What is mectrics AGENTS.md?

A project instruction file that defines the working rules for mectrics, including English-only contributions, project structure, translations, and menu-bar display.

Use it when modifying the Swift packages, command-line tools, translations, or menu-bar interface.

It gives both people and coding agents one shared source of truth for repository conventions. This reduces inconsistent code, documentation, and user-interface changes.

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	$0.07056	$0.07056
Opus 5.5	$0.02822	$0.02822
Sonnet 5.5	$0.01411	$0.01411
Haiku 4.5	$0.00706	$0.00706

Security

Grade A, and why

mectrics 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 1mo 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.

This file is the source of truth for conventions in this repository. It applies to any AI agent or human contributor. CLAUDE.md points here.

0. Golden rule: English-only repository

Everything committed to this repo is in English — no exceptions:

Source code: identifiers, types, function names, variables.
Comments and documentation comments.
All Markdown docs (README.md, docs/**).
Commit messages, branch names, PR titles/descriptions.
User-facing UI strings: English is the base/development language (localized to other languages via the String Catalog — see §2).

The only place another language may appear is a live chat conversation with the user (who may write in Turkish). Nothing from that chat leaks into the repo in another language.

1. Project shape

Packages/MetricsKit/ — UI-independent metric engine (SwiftPM). Providers, scheduler, ring-buffer store, engine. No UI, no localization (data-only, English identifiers).
- swift build, swift test, swift run metricskit-demo (internal live provider readout).
- swift run mectrics runs the read-only user CLI. It reads alert configuration from the app and offers check, snapshot, event streaming, and rule listing. Tests/MectricsCLITests owns its process, exit-code, JSON-fixture, and failure-path contracts.
- Builds in the Swift 6 language mode and must stay warning-free. MetricProvider requires Sendable; providers are @unchecked Sendable because the engine samples them on one serial queue. Guard anything read outside that queue with a lock.
Mectrics/ — the menu bar app (SwiftUI + AppKit).
project.yml — XcodeGen project definition. This is the source; Mectrics.xcodeproj is generated. After editing project.yml or adding/removing source files, run xcodegen generate.
docs/ — the architecture deep dive, and nothing else. Contributor-facing only: planning notes, roadmaps, backlogs, and maintainer-only runbooks do not belong in the public repository. The release procedure lives in scripts/release.sh, which is self-documenting through its required environment variables.

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.
