Every claim in this handbook carries a tag, so you can tell documentation from observation from opinion.
- DDocumented. Documented by Microsoft on Learn, Support, Message center, GitHub or an official blog, as of the dates in Appendix E
- OObserved. Observed first-hand on 7 November 2026 in a live Copilot Code cloud session: its tools, its sandbox, an example tenant's policy verdicts, and the repository of a production partner-sales app
- CCommunity. Reported by the community (MVP blogs, forums, videos, GitHub issues) and not confirmed by Microsoft
- IInference. Inference or recommendation by the author; test it before you rely on it
Part 24
Case study: four days, 53 commits, one production app
- What it isAn anonymised case study of a production partner-sales app built with Copilot Code: its numbers, how it was run and what it taught.
- What you doCopy the habits that worked: a spec per initiative, a rubric read every session, scored and logged releases, and tested read-only guards.
- Watch outVisual checks were the bottleneck, and overrides of the release bar must be logged with the evidence still owed.
The app behind most of the O evidence in this guide is a production partner-sales app: an opportunity tracker, an email workspace, customer and contact views, and a read-only view of data another team owns. It was built with Copilot Code, released from parallel sessions, and examined read-only for this guide on 7 November 2026. O

24.1By the numbers
| Measure | Value |
|---|---|
| First commit | 4 November 2026 |
| Commits by 7 November | 53 |
| Files under version control | 576, of which 477 are app source and 69 are tests, fixtures and tools |
| Bound connectors | SharePoint, Office 365 Outlook, Office 365 Users and the Work IQ Copilot MCP connector |
| Tests | 495 passing in the latest local run, plus a screen check and a release scan |
| Release bar | 90 out of 100 with hard gates (rubric version 2.1) |
| Libraries added beyond the template | None |
24.2How it was run
Each initiative had its own spec in the repository: a single-email specification with seven staged releases behind switches, and a separate plan for a combined partner view. The rubric was read at the start of every session that changed the app, every release was scored and logged, and when the agent had no browser it posted a preview checklist for the owner instead of claiming a visual check it had not done. Hard rules that had to survive across sessions, such as never writing to another team's system, were kept both in the code (as a tested read-only guard) and in saved memory. O
24.3What went right
- The old email composer is being retired in planned stages; the first stage went live with every switch off and scored 91.
- Tests and the release scan caught regressions before users did.
- The fetch-first habit found "lost" work twice, already live from another session.
- The read-only boundary with another team's system held, enforced by code and a test.
This is the app's own Work IQ pattern, the canonical copy of which sits in section 14.4.
24.4Lessons
- Visual verification was the bottleneck. Most releases lost points only on preview items because no agent browser was available; scripted Chromium screenshots and a Cowork walk-through would close most of that gap. OI
- The bar only works if overrides are visible. Two releases shipped below 90 by a logged owner override, and both are logged with the evidence still owed. O
- Direct pushes were refused in some sessions, so the one-call publish became the normal release path. O
- A layout squeeze at about 900 pixels has sat in the known-issues backlog; known issues need owners and dates like anything else. O
- The repository is approaching the size at which others have reported fetch errors; plan for it rather than discovering it during a release. OC
Part 25
What people are building
- What it isPublic builds, costs, habits, pain points and comparisons reported by the community, with each source named.
- What you doUse these reports to set expectations and budget per app, and build the data layer before the screens.
- Watch outCommunity reports are not confirmed by Microsoft, and entries marked unverified have no source link in the research.
Public evidence is still thin for the newest tools. Copilot Code began rolling out to Frontier tenants in late October, and Copilot Studio Apps coverage is mostly licensing explainers, so most hands-on reports concern Cowork's App skill and the older App Builder agent and Power Apps tools. Searches found no meaningful Reddit, Hacker News or X discussion of these products as of this edition. C
What whole-app builds have cost, against per-task planning bands
Hollow dots are community figures with no source link in the research (marked unverified in section 25.1). Budget per app, not per task.

25.2What successful builders have in common
- They build the data layer first and hand the agent an as-built schema.
- They name every list, table and site explicitly.
- After each test action they open the backing list; it shows the bug before the screen does.
- They plan first and work in passes, testing each pass before saying "Continue".
- They watch cost as they go, with /cost in Cowork.
- They keep an exit: source they can export, and data in SharePoint or Dataverse that they can open themselves.
- They test sharing with an account that doesn't own the app.
25.3Pain points people report
Re-check after Ignite
- Apps that look finished before the data actually saves.
- People pickers that don't resolve users.
- Confusion about licensing and runtime credits for the people who use the app.
- The contradiction in the documentation about whether sharing an app shares its data.
- Churn: the App Builder agent and vibe.powerapps.com retire on 30 November 2026; one-click Migrate app goes to Apps in Copilot Studio only, and moving to Cowork is a manual rebuild D; and the SDK packages are being renamed.
- CLI and SDK rough edges: an ambiguous Dataverse connector option, no agent-runtime operation for calling Copilot Studio agents, clone problems on macOS, route errors.
- No deep links into a specific record or page.
- No app events seen in the Purview audit log yet.
- Agents quietly creating mock data locally that "looks great until you realize nothing is hitting Dataverse"; ask every build summary to confirm it uses live data only. C
- Whole-app builds costing far more than per-task planning bands suggest: 669 and 5,415 credits against bands of 25 to 200-plus credits per task. C
- Testing against a separate test database isn't possible inside one app, because a managed app always uses the data source configured during development. C
25.4How people compare it
Against consumer tools such as Lovable and Bolt, the most-quoted verdict, from Daniel Anderson, is that a Copilot-built app runs inside Microsoft 365 under your own permissions, with its data in lists you can open yourself. C Lovable itself now deploys into Microsoft tenants through the Copilot Managed Runtime SDK, which makes the runtime, not the builder, the thing being compared. D Against developer agents, one commercial commentator (Ritesh Agarwal, Appycodes) argues the real advantage is work context, and the real gap is everything a business user doesn't think to specify: row access, validation, audit and rollback. C Skeptics advise treating early Copilot Studio drafts as sketches (Helen Jones, Collab365). No credible head-to-head comparisons with v0, Replit, GitHub Spark or Retool were found. C
- Against Power Apps canvas apps: "Power Apps is not dead, at least not yet," with open questions about ALM, sharing control and Dataverse security roles (Nick Doelman). Others describe managed apps as an evolution of Power Apps code apps on the Microsoft 365 side (Sean Astrakhan). C
- On governance: Copilot Managed Runtime moves governance from the build tools "to the place their code runs," with a Power Platform environment behind every app (Holger Imbery). C
- On maintenance: these are real code apps whose dependencies age, so someone has to own updates (an Ask HN thread); and "the gap is everything a business user cannot be expected to specify" (Appycodes). C
- On cost: builders now pay too, because Microsoft won't let the builder become a free model endpoint (Jukka Niiranen); and Microsoft 365 or Dynamics 365 use rights don't cover running these apps (Holger Imbery). C
Part 26
The frontier: patterns almost nobody is using yet
- What it isThirty-two app patterns built from documented or observed pieces that almost nobody uses yet, plus what isn't possible today.
- What you doPick a pattern, run the check in its last column in your tenant first, and ask for any admin exception early.
- Watch outEvery pattern needs a tenant test, and several depend on actions or connectors outside the default policy.
Every pattern below is built only from documented or observed pieces, but almost none appear in public examples yet. Each needs a tenant test, and some need an admin exception; the last column says what to check first. I
| Pattern | Building blocks | Check first |
|---|---|---|
| 1. Field inspection kit: photo, barcode, signature, PDF report | Template camera, barcode and pen controls; PDF export; a SharePoint list and library | Camera permission in the player and on phones; attachment sizes |
| 2. Asset check-in kiosk | Barcode control, a Dataverse or SharePoint table, keyboard shortcuts | How a shared device signs in |
| 3. Work IQ brief beside every record | Work IQ Copilot MCP connector, Office 365 Users, the record's list | Latency (timeouts, retries, cache) and Work IQ billing |
| 4. Draft-and-approve outreach desk | Outlook connector (draft, read back, update, send), recipient guards, an outreach log list | Send checks on every path; do-not-contact data |
| 5. Read-only cockpit over another team's system | Table-mode bindings with read-only adapters and tests | The data owner's agreement; a kill switch |
| 6. Permission-trimmed case workbench | Dataverse with security roles; SharePoint documents | Roles set before launch |
| 7. Meeting-to-commitment tracker | Outlook calendar, Planner, Teams, a SharePoint status list | Which actions are allowed |
| 8. Release readiness cockpit | Azure DevOps connector, Planner, Teams, Dataverse decisions | Azure DevOps actions allowed in the policy |
| 9. Bookings exception desk | Microsoft Bookings, Outlook, an exceptions list | Bookings operations allowed |
| 10. Policy attestation tracker | SharePoint policy files, Dataverse attestations, Outlook reminders | Server-side permissions on attestations |
| 11. Analytics with write-back | Power BI ids looked up in Code; Dataverse or SharePoint for decisions | Framing in the content security policy; Power BI licensing |
| 12. 3D product or part viewer | Template 3D viewer reading glTF or STL from SharePoint | File sizes |
| 13. Training quest or adoption game | three.js in the template, a scores list | Keyboard and screen-reader access |
| 14. Daily self-test by Cowork | A Cowork schedule plus browser use: open the play link, check totals, post results to Teams | Admin opt-in for browsing; credits |
| 15. App, agent and flow together | A Copilot Studio agent and a Power Apps-trigger flow, bound from the app | Flow binding for managed apps is undocumented; the Copilot Studio connector needs an exception |
| 16. Pilot rings for features | Feature switches read per user or group from a SharePoint config list | New code still needs a release |
| 17. Personal store per user | A JSON file in each user's OneDrive with a local cache | Merge rules across devices |
| 18. Spec-to-test traceability | Numbered DESIGN.md items mapped to tests; the release scan fails on unmapped items | Discipline |
| 19. Scripted visual regression | Chromium screenshots of every route at two widths, compared release to release | Fixture data and flaky renders |
| 20. Help desk grounded in Microsoft Learn | Microsoft Learn Docs MCP server | Public documentation only |
| 21. Fabric-backed analytics app | Fabric MCP server | Which operations your admins allow |
| 22. Bring your own build | ms CLI with --repo none and external artifacts | Off by default; you own supply-chain checks |
| 23. Goal check-in desk on Power BI scorecards | Power BI connector actions to read goals, create check-ins and add notes; no freeform queries needed | Scorecard permissions; which goal actions your policy allows |
| 24. One-click board pack | Power BI "Export To File" for a filtered report, then an Outlook draft with the PDF attached | Export needs capacity-backed workspaces; keep sending as a draft |
| 25. Refresh-after-entry | The app writes adjustments, then calls the Power BI "Refresh a dataset" action so the report catches up | Refresh limits per day on your capacity |
| 26. Agent quality console | Copilot Studio connector actions to run evaluation test sets and read test runs | Copilot Studio connector needs a runtime exception |
| 27. Cowork night shift | A Cowork scheduled prompt reads the app's list each morning, posts overdue items to Teams and drafts follow-ups for approval | Include record ids in messages, since record deep links aren't supported |
| 28. Inbox-to-app intake | A Cowork event trigger on matching mail creates a record; the managed app is the review screen | Triggered actions draft for approval by default |
| 29. Project as the app's memory | One Cowork Project holds the spec, ERD, as-built schema and instructions, which take precedence over global instructions | Files can't yet be removed from project outputs |
| 30. Release-pack skill | A custom skill that writes release notes, a training deck and an accessibility report for each version | Skill limits: 50 skills, 1 MB per SKILL.md |
| 31. 3D and maps inside the default policy | Bundle three.js locally; draw static SVG maps instead of loading tiles | Worker-based loaders and tile servers need admin-approved origins |
| 32. Fabric-backed app data | The plugin's feature-gated backend workflow stores data in Fabric so Power BI can report on it | Preview, and announced rather than shipped in Copilot |
26.1Not possible today, and what to do instead
- Offline use or an installable app: service workers are blocked by the default content security policy. D
- Direct calls to arbitrary web APIs: they need an admin-approved origin, and "Send an HTTP request" actions are blocked by default. D
- Deep links into a specific record or page: not supported yet; show a recent-items list on the home screen. C
- A dev, test and production pipeline for one app: only preview and live exist; use feature switches or a second app for user testing. DI
- Microsoft Graph from app code: no token path is documented; use connectors. DI
- Embedding the app in Teams or SharePoint: not documented for managed apps, and framing needs admin changes to the content security policy. D
Guest and partner access is the most common request on this list, so the alternatives are spelled out here.
Part 27
Troubleshooting and known limits
- What it isCommon symptoms, their likely causes and fixes, and the known limits of this edition.
- What you doFind the symptom in the table, apply the fix, and read the related part for detail before you escalate.
- Watch outSome causes come from community reports, so read the evidence tag before you treat a fix as settled.
| Symptom | Likely cause | Fix |
|---|---|---|
| The app looks done but nothing saves | The source was never bound, so screens run on sample data | Ask which screens use sample data, bind the source by its exact name, then check the list after a test save |
| A connector shows as allowed but calls fail with 403 | Runtime connector policy, a blocked action, or mixed connector policy and DLP | Check the environment group's connector rule and the action toggles with your admin |
| Something silently doesn't load | The content security policy blocked it | Read the browser console's CSP message and ask for one narrow origin to be added |
| Users see a consent prompt or "connection needed" | First open, or an expired connection | Approve once; owners check connection status before releases |
| A user can't open a shared app | Not in the environment security group, a guest, or no license or credits | Check the group, the user type and the spending policy |
| Users are blocked after a few minutes | No Power Apps Premium and no runtime credits | Assign Premium or add them to a managed-applications spending policy |
| The live app doesn't show the change | Built or pushed but not deployed, or an older commit deployed | Deploy the remote tip and confirm on the live link |
| A deploy shipped an older version | The latest build failed and the deploy fell back to the last good build | Read the build log, fix, redeploy the intended commit |
| git push refused as "disabled" | The session blocks direct pushes | Use the one-call publish, which pushes, builds and deploys |
| Fetch fails with an I/O or write error | Workspace file system or repository size | Retry with core.logAllRefUpdates turned off; keep an eye on the object count |
| Environment setup in progress | Your developer environment is being created on first use | Wait about two minutes and retry |
| A tester can't open the preview | The preview needs repository write access | Test on live behind a feature switch, or give edit access only to co-owners |
| A Work IQ panel spins forever | Long-running calls or throttling | A three-minute timeout, one retry on 429 or 5xx, a per-user cache and a visible error |
| A Dataverse table can't be found | Personal developer environments start without Dataverse | Add Dataverse to the environment in the Power Platform admin center |
| Excel data stops at 256 rows | The connector's default page size | Page through results, or move the data to a list or table |
| You can't link to a specific record | Deep links aren't supported yet | Link to the app and show recent items on the home screen |
| Two sessions keep undoing each other | No locking, overlapping scopes | One scope per session; fetch and rebase; handoff notes |
| A method you expected is missing from generated/ | Policy filtered the operation out before code generation | Check the connector's action-level policy; ask for an exception (section 16.7) or use another action |
| Works in the local loop, fails after publishing | A Conditional Access challenge or consent the hosted app hasn't got | Test the published preview with an ordinary user; read the status code and response body together |
| Only some recipients were shared | Unresolved email addresses are skipped with a warning | Re-run with object ids and check ms app share list --access play |
| The SharePoint binding is refused | Root site, OneDrive or an unusual site URL | Move the list to a plainly named site under /sites/ or /teams/ |
| The app can't call a Power Automate flow | The Logic flows connector is blocked or not on the runtime allow-list | Have the app write a record that triggers the flow instead (Part 13) |
| The play link shows RouteNotFound but the preview link works | An open platform issue reported in some regions | Test with the preview link and report the app id on the GitHub repository C |
| Power BI "Run a query" isn't generated or is reported as blocked | The default runtime policy blocks freeform queries | An admin allows that action in the environment group's policy, or use another pattern (Part 12) CD |
| The admin center says no connectors are allowed | An older environment group without an advanced connector policy | Check the group's connector policy and data policies in the Power Platform admin center D |
| ms app clone fails on a Mac | A reported libcurl problem | Clone on Windows or Linux until it's fixed C |
| A Copilot Studio agent can't be called from the app | Only standard agents are callable; agents on the GitHub Copilot harness aren't yet | Use a standard agent for app calls C |
| SQL actions return 404 | A routing bug in an older SDK | Upgrade the SDK; table-mode reads were unaffected C |
| The Code tab doesn't appear in the Windows app | Code on the desktop needs the unified Copilot app, the right channel and, for local sessions, an admin opt-in | Use the web at copilot.cloud.microsoft for cloud sessions, and ask your admin about desktop access (Part 3) D |
| Cowork can't bind to an existing SharePoint site | A Graph permission error that needed an admin | Ask an admin before a demo, or use a site you own C |

Part 28
Templates you can copy
- What it isTemplates to copy: prompts, DESIGN.md and QUALITY-RUBRIC.md skeletons, a release log entry, checklists, a list specification, an exception request and an announcement.
- What you doCopy the templates into your repository on day zero and replace the placeholders with your app's details.
- Watch outA template helps only if every session reads it, so keep the prompts and rubric in step with your own files.
- 28.1
Kickoff prompt
Plan only; don't build yet. We are creating [app name] for [users] so they can [outcome], and we will know it works when [measure]. Data: [system of record with exact site, list or table names]. These sources are read-only and must never be written to: [list]. Create README.md, DESIGN.md (numbered, testable items; data contract; navigation rules: every screen names itself and has a one-click Back link; out of scope), DECISIONS.md, QUALITY-RUBRIC.md (release only at 90 of 100 with hard gates), RELEASE-LOG.md, HANDOFF.md and src/features.ts. List which screens will run on sample data and why. Ask me what you need as multiple-choice questions, then show me the plan.
This is the same kickoff prompt as section 18.4, with both read-only and rubric rules restored.
- 28.2
Session-start prompt
Fetch the app and compare with the remote main. Read DESIGN.md, QUALITY-RUBRIC.md, RELEASE-LOG.md and HANDOFF.md. Tell me what is live, what is committed but not released, what is in progress in other sessions, and the next step. Don't change anything yet.
- 28.3
Release prompt
Release this change. Run the machine checks and show the output. Render the changed screens at 1280 and 390 pixels and show me the screenshots. Score it against QUALITY-RUBRIC.md with evidence for every item. If it is 90 or more with every gate passed, pull with rebase, publish, confirm that the live app holds the change, and log the scorecard. If not, list the missing points and how to earn them, and stop.

Appendices
- What it isReference material: the ms CLI, the admin settings map, where sources disagree, a glossary and the sources used.
- What you doUse Appendix B to find a switch, and Appendix C to decide what to do when sources conflict.
- Watch outAdmin paths and package names move often, so search the admin center for the setting name if a path has changed.
- Appendix A
ms CLI quick reference
The CLI is published as @microsoft/managed-apps-cli and invoked as ms; Learn still documents it under that name, while the new GitHub repository lists @microsoft/cmr-cli. It needs a recent Node LTS, Git and Git Credential Manager, and every command accepts --json, --non-interactive, --no-color and --cloud. DC
