What it does

Creating Replay Vision Scanners is an agent skill from PostHog/posthog, published by the product's own GitHub organization. Guides agents through creating and safely sizing a Replay Vision scanner: choosing the scanner type (monitor/classifier/scorer/summarizer), shaping the RecordingsQuery that selects sessions, and — crucially — estimating the credits it will spend and checking the org's remaining budget before creating, so a broad scanner doesn't exhaust the budget on its first scheduled sweep. TRIGGER when: user asks to create, set up, or configure a Replay Vision scanner, OR when you are about to call vision-scanners-create, OR…

Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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

  • : user asks to create
  • Configure a Replay Vision scanner
  • When you are about to call vision-scanners-create
  • When widening an existing scanners query

Example prompts

  • “s remaining budget before creating, so a broad scanner doesn”
  • “Use the creating-replay-vision-scanners skill to guide agents through creating and safely sizing a Replay Vision scanner: choosing the scanner type…”
  • “/creating-replay-vision-scanners”

Workflow steps

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

  1. What should the scanner do?
  2. Which sessions?
  3. Size it — the gut-check (do not skip)
  4. Create

What it can do on your machine

Read from SKILL.md and the folder at commit c012c8d. 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 json).

    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

Creating Replay Vision Scanners loads about 3.6k tokens when it runs. Until then it costs about 261 tokens; SKILL.md has 1,686 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~261
When it runs · the whole SKILL.md, loaded when a task matches
~3.6k

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 1,686 words (~3,569 tokens).

“A scanner is a standing LLM probe over session recordings. Once created and enabled, it runs on a Temporal schedule that sweeps every 5 minutes, applying its prompt to each new matching recording and recording the result as an observation…”
