What it does

Ipc Contract Design is an agent skill from muratgur/ordinus. Design and maintain Ordinus typed IPC contracts. Use when adding or changing window.ordinus APIs, ipcMain handlers, ipc channel names, shared request/response types, Zod schemas, preload bridge methods, or renderer calls into main process.

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Frontend & Design, covering Forms and validation. It works with Zod. The repository describes itself as: Your local-first command center for working with AI agents like a real team. The licence is MIT.

When your agent uses it

  • Changing window.ordinus APIs
  • IpcMain handlers
  • Ipc channel names
  • Shared request/response types

Example prompts

  • “/ipc-contract-design”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Name the user-facing capability before creating an IPC method.
  2. Add or update shared types and Zod schemas.
  3. Add the IPC channel constant.
  4. Implement the main handler and validate untrusted input.
  5. Add the narrow preload method that invokes that channel.
  6. Consume the method in renderer through window.ordinus.
  7. Run typecheck, lint, and build.

What it can do on your machine

Read from SKILL.md and the folder at commit c27f289. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ipc Contract Design loads about 509 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 230 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~509

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Design and maintain Ordinus typed IPC contracts. Use when adding or changing window.ordinus APIs, ipcMain handlers, ipc channel names, shared request/response types, Zod schemas, preload bridge methods, or renderer calls into main process.

IPC Contract Design

Objective

Keep Ordinus IPC small, typed, explicit, and stable enough for the renderer to act as a safe UI over main-process capabilities.

Contract Shape

  • Define channel names in src/shared/ipc.ts.
  • Define shared request/response schemas and types in src/shared/contracts.ts.
  • Register handlers in main process modules, not renderer.
  • Expose renderer-facing methods through window.ordinus in preload.
  • Use feature-shaped methods such as workspace.selectFolder() instead of generic transport methods.

Workflow

  1. Name the user-facing capability before creating an IPC method.
  2. Add or update shared types and Zod schemas.
  3. Add the IPC channel constant.
  4. Implement the main handler and validate untrusted input.
  5. Add the narrow preload method that invokes that channel.
  6. Consume the method in renderer through window.ordinus.
  7. Run typecheck, lint, and build.

Guidelines

  • Keep method names domain-oriented: app.getInfo, db.getStatus, workspace.selectFolder.
  • Prefer one explicit method over a generic catch-all channel.
  • Keep renderer errors user-readable and main errors diagnostic enough to debug.
  • When IPC responses drive renderer status, empty states, or error copy, align user-visible naming with DESIGN.md.
  • Do not add IPC for future features until there is an immediate caller.
  • Do not return secrets, raw environment details, or unrestricted local paths unless the UI truly needs them.

Anti-Patterns

  • window.ordinus.invoke(channel, payload).
  • Passing raw command strings from renderer to main.
  • Duplicating response shapes separately in main and renderer.
  • Letting renderer decide privileged policy such as workspace boundaries or executable paths.
