What it does

Tui Render Debug is an agent skill from dimetron/pi-go. Diagnose and fix pi-go TUI rendering corruption, especially displaced panels, stale rows, cursor drift, and terminal-specific ANSI incompatibilities.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Go implementation of AI coding agent. The licence is MIT.

Example prompts

  • “/tui-render-debug”

What it can do on your machine

Read from SKILL.md and the folder at commit 24d1f2b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • rg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tui Render Debug loads about 783 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 414 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~783

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

TUI Render Debugging

Use this skill when pi-go's Bubble Tea interface is broken in a terminal: text appears in the wrong row or column, the sidebar moves, old frames remain after a resize, or a redraw repairs the display.

Establish the symptom

Capture the exact terminal, TERM, COLORTERM, TERMINAL_EMULATOR, terminal size, and whether a full redraw or switching terminal modes repairs the frame. Compare the broken frame with the next clean frame. A clean redraw after a bad incremental frame points to renderer cursor state, not necessarily to bad View() geometry.

For JetBrains IDE terminals, record TERMINAL_EMULATOR=JetBrains-JediTerm. JediTerm can report TERM=xterm-256color while mishandling cursor-backward-tab (CSI Z, CBT), which makes Bubble Tea's differential renderer believe the cursor is in a different column than the emulator.

Separate output leaks from renderer drift

The interactive TUI owns the terminal. Search the active path for direct output:

bash
rg -n 'fmt\.Print|log\.Print|os\.(Stdout|Stderr)|slog\.' internal cmd

Routine diagnostics must use the session logger. User-facing notices must use the TUI message or notice channel. A subprocess's stdout and stderr must be captured and surfaced as a tool result. Direct writes can move the cursor, but the absence of leaked stderr does not rule out a renderer incompatibility.

Build a red-capable repro

Use a PTY with the affected environment and capture stdout and stderr separately. Count and inspect control sequences in stdout; stderr should contain only diagnostics expected outside the frame.

For renderer-level tests, create an ultraviolet.TerminalRenderer with the affected environment, move from a later column to an earlier column, and assert that unsupported CBT is not emitted. Replay the captured bytes through a JediTerm-compatible emulator when available. Also verify ordinary xterm and tmux/screen environments remain unchanged.

Fix decisions

Keep frame geometry tests independent: every rendered row must match the terminal width, the rail must stay in one display column, and no ANSI escape may leak into visible content. Do not solve a terminal capability bug by changing layout constants.

When the Bubble Tea dependency has no per-capability switch, isolate a compatibility environment to Bubble Tea's renderer. Preserve the original environment for subprocesses and use the original environment for color-profile detection. Prefer disabling only the broken capability when the dependency supports it; otherwise use the narrowest compatible renderer profile and add a comment explaining why.

Verification

Run the focused regression test first, then the full TUI package, race tests for the affected seam, golangci-lint run ./internal/tui/..., and a build. Re-run the PTY capture and confirm the affected terminal no longer drifts while normal terminal output and colors remain intact.
