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 | $0.00609 | $0.00609 |
| Opus 5 | $0.00304 | $0.00304 |
| Sonnet 5 | $0.00122 | $0.00122 |
| Haiku 4.5 | $0.00061 | $0.00061 |
Grade A, and why
Debug-MCP 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.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Python Execution Instructions
Using uv (Recommended)
Run Python files directly:
# Run a Python script
uv run python my_script.py
# Run a module
uv run python -m my_module
# Run tests
uv run pytest
# Run the MCP server
uv run mcp-debug --workspace .
# Run with coverage
uv run pytest --cov=src/mcp_debug_tool --cov-report=html
Using venv (Traditional)
Activate environment first:
# macOS/Linux
source .venv/bin/activate
# Windows
.venv\Scripts\activate
Then run normally:
python my_script.py
python -m my_module
pytest
mcp-debug --workspace .
Why uv run is better
- No activation needed: Works immediately without sourcing scripts
- Consistent environment: Always uses the correct Python and dependencies
- Cross-shell compatibility: Works the same in bash, zsh, fish, PowerShell
- Faster startup: No shell initialization overhead
- Reliable: Prevents "wrong Python" errors
Quick Reference
# Environment setup
uv venv # Create virtual environment
uv pip install -e ".[dev]" # Install project with dev deps
# Common commands
uv run pytest # Run all tests
uv run pytest tests/unit/ -v # Run unit tests verbose
uv run ruff check . # Lint code
uv run ruff check --fix . # Auto-fix lint issues
uv run ruff format . # Format code
uv run python -m mcp_debug_tool.server # Run MCP server
uv run mcp-debug --workspace . # Run MCP server (CLI)
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.

Debug-MCP copilot-instructions.md is an instructions file published in the GitHub repository Kaina3/Debug-MCP (1 stars, last pushed 10mo ago), licensed MIT. It adds 609 tokens to every session, about $0.0030 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.
