// features

Built for pipelines,
not just developers.

Bumpkit is designed to be called in CI — not just by humans reading docs.

⚡
Confidence scoring
Every response includes a 0–1 confidence score. Agents can decide whether to auto-publish or hand off to a human review step.
🧹
Handles messy commits
Works with any commit style, not just Conventional Commits. Low-signal messages are filtered and flagged — not silently dropped.
📦
Structured JSON output
Sections, entries, bump type, reasoning — all structured. Plus a pre-formatted string for humans. Machines and people both get what they need.
🔄
Partial responses
Low-confidence results return status: partial — not an error. Agents get usable data with clear warnings, instead of crashing or silently succeeding.
📡
Rate limit headers
Every response includes X-RateLimit headers so agents can track remaining quota and schedule retries without hitting walls.
🔗
Commit deep links
Pass a repository URL and Bumpkit auto-generates GitHub, GitLab, or Bitbucket commit links directly in the changelog output.
