session-replay

session-replay is a skill for Claude Code from nexus-labs-automation/mobile-observability. It costs 26 tokens per session (332 once invoked), scanned A, original, MIT.

A session-replay setup guide for recording visual copies of user sessions so developers can inspect what happened on screen.

In plain words
What is it for?
Use it when adding screen recordings, replay features, or visual debugging. It covers error-session recording, selected user journeys, sampling, privacy masking, and setup with monitoring services.
Why use it?
It helps reproduce difficult bugs and investigate user confusion without relying only on written reports. It also explains how to hide private information and limit recording's effect on device performance.

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

session-replay 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 12d 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.

What it actually says

Session Replay

Capture visual recordings of user sessions for debugging.

When to Use

  • Reproducing hard-to-debug issues
  • Understanding user confusion
  • QA and support investigations

Privacy Requirements (Must Do)

Mask by default:

  • All text input fields
  • Passwords and sensitive data
  • User-generated content
  • Financial information
  • User photos/documents

Performance Budget

Resource Limit
CPU <5% additional
Memory <20MB additional
Network Batch on WiFi
Battery Pause when low

Capture Strategies

Strategy Fidelity Overhead
Screenshots (1-2 fps) Lower Lower
View hierarchy recording Higher Moderate
Hybrid (screenshots + events) Best Moderate

Best Practice

Don't record everything. Target:

  • Error sessions only (rolling buffer)
  • Key user journeys
  • 1-10% sampling for general insights

Implementation

See references/session-replay.md for:

  • Platform-specific setup
  • Privacy masking patterns
  • Vendor configurations (Sentry, Datadog, New Relic)
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.
