  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads clippy-advanced automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

clippy-advanced - Advanced Clippy Configuration

Advanced Clippy configuration for comprehensive Rust linting, including custom rules, lint categories, disallowed methods, and IDE integration.

When to Use This Skill

Use this skill when...Use another tool instead when...
Configuring Clippy lint rulesFormatting code (use rustfmt)
Setting up CI linting for RustBuilding/compiling (use cargo build)
Customizing clippy.tomlRunning tests (use cargo test)
Enforcing code standardsManaging dependencies (use cargo add)

Installation

# Clippy is included with rustup
rustup component add clippy

# Verify installation
cargo clippy --version

# Update clippy with rust toolchain
rustup update

Basic Usage

# Run clippy on current project
cargo clippy

# Run on all targets (lib, bins, tests, examples, benches)
cargo clippy --all-targets

# Run with all features enabled
cargo clippy --all-features

# Run on workspace
cargo clippy --workspace --all-targets --all-features

# Show detailed lint explanations
cargo clippy -- -W clippy::all -A clippy::pedantic

# Treat warnings as errors
cargo clippy -- -D warnings

Recommended Cargo.toml Configuration

[workspace.lints.clippy]
# Deny correctness issues (likely bugs)
correctness = "deny"
complexity = "warn"
perf = "warn"
style = "warn"
suspicious = "warn"

# Enable pedantic but allow some noisy lints
pedantic = "warn"
must_use_candidate = "allow"
missing_errors_doc = "allow"

# Enable some restriction lints selectively
clone_on_ref_ptr = "warn"
dbg_macro = "warn"
print_stdout = "warn"
todo = "warn"
unimplemented = "warn"
unwrap_used = "warn"

# Enable nursery lints (experimental)
use_self = "warn"

clippy.toml Essential Settings

Create clippy.toml in project root for thresholds and disallowed items:

cognitive-complexity-threshold = 15
too-many-lines-threshold = 100
too-many-arguments-threshold = 5

disallowed-methods = [
  { path = "std::env::var", reason = "Use std::env::var_os for better Unicode handling" },
  { path = "std::process::exit", reason = "Use Result propagation instead" },
]

disallowed-names = ["foo", "bar", "baz"]

Lint Suppression

// Function-level
#[allow(clippy::too_many_arguments)]
fn complex_function(a: i32, b: i32, c: i32, d: i32, e: i32, f: i32) {}

// Module-level (src/lib.rs)
#![warn(clippy::all)]
#![warn(clippy::pedantic)]
#![deny(clippy::unwrap_used)]
#![allow(clippy::module_name_repetitions)]

// Inline
#[allow(clippy::cast_possible_truncation)]
let x = value as u8;

This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
