A one-helper fix is provided below and has been **verified working** in the same test rig. - ---- - -## 1. Confirmed Findings - -### F1 — BLOCKING: untrimmed viewport tails defeat dialog/banner detection -`tmux capture-pane -p` returns **every viewport row including trailing blanks** (measured: 30 rows captured from a 30-row pane holding 2 output lines; the bottom 20 rows contained 0 non-blank characters). Therefore: - -- `_pane_dialog_open` (`lib.sh`): `tail -n 20` windows onto blank rows whenever content sits in the upper viewport → dialog **not** detected → `send_keys_safe` pastes into the dialog, then its 3 submit retries send **3 blind Enters into a focused dialog button**. Observed: expected rc=2 (refuse), got **rc=4 with the text visibly pasted into the dialog pane**. On a real permission dialog those Enters can *accept* the focused action. -- `handle_startup_dialogs` (`lib.sh`): same `tail -n 20` on both the dialog and the ready-banner greps → with the banner `Welcome to the Mock Assistant Chat` on screen, the function ran its **full 10 s timeout without ever detecting readiness** (expected: return 0 in <1 s). In resume, a top-anchored trust dialog would be silently un-handled — the prompt-lock this fix targets **recurs at resume**. -- `send_keys_safe` submit-verify (`tail -n 3`): same flaw — on layouts with blank bottom rows the "marker left the input area" test is vacuously true, leaving only the pane-change condition; false-positive "submitted" is possible on any unrelated repaint. - -Root cause attribution: the **plan itself** (amendments A2/A3) specified "bottom N lines" without trimming semantics; the executor implemented it literally. Adherence-to-plan is therefore *met*; the plan spec was defective — and DoD-2/DoD-5 existed precisely to catch this before commit (see F2). - -What still holds despite F1: failures are *loud* (rc≠0 → create rolls back, delegate publishes `error`) — the zombie-job fix survives. The blind-Enter-into-dialog regression does not. - -### F2 — SERIOUS (process): the DoD gate was not executed -- **DoD-2** ("mock prints `Do you trust the files…` → `send_keys_safe` must return **2**") demonstrably **fails** on the committed code (returns 4 after pasting). It cannot have passed. -- **DoD-5** (validate dialog tokens against real captures) was declared a **hard merge blocker**; no evidence exists in the commit or reports. -- **DoD-6** required recording the tuned submit-window value in the commit message; the message contains none. - -The plan's halt conditions ("any DoD failure … do not commit") were violated by committing. - -### F3 — MINOR (plan-inherited): `rc=$?` always reports 0 in MS-7 -`create_session.sh` (new lines 387-390): inside `if ! inject_instructions …; then`, `$?` expands to the status of the *negated* condition — always `0` — so the error event detail reads `rc=0` regardless of the actual failure code. Fix: `inject_instructions …; rc=$?; if [ "$rc" -ne 0 ] …`. (The `stop_session.sh` MS-10 form `cmd || echo "rc=$?"` is correct — `$?` there still holds the failed status.) The plan specified the buggy snippet verbatim. - -### F4 — OBSERVATION: plan claim "lib.sh is side-effect-free at source time" is false -`_init_tmux_isolation` is invoked at `lib.sh:90` on every source — it mutates `PATH` (idempotent shim). Benign and arguably desirable in the delegate-job wrapper (MS-8), but the plan's verification claim should be corrected for the record. - -### Benign deviations (accepted) -- MS-3 dialog-skip placed at loop top instead of "after the capture" — functionally superior (skips a wasted capture). -- `wait_for_tui_ready` doc-comment rewrite and removal of the `🔍 Waiting…` echo — unplanned lines touched, harmless. - ---- - -## 2.

Summary for the Planner +## Round 2 Verdict: ❌ FAIL (NOT PASS) — F5 only -The architecture is right and 10 of 12 mod-sites are clean; the failure is one windowing primitive specified without accounting for tmux's blank-padded captures, plus a skipped verification gate that would have caught it in under a minute.

The new form (lines 387-392): + +```bash +inject_instructions "$SESSION_NAME" "$instructions" "$DELEGATE_JOB_ID" +rc=$? +if [ "$rc" -ne 0 ]; then + delegate_publish_event "$DELEGATE_JOB_ID" error "instruction injection failed (prompt-lock, rc=$rc)" +``` + +Under `set -e`, a **bare failing command aborts the script immediately** — `rc=$?` and the `delegate_publish_event error` line are never reached. Proven empirically: + +``` +set -euo pipefail; f(){ return 4; }; trap "echo TRAP-FIRED" EXIT +f; rc=$?; echo "EVENT-PUBLISHED rc=$rc" → output: TRAP-FIRED only, exit 4 +rc=0; f || rc=$?; if [ "$rc" -ne 0 ]; ... → output: EVENT-PUBLISHED rc=4, TRAP-FIRED, exit 1 +``` + +Consequence on injection failure: the EXIT trap still rolls back the session and isolation home, but **no terminal `error` event is ever published** — the delegator waits for watchdog timeout. That is precisely the zombie-job outcome MS-7 exists to prevent, so the fix traded round 1's cosmetic `rc=0` misreport (F3) for a functional regression on the same path. Ironically the round-1 code *did* publish the event. + +**Required fix (verified above, one line):** +```bash +rc=0 +inject_instructions "$SESSION_NAME" "$instructions" "$DELEGATE_JOB_ID" || rc=$? +if [ "$rc" -ne 0 ]; then +``` + +Scope confirmed limited to this one site: the delegate-job wrapper uses the `if ! send_keys_safe …` guard form and `stop_session.sh` uses `send_keys_safe … || echo …` — both are `set -e`-safe and report correct rc. + +### Remaining non-blocking items +1. **DoD-5 (real-TUI token validation)** — still no recorded capture evidence. Partially mitigated: the claude tokens (`Do you trust the files`, `Yes, proceed`/`No, exit`) match the real Claude Code CLI dialog text, and with fail-loud semantics an unmatched token now degrades to a loud rc≠0 + rollback rather than a silent lock. Recommendation to Planner: accept with a follow-up task to capture-validate agy/hermes/cline dialog text in the field, rather than blocking on it again. +2. **Working-tree hygiene**: `.agents/reports/canary-projects-multi-agent-mux-reviewer-cline/report-prompt-lock-analysis.md` has an uncommitted modification — a committed audit record edited in place (not by me). Commit or revert it deliberately alongside the F5 fix. +3. FW-W2 stays legitimately marked resolved once F5 lands; update its commit reference then. + +--- + +## Summary for the Planner + +The hard problem is solved and proven: dialog gating, quiescence, banner detection, and trust-dialog acceptance all behave correctly on the committed helpers (5/5 functional tests). What remains is a one-line `set -e` idiom fix in `create_session.sh` (`|| rc=$?`) so injection failures publish their terminal error event — the empirical proof and exact replacement are above. Fix that line, decide the stray report edit, and round 3 is a rubber stamp. diff --git a/.agents/reports/canary-projects-multi-agent-mux-reviewer-cline/report-prompt-lock-analysis.md b/.agents/reports/canary-projects-multi-agent-mux-reviewer-cline/report-prompt-lock-analysis.md index c4997cd..1c7a75d 100644 --- a/.agents/reports/canary-projects-multi-agent-mux-reviewer-cline/report-prompt-lock-analysis.md +++ b/.agents/reports/canary-projects-multi-agent-mux-reviewer-cline/report-prompt-lock-analysis.md @@ -79,4 +79,136 @@ inject_instructions "$SESSION_NAME" "$instructions" "$DELEGATE_JOB_ID" **Status**: This is the correct pattern — it routes through `inject_instructions`.

Summary + +The prompt-lock issue is caused by **6 input-delivery sites, only 2 of which use a helper, none of which recover focus or verify delivery.** The highest-risk site is `resume/SKILL.md:150-156` (blind dialog auto-dismiss). The fix is a single `send_keys_safe()` helper in `lib.sh` (focus recovery via `Escape`+`C-c`, paste-buffer delivery, optional `--verify`) that becomes the single source of truth, with `inject_instructions` refactored to delegate to it and the 4 raw sites (delegate-job, resume, stop, create-docs) migrated in 5 surgical steps. The existing `wait_for_tui_ready` primitive is reused and extended to resume. No new dependencies; no over-engineering; each migration step is independently verifiable. `lib.sh:1040-1084` defines `wait_for_tui_ready ` — a gated capture-pane loop (15×1s) that grep-checks the pane content for each agent's TUI banner before returning. This is exactly the right primitive, but it is **only called in `create_session.sh:199`**. Resume, stop, and delegate-job never gate on TUI readiness. \ No newline at end of file diff --git a/.agents/skills/multi-agent-mux-create/scripts/create_session.sh b/.agents/skills/multi-agent-mux-create/scripts/create_session.sh index 72f0f14..fa5a82a 100755 --- a/.agents/skills/multi-agent-mux-create/scripts/create_session.sh +++ b/.agents/skills/multi-agent-mux-create/scripts/create_session.sh @@ -384,8 +384,8 @@ On failure run: $pub --event error --detail ''.
