migration

Plan and implement migrations for data, APIs, configuration, and dependencies while preserving existing data and compatibility. Define rollback steps, check old and new behavior, and handle retries and partial failures during staged transitions.

OriginalShow the original description

Implement reversible compatibility-safe transitions. Use for schema, data, API, protocol, configuration, or dependency migrations requiring rollback and preservation proof.

See how to install

Good for

  • Migrate data while preserving existing records
  • Roll out changes while old and new versions coexist
  • Prepare rollback steps before a migration
  • Check retries and partial failures

  • SKILL.md784 B
  • agents/openai.yaml203 B

SKILL.md (original)

Review the instructions the agent will receive before you install.

Migration

Map current readers, writers, data shape, compatibility window, and ownership before editing.

  • Define forward path and rollback path.
  • Preserve existing data; make destructive steps explicit and separately authorized.
  • Keep mixed-version operation safe where rollout can overlap.
  • Sequence expand, migrate, verify, then contract when applicable.
  • Make retries idempotent and partial failure observable.
  • Verify old and new paths at required transition stages.

Stop after requested stage passes; do not perform later destructive contraction implicitly.

FreeSummary

Delegate code lookup, small edits, and diff reviews to three specialized subagents. Their compact, structured results help conserve the main agent's context, with guidance on when to delegate and when to keep work in the main conversation.

  • Locating definitions and callers
  • Making a focused edit across one or two files
  • Reviewing a diff for bugs

caveman

FreeSummary

Make agent replies shorter and easier to scan by putting answers first and removing filler. Preserves technical details, exact commands, numbers, and essential conditions while keeping the user's chosen language.

  • Reading concise replies in a terminal
  • Getting conclusions before explanations
  • Reducing wording while keeping technical details

caveman-commit

FreeSummary

Create short commit messages using Conventional Commits, a format that labels the type of change. Emphasize intent, keep the subject concise, and include explanatory text when breaking changes, security fixes, data migrations, or reversions require context.

  • Writing a commit message for code changes
  • Standardizing commit message format
  • Documenting breaking changes and migration steps

caveman-compress

FreeSummary

Compress memory files and task lists into shorter wording to reduce input tokens. Keeps code and document structure intact, saves a readable backup separately, and sends the text to the configured model provider.

  • Shortening CLAUDE.md to reduce input tokens
  • Compressing task lists and preference files
  • Keeping readable backups of compressed files

caveman-discover

FreeSummary

Find LLM workflows in a codebase and label them by the job they perform, so Caveman Cloud can separate spending by workflow. Present a labeling proposal for approval, apply focused code changes, and check an affected execution path.

  • Breaking down LLM spending by job
  • Inventorying LLM use in APIs, scheduled jobs, and scripts
  • Separating evaluation spending from other workflows
JuliusBrussee/caveman113.7KUpdated Oct 18, 2026

Review Caveman Cloud spending, latency, errors, and potential improvements using current reports and traces, or individual execution records. Produce findings tied to time windows and trace IDs, while keeping measured costs, estimated opportunities, and verified savings separate.

  • Understanding which workflows drive LLM spending
  • Investigating slow responses and errors
  • Reviewing measured costs and verified savings separately
