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 | $0.00078 | $0.01041 |
| Opus 5 | $0.00039 | $0.00521 |
| Sonnet 5 | $0.00016 | $0.00208 |
| Haiku 4.5 | $0.00008 | $0.00104 |
Grade A, and why
e2e-self-iteration 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 10d 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.

E2E Self-Iteration Skill
Combines ProofShot (visual proof recording) and agent-browser (headless browser control) with the self-improvement loop for automated E2E testing, visual regression detection, and iterative bug fixing.
Quick Reference
| Situation | Action |
|---|---|
| Need to verify UI changes | vx just e2e-proofshot |
| Found visual regression | Log to .learnings/ERRORS.md, fix, re-run |
| Self-iteration loop | vx just e2e-iterate |
| PR needs proof | vx just e2e-pr |
| Explore UI elements | vx just e2e-snapshot |
| Compare against baseline | vx just e2e-diff |
Prerequisites
# Install ProofShot + agent-browser
vx just e2e-install
Workflows
1. Quick Visual Verification
After making UI changes, verify them visually:
vx just e2e-start # Build + start Gallery with CDP
vx just e2e-snapshot # See interactive elements
vx just e2e-screenshot # Capture annotated screenshot
vx just e2e-stop # Cleanup
2. Full ProofShot Session
Record a complete verification session with video + artifacts:
vx just e2e-proofshot # Full automated flow
This will:
- Pack Gallery (debug mode)
- Start with CDP enabled
- Record ProofShot session
- Capture snapshots and screenshots
- Run Playwright CDP tests
- Stop and generate artifacts
3. Self-Iteration Loop
When fixing bugs or implementing features, iterate:
# Cycle: build → start → verify → fix → repeat
vx just e2e-iterate
# Review artifacts after each iteration
ls proofshot-artifacts/
4. agent-browser Primitives
Direct browser control commands:
# Element discovery
vx just e2e-snapshot
# Navigation
vx just e2e-open "http://localhost:5173/settings"
# Interaction
vx just e2e-click "@e5"
vx just e2e-fill "@e2" "test value"
# Screenshot
vx just e2e-screenshot
5. Visual Regression Testing
Compare current state against baseline:
vx just e2e-diff
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.

e2e-self-iteration is a skill published in the GitHub repository loonghao/auroraview (44 stars, last pushed 1mo ago), licensed MIT. It adds 78 tokens to every session and 1,041 once invoked, about $0.0004 per session on Opus 5. 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 2026-08-30.
