specialization

specialization is a command for Claude Code from nmime/motiv-buy. It costs 0 tokens per session (341 once invoked), scanned A, a copy of specialization, MIT.

A system for training agents to focus on particular programming languages, file types, or tasks. It records areas of expertise and shares learning from edits, reviews, fixes, and optimizations across sessions.

In plain words
What is it for?
Use it to create agents focused on JavaScript, TypeScript, Python, Go, Rust, React, testing, or other declared capabilities, then inspect their specialization levels.
Why use it?
A general-purpose agent may not follow the conventions of a specific language or task. Specialization gives later work a defined focus based on the selected capabilities and accumulated examples.

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

specialization 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 yesterday.

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.

Origin

This is a copy

95% identical to specialization — 28 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Agent Specialization Training

Purpose

Train agents to become experts in specific domains for better performance.

Specialization Areas

1. By File Type

Agents automatically specialize based on file extensions:

  • .js/.ts: Modern JavaScript patterns
  • .py: Pythonic idioms
  • .go: Go best practices
  • .rs: Rust safety patterns

2. By Task Type

Tool: mcp__claude-flow__agent_spawn
Parameters: {
  "type": "coder",
  "capabilities": ["react", "typescript", "testing"],
  "name": "React Specialist"
}

3. Training Process

The system trains through:

  • Successful edit operations
  • Code review patterns
  • Error fix approaches
  • Performance optimizations

4. Specialization Benefits

# Check agent specializations
Tool: mcp__claude-flow__agent_list
Parameters: {"swarmId": "current"}

Result shows expertise levels:
{
  "agents": [
    {
      "id": "coder-123",
      "specializations": {
        "javascript": 0.95,
        "react": 0.88,
        "testing": 0.82
      }
    }
  ]
}

Continuous Improvement

Agents share learnings across sessions for cumulative expertise!

CLI Usage

# Train agent specialization via CLI
npx claude-flow train agent --type coder --capabilities "react,typescript"

# Check specializations
npx claude-flow agent list --specializations

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.

specialization is a command published in the GitHub repository nmime/motiv-buy (0 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 341 tokens. A static security scan graded it A with 0 findings. It is 95% identical to specialization, differing in 28 lines, and is treated as a copy.
