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 | $0.00056 | $0.03196 |
| Opus 5.5 | $0.00022 | $0.01278 |
| Sonnet 5.5 | $0.00011 | $0.00639 |
| Haiku 4.5 | $0.00006 | $0.00320 |
Grade A, and why
worldsmith-methodology 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Worldsmith Methodology
Rules and structure for documentation-first fiction worldbuilding. This skill provides what cannot be inferred from context alone: the editorial discipline, canonical hierarchy, propagation awareness, and character documentation standards that keep a worldbuilding project internally consistent as it grows.
1. Core Philosophy
Treat documentation as the source of truth for the fictional world. The manuscript is one expression of the world; the docs define it. Docs and manuscript should stay consistent with each other, but recognize that creative work is messy: bidirectional updates happen naturally. A scene might introduce a detail that needs to flow back into the docs, or a doc revision might require manuscript changes. Both directions are legitimate.
When docs and manuscript conflict, the docs are usually right: they represent deliberate editorial decisions. But exercise judgment. Sometimes the manuscript captures a better version of a detail that the docs haven't caught up with. The key discipline is noticing divergence and reconciling it, not enforcing rigid ordering.
All documents are living documents, including the project's CLAUDE.md. As the world evolves through writing, update the docs. As the docs evolve, keep CLAUDE.md current: it is the most frequently read document in any session and serves as the entry point to the entire editorial system. A stale CLAUDE.md undermines every subsequent action.
2. The Document Ecosystem
Worldbuilding projects organize their editorial knowledge across documents that serve specific roles. Think in terms of roles, not filenames: a project might call its timeline doc timeline.md, chronology.md, or history-dates.md. The role matters, not the name. Consult the project's CLAUDE.md for the mapping between roles and files.
Document Roles
- Timeline Authority: The authoritative source for dates, event sequences, character ages at specific points, and day-numbering within chapters. When any other doc or the manuscript disagrees with the timeline on a date or sequence, the timeline wins.
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.

worldsmith-methodology is a skill published in the GitHub repository queelius/claude-anvil (2 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 3,196 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 2026-10-19.
