Agent Devtools UX Set

My personal AI Agent devtools/dev UX set.

Skills Catalog

Custom skills for Claude Code that extend its capabilities.

Skill	Description	Trigger Examples
interview	Socratic interviewer for requirements elicitation. Probes blind spots, challenges assumptions, synthesizes understanding.	/interview auth system, "help me think through this feature", vague requirements
lazy-skill	On-demand skill loader to reduce context bloat. Browse and load skills from ~/.claude/lazy-skills/ only when needed.	/lazy-skill, /lazy-skill docker
mattermost-cli	Fetch and search Mattermost messages. Auto-redacts secrets for safe LLM processing. Maintained in its own repo.	"check my messages", "what did alice say about X", /mattermost

Installation

# Skills from this repo
bunx skills@latest add ardasevinc/agent-devtools --skill <skill-name>

# mattermost-cli is maintained separately
bunx skills@latest add ardasevinc/mattermost-cli --skill mattermost-cli
bun i -g mattermost-cli  # also requires the CLI tool (npm/pnpm also work)

# Symlink to Claude config
ln -sf /path/to/agent-devtools/claudecode/statusline.ts ~/.claude/statusline.ts

# Add to ~/.claude/settings.json

{
  "statusLine": {
    "type": "command",
    "command": "bun ~/.claude/statusline.ts",
    "padding": 0
  }
}

Task List Picker

Interactive fzf picker to browse and resume Claude Code sessions by their task lists. Launches Claude with CLAUDE_CODE_TASK_LIST_ID set, enabling task sharing/resumption across sessions.

agent-devtools (3 tasks) - 2h ago    │ ✓ Add skills catalog to README
vyvo-app (12 tasks) - 1d ago         │ → Implement auth flow
mattermost-cli (5 tasks) - 3d ago    │ ○ Add rate limiting

Setup

Requires Bun and fzf.

# Add to PATH
ln -sf /path/to/agent-devtools/claudecode/claude-tasks.ts ~/.local/bin/claude-tasks

# Make executable
chmod +x ~/.local/bin/claude-tasks

Usage

claude-tasks              # Pick a task list, launches claude
claude-tasks --resume     # Pass flags through to claude

Features

• Project detection: Resolves project path from session files
• Task preview: Shows tasks with status (✓ done, → in progress, ○ pending)
• Recency sorting: Most recent sessions first
• Seamless launch: Opens Claude in the correct directory with task context

Lazy Skill System

Reduce context bloat by loading skills on-demand instead of always injecting them. Skills in ~/.claude/lazy-skills/ are only read when you invoke /lazy-skill.

Setup

# Create the lazy skills directory
mkdir -p ~/.claude/lazy-skills

# Install the meta-skill
bunx skills@latest add ardasevinc/agent-devtools --skill lazy-skill

Adding Lazy Skills

1. Place skill file at ~/.claude/lazy-skills/<name>.md or clone a skill repo to ~/.claude/lazy-skills/<name>/
2. Edit the index in the installed skill (~/.claude/skills/lazy-skill/SKILL.md):

## Index
- **skillname**: keyword1, keyword2 - "Brief description"
- **reponame** [collection]: keywords - "Description"  # for skill repos

Supported Structures

~/.claude/lazy-skills/
├── stripe.md                    # single file
├── dokploy/                     # single skill repo
│   └── SKILL.md
└── threejs-skills/              # skill collection (multiple skills)
    ├── README.md                # shows available skills
    └── skills/
        ├── threejs-fundamentals/
        │   └── SKILL.md
        └── ...

• Single skills: auto-detects <name>.md or <name>/SKILL.md
• Collections: mark with [collection] in index, reads README first
