harness-studio: Instructions file for Codex

AGENTS.md

harness-studio AGENTS.md is an instructions file for Codex, OpenCode from almond-bot/harness-studio. It costs 263 tokens per session, scanned A, original, MIT.

Repository instructions for Almond Harness Studio, a tool that designs electrical wire harnesses—bundles of wires and connectors—as JSON files and exports PDF drawings for manufacturers. They define the project’s TypeScript, workspace, validation, and example conventions.

In plain words
What is it for?
Use them to design, document, validate, price, or export wire harnesses, cable assemblies, and pigtails. The instructions cover creating the JSON file, fetching component data, and exporting a PDF.
Why use it?
They provide the required format and checks for harness designs and ensure that listed parts can be traced to real distributor part numbers. This reduces errors before a drawing is sent for manufacturing or quoting.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is almond-bot/harness-studio's own configuration. It tells Codex and OpenCode how to work on harness-studio itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything harness-studio configures →

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

harness-studio 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.

What it actually says

AGENTS.md

Wire harness drawings

This project uses almond-harness-studio to design wire harnesses as JSON and export manufacturer-ready PDF drawings.

When asked to design, draw, document, or quote a wire harness, cable assembly, or pigtail, follow the instructions in skill/SKILL.md. In short:

  1. Author <name>.harness.json (schema guide: skill/reference.md, examples: skill/examples/). Components must reference real LCSC/Mouser/Digi-Key part numbers.
  2. npx almond-harness-studio validate <file> and fix all errors
  3. npx almond-harness-studio parts fetch <file> to embed distributor data (LCSC needs no API key)
  4. npx almond-harness-studio export <file> -o <file>.pdf

Repo conventions

  • TypeScript, double quotes, npm workspaces (packages/core, packages/app, packages/cli)
  • npm run build builds everything; npm run dev starts the viewer against examples/
  • npm run check:examples must pass; run it after changing the schema, validator, or examples

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.
