Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00530 |
| Opus 5 | $0.00000 | $0.00265 |
| Sonnet 5 | $0.00000 | $0.00106 |
| Haiku 4.5 | $0.00000 | $0.00053 |
Grade A, and why
posthog 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 8d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PostHog API Skill
Quick Start
PostHog provides complete product analytics. The Node.js SDK allows you to capture events, identify users, and evaluate feature flags from your backend.
npm install posthog-node
Common Workflows
User Identification and Events
When a user signs up, call posthog.identify() to map their internal DB ID to their analytics profile. Then, call posthog.capture() for key backend actions (e.g., 'Subscription Created').
Production Patterns
Feature Flag Evaluation
Evaluate feature flags on the backend before returning UI states. Use posthog.getFeatureFlag(flagKey, distinctId) to gate beta features securely. Local evaluation can dramatically speed up flag checks without hitting the API.
Error Recovery
The posthog-node SDK batches events and flushes them asynchronously. Ensure you call await posthog.shutdown() during your application's graceful shutdown sequence, or you will lose pending events.
Security Notes
Do not log PII (Passwords, SSNs, raw financial data) to PostHog. Scrub payloads before capture. Utilize PostHog's proxy capabilities to bypass ad-blockers securely.
Performance Considerations
Backend feature flag evaluation requires a network round-trip unless you configure Local Evaluation, which periodically syncs flag definitions and evaluates them entirely in-memory.
Testing Guidance
Disable PostHog in unit tests by passing a dummy API key and setting enable: false in the client configuration, or mock the posthog module entirely.
Troubleshooting
If events are missing in the dashboard, verify that you are flushing the queue before the serverless function (e.g., AWS Lambda) terminates. Standard asynchronous event capture will be killed instantly in Lambda.

Why use this skill
Use this when your agent works with posthog — structured patterns beat pasted docs and prevent common hallucinations.
What ships with it
7 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.
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.

posthog is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 530 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
