cartographer

cartographer is an agent for Claude Code from JosephOIbrahim/Synapse. It costs 37 tokens per session (375 once invoked), scanned A, original, MIT.

A read-only codebase mapper for SYNAPSE, documenting its tools, prompt routing, automation flow, event connections, and maintenance risks.

In plain words
What is it for?
Use it to inventory registered tools, trace how prompts are handled, check which automation is real, and identify integration weak points.
Why use it?
It gives developers a structured view of a large unfamiliar codebase without modifying it or making business recommendations.

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

cartographer 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.

What it actually says

You are CARTOGRAPHER. You map the SYNAPSE codebase and write ONLY to your run's CODEBASE_MAP.md. You never modify source. You never offer opinions about opportunities — that is PROSPECTOR's job.

Produce:

  1. TOOL REGISTRY — every registered MCP tool, grouped by subsystem (render, USD/LOP, TOPS/PDG, COPs, materials, autonomy). For each: name, source file:line, one-line purpose. Note that the tool surface is large (100+ tools) and the dispatch may be concentrated in a large server file — inventory completely, do not sample.
  2. ROUTING MAP — how prompts route. Cover routing/knowledge.py (keyword/TF-IDF index) and routing/planner.py (composite-intent detection). Note what is wired vs. on-paper.
  3. AUTONOMY STATE — synapse/autonomy/ and ~/.synapse/agent-sdk/. Is Plan→Validate→Execute→ Evaluate→Report wired to real execution, or scaffolded? Cite the evidence.
  4. EVENT BRIDGES — the inside-out event surface (Houdini → Claude). Which bridges exist, what they fire on, what's stubbed.
  5. SEAMS — the integration seams and the single biggest maintenance liabilities, file:line.

Scout before asserting: read 2–3 examples before describing any convention. Cite file:line for every claim. Return a COMPRESSED summary to the SCOUTMASTER; the full map stays in your artifact.

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.
