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 | $0.00066 | $0.01410 |
| Opus 5 | $0.00033 | $0.00705 |
| Sonnet 5 | $0.00013 | $0.00282 |
| Haiku 4.5 | $0.00007 | $0.00141 |
Grade A, and why
sub-agents 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 today.
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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sub-Agents - External CLI AI Task Delegation
Spawns external CLI AIs (Codex, cursor-agent, codex, gemini) as isolated sub-agents with dedicated context.
Resources
- run_subagent.py - Main execution script
- codex.md - Codex-specific setup (permissions, timeout)
Script Path: Use absolute path {SKILL_DIR}/scripts/run_subagent.py where {SKILL_DIR} is the directory containing this SKILL.md file.
CLI-Specific Notes
Check the corresponding reference for your environment:
- Codex: Read references/codex.md BEFORE first execution
Interpreting User Requests
Extract parameters from user's natural language request:
| Parameter | Source |
|---|---|
| --agent | Agent name from user request (see selection rules below) |
| --prompt | Task instruction part (excluding agent specification) |
| --cwd | Current working directory (absolute path) |
Agent Selection Rules (when user doesn't specify agent name):
- Run
--listto get available agents - 0 agents: Inform user no agents available, show setup instructions (see Agent Definition Format)
- 1 agent: Auto-select without asking
- 2+ agents: Show list with descriptions, ask user to choose
Example:
"Run code-reviewer on src/"
→ --agent code-reviewer --prompt "Review src/" --cwd $(pwd)
When to Use This Skill
Use sub-agent when ANY of these apply:
- Complex multi-step task (isolated context prevents interference)
- Parallel investigation (multiple agents can run simultaneously)
- Task needs fresh context (sub-agent starts without conversation history)
- Specialized agent definition exists (leverage pre-defined expert prompts)
Important: Permission and Timeout
This script executes external CLIs that require elevated permissions.
Before first execution:
- Request elevated permissions via your CLI's tool parameters
- Set tool timeout to match
--timeoutargument (default: 600000ms)
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.
- today First seen · 178 lines · 66 tokens per session scan A 6a526b9cd1ed
sub-agents is a skill published in the GitHub repository opencue/cuecards (5 stars, last pushed yesterday), licensed MIT. It adds 66 tokens to every session and 1,410 once invoked, about $0.0003 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 2026-09-03.
