kb: Skill for Claude Code

.agents/skills/bubbletea/SKILL.md

bubbletea is a skill for Claude Code, Codex from compozy/kb. It costs 46 tokens per session (474 once invoked), scanned A, original, MIT.

Guidance for building interactive terminal user interfaces in Go with Bubble Tea, a Go framework for text-based screens. It covers layouts, keyboard and mouse input, state updates, and terminal-safe text handling.

In plain words
What is it for?
Use it to add or review Bubble Tea screens, widgets, resizing behaviour, focus handling, keyboard or mouse controls, and model-update-view code.
Why use it?
It helps avoid broken layouts, incorrect hit areas, clipped text, and rendering code that performs side effects. It also accounts for different terminal sizes and installed framework versions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bubbletea scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 25d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 33 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bubble Tea TUI Development

Work with the repository's installed Bubble Tea/Lip Gloss versions and existing model/update/view structure. Use current official docs for version-specific API changes; do not assume bundled examples match the consuming project's major version.

Implementation

  • Reuse nearby components and state ownership. A small widget does not require a new project scaffold, YAML configuration, hot reload, mouse handling, or effects library.
  • Before changing layout, inspect the relevant guidance in references/golden-rules.md. Measure the actual frame/padding and clamp small-terminal dimensions; subtracting a fixed two cells is valid only for that exact border.
  • Use terminal-cell/ANSI-aware measurement and truncation. Do not slice strings by byte length or assume code points equal display width. Choose clipping, wrapping, or scrolling for the content's behavior; not all bordered text must truncate.
  • Keep hit-testing consistent with the rendered layout and focus state. Proportional sizing is useful for flexible panes; fixed sizes are valid for intentional controls.
  • Keep effectful work outside rendering and preserve the model/update lifecycle. Validate the changed interaction and relevant narrow/wide terminal sizes; add an owning test only when behavior lacks coverage.

Bundled templates are optional starting points for a new application. Adapt their API versions and layout assumptions; do not replace a working project structure or add dependencies it does not need. Install required dependencies through the repository's package workflow, not by hand-editing go.mod. Product behavior, terminal constraints, and project conventions take precedence over illustrative examples.

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
