fix(orchestration): a subagent's approval prompt is the person's, never its orchestrator's - #195
Split out of #159 and rebased on current main (c5731f4): fixes 4 and 5 of #159. Small and independent; it does not depend on the other parts of #159. Fix 4 is unchanged in substance. Fix 5 is stricter than in #159: on an orchestrator's connection, choose/dismiss now act only on Codex menus known not to be approvals, instead of refusing only known approval texts (see "Behaviour change" below).
Behaviour change: an orchestrator can no longer choose/dismiss a Codex menu that is not on that short list (hooks review, model or rate-limit notice, update notice). A new Codex startup menu that is not on the list goes to the person until it is added. The person's own connection is unchanged.
Both fixes close the same gap from two sides: when a subagent's CLI asks for approval (a shell command, an edit, a permission), only the person, or a decision service the person allowed, may answer. The orchestrator could answer it through the canvastty_agents tools (fix 4, OpenCode) and through its own control connection (fix 5, Codex). Two commits, one per fix, and one review fix on top (see "Review fix" below). Fix 5's test also checks send_to_agent at every CLI's approval signal, so it uses fix 4's refusal.
Fix 4. An OpenCode subagent's shell prompt reached the orchestrator, not the person
fix(opencode): bring a subagent's shell ask to the person, never to its orchestrator
Problem
On a launch contributor's model, OpenCode keeps bash on "ask" (your rule, unchanged). In a live run, a subagent's ls prompt sat unanswered: wait_for_agent returned the same pending prompt on every call, so the orchestrator could only poll or give up. It could also have answered the prompt itself: send_to_agent typed into the card whatever its status, and the Enter after any text answers OpenCode's prompt.
Cause
AgentControlService.send did not check needs_approval, and wait_for_agent had no way to wait for the person's answer.
Fix
send_to_agent is refused while the subagent is needs_approval (INVALID_REQUEST, not retryable). Nothing is written, and the refusal tells the orchestrator to tell the person what it asks and call wait_for_agent again.
wait_for_agent returns a given prompt once. A later wait on the same prompt waits for the person's answer and then for the subagent's turn, so the orchestrator carries on in the same turn. A new prompt is reported at once again, also one that follows the last with no status change in between (see "Review fix").
bash is not allowed in any new case. A decision service's deny still fails the call before OpenCode asks, its allow (from a plugin the person let allow) still answers OpenCode's prompt once, and no verdict is never turned into an allow. Person cards and OpenCode on its own model are untouched; no new UI.
On main the change sits next to the newer paste/submit delivery: the refusal comes before deliver, so a refused prompt never reaches the delivery queue. The tool descriptions keep main's 50-second client-safe wait note and plain-text screen wording; native/canvastty-helper/catalog.json was regenerated with build-native-helpers.mjs --catalog (it matches the merged text).
Test
New tests/opencode-subagent-ask.test.mjs (2 tests). It runs the real OpenCode plugin module, RuntimeGateway, DecisionHooks, TerminalManager, AgentControlService and ScopedOrchestrationHandler, with no OpenCode and no model: allow answers the prompt, deny fails the call, no verdict reaches Needs attention and the orchestrator, send_to_agent writes nothing, and the person's answer resumes the subagent and the orchestrator's wait.
On main without the fix, the second test fails: without the needs_approval check send_to_agent is not refused, and without the once-per-prompt rule the second wait returns the same prompt at once. With the fix both pass.
Fix 5. An orchestrator could approve a Codex subagent's command through the control CLI
fix(orchestration): an orchestrator's control connection never answers a subagent's approval prompt
Problem
With its own control connection, an orchestrator could choose <id> --choice 1 on a Codex subagent's "Would you like to run the following command?". That approved the command for the person; dismiss answered it "No, and tell Codex what to do differently". The orchestrator skill even described these as menus choose/dismiss can act on.
Cause
choose/dismiss only checked that the menu was the one observed, not what it asks. send was refused there, but with a retryable NOT_READY that said "wait".
Fix
On an orchestrator's own connection (a session-scoped grant), choose, dismiss and send get NEEDS_PERSON, which is not retryable, writes nothing and tells the orchestrator to tell the person. Two checks, either of which refuses:
Status: the card is needs_approval, the status each CLI's own approval signal sets (Codex, Claude Code, Qwen and Kimi PermissionRequest, Grok's permission notification, Hermes pre_approval_request, OpenCode permission.asked/question.asked).
Screen, fail closed: Codex can draw its approval prompt before its hook's report arrives, and choose acts on that exact screen. So on an orchestrator's connection choose and dismiss act only on the Codex menus known not to be approvals: hooks review (and its "hooks reviewed" notice), the model or rate-limit notice, and the update notice. Any other Codex menu is refused, including folder trust (CanvasTTY already answers it for subagents inside the project), a permissions change ("Update Model Permissions"), and an approval worded in a way CanvasTTY does not recognise. Known approval texts (command, edits, permissions, network, MCP requests) are refused even if they appear next to an allowed title. send is also refused while a known approval is on screen; otherwise Codex's own empty-composer check already keeps text away from any menu.
Unchanged: the menus listed above stay the orchestrator's; status, screen and result still read; interrupt still stops its own turn (stopping is not an answer, and the asked call does not run); the person's own app-wide connection, the card's input and decision services are untouched.
Remaining limit: the screen check reads the visible Codex screen, so it is only as good as that screen. If Codex were to show an approval whose text matches none of the known approval patterns and also carries an allowed title (for example "Hooks need review") on its own line, before the hook report arrives, it would be treated as that menu. Once the hook reports, the status refuses it whatever the screen says.
Test
New tests/orchestrator-approval-answers.test.mjs (5 tests, the fifth from the review fix). It runs the real TerminalManager, AgentControlService, AgentControlGateway and control CLI request path over a socket with an orchestrator's session grant:
approval prompts are refused before and after the hook report, for choose (each option), dismiss and send, and the refusal replays for the same request id instead of writing;
an approval with unrecognised text is refused before the hook report (not a known menu) and after it (needs_approval); folder trust and a permissions menu are refused;
hooks review, the model notice, the "hooks reviewed" notice and the update notice are still chosen and dismissed, and the next task is still delivered;
the person's own connection still chooses its worker's approval prompt, and the orchestrator cannot reach that worker;
send_to_agent is refused at each CLI's approval signal (Claude Code, Codex, Grok, Kimi, Qwen, Hermes, OpenCode) and delivered once the person answered.
The tests use main's paste-then-submit delivery (an echoing fake composer, as main's own delivery tests do), so a delivered task is checked as its paste followed by the submit key.
On main without the fix, the first choose on the approval prompt writes the keys (the second test fails with "Missing expected rejection"). Without only the fail-closed menu check, the same test fails at the unrecognised approval before the hook report. With the fix all pass.
Review fix. wait_for_agent tracks each approval request, not the card revision
fix(orchestration): wait_for_agent tracks each approval request, not the card revision
The once-per-prompt rule told prompts apart by the card's revision, which is the wrong identity both ways:
A second PermissionRequest right after the person answered the first moves neither the status nor the revision (TerminalManager.applyProviderSignal returns early), so the new prompt was taken for the one already reported and the next wait ran to its timeout.
A card change that is not a new prompt (its thread id arriving, say) moved the revision and returned the same prompt again.
TerminalManager now counts approval requests per card (approvalRequest(id)): the count advances when the card turns needs_approval, and on each further request hook (PermissionRequest, pre_approval_request, permission.asked, question.asked) while it stays there. A permission_prompt Notification while the card already waits is the same prompt echoed (Claude Code and Qwen send both) and does not advance it. The count is never reset, so a relaunch cannot reuse a value a wait already saw. wait_for_agent compares that count instead of the revision. The CLIs give no per-prompt id in their hook reports (the requestId CanvasTTY gets is the turn id), so a counter is the identity available.
Test: tests/orchestrator-approval-answers.test.mjs, "wait_for_agent reports each approval request once, a consecutive one with no status change in between too" (Claude subagent: PermissionRequest, the echoed Notification and a thread-id change do not re-report; the person answers and a second PermissionRequest with an unchanged revision is reported at once; that one is reported once too; a Hermes-style pre_approval_request is new again). Before the fix it fails at the thread-id change ("the reported prompt waits for the person"); with that step removed it fails at the consecutive request (timeout instead of needs_approval). With the fix it passes.
Verification
npm run typecheck, npm run build and npm run audit:secrets pass.
Targeted: the two new test files with tests/auto-profile.test.mjs, tests/secret-redaction.test.mjs, tests/agent-control.test.mjs, tests/orchestration-providers-wait.test.mjs and tests/orchestration-gateway.test.mjs: all pass.
The renderer is untouched.
Full suite: 2706 tests, 2700 pass, 0 fail, 6 skipped (main at c5731f4: 2699 tests, 2693 pass, 0 fail, 6 skipped; the difference is the 7 new tests).
Summary by CodeRabbit
Bug Fixes
Approval and permission prompts must be answered by the person, not the orchestrator. Attempts to respond on the person’s behalf are refused.
After reporting an approval prompt, the orchestrator’s next wait waits for the person’s response instead of repeating the same prompt. New approval requests are reported separately.
Documentation
Clarified which startup menus an orchestrator may resolve and which prompts require the person’s response. Unrecognized menus are refused.
Clarified that approval prompts are presented to the person and that orchestrators must wait for their response.
…ts orchestrator
An OpenCode subagent on a launch contributor's model keeps bash on "ask"
(a launch contributor's other model keeps bash asking, like accept-edits
elsewhere). When no decision service decides, OpenCode's own prompt waits
in the subagent's card for the person. That part already works: the card
turns needs_approval, Needs attention lists it, and wait_for_agent
returns at once with the prompt in output. Two things stood in the way:
- send_to_agent still typed into that card. Any prompt text ends with
Enter, which answers OpenCode's prompt, so the orchestrator (on the same
third-party model) could approve the command for the person. It is now
refused while the subagent is needs_approval, with a reason that tells
the orchestrator to ask the person and wait.
- wait_for_agent returned the same pending prompt again on every call,
so an orchestrator could only poll or give up. It now returns a prompt
once; a later wait on the same prompt (the card has not changed since)
waits for the person's answer and then for the subagent's turn, so the
orchestrator carries on in the same turn once the person has answered.
A new prompt is reported at once again.
Unchanged: bash stays "ask" for a third-party model in every card; a
decision service's deny still fails the call before OpenCode asks and its
allow (from a plugin the person let allow) still answers OpenCode's
prompt once; no verdict is never turned into an allow; person cards and
OpenCode on its own model are untouched; no new UI.
The test runs CanvasTTY's real OpenCode plugin, runtime gateway, decision
hooks, TerminalManager and orchestration tools: allow answers the prompt,
deny fails the call, no verdict reaches Needs attention and the
orchestrator, send_to_agent writes nothing, and the person's answer
resumes the subagent and the orchestrator's wait.
…s a subagent's approval prompt
Asks are answered by the person, or by a decision service the person
allowed, never by the orchestrator. The canvastty_agents tools already
refuse send_to_agent while a subagent is needs_approval. The control
endpoint did not: on an Orchestrator session's own connection, choose
answered Codex's approval prompt ("1. Yes, proceed") and dismiss answered
it with Escape ("No, and tell Codex what to do differently").
On an orchestrator's connection, choose, dismiss and send are now refused
with NEEDS_PERSON (not retryable, nothing is written) while the worker
is needs_approval, the status each CLI's own approval signal sets. For
Codex's choose and dismiss the menu is also checked: Codex can draw its
approval prompt before its PermissionRequest hook's report arrives, and
choose acts on that exact screen. codexApprovalPrompt matches Codex's
command, edits, permissions, network and MCP approval prompts, not hooks
review, folder trust, model or update menus.
That text match alone would be a denylist, so choose and dismiss on an
orchestrator's connection also fail closed: they act only on the Codex
menus known not to be approvals (hooks review and its "hooks reviewed"
notice, the model or rate-limit notice, the update notice). Any other
menu, such as folder trust, a permissions change or an approval worded in
a way CanvasTTY does not recognise, is refused with NEEDS_PERSON as well.
Unchanged: hooks review and the model and update notices stay the
orchestrator's; status, screen and result still read; interrupt still
stops its own turn (the asked call does not run); the person's own
app-wide connection, the card's input and decision services are
untouched.
Tests run the real TerminalManager, AgentControlService, gateway and
control CLI request path with an orchestrator's session grant: approval
prompts refused before and after the hook report, an approval with
unrecognised text refused before the report (not a known menu) and after
it (needs_approval), folder trust and permission menus refused,
non-approval menus chosen and dismissed, the person's connection still
choosing, and send_to_agent refused at every CLI's approval signal and
delivered once the person answered.

Track approval identity instead of the general card revision
When a CLI issues another PermissionRequest without an intervening status transition—the consecutive Claude prompt case exercised in tests/auto-profile.test.mjs:417-422—TerminalManager.applyProviderSignal returns early at line 1396 without increasing revision. Consequently, this check treats the new prompt as already reported, even when its request ID and screen differ, and the orchestrator's next wait times out instead of immediately reporting the new approval. This delays notifying the person by up to the full wait timeout. Use a per-prompt identifier or generation that advances on a genuinely new approval request rather than relying on the general metadata revision.

Fixed in fix(orchestration): wait_for_agent tracks each approval request, not the card revision (d60d584). TerminalManager now keeps a per-card approval request count (approvalRequest(id)). It advances when the card turns needs_approval and on each further request hook (PermissionRequest, pre_approval_request, permission.asked, question.asked) while the card stays there, so a second PermissionRequest with no status change in between is a new request even though applyProviderSignal returns early and the revision does not move. A permission_prompt Notification while the card already waits is the same prompt echoed (Claude Code and Qwen send both) and does not advance it. The count is never reset, so a relaunch cannot reuse a value a wait already saw. wait_for_agent compares this count instead of revision. The hook reports carry no per-prompt id (the requestId we get is the turn id), so a counter is the identity available.
This also fixes the opposite case: a revision change that is no new prompt (the thread id arriving) used to return the same prompt again.
Test: tests/orchestrator-approval-answers.test.mjs, "wait_for_agent reports each approval request once, a consecutive one with no status change in between too". It follows the consecutive Claude PermissionRequest case from tests/auto-profile.test.mjs: after the first prompt is reported, the echoed Notification and a thread-id change do not re-report it; the person answers, a second PermissionRequest arrives with the revision unchanged, and the pending wait returns needs_approval at once; the wait after that waits again. Before the fix it fails (the thread-id change re-reports the prompt; without that step, the consecutive request ends in timeout). With the fix it passes.

Walkthrough
Approval prompts are tracked by request and reported once to the orchestrators. The control service refuses orchestrator responses while approval is pending. The gateway limits Codex menu actions to recognized menus. Documentation and tests describe and check these behaviors, including OpenCode third-party-model prompts.
TerminalManager tracks approval request counts. AgentControlService reports each request once and refuses sends while approval is pending. Tests cover OpenCode prompts, person responses, and subsequent waits.

Security architecture risk: Moderate · up to d60d5
Approval responses are more tightly restricted to the person, but the new request tracking can suppress information needed to resolve an approval. Direct inspection and timeout responses provide recovery, and no newly introduced approval bypass was demonstrated.
Retained concerns
Medium · reliability · inferred: The new once-only reporting state is committed before observing the approval screen and remains committed even if observation fails. Lifecycle events and terminal output arrive independently, so a hook arriving before the rendered approval can produce an immediate result with stale or empty output; later output does not make that request reportable again. Unlike the base's repeated immediate reports, recovery then requires explicit observation, direct card inspection, or a timeout response. This can stall the intended human-only authorization handoff; it does not establish an approval bypass.
Medium · reliability · inferred: All Notification events received while approval remains pending are treated as the same request, but Grok uses Notification as its approval-request hook. A distinct consecutive request without an intervening status transition therefore retains the previous counter and loses its immediate approval report. The base did not suppress such reports. Ordinary PostToolUse or idle transitions prevent this case, and timeout output or direct inspection can recover it; whether every real provider sequence guarantees such a transition remains unproven.
Security review details
Security Blast Radius
inferred — The sensitive outcome is terminal input answering a command, edit, permission, or trust decision under the target CLI's existing authority. Inspected controls bound these operations to owned sessions or the caller's subtree. The reporting concerns affect pending approval workflows, not demonstrated cross-session or cross-tenant access.
Security Findings and Attack Paths
inferred — The gateway diff adds restrictions before existing menu-write paths rather than creating a new approval capability. A hypothetical future approval sharing an allowlisted title would be a limitation of text classification, but the base already permitted those menu actions; it is not retained as an introduced or worsened vulnerability.
Trust Boundaries and Controls
observed — The direct orchestration send path delegates to terminal delivery, which independently checks approval status, launch identity, cancellation, and manual-input interruption. Codex delivery waits for its composer, and staged submission requires observing the paste before Enter. These controls counter the suspected bypass based solely on the service lacking the gateway's screen classifier.
Resilience and Maintainability Implications
observed — Read-only observation and timeout output remain available, limiting the reporting failures to delayed or misleading handoff rather than removing all recovery. Tests cover consecutive non-Notification requests and refusal at provider approval signals. The inspected OpenCode fixture emits permission events without rendering a real approval screen, so it does not establish lifecycle-to-screen ordering.
Hardening Proposals
proposed — Separate request identity from successful presentation: prefer provider request identifiers where available, distinguish Notification-only request producers from echo notifications, and permit bounded re-observation when the initial approval snapshot is unavailable or predates the request. Preserve the person-only write restrictions during recovery.

Autofix · Keep fixing CodeRabbit findings and required CI, and resolving merge conflicts
Maintainer review at 8ace7a9: the approval-identity finding is still a blocker. A second PermissionRequest can retain the same card revision, so the next wait can miss a genuinely new prompt. Please address the existing inline finding and add a regression for consecutive approval requests without an intervening status transition.
This changes orchestration behavior and requires the repository owner's hands-on acceptance before merging. Passing CI alone is not approval to merge.
…the card revision
wait_for_agent reports a subagent's approval prompt once and then waits
for the person's answer. It told prompts apart by the card's revision,
which is the wrong identity both ways. A second PermissionRequest right
after the person answered the first moves neither the status nor the
revision (applyProviderSignal returns early), so the new prompt was
taken for the old one and the next wait ran to its timeout. And a card
change that is no new prompt (its thread id arriving) moved the revision
and returned the same prompt again.
TerminalManager now counts approval requests per card: the count
advances when the card turns needs_approval and on each further request
hook (PermissionRequest, pre_approval_request, permission.asked,
question.asked) while it stays there. A permission_prompt Notification
while the card already waits is the same prompt echoed and does not
advance it. The count is never reset, so a relaunch cannot reuse a value
a wait already saw. wait_for_agent compares that count instead of the
revision.
Approval identity blocker: fixed, see 4437462980. The once-per-prompt rule now uses a per-approval request count instead of the card revision.
Regression for consecutive approval requests without an intervening status transition: added (see above); it fails before the fix and passes after.
Rebased onto current main (c5731f4) without conflicts; the original two commits are unchanged, the review fix is one new commit on top. The wait_for_agent row in docs/agent-orchestration.md now says a new request right after the last one returns at once.
CodeRabbit's docstring coverage warning: the functions this PR touches carry comments where the behaviour is not obvious; nothing else changed for it.
Typecheck, build and secret audit pass; the renderer is untouched. Full suite: 2706 tests, 2700 pass, 0 fail, 6 skipped, 0 failures (main at c5731f4: 2699 tests, 2693 pass, 0 fail, 6 skipped).
Ready for the owner's hands-on check: an orchestrator with a Claude Code subagent that asks for two permissions in a row; after the person answers the first, wait_for_agent reports the second at once.
I'm on vacation for about a month and will be mostly unavailable until then, so my replies will be slow. The branch is rebased on current main and the review fixes above are ready for review.
Assert the approval prompt in wait_for_agent output.
This test covers the approval state, but it does not cover prompt delivery. The fixture emits permission.asked directly without rendering the approval prompt, and the assertion checks only reason. A regression that returns needs_approval with empty or stale output would pass.
Make the fixture produce prompt-bearing terminal output, then assert that first.output contains the ls approval details. Use a unique prompt value if needed to distinguish fresh output from stale output.

Do not mark the approval as reported before its prompt is observable.
A real OpenCode permission.asked event can reach applyProviderSignal before the TUI has rendered the permission prompt into the subagent PTY. waitFor stores the approval revision before observe reads the buffer, so it can return needs_approval with empty or stale output. The next wait then sees the same revision and waits instead of returning the rendered prompt.
Associate each approval revision with the PTY output state for that request, and record it as reported only after the corresponding prompt output is observable. This preserves deduplication for repeated waits without losing a prompt that arrives after the status signal.

Update waitFor and the reportedApprovals tracking so an approval revision is
marked reported only after observe confirms its corresponding prompt is present
in the PTY output. Associate each revision with that request’s PTY output state,
preserving deduplication across repeated waits while allowing a prompt rendered
after applyProviderSignal to be returned.

Do not count Qwen’s matching hook as a second approval request.
The Qwen title and lifecycle hook use separate callbacks, so the title can set needs_approval before the matching PermissionRequest hook arrives. The title increments approvalRequests, and the hook increments it again. Because waitFor treats that change as a new request, the next wait can report the same prompt again.
Correlate the matching hook with the title-created pending request. Keep incrementing the counter for a distinct subsequent approval. Add a regression test for the title-then-hook sequence.

Update the approval-counting logic around session.approvalRequests so a
PermissionRequest hook matching a request already marked needs_approval by the
Qwen title does not increment the count again; preserve increments for distinct
subsequent approvals. Add a regression test for the title-then-matching-hook

Count consecutive Grok approval notifications as separate requests.
Grok uses Notification as its approval signal. When a second prompt arrives before the status changes, the current branch does not advance approvalRequests. waitFor can therefore suppress the second prompt.
Scope this change to Grok. Claude and Qwen use Notification as an echo in addition to PermissionRequest, so a global change would count those prompts twice.

Update the approvalRequests increment condition in the needs_approval branch so
consecutive hook Notification signals count as separate requests only when
session.metadata.provider is Grok. Preserve the existing echo handling for
Claude and Qwen and the current behavior for other signals.

Split out of #159 and rebased on current main (c5731f4): fixes 4 and 5 of #159. Small and independent; it does not depend on the other parts of #159. Fix 4 is unchanged in substance. Fix 5 is stricter than in #159: on an orchestrator's connection,
choose/dismissnow act only on Codex menus known not to be approvals, instead of refusing only known approval texts (see "Behaviour change" below).Behaviour change: an orchestrator can no longer
choose/dismissa Codex menu that is not on that short list (hooks review, model or rate-limit notice, update notice). A new Codex startup menu that is not on the list goes to the person until it is added. The person's own connection is unchanged.Both fixes close the same gap from two sides: when a subagent's CLI asks for approval (a shell command, an edit, a permission), only the person, or a decision service the person allowed, may answer. The orchestrator could answer it through the
canvastty_agentstools (fix 4, OpenCode) and through its own control connection (fix 5, Codex). Two commits, one per fix, and one review fix on top (see "Review fix" below). Fix 5's test also checkssend_to_agentat every CLI's approval signal, so it uses fix 4's refusal.Fix 4. An OpenCode subagent's shell prompt reached the orchestrator, not the person
fix(opencode): bring a subagent's shell ask to the person, never to its orchestratorProblem
On a launch contributor's model, OpenCode keeps
bashon "ask" (your rule, unchanged). In a live run, a subagent'slsprompt sat unanswered:wait_for_agentreturned the same pending prompt on every call, so the orchestrator could only poll or give up. It could also have answered the prompt itself:send_to_agenttyped into the card whatever its status, and the Enter after any text answers OpenCode's prompt.Cause
AgentControlService.senddid not checkneeds_approval, andwait_for_agenthad no way to wait for the person's answer.Fix
send_to_agentis refused while the subagent isneeds_approval(INVALID_REQUEST, not retryable). Nothing is written, and the refusal tells the orchestrator to tell the person what it asks and callwait_for_agentagain.wait_for_agentreturns a given prompt once. A later wait on the same prompt waits for the person's answer and then for the subagent's turn, so the orchestrator carries on in the same turn. A new prompt is reported at once again, also one that follows the last with no status change in between (see "Review fix").bashis not allowed in any new case. A decision service's deny still fails the call before OpenCode asks, its allow (from a plugin the person let allow) still answers OpenCode's prompt once, and no verdict is never turned into an allow. Person cards and OpenCode on its own model are untouched; no new UI.On main the change sits next to the newer paste/submit delivery: the refusal comes before
deliver, so a refused prompt never reaches the delivery queue. The tool descriptions keep main's 50-second client-safe wait note and plain-text screen wording;native/canvastty-helper/catalog.jsonwas regenerated withbuild-native-helpers.mjs --catalog(it matches the merged text).Test
New
tests/opencode-subagent-ask.test.mjs(2 tests). It runs the real OpenCode plugin module,RuntimeGateway,DecisionHooks,TerminalManager,AgentControlServiceandScopedOrchestrationHandler, with no OpenCode and no model: allow answers the prompt, deny fails the call, no verdict reaches Needs attention and the orchestrator,send_to_agentwrites nothing, and the person's answer resumes the subagent and the orchestrator's wait.On main without the fix, the second test fails: without the
needs_approvalchecksend_to_agentis not refused, and without the once-per-prompt rule the second wait returns the same prompt at once. With the fix both pass.Fix 5. An orchestrator could approve a Codex subagent's command through the control CLI
fix(orchestration): an orchestrator's control connection never answers a subagent's approval promptProblem
With its own control connection, an orchestrator could
choose <id> --choice 1on a Codex subagent's "Would you like to run the following command?". That approved the command for the person;dismissanswered it "No, and tell Codex what to do differently". The orchestrator skill even described these as menuschoose/dismisscan act on.Cause
choose/dismissonly checked that the menu was the one observed, not what it asks.sendwas refused there, but with a retryableNOT_READYthat said "wait".Fix
On an orchestrator's own connection (a session-scoped grant),
choose,dismissandsendgetNEEDS_PERSON, which is not retryable, writes nothing and tells the orchestrator to tell the person. Two checks, either of which refuses:needs_approval, the status each CLI's own approval signal sets (Codex, Claude Code, Qwen and KimiPermissionRequest, Grok's permission notification, Hermespre_approval_request, OpenCodepermission.asked/question.asked).chooseacts on that exact screen. So on an orchestrator's connectionchooseanddismissact only on the Codex menus known not to be approvals: hooks review (and its "hooks reviewed" notice), the model or rate-limit notice, and the update notice. Any other Codex menu is refused, including folder trust (CanvasTTY already answers it for subagents inside the project), a permissions change ("Update Model Permissions"), and an approval worded in a way CanvasTTY does not recognise. Known approval texts (command, edits, permissions, network, MCP requests) are refused even if they appear next to an allowed title.sendis also refused while a known approval is on screen; otherwise Codex's own empty-composer check already keeps text away from any menu.Unchanged: the menus listed above stay the orchestrator's;
status,screenandresultstill read;interruptstill stops its own turn (stopping is not an answer, and the asked call does not run); the person's own app-wide connection, the card's input and decision services are untouched.Remaining limit: the screen check reads the visible Codex screen, so it is only as good as that screen. If Codex were to show an approval whose text matches none of the known approval patterns and also carries an allowed title (for example "Hooks need review") on its own line, before the hook report arrives, it would be treated as that menu. Once the hook reports, the status refuses it whatever the screen says.
Test
New
tests/orchestrator-approval-answers.test.mjs(5 tests, the fifth from the review fix). It runs the realTerminalManager,AgentControlService,AgentControlGatewayand control CLI request path over a socket with an orchestrator's session grant:choose(each option),dismissandsend, and the refusal replays for the same request id instead of writing;needs_approval); folder trust and a permissions menu are refused;send_to_agentis refused at each CLI's approval signal (Claude Code, Codex, Grok, Kimi, Qwen, Hermes, OpenCode) and delivered once the person answered.The tests use main's paste-then-submit delivery (an echoing fake composer, as main's own delivery tests do), so a delivered task is checked as its paste followed by the submit key.
On main without the fix, the first
chooseon the approval prompt writes the keys (the second test fails with "Missing expected rejection"). Without only the fail-closed menu check, the same test fails at the unrecognised approval before the hook report. With the fix all pass.Review fix.
wait_for_agenttracks each approval request, not the card revisionfix(orchestration): wait_for_agent tracks each approval request, not the card revisionThe once-per-prompt rule told prompts apart by the card's revision, which is the wrong identity both ways:
PermissionRequestright after the person answered the first moves neither the status nor the revision (TerminalManager.applyProviderSignalreturns early), so the new prompt was taken for the one already reported and the next wait ran to its timeout.TerminalManagernow counts approval requests per card (approvalRequest(id)): the count advances when the card turnsneeds_approval, and on each further request hook (PermissionRequest,pre_approval_request,permission.asked,question.asked) while it stays there. Apermission_promptNotification while the card already waits is the same prompt echoed (Claude Code and Qwen send both) and does not advance it. The count is never reset, so a relaunch cannot reuse a value a wait already saw.wait_for_agentcompares that count instead of the revision. The CLIs give no per-prompt id in their hook reports (therequestIdCanvasTTY gets is the turn id), so a counter is the identity available.Test:
tests/orchestrator-approval-answers.test.mjs, "wait_for_agent reports each approval request once, a consecutive one with no status change in between too" (Claude subagent:PermissionRequest, the echoed Notification and a thread-id change do not re-report; the person answers and a secondPermissionRequestwith an unchanged revision is reported at once; that one is reported once too; a Hermes-stylepre_approval_requestis new again). Before the fix it fails at the thread-id change ("the reported prompt waits for the person"); with that step removed it fails at the consecutive request (timeoutinstead ofneeds_approval). With the fix it passes.Verification
