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.

What it costs to keep this loaded
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 | $0.00055 | $0.00329 |
| Opus 5 | $0.00028 | $0.00164 |
| Sonnet 5 | $0.00011 | $0.00066 |
| Haiku 4.5 | $0.00006 | $0.00033 |
Grade A, and why
bookmark 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 8d 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
Bookmark
Use when
- Save this link, bookmark this
- Find a previously saved link
- Organize or tag saved URLs
Don't use when
- Just read a webpage (use web_fetch)
- Research a topic (use research)
- Summarize a URL (use summarize)
Instructions
Link management using workspace/bookmarks.json file.
Saving a bookmark:
- Extract URL from message
- Optionally fetch title using web_fetch
- Add to bookmarks.json: { "url": "...", "title": "...", "tags": [], "saved": ISO date }
- Confirm: "🔖 Saved: [title]"
Listing bookmarks:
- Read bookmarks.json
- Format as: 🔖 Title url.com/... Tags: #tag1 #tag2
Finding bookmarks:
- Search by tag: "bookmarks tagged #tech"
- Search by text: "find bookmark about React"
- Return matching entries
Deleting bookmarks:
- Find by URL or title
- Remove from array
- Save updated file
Use read/write tools on "bookmarks.json" for storage.
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.

bookmark is a skill published in the GitHub repository sepivip/SeekerClaw (314 stars, last pushed yesterday), licensed MIT. It adds 55 tokens to every session and 329 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
