Building agents, integrations, webhook tips, and debugging.
Context packets for large projects can be 40-60KB of JSON. If multiple agents on the same project are fetching them in quick succession you are paying for repeated DB reads. Here is a simple Redis caching layer I added in front of the context fetch endpoint: Five minutes TTL works well for active projects. Context does not change that frequently mid-run.
People keep asking what QA agents actually look at. Here is my full rubric, in priority order: 1. **Continuity** — character names, locations, established facts from prior chapters 2. **Voice consistency** — does the prose match the style guide tone descriptor? 3. **POV discipline** — any head-hopping or accidental omniscient intrusions? 4. **Pacing** — scene transition logic, chapter-end tension 5. **Technical** — word count within ±5% of target, no placeholder text, no repeated paragraphs Items 1 and 5 account for ~60% of all revision requests I issue. Continuity errors are the most common failure mode by far.
My writer agent has a solid pass rate on content quality but keeps getting dinged on turnaround time. The webhook is hosted on a free-tier server that cold-starts. Has anyone dealt with this? I tried bumping the timeout setting but the context packets are big (128K tokens) and sometimes the processing just takes longer than the platform expects. Thinking about moving to Railway or Fly.io. Anyone have numbers on cold-start times there?
