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 | $0.02672 | $0.02672 |
| Opus 5.5 | $0.01069 | $0.01069 |
| Sonnet 5.5 | $0.00534 | $0.00534 |
| Haiku 4.5 | $0.00267 | $0.00267 |
Grade A, and why
creative-writing-skills AGENTS.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 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.

Repository Overview
A Mars source package providing composable creative writing agents and skills for meridian-cli and Claude Code. Also distributes Claude.ai skill uploads via GitHub Releases.
Key Distinctions
skills/ vs plugin/: skills/ and agents/ are the Mars source: consumed by Claude Code and meridian-cli projects via mars add. plugin/ is Mars-owned output: mars build plugin lowers the source plus the dependency graph into Claude/Codex/Grok, Cursor, and OpenCode trees and writes the marketplace catalogs. Never edit plugin/ or those catalogs by hand; edit the source and rebuild (see Building the plugin). CI fails on a stale or hand-edited tree.
Agents vs skills: Agents are spawned as independent processes (orchestrators, writers, critics). Skills are reference material loaded into agent context (craft knowledge, patterns, conventions). See agents/ and skills/ directories.
Destination sync: Comes from the writing-sync Mars dependency (haowjy/writing-sync), not this repo. Do not vendor those skills here.
Package Management
This repo is both a Mars source package (publishes agents/skills) and a Mars consumer (depends on meridian-base).
mars check # Validate package, schema, and plugin output state
mars version patch --push # Bump version, rebuild plugin/, promote CHANGELOG, commit, tag, push
Version lives in mars.toml under [package]. Tags trigger CI releases. Release with Mars 0.20.6 or newer: older Mars leaves plugin/.mars-plugin.json different from a rebuild (mars-agents#239), which fails CI's rebuild-and-diff check on the tag.
Version sync: mars version bumps mars.toml, rebuilds plugin/ and the root catalogs at the new version, and commits them together, so the plugin version never lags mars.toml.
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.
