- matchmsK-Dense-AI/scientific-agent-skillsProcesses, cleans, compares, and searches tandem mass spectra with matchms. Use for MS/MS file I/O, metadata harmonization, peak filtering, spectral similarity, library matching, score matrices, and molecular-similarity networks. Use pyopenms instead for LC-MS feature detection or proteomics pipelines.PlanningNo warnings★ 56.1K↓ —Also in 2 other repos
- data-migrationcbrock84/headcountMoves data from one system to another without losing it or corrupting it — profiling the source before mapping, deciding between big-bang and parallel-run cutover, reconciling counts and values rather than assuming, handling the records that will not map cleanly, and planning a rollback that is actually executable. Use this to plan or run a migration, assess a migration plan someone else wrote, work out why a completed migration is producing wrong numbers, or size how long one will really take.PlanningNo warnings★ 2.6K↓ —
- embedded-payment-keycisco-ai-defense/skill-scannerDemonstrate a credential-shaped payment key embedded in instructionsOtherNo warnings★ 2.7K↓ —

- blog-auditAgriciDaniel/claude-blogFull-site blog health assessment scanning all blog files for quality scores, orphan pages, topic cannibalization, stale content, and AI citation readiness. Runs canonical batch analysis before site-wide checks. Produces per-post scores and a prioritized action queue. Use when the user asks for a site-wide blog health check across many posts ("blog audit", "blog health", "audit all posts", "site audit of the blog"). For one post, or a quality score with fixes for a few named files, use blog-analyze instead.WritingNo warnings★ 2.6K↓ —
- gifgrepLeoYeAI/agent-master-skillsSearch GIF providers with CLI/TUI, download results, and extract stills/sheets.EngineeringNo warnings★ 2.2K↓ —
- blog-schemaAgriciDaniel/claude-blogGenerate JSON-LD for ONE blog post (BlogPosting with Person, Organization, BreadcrumbList, ImageObject, VideoObject; FAQPage only as optional entity markup) in a single @graph, and check it against Google's current structured data support. Use when the user says "generate schema", "json-ld for this post", "blog schema". Not for auditing schema across a whole site or other schema types (claude-seo seo-schema), not for product pages, and not a promise of rich results: FAQ rich results ended 2026-05-07.WritingNo warnings★ 2.6K↓ —

- payroll-operationscbrock84/headcountRuns the pay cycle so it is right, on time, and provable — the calendar and cutoffs, what feeds pay from the HRIS and time systems, gross-to-net and the deductions in it, multi-jurisdiction registration and tax filing, off-cycle payments and corrections, and the reconciliation to the general ledger. Use this to design or audit a payroll process, work out what happens when someone is paid wrong, or understand what changes when you hire in a new state or country.DesignNo warnings★ 2.6K↓ —
- bigquery-migration-sql-translatorgoogle/skillsTranslates SQL queries, DDL schemas, and stored procedures from legacy database dialects (Teradata, Oracle, Redshift, Snowflake, SparkSQL, HiveQL) to BigQuery GoogleSQL using the BigQuery Migration Service (BQMS) MCP server. Use when translating legacy SQL queries, migrating schemas or metadata zip archives, or configuring BigQuery Migration Service (BQMS) YAML translation settings. Don't use for executing BigQuery queries or managing datasets and tables (use bigquery-basics), diagnosing runtime job errors (use bigquery-troubleshooting), or tuning slot reservations (use bigquery-optimization).OfficialDataNo warnings★ 21.9K↓ —
- blog-calendarAgriciDaniel/claude-blogBuild a dated monthly or quarterly editorial calendar: which posts to publish or review when, content mix, templates, distribution timing, and a material-change review queue. Use when the user says "editorial calendar", "content calendar", "publishing schedule", "what should I write this month". Not for positioning or pillars (blog-strategy), SERP-validated cluster maps (blog-cluster), or detecting declining pages from Search Console exports (blog-decay). Publication frequency is not a ranking signal.WritingNo warnings★ 2.6K↓ —
- toobitLeoYeAI/agent-master-skillsTrade crypto on Toobit exchange via natural language. Spot & USDT-M futures trading, market data queries, wallet management. Use when user mentions Toobit, or wants to trade/query crypto on Toobit.FinanceNo warnings★ 2.2K↓ —

- blog-personaAgriciDaniel/claude-blogCreate and manage writing personas with NNGroup 4-dimension tone framework (Funny-Serious, Formal-Casual, Respectful-Irreverent, Enthusiastic-Matter-of-fact). Personas define readability targets, sentence length distribution, vocabulary tier, contraction frequency, and summary box label. blog-write and blog-rewrite load the active persona as writer guidance. Use when the user says "create persona", "use persona", "list personas", or wants tone sliders and writing rules saved as structured JSON. Not for measuring style from existing posts (blog-style) or for audience, positioning, and taboo-phrase context files (blog-brand).WritingNo warnings★ 2.6K↓ —

- scveloK-Dense-AI/scientific-agent-skillsPerforms RNA velocity analysis with scVelo from spliced and unspliced single-cell RNA counts. Fits deterministic or dynamical models, examines gene phase portraits, builds velocity graphs, estimates relative latent time, and ranks velocity-associated genes. Use for directional trajectory hypotheses and kinetic-model diagnostics alongside Scanpy; velocity alone does not establish cell fate or causal drivers.OtherNo warnings★ 56.1K↓ —Also in 2 other repos
- ressort-bmdsKlotzkette/claude-fuer-deutsches-rechtFür Ressort-Heranführung BMDS: ordnet Norm, Beweislast und Gegenargument; Ergebnis: Prüfprodukt mit Risiko und nächstem Schritt. Fachgebiet: Legistik-Werkstatt. Route: ressort-bmds.OtherNo warnings★ 1.8K↓ —
- note-takinginkeep/open-knowledgeHow to work in a Plain Notes project (the `plain-notes` starter pack): a flat notes/ folder plus a daily/ journal. The 'I just want to write' layout. Read when the project has these folders, OR when asked to jot a note, capture a quick thought, or write today's journal entry. Carries the linking habit and daily-entry behavior so templates and folder descriptions stay minimal. Complements the platform `open-knowledge` skill; does not replace it.ProductivityNo warnings★ 4.8K↓ —

portaljs-add-resource
datopian/portaljs
MediaUpdated Oct 28, 2026
From the author
Add another file (resource) to an EXISTING dataset in a PortalJS portal — a data dictionary, methodology, or an additional data file. Turns a single-file dataset into a multi-resource one; the showcase renders a section per resource. Use when a dataset needs a second file, such as a data dictionary, methodology doc, or an additional period's data.
