Project instructions for Isartor, including its commands, architecture, and coding conventions. Isartor is a software project built with Rust, a programming language.

In plain words
What is it for?

Why use it?
They give a coding agent the project-specific information needed to build, test, format, lint, and benchmark the code correctly.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is isartor-ai/Isartor's own configuration. It tells GitHub Copilot how to work on Isartor itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Isartor configures →

Token cost

What 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.

Security

Grade A, and why

Isartor 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 8d 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.

Copilot Instructions for Isartor

Build, test, and lint commands

  • Use cargo build for a local build and cargo build --release or make build for a release build.
  • Run the full test suite with cargo test --all-features or make test.
  • Run formatting and lint checks the same way CI does:
    • cargo fmt --all -- --check
    • cargo clippy --all-targets --all-features -- -D warnings
  • Run a single test by targeting the integration-test binary that owns it, for example:
    • cargo test --test scenario_suite deflection_rate_at_least_60_percent -- --nocapture
    • cargo test --test integration_suite body_survives_all_middleware -- --nocapture
    • cargo test --test unit_suite exact_cache_miss_then_hit -- --nocapture
    • cargo test --test integration_test redis_exact_cache_round_trip -- --ignored --nocapture
  • Run Criterion benches with the explicit bench target, for example:
    • cargo bench --bench cache_latency
    • cargo bench --bench e2e_pipeline
  • Run the benchmark harness with:
    • make benchmark
    • make benchmark-dry-run
    • python3 benchmarks/run.py --url http://localhost:8080 --input benchmarks/fixtures/faq_loop.jsonl --requests 500
  • Development setup in CONTRIBUTING.md expects Rust 1.75+ and notes Docker for integration-test workflows.
  • Update tests in tests/, targeting the owning integration-test binary (unit_suite, integration_suite, scenario_suite, or integration_test) rather than assuming per-file test targets.
  • Treat README.md as the public feature list and top-level product entry point.
  • For any implementation ticket that changes behavior, capabilities, supported providers/tools, CLI/API surfaces, configuration, or UX, update the affected documentation in the same change:
    • README.md feature list and user-facing capability callouts
    • supplementary docs in docs/
    • published docs in docs-site/src/
  • If the implementation changes system structure, request flow, supported surfaces, deployment model, routing strategy, cache semantics, or other lasting technical trade-offs, also update:
    • docs/architecture-decisions.md
    • docs-site/src/concepts/architecture-decisions.md
    • docs-site/src/concepts/architecture.md
  • Do not defer these documentation or architecture updates to a follow-up ticket when the implementation itself is shipping now.

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.
