What is sophotron AGENTS.md?

Repository instructions for coding agents working on the Sophotron project. They explain which project guides to read, how to verify changes, and rules for reporting results.

Use them when modifying Sophotron, especially to follow its architecture, contribution process, writing rules, testing commands, and error-handling requirements.

They give an agent the project’s requirements before it edits code, helping avoid incorrect changes and misleading reports.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00170	$0.00170
Opus 5.5	$0.00068	$0.00068
Sonnet 5.5	$0.00034	$0.00034

Security

Grade A, and why

sophotron AGENTS.md 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 2mo 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

Agent instructions

The operational guide for this repo lives in CLAUDE.md — architecture, module conventions, correctness contracts, and the verification commands that define "done". It is harness-agnostic despite the name; read it in full before editing anything.

Also binding:

CONTRIBUTING.md — workflow, review process, and the claims discipline for PR descriptions (state only what was actually run).
docs/style-guide.md — for any public-facing prose you write, including PR descriptions.

Two rules worth repeating because violations are silent: stdout is the MCP transport (log to stderr only), and a transient upstream failure (429/5xx) must never be reported as a genuine empty result.

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.
