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 | $0.00045 | $0.01308 |
| Opus 5.5 | $0.00018 | $0.00523 |
| Sonnet 5.5 | $0.00009 | $0.00262 |
| Haiku 4.5 | $0.00005 | $0.00131 |
Grade A, and why
planning 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 2mo 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.

Planning Skill
Overview
This skill provides comprehensive planning workflows for features and system changes. It focuses on the research and clarification phase - gathering context, exploring architecture, and asking good questions before spec generation.
When to Use This Skill
Use this skill when:
- In planning/plan mode (auto-trigger if possible)
- User says: "plan this", "research this feature", "help me understand"
- User asks: "what do I need to know before implementing X?"
- Before generating specs with
/cmd:generate-spec - Need to explore codebase patterns and architecture
Core Workflow
1. Research Phase
- Explore codebase for similar existing features
- Identify which domain/area this belongs in
- Locate related types, schemas, services, routes
- Check test patterns in relevant areas
- Review database models (if applicable)
- Use
references/research-checklist.mdfor systematic exploration
2. Context Gathering
- Internal docs: Check
.agent/docs/for relevant patterns - CLAUDE.md: Review project conventions and rules
- context7 MCP (if available): Fetch external library docs
- Check for
mcp__context7__*tools - Use for React, Fastify, Prisma, etc. documentation
- Fall back to WebFetch/WebSearch if not available
- Check for
- See
references/context-sources.mdfor detailed guidance
3. Clarification (If Needed)
Ask clarifying questions ONE AT A TIME if implementation approach is unclear:
- Don't use the Question tool
- Use this template:
**Question**: [Your question] **Suggestions**: 1. [Option 1] (recommended - why) 2. [Option 2] 3. Other - user specifies - See
references/clarification-questions.mdfor examples and templates
4. Complexity Assessment
- Estimate file count and scope
- Identify cross-cutting concerns
- Assess if new patterns needed or extending existing
- Determine context requirements for implementation
- Flag if complexity suggests breaking into smaller features
- See
references/complexity-assessment.mdfor detailed rubric
What ships with it
4 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.

planning is a skill published in the GitHub repository jnarowski/agentcmd (18 stars, last pushed 10mo ago), licensed MIT. It adds 45 tokens to every session and 1,308 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-01.
