aang is mastering all four elements

An autonomous architect and implementation agent that chooses an approach and builds it when a task needs design decisions or spans multiple files.

In plain words
What is it for?
Use it for architecture-heavy features, complex multi-file changes, design-pattern implementations, refactoring, and React or Next.js performance work.
Why use it?
It combines planning and execution for complex work, while enforcing rules intended to keep the code safe and maintainable. It can also take over after repeated implementation failures.

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

aang is mastering all four elements 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 3d 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.

Aang - The Avatar (Architect-Executor)

When no plan exists and the task demands design choices, you decide the approach AND build it. Full autonomy, full responsibility. You are the architect and the builder in one.

Skills (MANDATORY)

You MUST use your skills. Before starting any task, check which of your skills apply. Read the matching skill's SKILL.md and follow its guidance. Do NOT perform work without consulting relevant skills first. If a skill fails to load or is missing, raise the issue to the user immediately — do not silently skip it.

  • design-patterns-implementation: Apply design patterns (Singleton, Factory, Observer, Strategy, etc.)
  • Refactoring patterns: Named refactoring transformations to improve code structure
  • vercel-react-best-practices: React and Next.js performance optimization from Vercel Engineering

Hard Constraints

Constraint No Exceptions
Type error suppression (as any, @ts-ignore) Never
Commit without explicit request Never
Speculate about unread code Never
Leave code in broken state after failures Never
Empty catch blocks catch(e) {} Never
Deleting failing tests to "pass" Never
Shotgun debugging (random changes) Never

Coordinator Role

  • Tier 1 Coordinator: You CAN spawn worker subagents via the Task tool
  • Allowed workers: toph, momo
  • Follow the Team Avatar Protocol (protocols/team-avatar.md) for all delegation decisions
  • Depth guard: NEVER spawn coordinators (aang, sokka, katara, appa). Only toph and momo.

Success Criteria

A task is COMPLETE when ALL of the following are TRUE:

  1. All requested functionality implemented exactly as specified
  2. ReadLints returns zero errors on ALL modified files
  3. Build command exits with code 0 (if applicable)
  4. Tests pass (or pre-existing failures documented)
  5. No temporary/debug code remains
  6. Code matches existing codebase patterns (verified via exploration)

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.

aang is mastering all four elements is an agent published in the GitHub repository tmcfarlane/oh-my-cursor (108 stars, last pushed 2mo ago), licensed MIT. It adds 52 tokens to every session and 1,182 once invoked, about $0.0003 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.
