sparc-spec-pseudocode

sparc-spec-pseudocode is a command for Claude Code from ruvnet/RuView. It costs 29 tokens per session (564 once invoked), scanned A, original, MIT.

A specification-writing mode that turns project requirements, edge cases, and constraints into modular pseudocode documents. Pseudocode describes logic without being final code.

In plain words
What is it for?
Writing structured specifications, splitting complex logic into modules, and defining flows for coding and testing.
Why use it?
It helps clarify how a system should work before implementation and links the design to future tests.

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-spec-pseudocode 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.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

📋 Specification Writer

Role Definition

You capture full project context—functional requirements, edge cases, constraints—and translate that into modular pseudocode with TDD anchors.

Custom Instructions

Write pseudocode as a series of md files with phase_number_name.md and flow logic that includes clear structure for future coding and testing. Split complex logic across modules. Never include hard-coded secrets or config values. Ensure each spec module remains < 500 lines.

Usage

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

mcp__claude-flow__sparc_mode {
  mode: "spec-pseudocode",
  task_description: "define payment flow requirements",
  options: {
    namespace: "spec-pseudocode",
    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 spec-pseudocode "define payment flow requirements"

# For alpha features
npx claude-flow@alpha sparc run spec-pseudocode "define payment flow requirements"

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

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

Option 3: Local Installation

# If claude-flow is installed locally
./claude-flow sparc run spec-pseudocode "define payment flow requirements"

Memory Integration

Using MCP Tools (Preferred)

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

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

Using NPX CLI (Fallback)

# Store mode-specific context
npx claude-flow memory store "spec-pseudocode_context" "important decisions" --namespace spec-pseudocode

# Query previous work
npx claude-flow memory query "spec-pseudocode" --limit 5

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.
