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 | $0.01928 | $0.01928 |
| Opus 5 | $0.00964 | $0.00964 |
| Sonnet 5 | $0.00386 | $0.00386 |
| Haiku 4.5 | $0.00193 | $0.00193 |
Grade A, and why
servo-fetch AGENTS.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 4d 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Instructions for AI coding agents working on servo-fetch. This file complements, not replaces, CONTRIBUTING.md (human-oriented) and skills/servo-fetch/SKILL.md (consumer-oriented). Treat this file as living documentation; update it when conventions change.
Project overview
servo-fetch is a Rust workspace with two crates:
servo-fetch(library): wraps the Servo browser engine to fetch, render, and extract web content. Main entry points:fetch(),crawl()/crawl_each()(streaming),map()(sitemap discovery).servo-fetch-cli(binary): CLI + HTTP API + MCP server. Depends onservo-fetch.
Language bindings live outside the cargo workspace in bindings/python/ (PyO3/maturin) and bindings/node/ (TypeScript wrapper over the CLI; bindings/node is excluded from the workspace).
Toolchain pinned in rust-toolchain.toml; MSRV declared as rust-version in Cargo.toml — do not use features stabilized after the MSRV. Workspace-wide version bumping via [workspace.package].version.
The Servo dependency dominates build time (several minutes on first build, ~30-40 minutes for release). Plan long-running commands accordingly.
Setup and commands
Run these from the workspace root unless noted. Copy-paste ready:
cargo build # Debug build
cargo build --release # Release build (slow)
cargo +nightly fmt --all # Format
cargo +nightly fmt --all -- --check # CI fmt check
cargo clippy --workspace --all-targets -- -D warnings # Lint (pedantic, warnings are errors)
cargo test --workspace # Unit + integration tests (fast)
cargo test -- --ignored # Include Servo-backed e2e tests (slow)
cargo deny check # License + advisory audit
taplo check # TOML lint (install: cargo install taplo-cli --locked)
taplo fmt # TOML format
typos # Spell check
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.

servo-fetch AGENTS.md is an instructions file published in the GitHub repository konippi/servo-fetch (141 stars, last pushed yesterday), licensed Apache-2.0. It adds 1,928 tokens to every session, about $0.0096 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 2026-08-30.
