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.
npx agentmods add instructions/boecht/birre/copilot-instructionsgit clone --depth 1 https://github.com/boecht/birreWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01799 | $0.01799 |
| Opus 5 | $0.00899 | $0.00899 |
| Sonnet 5 | $0.00360 | $0.00360 |
| Haiku 4.5 | $0.00180 | $0.00180 |
Grade A, and why
birre 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 3d 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

2. Core Principles
Project Principles
-
Ground every statement in current evidence.
- Inspect the live repo/docs/logs before forming an opinion or recommending a change
- Cite the exact file/line that supports your conclusion so nothing relies on memory or stale data
-
Clarify, don’t guess
- Whenever something is unclear, inconsistent, or blocking the design goal, pause and ask the user a precise technical question instead of assuming or defaulting
- Only follow a different approach if the prompt/mode explicitly demands it
- Apply this discipline across all stages; requirements, system design, and implementation alike
- Turn every ambiguity or spec gap into a targeted clarification
- Treat uncertainty signals like "I think", "probably", or "maybe" as red flags that require clarification
-
Build a Minimal Viable Product (MVP) for personal use first — iterate and refine only if requested.
- Prioritize functionality and stability over broad compatibility
- Avoid premature optimization for universal use cases
-
Quality and architecture trump backwards compatibility.
- Breaking changes are acceptable if they improve the codebase
- Remove outdated patterns immediately; do not preserve legacy code
- Avoid shortcuts; build the right solution once
- Clean, maintainable architecture outranks legacy API stability
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.

birre copilot-instructions.md is an instructions file published in the GitHub repository boecht/birre (2 stars, last pushed 3d ago), licensed Unlicense. It adds 1,799 tokens to every session, about $0.0090 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 2026-08-31.
