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 | $0.00434 | $0.00434 |
| Opus 5 | $0.00217 | $0.00217 |
| Sonnet 5 | $0.00087 | $0.00087 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
sceptre-mcp-server planning.md 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 4d 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.
What it actually says
Planning Skill
Activate this skill when implementing complex features, architectural changes, or multi-step refactoring.
Planning Process
1. Requirements Analysis
- Understand the feature request completely
- Identify success criteria
- List assumptions and constraints
- Ask clarifying questions if anything is ambiguous
2. Architecture Review
- Analyze existing codebase structure
- Identify affected components and files
- Review similar implementations for patterns to follow
- Consider reusable code and shared utilities
3. Step Breakdown
For each step, define:
- Clear, specific action
- File paths and locations
- Dependencies on other steps
- Estimated complexity (Low/Medium/High)
- Potential risks
4. Implementation Order
- Prioritize by dependencies (do prerequisites first)
- Group related changes to minimize context switching
- Enable incremental testing at each phase

## Success Criteria
- [ ] [Criterion 1]
- [ ] [Criterion 2]
Rules
- Be specific: use exact file paths, function names, variable names
- Think about edge cases and error scenarios
- Minimize changes: extend existing code over rewriting
- Follow existing project conventions
- Each step should be independently verifiable
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.

sceptre-mcp-server planning.md is an instructions file published in the GitHub repository Sceptre/sceptre-mcp-server (0 stars, last pushed 5d ago), licensed Apache-2.0. It adds 434 tokens to every session, about $0.0022 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 2026-09-08.
