PRD: AI Meeting Summaries — Decisions & Action Items
Sep 24, 2026 · @Martin Slaney
Summary
We will generate a summary after every recorded Huddle meeting that lists the decisions made and the action items, each with an owner who was verifiably in the meeting. The organizer reviews the summary and sends it in one click; nothing is emailed without that step in v1.
Problem. Today attendees write their own notes after the call. Notes are inconsistent, often missing, and action items lose their owners within a day. We already have what we need to fix this: a recording, a transcript with speaker labels, and the calendar attendee list.
Why this is not trivial. Two of those inputs are unreliable. Speaker labels are wrong about 8% of the time, mostly during crosstalk and when several people share a meeting-room device. About 15% of meetings include someone who joined without a calendar invite. A naive build would misassign owners often enough to lose trust in the first week.
Goals and metrics
The goal is summaries people send without rewriting, with zero actions assigned to non-attendees.
Goals
- Replace manual post-meeting notes for recorded meetings.
- Every action item has a correct owner or is explicitly marked unassigned.
- Get action items to owners within minutes of the meeting ending.
Non-goals (v1)
- Pushing tasks into Jira, Asana or Linear.
- Summaries for unrecorded meetings or live, in-call summaries.
- Improving diarization itself. We design around the 8% error rate, not fix it.
Success metrics
| Metric | Target | Type |
|---|---|---|
| Actions assigned to someone not in the meeting | 0 | Hard constraint, blocks release |
| Owner precision on items sent with an owner | ≥ 97% | Quality |
| Summaries sent within 30 min of meeting end | ≥ 60% of recorded meetings | Adoption |
| Summaries sent with no edits | ≥ 50% | Quality |
| Owner reassignments per sent summary | ≤ 0.3 | Quality |
Owner precision is measured from organizer edits plus a weekly labelled sample of 200 meetings.
Users and core flow
The organizer owns the summary; attendees receive it.
- Organizer: reviews, fixes owners, sends. Usually the calendar invite's creator; can hand off to any attendee.
- Action owner: receives their items by email and in the app.
- Other attendees: receive the full summary once sent.

The roster filter runs as deterministic code after the model, never inside the prompt alone.2 Target: summary ready for review within 5 minutes of meeting end for meetings up to 90 minutes.
Requirements
An owner can only be chosen from the verified roster: people who actually joined, not people who were invited.
Verified roster
1. R1. Build the roster from the join log, not the calendar invite.1 Invited people who never joined are excluded. 2. R2. Each roster entry has an identity tier: - Verified: joined signed in to a Huddle account, or by a dial-in matched to a known number. - Guest: joined with a display name only (most of the 15% uninvited joiners). - Room: a meeting-room device; people behind it are unknown individuals. 3. R3. Match uninvited joiners to workspace accounts by signed-in account only. Never match on display name alone.
Summary content
- R4. Decisions: a short statement of each decision, with a transcript timestamp link. No owner field.
- R5. Action items: task, owner (or "Unassigned"), due date if said aloud, timestamp link, and confidence.
- R6. Every item links to its evidence in the transcript so reviewers can check it in one click.
Assignment rules
- R7. The model returns a proposed owner per item. Code then checks it against the roster. Any owner not on the roster is replaced with "Unassigned", and the named person is shown as a mention ("mentions: Dave, not in meeting").
- R8. Owner comes from content first: a named request ("Priya, can you…") beats the speaker label of "I'll do it".
- R9. Mark an owner low confidence when the evidence depends on a speaker label in an overlapping segment, a Room entry, or a Guest entry.
- R10. Low-confidence items show as "Suggested: Priya" and need organizer confirmation before any email goes out.
- R11. Room and Guest entries cannot receive email. The organizer can reassign to a verified person or leave it unassigned.
- R12. Log every model proposal, filter result and organizer edit. This is our precision measurement.
Handling the known limits
Both limits hit ownership, not decisions, so we contain them at the owner step.
| Limit | What goes wrong | How we handle it |
|---|---|---|
| Speaker labels wrong \~8% (crosstalk) | "I'll take that" credited to the wrong person | Content-first owner rule (R8); overlap segments flagged low confidence (R9) |
| Speaker labels wrong \~8% (shared room) | One label covers several people | Room tier; items resolved to a room need a named person or stay unassigned (R11) |
| \~15% of meetings have uninvited joiners | Real participant missing from roster, or matched to the wrong account | Roster from join log (R1); account match only (R3); Guests can own items but get no email |
| Invited but absent | Model assigns to a name from the invite | Excluded from roster; hard filter (R7) |
The error compounds per meeting. If each item's owner is wrong 8% of the time, a meeting with 5 action items has a 34% chance of at least one wrong owner (1 − 0.92⁵). That is why confirmation sits before email, not after.
Sales request: auto-email on meeting end
Decision: not in v1 as requested. We ship one-click organizer send now, and gated auto-send in phase 2 once measured precision earns it.
Why not now. An email to the wrong owner is the most visible failure this feature can have. With the error rate above, roughly a third of 5-item meetings would email someone a task that isn't theirs. With external guests, it may land outside the customer's company. Early trust is hard to win back.
What Sales gets instead.
- v1: the organizer gets a "Summary ready" notification within 5 minutes and sends with one click. Goal: sent within 30 minutes (see metrics).
- Phase 2: a workspace setting to auto-send at meeting end, but only items that are high confidence and owned by a Verified attendee. Everything else still waits for the organizer. It ships only when owner precision on high-confidence items is ≥ 97% for 4 consecutive weeks.
- Auto-send never emails Guest or Room entries, or anyone outside the customer's domain, unless an admin enables it.
Design notes
The review screen must make checking owners faster than writing notes.
- Decisions first, then action items grouped by owner, then Unassigned.
- Low-confidence owners look visibly different ("Suggested") and are editable inline from a roster picker, never free text.
- Each item plays its transcript clip on click.
- The Send button states who gets email: "Send to 4 owners and 7 attendees".
- Empty state: if no decisions or actions are found, say so plainly rather than inventing any.
Rollout
| Phase | Scope | Exit criteria |
|---|---|---|
| Internal | Huddle's own meetings | Zero non-attendee assignments; precision logged |
| Beta | 50 opted-in companies | ≥ 97% owner precision on sent items; ≥ 40% sent within 30 min |
| GA | All 3,000 companies, organizer send | Beta targets held for 4 weeks |
| Phase 2 | Gated auto-send setting | See Sales section |
Open questions
- [ ] Is the join log's signed-in identity reliable enough to call "Verified"? Engineering to confirm.
- [ ] Who organizes when the invite creator didn't attend? Proposed: first Verified attendee from the invite.
- [ ] Do customers need to disable summaries per meeting for sensitive calls? Legal and Sales to confirm.
- [ ] Retention: how long do we keep drafts and the evidence log?
What a PM had to fix
1Invented evidenceVerify or remove the claimTargeted repair
Source: Scenario
the attendee list comes from the calendar invite
What we’d changeTreat the join log as a dependency to confirm, not an input that exists today. Say what proves attendance, and don't promise zero non-attendee assignments until that's settled.
2Constraint missedRestore the constraintTargeted repair
Source: Constraint
Summaries must never assign an action to someone who was not in the meeting.
What we’d changeApply the roster check to organiser edits and the final send as well, not only to the model's output.

Got wrong · 3
- Uses the supplied evidence correctlyThe output claims that today's notes are inconsistent, often missing, and action items lose owners within a day; this is not in the supplied context and invents current performance.
- Avoids unsupported claimsThe statement about notes being inconsistent and action items losing owners is presented as fact without the supplied evidence supporting it.
- Proposes tests that could failInternal and beta exit criteria lack a measurement window (beta has no duration, internal only 'zero non‑attendee assignments' without a window), and not all phases state the action each result triggers.
Mixed · 1
- Success settles trade-offsSuccess metrics lack a time frame, and no explicit trade-off rule is stated beyond the hard constraint, so the PRD does not define which goal wins when two conflict.The two graders disagreed on this one.
Got right · 5
- Addresses the actual decisionIt commits early to organizer-reviewed summaries with no auto-email in v1, says what would change that (precision data), and frames the choice for engineering and design leads.
- Respects explicit constraintsThe PRD enforces the zero-non-attendee constraint with a verified roster and hard filter, and the output is within the 1,000–1,500 word aim.
- Identifies material uncertaintyIt names specific unknowns (join log reliability, organizer when creator absent, per-meeting disable, retention) and how they would be resolved.
- Produces the required deliverableThe output is a PRD that gives requirements, flow, design notes, and rollout; engineering and design leads could start work from it with light edits.
- Specifies AI failure behaviourIt specifies low‑confidence flags, unassigned fallback, and organizer confirmation before email, covering AI uncertainty and errors.
Claims the judge couldn’t find in the brief
