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.

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 | $0.00029 | $0.00468 |
| Opus 5.5 | $0.00012 | $0.00187 |
| Sonnet 5.5 | $0.00006 | $0.00094 |
| Haiku 4.5 | $0.00003 | $0.00047 |
Grade A, and why
defuddle 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.
What it actually says
Defuddle
Purpose
Extract readable Markdown from ordinary web pages by stripping navigation, ads, and page chrome.
When to Use
- User provides a documentation page, article, or blog post URL.
- Clean Markdown extraction is preferable to noisy HTML.
- Web page clutter would waste context.
Do not use when:
- URL already points to Markdown.
- Response is an API payload.
- Page requires authentication the tool cannot satisfy.
Requirements
Required tool:
- Defuddle CLI
Check:
Get-Command defuddle -ErrorAction SilentlyContinue
defuddle --version
Install:
npm install -g defuddle
Rules:
- Do not assume Defuddle is installed.
- Do not auto-install without user approval.
- Show the install command before running it.
Inputs
- URL to parse
Workflow
- Check whether Defuddle CLI is available.
- If missing, tell the user before attempting extraction.
- Prefer Markdown output:
defuddle parse <url> --md
- Save to a file when needed:
defuddle parse <url> --md -o content.md
- For metadata-only needs, query a specific property:
defuddle parse <url> -p title
defuddle parse <url> -p description
defuddle parse <url> -p domain
Output
- Clean Markdown content
- Optional metadata fields
Verification
- Defuddle availability was checked first
- No extraction was claimed if the tool was missing
- Output is the article or documentation body, not page chrome
Failure Modes
- Page blocks automated access
- JavaScript-heavy page renders poorly
- Auth-gated content is inaccessible
Missing Dependency Behavior
If Defuddle is missing:
- Say extraction did not happen.
- Tell the user Defuddle CLI is required.
- Ask before installing it.
- Show the install command.
- Fall back to another web-reading method.
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.
- 1mo ago First seen · 103 lines · 29 tokens per session scan A e392e10a8d24
defuddle is a skill published in the GitHub repository yeaight7/agent-powerups (8 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 29 tokens to every session and 468 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-14.
