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 | $0.00224 | $0.00224 |
| Opus 5 | $0.00112 | $0.00112 |
| Sonnet 5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
actual-cli 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.
What it actually says
GitHub Copilot Instructions
ADR 1: Adopt Modular Library Architecture for Test and Benchmark Infrastructure
- Implement a modular library architecture where core functionality is organized into reusable library modules that can be consumed by benchmarks, tests, and test utilities. This decision establishes a clear separation between production code (src/), test utilities (src/testutil.rs), integration tests (tests/), and performance benchmarks (benches/), with each component importing and utilizing core library modules as needed. The architecture promotes code reuse by centralizing common test utilities in dedicated modules that can be shared across different testing contexts.
ADR 2: Adopt Secure Secrets Management in CI/CD Pipeline
- Implement a dedicated secrets management system integrated into the CI/CD pipeline that separates secret storage from code. This includes using environment variables, encrypted secret stores, or dedicated secrets management services (such as HashiCorp Vault, AWS Secrets Manager, or CI platform-native solutions) to inject credentials at runtime rather than hardcoding them in configuration files or source code. The pattern is consistently applied across CLI commands and testing infrastructure to ensure uniform security practices.
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.

actual-cli copilot-instructions.md is an instructions file published in the GitHub repository actual-software/actual-cli (7 stars, last pushed 5d ago), licensed MIT. It adds 224 tokens to every session, about $0.0011 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.
