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 | $0.01582 | $0.01582 |
| Opus 5 | $0.00791 | $0.00791 |
| Sonnet 5 | $0.00316 | $0.00316 |
| Haiku 4.5 | $0.00158 | $0.00158 |
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 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.

Repository Overview
A Mars source package providing composable creative writing agents and skills for Meridian and Claude Code. Also distributes Claude.ai skill uploads via GitHub Releases.
Key Distinctions
skills/ vs cw/skills/: skills/ is the Mars source: consumed by Claude Code projects via mars add. cw/skills/ holds the Claude.ai / plugin distribution — genericized copies with Meridian-specific references removed. Edit skills/ first, then resync cw/ (see Syncing the cw/ distribution). CI fails on drift, so this is not optional.
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.
Package Management
This repo is both a Mars source package (publishes agents/skills) and a Mars consumer (depends on meridian-base).
meridian mars check # Validate package structure and frontmatter
meridian mars sync # Install dependencies into .agents/
meridian mars version patch # Bump version, commit, tag
Version lives in mars.toml under [package]. Tags trigger CI releases.
Version sync: mars version patch bumps mars.toml. The sync script (sync_cw_skills.py) auto-syncs the version into both .claude-plugin/marketplace.json (metadata.version) and cw/.claude-plugin/plugin.json (version), staging the files for the in-flight commit. This runs in all modes (check, lint, apply) so the pre-commit hook catches drift.
Meridian session roots: Meridian spawns resolve MERIDIAN_TASK_DIR for the
checkout where source work happens, but MERIDIAN_PROJECT_DIR stays anchored to
the session control root for state, profiles, and context. Nested
meridian ... commands use project-root resolution, so CWD alone may not target
this package. For package releases, pass the package root explicitly:
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.
