# Agentic CI with a known cost before every run

Promigence gives every agentic CI job a warm environment forked from a verified snapshot of your repo, so an agent starts at a built tree rather than at a `git clone`. Most of an agent-heavy CI bill is repeated setup. Forking removes it, and a quote before each run keeps the monthly number predictable.

**Who this is for:** Platform teams running coding agents against their own repositories in CI.

## What breaks today
### Setup is most of the job
A five-minute agent task behind a ninety-second install is 30% overhead, paid on every job.

### The bill scales with enthusiasm
Agentic CI usage grows the moment it works, and per-second billing means the finance conversation happens afterwards.

### Flaky environments look like flaky agents
A dependency that fails to resolve at 3am produces a red build nobody can attribute, and trust erodes in the agent rather than the fleet.

## What changes with Promigence
### A snapshot per branch, rebuilt when the lockfile moves
So most pushes start from a snapshot that is already built and verified.

### Quote and cap per pipeline
Every workflow knows its ceiling before it starts, and a runaway loop is refused rather than invoiced.

### Environment failures show up as environment failures
Red builds get a cause attached, which is the only way an agent-driven pipeline keeps anyone's trust.

## One step in a GitHub Actions workflow
```yaml
- name: Agent pass on the PR
  run: |
    promigence run \
      --snapshot app --secret ANTHROPIC_API_KEY \
      --count 1 --cap 0.50 --timeout 10m --json \
      -- sh -c "cd /work/repo && git fetch -q origin ${GITHUB_SHA} && git checkout -q ${GITHUB_SHA} && claude -p 'fix the failing tests in this diff'"
  env:
    PROMIGENCE_API_KEY: ${{ secrets.PROMIGENCE_API_KEY }}
```
