Auto-Discovery

Claude Code automatically checks ~/.claude/skills/ for relevant skills before planning tasks:

```

User: "Set up a Cloudflare Worker with D1 database"

↓

Claude: [Checks skills automatically]

↓

Claude: "Found cloudflare-worker-base and cloudflare-d1 skills.

These prevent 12 documented errors. Use them?"

↓

User: "Yes"

↓

Result: Production-ready setup, zero errors, ~65% token savings

```

Note: Due to token limits, not all skills may be visible at once. See [⚠️ Important: Token Limits](#-important-token-limits) below.

Skill Structure

Each skill includes:

```

Skill Visibility Constraint

Claude Code has a 15,000 character limit for the total size of skill descriptions in the system prompt. This limit also applies to commands and agents.

What this means:

• Not all 176 skills may be visible in Claude's context at once
• Skills are loaded based on relevance and available token budget
• You can verify how many skills Claude currently sees by asking: "How many skills do you see in your system prompt?"

Checking Visible Skills

To verify which skills are currently loaded:

```bash

# Ask Claude Code directly

"Check what skills/plugins you see in your system prompt"

```

Claude will report something like: "85 of 176 skills visible due to token limits"

Workaround: Increase Token Budget

You can double the headroom for skill descriptions by setting an environment variable:

```bash

# Increase limit to 30,000 characters

export SLASH_COMMAND_TOOL_CHAR_BUDGET=30000

# Then launch Claude Code

claude

```

This gives you approximately 2x more skill visibility in the system prompt.

Note: This is a temporary workaround. The Claude Code team is working on better solutions for skill discovery and loading.

| Metric | Manual Setup | With Skills | Savings |

|--------|--------------|-------------|---------|

| Average Tokens | 12,000-15,000 | 4,000-5,000 | ~65% |

| Typical Errors | 2-4 per service | 0 (prevented) | 100% |

| Setup Time | 2-4 hours | 15-45 minutes | ~80% |

Across all 176 skills: 400+ documented errors prevented.
