kunanonj Skill

Use when the user asks about revenue, payments, subscriptions, billing, CRM deals, support tickets, production database tables, or other data that PostHog does not collect natively. Also use when a query fails because a table does not exist or returns no results for expected external data.

kunanonj Skill

dingxingdi Bundle

Use this skill when the user wants to prepare, clean, or label datasets for machine learning using specialized code and automated models. Trigger it for requests like 'fill in the missing gaps in my data', 'automatically label this dataset based on our rules', 'impute the null values in my training set', or 'fix the data quality before training'. It is specifically designed for complex ML engineering tasks involving model-based imputation (like recovering sensor readings) and weak supervision pipelines (like heuristic-based labeling) rather than simple SQL data transformations.

Skill: contextual entity disambiguation

dingxingdi Bundle

Use this skill when the user wants SQL data that goes beyond typical READs to encompass data modification loops like INSERT, UPDATE, or DELETE, as well as complex transactional logic for data lifecycles (merging records, setting TTL expirations, or updating locking flags). Trigger it for requests like “make examples that change the database”, “I want the model to delete stale records”, “consolidate these duplicate rows”, or “set an expiration deadline for the specified rows.”

dingxingdi Bundle

Use this skill when an analytics or data transformation task requires combining structured data (CSVs, databases) with unstructured domain logic found in manuals, project handbooks, regulatory guidelines, or business documentation. It is triggered by plain-language requests such as 'calculate our fraud rates using the risk manual', 'harmonize clinical lab data across our medical centers using the conversion guide', 'check if these transactions follow the scheme fee rules', or 'perform a multi-step financial audit'. It is specifically meant for cases where the agent cannot write the code until it first understands complex, implicit rules or industry standard operating procedures (SOPs) buried in text files.

dingxingdi Bundle

Use this skill when the user wants SQL-generation data where the agent must read schema information, consult dialect docs, and produce correct queries for real databases. Trigger it for requests like 'generate enterprise SQL tasks', 'make BigQuery or Snowflake coding questions', 'create SQL problems that need schema lookup and docs', or 'give me text-to-SQL data for code agents'. Do not use it for broader multi-step analytics pipelines with many intermediate artifacts; use the orchestration skill for those.

dingxingdi Bundle

Use this when the user needs a plan that chains together multiple interactive steps where later stages depend purely on earlier outputs, such as passing API parameters, moving text between apps, inserting linked SQL records, or chaining network recon into an executable exploit. Trigger it for requests like 'find information and then process it into a file', 'extract these details and add them to my SQL tables linked by ID', 'forward a code from an SMS to a banking app', or 'scan the server, look up the vulnerability, and execute the payload.'

dingxingdi Bundle

Use this skill when the user wants to autonomously gather datasets from open web sources by writing and executing scrapers or API harvesters. It is triggered by natural language requests such as 'collect all papers from this year's top AI conference', 'give me a CSV of NBA player stats for 2023', 'download daily stock prices for S&P 500 companies', or 'create a dataset of children's book abstracts from the web'. Use this when the agent needs to plan a data acquisition strategy, identify stable web anchors or API endpoints, and generate executable Python scripts to build a curated dataset from scratch.
