Closes #1603 — AI-3941

What & why

In the desktop app, a Claude permission prompt answered in the agent's own terminal keeps its NEEDS YOU card until the agent's whole turn ends. Claude Code's PermissionRequest hook input has no tool_use_id (its hooks reference says so, and a dump of the hook's stdin on 2.1.302 confirms it), while the daemon's PostToolUse tool-settled notice keys on that id. PostToolUse does carry the same tool_name and tool_input object plus the subagent's agent_id, so the notice carries all three and the broker matches an id-less prompt by name and deep-equal input within the subagent scope the hook ran in. A completion has no per-call link to the prompt it answered, so the broker also keeps a ledger of completions each scope is owed: every settlement of a Claude prompt other than by its own report (an allow, a deny or a withdrawal here does not prove the terminal had not already let the tool run), every policy-allowed call, and every prompt still pending when the turn ends adds one; a matching notice consumes it instead of retiring anything, and only an unowed notice falls back to the oldest identical pending prompt. Owed entries lapse 30 s after their turn ends (the reporting hook times out at 5 s). A scope whose ledger overflows loses the fallback instead of forgetting an entry, and stays suspended until a turn ends with nothing discarded since, plus the same grace.

Where to look

PermissionPromptBroker.TryWithdrawTool, SettleLocked and OweLocked: a withdrawal answers a live hook with a deny, so the fallback must never take a prompt the user has not answered. Every way the ledger can lose count errs toward leaving a card until the turn's end, never toward a deny.

Verification

  • Daemon decision log since 2026-09-04: 304 prompts answered in the app, 2 withdrawn by a tool-settled notice.
  • Hook stdin dump on Claude Code 2.1.302: PermissionRequest keys are cwd, effort, hook_event_name, permission_mode, permission_suggestions, prompt_id, session_id, tool_input, tool_name, transcript_path; PreToolUse and PostToolUse add tool_use_id.
  • Live probe on a running daemon's bridge: a tool-settled notice carrying only an id left a synthetic prompt pending; a turn-end notice withdrew it and the decision log recorded withdrawn/tool_settled.
  • Each new test failed before its production change and passes after: broker 18, bridge 3, IPC 1, orchestrator glue 2, hook relay (two events plus the subagent case).
  • Full suites before the review round: app 3345 passed, 0 failed. CLI 6935 passed, 1 timing test failed under load and passes alone. Daemon 4182 passed; the 2 failures assert an env var is absent from a built ProcessStartInfo and fail only inside a hosted shell that exports it.
  • dotnet publish -c Release of kcap and kcap-daemon: no IL2026/IL3050 warnings.

📝 Walkthrough

Tool settlement notices now include tool names, inputs, and subagent IDs. The daemon uses these fields to match prompts without tool-use IDs. The broker also tracks expected Claude completion reports and applies scope-specific grace periods and ledger limits.

Changes: Tool settlement matching

Layer / File(s) Summary
Relay tool details to the daemon
src/Capacitor.Cli/Commands/Harness/ClaudeHookCommand.cs, src/Capacitor.Cli/Commands/DaemonBridgeRelay.cs, src/Capacitor.Cli.Daemon/Services/ToolSettledNotice.cs, src/Capacitor.Cli.Daemon/Services/LocalPermissionBridge.cs, test/Capacitor.Cli.Tests.Unit/Commands/Harness/ClaudeHookToolSettledRelayTests.cs, test/Capacitor.Cli.Daemon.Tests.Unit/Services/LocalPermissionBridgeToolSettledTests.cs
The hook and relay pass tool names, inputs, and subagent IDs. The local bridge validates tool names and adds tool details to attributed notices. Tests check the relayed fields and reject oversized tool names.
Track expected completions and match prompts
src/Capacitor.Cli.Daemon/Services/PermissionPromptBroker.cs, src/Capacitor.Cli.Daemon/Services/LocalPermissionBridge.cs, test/Capacitor.Cli.Daemon.Tests.Unit/Services/PermissionPromptBrokerTests.cs, test/Capacitor.Cli.Daemon.Tests.Unit/Services/LocalPermissionBridgePolicyTests.cs, test/Capacitor.Cli.Daemon.Tests.Unit/Services/PermissionIpcTests.cs
The broker tracks owed Claude completions by scope and matches eligible prompts by ID or by tool name and deeply equal input. It applies grace periods and scope limits. The bridge registers expected completions for policy-allowed calls. Tests cover matching, completion tracking, and ledger behavior.
Dispatch scoped prompt withdrawals
src/Capacitor.Cli.Daemon/Services/AgentOrchestrator.cs, test/Capacitor.Cli.Daemon.Tests.Unit/Services/AgentOrchestratorToolSettledTests.cs
The orchestrator passes tool details and subagent scope to the broker. Tests check name-and-input matching and parent-versus-subagent prompt scope.

Merge Risk: 🟡 Moderate · up to cc376

A completion for one Claude tool call can dismiss a different, still-pending permission card when identical calls report out of order. Resolve that ambiguity before merging unless the risk is explicitly accepted.

Security architecture risk: 🔵 Low · up to cc376

The change affects how completed work is matched to pending approval requests. Existing authorization checks remain, and the new withdrawal path denies rather than grants access. Duplicate or ambiguously ordered reports could close the wrong request, but production reachability of those conditions is not established.

Retained concerns

  • Medium · reliability · inferred: The new fallback identifies an invocation by scope, tool name, and input rather than a unique request identity. After notice A consumes an owed entry, replaying A can withdraw a different identical live request; when multiple pending requests match, the oldest is selected even though the notice does not identify which was terminal-answered. The result is an explicit deny and removal of that request. The producer sends once, and the test assumes FIFO answers, so neither duplicate production delivery nor out-of-order terminal answers are established. This is a conditional permission-lifecycle concern, not a verified authorization bypass.
Security review details

Security Blast Radius

  • observed — Each fallback match is constrained to the attributed agent, supplied session, and exact subagent scope. Authentication uses a shared credential rather than per-session caller identity, and attribution reads payload-supplied identifiers. A shared-credential holder already had whole-turn withdrawal authority at the PR base; that existing authority is not a newly introduced exposure.

Security Findings and Attack Paths

  • inferred — A duplicate accepted completion can consume an owed entry once and then fall through to deny an identical live request. The inspected sender performs one POST without retry, so this establishes a non-idempotent consumer transition, not evidence of routine replay or a new attacker privilege.

Trust Boundaries and Controls

  • observed — The settlement route rejects reviewer credentials and requires the shared credential. It accepts only supported vendors, bounds body reads, and requires a canonical session identifier. These controls authenticate bridge access and constrain input; they do not attest that a completion corresponds to a particular id-less invocation.

Hardening Proposals

  • proposed — Consider recording consumed completion identities where tool-use IDs are available and declining ambiguous fallback matches unless the producer's ordering contract is established. This would make permission correctness less dependent on exactly-once and FIFO delivery assumptions.

Explanation

The changed production code relays Claude tool name and input, correlates id-less prompts in the daemon, scopes matches to the subagent, and tracks owed completions to prevent incorrect fallback retirement. The added tests cover these issue-related behaviors. The changes have a direct connection to issue #1603 and do not demonstrate unrelated work.

Full details: Linked Issues check

Explanation

Issue #1603 requires id-less Claude prompt retirement in both the daemon broker and the desktop chat tab. The PR adds broker matching by tool_name and deeply equal tool_input, preserves ID matching, scopes subagent matches, and adds the owed-completion protections and tests. The whole-PR diff has no change to src/Capacitor.App/ViewModels/ChatTabViewModel.cs, and the reviewed chat-tab code still has no demonstrated matching of id-less Claude prompts against settled transcript calls at or after the card. The chat-tab coding requirement remains unmet.

Resolution

Update the desktop chat withdrawal path to match id-less Claude prompts by tool_name and deeply equal tool_input against settled transcript calls at or after the card. Retain ID-only matching for prompts with IDs. Add automated tests for this path. Keep Codex hosted prompts out of scope.

High-Level Assessment

The following are alternative approaches to this PR:

1. Use transcript correlation alone
  • ➕ Avoids extending the hook-to-daemon notice.
  • ➖ Depends on the chat tab observing transcript results; the daemon cannot promptly retire a prompt on its own.

Recommendation: Keep both withdrawal paths. The daemon can retire a prompt directly from PostToolUse, while transcript correlation covers cards that remain visible in the app. Matching identified prompts by ID and requiring comparable input for the fallback limits unrelated withdrawals.

P2 Badge Retire only one identical prompt per completed call

When multiple no-ID Claude permission requests have the same tool name and input, a single transcript result satisfies this predicate for every request raised before it, so WithdrawSettled withdraws them all. This can occur with identical parallel calls when the direct hook notice is missed, causing the still-running call's prompt to be withdrawn and effectively denied; the daemon-side matcher in PermissionPromptBroker.TryWithdrawTool avoids this by consuming only the oldest matching prompt. Pair each settled call with at most one pending invocation rather than treating it as reusable evidence.

1. Delayed server cards stay visible ✓ Resolved
Description
ShouldWithdraw compares a server request's RequestedAt against the transcript result time, but
FromServer sets that value when the app receives the server event rather than when the prompt was
raised. If that event arrives after the tool result, a matching unanswered card fails the ordering
check and remains pending.

2. Another agent's identical call denies a live prompt ✓ Resolved
Description
The new name-and-input fallback in TryWithdrawTool filters only on hosted agent and session. It
ignores the entry's SubagentId, and the Claude relay always sends the tool-settled notice with
subagentId: null. So when the main agent or one subagent finishes a call, a still-unanswered
prompt from another subagent in the same session with the same tool name and input gets settled as
withdrawn with DenyDecision. The same happens when an identical earlier call was approved in the
app: that call's PostToolUse retires the next pending identical prompt. The waiting hook then gets a
deny the user never gave.
Code

src/Capacitor.Cli.Daemon/Services/PermissionPromptBroker.cs[R111-116]

+            if (entry is null && toolName is not null && toolInput is { } input)

Evidence
Withdrawal settles with DenyDecision (line 118). WithdrawTurn shows that entries carry
SubagentId and that scoping by it matters, but the new fallback doesn't apply it. The hook relay
posts post-tool-use notices with subagentId: null, so the notice can't tell callers apart. Before
this PR, matching on the unique tool_use_id ruled out any cross-match.

Evidence
WithdrawSettled evaluates each request in _requests independently, and ShouldWithdraw returns
true for an eligible settled call without assigning it to a single card. The per-request withdrawal
guard does not reserve the settled call, so the next identical request can match it too; unlike the
broker’s one-to-one handling, the chat tab can withdraw both cards for one notice.

Add tests for the reset and switch paths and for multi-match behavior.

The test covers the main match cases. It does not cover _settledCalls.Clear() on a feed switch or reset. A missing clear would leave an old call that withdraws a card for a new transcript. The test also has no case for two identical cards and one settled call.

Claude's PermissionRequest hook carries no tool_use_id, so the id both withdraw paths keyed on was never on the prompt. PostToolUse carries the same tool_input object, the one key present on both sides.

A completion notice carries no per-call link to the prompt it answered, so an allowed call's late report could pass for the terminal answer to a newer identical prompt and deny a live hook. The ledger of owed completions and the subagent scope keep the match to the call the user answered; the app's own name-and-input match had the same ambiguity with less to go on, so the daemon decides alone.

- Around line 121-125: Update the owed-call matching in PermissionPromptBroker
so identical tool name and input do not let FindIndex assign an unordered
completion to a specific owed call. Treat multiple matching entries as ambiguous
and avoid consuming either, or use a per-call correlation value shared by the
completion and prompt paths; preserve existing matching behavior when the call
is unambiguous.

Stop is not proof that every completion report has landed: the reporting hook is asynchronous, and the app withdraws on transcript evidence ahead of it. Forgetting an owed report would let it pass for a terminal answer and deny a live hook, so the ledger lapses on a grace period, an overflowing scope suspends the fallback, and only Claude's allows are recorded.

A prompt still pending at Stop may have been allowed in the terminal with its report overtaken by Stop, and a call allowed while its scope is suspended reports on its own clock, not the earlier turn's. Both are completions the ledger must not forget while the fallback can still act on them.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The terminal can answer a prompt the daemon still shows, so a deny or a withdrawal settled here does not prove the tool never ran; only the completion report itself settles without owing one.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
A gone agent reports nothing more and ends no more turns, so an entry owed on its behalf could neither be collected nor lapse and would outlive the agent in the broker.

Superseded by #1606, which merged the same fix first. The one property this branch had that #1606 lacks, owing a call's report on every settlement of a Claude prompt rather than only on an allow, follows in a small PR on current main.
