feat(chat): show why Claude asks for approval in Full access - #9574
The approval card now shows the reason Claude Code gives for a prompt, and says when it asked even though the chat is in Full access.
The native claude-code harness now shows AskUserQuestion as a question form instead of a yes/no "Allow this tool call?" prompt.
The Full access mode description changes from "Never asks before acting" to "Rarely asks before acting".
Why / Context
Claude Code still asks before some actions in bypassPermissions mode (safety checks, ask rules). It sends a reason, but we dropped it, so a prompt in Full access looked like the mode had failed. The mode picker also promised it would never ask.
How It Works
Protocol:approvalRequestSchema gets an optional reason. It is a looseObject, so released clients ignore it.
ACP (claude-acp): claude-agent-acp sends the reason only to JetBrains AIR clients, at _meta.jetbrains.air.permission.description (prefixed with Reason: ). We already advertise AIR in initialize, so airPermissionReason() reads it from there. codex-acp sends the same field without the prefix.
Native (claude-code):canUseTool passes decisionReason through, trimmed. AskUserQuestion now becomes a form with one field per question plus a <id>_custom "Other" field, the same shape claude-agent-acp builds, so QuestionForm renders it. Answers fold back into the tool input the way Claude Code's call() reads them: multi-select picks are comma-joined and quoted, and text typed beside a single-select pick goes into annotations[question].notes. Skip lets the tool run with no answers; cancel interrupts the turn.
Desktop: a new SessionModeProvider gives ApprovalRow the chat's mode. A new ApprovalReason box shows the reason. In an unrestricted mode it adds the heading "Still asks in Full access mode", and falls back to a generic note when there is no reason. It shows only on pending option cards, never on forms or answered cards.
Manual QA Checklist
Not done yet: this was written in a cloud workspace that can't run Electron.
Full access Claude chat: a prompt Claude still raises (for example a long $(...) chain that sends a login code) shows the reason box with "Still asks in Full access mode"
"Ask for approval" mode: a prompt shows the reason without the heading, and looks the same as before when there is no reason
Old claude-code chat: AskUserQuestion renders as a question form; picks, "Other" text and Skip all reach Claude
Mode picker shows "Rarely asks before acting" for Full access
Answered and expired approval cards look the same as before
Testing
bun test in packages/chat-runtime (506 pass, 2 skip), packages/chat (120), apps/desktopsrc/renderer/routes/_authenticated (2536), packages/host-servicesrc/chat-v3 (100)
New tests: AIR reason parsing, ACP approval reason, native decisionReason, native AskUserQuestion form round trip, answer folding (multi-select quoting, single-select notes)
bunx tsc --noEmit in packages/chat-runtime and apps/desktop
bunx biome check, bun run check:i18n (2 new strings plus the changed mode description, translated in all 17 locales)
Not run locally: the repo-wide bun run typecheck / bun run lint / sherif; CI covers those.
Known Limitations
claude-agent-acp's code calls the reason field temporary diagnostic text, so an adapter bump may change or drop it. The card then falls back to the generic note.
Mobile (ChatRowView) does not show the reason yet.
The note follows the chat's current mode, not the mode when Claude asked.
Agents other than Claude that ask a question as an options prompt, rather than a form, still get the generic Full access note.
Summary by cubic
Shows the reason Claude Code gives when it asks for approval, so prompts in Full access no longer look like the mode failed. Claude Code still asks before some actions in bypassPermissions mode (safety checks, ask rules), and the card previously dropped the reason. The native claude-code harness now renders AskUserQuestion as a question form instead of a yes/no "Allow this tool call?" prompt.
Approval items carry an optional reason: the ACP adapter reads it from _meta.jetbrains.air.permission.description, and the native harness passes decisionReason through.
The desktop approval card shows the reason with a "Still asks in Full access mode" heading in unrestricted modes, or a generic note when no reason was sent.
The Full access mode description now reads "Rarely asks before acting".
AskUserQuestion forms get one field per question plus an "Other" text field; answers fold back into the tool input, and Skip lets the tool run with no answers.
Written for commit 56af755. Summary will update on new commits.
Summary by CodeRabbit
New Features
Approval prompts can now explain why an action needs permission, including prompts that remain in Full access mode.
Claude’s question requests are presented as interactive forms, with submitted answers passed back to the agent.
Updates
Full access is now described as rarely asking before acting, rather than never asking. Approval guidance is available in supported languages.
Claude Code still raises some approval prompts in bypassPermissions
mode (safety checks, ask rules). The card gave no reason, so it looked
as if Full access had failed.
- Approval items carry an optional `reason`. The ACP adapter reads it
from `_meta.jetbrains.air.permission.description`, which
claude-agent-acp sends to AIR clients (we already advertise AIR).
The native Claude adapter passes `decisionReason` through, trimmed.
- The desktop approval card shows the reason, with a "Still asks in
Full access mode" heading when the chat is in an unrestricted mode,
and a generic note when no reason was sent.
- The Full access mode description no longer claims it never asks.
- The native claude-code harness now asks AskUserQuestion as a form,
like claude-agent-acp does, instead of a yes/no tool approval.
Answers fold back into the tool input as Claude Code's call() reads
them. A skip still lets the tool run with no answers, so the model
hears the user passed instead of the turn failing.
Approval requests can include reasons from ACP and Claude adapters. Claude AskUserQuestion requests use forms to collect answers. The desktop transcript displays approval context and mode-specific labels. Full access descriptions and translations now state that some actions still prompt.

Summary
Approval reason contract and ACP support packages/chat/src/protocol/items.ts, packages/chat-runtime/src/harness/acp/...
Approval requests accept an optional reason. The ACP adapter extracts AIR permission descriptions, removes a leading Reason: prefix, and includes the resulting text when available. Tests cover extraction and adapter output.
Claude reasons and question forms packages/chat-runtime/src/harness/claude/askUserQuestion/*, packages/chat-runtime/src/harness/claude/claudeAdapter/*
The Claude adapter retains decision reasons and emits them with approval requests. It builds forms for valid AskUserQuestion input and converts submitted values into tool answers. Cancellation denies and interrupts the tool request. Tests cover reason propagation and form responses.
Transcript approval details and mode copy apps/desktop/src/renderer/routes/_authenticated/_dashboard/v2-workspace/$workspaceId/hooks/usePaneRegistry/components/ChatSession/..., apps/desktop/src/renderer/routes/_authenticated/components/AgentComposer/utils/modeCopy/modeCopy.ts, packages/i18n/locales/*/messages.po
The transcript receives the session mode and displays approval reasons, fallback text, and a Full access label when applicable. Mode descriptions and locale catalogs replace “Never asks before acting” with wording that describes rare prompts and approvals that still occur.
No actionable issue remains from this review; the change is mergeable after normal checks.

Review: minor issues. The approach is sound and backward compatible, CI is green, and the card states render as described. Three small points:
packages/chat-runtime/src/harness/claude/claudeAdapter/claudeAdapter.ts:536: no test covers AskUserQuestion Skip (decline → allow with answers: {}) or cancel (interrupt). This is the only approval where "decline" lets the tool run, and it is the only button on mobile.
packages/chat-runtime/src/harness/claude/claudeAdapter/claudeAdapter.ts:491: the native decisionReason has no length cap (claude-agent-acp caps the same text at 4,000 chars), and ApprovalReason.tsx:20 has no max height. A long reason pushes Deny/Allow down.
packages/chat-runtime/src/harness/claude/askUserQuestion/askUserQuestion.ts:35: near-verbatim port of claude-agent-acp's elicitation.js answer folding. The logic matches today; a parity test against the upstream function would catch drift.
Questions: does native decisionReason also fill ordinary asks in "Ask for approval" mode? Does codex-acp send the same text in both description and the AIR meta (it would then show twice)?
Evidence: the PR's components, mounted in the running desktop renderer (component-level, not a live Claude prompt). Tests, tsc and check:i18n pass locally.
