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 | $0.00425 | $0.00425 |
| Opus 5.5 | $0.00170 | $0.00170 |
| Sonnet 5.5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
contentstack-agent-skills CLAUDE.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 25d 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
Contentstack Skills
This repository bundles Contentstack agent skills. Every skill lives once in skills/<slug>/SKILL.md (the Agent Skills format) and is distributed to Claude Code, claude.ai, Cursor, Codex, GitHub Copilot, Gemini CLI and the skills CLI through the manifests at the repo root. There are no generated copies.
Editing skills
namemust equal the folder name (lowercase, hyphens, max 64 chars).descriptionsays what the skill does and includes "Use when …" triggers, max 1024 chars. This is the only text agents see before loading a skill, so put routing cues here.- Keep
SKILL.mdfocused; move long material intoreferences/and link it with a relative path. - When adding a skill, add its row to the table in
README.md, and add adocs/skills/<slug>.mdpage linked fromdocs/skills/index.md. - Run
node scripts/validate.mjsbefore committing. CI runs it on every PR.
Releasing
Bump version to the same value in .claude-plugin/plugin.json, .claude-plugin/marketplace.json, .cursor-plugin/plugin.json, plugin.json and gemini-extension.json. Installed Claude Code plugins only update when the version changes. Add a section to CHANGELOG.md for the release.
Contentstack references
When a skill needs up-to-date product or API details, consult:
- developers.contentstack.com — SDKs, CLIs, API references
- contentstack.com/docs — product documentation
- contentstack.com/academy — training and learning paths
- contentstack.com/explorer — free sandbox accounts for testing
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.
