Product-thinking skills. Write staff-level PRDs and slice them into testable user stories. Standalone, but their output (in .plan/<feature>/) can feed the eng pipeline's /scope.
Write a real Product Requirements Document at the bar a senior/staff engineer or PM would ship at a top org (Google, Meta, Amazon, Apple). Gathers context, grills the user on the gaps, then produces a rigorous PRD: crisp problem statement, measurable goals & explicit non-goals, success metrics with baseline→target, prioritized requirements (P0/P1/P2), user journeys, risks, dependencies, and a phased rollout. Standalone — its output can feed /scope but it is NOT in the eng doc schema. Use when the user wants a PRD, product spec, one-pager, or PR/FAQ. Triggers: "write a PRD", "product spec", "product requirements", "spec this out", "one-pager", "PR/FAQ".
Break a PRD, epic, or feature idea into well-formed user stories — "As a <persona>, I want <goal>, so that <benefit>" — each with clear, testable acceptance criteria (Gherkin given/when/then). Uses real personas when a personas skill is available, sizes stories to be independently shippable, and orders them. Output feeds /scope. Use when the user has a PRD/epic to slice or asks for user stories. Triggers: "user stories", "break into stories", "write stories for this", "slice this epic", "story map".
Personal Claude Code plugins — reusable skill packs for engineering workflows, packaged as a Claude Code plugin marketplace so they work in any project.
eng — plan-to-ship engineering pipelineFive composable skills plus an orchestrator. Each skill is a single pass over a
shared markdown doc that lives in the target project's .plan/ folder, so they
work solo or chained. The doc holds all state; the skills communicate through it.
| Skill | What it does |
|---|---|
/scope | Explore the codebase, decide ticket breakdown (asks you), draft a planning doc per ticket with real file:line touchpoints, house conventions, and open questions. Drafts Jira ticket text (output only). |
/grill | Read the doc's open questions, grill you (eng + business), explore for context, write answers into Decisions and sharpen acceptance criteria. |
/eng-review | EM-style review: architecture, edge cases, tests, performance, and consistency with how this codebase already builds things. Folds fixes back in. |
/tdd | Turn acceptance criteria into a test contract: unit-test spec + manual/UI QA checklist. Specifies tests; doesn't write them. |
/execute | Write the specified tests (failing first), implement against the plan & house conventions, make tests pass, verify acceptance criteria, run QA, update the doc. |
/eng-flow | Orchestrator — runs scope → grill → eng-review → tdd → execute off the doc's phase, pausing at a gate between each. Resumes wherever you left off. |
The doc schema every skill obeys is the keystone: see eng/SPEC.md.
<project>/.plan/<feature-slug>/
README.md # feature index + per-ticket status
<NN>-<ticket-slug>/doc.md # one self-contained doc per ticket
.plan/ is committed so the plan lives in history (plan-said-X vs reality-was-Y).
product — product-thinking skillsStandalone from eng, but their output (written to .plan/<feature>/) can feed
/scope.
| Skill | What it does |
|---|---|
/prd | Write a staff-level PRD (Google/Meta/Amazon bar): problem, measurable goals & non-goals, success metrics, prioritized requirements, risks, rollout. Supports the Amazon PR/FAQ format. NOT in the eng doc schema. |
/user-stories | Slice a PRD/epic into INVEST user stories with Gherkin acceptance criteria, ordered with dependencies. Feeds /scope. |
productivity — workflow helpers| Skill | What it does |
|---|---|
/catchup | Summarize what changed (branch / PR / commit range / file) so you can resume or review fast. |
/caveman | Ultra-terse communication mode — ~75% fewer tokens, full technical accuracy. Persists until "normal mode". |
/handoff | Compact the conversation into a handoff doc (saved to the OS temp dir) for a fresh agent to continue. |
/grill-me | Standalone relentless interview on any plan/design (not tied to .plan docs — use eng's /grill for those). |
Add this repo as a marketplace, then install the plugins you want:
/plugin marketplace add nitintf/ai-skills
/plugin install eng@nitin-ai-skills
/plugin install product@nitin-ai-skills
/plugin install productivity@nitin-ai-skills
(Or /plugin marketplace add <path-to-local-clone> while developing.)
Skills are plain markdown at eng/skills/<name>/SKILL.md. Edit and reload. When
adding a field or section, update eng/SPEC.md first — it's the contract all
the skills depend on.

npx claudepluginhub nitintf/ai-skills --plugin productPlan-to-ship engineering pipeline. Five composable skills (scope, grill, eng-review, tdd, execute) plus an orchestrator (eng-flow). Each is a single pass over a shared markdown doc in the project's .plan folder, so they work solo or chained.
General workflow helpers: catch up on what changed, compress communication (caveman), hand off a session to a fresh agent, and get grilled on any plan or design.
Comprehensive skill pack with 66 specialized skills for full-stack developers: 12 language experts (Python, TypeScript, Go, Rust, C++, Swift, Kotlin, C#, PHP, Java, SQL, JavaScript), 10 backend frameworks, 6 frontend/mobile, plus infrastructure, DevOps, security, and testing. Features progressive disclosure architecture for 50% faster loading.
Tools to maintain and improve CLAUDE.md files - audit quality, capture session learnings, and keep project memory current.
Develop, test, build, and deploy Godot 4.x games with Claude Code. Includes GdUnit4 testing, web/desktop exports, CI/CD pipelines, and deployment to Vercel/GitHub Pages/itch.io.
A growing collection of Claude-compatible academic workflow bundles. Covers scientific figures, manuscript writing and polishing, reviewer assessment, citation retrieval, data availability, paper reading, literature search, response letters, paper-to-PPTX conversion, and evidence-grounded Chinese invention patent drafting. Rules are organized as reusable skill folders with explicit workflows and quality checks.
Create new skills, improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, or benchmark skill performance with variance analysis.
