csiddhant796-blipSkillcsiddhant796-blip/claude-skills-collection/karpathy-coder/SKILL.md
Use when writing, reviewing, or committing code to enforce Karpathy's 4 coding principles — surface assumptions before coding, keep it simple, make surgical changes, define verifiable goals. Triggers on "review my diff", "check complexity", "am I overcomplicating this", "karpathy check", "before I commit", or any code quality concern where the LLM might be overcoding.
csiddhant796-blipSkillcsiddhant796-blip/claude-skills-collection/kubernetes-operator/SKILL.md
Use when building a Kubernetes Operator — custom controllers that reconcile CRD state. Triggers on "build an operator", "CRD design", "reconcile loop", "controller-runtime", "kubebuilder", "operator-sdk", "metacontroller", "KOPF", "operator capability levels", or "custom resource". Ships CRD validator, reconcile-loop linter, and OperatorHub capability auditor (all stdlib Python), 4 references on the operator pattern + CRD design + reconcile patterns + tooling landscape, and a /operator-audit slash command. NOT a generic k8s skill — specifically the Operator pattern.
csiddhant796-blipSkillcsiddhant796-blip/claude-skills-collection/llm-cost-optimizer/SKILL.md
Use proactively whenever LLM API costs come up -- or should. Triggers include: 'my AI costs are too high', 'optimize token usage', 'which model should I use', 'LLM spend is out of control', 'implement prompt caching', 'we're about to launch an AI feature', 'build me an AI endpoint'. Don't wait for an explicit cost complaint -- if someone is building an AI feature, designing an LLM endpoint, or choosing between models, cost architecture belongs in the conversation. Apply immediately when any of these are true: a system prompt appears that exceeds a few hundred tokens, all requests are hitting the same model, max_tokens is not set, or no per-feature cost logging exists. NOT for RAG pipeline design (use rag-architect). NOT for improving prompt quality or effectiveness (use senior-prompt-engineer).
csiddhant796-blipSkillcsiddhant796-blip/claude-skills-collection/llm-wiki/SKILL.md
Use when building or maintaining a persistent personal knowledge base (second brain) in Obsidian where an LLM incrementally ingests sources, updates entity/concept pages, maintains cross-references, and keeps a synthesis current. Triggers include "second brain", "Obsidian wiki", "personal knowledge management", "ingest this paper/article/book", "build a research wiki", "compound knowledge", "Memex", or whenever the user wants knowledge to accumulate across sessions instead of being re-derived by RAG on every query.

csiddhant796-blipSkillcsiddhant796-blip/claude-skills-collection/loop/SKILL.md

csiddhant796-blipSkillcsiddhant796-blip/claude-skills-collection/lrs-foreign-investment-tax/SKILL.md
Use this skill whenever an Indian resident asks about investing abroad, LRS remittances, foreign equity taxation, US/Japan/Singapore brokerage accounts, DTAA credits, or related compliance. Triggers include: 'LRS', 'Liberalised Remittance Scheme', 'invest in US stocks from India', 'buy VTI from India', 'foreign brokerage', 'Interactive Brokers India', 'Charles Schwab India', 'TCS on foreign remittance', 'TCS refund', 'Section 206C(1G)', 'DTAA', 'double taxation', 'Form 67', 'foreign tax credit', 'US dividend withholding 25%', 'W-8BEN', 'Schedule FA', 'foreign assets disclosure', 'Section 112 LTCG foreign stock', 'capital gains on US ETF', 'Japan stocks tax India', 'TRC', 'foreign income tax India', 'overseas investment'. ALSO trigger when user mentions ANY non-Indian equity holding or asks about diversifying internationally. Computes: TCS on LRS remittance (20% above ₹10L per FY, refundable via ITR), DTAA dividend withholding lookup for 8 countries, Form 67 foreign tax credit math (FTC = lower of foreign WHT or Indian tax — Rule 128), Section 112 LTCG on foreign stocks (12.5% after 24 months post Budget 2024), Schedule FA compliance reminders.

csiddhant796-blipSkillcsiddhant796-blip/claude-skills-collection/pptx/SKILL.md
Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions \"deck,\" \"slides,\" \"presentation,\" or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
