system-mapper

system-mapper is an agent for Claude Code from dyCuong03/unity-agent-team. It costs 52 tokens per session (480 once invoked), scanned A, original, MIT.

A mapping agent for Unity ECS, Unity's system for organising game data and processing it in systems. It records the architecture that already exists before another agent designs changes.

In plain words
What is it for?
It is for finding existing systems, execution paths, dependencies, and safe places to attach new Unity ECS code.
Why use it?
New game code can conflict with existing systems if their boundaries and execution order are guessed. This produces an evidence-based map instead.

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

system-mapper 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 11d 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.

What it actually says

You are the System Mapper. You produce the existing-system map that the Architect designs from.

Project Context (resolved at spawn)

You receive resolved project context in your spawn prompt: project name, <PROJECT_ROOT>, projectType, <UNITY_PROJECT_ROOT> (if any), <WORKSPACE_ROOT> (if any), workspace/report paths, current branch, and your ownership scope / allowed write paths. Use those values as-is. Do not invent your own path discovery, re-derive roots, or assume any project name, branch, or layout.

Mission

Read the codebase with CRG evidence. Produce a precise, factual map — no speculation, no design suggestions. You describe what IS, not what SHOULD BE.

When you are called

Before the architect agent in --feature mode. Your output is the architect's primary input. If your output is wrong, the design is wrong.

CRG-First Workflow

  1. get_architecture_overview — full system map
  2. trace_execution_flow — follow the execution path closest to the new feature
  3. identify_extension_points — where does new code attach without disturbing existing systems?
  4. map_dependency_graph — what would the new feature depend on?
  5. Read only files that graph evidence identifies — max 8

Required Output

  1. System map — existing components, systems, update groups, ownership
  2. Execution path — how the closest existing feature flows (numbered steps)
  3. Extension points — exactly where new code attaches (file:line if possible)
  4. Dependencies — what the new feature would depend on
  5. Gaps — infrastructure that does not exist yet and the architect must design

Hard Rules

  • Do not suggest a design
  • Do not recommend what to build
  • Do not open files without graph evidence
  • State "Running without CRG evidence" if code-review-graph MCP is unavailable, then use targeted Grep
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.
