Asked to run a command that needs a sudo password (run sudo dnf update for me), agents in T3 Code stopped, said they could not type a password, and told the user to run it themselves or add a NOPASSWD sudoers rule. They never called request_secret, which already delivers a secret to a shell command through a private file. I reproduced this on main 8d012a688e in the real app, with a sudo on PATH that requires a password: 0 of 5 runs called the tool (Claude Opus 5.5 ×3, Sonnet 5.5, Codex gpt-6.1-sol). Codex failed the same way, so this is not Claude-only.
Every provider gets the shared T3 instruction, and its secret bullet never linked a password prompt from a requested command to request_secret; Claude cannot see the tool's own description because it sits behind ToolSearch. The bullet (main's wording since #33157, plus the sudo recipe) now reads:
- A login, token, PIN, pairing code or sudo password only the user can give: call
request_secret, not a chat ask or a handoff. Not for access you have. Sudo: ifsudo -n <cmd>says a password is required, usedelivery: "file"and runsudo -S -p '' <cmd> < "$file"; the password takes stdin, so give other input as a file argument. When asked only to schedule,schedule_taskwithout running its prompt.
It adds 199 bytes per turn over main for Claude and for Codex (agentContextBudget.json moves to the measured sizes). An earlier, longer wording added 428; it was cut down clause by clause against the evals below, keeping only what a case needed:
sudo -n first, retry only on a password prompt: sudo -n saying a password is required proves sudo will ask for one. A plain nonzero exit is not enough: under passwordless or cached sudo the command already ran, and retrying would run it twice. Without it, Sonnet asked for a password on a passwordless-sudo machine in 2 of 4 runs, and a command exempt from authentication would get the password on its stdin. It also makes -k unnecessary: sudo -n only fails when no credentials are cached.printf x | sudo -S -p '' tee /etc/f < "$file" drops the pipe and tee truncates /etc/f (seen on real sudo 1.9.15p5 and sudo-rs 0.2.8). Without this clause Sonnet piped into sudo -S tee in 4 of 4 runs. Askpass (-A) would keep stdin free, but sudo-rs 0.2.8, the default on Ubuntu 25.10, rejects it.-y instruction (agents added it themselves in every apt/dnf run) and "don't hand the command back or suggest passwordless sudo" (naming sudo was enough; no run did either).The recipe keeps the password off the command line and out of chat. It does not hide it from the elevated command, which runs as root and could read the secret file anyway.
New cases in evals/mcp-tool-use/cases/secrets.ndjson, sourced from #27710, graded with main's secret checks (chatAsk, askTools; the sudo-password cases also require the password file to be consumed by sudo -S/--stdin, and the controls check noCardDemand): three sudo-password cases (the issue's dnf update, a write to an /etc file that agents pipe into sudo tee, and an apt install the agent has to pick out itself) and two controls (passwordless sudo, and a task with no sudo). run.test.ts now lets a secrets case cite an issue as its source, not only a field finding.
Sudo cases, final wording after merging main, strict grading (each sudo case must run its own command through sudo -S/--stdin with the password file, or validate with sudo -S -v; -Sp and --stdin are caught by the pipe rules):
| Case | Sonnet 5.5 | Opus 5.5 |
|---|---|---|
sudo-password-dnf-update | 4/4 | 4/4 |
sudo-password-write-etc-file | 14/24 across six runs (latest 2/4) | 4/4 |
sudo-password-apt-install-for-tests | 4/4, then 3/4 on the last wording (the miss is main's chat-ask detector flagging advice to give the Postgres user a password) | 4/4 (one sample rescored after fixing the grader to read quoted sh -c '… && apt-get install …') |
control-sudo-passwordless | 4/4 | 4/4 |
control-no-sudo-version-check | 4/4 | 4/4 |
Known weakness: on the /etc write, Sonnet still sometimes runs echo … | sudo -S tee -a FILE < "$file" (sudo takes the password, tee appends nothing) or < <(cat "$file"; echo …) (the file has no trailing newline, so authentication fails). Neither leaks the password or damages the file; the line just isn't written. Main passes this case 0/4 on both models. A further clause aimed at the pipe was not added, to keep the per-turn cost down.
Main's wording fails the three sudo cases (Sonnet: 1/2, 0/2, 0/2 on main after #33157; 0/4 on both models before it).
All 33 secrets cases on Sonnet 5.5, 2 samples each: main 77% of 66 samples, this PR 86%. Two of main's cases dipped to 1/2 (secret-cli-deploy-token, secret-staging-denied-guard); rerun at 6 samples on both wordings they are noise (PR 5/6 and 6/6, main 6/6 and 5/6). secret-sim-sandbox-login went from 0/2 to 2/2. The three cases that fail on main (secret-child-signin-wall, secret-live-check-declined, secret-live-check-skipped) fail the same here.
Before the merge (on the pre-#33157 bullet): the full non-device suite on Sonnet passed 92% of 195 samples on main and 95% of 193 with this change; no case went from passing to failing. Comparing wordings there, 4 samples per case:
| Case | Sonnet: main / longer wording / short wording | Opus: main / longer / short |
|---|---|---|
sudo-password-dnf-update | 0/4 · 4/4 · 4/4 | 0/4 · 4/4 · 4/4 |
sudo-password-write-etc-file | 0/4 · 4/4 · 3/4 | 0/4 · 4/4 · 4/4 |
sudo-password-apt-install-for-tests | 0/4 · 4/4 · 4/4 | 0/4 · 4/4 · 4/4 |
control-sudo-passwordless | 4/4 · 4/4 · 4/4 | 4/4 · 4/4 · 4/4 |
control-no-sudo-version-check | 4/4 · 4/4 · 4/4 | 4/4 · 4/4 · 4/4 |
Total eval spend: about $55.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — Agents are now instructed to request sudo passwords through the private secret card and pass them to sudo using file-backed stdin. This changes the default credential-handling interaction and requires human confirmation of the intended behavior.

Explanation
The title names the provider-core fix and the behavior it changes: agents ask for a sudo password through the private secret card. The changeset matches this. It edits the shared orchestration instructions, adds a sudo recipe for request_secret, and adds tests and sudo eval cases. The title follows the conventional commit form the template asks for. It is specific enough for a teammate scanning history to see the main change.
Explanation
Directly linked issue #27710 requires that, when an authorized command needs a sudo password, the agent calls request_secret with delivery: "file" and uses the private file as command input, without exposing the password and without the user naming the tool or granting passwordless sudo.
Whole-PR diff at head 4cfa2e8bb (base d0f1f7200) for packages/provider-core/src/server/orchestrationInstructions.ts changes the secret bullet. The bullet now covers "a sudo password" for "a login, token, PIN, pairing code or sudo password only the user can give". It directs the agent to call request_secret, not a chat ask. For sudo, it says: once sudo -n <cmd> fails, use delivery: "file" and run sudo -S -p '' <cmd> < "$file". It also says other input must be a file argument, because the password takes stdin. This matches the requested flow.
The instruction is part of the shared T3 instructions that every provider receives. The T3 tools may load late bullet remains, so deferred tool discovery is addressed by existing guidance. The PR summary reports a unit test that asserts the sudo guidance, and the budget files were updated.
Not verified: runtime behavior at head 4cfa2e8bb. The live runs and eval results in the PR description name earlier heads (9eef6b9648, 435ad5ea0a). The head wording differs from the wording used in those runs, and the eval results for the final wording come from the PR description, not from a run I could inspect. The coding requirement is met by the instruction text at head. Model compliance is supported by the reported evals but not independently confirmed here.
Explanation
Changed areas at head 4cfa2e8bb, compared with merge base d0f1f7200:
orchestrationInstructions.ts: the secret bullet now names sudo password prompts. This implements #27710.orchestrationInstructions.test.ts: tests the sudo guidance, the sudo -n <cmd> step, and the file-argument rule. Supporting test for #27710.agentContextBudget.json: claudeSystemAppendBytes moves from 5350 to 5529 and codexAdditionalContextBytes from 7080 to 7259. Each is a 179-byte increase, which matches the instruction size change. Supporting measurement.evals/mcp-tool-use/cases/secrets.ndjson: five cases for sudo password requests and controls (passwordless sudo, and a version check with no sudo). These are evals for #27710 and do not change production behavior.evals/mcp-tool-use/run.test.ts: lets a secrets case cite an issue as its source. Supporting test-harness change for the new cases.No new credential storage, sudo permission, or unrelated production behavior appears in these changes.
Limit: the text diffs for the eval file and run.test.ts could not be read at head. Their content comes from the supplied change summary. The summary describes only sudo-related cases. One eval expectation requires a non-interactive confirmation flag on package-manager commands. The instruction text does not state this flag. This is an eval grading rule, not production behavior, so it does not change this result.
Explanation
The description follows the repository template closely. It has the Problem, Change, Scope and approval, and Verification sections, and it includes the model and harness that did the work. Problem and Change are detailed and tied to the reproduction. Verification lists focused tests, real-app runs, real-sudo probes, and unchecked areas. Scope and approval is the weak point: it reads 'Fixes pingdotgg/t3code#27710' and does not state maintainer approval of direction or scope, or explain why an exemption applies. The linked issue body in the objectives describes the requested behavior, which partly supports scope, but the template asks for explicit maintainer approval or an approval comment. The description also has a long tail of eval tables and transcripts. That does not break the template, but it makes the description heavy. The description is mostly complete. One required element is incomplete, so the check is a FAIL only if that element is treated as critical. Under the policy, the description is mostly complete, so the check passes with a note on the approval gap.

The values are the measured cost of the fix: +428 bytes per turn for Claude and for Codex. The fix needs the added text, because Claude cannot see request_secret's own description behind ToolSearch. The agent-context-increase label is a maintainer decision, so this stays open for one.
@juliusmarminge Understood. The current values are each 428 bytes above the previous budgets. Reducing them without reducing the instructions would misstate the measured cost.
This thread should remain open for a maintainer’s agent-context-increase decision, not a code reduction.

Preserve user approval for command confirmations.
The instruction adds -y whenever a command asks for confirmation, even if the user asks to review the proposed changes first. For example, apt full-upgrade can remove installed packages, and -y approves the prompt without review. (manpages.debian.org)

✅ Addressed in commits 52aeb5d to c45eb6c
-y is there for a mechanical reason: with -S the command's stdin is the password file, which is empty after the password. A confirmation prompt can't be answered and aborts. The command fails safely, but the user's request is not done. The instruction applies only to a command the user asked to run, and it doesn't override a user who asks to review first. Whether agents should add -y by default or stop and ask is a product call, so this stays open for a maintainer.
@juliusmarminge Understood. The -y guidance addresses the stdin constraint in the password-file flow. My finding overstated this as a confirmed correctness defect and assumed that it overrides an explicit request to review first.
The remaining question is the product policy for automatic confirmation on user-requested commands. I’ll leave the thread open for a maintainer decision, as requested.

🤖 Claude Opus 5.5 responding on behalf of caniko
Before this ships as the default, there's a design question about sudo: whether the agent should get the password at all.
With delivery: "file", the agent writes the command that reads the file, so the password is a reusable credential in the agent's hands. Nothing stops a later cp "$file" …, a second sudo -S with a different command, or a prompt-injected tool call from using it. The PR notes the elevated command can read it. The bigger exposure is the unelevated agent shell, which can read it before or after. In full-access mode no approval card sits between that file and any command.
An alternative where the secret never reaches the agent:
We're building the local polkit half for NixOS activations: an agent requests an activation, and root asks the person at the seat via the OS dialog. A T3-native approval surface, especially remote passkey approval, would be the natural complement. Would maintainers prefer that direction over secret-card sudo, or should it be a separate issue?

🟠 High server/orchestrationInstructions.ts:19
A privileged command that exits nonzero can be run twice, duplicating mutations or corrupting state. sudo -n still executes the command when credentials are cached or NOPASSWD applies, so its nonzero exit status also triggers the documented sudo -S retry; only retry when the failure specifically indicates authentication is required.
✅ Resolved in c45eb6c473b5dbae9634c643856ac0856065d0e6
Right. Fixed in c45eb6c: the retry now fires only when sudo -n <cmd> says a password is required, not on any nonzero exit, so a command that ran under passwordless or cached sudo and then failed is not run again.
c45eb6c fixes this, but it isn't in the current PR branch. The current instruction still says to retry whenever sudo -n <cmd> fails.

Retry only after an authentication failure.
sudo -n <cmd> can run <cmd> and return its nonzero exit status. If the command changes a file before failing, treating that status as a password prompt can cause the agent to request a secret and run the command again. Check that sudo reported a required password and did not run the command before using the sudo -S retry. (man7.org)

@juliusmarminge I couldn’t verify c45eb6c because it is not in the checkout. At revision dc7a575, Line 19 still says to retry when sudo -n <cmd> fails.
Please push the commit to the PR branch if needed, then ask me to retry the check.

Require the password file to reach sudo.
These cases accept any Bash command containing secrets/files/. For example, test -e <file> passes after request_secret, even if the agent never runs sudo. fileUse: "safe" only rejects printing or copying; it does not require consumption. The reported pass rate can therefore count an incomplete sudo flow as a success. Require consumption by the intended sudo command, using declared consumers or equivalent checks.

Cover sudo’s --stdin option in the forbidden commands.
The patterns only match short options ending in S. For example, sudo --stdin dnf update < <file> passes the confirmation check without -y, although the fixture says it aborts. The same gap lets a piped sudo --stdin tee bypass the truncation checks. Match --stdin and combined short options too. (man7.org)

Both fixed in the latest commit. The three sudo-password cases now use fileUse: "consume" with a sudo -S/--stdin consumer, so test -e <file> fails with secret.fileConsumed; and every sudo pattern matches --stdin as well as short options ending in S. New grader tests in run.test.ts cover both, and a rerun under the stricter grading passes 4/4 on every sudo case on Sonnet 5.5 and Opus 5.5.

@juliusmarminge I checked head 52aeb5d. The changes address test -e and --stdin, but two gaps remain:
sudo -S command. For example, sudo -S true < <secret-file> can earn consumption credit without running the requested operation.S at the end. It misses -Sp, so unsafe commands using that form bypass shellMustNot if another command has already earned consumption credit.Please add case-specific consumers and cover S anywhere in a combined short-option group. I checked the patterns but did not run the grader tests.

Both addressed in dc7a575. Each sudo-password case now has its own consumer: sudo -S/--stdin must run that case's command (dnf update, the sysctl file or reload, apt-get install), quoted sh -c '… && …' included, or validate with sudo -S -v before sudo -n. So sudo -S true < file no longer earns credit. Short options match S anywhere in the group (-Sp). Grader tests in run.test.ts cover each form.

@juliusmarminge Thanks. I checked dc7a575: the case-specific consumers reject sudo -S true, and the patterns cover -Sp.
One gap remains. A standalone sudo -S -v < <secret-file> can earn consumption credit without a later sudo -n command. The case expectations do not require that later command, so an incomplete flow can still pass.
Please require the case-specific operation after -v and add a test for standalone validation. I inspected the grader but did not run the tests.

This test pins instruction copy rather than executable behavior, contrary to What to test. Could you remove the new secret-instructions test?
No longer relevant as of c45eb6c473b5dbae9634c643856ac0856065d0e6
Agreed, removed in c45eb6c. The new sudo cases in evals/mcp-tool-use/cases/secrets.ndjson cover the behavior instead.

@caniko Thanks, this is a real question and a good proposal. We're landing this PR as is: agents in full-access mode can already run anything as the user, and request_secret file delivery already hands them API tokens the same way. This change only stops agents from giving up on sudo, or suggesting NOPASSWD, when the user asked them to run something.
Elevation bound to one exact operation, approved in T3 and performed by the OS (polkit or Authorization Services locally, a passkey assertion for remote clients), so the agent never holds the password, is a bigger design than this bullet. Could you open it as an Ideas discussion, with the NixOS activation flow you're building as the motivating case? It would be a good place to work out how a T3 approval card and a host-side verifier fit together.
