  • Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.

    Of the AGENTS.md files we read, the 31,774 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.

We split this AGENTS.md into the rules it gives an agent

1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.

≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Purpose

FastMCP 3.4 server wrapping MiDashengLM-Gen (Xiaomi Research): unified 16 kHz mixed audio scene generation (speech, music, SFX, ambience) from structured text captions. LLM-driven autoregressive flow matching with a Qwen3-1.7B backbone (2.9B params total). Apache-2.0, runs locally on CUDA.

Layout

src/midasheng_gen_mcp/
  server.py          FastMCP instance (shared), lifespan, FastAPI build
  main.py            Dual transport entry (stdio default, HTTP on MCP_PORT)
  config.py          Settings from MIDASHENG_* env vars
  model_manager.py   Lazy torch/transformers load, generate, state machine
  jobs.py            Async job runner + prompt builder
  db.py              SQLite scenes + jobs store (WAL)
  samples.py         Built-in example captions
  audio.py           WAV metadata + persistence helpers
  logs.py            Ring-buffer log store
  mcp/tools/         audio_scene portmanteau, help, prefab cards
  api/routes/        REST: health, dashboard, scenes, jobs, audio, tools,
                     skills, samples, logs, llm, model, capabilities
  skills/midasheng-gen/SKILL.md
webapp/              React + Vite + Tailwind SOTA dashboard (port 11160)
tests/               15 pytest tests (no torch required)

Key facts

  • Ports: backend 11159 (REST + MCP /mcp), frontend 11160 (registered in WEBAPP_PORTS.md)
  • The shared FastMCP instance lives in server.py; tool modules import mcp from there (registration at import time - no import = no tool)
  • uv sync --extra model installs torch/transformers; without it the server runs but reports not_installed state (declared, not fake)
  • Model checkpoint: mispeech/midashenglm-gen on Hugging Face (~6 GB), auto-download via start.ps1 or the download_model operation
  • Structured caption: <|caption|> <|asr|> <|speech|> <|sfx|> <|music|> <|env|> views; absent views become <|unknown|>
  • MCP generate is synchronous; the webapp uses the async job API (POST /api/generate -> job id -> GET /api/jobs/{id})

Commands

just lint         ruff check + format --check
just test         pytest (light, no torch)
just web-check    tsc --noEmit + biome check (webapp)
just ci           lint + test
just mcpb-pack    fresh-stage MCPB bundle
just model-download   installs model extra + downloads checkpoint

Conventions

  • Fleet standards: mcp-central-docs (AGENTS.md gate, SOTA, WEBAPP_PORTS)
  • No em dashes in any file; ASCII only
  • Dialogic returns: {success, message, ...}; _error_response auto-logs
  • Prefab cards for list/status surfaces (show_scene_status_card etc.)

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
