omamail: Instructions file for Codex

AGENTS.md

omamail AGENTS.md is an instructions file for Codex, OpenCode from huacnlee/omamail. It costs 1,728 tokens per session, scanned A, original, MIT.

Repository guidance for Omamail, a desktop application built with QML and JavaScript, covering its visual theme, layout, module organization, libraries, and entry points. It requires colors to come from the active system theme rather than fixed values.

In plain words
What is it for?
Adding or editing views and components, passing theme colors through the application, organizing modules, and following the project's JavaScript and QML conventions.
Why use it?
It helps agents make interface changes that match the application's theme and keep related code together.

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

omamail 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 7d 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.

Structure and boundaries

  • Group by module, not file type. Rust lives in src/, CLI handling in src/cli/, and dispatch in src/backend/. QML and its JavaScript live together under ui/. Rust unit tests live with their modules; UI tests live in ui/tests/; integration tests live in tests/.
  • Rust owns mail business logic and durable agent jobs. QML owns presentation and interaction state, communicating with the persistent backend over stdin/stdout rather than invoking CLI commands. See docs/BACKEND.md and docs/ARCHITECTURE.md.
  • QML JavaScript libraries start with .pragma library and use var and function, not const, let, arrows or template literals. Put testable presentation rules there. Tests load module paths, e.g. load("cache/Cache.js"); ui/tests/load.js resolves QML .import chains.
  • A list or object received through a var signal argument (on Qt 6.12) or a delegate's modelData is a sequence or reference object, not a JavaScript array or object: Array.isArray says no and its keys come back sorted. A receiver that judges such a value, keeps it or writes to it takes Plain.plain (ui/backend/Plain.js) of it first; ui/tests/qml/tst_signal_lists.qml shows the pattern.
  • List new QML files in the Makefile's lint inputs and import other modules explicitly.
  • Service.qml is shell-constructed and must declare no required properties. The shell injects only shell, manifest, pluginRegistry, and barWidgetRegistry; settings arrive through the bar widget's applySettings.

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.
