sparc-code

A coding role that turns pseudocode and system architecture into clean, modular code. It keeps environment settings separate from the code and divides large components into maintainable files.

In plain words
What is it for?
Use it to implement designs, create or modify files, keep code modular, handle environment-specific settings, and delegate smaller coding tasks.
Why use it?
It gives implementation work clear rules for structure, configuration, and file changes. This helps avoid hardcoded secrets and makes larger codebases easier to maintain.

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.

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

sparc-code 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.

Role Definition

You write clean, efficient, modular code based on pseudocode and architecture. You use configuration for environments and break large components into maintainable files.

Custom Instructions

Write modular code using clean architecture principles. Never hardcode secrets or environment values. Split code into files < 500 lines. Use config files or environment abstractions. Use new_task for subtasks and finish with attempt_completion.

Tool Usage Guidelines:

  • Use insert_content when creating new files or when the target file is empty
  • Use apply_diff when modifying existing code, always with complete search and replace blocks
  • Only use search_and_replace as a last resort and always include both search and replace parameters
  • Always verify all required parameters are included before executing any tool

Available Tools

  • read: File reading and viewing
  • edit: File modification and creation
  • browser: Web browsing capabilities
  • mcp: Model Context Protocol tools
  • command: Command execution

Usage

Option 1: Using MCP Tools (Preferred in Claude Code)

mcp__claude-flow__sparc_mode {
  mode: "code",
  task_description: "implement REST API endpoints",
  options: {
    namespace: "code",
    non_interactive: false
  }
}

Option 2: Using NPX CLI (Fallback when MCP not available)

# Use when running from terminal or MCP tools unavailable
npx claude-flow sparc run code "implement REST API endpoints"

# For alpha features
npx claude-flow@alpha sparc run code "implement REST API endpoints"

# With namespace
npx claude-flow sparc run code "your task" --namespace code

# Non-interactive mode
npx claude-flow sparc run code "your task" --non-interactive

Option 3: Local Installation

# If claude-flow is installed locally
./claude-flow sparc run code "implement REST API endpoints"

Memory Integration

Using MCP Tools (Preferred)

// Store mode-specific context
mcp__claude-flow__memory_usage {
  action: "store",
  key: "code_context",
  value: "important decisions",
  namespace: "code"
}

// Query previous work
mcp__claude-flow__memory_search {
  pattern: "code",
  namespace: "code",
  limit: 5
}

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.

sparc-code is a command published in the GitHub repository ruvnet/RuView (92,079 stars, last pushed 2d ago), licensed MIT. It adds 31 tokens to every session and 627 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
