What is SwiftASB AGENTS.md?

Repository instructions for SwiftASB, a Swift Package Manager library that connects Swift and SwiftUI applications to the local Codex app-server. They describe the package structure, public API boundaries, generated protocol code, and tests.

Use them when modifying SwiftASB's package configuration, public API, transport, history, protocol, generated wire layer, or Swift Testing tests.

They tell contributors where the main code and tests live and which files define the package and wire protocol. This reduces the risk of breaking the public API or changing generated internals incorrectly.

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	$0.03537	$0.03537
Opus 5.5	$0.01415	$0.01415
Sonnet 5.5	$0.00707	$0.00707

Security

Grade A, and why

SwiftASB 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.

AGENTS.md

Repo-local guidance for maintaining SwiftASB, a Swift Package Manager library that wraps the local Codex app-server for Swift and SwiftUI clients.

Repository Scope

What This File Covers

Use this file for all work at the SwiftASB repository root.
Treat this package as a library first: public API should be deliberate, documented, and tested.
Use Swift Package Manager as the source of truth for package structure, dependencies, products, targets, resources, and Swift language mode.
Treat the bundled Codex app-server v2 schema as the primary generated-wire source of truth.
Treat the generated wire layer as internal scaffolding, not the final public Swift API.

Where To Look First

Start with Package.swift for package graph, target, dependency, platform, and Swift language mode changes.
Use Sources/SwiftASB/Public/ for public API shape and Sources/SwiftASB/Protocol/, Sources/SwiftASB/Transport/, and Sources/SwiftASB/History/ for the main internal runtime surfaces.
Use Sources/SwiftASB/Generated/CodexWire/Latest/ for the promoted generated v2 wire snapshot.
Use Tests/SwiftASBTests/ for Swift Testing coverage.
Use scripts/generate-wire-types.sh for Codex schema-derived wire refreshes.
Use scripts/repo-maintenance/ for repo-owned validation, shared sync, and release entrypoints.
Use README.md, CONTRIBUTING.md, ROADMAP.md, and docs/maintainers/ for shipped behavior, contributor workflow, planned work, and durable design decisions.

Working Rules

Change Scope

Prefer the simplest correct Swift that is easiest to read, reason about, and maintain.
Prefer value types for domain modeling.
Prefer concrete types internally and reserve protocols for real seams.
Mark classes final by default when reference semantics are required.
Keep dependency flow unidirectional and ownership obvious.
Prefer explicit, consistent, and unambiguous names.
Prefer synthesized conformances and memberwise initialization whenever they satisfy the real need.
Avoid ceremony, wrappers, or extra abstraction layers unless they solve a concrete package problem.
Keep operator-facing errors, warnings, and log strings descriptive and human-readable.

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.
