Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
AnthropicSkillanthropics/claude-agent-sdk-python/.claude/skills/verify/SKILL.md
Drive this repo's build/release scripts end-to-end without touching the network. Use when verifying changes to scripts/download_cli.py, scripts/build_wheel.py, scripts/update_cli_version.py, or scripts/_cli_version_validation.py.
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/customize/SKILL.md
Adapt this C/C++ ASAN vulnerability pipeline to a different vulnerability class, target shape, language, or detection mechanism. Use when the user wants to port, migrate, retarget, customize, or fork the pipeline for something other than C/C++ memory-safety bugs — web apps, smart contracts, deserialization, ML systems, or any other domain.
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/dnr-hunt/SKILL.md
Proactive threat hunt over web/application logs — no alert in
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/dnr-respond/SKILL.md
Incident response workup for a lead in hand — an alert, an IOC,
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/patch/SKILL.md
Generate candidate fixes for verified security findings. Consumes
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/quickstart/SKILL.md
The front door for this repo. With no argument: a 30-second intro, then an offer to walk you through your first run on the canary target. With a question: answers it from this repo's own docs and source, cites where it looked, and hands you the next command. Use for "how do I…", "why does…", "where is…", "can this…", or just "/quickstart" to get oriented.
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/threat-model/SKILL.md
Build a threat model for a target codebase. Three modes: "interview" walks an application owner through the four-question framework and produces a threat model from their answers; "bootstrap" derives a threat model from the code plus past vulnerabilities (CVEs, git history, pentest reports) when no owner is available; "bootstrap-then-interview" chains the two when both owner and codebase are present. All write THREAT_MODEL.md in a shared schema. Use when asked to "threat model", "build a threat model", "map the attack surface", or "what should we be worried about in this codebase".
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/triage/SKILL.md
Triage a batch of raw security findings. Verify each is real,
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/verify/SKILL.md
Verify harness changes end-to-end without docker — drive the real pinned CLI against a header-capturing stub server with the exact env resolve_auth_env() produces.
AnthropicSkillanthropics/defending-code-reference-harness/.claude/skills/vuln-scan/SKILL.md
Static source-code vulnerability scan. Reads a target directory (and THREAT_MODEL.md if present), spawns parallel review subagents per focus area, and writes VULN-FINDINGS.json + .md for /triage to consume. Read-only — no building, running, or network. For execution-verified crashes, use vuln-pipeline instead. Use when asked to "scan for vulns", "review this code for security issues", "find bugs in <dir>", or as the step between /threat-model and /triage.
AnthropicSkillanthropics/claude-plugins-community/eli5/skills/eli5/SKILL.md
Explain a topic like I'm a 5 year old. Use when the user types /eli5 <topic> or asks for a dead-simple picture explainer of how something works.
AnthropicSkillanthropics/claude-plugins-community/quickdesign/skills/quickdesign/SKILL.md
Use the `quickdesign` CLI to generate AI media — UGC promo videos, image edits, product creatives, video upscales — through Seedance, Kling, Sora2, Nano Banana, and GPT Image. Invoke this skill whenever the user asks for a talking-avatar video, multi-segment ad / promo / explainer, image edit (object swap, angle change, state change), product photoshoot, or video upscale via QuickDesign.
AnthropicSkillanthropics/claude-plugins-community/testdino/skills/testdino-audit/SKILL.md
Use only when the user explicitly asks for a TestDino audit of Playwright automated test code. Routes through the audit tools the TestDino MCP server exposes (get_audit_report + submit_audit_report, or the legacy test_audit). For generic code review or non-Playwright targets, do a normal review instead.
AnthropicSkillanthropics/claude-plugins-community/testdino/skills/testdino-health/SKILL.md
Use when the user wants to check TestDino connection status, validate their PAT, discover available organizations and projects, or find the right projectId. Always call this first when the project context is ambiguous before any other TestDino tool.
AnthropicSkillanthropics/claude-plugins-community/testdino/skills/testdino-manual-runs/SKILL.md
Use when the user wants to manage a manual execution run or update case-level results inside a run — listing runs, creating runs for a release, inspecting a run, assigning cases, or marking case results (passed/failed/blocked/skipped/retest/untested). Accepts counter-style IDs like RUN-12 and TC-156.
AnthropicSkillanthropics/claude-plugins-community/testdino/skills/testdino-manual-tests/SKILL.md
Use when the user wants to create, update, or browse manual QA test cases and suites in TestDino — not execution runs. Covers list_manual_test_suites, list_manual_test_cases, get_manual_test_case, create_manual_test_case, update_manual_test_case, create_manual_test_suite.
AnthropicSkillanthropics/claude-plugins-community/testdino/skills/testdino-releases/SKILL.md
Use when the user wants to browse, inspect, create, or update releases/milestones in a TestDino project. Covers list_releases, get_release, create_release, and update_release. Accepts counter-style IDs like MS-12.
AnthropicSkillanthropics/claude-plugins-community/testdino/skills/testdino-runs/SKILL.md
Use when the user wants to inspect automated test runs, list failed or flaky tests, debug a failing testcase with historical context, or filter runs by branch, commit, author, environment, browser, status, or tags. Includes list_testruns, get_run_details, list_testcase, get_testcase_details, and debug_testcase.
AnthropicSkillanthropics/claude-plugins-community/testdino/skills/testdino-sessions/SKILL.md
Use when the user wants to browse, inspect, create, or update exploratory testing sessions in TestDino — by state, status, session type, assignee, release, or tags. Covers list_sessions, get_session, create_session, and update_session. Accepts counter-style IDs like SES-12.
AnthropicSkillanthropics/claude-plugins-community/tres-finance-plugin/skills/tres-asc845-swap-reprice-skill/SKILL.md
Reprice swap transaction legs under ASC 845 (Nonmonetary Transactions) to ensure clearing accounts net to zero. Use this skill whenever the user wants to: reprice swaps, fix clearing account residuals, apply equal-value exchange to swap legs, run setBatchUseCounterpartyFiatValue, zero out a clearing account, apply ASC 845, fix swap pricing mismatches, ensure no gain/loss on swaps, or close a month where a swaps/trade clearing account has a residual balance. Also trigger when the user mentions "counterparty fiat value", "swap repricing", "clearing account net to zero", or "equal value exchange".
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
