arch

arch is an agent for coding agents from hannsxpeter/scriveno. It costs 0 tokens per session (424 once invoked), scanned A, original, MIT.

A placeholder for storing project-specific architecture guidance, meaning how the main parts of a system are organized and connected.

In plain words
What is it for?
Recording architecture context, decisions, workflows, warnings, and links to related planning artifacts.
Why use it?
It is meant to stop the agent from guessing important structural decisions. The current content is only a stub and imported planning history, so it asks before making lasting choices.

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

arch 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.

  • [DECISION] Treat this artifact as a Godpowers seed until a specialist command validates or rewrites it.
  • [DECISION] Imported source files remain historical evidence, not Godpowers source of truth.
  • [HYPOTHESIS] legacy planning source .planning/archive/01-12-historical-REVIEW-FIX.md may inform this 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.
