# Web Agent Observability

Observability pack for browser agents: structured action logs, traces, screenshots, latency/cost metrics, and failure taxonomy for RSEO improvement loops.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Browser |
| Unlock | $5.99 USDC (x402 Base) |
| Triggers | web agent observability, browser agent traces, debug browser agent, /web-agent-observability |

## When to use
- Browser agents flake
- Need run evidence
- Cost/latency of web agents

## Core workflow
1. Instrument runner
2. Emit spans
3. On fail attach artifacts
4. Classify failure
5. Feed RSEO

## Procedures (non-obvious)
Redact secrets and PII from screenshots/logs before storage.
Spans: navigate, act, wait, extract, assert, handoff.
Failure classes: selector_miss, timeout, auth, challenge, allowlist, application_error.

## Edge cases
- Huge traces sample on fail only
- Video optional with retention limits

## Failure modes
- Logging secrets
- No correlation ids across steps

## Verification
- Failed run produces taxonomy + artifacts
- Secrets redacted

## Artifact outputs
- `actions.jsonl`
- `observability-report.md`
- `trace.zip`

## Super Alignment Contract
- Scalable oversight method: process supervision + human+AI critique before high-blast actions
- Corrigibility guarantees: shutdown, steerability, non-deception; operator may abort mid-run
- Value model: Partnership Agreement + 5 Behavioral Protocols
- Drift detection: flag invented evidence, skipped verification, or revenue-over-truth optimization
- Red-team surface: prompt injection via retrieved conte
