Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00449 | $0.00449 |
| Opus 5 | $0.00225 | $0.00225 |
| Sonnet 5 | $0.00090 | $0.00090 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
matterbridge-zigbee2mqtt copilot-instructions.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 5d 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.
This is a copy
100% identical to matterbridge-hass copilot-instructions.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Matterbridge Workspace Instructions (v.1.0.2)
Style And Formatting
- Follow STYLEGUIDE.md for code style, naming, JSDoc, validation, logging, and formatting expectations.
- JSDoc requirements are enforced by the configured linter. Treat missing or incomplete JSDoc on required APIs as a real lint issue, not optional documentation.
- Import and export ordering are enforced by the formatter. Preserve the existing grouped and sorted order unless a change requires updating it.
- Formatting is enforced by oxfmt. Follow the existing formatting and do not fight the formatter.
Scope And Safety
- Keep changes minimal and scoped to the request. Avoid unrelated refactors or broad cleanup.
- Do not modify production code only to make a test pass. If a failing test points to a likely source issue, explain the issue and change behavior only when required by the task.
- Preserve cross-platform behavior. Changes must work on Windows, macOS, and Linux, especially for paths, shell commands, environment variables, and networking behavior.
- Maintain compatibility with the supported Node.js versions in this repository: 20.19, 22.13, 24, and 26.
Project Architecture
- This repository uses TypeScript and ESM. Follow existing project patterns for imports, exports, build configuration, and test setup.
Testing And Validation
- Prefer the existing npm scripts in package.json and the VS Code tasks in tasks.json for building, linting, and testing.
- Keep tests deterministic and simple. Prefer small data sets and straightforward setup.
- Some tests are intentionally multi-step flows. State may persist across successive steps within a single test flow, but each test unit must remain isolated from other tests.
- For validation, run the relevant full test file or the matching suite/task for the touched area rather than assuming arbitrary isolated single-test execution is reliable.
Documentation
- When behavior changes, update the relevant tests and documentation.
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.
