Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
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/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".
AnthropicSkillanthropics/claude-plugins-community/tres-finance-plugin/skills/tres-cost-basis/SKILL.md
Manage cost basis calculation in TRES Finance: check status, view/change strategy (FIFO, LIFO, AVG, MAX_GAINS, MAX_LOSSES, FIFO_IMPAIRMENT), trigger recalculation, review financial issues, manage reevaluations/impairments, set bulk fiat prices, configure spec-ID lot disposal rules, view per-asset cost basis results, and export cost basis reports. Trigger this skill whenever the user asks about cost basis, gains/losses, realized gains, unrealized gains, COGS, inventory lots, tax lots, cost basis strategy, reevaluation, impairment, fiat value override, spec-ID rules, financial issues (negative balance, missing fiat), or anything related to how their crypto assets are costed. Also trigger when the user says "calculate cost basis", "what is my cost basis strategy", "show me financial issues", "create a reevaluation", "run cost basis", "change strategy to LIFO", or similar.
AnthropicSkillanthropics/claude-plugins-community/tres-finance-plugin/skills/tres-data-collection-commit/SKILL.md
Trigger on-chain data collection (a "Commit") in Tres Finance for wallets that have already been onboarded. Use this skill whenever the user wants to collect data, pull balances, sync wallets, refresh on-chain data, run a commit, trigger a commit, or "collect" anything in Tres. This is the second step of the Tres onboarding flow — it sits between wallet upload (tres-wallets-upload) and balance validation (tres-asset-balance-validation). Always trigger this skill for any request that mentions "commit", "collect", "data collection", "pull data", "fetch on-chain data", "sync wallets", "refresh balances", or anytime the user just finished uploading wallets and is ready to bring in their on-chain data.
AnthropicSkillanthropics/claude-plugins-community/tres-finance-plugin/skills/tres-erp-rule-suggestions/SKILL.md
Guide users through creating ERP accounting rules for crypto organizations on the Tres Finance platform. Maps every transaction type to the correct chart of accounts entries using a layered rule engine. Trigger: user asks to create, review, or fix ERP rules / accounting mappings for an organization.
AnthropicSkillanthropics/claude-plugins-community/tres-finance-plugin/skills/tres-explorer-tx-to-ledger/SKILL.md
Add a blockchain explorer transaction to the TRES Finance ledger. Use when the user provides a blockchain explorer URL (Etherscan, Polygonscan, Arbiscan, Basescan, Snowtrace, BscScan, etc.) or a raw transaction hash and wants to record it in the platform ledger. Trigger phrases include "add this transaction", "import tx from etherscan", "record this on-chain tx", "add to ledger".
AnthropicSkillanthropics/claude-plugins-community/tres-finance-plugin/skills/tres-export-3rd-party-contacts/SKILL.md
Extract all 3rd-party (non-owned) addresses from a TRES Finance environment and export them as an XLSX workbook to help users build their contacts list. Use this skill whenever the user wants to export, list, or identify 3rd-party addresses, counterparties, or external addresses from their transactions — even if they don't say 'contacts'. Also trigger when the user asks to prepare a contacts import file, find unknown addresses, or build an address book from transaction history. Do NOT trigger for viewing existing contacts or searching the address book — only for extracting NEW 3rd-party addresses from transaction data.
AnthropicSkillanthropics/claude-plugins-community/tres-finance-plugin/skills/tres-import-contacts/SKILL.md
Import contacts (address book entries) into TRES Finance from a CSV or XLSX file. Use this skill whenever the user wants to import, upload, or bulk-add contacts, address labels, or address book entries into TRES — whether from a file they filled in after using the export-3rd-party-contacts skill, or from any CSV/XLSX that maps addresses to names. Trigger phrases include: 'import contacts', 'upload contacts', 'add contacts from file', 'import address book', 'load contacts into TRES', 'bulk label addresses', 'import the contacts file', 'upload the filled contacts sheet'. Also trigger when the user says something like 'I filled in the contacts file, now import it' or 'here is my contacts spreadsheet, please upload it to TRES'. Do NOT trigger for exporting or extracting unidentified addresses — that's the export-3rd-party-contacts skill. Do NOT trigger for viewing or searching the existing address book.
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.
