For founders and product engineers shipping with coding agents

Your customers already told you what to build.

Paste tickets, calls, churn notes, sales objections, and bug reports. Coherence turns them into evidence-backed specs and prompts your coding agent can execute.

How it works

From customer noise to build-ready context.

Sample data
01

Paste the mess

Tickets, calls, churn notes, and objections — pasted as-is, no cleanup required.

Support ticket · Zendesk

csv import keeps timing out on our contact list (14k rows), tried 3x this morning. we cannot get ready for our BF sale if this doesnt work. this is urgent!!

02

Get evidence-backed workstreams

Claude extracts signals, embeds cluster them, and scoring ranks the result.

Ready for handoff

03

Hand off to your agent

Every spec ships with the agent-ready prompt your coding agent can execute.

# Implement: Fix CSV import for large contact lists

Why this matters

Your agent is not the bottleneck. Context is.

Claude Code, Cursor, and Codex can ship once the work is clear. But vague product prompts create vague product work. Coherence keeps the customer evidence attached all the way from feedback to implementation.

What agents usually get

"fix the csv import bug, it keeps failing for some users"

What Coherence hands offSample data

Fix CSV import for large contact lists — imports above 5-6k rows time out with no usable error.

"csv import keeps timing out on our contact list (14k rows), tried 3x this morning. we cannot get ready for our BF sale if this doesnt work. this is urgent!!"

Bramblewood Goods$42,000 ARR

A 15k-row file imports within the existing timeout budget

Feedback is scattered.

Tickets, calls, Slack threads, and churn notes all point in different directions.

Specs lose the receipts.

By the time work reaches an agent, the original customer context is gone.

Agents need better handoffs.

A vague implementation prompt produces vague product work.

Outputs

Outputs your coding agent can actually use.

# Implement: Fix CSV import for large contact lists

## Problem

Imports above roughly 5-6k rows time out or fail without a usable error message. One account has issued a 30-day cancellation notice over repeated failures during their busiest season.

Impact: $81,600 ARR across 3 accounts — one active churn risk.

### Evidence

“csv import keeps timing out on our contact list (14k rows)… this is urgent.” — Bramblewood Goods ($42,000 ARR)

“Bug: CSV import silently drops rows with commas inside quoted fields.” — Cobalt Fitness ($15,600 ARR)

## Implementation

1. Stream large-file processing

A 15k-row file imports successfully within the existing timeout budget

Failed rows are reported individually with row number and reason

Why not just Claude

Claude can analyze feedback once. Coherence remembers.

You can paste everything into Claude. Once or twice. But the context disappears, evidence gets mixed with opinion, and every build handoff starts from scratch. Coherence gives you reusable workstreams, evidence-backed specs, and repeatable agent prompts.

Pasting into Claude
  • one-off analysis
  • manual context every time
  • evidence easy to lose
  • prompt quality varies
  • no product memory
Working in Coherence
  • reusable workstreams
  • receipts attached
  • consistent specs
  • agent-ready prompts
  • product memory

Start with paste. Connect tools later.

Coherence does not need billing data or OAuth on day one. Paste feedback first. Once the workflow earns trust, connect support, CRM, revenue, issue trackers, or MCP handoff tools to enrich prioritization.
