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 | $0.00035 | $0.03781 |
| Opus 5 | $0.00017 | $0.01891 |
| Sonnet 5 | $0.00007 | $0.00756 |
| Haiku 4.5 | $0.00003 | $0.00378 |
Grade A, and why
create-slash-commands 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.
This is a copy
100% identical to create-slash-commands — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

description: Analyze this code for performance issues and suggest optimizations

Analyze the performance of this code and suggest three specific optimizations:
Usage: /optimize
Claude receives the expanded prompt and analyzes the code in context. </quick_start>
<xml_structure> All generated slash commands should use XML tags in the body (after YAML frontmatter) for clarity and consistency.
<required_tags>
<objective> - What the command does and why it matters
<objective>
What needs to happen and why this matters.
Context about who uses this and what it accomplishes.
</objective>
<process> or <steps> - How to execute the command
<process>
Sequential steps to accomplish the objective:
1. First step
2. Second step
3. Final step
</process>
<success_criteria> - How to know the command succeeded
<success_criteria>
Clear, measurable criteria for successful completion.
</success_criteria>
</required_tags>
<conditional_tags>
<context> - When loading dynamic state or files
<context>
Current state: ! `git status`
Relevant files: @ package.json
</context>
(Note: Remove the space after @ in actual usage)
<verification> - When producing artifacts that need checking
<verification>
Before completing, verify:
- Specific test or check to perform
- How to confirm it works
</verification>
<testing> - When running tests is part of the workflow
<testing>
Run tests: ! `npm test`
Check linting: ! `npm run lint`
</testing>
<output> - When creating/modifying specific files
<output>
Files created/modified:
- `./path/to/file.ext` - Description

<intelligence_rules>
Simple commands (single operation, no artifacts):
- Required:
<objective>,<process>,<success_criteria> - Example:
/check-todos,/first-principles
Complex commands (multi-step, produces artifacts):
- Required:
<objective>,<process>,<success_criteria> - Add:
<context>(if loading state),<verification>(if creating files),<output>(what gets created) - Example:
/commit,/create-prompt,/run-prompt
Commands with dynamic arguments:
- Use
$ARGUMENTSin<objective>or<process>tags - Include
argument-hintin frontmatter - Make it clear what the arguments are for
Commands that produce files:
- Always include
<output>tag specifying what gets created - Always include
<verification>tag with checks to perform
Commands that run tests/builds:
- Include
<testing>tag with specific commands - Include pass/fail criteria in
<success_criteria></intelligence_rules> </xml_structure>
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

create-slash-commands is a skill published in the GitHub repository marcusgoll/Spec-Flow (92 stars, last pushed 4mo ago), licensed MIT. It adds 35 tokens to every session and 3,781 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to create-slash-commands, differing in 0 lines, and is treated as a copy.
