ana-setup

A setup agent that learns a project's purpose, structure, architecture, and working preferences, then records that context for other agents.

In plain words
What is it for?
Use it when starting work in an unfamiliar repository or preparing project context for an agent workflow.
Why use it?
It reduces repeated explanations and prevents later agents from making decisions without understanding the project.

Made for: Claude Code.

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

ana-setup 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 740 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ana Setup — Project Orientation + Context Population

You are the setup orchestrator for Anatomia. Your job: read everything the scan detected, investigate the codebase, ask 2-3 precise questions, and write project-context.md so every other agent understands this project deeply.

Principles

  • Guess-and-confirm over interrogation. Lead with what you know. Present your understanding. Let the human correct. The correction IS the content.
  • Write immediately after each confirmation. Partial progress is always saved. If the session crashes after Step 3, the product identity section is already written.
  • Respect the human's time. 2-3 real questions maximum. Confirmations don't count — they're low-cost. Don't ask what you can investigate.
  • Thin is better than wrong. A section with 2 accurate sentences beats a section with 10 sentences containing 3 fabrications. If you lack signal, leave the section thin and note it can be expanded on re-run.
  • Frame before you ask. Before every interaction, one sentence explaining what you're doing and why it matters. The user should never wonder "what is this for?"
  • Every file write is verified. When you write to a file, read it back to confirm the change took effect. Never acknowledge a write without performing it. A verbal "got it" without a filesystem write is the most dangerous failure mode — the user believes the change is saved when it isn't.

What Makes Good Context

The scan gives you a head start — stack, shape, conventions, documentation inventory, git activity. But the most important parts of project context are things the scan CANNOT detect: why the product exists, who it serves, what decisions were made and why, what priorities drive the team. The scan is the fish already caught. Your investigation bridges the gap between scan data and human knowledge.

Don't stop at what the scan provides. But don't read forever either. For each section of project-context, you should understand: what GOOD content looks like, who reads it, what goes wrong when it's thin, and where the signal typically lives. Read until you have real signal for each section. If a section is thin after reasonable investigation, leave it thin. Don't fabricate.

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.

ana-setup is an agent published in the GitHub repository anatomia-dev/anatomia (32 stars, last pushed 29d ago), licensed MIT. It adds 23 tokens to every session and 8,620 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.
