tdmcp-tool-builder SKILL.md skillB
This file is byte-identical to the first copy the registry indexed, one of 4 indexed copies. Same content hash, so the same checks give both the same grade.
tdmcp-tool-builder from hybridlabor-api/aos is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

How to author one new tdmcp MCP tool the house way — the file shape (XImpl + registerX), the Python-bridge pattern (buildPayloadScript/parsePythonReport over executePythonScript), the result helpers (errorResult/guardTd/jsonResult/structuredResult), fail-forward error handling, ESM/.js + Biome style, and the offline msw unit test that proves it. Load this whenever building, extending, reviewing, or testing a tdmcp tool file under src/tools/** (and its test under tests/unit/**). Use it for…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# tdmcp-tool-builder
You build **one** new tdmcp tool, end to end, matching the repo so closely a
reviewer cannot tell which files are new. tdmcp is a TouchDesigner MCP server: a
Node/TS server (this repo) drives a Python **bridge** running *inside*
TouchDesigner. A "tool" is a TS handler that the AI can call; most tools do their
work by sending one Python script to the bridge and parsing a JSON report back.
The canonical template is **`src/tools/layer2/manageComponent.ts`**. Read it
first, every time. Copy its shape exactly. The rules below explain *why* each
piece exists so you make the right call on edge cases.
## The contract: one file, two exports (+ schema)
Every tool file exports three things and nothing surprising:
1. `export const xSchema = z.object({ … })` — the Zod input schema. Each field
gets a `.describe()` written for an AI caller (say what it does and the units).
2. `export async function xImpl(ctx: ToolContext, args): Promise<CallToolResult>`
— the **pure, testable** handler. It takes the injected `ToolContext`
(`{ client, knowledge, recipes, logger, vault?, allowRawPython }`) and the
…Read the whole file at its exact version.
How to install
mdr add hybridlabor-api/aos/tdmcp-tool-builder@sha256:1f34a1c9e3950797The line at the top of this page pins the label git:20260813.2e0e3da, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
