Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00066 | $0.00289 |
| Opus 5.5 | $0.00026 | $0.00116 |
| Sonnet 5.5 | $0.00013 | $0.00058 |
| Haiku 4.5 | $0.00007 | $0.00029 |
Grade A, and why
office-documents-official 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 today.
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
Office and PDF files: use Anthropic's document-skills
caddis does not include skills for Word (.docx), PDF, PowerPoint (.pptx) or Excel (.xlsx) files.
These skills belong to Anthropic. Anthropic publishes them as the document-skills plugin.
Install (Claude Code)
/plugin marketplace add anthropics/skills
/plugin install document-skills@anthropic-agent-skills
Source: https://github.com/anthropics/skills (see its README, section "Claude Code").
What to do
- If the plugin is installed, use its
docx,pdf,pptxorxlsxskill for the file type. Do not work from this note. - If the plugin is not installed, tell the user the two commands above. Then ask if they want to install it first.
- If the user cannot install it, say what you can do without it. For example, write the content as Markdown and let the user convert it.
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.
