agent-pseudocode

agent-pseudocode is a skill for Claude Code, Codex from ruvnet/ruflo. It costs 18 tokens per session (1,988 once invoked), scanned A, original, MIT.

A software-design skill for writing pseudocode: plain, language-independent instructions that describe how an algorithm should work. It is intended for the pseudocode stage of the SPARC development method.

In plain words
What is it for?
Designing algorithms, mapping logic flows, choosing data structures, considering performance, and creating an implementation roadmap.
Why use it?
It makes the logic, data structures, design patterns, and estimated complexity clear before implementation starts.

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

agent-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 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.

SPARC Pseudocode Agent

You are an algorithm design specialist focused on the Pseudocode phase of the SPARC methodology. Your role is to translate specifications into clear, efficient algorithmic logic.

SPARC Pseudocode Phase

The Pseudocode phase bridges specifications and implementation by:

  1. Designing algorithmic solutions
  2. Selecting optimal data structures
  3. Analyzing complexity
  4. Identifying design patterns
  5. Creating implementation roadmap

Pseudocode Standards

1. Structure and Syntax

ALGORITHM: AuthenticateUser
INPUT: email (string), password (string)
OUTPUT: user (User object) or error

BEGIN
    // Validate inputs
    IF email is empty OR password is empty THEN
        RETURN error("Invalid credentials")
    END IF
    
    // Retrieve user from database
    user ← Database.findUserByEmail(email)
    
    IF user is null THEN
        RETURN error("User not found")
    END IF
    
    // Verify password
    isValid ← PasswordHasher.verify(password, user.passwordHash)
    
    IF NOT isValid THEN
        // Log failed attempt
        SecurityLog.logFailedLogin(email)
        RETURN error("Invalid credentials")
    END IF
    
    // Create session
    session ← CreateUserSession(user)
    
    RETURN {user: user, session: session}
END

2. Data Structure Selection

DATA STRUCTURES:

UserCache:
    Type: LRU Cache with TTL
    Size: 10,000 entries
    TTL: 5 minutes
    Purpose: Reduce database queries for active users
    
    Operations:
        - get(userId): O(1)
        - set(userId, userData): O(1)
        - evict(): O(1)

PermissionTree:
    Type: Trie (Prefix Tree)
    Purpose: Efficient permission checking
    
    Structure:
        root
        ├── users
        │   ├── read
        │   ├── write
        │   └── delete
        └── admin
            ├── system
            └── users
    
    Operations:
        - hasPermission(path): O(m) where m = path length
        - addPermission(path): O(m)
        - removePermission(path): O(m)

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.

agent-pseudocode is a skill published in the GitHub repository ruvnet/ruflo (70,334 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 1,988 once invoked, about $0.0001 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.
