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 | $0.01793 | $0.01793 |
| Opus 5 | $0.00897 | $0.00897 |
| Sonnet 5 | $0.00359 | $0.00359 |
| Haiku 4.5 | $0.00179 | $0.00179 |
Grade A, and why
webshift 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 5d 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 — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Communication
Chat in Italian, develop and document in English.
MANDATORY Session Initialization & Tooling
At the start of every session, run Serena's onboarding process to activate the MCP integration and get access to all LSP-powered tools (code navigation, symbol search, references, diagnostics, etc.). Do this before any coding task — it ensures the full toolset is available and the project context is loaded correctly.
Once Serena is active, always prefer its tools over CLI alternatives.
Project
Native Rust port of mcp-webshift (Python). Denoised web search library and MCP server. Two crates in a workspace:
webshift— library crate (crates.io). Public API:clean(),fetch(),query(),Config.webshift-mcp— binary crate (crates.io). MCP server over stdio. Installs asmcp-webshift.robot— internal dev tool (not published).bump,test,promote,unpromote,publish.
Reference implementation
The Python source lives in ../mcp-webshift/src/mcp_webshift/. Key files to reference
when porting:
scraper/cleaner.py— lxml XPath cleaning + text sterilizationscraper/fetcher.py— httpx concurrent fetcher, streaming, UA rotation, retrytools/query.py— full search pipelinetools/fetch.py— single page fetchconfig.py— Pydantic config with env/toml/CLI resolutionbackends/— 5 search backend implementationsllm/— OpenAI-compatible client, expander, summarizerutils/reranker.py— BM25 + LLM rerankingutils/url.py— sanitize, dedup, binary filter

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.

webshift CLAUDE.md is an instructions file published in the GitHub repository x-hannibal/webshift (7 stars, last pushed 3mo ago), licensed MIT. It adds 1,793 tokens to every session, about $0.0090 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.
