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.

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 | $0.00067 | $0.06806 |
| Opus 5 | $0.00034 | $0.03403 |
| Sonnet 5 | $0.00013 | $0.01361 |
| Haiku 4.5 | $0.00007 | $0.00681 |
Grade A, and why
superplan 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.

Superplan: Comprehensive Feature Planning
Overview
Superplan creates detailed, executable implementation plans that enable parallel agent execution. Each plan includes everything needed to implement a feature: requirements, architecture, code changes, tests, and acceptance criteria.
When to Use Superplan
- Starting a new feature or epic
- Complex tasks requiring multiple phases
- Tasks that could benefit from parallel execution by multiple agents
- When you need comprehensive documentation of implementation decisions
- When the team needs to understand the full scope before committing
Core Workflow
┌─────────────────────────────────────────────────────────────────────┐
│ SUPERPLAN WORKFLOW │
├─────────────────────────────────────────────────────────────────────┤
│ 1. INTAKE → Gather story/requirements from user │
│ 2. DETECT → Check CLAUDE.md/AGENTS.md first, then scan │
│ (BYPASS codebase scan if docs complete) │
│ 3. INTERVIEW → Ask clarifying questions │
│ 4. RESEARCH → Look up best practices for DETECTED STACK │
│ (BYPASS if CLAUDE.md/AGENTS.md was complete) │
│ 5. EXPLORE → Understand existing codebase patterns │
│ (ALWAYS runs - never bypassed) │
│ 6. REFACTOR ASSESS → Evaluate if refactoring should precede work │
│ 7. ARCHITECT → Design solution with diagrams │
│ 8. PHASE → Break into parallelizable phases + ESTIMATES │
│ 9. DETAIL → Specify code deltas per phase │
│ 10. TEST → Define failing tests per phase (TDD) │
│ 11. DOCUMENT → Write plan to docs/<feature>-plan.md │

CRITICAL: Parallel Execution with Sub-Agents
YOU MUST USE SUB-AGENTS OR PARALLEL TASKS for every parallelizable operation:
What ships with it
6 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.
- 9d ago First seen · 771 lines · 67 tokens per session scan A 999d0435a97f
superplan is a skill published in the GitHub repository asteroid-belt/skulto (50 stars, last pushed yesterday), licensed MIT. It adds 67 tokens to every session and 6,806 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.
