gcon: Skill for Claude Code

.github/skills/bubbletea-designer/SKILL.md

bubbletea-designer is a skill for Claude Code, Codex from slayer/gcon. It costs 66 tokens per session (1,698 once invoked), scanned A, original, MIT.

A design reference for building Bubble Tea terminal user interfaces, which are text-based screens that run in a command-line window. It explains how this project's views, components, forms, and navigation fit together.

In plain words
What is it for?
It is for planning resource lists, detail screens, tabs, forms, confirmations, and the messages passed between screens in the gcon application.
Why use it?
It helps developers choose a suitable view structure and follow the project's existing interface patterns instead of designing each screen from scratch.

This is slayer/gcon's own configuration. It tells Claude Code and Codex how to work on gcon itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything gcon configures →

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-designer 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 13d 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.

Bubble Tea TUI Designer (gcon Reference)

Design reference for building Bubble Tea terminal user interfaces in gcon. Provides component selection guidance, architecture patterns, and implementation examples adapted to gcon's project-specific abstractions.

When to Use This Skill

Use this reference when you need help designing, planning, or structuring new views in gcon:

Design & Planning

  • Design a new view for a GCP resource
  • Choose the right base type (TableClickDelegate, CreateViewBase, or manual)
  • Select appropriate components from gcon's component library
  • Plan message flow between views and the App router
  • Understand architecture patterns used across the codebase

Typical Questions

  • "How should I structure a new list view for GKE clusters?"
  • "What base type should I use for a resource creation form?"
  • "How do I add a detail view with tabs?"
  • "Which components do I need for an action with confirmation?"
  • "How does the three-phase message flow work?"

View Types in gcon

Type Base Type Examples
Resource list TableClickDelegate instances, disks, buckets, SQL instances, service accounts
Resource details — (manual) instance_details, network_details, sql_instance_details
Resource creation CreateViewBase snapshot_create, disk_create, image_create, service_account_create
Resource editor — (manual, complex) bucket_create (diff preview), instance_editor (labels)
Policy/read-only — (manual) iam_policy, custom_role_details

Reference Documents

references/design-patterns.md

Core architecture patterns adapted for gcon:

  1. View Interface — gcon's simplified tea.Model alternative
  2. App as Central Router — centralized message dispatch and navigation
  3. List View with TableClickDelegate — resource list pattern
  4. Creation View with CreateViewBase — form → submit → async lifecycle
  5. Three-Phase Message Flow — Selection → Request → Result
  6. Master-Detail with Tabs — tabbed resource detail views
  7. Form Flow — gcon's forms framework with sections, validators, field types
  8. Navigation — view stack, sidebar, command palette
  9. Error Handling — inline vs full error display, SetError() propagation
  10. TextInputFocusable — preventing 'q' quit during text input

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.
