance criteria
A separate review session can repair the branch and rerun tests.
05 · MERGE GATE
Merge only when CI is green, the head is unchanged, and the base is current
The gate protects the exact reviewed head.
06 · RELEASE
Tag and publish a Release by milestone
The release flow turns the completed milestone into a tagged GitHub Release.

PUBLIC EVIDENCE

A real Issue became a reviewed change

See the public evidence page for Issue #1328, its Issue, and the resulting PR #1331.

START WITH A GOOD CONTRACT

Write an ai-ready Issue

Describe one runtime outcome and acceptance criteria someone can check. Avoid a project plan or a pile of unrelated wishes: the Issue is the contract the implementation and independent review use. The 12 factors for an ai-ready Issue show what to include.

If the result cannot be checked, Orbi cannot safely decide whether it is done.
