A sub-agent's reply to send_message lands in the caller's own pane
tagged [sub-agent:<name>], not in the sub-agent's output. The
descriptions for wait_for_pattern, send_message, both
timer_fire_when_idle_*, and the server-instructions preamble now
spell this out, along with the canonical send_message →
timer_fire_when_idle_any → read-own-pane pattern. help('readiness')
and help('coordination') updated to match. Previously agents reached
for wait_for_pattern on the sub-agent and deadlocked until timeout
because the reply had already been delivered to their own pane.
- Add --debug[=DIR] / --profile[=DIR] flags that write run artefacts
(patterm.log, events.jsonl, per-child raw PTY captures, CPU + heap
+ goroutine pprof) to a dir without polluting stdout/stderr.
- Strengthen vendor-TUI orientation in three places (MCP
initialize.instructions, the spawn_agent tool description, and
help('spawning')) to head off codex's habits of poking the Unix
socket via perl and shelling out to launch peers — both bypass
caller identity and produce orphaned top-level tabs.
- Fix click-and-drag text selection from alt-screen TUIs. Host SGR
mouse reporting now follows the focused child's screen side
instead of being permanently armed; alt-screen TUIs that need
mouse re-enable it themselves and the toggle is forwarded.
- Move drawSidebar() off the per-PTY-chunk hot path. Long claude
session resume was paying a full sidebar rebuild for every
scrolled chunk; the chrome ticker now drains a dirty flag at 60 Hz.
- Gate the per-chunk Title() CGO poll on a containsOSC scan so
codex/ratatui's many SGR-only chunks no longer pay a CGO call each.
Classifies every running child as idle/working/thinking/permission/error
using one of three pluggable strategies (output_activity,
osc_title_stability, osc_title_status) plus optional regex promoters
applied to the tail of recent output. State and last-match reason are
exposed via MCP on ProcessInfo and get_process_status. Per-preset
configuration lives on a new preset.IdleDetection block with bundled
defaults for the first-party claude/codex/opencode presets.
OSC title plumbing is exposed as Emulator.Title(), polled from the
session pump after each emulator write so title-change activity feeds
into the classifier without an extra cgo callback.
The MCP timer surface expands to match Solo: timer_set,
timer_fire_when_idle_any/all, timer_cancel, timer_pause, timer_resume,
timer_list. timer_wait is now a thin wrapper that shares the same
manager so it shows up in timer_list while pending. Timer bodies are
delivered to the owner process through the existing
InjectAsOrchestrator path. Top-level (non-agent) callers can attach
timers to a specific process via owner_process_id; omitting it grants
universal cancel/pause/resume/list privileges.
The sidebar gains a state glyph per process row and appends a
nearest-timer indicator when one is pending or paused.
Tests: idle_test.go covers the classify() pure function across the
three strategies and regex promotion; timers_test.go covers the
manager. Harness scenarios cover output_activity, osc_title_stability,
osc_title_status, and regex promotion, plus timer_set delivery,
cancel, pause/resume, idle_any-on-transition, idle_all-pending, and
idle_all-already-satisfied. A new wait_until_mcp harness step type
polls an MCP method until an assertion holds.
Add a `lifecycle` help topic spelling out that the caller owns the
processes it spawns and should `close_process` when a sub-agent or
spawned child is no longer needed. The `spawn_agent` and `spawn_process`
descriptions advertised via `tools/list` now restate the same duty
inline (with a pointer to `help('lifecycle')`), so vendor TUIs see the
expectation at the moment they reach for the tool. The `spawning` topic
and `topics` index cross-reference the new content.
Bundles two already-staged improvements that fall in the same area:
- OnChildSpawned primes the snapshot-replay budget for new panes so
diff-based vendor TUIs come up clean without a manual Ctrl+W/Ctrl+S
refresh.
- TODO drops the three items now actioned (prompt-injection preface,
agent cleanup duty, opencode→claude view corruption) and keeps the
unicode `<?>` entry with the investigation notes.
This batches the in-flight [Unreleased] block from CHANGELOG.md into a
single commit. Highlights:
- Real MCP protocol layer (initialize / tools/list / tools/call) so
vendor MCP clients can complete the handshake against the per-PID
socket. Legacy direct-dispatch preserved for the harness.
- New mcp_injection kinds — cli_override for codex, config_env for
opencode — joining the existing env-var and config_file paths so
patterm can slot into more agents without touching their real
config or auth.
- Ctrl+A/D and Ctrl+W/S focus navigation across tabs and intra-tab
process lists, recognised in legacy / kitty CSI u / xterm
modifyOtherKeys encodings.
- Palette macros (sw / k / sp ) and reordering so open sessions
surface above spawn-new entries.
- Two-row tab bar, sidebar/tabbar/status chrome cache, viewport-wipe
on agent spawn, CR-terminated orchestrator injections, and split-
Enter PTY writes so paste-detecting TUIs see Enter as a key event.
Also fixes the bug logged in TODO: claude's Ctrl+O tool-call expansion
emits CSI 0 J, which the viewport renderer was forwarding verbatim —
wiping the sidebar to the right of the cursor and leaving the chrome
cache convinced nothing had changed. CSI 0 J and CSI 1 J are now
translated into per-row ECH sequences clamped to the viewport, same
as CSI 2 J and CSI K already were.
Agent guides (CLAUDE.md / AGENTS.md) now spell out the
TODO->CHANGELOG workflow so completed items land in the changelog
rather than as ticked entries left behind in TODO.
