Skill Claude CodeCodex
Context-driven AI development with AGENTS.md, repo knowledge bases, Claude Code, Codex, and Copilot. Use when adopting repo-native AI workflows or multi-repo setups.
Skill Claude CodeCodex
Builds multi-repo context hubs and compiled markdown knowledge maps. Use when profiling repo portfolios or assembling LLM-ready cross-repo knowledge bases.
Skill Codex
Analyzes commit and PR history to score contribution quality objectively. Use when building engineering scorecards, calibrating promotions, or measuring AI-assist impact.
Skill Codex
Guides dependency management across languages and ecosystems. Use when choosing package managers, lockfiles, update policy, security scanning, SBOMs, or monorepo patterns.
Skill Claude CodeCodex
Generates or validates Conventional Commits messages from staged diffs. Use when drafting commit messages, checking repo rules, or inferring scope from changed files.
Skill Codex needs its repo
Designs team Git workflows for branching, PRs, and releases. Use when choosing branching models, stacked PRs, merge queues, worktree isolation for agents, or collaboration rules.
Skill Codex
Plans complex development workflows for Claude Code, Codex, and assistants. Use when breaking features, refactors, migrations, or parallel work into verified steps.
Skill Codex
Writes PRDs and specs optimized for coding assistants. Use when authoring requirements or project context for Claude Code, Cursor, Copilot, or Codex.
Skill Codex
Writes and reorganizes docs-as-code for software repos. Use when updating READMEs, runbooks, onboarding docs, API references, or agent instruction files.
Skill Codex
Builds local-first note vault retrieval for Obsidian, markdown notebooks, and NotebookLM-adjacent exports. Use when packaging notes into LLM-ready context.
Skill Claude CodeCodex
Create/edit .docx files with styles, templates, comments, and extraction workflows. Use when asked to generate Word reports, contracts, proposals, or convert Word content.
Skill Claude CodeCodex
Extracts, creates, and transforms PDF documents. Use when parsing text or tables, generating files, merging pages, or handling PDF forms.
Skill Claude CodeCodex
Create/edit .pptx presentations with charts, templates, and speaker notes. Use when asked for pitch decks, QBR decks, or slide automation.
Skill Claude CodeCodex
Create/edit .xlsx spreadsheets with tables, formulas, charts, validation, and workbook automation. Use when asked to generate Excel reports, models, exports, or audit spreadsheets.
Skill Codex
Applies planning and search theory (A, CSP, MCTS, STRIPS/PDDL, HTN) to agent design. Use when an LLM agent hallucinates action sequences or needs precondition/effect validity.
Skill Codex
16 behavioral-economics primitives for ethical pricing, choice design, and retention. Use when framing, defaults, habits, dark patterns, AI-agent nudging, or nudge ethics apply.
Skill Codex
Causal-inference primitives: DAGs, IV, RDD, DiD, synthetic control, propensity, CATE, interference. Use when attributing confounded impact or rollout and LLM-eval confounding.
Skill Codex
Consumer-neuroscience primitives for attention, arousal, bonding, narrative, memory, and reward. Use when shaping ethical UX, neuro study design, or DMCC/AI Act gates.
Skill Codex
Control-theory primitives for PID, MPC, Kalman, stability, anti-windup, dead-time, breakers, and limits. Use when tuning autoscaling, retries, or agent loops.
Skill Codex
Applies Beer's VSM and Ashby's Law to diagnose org or agent-system viability. Use when a team or agent hierarchy has coordination, escalation, or requisite-variety problems.
Skill Codex
Decision-theory primitives for uncertain choices, utility, Bayesian decisions, regret, value of information, MCDA, options, and bandits. Use when choosing under uncertainty.
Skill Codex
Distributed-systems primitives for CAP/PACELC, FLP, Paxos, Raft, clocks, CRDTs, leases, quorums, and broadcast protocols. Use when designing coordination.
Skill Codex
Game-theory primitives for strategic decision systems, auctions, mechanism design, incentives, attribution, negotiation, debate, and trust. Use when modeling strategic play.
Skill Codex
Grounding-theory primitives for human-AI and agent handoffs, common ground, acceptance evidence, repair, and ambiguity. Use when coordinating meaning.
