Cold Load Trim
Reduce first-load bytes without breaking the first impression.
Use when
A web app ships too much before showing anything useful.
Cadence
When first visit feels heavy
Verification
Initial screen downloads fewer bytes while screenshots and behavior remain unchanged.

| Field | Value |
|---|---|
| Name | Cold Load Trim |
| Category | Engineering |
| Trigger | When first visit feels heavy |
| Objective | Reduce first-load bytes without breaking the first impression. |
| Allowed inputs | Relevant files, source notes, logs, tests, screenshots, metrics, or task state for this loop |
| Allowed actions | Define the exact scope, source of truth, and approval boundary.; Inspect current state and rank the highest-risk gap.; Make one small, reversible improvement.; Run the stated verification and record evidence.; Stop on success, budget, no progress, or approval required. |
| Verification | Initial screen downloads fewer bytes while screenshots and behavior remain unchanged. |
| Stop condition | Stop when the verifier passes, the budget is exhausted, no progress is made, a blocker appears, or approval is required. |
| Budget | Set a time, turn, token, retry, file, or dollar cap before running the loop. |
| Approval boundary | Human approval required before publishing, sending, deleting, spending, changing accounts, touching production, or making reputational/legal/financial commitments. |
| Safe output | Pull request, patch, report, or evidence log |
| Works with | Claude Code, OpenAI Codex, Cursor, Gemini CLI, any tool-using coding agent |

- Define the exact scope, source of truth, and approval boundary.
- Inspect current state and rank the highest-risk gap.
- Make one small, reversible improvement.
- Run the stated verification and record evidence.
- Stop on success, budget, no progress, or approval required.

Run the Cold Load Trim loop. Use it when A web app ships too much before showing anything useful. Work in bounded iterations: inspect current state, choose the highest-risk gap, make one reversible improvement, verify it, and record evidence. Stop when Initial screen downloads fewer bytes while screenshots and behavior remain unchanged. or when blocked, budget exhausted, or approval is required.
