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 5.1 | $0.00004 | $0.00262 |
| Opus 5 | $0.00002 | $0.00131 |
| Sonnet 5 | $0.00001 | $0.00052 |
| Haiku 4.5 | $0.00000 | $0.00026 |
Grade A, and why
tool-guideline-index 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 10d 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
Tool Usage Guidelines Index
To prevent common errors when using tools, refer to these detailed guidelines:
File Operations
- File Operations Guidelines - Guidelines for read_file, write_to_file, and list_files
Code Editing
- Code Editing Guidelines - Guidelines for apply_diff
- Search and Replace Guidelines - Guidelines for search_and_replace
- Insert Content Guidelines - Guidelines for insert_content
Common Error Prevention
- apply_diff Error Prevention - Specific guidelines to prevent errors with apply_diff
Key Points to Remember:
- Always include all required parameters for each tool
- Verify file existence before attempting modifications
- For apply_diff, never include literal diff markers in code examples
- For search_and_replace, always include both search and replace parameters
- For write_to_file, always include the line_count parameter
- For insert_content, always include valid start_line and content in operations array
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.

tool-guideline-index is a cursor rule published in the GitHub repository mondweep/remote-mcp-creation-foundation (0 stars, last pushed 1y ago), licensed MIT. It adds 4 tokens to every session and 262 once invoked, about $0.0000 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.
