patterm/TODO.md

• We should probably rename the Kill terminology to Close instead, across processes and agents.
• Exited shells are still being treated as active processes. They should be removed from the process list when they exit.
• Shells should be renamed to terminals. "New Terminal" etc.
• Codex seemed to think that it needed to launch patterm itself to get the mcp working
• I cant click and drag to select text from codex
• codex uses perl to interact with the socket rather than calling mcp tools
  • when it did open a sub claude it opened it as a separate tab rather than a sub-agent.
• codex rendering is VERY slow
  • maybe we need to use diffing rather than rendering the entire viewport for performance
• We should add a --debug and --profile flag, so we can get detailed performance data and full logs of the agent output to be debugged later on.
  • I don't mind what format this is in, ideally easy for LLMs to understand
• Resuming a long claude session takes a couple of seconds for the entire buffer to load in, it looks like it's scrolling down for a couple seconds.
  • In raw alacritty this is instant, so there's some sort of performance issue with patterm's terminal emulation.

On Hold

• There's a unicode being displayed in opencode [ON HOLD]
  • Investigated 2026-05-14: patterm passes ghostty grapheme codepoints through unchanged (vt/ghostty.go:452-462), so the <?> glyph is most likely the host terminal's font fallback for opencode's Nerd Font private-use codepoints, not a patterm substitution. Need a concrete reproduction (which codepoint, which host terminal/font) before changing rendering.
• After codex rips for like 15 minutes, the terminal becomes quite slow. [ON HOLD / VERIFYING]
  • 2026-05-14: Perf plan P1-P11 landed (see CHANGELOG). Needs a real long-running codex session to confirm whether the steady-state slowdown is gone or some hotspot remains. Capture a pprof if it still feels slow after ≥15 minutes — the structural drivers the audit named are all addressed, so a remaining symptom is a new one and probably wants fresh profiling.
