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.
Structured loop spec
| 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 |
Steps
- 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.
Prompt
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.Run in Claude Code
Paste this into Claude Code (or any tool-using agent) to run the loop bounded: one change per round, the same verification every round, durable state files, and explicit stop conditions.
Run the "Cold Load Trim" loop from AI Loop Library (https://ailooplibrary.com/loops/cold-load-trim/) as a bounded loop.
Goal: Reduce first-load bytes without breaking the first impression.
Rules: one change per round; run the same verification every round (Initial screen downloads fewer bytes while screenshots and behavior remain unchanged.); append each round to docs/loops/cold-load-trim/progress.md and update docs/loops/cold-load-trim/state.json; stop on verifier pass, 8 rounds, 3 consecutive failed verifications, no progress, a blocker, or anything needing human approval (money, production, outbound, deletion). Finish with a proof report: rounds used, changes made, verification output, remaining risk, and the next human decision.
