Email

claudex:email — broadcast a brainstorm question to your panel

Send-only. Emails the current question + a short context snapshot to a panel defined in ~/.claude/claudex/panel.json, so people can read it on their own device during a screen-shared meeting and respond by email or aloud. It does NOT collect, match, or summarize replies, and does NOT change claudex:think.

Canonical invocation: /claudex:email [filter]. Replies land in the connected Gmail account and are not monitored live.

Step 1 — Parse panel (true fail-fast)

Read ~/.claude/claudex/panel.json. If it is missing or does not parse, STOP and tell the host to create/fix it. Recipients are parsed from data.panel.members; the members array is nested under the top-level panel key. Minimal required shape:

{
  "panel": {
    "members": [
      { "name": "Name", "email": "[email protected]", "role": "student", "include": true }
    ]
  }
}

If panel.members is missing or is not an array, treat it as a panel schema error and STOP before drafting. This is the only hard stop before drafting — everything else still produces a draft you can fall back to.

Step 2 — Resolve recipients

Resolve recipients only from data.panel.members plus any validated ad-hoc email tokens.

• No argument: every member with include: true.
• Argument contains a token with @: strip surrounding angle brackets, commas, semicolons, and whitespace from each such token; lowercase the domain; then validate it against a conservative email regex such as ^[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,}$. If any @ token is not a valid email, STOP and list the rejected tokens. Valid ad-hoc emails are combined with any other (non-@) filter tokens.
• Other tokens (case-insensitive):
  • professor/professors → role: professor; student/students → role: student.
  • Name tokens (e.g. florescu bozdog) match against name. Multiple tokens are OR — florescu bozdog resolves to BOTH people, not one person matching both.
• NEVER select a member with include: false unless explicitly named in the argument.
• Each selected member from panel.members must have non-empty string name, email, and role fields plus a boolean include field. If any selected member fails this validation, STOP. If any selected member lacks a valid email, show which selected member is invalid.
• Deduplicate the final recipient list by normalized lowercased email before preview, send, and log. Show the unique recipient count.
• If zero recipients resolve, STOP and show what matched / was excluded.

Step 3 — Assemble the draft (always, even if Gmail later turns out unavailable)

Current-question rule (strict): ignore the /claudex:email invocation text itself and any confirmation prompts. Use the most recent ASSISTANT-posed brainstorm question shown to the host plus a 2–4 line summary of the immediate discussion. If there has been a topic shift, there is no active brainstorm question, or there is any doubt, STOP and ask the host to paste the exact question. Do not guess.

Allowlist (authoritative): the subject, the body, the preview, and the logged question may contain ONLY the current question text plus the short context snapshot. Include nothing else from panel.json beyond actual recipient addresses (no meeting.*, no member title/expertise, no member emails outside the final recipient addresses), and no tool output, hidden reasoning, implementation/planning notes, local file paths, or credentials. Sanitize the logged question the same way as the email draft.

• Subject: [S.A.G.E.] <short question> — single line, ≤ 80 chars, no newlines.
• Body (plain text, target ≤ ~250 words):
  1. Identification line: "This is Hao Fu's brainstorm assistant for the S.A.G.E. meeting — sending the question we're on so you can follow along."
  2. Where we are: 2–4 line snapshot.
  3. Question: the current question + its options if multiple-choice.
  4. Closing: "Reply here or raise it on the call."

Step 4 — Gmail availability check

After the draft exists, confirm a Gmail send tool (e.g. mcp__gmail__send_email) is available, and ensure ~/.claude/claudex/state/ exists (mkdir -p). If creating the state directory fails, continue to preview/send but warn "logging may fail".

If the email cannot be sent for any reason — tool unavailable, send fails, or send hangs — present the fully-assembled draft (recipients, subject, body) under a "Manual send fallback" heading and STOP.

Step 5 — Preview & confirm (required)

If a Gmail account/profile identity tool is available, look up and display the actual connected sender address in the preview. Otherwise show "the connected Gmail account (confirm it is the intended sender)". The expected account for this setup may be [email protected], but never state it as verified fact without checking.

Show the host: recipients as a list with the unique recipient count + class (e.g. "7 unique included panel members" or "2 unique professors (Florescu, Bozdog)"); the line "All recipients are in To: and will see each other."; the connected Gmail account wording above; and the exact subject + full body. Then ask a count-based confirm: "Send to N <class> from the connected Gmail account?" Proceed only on an unambiguous affirmative. If the host's reply adds conditions (for example, "yes, students only"), re-resolve recipients and re-preview before sending. Declining aborts with no send and no state write (the dry-run path).

Step 6 — Send

Call the Gmail send tool once with all unique recipients in to, the subject, and the body. If the send fails or hangs, follow the Manual send fallback rule in Step 4.

Step 7 — Record

Append one line to ~/.claude/claudex/state/panel-sends.jsonl. Log recipients as the array of normalized email addresses, never display text like "7 included members". Set sentId from the send result (result.id, else the stringified returned identifier), and include threadId if the send result contains one:

{"ts":"<ISO8601>","sentId":"<result.id or stringified returned identifier>","threadId":"<thread id if returned>","subject":"<subject>","question":"<sanitized question text>","recipients":["a@x","b@y"]}

If this append fails AFTER a successful send, report "Sent but not recorded" with the subject and the returned id — not an outright failure.

Step 8 — Report

Report Sent (plain ASCII, no emoji) and the returned id. Remind the host replies arrive in the connected Gmail account and are not monitored live.

Hard rules

1. Send-only. Never poll, match, or summarize replies here.
2. Always preview + confirm before sending to real people.
3. Never leak: follow the Step 3 allowlist for subject, body, preview, and log.
4. Never touch claudex:think or its gate.
