What it does
Session Replay is an agent skill from nexus-labs-automation/mobile-observability. Set up session replay for visual debugging. Use when implementing screen recording, replay features, or visual debugging tools.
Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Debugging. The repository describes itself as: Claude Code plugin for mobile app observability: crash reporting, performance monitoring, and instrumentation for iOS, Android, and React Native. The licence is MIT.
When your agent uses it
- Implementing screen recording
- Replay features
- Visual debugging tools
Example prompts
- “/session-replay”
What it can do on your machine
Read from SKILL.md and the folder at commit 488c97f. 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.
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
Session Replay loads about 362 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 116 words of instructions outside code blocks.
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

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)
