A
architectural-refactor
architectural-refactor
petekp / agent-skills

Execute architectural refactoring from an assessment document with deterministic, chunked operations and aggressive verification at every step. Use when you have an architectural assessment, clean architecture review, refactoring recommendations, or seam-ripper output and need to actually perform the refactoring safely. Also use when asked to "refactor based on this assessment", "execute these architectural recommendations", "fix architectural drift", "refactor in chunks", or any request to systematically restructure a codebase according to a plan. Designed specifically to prevent the kind of agent drift that causes architectural problems in the first place.

audit-security
audit-security
kensaurus / skills

author-modeladvisor-checks
matlab / simulink-agentic-toolkit

Author or upgrade Model Advisor checks for Simulink and System Composer models. Covers the full lifecycle: guideline authoring, check specification, Model Advisor check implementation, and qualification testing. Use when creating new checks (edit-time, standard batch, config-parameter, auto-fix), converting legacy StyleOne/StyleTwo/StyleThree checks to modern DetailStyle, creating a guideline for modeling, enforcing a modeling rule, or testing/qualifying a check. Triggers on any modeling constraint (e.g., "blocks shall...", "signals must match...", "parameters shall be set to...").

Testing & quality39
B
base-in-reality
base-in-reality
dhanesh / agent-skills

Research-grounded, read-only audit that validates a repository's codebase, architecture, and business logic against real-world knowledge from authoritative sources (arxiv, PubMed, Google Scholar, JSTOR, OpenAlex, Crossref, Semantic Scholar) plus standards bodies (NIST, IETF/RFC, OWASP, ISO, sector regulators). Use when you want an audit that flags algorithms, architectural choices, or business rules violating established norms, standards, or best practices — e.g. 'is our APR calculation correct per lending norms?', 'does our crypto follow NIST?', 'is this consensus approach sound?' — each finding tied to a real, fetched citation. Extracts falsifiable claims across algo/arch/biz layers, routes each to the right source class, verifies against fetched evidence, and adversarially refutes before reporting; emits a severity-graded cited report with UNCONFIRMED for anything ungrounded. Not a linter, SAST, or CVE scanner — it reasons about norms, not syntax.

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

guided-review
guided-review
jimhigson / guided-review

Build an ordered, locally-served HTML reading order for a large commit, PR (by number, branch or github url - the repo need not be checked out here), working tree or conflict resolution, grouped by theme, with each file's diff inline in an editable Monaco editor (2-way, or 3-way current | resolution | incoming for a conflict), per-line review notes, and a pan/zoom compare viewer for changed images. Use when a commit/PR is too large to read file-by-file in git-log order and the user wants a guided path through it; to review changed Playwright screenshot baselines / any image diffs visually (the scripted snapshots-only mode needs no authoring at all); and offer it, unasked, straight after you (or another agent) resolve non-trivial merge, rebase, cherry-pick or revert conflicts - before the operation is continued or committed - so the user can check the resolution against both sides.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
