FluidAudio AGENTS.md

Repository instructions for FluidAudio, a Swift library and command-line tool that turns audio into timestamped transcripts and separates different speakers. They cover its structure, build and test commands, and coding rules.

In plain words
What is it for?
Use them when developing FluidAudio, running Swift tests, formatting its source, or changing its audio-processing pipeline.
Why use it?
They tell the coding agent how to build, format, and test the project while avoiding unsafe shortcuts such as fake models or incorrect thread handling.

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

FluidAudio 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 2d 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.

Origin

This is a copy

100% identical to FluidAudio copilot-instructions.md — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Build & Test Commands

swift build                                    # Build project
swift build -c release                        # Release build
swift test                                     # Run all tests
swift test --filter CITests                   # Run single test class
swift test --filter CITests.testPackageImports # Run single test method
swift format --in-place --recursive --configuration .swift-format Sources/ Tests/

Architecture

  • FluidAudio/: Main library (ASR/, Diarizer/, VAD/, Shared/ modules)
  • FluidAudioCLI/: CLI tool with benchmarking and processing commands
  • Tests/FluidAudioTests/: Comprehensive test suite
  • Models: Auto-downloaded from HuggingFace with CoreML compilation
  • Processing Pipeline: Audio → VAD → Diarization → ASR → Timestamped transcripts

Critical Rules

  • NEVER use @unchecked Sendable - implement proper thread safety with actors/MainActor
  • NEVER create dummy/mock models or synthetic audio data - use real models only
  • NEVER create simplified versions - implement full solutions or consult first
  • NEVER run git push unless explicitly requested by user
  • Add unit tests when writing new code

Code Style (swift-format config)

  • Line length: 120 chars, 4-space indentation
  • Import order: Alphabetical preferred (import CoreML, import Foundation, import OSLog), but OrderedImports rule is disabled due to Swift 6.1 (GitHub Actions CI) vs 6.3 (local) formatter incompatibility
  • Naming: lowerCamelCase for variables/functions, UpperCamelCase for types
  • Error handling: Use proper Swift error handling, no force unwrapping in production
  • Documentation: Triple-slash comments (///) for public APIs
  • Thread safety: Use actors, @MainActor, or proper locking - never @unchecked Sendable
  • Control flow: Prefer flattened if statements with early returns/continues over nested if statements. Use guard statements and inverted conditions to exit early. Nested if statements should be absolutely avoided.

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.
