Explore requirements and approaches through collaborative dialogue before writing a right-sized requirements document and planning implementation. Use for feature ideas, problem framing, when the user says 'let's brainstorm', or when they want to think through options before deciding what to build. Also use when a user describes a vague or ambitious feature request, asks 'what should we build', 'help me think through X', presents a problem with multiple valid solutions, or seems unsure about scope or direction — even if they don't explicitly ask to brainstorm.
Refresh stale or drifting learnings and pattern docs in docs/solutions/ by reviewing, updating, consolidating, replacing, or deleting them against the current codebase. Use after refactors, migrations, dependency upgrades, or when a retrieved learning feels outdated or wrong. Also use when reviewing docs/solutions/ for accuracy, when a recently solved problem contradicts an existing learning, when pattern docs no longer reflect current code, or when multiple docs seem to cover the same topic and might benefit from consolidation.
Use when creating, editing, auditing, or fixing bundled Systematic skills, especially when authoring SKILL.md files, adding skill reference files, resolving content-integrity frontmatter failures, or deciding which Systematic conventions apply beyond the general writing-skills guidance.
Use when dispatching parallel or serial subagents in OpenCode, coordinating multi-unit plan execution, synthesizing results from independent subagent runs, or handling subagent failure and retry. Triggers on requests to run tasks in parallel, divide work across subagents, orchestrate a pipeline of dependent steps, or coordinate multiple agents without shared-file conflicts.
Create structured plans for any multi-step task -- software features, research workflows, events, study plans, or any goal that benefits from structured breakdown. Also deepen existing plans with interactive review of sub-agent findings. Use for plan creation when the user says 'plan this', 'create a plan', 'write a tech plan', 'plan the implementation', 'how should we build', 'what's the approach for', 'break this down', 'plan a trip', 'create a study plan', or when a brainstorm/requirements document is ready for planning. Use for plan deepening when the user says 'deepen the plan', 'deepen my plan', 'deepening pass', or uses 'deepen' in reference to a plan.

Triggers on "optimize permissions", "reduce permission prompts", "allowlist commands", "too many permission prompts", "permission fatigue", "permission setup", or complaints about clicking approve too often.
Commit, push, and open a PR with an adaptive, value-first description. Use when the user says "commit and PR", "push and open a PR", "ship this", "create a PR", "open a pull request", "commit push PR", or wants to go from working changes to an open pull request in one step. Also use when the user says "update the PR description", "refresh the PR description", "freshen the PR", or wants to rewrite an existing PR description. Produces PR descriptions that scale in depth with the complexity of the change, avoiding cookie-cutter templates.

Run browser tests on pages affected by current PR or branch
Use when creating durable work items, managing todo lifecycle, or tracking findings across sessions in the file-based todo system
Use when building or reviewing any frontend interface. Covers the full design lifecycle: context detection, pre-build planning, design laws (OKLCH color, theme forcing function, layout rhythm, absolute bans on AI-slop patterns), implementation guidance, and visual verification. Use for landing pages, dashboards, components, or any web UI where design quality matters.
Execute work efficiently while maintaining quality and finishing features
Capture solved problems as categorized documentation with YAML frontmatter for fast lookup
Use when reviewing pending todos for approval, prioritizing code review findings, or interactively categorizing work items
Use when starting any conversation - establishes how to find and use skills, requiring skill tool invocation before ANY response including clarifying questions
Use when orchestrating multi-agent swarms, coordinating parallel code reviews, creating pipeline workflows with dependencies, building self-organizing task queues, or any task benefiting from divide-and-conquer patterns.
Use when implementing any feature or bugfix, before writing implementation code
Review requirements or plan documents using parallel persona agents that surface role-specific issues. Use when a requirements document or plan document exists and the user wants to improve it.
Generate and critically evaluate grounded improvement ideas for the current project. Use when asking what to improve, requesting idea generation, exploring surprising improvements, or wanting the AI to proactively suggest strong project directions before brainstorming one in depth. Triggers on phrases like 'what should I improve', 'give me ideas', 'ideate on this project', 'surprise me with improvements', 'what would you change', or any request for AI-generated project improvement suggestions rather than refining the user's own idea.
Create, edit, comment on, share, and run human-in-the-loop iteration loops over markdown documents via Proof's web API. Use when asked to "proof", "share a doc", "create a proof doc", "comment on a document", "suggest edits", "review in proof", "iterate on this doc in proof", "HITL this doc", "sync a Proof doc to local", when a caller needs an HITL review loop over a local markdown file (e.g., ce-brainstorm, ce-ideate, or ce-plan handoff), or when given a proofeditor.ai URL. Prefer this skill for any workflow whose output is a Proof URL or that uses a Proof doc as the review surface, even when not named explicitly.
[BETA] Execute work with external delegate support. Same as ce:work but includes experimental Codex delegation mode for token-conserving code implementation.
Use when importing, converting, or syncing agent, skill, or command definitions from CEP or other Claude Code-format sources into the Systematic plugin for OpenCode. Triggers on "import from CEP", "sync upstream", "convert CC definition", "add agent/skill/command from upstream", or when updating existing bundled definitions from upstream sources.
Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.
Run comprehensive agent-native architecture review with scored principles
Stress-test an existing implementation plan and selectively strengthen weak sections with targeted research. Use when a plan needs more confidence around decisions, sequencing, system-wide impact, risks, or verification. Best for Standard or Deep plans, or high-risk topics such as auth, payments, migrations, external APIs, and security. For structural or clarity improvements, prefer document-review instead.

This skill manages Git worktrees for isolated parallel development. It handles creating, listing, switching, and cleaning up worktrees with a simple interactive interface, following KISS principles.
Create a git commit with a clear, value-communicating message. Use when the user says "commit", "commit this", "save my changes", "create a commit", or wants to commit staged or unstaged work. Produces well-structured commit messages that follow repo conventions when they exist, and defaults to conventional commit format otherwise.
This skill should be used when writing Ruby gems following Andrew Kane's proven patterns and philosophy. It applies when creating new Ruby gems, refactoring existing gems, designing gem APIs, or when clean, minimal, production-ready Ruby library code is needed. Triggers on requests like "create a gem", "write a Ruby library", "design a gem API", or mentions of Andrew Kane's style.
