working-with-nix
Use when working with Nix flakes, selecting devShells, debugging environment issues, or understanding Nix infrastructure - covers shell selection, environment detection, common commands, and project-specific constraints like pinned Rust versions
beautify-decoration
Iterate on the visual identity of a top-down pixel-art decoration (sprite + layout integration) in pixtuoid. Use when redesigning an existing decoration (pantry, lounge, meeting room, cubicle decor) or adding a new one. Captures the rebuild trap, the visual-verification loop, resolution constraints, sprite-format pitfalls, and the layout-integration checklist that we learned the hard way during the pantry beautify session.
codex-implementation-loop
Delegate implementation work to Codex (via the codex-companion runtime), then review its diff, send it back to iterate, gate on the full test suite, and ship it as a PR. Use this whenever the user wants Codex to write code, mentions handing off / delegating implementation to Codex, asks to work through a plan or spec unit-by-unit with Codex doing the coding, or wants a review-and-merge loop wrapped around Codex output â and also when resuming such a loop ("keep going", "next unit", "继ç»ä¸ä¸ä¸ª"). It encodes constraints that are expensive to rediscover: Codex runs in the real environment with effectively read-only git, must not be pointed at a full test suite by default, accepts only specific --effort values, and its self-report is a claim rather than evidence.
/carchitect â Architecture Definition Skill
> **Shared constraints apply.** Before executing, read `_shared/constraints.md` from the parent of this skill's base directory. All constraints there apply to this skill.
Harness Engineering Guide
You are a harness engineering consultant. Your job is to audit, design, and implement the environments, constraints, and feedback loops that make AI coding agents work reliably at production scale.
/ai-llm-safety â AI/LLM Safety Design Enforcement
Every system that involves LLM agents, tool use, or prompt construction MUST treat AI safety as a first-class constraint. Prompt injection is the SQL injection of the AI era â and it's harder to fix after deployment.
add-business-rule
Use this skill when asked to add a validation rule, business rule, or uniqueness constraint to an existing command in a Cratis-based project.
data-validation
Validates data against common and custom rules (required fields, formats, ranges). Use when checking data quality, input validation, or enforcing schemas and constraints.
Roll Brief
> Follows the Architecture Constraints, Development Discipline, and Engineering > Common Sense defined in the project AGENTS.md.
durable-memory
Git-versioned memory stored in the Aikito workspace, separate from any Agent's built-in memory. Use to search, retrieve, or persist cross-project and project-scoped durable knowledge, historical decisions, user preferences, or verified architecture constraints.
code-review-commons
Common guidelines, persona and critical constraints for performing high-quality code reviews. Use this skill when performing a /code-review or /pr-code-review command.
azure-naming-research
Research Azure naming constraints and CAF abbreviations for a given resource type. Use when you need to look up the official CAF slug, naming rules (length, scope, valid characters), and derive validation/cleaning regex patterns for an Azure resource. Triggers on: CAF abbreviation lookup, Azure naming rules research, resource naming constraints.
mex-inbox
Prepare and manage governed MEX Inbox proposals for durable Spec-family knowledge. Use when the user clearly asks to capture, create, save, or draft a MEX product Spec, requirement, constraint, acceptance criterion, or durable product-spec decision for team review, or explicitly invokes /mex-inbox or $mex-inbox. Do not use for email inboxes, generic notes, vague brainstorming, OpenAPI or test specs mentioned only by the word "spec," architecture pages, conventions, patterns, Workstreams, Relays, arbitrary Wiki pages, or generic memory.
agentic-legibility
Score a repository's agentic legibility from repo-visible evidence only. Use when Codex needs to audit how easy a codebase is for coding agents to discover, bootstrap, validate, and navigate, especially for harness-engineering reviews, developer-experience audits, repo cleanup, or before/after comparisons after improving docs, tooling, or architectural constraints.
research-experiment
Coordinate autonomous research experiments across multiple coding agents using isolated git worktrees. Use when a user wants the main agent to define a goal, constraints, acceptance criteria, and experiment boundaries, then dispatch Codex/Claude/Gemini or other agents to independently search for solutions without touching production code.
context-pack
Creates structured handoff briefings between agents. Packages task context, constraints, and progress into a compact packet that subagents can consume without re-reading the full conversation. Prevents the 'lost context' problem in multi-agent delegation.
Textum
Hard constraints: - Low-noise is non-negotiable (avoid attention/context pollution). - Multi-window: each stage is self-contained; do not narrate upstream/downstream flow. - Output ânext stepâ as a stage name only.
atomic-agents
This skill should be used when the user asks to "create a schema", "define input/output", "add fields", "validate data", "Pydantic schema", "BaseIOSchema", or needs guidance on schema design patterns, field definitions, validators, and type constraints for Atomic Agents applications.
Programmatic Agent Constraint Toolkit (PACT): Governance infrastructure for AI coding agents. Claude Code plugin marketplace.
Log a bug investigation using PACT's structured bug tracker
contextual-commit
Write contextual commits that capture intent, decisions, and constraints alongside code changes. Use when committing code, finishing a task, or when the user asks to commit. Extends Conventional Commits with structured action lines in the commit body that preserve WHY code was written, not just WHAT changed.
agent-sop-author
Create (or update) and validate Agent SOPs (Standard Operating Procedures) - markdown-based workflows that guide AI agents through complex, multi-step tasks with RFC 2119 constraints.
wax
Comprehensive guidance for the Wax on-device memory/RAG framework. Use when integrating MemoryOrchestrator, VideoRAGOrchestrator, Wax/WaxSession, embedding providers, hybrid search, maintenance, or when evaluating Wax constraints like offline-only, single-file .wax persistence and deterministic retrieval.
Add constraints from decompiled validation...
s.add(...) if s.check() == sat: m = s.model() print(''.join(chr(m[c].as_long()) for c in flag)) ```
muriel
A multi-constraint solver for visual production â raster, SVG, web, interactive, video, terminal, density viz, gaze, science, infographics, diagrams across eleven output channels plus dimensions + style-guides cross-channel references. Brand tokens, 8:1 contrast rule, and dimension constants stay active at render time. Use when the user needs any visual artifact for human eyes.
framer-component-best-practices
Best practices for building and improving React code components in Framer, a no-code website builder. Covers property controls, animations, accessibility, and platform constraints. Use when creating, editing, or reviewing Framer components, working with ControlType property controls, or building React components for Framer projects.
azure-typespec-author
Author or modify Azure TypeSpec API specifications in the azure-rest-api-specs repository. USE FOR: Any task that creates, modifies, or troubleshoots .tsp files or TypeSpec API specifications â including but not limited to API versioning, ARM or data-plane resource definitions (tracked, proxy, extension, child resources), resource operations (CRUD, PATCH, custom actions, async/LRO), models, enums, unions, properties, decorators, constraints, and swagger-to-TypeSpec conversion. DO NOT USE FOR: SDK generation from TypeSpec, releasing SDK packages, single MCP tool calls that do not require multi-step workflows. TOOLS/COMMANDS: azsdk_typespec_generate_authoring_plan, azsdk_run_typespec_validation
Agent Context File Writer
Writes a high-quality CLAUDE.md, .cursorrules, or .windsurfrules file that gives a coding agent the right project context, conventions, and constraints to work effectively.
