What is codex-status-bar AGENTS.md?

Repository-specific instructions for Codex Status Bar, a read-only macOS menu-bar app that displays local Codex activity.

Use them when changing activity parsing, status labels, client badges, Swift code, shell scripts, tests, or release behavior.

They define the app's architecture, privacy limits, testing expectations, and safe handling of Codex's local files.

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	$0.00862	$0.00862
Opus 5.5	$0.00345	$0.00345
Sonnet 5.5	$0.00172	$0.00172

Security

Grade A, and why

codex-status-bar 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.

Repository Instructions

Read README.md before making changes. Follow the product behavior, privacy boundaries, build commands, distribution notes, and local-state assumptions documented there.

Engineering Expectations

Prefer the existing SwiftPM layout: keep platform-independent parsing, state, formatting, and presentation logic in Sources/CodexBarCore, and keep AppKit/menu-bar wiring in Sources/CodexBar.
Use Swift and macOS best practices for a small native menu-bar app: value types for pure model/presentation state, dependency injection for filesystem/environment readers, main-thread AppKit updates, and no unnecessary global state.
Keep Codex Status Bar local-first and read-only for Codex activity data. Do not add network calls, telemetry, hooks, or writes to session JSONL/global state.
Treat Codex local files as implementation details, not a stable public API. Add or update focused tests when parsing new JSONL events, state files, metadata fields, or status labels.
Use originator only for visible APP/CLI/IDE client badges. Do not fall back to noisy source metadata for badge display.
For shell scripts, fail fast on errors, quote paths, avoid destructive commands, and keep release packaging reproducible from ./build.sh --dmg.
For release packaging, assemble, sign, and verify the app in a clean staging directory, then publish final artifacts into build/. In-place local app copies are fine for development, but the DMG should come from the verified staged app.

Verification

Run the narrowest relevant checks for the change:

swift test
./build.sh --release

For packaging changes, also run:

./build.sh --dmg
hdiutil verify build/CodexStatusBar.dmg

For launch or AppKit behavior changes, run:

./script/build_and_run.sh --verify

Generated build artifacts under .build/, build/, dist/, .swiftpm/, and DerivedData/ should stay untracked.

Release Procedure

Only the maintainer publishes releases. App bundle versions are controlled by VERSION and BUILD_NUMBER:

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.
