What it costs to keep this loaded
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 | $0.00068 | $0.00830 |
| Opus 5 | $0.00034 | $0.00415 |
| Sonnet 5 | $0.00014 | $0.00166 |
| Haiku 4.5 | $0.00007 | $0.00083 |
Grade A, and why
subagents-creator 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 9d 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.

Subagents Creator
This skill provides guidance for defining, using, and improving Claude subagents—the specialized agents that handle specific domains like explore, librarian, oracle, and frontend-ui-ux-engineer.
Quick Start
Delegating Work
When delegating to subagents, use the mandatory 7-section structure:
1. TASK: Atomic, specific goal (one action per delegation)
2. EXPECTED OUTCOME: Concrete deliverables with success criteria
3. REQUIRED SKILLS: Which skill to invoke
4. REQUIRED TOOLS: Explicit tool whitelist (prevents tool sprawl)
5. MUST DO: Exhaustive requirements - leave NOTHING implicit
6. MUST NOT DO: Forbidden actions - anticipate and block rogue behavior
7. CONTEXT: File paths, existing patterns, constraints
Choosing a Subagent
See subagent-types.md for detailed guidance on which subagent to use:
explore: Contextual grep for codebaseslibrarian: Reference search (docs, OSS, web)oracle: Deep reasoning for architecture/complex decisionsfrontend-ui-ux-engineer: Visual UI/UX changes
Defining New Subagents
Only create subagents when: The task domain has distinct tooling, expertise, or patterns that benefit from specialization.
See delegation-patterns.md for:
- Subagent definition templates
- When to create a new subagent vs using existing ones
- Naming and description guidelines
Common Pitfalls
See common-pitfalls.md for:
- Vague delegation prompts and why they fail
- Over-delegating trivial tasks
- Subagent misalignment with task type
- Anti-patterns in agent orchestration
Best Practices
- One action per delegation: Combine tasks in parallel calls, not one call
- Be exhaustive: "MUST DO" and "MUST NOT DO" sections prevent drift
- Background everything: Use
background_taskforexploreandlibrarian - Explicit tool lists: Prevent subagents from using unauthorized tools
- Verify results: Check that delegated work meets expectations before proceeding
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.

subagents-creator is a skill published in the GitHub repository Mineru98/skills-store (13 stars, last pushed 11d ago), licensed MIT. It adds 68 tokens to every session and 830 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 2026-08-30.
