survey-sdk-audit

survey-sdk-audit is a skill for Claude Code from PostHog/posthog-foss. It costs 30 tokens per session (4,182 once invoked), scanned A, original, MIT.

A checklist for checking which features and minimum versions are supported by PostHog survey SDKs. An SDK is the library an app uses to add PostHog features on a specific platform.

In plain words
What is it for?
Use it to audit a survey feature across the JavaScript, iOS, Android, and Flutter SDKs and update the feature version requirements.
Why use it?
It prevents documentation or implementation decisions based on unsupported SDK versions. It also identifies when the required source repositories are unavailable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

survey-sdk-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/repos.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Surveys SDK Feature Audit Skill

Use this skill when auditing survey feature support across PostHog SDKs for surveyVersionRequirements.ts.

Feature to audit: $ARGUMENTS

For survey feature work, read Contributing survey changes. For customer diagnosis without a repository checkout, use the published debugging-surveys skill.

Setup Check (Run First)

Before starting, verify the SDK paths are accessible. Run ls on each path:

  • $POSTHOG_JS_PATH
  • $POSTHOG_IOS_PATH
  • $POSTHOG_ANDROID_PATH
  • $POSTHOG_FLUTTER_PATH

If any path is empty or doesn't exist, ask the user: "I need the path to [SDK repo] on your machine. Where is it located?"

Once you have all paths, ask the user if they'd like to save them for future sessions by adding to .claude/settings.local.json:

{
  "env": {
    "POSTHOG_JS_PATH": "/path/to/posthog-js",
    "POSTHOG_IOS_PATH": "/path/to/posthog-ios",
    "POSTHOG_ANDROID_PATH": "/path/to/posthog-android",
    "POSTHOG_FLUTTER_PATH": "/path/to/posthog-flutter"
  },
  "permissions": {
    "allow": [
      "Read(/path/to/posthog-js/**)",
      "Read(/path/to/posthog-ios/**)",
      "Read(/path/to/posthog-android/**)",
      "Read(/path/to/posthog-flutter/**)",
      "Grep(/path/to/posthog-js/**)",
      "Grep(/path/to/posthog-ios/**)",
      "Grep(/path/to/posthog-android/**)",
      "Grep(/path/to/posthog-flutter/**)"
    ]
  }
}

Note: The Read and Grep permissions grant Claude access to these external SDK repositories without prompting each time.

Using SDK Paths in Commands

IMPORTANT: Environment variables like $POSTHOG_JS_PATH do NOT expand reliably in Bash tool commands.

Instead of bash commands, prefer:

  • Use the Read tool to read files (works with permissions)
  • Use the Grep tool to search files (works with permissions)

If you must use bash, first expand the variable:

echo $POSTHOG_JS_PATH

Then use the echoed path directly in subsequent commands.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
