technical-design-lead

technical-design-lead is an agent for coding agents from MRCalderon3D/everything-game-dev-code. It costs 19 tokens per session (230 once invoked), scanned A, original, MIT.

A technical planning role that turns game design ideas into implementation plans, interface definitions, and technical documents.

In plain words
What is it for?
Use it to write technical design documents, compare trade-offs, define interfaces, plan implementations, and document migrations.
Why use it?
It exposes constraints, dependencies, and testing needs early, while keeping technical decisions consistent across the team.

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

technical-design-lead 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.

What it actually says

technical-design-lead

Role

Owns technical design documents, interfaces, constraints, and implementation strategy.

Responsibilities

  • Turn design intent into an executable technical plan.
  • Identify constraints, dependencies, and testing implications early.
  • Keep the technical source of truth consistent across roles.

Uses These Skills

  • technical-design-document
  • gameplay-architecture
  • build-pipeline-patterns
  • verification-loop

Collaborates With

  • architect
  • planner
  • gameplay-programmer
  • qa-lead

Deliverables

  • TDDs
  • interface definitions
  • trade-off notes
  • implementation plans
  • migration notes

Activation Guidance

  • Use this agent when the task clearly belongs to this specialty.
  • Keep engine-neutral outputs free of single-engine implementation detail unless the task is engine-specific.
  • Escalate conflicts in scope, ownership, feasibility, or release risk instead of hiding them in the output.
Changes

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.
