What it does

Adding Warehouse Person Properties is an agent skill from PostHog/posthog, published by the product's own GitHub organization. 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"…

Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/troubleshooting.md` and `references/where-they-can-be-used.md`).

It sits in Databases, covering Data warehousing and CRM management. It works with PostHog, PostgreSQL, Stripe and Salesforce. The repository describes itself as: :hedgehog: PostHog is the leading platform for building self-driving products. Our developer tools – AI observability, analytics, session replay, flags, experiments, error…

When your agent uses it

  • The user wants to add a person property from my warehouse
  • Enrich people with Stripe/Postgres/Salesforce data
  • Plan tier on my persons
  • Target a feature flag by a warehouse column

Example prompts

  • “add a person property from my warehouse”
  • “enrich people with Stripe/Postgres/Salesforce data”
  • “put ARR or plan tier on my persons”
  • “/adding-warehouse-person-properties”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Find the table
  2. Inspect the columns
  3. Verify the key column before you map anything
  4. Create the definition
  5. Bind the source
  6. Confirm it worked

What it can do on your machine

Read from SKILL.md and the folder at commit 10f9ad7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are sql).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Adding Warehouse Person Properties loads about 2.9k tokens when it runs, and up to ~5.6k if it reads all its reference files. Until then it costs about 177 tokens; SKILL.md has 1,255 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~177
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,255 words (~2,931 tokens).

“A warehouse property mapping reads a synced warehouse table and writes chosen columns onto people or groups. Each row is matched to a person by a distinct ID column, or to a group by a group key column. The mapped…”
