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 | $0.00024 | $0.00165 |
| Opus 5 | $0.00012 | $0.00082 |
| Sonnet 5 | $0.00005 | $0.00033 |
| Haiku 4.5 | $0.00002 | $0.00016 |
Grade A, and why
writing-plans 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 10d 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
Writing Plans Superpower
Create actionable, modular, and verifiable implementation plans.
Guidelines for Plans
- Explicit Scope: Clearly list what is in-scope and what is explicitly out-of-scope.
- File Level Diffs: Break down changes by component and specify exact files being created, modified, or deleted.
- Dependencies First: Order steps logically so lower-level models and clients are implemented before higher-level ViewModels and UI.
- Verification Criteria: Every phase must contain automated and manual verification steps.
- Open Questions: Surface design tradeoffs, potential breaking changes, or ambiguities upfront.
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.

writing-plans is a skill published in the GitHub repository kareemessam09/Openship-App (11 stars, last pushed 15d ago), licensed Apache-2.0. It adds 24 tokens to every session and 165 once invoked, about $0.0001 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.
