select-tool

select-tool is a command for coding agents from SuperClaude-Org/SuperClaude_Plugin. It costs 15 tokens per session (776 once invoked), scanned A, a copy of select-tool, MIT.

A command that chooses between available MCP tools by examining what an operation needs, such as its size, language, framework, and required accuracy.

In plain words
What is it for?
Use it to route coding operations to the better-matched MCP tool and to inspect or explain that choice.
Why use it?
It removes the need to decide manually which tool fits a task. It also makes the speed-versus-accuracy trade-off explicit.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add commands/superclaude-org/superclaude_plugin/sc-select-tool
Clone the repo
git clone --depth 1 https://github.com/SuperClaude-Org/SuperClaude_Plugin

Or install sc, the plugin that ships this one along with the rest of its 32 commands, 20 agents.

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

select-tool 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 4d 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.

/sc:sc:sc:select-tool - Intelligent MCP Tool Selection

Triggers

  • Operations requiring optimal MCP tool selection between Serena and Morphllm
  • Meta-system decisions needing complexity analysis and capability matching
  • Tool routing decisions requiring performance vs accuracy trade-offs
  • Operations benefiting from intelligent tool capability assessment

Usage

/sc:sc:select-tool [operation] [--analyze] [--explain]

Behavioral Flow

  1. Parse: Analyze operation type, scope, file count, and complexity indicators
  2. Score: Apply multi-dimensional complexity scoring across various operation factors
  3. Match: Compare operation requirements against Serena and Morphllm capabilities
  4. Select: Choose optimal tool based on scoring matrix and performance requirements
  5. Validate: Verify selection accuracy and provide confidence metrics

Key behaviors:

  • Complexity scoring based on file count, operation type, language, and framework requirements
  • Performance assessment evaluating speed vs accuracy trade-offs for optimal selection
  • Decision logic matrix with direct mappings and threshold-based routing rules
  • Tool capability matching for Serena (semantic operations) vs Morphllm (pattern operations)

MCP Integration

  • Serena MCP: Optimal for semantic operations, LSP functionality, symbol navigation, and project context
  • Morphllm MCP: Optimal for pattern-based edits, bulk transformations, and speed-critical operations
  • Decision Matrix: Intelligent routing based on complexity scoring and operation characteristics

Tool Coordination

  • get_current_config: System configuration analysis for tool capability assessment
  • execute_sketched_edit: Operation testing and validation for selection accuracy
  • Read/Grep: Operation context analysis and complexity factor identification
  • Integration: Automatic selection logic used by refactor, edit, implement, and improve commands

Key Patterns

  • Direct Mapping: Symbol operations → Serena, Pattern edits → Morphllm, Memory operations → Serena
  • Complexity Thresholds: Score >0.6 → Serena, Score <0.4 → Morphllm, 0.4-0.6 → Feature-based
  • Performance Trade-offs: Speed requirements → Morphllm, Accuracy requirements → Serena
  • Fallback Strategy: Serena → Morphllm → Native tools degradation chain

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.

select-tool is a command published in the GitHub repository SuperClaude-Org/SuperClaude_Plugin (55 stars, last pushed 14d ago), licensed MIT. It adds 15 tokens to every session and 776 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to select-tool, differing in 10 lines, and is treated as a copy.
