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 | $0.01216 | $0.01216 |
| Opus 5 | $0.00608 | $0.00608 |
| Sonnet 5 | $0.00243 | $0.00243 |
| Haiku 4.5 | $0.00122 | $0.00122 |
Grade A, and why
copilot-ralph 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 yesterday.
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.

GitHub Copilot Instructions for Ralph
This file provides quick reference instructions for GitHub Copilot when working on Ralph. For comprehensive details, see AGENTS.md.
Project Overview
Ralph is an iterative AI development loop tool built in Go, using:
- CLI: Cobra for commands
- TUI: Bubble Tea for terminal UI
- AI: GitHub Copilot SDK
- Testing: testify for assertions
Key Principles
1. Spec-Driven Development
- Read specs first: All specs are in
/specs/directory - Implement per spec: Follow specifications exactly
- Update spec first: If requirements change, update spec before code
2. Code Style
See Go-specific instructions for detailed Go conventions including:
- No
elsestatements - Use early returns - Error wrapping - Always use
%w - Table-driven tests - Multiple test cases in one test
- Bubble Tea patterns - Model-View-Update (MVU)
- Package documentation - Document all exported symbols
3. Architecture
CLI Layer (cmd/ralph, internal/cli)
↓
TUI Layer (internal/tui)
↓
Core Layer (internal/core)
↓
SDK Layer (internal/sdk)
Dependency Rules:
- CLI depends on TUI and Core
- TUI depends on Core
- Core depends on SDK
- SDK has no internal dependencies
- No circular dependencies
4. Bubble Tea Pattern
All TUI components use Model-View-Update. See golang.md for detailed patterns:
- Model - State and data
- Init - Initialize and return initial commands
- Update - Handle messages and update state (no
elsestatements!) - View - Render to string
5. Testing
- Unit tests: Test individual functions
- Mock dependencies: Use interfaces
- Table-driven: Multiple test cases in one test
- Integration tests: Guard with environment checks

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.

copilot-ralph copilot-instructions.md is an instructions file published in the GitHub repository JanDeDobbeleer/copilot-ralph (55 stars, last pushed 7mo ago), licensed MIT. It adds 1,216 tokens to every session, about $0.0061 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.
