From 4e78259e5d6e129ec36dbab5186f26f526398032 Mon Sep 17 00:00:00 2001 From: Bharath Mohan <2254476+bharathm03@users.noreply.github.com> Date: Tue, 1 Sep 2026 17:38:09 +0530 Subject: [PATCH 1/2] Handler: submit the line it types, and ask the agent before answering for it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A PTY auto-reply was one write of text + CR. A coding-agent TUI tokenizes a read as a whole — Claude Code emits a control character as its own key event only while the read is under 64 characters — so every reply at or above that landed in the composer as literal text and was never sent. The engine banked the transition anyway, so the session rested at watching with the prompt stranded and no turn-end coming. Submitting now goes through TerminalSession.submit: the line, a gap, then the CR in a read of its own, serialized per terminal so a keystroke cannot land inside it. A bare slash verb is padded with one space, which clears the suggestion list that would otherwise route Enter to accept rather than submit. The same seam covers terminal:input, so an escalation chip — up to 400 characters — no longer types without submitting while the card latches disabled and both sides drop the row. onUserReply gated on isSubmitKeystroke. It reset the runaway guard on every inbound byte, and once an agent enables mouse tracking every pointer event is one of those, so moving the mouse bought an unbounded auto-reply budget. The CR/LF test it used also matched alt+enter and a paste's interior newlines, retiring escalations while the agent stayed blocked. The predicates move to keystrokes.ts, a leaf both agent-core and the handler can import. buildDecidePrompt gains the move it was missing: ask the agent when information is missing, rather than assuming and writing a recipe. The agent holds the live session and the working tree; the judge reads a bounded excerpt. Ordered after the escalate rule so a question cannot divert what belongs to the human. replyShape flattens the slash-command argument tail the way it already flattened reply, and names the field it actually refused — the reason is fed verbatim to the one retry, so it was teaching the judge to edit the field it got right. The destructive floor learns the outward moves: gh pr merge/close, gh release/repo delete, forced branch delete, git tag -d, npm publish. Advisory, never HARD — merging the pull request is routinely the backlog's whole point. Nothing snapshots them, so they report that no undo exists instead of passing in silence. --- bridge/src/agent-core.ts | 73 ++---- bridge/src/handler/authorization.ts | 55 ++++- bridge/src/handler/config.ts | 34 ++- bridge/src/handler/decision.ts | 18 +- bridge/src/handler/destructive-floor.ts | 17 ++ bridge/src/handler/engine.ts | 121 +++++++-- bridge/src/handler/judge.ts | 14 +- bridge/src/handler/reply-shape.ts | 43 +++- bridge/src/handler/runaway-guard.ts | 5 +- bridge/src/handler/session-adapter.ts | 11 +- bridge/src/handler/snapshot.ts | 29 +++ bridge/src/keystrokes.ts | 72 ++++++ bridge/src/pty-submit.ts | 93 +++++++ bridge/src/session-manager.ts | 7 +- bridge/src/terminal-manager.ts | 9 + bridge/src/terminal-session.ts | 31 ++- bridge/src/work-status.ts | 5 +- bridge/tests/handler/authorization.test.ts | 24 +- bridge/tests/handler/config.test.ts | 45 +++- bridge/tests/handler/decision.test.ts | 56 +++++ .../tests/handler/destructive-floor.test.ts | 29 +++ bridge/tests/handler/engine.test.ts | 233 +++++++++++++++++- bridge/tests/handler/judge.test.ts | 13 +- bridge/tests/handler/reply-shape.test.ts | 37 ++- bridge/tests/handler/session-adapter.test.ts | 9 +- bridge/tests/handler/snapshot.test.ts | 19 +- bridge/tests/pty-submit.test.ts | 110 +++++++++ bridge/tests/submit-keystroke.test.ts | 27 +- bridge/tests/work-status.test.ts | 2 +- 29 files changed, 1111 insertions(+), 130 deletions(-) create mode 100644 bridge/src/keystrokes.ts create mode 100644 bridge/src/pty-submit.ts create mode 100644 bridge/tests/pty-submit.test.ts diff --git a/bridge/src/agent-core.ts b/bridge/src/agent-core.ts index 74c37a68..eb9c334d 100644 --- a/bridge/src/agent-core.ts +++ b/bridge/src/agent-core.ts @@ -7,6 +7,12 @@ import { logger } from "./logger"; const log = logger.child({ component: "agent-core" }); import { TerminalManager } from "./terminal-manager"; import { createKeyedLock } from "./keyed-lock"; +import { + hasTypedContent, + isInterruptKeystroke, + isSubmitKeystroke, + submittedLine, +} from "./keystrokes"; import { AGENT_GRACE_MS, killChildTree, processGroupSpawn } from "./terminal-session"; import { createConnState, type ConnState } from "./conn-state"; import { FileWatcher } from "./file-watcher"; @@ -154,53 +160,6 @@ export function buildChatSpawnAugment( }; } -/** - * Whether a `terminal:input` payload submitted a prompt, for the work-status - * turn inference agents without a pre-turn hook depend on (see work-status.ts). - * - * A TUI submits on CR, so that's the signal — but only as the FINAL byte, and - * never behind ESC: `\x1b\r` is alt+enter, which inserts a newline into a - * multi-line prompt rather than sending it.

The floor additions had two defects that matter: `gh pr (merge|close)` and `gh (release|repo) delete` were each one regex over two operations, and §5.4 keys an authorization lift on the pattern SOURCE — so "close the stale PRs" granted every merge, and an authorized release delete authorized deleting the repository. Split one operation per pattern. PR_ANCHOR accepted a bare `#42`, but GitHub numbers issues and pull requests in one series, so "closes #42 once the fix lands" — a backlog line about an issue — granted a session-wide gh pr close. The bare arm is gone; "PR #42" still anchors. The merge alias also matched "fix the merge conflicts on PR #12", which asks for the opposite of a merge. The git branch flags had no option-token boundary, so `-perf` in a branch name read as a force and flagged the safe `git branch -d`, while the grouped spellings `-fd` and `-Dr` matched nothing. git tag scanned past quotes and separators, so `-m "fix -d flag"` read as a tag deletion. Publish flagged --dry-run and knew only npm, not the pnpm/yarn/bun this repo actually uses. The capability responder wrote straight to the PTY, the one writer that could land between an injected line and its deferred CR — the interleave the queue exists to prevent. It goes through the queue, which is a pass-through whenever no submit is in flight. The queue opened a gap before the CR but not after, so the next write joined the CR's read and robbed it of its key event one step later than the bug this fixes. padBareVerb treated an absolute path as a slash verb. hasTypedContent counted the terminal's own mouse and focus reports as typed content, and typedSessions outlives the frame that set it — so one pointer move made the next bare Enter open a turn no stop hook would close, on the same premise the previous commit acted on for onUserReply. The judge's onTimeout fired on one of the three legs that spend the budget, staying silent on an exhausted budget and a hung retry — the two that most need naming. The wrap-up push put the expiring undo offer last, behind an unbounded summary, in a string OS surfaces truncate. --- bridge/CLAUDE.md | 4 +- bridge/src/handler/authorization.ts | 23 +++++-- bridge/src/handler/config.ts | 11 ++-- bridge/src/handler/destructive-floor.ts | 31 +++++++-- bridge/src/handler/engine.ts | 6 +- bridge/src/handler/judge.ts | 9 ++- bridge/src/handler/snapshot.ts | 19 +++--- bridge/src/keystrokes.ts | 20 +++++- bridge/src/pty-submit.ts | 13 +++- bridge/src/terminal-session.ts | 12 ++-- bridge/tests/handler/authorization.test.ts | 27 ++++++++ .../tests/handler/destructive-floor.test.ts | 65 +++++++++++++++++++ bridge/tests/handler/judge.test.ts | 29 +++++++++ bridge/tests/pty-submit.test.ts | 45 +++++++++++++ bridge/tests/submit-keystroke.test.ts | 29 +++++++++ 15 files changed, 307 insertions(+), 36 deletions(-) diff --git a/bridge/CLAUDE.md b/bridge/CLAUDE.md index bf7d1a20..181b9d63 100644 --- a/bridge/CLAUDE.md +++ b/bridge/CLAUDE.md @@ -143,9 +143,9 @@ already has them. - `/turn-start` hook (Claude only) → `turnStart`: clears the block AND opens a turn. - chat resolve (`agent:permission-resolve`/`-question-resolve`) → `answerRequest`: same, but ONLY if something was actually pending — a resolve racing a retraction would otherwise open a turn no turn-end closes. - bare PTY keystroke → `userReply`: clears the block only.
