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 | $0.00051 | $0.01306 |
| Opus 5 | $0.00026 | $0.00653 |
| Sonnet 5 | $0.00010 | $0.00261 |
| Haiku 4.5 | $0.00005 | $0.00131 |
Grade A, and why
web-browsing 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 11d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Browsing
The web is a firehose. The skill is not in finding information — it is in finding the right information and knowing when you have enough.
Tenets
- Search is iterative. The first query rarely returns the best result. Every page you read teaches you better terms for the next query.
- One query, one intent. A query that asks two questions answers neither well. Split "Python async vs sync performance and Django ORM optimisation" into two searches.
- Source authority matters. A blog post from 2019 is not evidence for a 2026 claim. A corporate marketing page is not an independent review. Factor the source into every fact you extract.
- Corroborate before citing. A single source is a lead, not a fact. Two independent sources agreeing is a fact. Three is confirmation.
Leading words
- Scout — A broad, exploratory search to map the territory. Before you commit to deep reading, know what exists. Scout searches use wide queries and skim results.
- Sift — Evaluate and filter what you found. A result's rank does not equal its value. Sift by relevance, authority, freshness, and independence before deciding what to fetch.
- Corroborate — Cross-reference each claim against a second independent source. A claim that cannot be corroborated is a claim you qualify ("According to one source…").
Phases
PHASE 1: Plan
Completion criterion: the question(s) to search for are written down, each as a separate query string, and the appropriate search backend is chosen.
- Decompose the user's request into independent questions. Each question gets its own search.
- For each question, choose the backend by the nature of the answer needed (see BACKENDS.md).
- If the question refers to a specific known URL (docs page, blog post, GitHub repo), skip directly to Phase 4 (Extract) — no search needed.
PHASE 2: Scout
Completion criterion: search results returned for every question. At least one result per question looks promising enough to fetch.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

web-browsing is a skill published in the GitHub repository sagar-shirwalkar/collibra-atlas (0 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 51 tokens to every session and 1,306 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
