Problem

A secretRef only works in the project of the thread that requested it. When an agent uses one for a scheduled task in another project, schedule_task fails with "That secretRef was already used or does not exist. Ask the user again with request_secret." The agent follows that advice from the same thread, gets another ref for the wrong project, and fails again. The user is asked for the same secret over and over.

Reproduced on main ae521d1 with a dev server on a fresh database and a Claude agent using the T3 MCP tools:

  1. A thread in project A calls request_secret, and the user saves a value.
  2. It calls schedule_task for project B with a webhook signature.secretRef. The call fails with the message above.
  3. The agent calls request_secret again, and the retry fails the same way.

Change

SecretRequests.readRef used to return ref_unavailable both for a missing ref and for one stored under another project. It now returns a new reason, ref_wrong_project, when the ref belongs to another project. Its message is "That secretRef was entered in another project. Ask with request_secret from a thread in the project that uses it." Used and missing refs still get ref_unavailable.

Project scoping is unchanged. The project check still runs before the expiry check, so a wrong-project caller never deletes or spends the value, and the owning project can still use the ref afterwards.

Scope and approval

Fixes #27776

Verification

  • vp test run apps/server/src/secrets/SecretRequests.test.ts apps/server/src/scheduledTasks/ScheduledTaskService.webhook.test.ts apps/server/src/provider/AgentContextBudget.test.ts: 64 passed.

    • "a ref only works in the project it was entered for" now requires ref_wrong_project, a message naming another project, and a later same-project consume that still returns the value.
    • On main it fails with expected 'ref_unavailable' to equal 'ref_wrong_project'.
  • vp run check:changed: format, lint, knip, typecheck (35 packages) and tests all pass. The MCP tool list size is unchanged.

  • Runtime, using a vp run dev server on a fresh database (T3CODE_DEV_SEED=0), projects A and B, and a claudeAgent/claude-sonnet-5-5 thread in project A. The thread calls request_secret, the user saves a synthetic value in the card, and it then calls schedule_task for project B with that ref.

    Before, on main ae521d1, the agent re-asks the user and fails again:

    schedule_task -> {"_tag":"OrchestratorMcpFailure","code":"orchestration_error","message":"Could not schedule task: That secretRef was already used or does not exist. Ask the user again with request_secret."}
    request_secret -> {"status":"saved","secretRef":"secret-ref:f276a3de…"}   (second card, same thread)
    schedule_task -> same error
    

    Control on main: a ref requested from a thread in project B schedules the project-B task. Reusing that spent ref fails with "already used or does not exist", which is correct.

    After, on this branch's final head, with a neutral prompt ("if something fails, work out from the error what would fix it"):

    schedule_task -> {"_tag":"OrchestratorMcpFailure","code":"orchestration_error","message":"Could not schedule task: That secretRef was entered in another project. Ask with request_secret from a thread in the project that uses it."}
    

    The agent did not ask again from the same thread. It explained that the ref is tied to the requesting thread's project and proposed requesting the secret from a thread in project B, then scheduling from there.

Before (main ae521d1): after the first schedule_task failure the agent asks for the secret again

The before screenshot shows the agent re-asking for the secret on main after the first schedule_task failure. All data in these runs is synthetic.

Not checked: other providers' agents (the change is in the shared server error text, not in any adapter).

…issing (#27776)

These tests reproduce #27776: consuming a secretRef from a different
project fails with ref_unavailable, whose message tells the agent to ask
again from the same thread, which cannot work. The test now expects a
distinct ref_wrong_project reason that names the project mismatch, and
that the wrong-project attempt does not spend the ref.

…eady used"

A secretRef only works in the project of the thread that requested it, but
using it from another project failed with ref_unavailable, which tells the
agent the ref was used or missing and to ask again. From the same thread that
mints another wrong-project ref and the agent loops, re-asking the user.

readRef now reports ref_wrong_project for a project mismatch, with a message
that names the other project and how to recover, still before the expiry
check so a wrong-project caller never spends or deletes the value. The
secretRef descriptions on request_secret and webhook signatures note the
project scope.

Approvability

Verdict: Approved at 610bed6

Macroscope's review found this PR approvable — Cross-project secret references now explain the project mismatch rather than reporting that the reference was already used. Secret access and deletion safeguards remain unchanged.

Walkthrough

Wrong-project secret refs now return a distinct failure reason and guidance. Missing or undecodable refs still return ref_unavailable. The test checks the wrong-project reason.

Changes: Secret ref project-scope errors

Layer / File(s) Summary
Wrong-project failure response
packages/contracts/src/secretRequest.ts, apps/server/src/secrets/SecretRequests.ts, apps/server/src/secrets/SecretRequests.test.ts
The failure contract adds ref_wrong_project and guidance for requesting the secret in the correct project. readRef returns this reason for project mismatches before checking expiry. The test checks the reason.

Explanation

The description covers the problem, reproduction steps, implementation, project-scoping behavior, linked issue, focused tests, broader checks, runtime verification, and unverified provider coverage. It follows the required sections and provides sufficient detail.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff changes only SecretRequests.test.ts, SecretRequests.ts, and packages/contracts/src/secretRequest.ts. These changes implement the wrong-project error, preserve non-consuming project checks, define the new message, and test the behavior required by issue #27776. No unrelated change appears.

Full details: Linked Issues check

Explanation

Issue #27776 requires a distinct wrong-project error while preserving project scoping. The PR meets this requirement. SecretRequests.readRef returns ref_wrong_project before expiry handling, and the contract message gives project-specific recovery guidance. The test confirms that a wrong-project read does not consume the ref and that the owning project can consume it later. Issue #27776 also requires the request_secret and schedule_task tool descriptions to explain project scoping. The current descriptions in apps/server/src/mcp/toolkits/orchestrator/tools.ts do not state that a secretRef works only in the requesting thread's project.

Resolution

Update the request_secret and schedule_task descriptions to state the project-scoping rule and the correct project for secret use. Add or update automated tests that verify the descriptions contain this guidance.

Evidence

Real web client, Chromium, 1280×800, light theme; fresh synthetic state on each commit. Request and save a signing secret in Project A, then use its secretRef to schedule a webhook task in Project B with bindToCurrentThread:false. Reuse the original ref in A, then request a fresh secret from B's thread and configure B's task.

Proven: scenarios:prove exited 0, failing on base and passing on head. Base reports “already used or does not exist”; head explains that the ref belongs to another project and directs request_secret from a thread in the destination project. The original ref remains usable in A on both commits, and destination-project recovery succeeds on both.

Evidence Before — 0d36f2b48e After — d1feaa023f
