gabrielmoreira Skill

Sync columns from a synced data warehouse table onto PostHog person or group properties, so warehouse data becomes usable anywhere person and group properties already work: feature flag targeting, cohorts, insight filters and breakdowns, surveys, session replay filters, workflows, and the person profile. Use when the user wants to "add a person property from my warehouse", "enrich people with Stripe/Postgres/Salesforce data", "put ARR or plan tier on my persons", "target a feature flag by a warehouse column", "sync warehouse columns onto groups or organizations", or wants to inspect, backfill, disable, or debug an existing warehouse-backed person or group property.

forcedotcom Skill

ISV App Analytics metadata types — AppAnalyticsQueryRequest and AppAnalyticsSettings. Use this skill when the user asks about retrieving managed package usage data, configuring App Analytics simulation mode, querying subscriber snapshots, or understanding the AppAnalyticsQueryRequest lifecycle (New → Pending → Complete → Expired). TRIGGER when: user mentions App Analytics, AppAnalyticsQueryRequest, AppAnalyticsSettings, package usage data, subscriber analytics, ISV analytics, or simulation mode for app analytics. DO NOT TRIGGER when: the task is about standard Salesforce reports/dashboards (use reporting skills), custom SOQL on Account/Contact (use platform-soql-query).

iofficeai Skill

Trigger on: 'dashboard', 'KPI dashboard', 'analytics dashboard', 'executive dashboard', 'metrics dashboard', 'CSV to dashboard', 'data visualization'. Output is a single .xlsx. Scene-layer on officecli-xlsx: inherits every xlsx hard rule. DO NOT invoke for: a single budget tracker / one-sheet CSV-with-formatting (use xlsx), a 3-statement / DCF / LBO financial model (use financial-model), a weekly report with ≤ 1 chart and < 10 rows (use xlsx).

kayforkind Bundle

Profiles application, API, and SQL latency from a measured baseline, then applies N+1 joins, indexes, caching, pagination, memoization, and leak cleanup. Use when endpoints, queries, or UI loops are slow and a before/after metric is required. Not for Core Web Vitals page-asset work (LCP, CLS, INP — performance-and-web-vitals). Never a Lighthouse CI budget gate.

kayforkind Skill

Writes Snowflake SQL and pipelines: Dynamic Tables, Streams/Tasks, Snowpipe, Cortex AI/Agents, Snowpark Python, dbt-snowflake, clustering, and RBAC/masking. Use when the user mentions Snowflake, Cortex, Snowpark, Snowpipe, Dynamic Tables, or AI_COMPLETE on Snowflake. Not for BigQuery, Databricks, Redshift, or generic pandas ETL. Never use ACCOUNTADMIN for app roles or omit the colon prefix on SQL procedure variables.

kunagent Skill

Inspect and atomically edit existing DOCX, XLSX, and PPTX files with hash-protected structured operations.

supabase Skill

Use whenever code will build, return, fetch, or execute SQL that runs against a user's real Postgres database — even when the request reads like an ordinary feature or bug fix and never says "security," "injection," or "SafeSqlFragment." This covers: writing or editing any pg-meta function, query builder, or endpoint that builds/returns SQL for database objects (tables, views, functions, DB triggers, indexes, RLS policies); interpolating a schema/table/column/search/route-param value into SQL text; storing, fetching, or re-running SQL that round-trips from the database (a policy's definition, a function/view definition, a snippet's saved content); and any "Run"/"Apply"/"Execute" action that sends SQL to a project's database (SQL editor run-selection, policy editor apply, snippet runner). Load this BEFORE writing such code, not only when reviewing a finished diff. Skip only for changes that never touch SQL text or execution — styling, unrelated data hooks, non-SQL form validation, or UI layout work.

Triggers on terms like "map controls", "crosswalk", "framework alignment", "gap analysis", or producing a STRM CSV output file.

datopian Bundle

Audit a local or remote tabular file (CSV/TSV) for common data quality issues — schema, nulls, types, duplicates. Read-only. Use when a dataset needs a quality check before publishing, or a showcase renders wrong (blank cells, garbled numbers, an unsortable date column) and the cause needs isolating.

Output is a single formula-driven .xlsx. This skill is a scene layer on top of officecli-xlsx — it inherits every xlsx v2 rule (4-color code, visual floor, number formats, cache-drift, Known Issues, Delivery Gate minimum cycle). DO NOT invoke for a simple budget tracker, CSV dump, or operational KPI sheet — route those to officecli-xlsx base.

kayforkind Skill

Chooses and creates Neon Postgres branches (normal vs schema-only) via Neon CLI, MCP, or REST, including reset-from-parent and ephemeral expiry. Use when testing migrations against production-like data or isolating PR/dev databases. Not for picking Neon vs Blob/Redis/Supabase on Vercel (vercel-storage) or writing application SQL.

posthog Bundle

Debugs failing GitHub Actions CI runs for PostHog PRs, commits, and branches, and answers broad CI-health questions ("is CI red?", "is master green today?", "what's broken right now?"). Use when the user asks why CI is red, asks for the current CI or master status, or mentions a failing check, GitHub Actions run, Depot runner, workflow, job, shard, merge queue kick, flaky test, lint failure, typecheck failure, snapshot diff, migration check, generated types drift, or skills build failure. Start with the `hogli ci:insights` digest (cross-run CI history from engineering analytics), then guides read-only inspection, failure classification, smallest local reproduction with hogli, and safe reporting without rerunning CI or posting to GitHub. Running unattended as the "Master-red diagnosis" workflow: see references/master-red-incident.md.

posthog Skill

Gates whether a code comment should exist and forces the ones that stay to explain why, not what. Use ALWAYS before writing or editing a comment in any language (Python, TypeScript, Go, Rust, SQL), and when reviewing a diff that adds comments. Removes the comment types that clutter the codebase: narration that restates the code, change-history and chat-context notes ("previously did X", "per PR #123", "AI:"), perishable measurements and current-state stamps ("~20 min build", "currently", "today"), commented-out code, and redundant docstrings. Keeps the ones that earn their place: a non-obvious why, a warning about a non-local consequence, a pointer to context a future reader can't reconstruct. Not for user-facing copy (see `/writing-user-facing-copy`) or commit messages.

varnan-tech Bundle

Use when the user wants to verify cold emails, enrich a lead list, or autonomously guess email addresses from a CSV using ValidEmail.co or the open-source Reacher engine.

Use when analyzing call paths, mapping attack surface, finding complexity hotspots, enumerating entry points, tracing taint propagation, measuring blast radius, importing SARIF/weAudit/binary findings, linking source graphs across language or RPC boundaries, or building a code graph for audit prioritization. Feature-gate version-specific Trailmark APIs before using them; prefer `trailmark.parse.detect_languages()` or `--language auto` when the target language is unknown or polyglot.
