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 | $0.00040 | $0.04259 |
| Opus 5 | $0.00020 | $0.02129 |
| Sonnet 5 | $0.00008 | $0.00852 |
| Haiku 4.5 | $0.00004 | $0.00426 |
Grade A, and why
user-defined-command 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 391 lines — stays where its author put it; the contents beside it link to each section on GitHub.
User-Defined Command Skill
This skill enables you to create and edit valid Steward user-defined commands — YAML-based command definitions stored as markdown files in the Steward/Commands folder.
File Format
Each command is a markdown file (.md) containing one or more YAML code blocks. The file can also contain plain text, headings, and other markdown content that can be referenced by system prompts.
After creating or updating a UDC note, re-read the file and check the frontmatter status. If it is invalid, use the status error to fix the YAML and re-read again.
YAML Schema
Command-Level Fields
| Field | Type | Required | Description |
|---|---|---|---|
command_name |
string | Yes | The name (In kebab-case) to invoke the command (e.g., clean-up invoked as /clean-up) |
description |
string | No | Short summary shown in / Help next to the command; omit if not needed |
query_required |
boolean | No | If true, the command requires user input after the prefix. Default: false |
model |
string | No | Default model for all steps (e.g., gpt-4o, gemini-2.5-flash) |
system_prompt |
array of strings | No | Additional system prompts applied to all steps |
tools |
array of strings | No | Super Agent tool names allowed for this command; omit for full set. Use [switch_agent_capacity] for chat-only until the user switches. If more than five tools, activate_tools is added when missing. |
hidden |
boolean | No | If true, the command does not appear in the autocomplete menu |
triggers |
array of trigger objects | No | Automatically execute when file events match criteria |
cli |
object | No | Shell session settings (v2): optional shell executable and whitelist patterns for auto-approved model shell lines (see CLI settings) |
steps |
array of step objects | Yes | The sequence of steps to execute |
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.

user-defined-command is a skill published in the GitHub repository googlicius/obsidian-steward (86 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 4,259 once invoked, about $0.0002 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.
