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 | $0.03822 | $0.03822 |
| Opus 5 | $0.01911 | $0.01911 |
| Sonnet 5 | $0.00764 | $0.00764 |
| Haiku 4.5 | $0.00382 | $0.00382 |
Grade A, and why
chamber 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Copilot Instructions — Chamber
These instructions tell Copilot how to produce code that fits the Chamber codebase. They reflect patterns that already exist here. When in doubt, prefer consistency with surrounding code over external best practices.
Priority Guidelines
- Version compatibility — match the exact versions pinned in
package.jsonand.nvmrc. Never use APIs newer than what is installed. - Architecture first — respect the dependency direction described in Architecture below. A change that violates it is wrong, even if it compiles.
- Read these files first when context is needed:
AGENTS.md,CONTRIBUTING.md,CHANGELOG.md,tsconfig.json,eslint.config.mjs. - Codebase patterns over invention — scan neighboring files (same folder, same kind of test, same kind of service) and copy their shape. Do not introduce a pattern that does not already exist somewhere in
src/. - Security boundaries are non-negotiable — see Security below.

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.

chamber copilot-instructions.md is an instructions file published in the GitHub repository ianphil/chamber (11 stars, last pushed 1mo ago), licensed MIT. It adds 3,822 tokens to every session, about $0.0191 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
