Coding & Dev Tools
Coding agent skills teach AI agents repeatable engineering workflows: reviewing pull requests, writing tests, refactoring safely, and enforcing house style. Install one SKILL.md and your agent applies the same checklist every time, whether you use Claude Code, Cursor, Codex, or another agent.

pawpair Skill Paw Mail UsageHow to use the Paw Mail CLI (paw-mail). Use this skill when: (1) you need to run a CLI command (auth, accounts, emails, sync, threads, config), (2) someone asks how to use or invoke the mail CLI, (3) you need to check CLI flags or subcommands.

performancecopilot Skill Macos QA TestRun darwin PMDA QA tests in isolated Cirrus VM environment
-
perhapsspy Bundle Chatgpt Pro ReasonerUse only when the user explicitly invokes $chatgpt-pro-reasoner to send a focused thinking problem to ChatGPT Pro through the Codex in-app browser. Treat ChatGPT Pro as an external reasoning head, and keep consultations in one dedicated Codex Reasoner ChatGPT project that the skill initializes on first use.
-
perhapsspy Bundle Codex Token DisciplineUse for Codex work with clear excess-cost risk: broad or unpredictable logs and diffs, browser/UI loops, costly execution/retry loops and progress observation even with small output, subagents, repeated compaction, or explicit usage audits. Guides bounded execution and observation, preflight output limits, bounded delegation, evidence reuse, and compact checkpoints. Skip routine edits and direct answers. Routine test runs alone are not a trigger.
-
perhapsspy Bundle Justified ChangeUse for non-trivial code-change planning, implementation, bug fixes, refactors, review edits, and diff reviews where scope decisions such as fields, options, abstractions, or follow-ups must be necessary, goal-proportional, evidence-backed, and verifiable without speculative work
-
pgrundev Skill Postgres DiagnosticsDiagnose PostgreSQL health and performance using the read-only pgbot tool. Use for slow databases, expensive queries, unused indexes, disk usage, bloat, autovacuum, vacuum health, and configuration questions.
-
pedrovelasquez9 Skill OnbeardingUse when landing in an unfamiliar codebase and you need the guided tour - the bearded senior's four-phase onboarding that maps infrastructure and data flow, the layered architecture, the flow of one real operation file-by-file, and then audits every claim to separate what was read from the code versus what was inferred. Trigger on "onboard me", "onbearding", "give me the tour", "help me understand this project", "walk me through this codebase", "ponme al día con este proyecto", "explícame este código", "hazme el onboarding".
-
perhapsspy Bundle Structure FirstUse for code generation, feature work, bug fixes, refactoring, and code review when a change creates or reshapes a multi-step flow, state lifecycle, side-effect or decision ownership, cross-unit composition, or boundary contract. Also use it when an existing structural problem makes those elements hard to trace or verify. Structural change is optional. Mechanical edits, throwaway experiments, and coherent local changes stay with their current owner and focused verification.
-
phaddad90 Bundle TrainRun a batch of work as a merge train - N streams building concurrently in isolated worktrees, each self-verifying to green, integrated once and shipped once. Use for ANY multi-item batch of work in ANY repo, in place of building serially in the shared tree. Modes - "init" to onboard or retrain a repo (measures its substrate first), "retro" to fold a finished train's lessons back into the method. Triggers - "run a train", "train init", "train retro", "parallel streams", "batch this work".
-
phatnguyen975 Bundle Scenario Test DesignApply this skill whenever a user needs to design test scenarios based on real-world business workflows before writing test data or test scripts. Triggers on: "design test scenarios", "scenario testing", "create test scenarios", "scenario-based testing", "test scenario design", "identify test scenarios", "write test cases from requirements", or any request to analyze requirements, BRs, FRs, or User Stories and produce scenario flows. This skill covers TEST DESIGN (analysis + scenario flow), NOT automation code or test scripts. Invoke even if the user only pastes requirements and says "help me test this".
-
pehcastro Bundle CorpusWorked examples of bad and corrected Claude Code chat output. Use when a reply is about to run long, when unsure whether a sentence is decoration or information, when a status update is forming, or when the user says the output is too long, too corporate, full of jargon, or reads like AI. Also use when writing or editing the Brevity output style itself.
-
peiiii Bundle Project OsAI project OS for autonomous loop, automated orchestration, and rule-driven execution.

pem725 Bundle AI Rosetta StoneTranslates Claude concepts and terminology to ChatGPT, Gemini, and Microsoft Copilot (consumer, Microsoft 365, and GitHub variants) equivalents.
