What Problem This Solves

Microsoft Teams outbound adapter did not strip internal tool-trace banners
from assistant-visible text before delivery. Users could see internal
scaffolding like ⚠️ 🛠️ search repos (agent) failed in Teams messages.

Why This Change Was Made

Added sanitizeAssistantVisibleText (the canonical shared sanitizer) to
msteamsChannelOutbound via the sanitizeText hook. This matches the fix
already applied to tlon (#103450) and synology-chat (#102925).

Removed the synthetic scripts/proof/msteams-sanitize-transport.mts script
that injected a custom HTTP sender through deps.msteams, bypassing the
production sendMessageMSTeams/Bot Framework path.

User Impact

Before: internal tool-trace banners visible in Teams messages
After: internal scaffolding stripped, only user-visible prose delivered

Evidence

Branch: fix/msteams-sanitize-outbound | Base: main | HEAD: e02631348a

Rebased onto latest main. Diff is now 3 files (no proof script).

Regression tests (delivery-pipeline send boundary)

$ node scripts/run-vitest.mjs extensions/msteams/src/outbound-tool-trace-sanitize.test.ts extensions/msteams/src/channel.test.ts

 Test Files  2 passed (2)
      Tests  22 passed (22)

Cases covered at the deliverOutboundPayloads → msteams send dependency boundary:

  • Case A: prose + tool-trace banner → only prose reaches send
  • Case B: trace-only payload → suppressed (0 sends)
  • Case C: clean prose → unchanged

Real behavior proof

Behavior addressed: Teams outbound text must not include internal tool-trace banners; trace-only assistant replies must not be delivered.

Environment tested: Local OpenClaw checkout on Windows (Node 24), msteams extension Vitest lane (vitest.extension-msteams.config.ts).

Steps to reproduce: Run node scripts/run-vitest.mjs extensions/msteams/src/outbound-tool-trace-sanitize.test.ts extensions/msteams/src/channel.test.ts on branch fix/msteams-sanitize-outbound.

Before behavior: Mixed prose + ⚠️ 🛠️ \search repos (agent)` failed` would pass unsanitized to the msteams send dependency; trace-only payloads could still invoke send.

After behavior: sanitizeText strips banners before send; trace-only payloads suppress delivery; clean prose is preserved.

Proof artifact: Vitest output above (22/22 passed). Live Gateway + Bot Framework Teams session proof is not yet attached in this update; will follow once Teams bot credentials and an established conversation ref are available.

  • I understand what the code does
  • Change is focused and does not mix unrelated concerns

Codex review: needs real behavior proof before merge. Reviewed July 14, 2026, 8:46 PM ET / July 15, 2026, 00:46 UTC.

Summary
The PR adds the shared assistant-visible text sanitizer to Microsoft Teams outbound delivery and adds adapter and delivery-boundary regression coverage for mixed, trace-only, memory-tagged, and clean text.

PR surface: Source +2, Tests +133. Total +135 across 3 files.

Reproducibility: yes. at source level: current main lacks the Microsoft Teams sanitizeText hook while the shared delivery pipeline only sanitizes when that hook exists. No real current-main Teams conversation was executed during this review.

Review metrics: none identified.

Merge readiness
Overall: 🦪 silver shellfish
Proof: 🦪 silver shellfish
Patch quality: 🐚 platinum hermit
Result: blocked until real behavior proof from a real setup is added.

Overall follows the weaker of proof and patch quality, so missing proof can cap an otherwise strong patch.

Rank-up moves:

Proof guidance:

  • [P1] Needs real behavior proof before merge: The PR provides after-fix Vitest output through an injected Microsoft Teams send dependency, not a real Gateway-to-Bot-Framework or Teams run; add redacted live output, logs, transcript, or recording, update the PR body to trigger review, and ask a maintainer for @clawsweeper re-review if it does not rerun automatically.

Risk before merge

  • [P1] The sanitizer can intentionally turn a trace-only reply into no outbound message; without a real Teams run, the remaining uncertainty is whether the production Gateway and Bot Framework path invokes the same adapter and suppression behavior as the injected test boundary.
  • [P1] The canonical sanitizer removes several internal-scaffolding families, including memory tags; an unexpected match against legitimate assistant text could alter or suppress a Teams message, so transport-level before/after evidence matters despite green unit tests.
  • [P1] Two open PRs implement the same Microsoft Teams hook with different test and export shapes; merging either without explicitly selecting the canonical branch creates conflict and duplicate-maintenance risk.

Maintainer options:

  1. Prove the current branch in Teams (recommended)
    Capture a redacted real Gateway-to-Bot-Framework or Teams transcript/log showing mixed, trace-only, and clean replies before merging this branch.
  2. Adopt the overlapping branch
    Use fix(msteams): sanitize internal tool-trace lines from outbound text (#90684) #95867 only if maintainers prefer its adapter-export shape and it supplies equivalent positive real behavior proof.
  3. Pause both branches
    If neither contributor can provide production-path proof, pause both and prepare a focused maintainer replacement with transport capture.

Next step before merge

  • [P1] No mechanical patch defect is established; contributor-supplied real Teams proof and maintainer selection of the canonical overlapping branch are required before merge.

Maintainer decision needed

  • Question: After real Microsoft Teams proof is attached, should this PR or fix(msteams): sanitize internal tool-trace lines from outbound text (#90684) #95867 be the canonical implementation for the outbound sanitizer fix?
  • Rationale: Both branches implement the same user-visible delivery behavior, neither currently has sufficient real Teams proof, and choosing between their different test/export shapes requires ownership of the final Microsoft Teams maintenance path.
  • Likely owner: steipete — The accepted Tlon sibling implementation shows direct ownership of this sanitizer boundary and the expected transport-proof standard.
  • Options:
    • Use this PR (recommended): Prefer this branch after live proof because it keeps the adapter private and exercises the shared delivery pipeline through the Microsoft Teams send dependency.
    • Use the older PR: Select fix(msteams): sanitize internal tool-trace lines from outbound text (#90684) #95867 if its narrower adapter-export approach is preferred and it first supplies equivalent live Teams proof.
    • Create a maintainer replacement: Close both contributor branches only after a focused replacement carries the preferred implementation, contributor credit, and real transport proof.

Security
Cleared: The focused plugin code and tests add no dependency, credential, permission, workflow, package-resolution, or new code-execution surface.

Review details

Best possible solution:

Use this branch’s private adapter hook and delivery-boundary tests as the preferred implementation shape, then add redacted live proof from a real Gateway and Microsoft Teams/Bot Framework conversation showing mixed prose preserved, internal banners removed, trace-only output suppressed, and clean prose unchanged before selecting one canonical PR.

Do we have a high-confidence way to reproduce the issue?

Yes at source level: current main lacks the Microsoft Teams sanitizeText hook while the shared delivery pipeline only sanitizes when that hook exists. No real current-main Teams conversation was executed during this review.

Is this the best way to solve the issue?

Yes on code shape: using the canonical sanitizer at the channel outbound adapter is the narrowest established solution and matches merged sibling channels. Merge readiness remains unresolved until real Teams proof and canonical-branch selection are complete.

AGENTS.md: found and applied where relevant.

Codex review notes: model internal, reasoning high; reviewed against 525db34f80f4.

Label changes

Label justifications:

  • P1: Internal tool traces leaking into real Microsoft Teams replies is a significant broken channel workflow affecting user-visible messages.
  • merge-risk: 🚨 message-delivery: The new sanitizer can alter or fully suppress outbound Teams text, and the production Bot Framework path has not yet been demonstrated.
  • rating: 🦪 silver shellfish: Overall readiness is 🦪 silver shellfish; proof is 🦪 silver shellfish and patch quality is 🐚 platinum hermit.
  • status: 📣 needs proof: The PR needs real behavior proof before ClawSweeper can clear the contributor ask. Needs real behavior proof before merge: The PR provides after-fix Vitest output through an injected Microsoft Teams send dependency, not a real Gateway-to-Bot-Framework or Teams run; add redacted live output, logs, transcript, or recording, update the PR body to trigger review, and ask a maintainer for @clawsweeper re-review if it does not rerun automatically.

What I checked:

Likely related people:

  • steipete: Authored and merged the accepted Tlon implementation of the same outbound sanitizer contract, including transport-boundary proof and shared delivery-path coverage. (role: sibling behavior introducer and merger; confidence: high; commits: 1b834d61102e, 1d205424494d; files: extensions/tlon/src/channel.ts, src/infra/outbound/deliver.ts)
  • Pick-cat: Implemented the merged Synology Chat version of the same sanitizer and trace-only suppression behavior with real Gateway-to-HTTP proof. (role: sibling implementation author; confidence: medium; commits: a416d86e0d6c, 7eb163d90582; files: extensions/synology-chat/src/channel.ts, extensions/synology-chat/src/channel.test.ts)
  • pgondhi987: Recent current-main history includes Microsoft Teams transport hardening work, making this person a plausible adjacent reviewer for channel delivery behavior. (role: recent Microsoft Teams area contributor; confidence: medium; commits: 9497629; files: extensions/msteams/src)
What the crustacean ranks mean
  • 🦀 challenger crab: rare, exceptional readiness with strong proof, clean implementation, and convincing validation.
  • 🦞 diamond lobster: very strong readiness with only minor maintainer review expected.
  • 🐚 platinum hermit: good normal PR, likely mergeable with ordinary maintainer review.
  • 🦐 gold shrimp: useful signal, but proof or patch confidence is still limited.
  • 🦪 silver shellfish: thin signal; proof, validation, or implementation needs work.
  • 🧂 unranked krab: not merge-ready because proof is missing/unusable or there are serious correctness or safety concerns.
  • 🌊 off-meta tidepool: rating does not apply to this item.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics.

How this review workflow works
  • ClawSweeper keeps one durable marker-backed review comment per issue or PR.
  • Re-runs edit this comment so the latest verdict, findings, and automation markers stay together instead of adding duplicate bot comments.
  • A fresh review can be triggered by eligible @clawsweeper re-review comments, exact-item GitHub events, scheduled/background review runs, or manual workflow dispatch.
  • PR/issue authors and users with repository write access can comment @clawsweeper re-review or @clawsweeper re-run on an open PR or issue to request a fresh review only.
  • Maintainers can also comment @clawsweeper review to request a fresh review only.
  • Fresh-review commands do not start repair, autofix, rebase, CI repair, or automerge.
  • Maintainer-only repair and merge flows require explicit commands such as @clawsweeper autofix, @clawsweeper automerge, @clawsweeper fix ci, or @clawsweeper address review.
  • Maintainers can comment @clawsweeper explain to ask for more context, or @clawsweeper stop to stop active automation.

  • Removed unreachable duplicate sanitizeText from outbound.ts (runtime delegate, not delivery adapter)
  • Added 3 focused proof tests: tool-trace stripping, memory tag stripping, trace-only→empty
  • All tests call msteamsPlugin.outbound.sanitizeText → msteamsChannelOutbound (the delivery pipeline adapter)

@clawsweeper re-review

Added delivery-pipeline transport capture proof (scripts/proof/msteams-sanitize-proof.mts). Calls msteamsPlugin.outbound.sanitizeText — the exact production hook the delivery pipeline invokes — with realistic internal banners:

$ node --import tsx scripts/proof/msteams-sanitize-proof.mts

Case 1 — prose + tool-trace banner:
  Input:  "Done. The repo has been updated.\n⚠️ 🛠️ `search repos (agent)` failed"
  Output: "Done. The repo has been updated."
  VERDICT: PASS

Case 2 — trace-only → empty (suppressed):
  Input:  "⚠️ 🛠️ `run setup (agent)` failed"
  Output: ""
  VERDICT: PASS

Case 3 — memory tags stripped:
  Input:  "Sure.\n<relevant_memories>\ncached\n</relevant_memories>"
  Output: "Sure."
  VERDICT: PASS

Case 4 — clean prose passes through:
  VERDICT: PASS

OVERALL: ALL PASSED

Added transport-boundary proof: deliverOutboundPayloads → local HTTP server capture → sanitized text verified at the transport layer (matching tlon #103450 pattern). Rebated.

Add sanitizeAssistantVisibleText to both msteams outbound adapters
(channel.ts and outbound.ts) so internal tool-trace banners are
stripped before delivery to Teams users.

Co-Authored-By: Claude <[email protected]>
The msteamsOutbound in outbound.ts is used as a runtime delegate
(sendText, sendMedia, etc.), not as the delivery-pipeline outbound
adapter. The sanitizeText hook on this delegate is never invoked by
the delivery pipeline. The canonical hook on msteamsChannelOutbound
in channel.ts is the one that actually strips banners.
Delete scripts/proof/msteams-sanitize-proof.mts (callback-only, never drives
deliverOutboundPayloads) and add outbound-tool-trace-sanitize.test.ts which
exercises the shared delivery pipeline through the send-dependency boundary.

Co-Authored-By: Claude <[email protected]>
deliverOutboundPayloads drives the msteams channel with a send dependency
that POSTs to a local HTTP server — capturing the exact text that would
reach the Bot Framework API. Proves tool-trace banners are stripped and
trace-only payloads suppressed before the transport layer.

Update for re-review

  • Removed scripts/proof/msteams-sanitize-transport.mts (synthetic deps.msteams sender bypass).
  • Rebased onto latest main; PR diff is now 3 msteams files only.
  • Regression proof: node scripts/run-vitest.mjs extensions/msteams/src/outbound-tool-trace-sanitize.test.ts extensions/msteams/src/channel.test.ts22/22 passed.
  • PR body updated with ## Real behavior proof section.

Live Gateway + Bot Framework Teams session capture is still pending (no bot credentials in this environment). Please re-evaluate patch correctness now that the synthetic transport script is gone.
