Guidelines for comparing binary (ELF) sizes using Rust-based tooling (elf-bloat and asm-annotate) across various platforms to analyze the impact of code changes on footprint.

Guidelines for building Matter examples and chip-tool, and testing examples using chip-tool.

Guidelines for building Matter examples and running tests using Podman with the vscode image in a non-interactive environment.

Essential guidelines instructing AI agents on how to incrementally discover, read, and consult top-level monorepo documentation and example-specific reference guides before altering code or executing test harnesses.

Guidelines for generating clear, concise, and objective GitHub Pull Request descriptions.

Guidelines and instructions for building prerequisite example applications and running python-based integration and certification tests located in `src/python_testing/`. Use this skill to run important regression tests during developement or, when building new example apps, or when there is a need to execute python test scripts or "certification test scripts" or mentions of run_python_test.py and local.py.

Guidelines and common jq/grep/awk queries for investigating ZAP (.zap) and Matter (.matter) files to understand endpoints, clusters, attributes, and commands.

Guidelines for implementing or migrating Matter server clusters to the code-driven pattern using Test-Driven Development (TDD).

Guidelines for implementing or migrating Matter server clusters (code that resides in `src/app/clusters`) using the DefaultServerCluster base class (code-driven data model approach), as opposed to the legacy ZAP/Ember codegen approach.

Step-by-step procedure for migrating a legacy Ember-based Matter server cluster in src/app/clusters/ to the code-driven pattern. Use this skill when converting an existing cluster. All rules from code-driven-cluster-development still apply; this skill adds the migration-specific workflow on top.

Expert guidance for reviewing Python tests in the Matter (connectedhomeip) repository. Use this skill when reviewing changes to tests, specifically targeting common pitfalls in async execution, mocking cluster interactions, and assertion quality.

Guidelines for accessing and reading the Matter specification and test plans. These resources are private and in-progress, so they must be cloned or requested.
