coalesce-labs/catalyst

Skill Claude CodeCodex

Part of catalyst-dev

Create detailed implementation plans through an interactive process. ALWAYS use when the user says 'plan this', 'create a plan', 'let's plan the implementation', 'design the approach', or wants a structured TDD implementation plan before writing code. Works best after /research-codebase.

Skill Claude CodeCodex

Part of catalyst-dev

Implement approved technical plans from thoughts/shared/plans/. ALWAYS use when the user says 'implement the plan', 'start implementing', 'build from the plan', or wants to execute a previously created implementation plan using TDD (Red-Green-Refactor). Supports team mode for parallel implementation.

Part of catalyst-legacy

End-to-end autonomous workflow — research, plan, implement, validate, ship, and merge in one command. ALWAYS use when the user says 'oneshot', 'do everything end to end', 'full workflow', or wants to go from ticket/idea to merged PR autonomously. All phases run sequentially in the current session, using agent teams…

Skill Claude CodeCodex

Use the Maven Decoder MCP server to inspect code, APIs, methods, dependencies, versions, and usage examples from Maven artifacts installed in the user's local /.m2 repository. Use when working on Java, Maven, Gradle, Spring, Jakarta, Android, or JVM projects and the user asks about dependency internals, installed…

ITlearning/study-ios

Skill Claude CodeCodex

Part of swift-study-skills

Saves learning notes from the current conversation. Classic mode makes concise notes, Mastery mode keeps detailed training artifacts.

ITlearning/study-ios

Skill Claude CodeCodex

Part of swift-study-skills

Adaptive Swift/iOS quiz with two modes. Classic is lighter, Mastery requires mechanism-level reasoning.

ITlearning/study-ios

Skill Claude CodeCodex

Part of swift-study-skills

Interactive Swift/iOS tutor with two modes. Classic explains first, Mastery uses a predict-first Core Loop with gates.

thixpin/pitway

Skill Claude CodeCodex

Method for assessing a codebase's structure — duplication, single-responsibility violations, layering problems, and coupling — and recommending minimal, incremental improvements. Use when asked to review architecture, assess structure or technical debt, evaluate module boundaries, or plan a refactor. Reviews the…

thixpin/pitway

Skill Claude CodeCodex

Checklist and method for reviewing code quality — readability, maintainability, SOLID, DRY, performance, and backward compatibility. Use when asked to review code, a diff, a branch, or a merge request for quality, or before finalizing significant changes. For GitHub PR review use the built-in /review; for…

thixpin/pitway

Skill Claude CodeCodex

Investigate failures whose root cause is still unknown — narrow the search space, instrument, and test falsifiable hypotheses. Use for intermittent or environment-dependent behavior, unexplained stack traces, regressions with no known trigger, or any symptom without a confirmed cause. Ends once the root cause is…

eugenelim/agent-ready-repo

Skill Claude CodeCodex

Use this skill when the user wants to start a new feature with a spec, or wants to write a spec for something they're about to build. Triggers on "new spec", "write a spec for X", "let's spec this out", "start a feature for...". Spec-driven development; the spec drives implementation. Do NOT use for cross-cutting…

eugenelim/agent-ready-repo

Skill Claude CodeCodex

Use when implementing or resuming a non-trivial repository change: a feature, behavior-changing fix, refactor, migration, framework or dependency upgrade, schema or API change, performance work, infrastructure or build-system change, reversion, or an existing build spec under docs/specs/. Also use for bare…

eugenelim/agent-ready-repo

Skill Claude CodeCodex

Use this skill to orient at session start, check initiative queue state, or see what's ready to work on next. Reads workspace.toml and surfaces ready-to-start items, blocked items with reason, parallel candidates, and active signals. Triggers on "workspace status", "where am I", "orient me", "session start", "what's…

chrisallenlane/claude-swe-workflows

Skill Claude CodeCodex

Part of claude-swe-workflows

Proactive bug-hunting workflow. Assesses codebase risk through complexity, coverage, and structural analysis, then spawns focused investigators that write reproducing tests to validate suspected bugs. Thoroughness over speed. Advisory only — produces findings and proposes tickets; does not implement fixes.

chrisallenlane/claude-swe-workflows

Skill Claude CodeCodex

Part of claude-swe-workflows

Autonomous bug-elimination loop. Iteratively invokes /bug-hunt and /implement-batch until findings converge below an operator-specified severity floor. At termination, runs /review-test scoped to the run's new reproducing tests and fixes quality issues above the floor. Auto-approves /bug-hunt and /review-test ticket…

chrisallenlane/claude-swe-workflows

Skill Claude CodeCodex

Part of claude-swe-workflows

Autonomous technical lead. Takes commander's intent and drives a project to completion through an OODA loop over implementation, refactoring, review, and bug-hunting skills. Has broad authority — creates tickets, commits, invokes any skill — and only escalates via andon cord for irreversible actions, public releases…

devPnal/design-system-is-all-you-need

Skill Claude CodeCodex

This skill provides a curated set of cross-platform design guideline prompts for building consistent, high-quality UIs. Each guideline defines common rules, component-specific guides, and an auto-derived token system — all driven by minimal user inputs.

davisjam/model-based-agentic-software-engineering

Skill Claude CodeCodex

Part of mage

Write and diagram engineer-facing prose well — the third partner skill in the govern / operate / communicate trio. It governs the prose the fleet AND its operator produce: the fleet's docs (a control's description, a mechanism entry, a design doc, a runbook, a handoff, a README, a tutorial, an ADR, an API reference)…

davisjam/model-based-agentic-software-engineering

Skill Claude CodeCodex

Part of mage

Apply MAGE to your own engineering work — the capstone mastery-skill of the method. Recognize the engineering situation, decide what to model and what to make authoritative, choose an engineering move, invoke a capability, act through the governed engineering environment, weigh the evidence, and convert durable…

davisjam/model-based-agentic-software-engineering

Skill Claude CodeCodex

Part of mage

Operate an agent-fleet repository as a DevOps engineer — the positive lifecycle map of how the substrate works (managing agents, context windows, the git repo, deploys, the dev machine, cron, and the orchestrator's own hooks), plus a symptom → resolving-doc catalog for when something breaks. Use when running an…

denysdovhan/agents

Skill Claude CodeCodex

Use this skill to maintain an agent log in .agents/log, a decision journal shared by the developer and agents. Trigger when the user explicitly asks to use agent-log or record/update an agent log entry; when planning, implementing, or finalizing a significant feature in a repo with an existing .agents/log; or before…

denysdovhan/agents

Skill Claude CodeCodex

Use when creating, reviewing, debugging, or maintaining Home Assistant custom Lovelace cards or card editors, including custom elements, Web Components, hass data, setConfig, getCardSize/getGridOptions, getConfigElement/getConfigForm, window.customCards, resource registration, HACS card packages, entity display…

MostAshraf/ai-sdlc-harness

Skill Claude CodeCodex

Part of ai-sdlc-harness

Register one new repo into an already-bootstrapped workspace, without disturbing repos already registered or re-running the full interview. USER-ENTRY — invoke only when the user explicitly runs /add-repo; never autonomously, never from a subagent (guard-enforced).
