Edit and improve articles by restructuring sections, improving clarity, and tightening prose. Use when user wants to edit, revise, or improve an article draft.

Use when the user wants to turn one or more Entire-tracked sessions, checkpoints, or repeated agent workflows into a reusable agent skill.

Plan phase of RPI methodology. Consumes research artifact or topic and produces compact implementation plan with test specs and Agent Context blocks. Use after research or to start planning a non-trivial feature.

Plan phase of RPI methodology. Consumes research artifact or topic and produces compact implementation plan with test specs and Agent Context blocks. Use after research or to start planning a non-trivial feature.

Transforms a research artifact or feature topic into a compact implementation plan with task breakdown, dependency mapping, test specifications, and acceptance criteria. Use when planning a non-trivial feature, designing architecture, writing a technical spec, or breaking down implementation steps before coding. Produces a phased plan with Agent Context blocks and a beads task graph for incremental execution.

Use when an issue needs its complexity declared — proposing a rating from the issue body alone and getting the owner to confirm or amend it, or backfilling a rating onto an existing unrated issue. Invoked by new-feat at issue-creation time; also the backfill path for issues opened before the label existed.

Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.

Start a new OpenSpec change using the experimental artifact workflow. Use when the user wants to create a new feature, fix, or modification with a structured step-by-step approach.

Audits Brand Studio and Offer Studio schema, models, extraction prompts, and UI forms against 10 marketing frameworks to find gaps, duplicates, and misaligned concepts. Produces an actionable checklist (CRITICAL/HIGH/MEDIUM) that an agent can execute. Supports three audit modes: Brand Studio (marca completa), Offer Studio (sistema de ofertas), or a specific offer type (e.g., COHORT_BASED_COURSE, PRODUCTIZED_SERVICE). Use this skill when the user mentions auditing, reviewing, or improving Brand Studio, Offer Studio, brand schema, offer schema, brand extraction, offer completeness, or anything related to validating whether the system captures brand/offer data correctly. Also trigger when the user asks about marketing framework coverage, missing fields, SDR data readiness, or wants to audit a specific offer type.

Revise prose at the sentence and word level while preserving voice, meaning, source accuracy, and useful weirdness. Use when the structure is stable and the user asks for a line edit, polish, tightening pass, or usable rewrite.

Use for persistent, visual, short-loop CAD modeling with cad.open, cad.add_part, cad.edit_part, cad.place, cad.import, cad.delete, cad.look, cad.inspect, Host-owned CAD Review, and cad.export.

Use when standard mechanical parts, fasteners, bearings, V-slot rails, T-nuts, wheels, or linear-motion parts are needed in Build123d CAD, and always before modeling a screw into a 3D-printed part — printed screw joints must come from this skill's kit, never hand-modeled.

Use when a development board, SBC, MCU module, or board-level enclosure constraint must be resolved for hardware or CAD design.

Review a project's archival_memory and propose promotions, near-duplicate merges, and stale cleanup for user approval. Read-only — applies nothing.

Integrate with Google's Gemini CLI for delegating tasks to Gemini. Use when you need an alternative AI perspective, Google Search grounding, parallel task execution, or want to leverage Gemini's 1M token context window. Enables "Claude calling Gemini" patterns for diverse AI collaboration.

Diagnose and fix MCP configuration/runtime issues across supported integrations using agents CLI checks.

Use this skill when the user wants to review code, audit a pull request, check code quality, find bugs, or get feedback on implementation.

Learn about Agent Skills - how AI agents use skills, create new skills, and understand skill discovery in real-time. Use when user asks about skills, wants to create a skill, or wants to understand how Claude uses skills.

Determine which parts of the C codebase use Rust-defined C symbols. Use this when you want to understand which C code files may be impacted by changes to a Rust FFI crate.

Guidance on implementing the Data Layer using Repository pattern, Room (Local), and Retrofit (Remote) with offline-first synchronization.
