Skills evolve: new parameters, better defaults, or a changed output shape. Without versioning, updates break workflows and leave users guessing what changed. This guide covers versioning and updating OpenClaw skills: semantic versioning, breaking vs non-breaking changes, migration paths, and how to keep document and PDF integrations (e.g. iReadPDF) compatible so US professionals can adopt updates without surprise breakage.
Summary Use semantic versioning (major.minor.patch) for skills. Bump major when inputs or outputs change in a breaking way; minor for new optional params or additive output; patch for fixes and internal tweaks. Document changelogs and migration steps. When document pipelines are involved, version the contract (e.g. doc summary format v1) so iReadPDF and consuming skills stay in sync across updates.
Why Version Skills
Unversioned skills create confusion and breakage. A user or workflow that relied on "get_document_summary returns summary and key_points" may break when you add a new required field or rename one. Versioning gives you a contract: "This is get_document_summary v1.2; here's what it accepts and returns." When you release v2, you document what changed and how to migrate so consumers can plan.
For US professionals who chain skills (morning brief, meeting prep, task suggestion), versioning means predictable upgrades: you know which skills to test and what to change when you move to a new version. Document pipelines that feed those skills—e.g. iReadPDF output—benefit from the same idea: a versioned summary format so every skill knows what to expect.
Semantic Versioning for Skills
Use a three-part version: major.minor.patch (e.g. 1.2.3).
- Major (X.0.0). Breaking changes: removed or renamed parameters, changed output shape, removed behavior that callers relied on. Consumers must update their code or config to work with the new version.
- Minor (x.Y.0). Additive, backward-compatible changes: new optional parameters, new optional output fields, new behavior that doesn't remove or change existing behavior. Existing callers keep working; new callers can opt in.
- Patch (x.y.Z). Bug fixes, performance improvements, internal refactors that don't change the public contract. No caller changes needed.
Example: get_document_summary v1.0 returns { summary, key_points }. If you add an optional doc_id in the output, that's minor (1.1.0). If you rename key_points to bullets, that's breaking—bump to 2.0.0 and document the migration (e.g. "map bullets to key_points in your code or upgrade to the new field name").
Breaking vs Non-Breaking Changes
Classify every change so you bump the right segment.
Breaking (major bump):
- Removing or renaming an input parameter.
- Making an optional parameter required.
- Removing or renaming an output field.
- Changing the type or structure of an output (e.g. key_points from array of strings to array of objects).
- Changing default behavior in a way that existing callers rely on (e.g. "we used to return empty array on error; now we throw").
Non-breaking (minor or patch):
- Adding a new optional input parameter with a default.
- Adding a new optional output field.
- Adding new behavior behind a flag or optional param.
- Fixing a bug that made the skill not match its documented behavior.
- Performance or internal changes with no contract change.
When your skill consumes document data (e.g. from iReadPDF), treat the document contract as part of your skill's contract. If the summary format changes in a breaking way, either your skill must version up and document the new expected shape, or the doc pipeline must maintain backward compatibility (e.g. still emit the old fields for a transition period).
Changelogs and Migration Notes
Every release should have a changelog entry and, for major versions, migration notes.
- Changelog. List what changed: new features, fixes, and breaking changes. Link to the version tag or release so users can see exactly what they're getting.
- Migration notes for major versions. Describe what broke and how to fix it. Examples: "key_points renamed to bullets; update your compose_brief skill to read bullets" or "Parameter time_range is now required; add it to your workflow config."
- Deprecation warnings. When you plan to remove something in the next major version, deprecate it first: keep it working but log a warning or document "deprecated, will be removed in v2." Give users a window to migrate.
For document-related skills, note when the expected doc summary format changes. If iReadPDF or your pipeline starts emitting a new schema, document which skill versions support which schema so users can pin or upgrade consistently.

Document and PDF Contract Versioning
Document and PDF workflows often feed multiple skills (brief, meeting prep, task suggestion). Version the document contract separately so all parties stay aligned.
- Contract as a spec. Define "Document summary format v1: summary (string), key_points (array of strings), doc_id (optional)." Skills that consume doc summaries depend on "document summary format v1" (or v2). When you evolve the format, you version the contract (v2) and list what changed.
- Producer and consumer alignment. iReadPDF or your summarization pipeline produces output that matches the contract version. Consuming skills declare "I need document summary format v1." The orchestrator or installer can check that producer and consumers are compatible.
- Transition period. When moving to a new contract (e.g. v2 with extra fields), the producer can emit both old and new fields for a while so existing skills keep working while others migrate. After a deprecation period, drop the old fields and bump the contract version.
That way, versioning and updating OpenClaw skills stays consistent with how document data flows: one versioned contract, many skills that depend on it.
Update and Rollback Strategies
How you deliver and roll back updates affects reliability.
- Staged rollout. Roll out new skill versions to a subset of users or workflows first. Monitor for errors and performance; if all looks good, broaden the rollout. For major versions, consider a canary or beta channel.
- Rollback. Keep previous versions available (e.g. get_document_summary v1.2 and v2.0 both installable). If v2 causes issues, users can pin back to v1.2 until they're ready to migrate. Document how to pin or switch version in your skill store or config.
- Automated tests. Run integration tests that call the skill with known inputs and assert on outputs. When you change the skill, run the tests; if you've broken the contract, tests fail before users do. For document-consuming skills, include tests with sample iReadPDF-style output so format changes are caught.
Pinning and Dependency Ranges
Users and workflows need to express which version(s) of a skill they accept.
- Exact pin. "get_document_summary 1.2.0" — only that version. Safe but you miss patches and minors unless you update the pin.
- Range. "get_document_summary ^1.2.0" (compatible with 1.2.0 up to but not including 2.0.0) or ">=1.2.0 <2.0.0." Lets you get patches and minors automatically while avoiding breaking changes.
- Document dependencies in the skill. In the skill's manifest or README, list "Requires: document summary format v1" or "Requires: get_calendar ^2.0." That way the orchestrator or marketplace can check compatibility before running.
When document pipelines are in the loop, pin or range the document contract version too. For example: "This workflow requires document summary format ^1." Then iReadPDF and all skills using that format stay compatible as long as the contract stays within the range.
Conclusion
Versioning and updating OpenClaw skills with semantic versioning, clear breaking vs non-breaking rules, and changelogs and migration notes keeps automation stable and upgradable. Version document and PDF contracts (e.g. summary format) so producers like iReadPDF and consuming skills stay in sync. Use update and rollback strategies and dependency ranges so US professionals can adopt new versions with confidence and roll back when needed.
