What is cutible AGENTS.md?

Project instructions for Cutible, a headless video-editing engine that works without a visual editor. They describe its layered structure, development commands, and interfaces, including an MCP server.

Use them when modifying the engine, its media-processing layers, its command-line tools, or its programming interfaces.

They help an agent understand where video-editing behavior belongs and how to build and test changes safely.

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	$0.00889	$0.00889
Opus 5.5	$0.00356	$0.00356
Sonnet 5.5	$0.00178	$0.00178

Security

Grade A, and why

cutible 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 Guidelines

Project Structure & Module Organization

Cutible is a headless video-editing engine with 5 architectural layers:

Layer	Modules	Role
L1 Core	`schema.py`, `verbs.py`	Timeline-as-Data (Pydantic) + 14 low-level verb primitives
L2 Render	`compiler.py`, `qc.py`	Deterministic FFmpeg render + probe-based QC
L3 Capabilities	`verbs_high.py`, `ingest/`, `index/`, `perception/`, `render_farm/`, `remotion/`, `otio_bridge/`	Composite verbs, media ingest, semantic search, VLM review, distributed render, OTIO interop
L4 Agents	`agents/`	Multi-agent swarm: Planner → Editor → Sound → QC → Orchestrator
L5 Interfaces	`cli.py`, `mcp_server.py`, `api/app.py`, `sdk/client.py`, `sdk_ts/`	CLI, MCP (35 tools), REST API, Python SDK, TypeScript SDK

The primary agent interface is the MCP server (mcp_server.py): 35 JSON-RPC 2.0 tools over stdio. The REST API and SDKs are secondary.

Key pattern: every verb returns a Diff, errors return VerbError(hint, context). The Project (Pydantic model) is the single source of truth — JSON, diffable, auditable.

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.
