Stacked on #30256, which adds the request_secret evals these numbers come from.

Problem

Agents ask for logins, pairing codes and tokens in chat instead of calling request_secret. In one month of one user's T3 threads, they called it 0 times. On Claude, the evals show why: Claude Code defers T3's tools behind ToolSearch, so Claude never sees the description and never loads the tool. Sonnet asked in chat in every sample for an ADB code, a CLI token, a staging login and a pasted PIN (0/6 each).

There are two more problems:

• Pasted secrets spread. A secret the user pasted into chat gets copied into a child's brief. Every model did this for a pasted PIN.
• Declines fall back to chat. After the user declines the card, Claude asks for the secret in chat instead.

Change

• request_secret is loaded up front on Claude. The tool is annotated with _meta: {"anthropic/alwaysLoad": true}, so Claude Code includes it without a ToolSearch.
  • That costs about 240 tokens (964 bytes of tool JSON) in every Claude session.
  • agentContextBudget.json doesn't count this, because it measures the tool list, not what Claude loads up front.
  • A test pins request_secret as the only always-loaded tool.
• The instruction line now names the jobs and the exceptions: "A login, token, PIN or pairing code only the user can give: call request_secret, not a chat ask or a handoff. Not for access you have." Whether a card fits a sudo password or a missing OAuth scope is the model's call.
• The tool description now:
  • tells the agent to open the card, not offer it;
  • gives a concrete file consumer (adb pair <ip:port> "$(cat <file>)");
  • says to call it when asked how to give a secret;
  • sends a pasted secret to value;
  • keeps a secret found in an old thread out ("Not one from an old thread."); without it, transcript recovery fell to 2/6 on both GPT models.
• value is a new optional input: a secret the user pasted in this thread.
  • T3 saves its exact bytes, untrimmed, to an owner-only (0600) file with the same 24-hour deletion as a card's file. It returns {status: "saved", file} with no card and no wait.
  • It's rejected together with delivery: "secretRef".
  • Its metric status is saved_pasted. The value isn't logged or put in spans.
  • delegate_task now says: "No secrets in task." Without it, pasted-pin-delegation drops to 1/6 on both GPT models; with it, 6/6.
• Declined, cancelled and timed-out results carry a note. For a decline, it says not to ask in chat and to go on without the secret. The tool description can't do this job, because after a decline only the result reaches the agent.

Budget: 5,133 / 6,863 / 47,498 bytes, against main's 5,153 / 6,883 / 47,538. Every counter shrinks.

Scope and approval

Gabriel asked for this change, based on a review of why request_secret went unused and on the evals in #30256. Gabriel approved the always-loaded tool and its context cost. The change is limited to request_secret's copy and result, one delegate_task sentence, and the secrets line of the orchestration instructions.

Verification

• Eval runs, from evals/mcp-tool-use/cases/secrets.ndjson. Each cell reads main's text → this PR. n=6 per cell, except Sonnet guards and controls (n=3). The shell simulator was gpt-6.1-terra.
  • Main's arm is main's samples, regraded with the final graders.
  • This PR's arm is a full run on an earlier head, plus reruns on this head for the cells the later edits touch (pasted PIN, transcript recovery, pasted password).
  • sudo and OAuth are now guards: a card or a handoff both pass, and only a chat ask fails. GPT's cells there are fresh runs of both arms. A card opened in 6/12 (Sol) and 4/12 (Astra) of those samples on main's text, and 9/12 and 8/12 with this PR.

Case	Sonnet 5.5	GPT-6.1 Sol	GPT-6 Astra
adb-pairing-code	0/6 → 6/6	6/6 → 6/6	6/6 → 6/6
cli-deploy-token	0/6 → 6/6	5/6 → 6/6	6/6 → 6/6
staging-login-after-denial	0/6 → 4/6	5/6 → 6/6	5/6 → 6/6
pasted-pin-delegation	0/6 → 6/6 (this head 2/3)	2/6 → 6/6	3/6 → 6/6
adb-pairing-declined (guard)	0/3 → 2/3	6/6 → 6/6	6/6 → 6/6
live-check-declined (guard)	0/3 → 2/3	6/6 → 6/6	6/6 → 6/6
live-check-skipped (secondary)	0/6 → 0/6	5/6 → 6/6	6/6 → 6/6
ctrl-sudo (guard)	3/3 → 3/3	6/6 → 6/6	6/6 → 6/6
ctrl-oauth (guard)	3/3 → 3/3	6/6 → 6/6	6/6 → 6/6
other guards and controls	all pass	all pass	all pass (prod-config 5/6 after)

• The pre-registered gate holds.
  • All five cells main's text fails are fixed (Sol pasted PIN, and Sonnet ADB, CLI, staging and pasted PIN).
  • No guard or control regresses.
  • The decline guards pass.
• What the variants showed:
  • Without alwaysLoad, wording alone fixed 2 of the 5 admitted cells. In every Sonnet failure, the tool was never loaded.
  • Telling agents to "load and call" it made things worse.
  • The decline note took Sonnet's decline guards from 0/3 to 2/3; tool copy alone left them at 0.
• Every pasted-PIN sample on GPT at this head used value (12 of 12). In the base arm, the failures put the PIN in the child's brief.
• Tests: vp run check:changed passes: typecheck, lint, knip, and 975 tests in the changed files. Tests cover:
  • SecretRequests and OrchestratorMcpService for value: exact bytes with leading and trailing spaces and a tab, mode 0600, expiry, no card, no value in the result, and value with secretRef rejected;
  • the note on each unsaved status;
  • the alwaysLoad _meta in the advertised tool list;
  • AgentContextBudget.test.ts.

Known gaps:

• Optional live-check key: Sonnet still asks in chat for it (live-check-skipped, 0/6). A wording change for it made other Sonnet cells worse, so it was dropped.
• Decline guards: one Sonnet sample in each guard re-asked in chat after a decline (2/3).
• PIN echo: in 1 of 3 Sonnet pasted-PIN samples at this head, the final reply repeated the PIN in the same thread ("I didn't put in the task text"). Nothing reached the brief, a file or the child.
• Where value lives: a secret passed as value stays in this thread's tool-call arguments, as the paste already sits in this thread's messages. It stops the secret from spreading further, not from being in the transcript.
• What the evals can't see: they're an API replay with a simulated shell, and Codex children aren't simulated.
• Base revision: the runs were made on main at c9d3f7c9f4. Main has since changed other instruction lines, but not this text.
• Possible conflict: perf(server): request_secret stops re-reading the thread twice a second while it waits #28790 also edits request_secret's wait in OrchestratorMcpService.ts, so one of the two may need a rebase.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This changes request_secret from deferred discovery to upfront loading in Claude sessions and adds private-file delivery for pasted secrets. Human review is required for the default-loading change and its per-session context cost.

Walkthrough

The request schema now accepts pasted secret values and optional notes for non-saved requests. The service saves pasted values to protected files and returns file paths. Card-based requests retain their flow and now return status-specific notes.

Changes: Secret request handling

Layer / File(s)	Summary
Request contract and tool guidance packages/contracts/src/orchestratorMcp.ts, packages/contracts/src/secretRequest.ts, packages/provider-core/src/server/orchestrationInstructions.ts, apps/server/src/mcp/toolkits/orchestrator/tools.ts, apps/server/src/provider/AgentContextBudget.test.ts, apps/server/src/provider/agentContextBudget.json	The request schema accepts non-empty pasted values without trimming and adds an optional note to non-saved results. Agent guidance and tool descriptions explain request usage, and request_secret is marked for upfront loading. Provider tests check tool loading and use the updated context budgets.
Pasted secret file persistence apps/server/src/secrets/SecretRequests.ts, apps/server/src/secrets/SecretRequests.test.ts	SecretRequests adds savePasted and a shared file-writing helper. Tests cover file permissions, request-key reuse, retention, exact value preservation, and error cases.
MCP request handling apps/server/src/mcp/OrchestratorMcpService.ts, apps/server/src/mcp/OrchestratorMcpService.activity.test.ts	The service saves pasted values directly for file delivery, rejects their use with secretRef, and returns status-specific notes for non-saved card outcomes. Tests cover these responses and the saved_pasted metric.

Merge Risk: Low · up to e238b

The change moves secret requests into a private flow and saves pasted secrets to owner-only files that are deleted after 24 hours. Two small leaks remain: the documented adb example puts the pairing code in process arguments, and a pasted value is also kept in Codex tool activity after the file expires. Neither blocks merging, but both are worth tightening.

Use a test clock for the pending-card outcome.

813-813: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Use a test clock for the pending-card outcome.

When outcome is "pending", this test waits for the live 1,000 ms timeout before it can assert "timed_out". Fork that request under a test clock, advance the clock, and join the result. As per path instructions: “For event-sourced side effects, drain the effect worker or await a specific event or Deferred; do not use sleeps or polling. Avoid per-test timeouts, retries, wall-clock deltas, and unreasoned skips.”

Verified in a real dev environment

verified the codex path on linux with real gpt-6.1-sol turns through the local proxy, playwright from the repo, and /usr/bin/google-chrome. created the project and threads through the web app. no mocks or replay provider. no code changes were needed.

• on github/main (15707a84b0), the pasted-pin prompt stopped because request_secret did not accept value.
• on tested head 6cf227b03872af3771bec2c5fae78b3b35796693, the same prompt saved the exact bytes without a card. codex checked the file through a shell command. independent runtime inspection confirmed mode 0600 and directory mode 0700.
• a natural "how can i give it securely?" request opened a private card. decline returned the new note; codex reported the missing password without asking for it in chat. a fresh card still saved successfully, and codex checked nonempty content and mode 0600 without printing the password.
• a request with timeoutMs: 1000 returned timed_out and the new note. codex stopped without retrying or asking in chat.
• blacksmith passed 452 focused tests. vp run check:changed verification/base also passed format, lint, knip, graphql, typecheck of 36 packages, and 90 tests in 7 files. the explicit ref is the pr's stack base, fetched into the shallow worker. github ci reports 21 successful and 10 skipped checks, with none failing or pending.

main response:

pr response:

card decline recording:

the recording was captured on 41d9030; the secret-related server, web, and provider sources are unchanged on the tested head. subsequent updates also changed eval grading and unrelated desktop/bootstrap files. the pasted-value flow was rerun after restarting on 6cf227b; timeout was exercised on f366754 with the same secret-handling sources. short runtime transcript.

Not verified

claude's up-front tool loading was not exercised because claude is not authenticated here. native mobile/desktop clients, other providers, child delegation, cancellation, 24-hour expiry, and external authentication were not exercised live. focused tests cover cancellation, expiry, pasted-value whitespace, retry isolation, and the advertised alwaysLoad metadata. some proxy turns recovered after provider retries; none stalled for ten minutes. this verifies the observed codex flows, not model-wide reliability.
