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 | $0.01208 | $0.01208 |
| Opus 5.5 | $0.00483 | $0.00483 |
| Sonnet 5.5 | $0.00242 | $0.00242 |
| Haiku 4.5 | $0.00121 | $0.00121 |
Grade A, and why
tesseract 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tesseract — Claude Code Plugin Marketplace
Project Overview
This is a Claude Code plugin marketplace containing multiple independent plugins. Each plugin lives in its own top-level directory and can be installed separately.

Key Conventions
- Plugin isolation: Each plugin is self-contained. Changes to one plugin must not break others.
- Versioning: For relative-path plugins (all plugins in this repo), the version lives only in
.claude-plugin/marketplace.json— NOT inplugin.json. Theplugin.jsonmanifest wins silently and can cause the marketplace version to be ignored. Additionally, bumppyproject.tomlif the plugin has a Python server. - Commands are markdown files in
commands/— they define slash commands users can invoke. - Skills are markdown files at
skills/<name>/SKILL.md— they are auto-invoked by Claude when relevant. - Agents are markdown files in
agents/— they define specialized subagents. - Hooks use
hooks.jsonto register shell scripts for Claude Code lifecycle events. - MCP servers are configured in
.mcp.jsonat the plugin root. - Doc-authoring skills (any skill that writes a doc to
docs/shield/) MUST apply theshield:writing-styleskill to their author-written prose before writing — seeshield/skills/general/writing-style/SKILL.md. This keeps generated docs simple, clear, and concise. It applies to prose only, never to rendered/marker-wrapped sections or JSON sidecars.
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.
