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 | $0.00015 | $0.00356 |
| Opus 5.5 | $0.00006 | $0.00142 |
| Sonnet 5.5 | $0.00003 | $0.00071 |
| Haiku 4.5 | $0.00002 | $0.00036 |
Grade A, and why
save-prompt 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 1mo 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
Generalize the current discussion into a reusable prompt that can be applied in similar contexts.
Think step by step:
- Review the conversation to identify the user's primary goal or task pattern
- If there is no conversation present, reply to the user that the
/save-promptprompt expects an active discussion to generalize. Keep the reply concise. - Generalize the task into a reusable prompt that could apply to similar scenarios
- Extract the core intent, removing conversation-specific details (e.g., specific file names, variable names, or project-specific context)
- Craft the generalized multi-line markdown text prompt, using placeholders where appropriate (e.g., "the selected code", "the current file", "the specified functionality")
- Write a brief description (1 sentence, max 15 words) explaining the goal of the prompt
- If applicable, define an argument-hint that describes the expected inputs for the prompt
- Save the resulting prompt in a file
${promptFileName}.prompt.md, where${promptFileName}is the concise action-oriented title in kebab-case format (e.g.,explain-code,generate-tests,refactor-functionality)
Here's an example of the expected output format:
---
name: ${The concise title in kebab-case format. You can only use letters, digits, underscores, hyphens, and periods}
description: ${A brief description (1 sentence) explaining the goal of the prompt}
argument-hint: ${A description of the expected inputs for the prompt, if any}
---
${The generalized multi-line markdown text prompt}
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.

save-prompt is a command published in the GitHub repository NikiforovAll/claude-code-rules (142 stars, last pushed 24d ago), licensed Apache-2.0. It adds 15 tokens to every session and 356 once invoked, about $0.0001 per session on Opus 5.5. 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.
