Mira's first responses to new PRs and issues now post without a card, once the gateway's checks pass. A redraft of an open comment replaces it, so a comment can no longer be approved and posted twice.

In the first two weeks there were 105 comment cards. Most rejections came in the first week, and most were about closing rather than welcoming. Closures still need approval. In the second week, review caught one unfinished draft and let through three pairs of duplicate comments (template-playground#1105, template-playground#1106, concerto-codegen#315).

Changes

• New action kind github.first_response, set to auto. The gateway posts it at once if:

  • the PR or issue is open, and the network has no earlier approved or posted comment there;
  • the text is at least 80 characters, has no draft markers and doesn't end mid-sentence;
  • it @mentions no one but the author, and says nothing about the network.

  Otherwise it refuses, and Mira redrafts. It still comes as a card when Mira rates it high risk or a member set the work going.

• The gateway signs these comments as posted automatically, and strips the draft's "reviewed by a maintainer" label.

• A new github.comment or github.first_response from the same agent on the same target lapses the older open one.

• issueState now also returns the author, so the mention check knows who it may allow.

• Updated: Mira's spec (triage step 1), the public-voice rule in _protocol.md, rule 3 in CLAUDE.md, and decision 78.

Safety

Adds an auto action kind (rule 3), as the owner decided. Comments that close or reply to an issue stay github.comment, which needs approval. Setting auto: false on github.first_response makes every first response a card again.

Deploy

npm run gateway:deploy and npm run deploy:agents (the deploy workflow does both).
