description	Sync Hypercerts SDK with latest lexicons from the develop branch. Use when updating SDK dependencies, comparing lexicon versions, or reconciling changes between SDK and lexicons repository. Always check the CHANGELOG.md and diffs first to see exactly what changed between versions.

Sync Lexicons Skill

Compare the Hypercerts lexicons repository changes between the version the SDK currently depends on and the latest develop branch, then update SDK files accordingly.

When to Use This Skill

• When updating @hypercerts-org/lexicon dependency in SDK
• When users ask "what changed in lexicons since the SDK version?"
• Before SDK releases to ensure lexicon alignment
• When reconciling SDK imports with new lexicons

How It Works

1. Extract current dependency: Read SDK's packages/sdk-core/package.json for current @hypercerts-org/lexicon version

2. Fetch develop branch: Get latest from lexicons repo develop branch

3. Compare versions: Determine semantic version difference

4. Review CHANGELOG:

   • For changes between normal releases, inspect CHANGELOG.md in the lexicons repo to understand changes between the two versions.

   • For changes with beta pre-releases, CHANGELOG.md is not updated in the lexicons repo, but it is in released packages, so you can download the latest version via:

     tgz=$(npm pack @hypercerts-org/lexicon) && tar zxO package/CHANGELOG.md <$tgz >CHANGELOG.md && rm $tgz
     

5. Generate git diff: Show changes between the two versions in lexicons repo

6. Update SDK files: Modify SDK source files to reflect new lexicon imports/exports

Key Paths

• SDK root: . (current working directory)
• SDK package.json: packages/sdk-core/package.json
• SDK lexicons source: packages/sdk-core/src/lexicons.ts
• Lexicons repo: ../hypercerts-lexicon

Usage

Step 1: Check version of current dependency

OLD_VERSION=$(jq -r '.dependencies["@hypercerts-org/lexicon"] // empty' packages/sdk-core/package.json)
if [ -z "$OLD_VERSION" ]; then
  echo "Error: @hypercerts-org/lexicon dependency not found in packages/sdk-core/package.json" >&2
  echo "Please ensure @hypercerts-org/lexicon is listed under dependencies before running this script." >&2
  exit 1
fi
echo "Current SDK dependency: @hypercerts-org/lexicon@${OLD_VERSION}"

Note: OLD_VERSION is extracted without the v prefix (e.g., 0.10.0-beta.4). When using with git commands, prepend v to match git tag format. The OLD_VERSION variable should be captured and preserved for use in subsequent steps (Step 5). These commands should be executed in the same shell session to maintain variable state, or the variable should be saved to a file or environment variable that persists across command executions.

Step 2: Fetch latest develop and tags

# Ensure the lexicons repository is present in the expected location
if [ ! -d "../hypercerts-lexicon" ]; then
  echo "Error: Lexicons repository not found at ../hypercerts-lexicon" >&2
  echo "Please ensure the repository is cloned in the expected location." >&2
  exit 1
fi

git -C ../hypercerts-lexicon fetch --tags origin

Step 3: Update SDK package.json to exact latest version

# Get the latest version tag from the lexicons repo (strip 'v' prefix for package manager)
NEW_VERSION=$(git -C ../hypercerts-lexicon tag --list 'v*' --sort=-version:refname | head -1 | sed 's/^v//')
echo "Latest lexicon version: ${NEW_VERSION}"

# Update to exact version (no ^ operator) using pnpm add with --save-exact
pnpm --filter @hypercerts-org/sdk-core add --save-exact @hypercerts-org/lexicon@${NEW_VERSION}

Note: NEW_VERSION is now set without the v prefix (e.g., 0.10.0-beta.11) for use with package managers. When using with git commands in subsequent steps, prepend v to match git tag format.

Step 4: Check CHANGELOG.md

After updating the dependency, read the lexicons CHANGELOG to understand what changed:

cat packages/sdk-core/node_modules/@hypercerts-org/lexicon/CHANGELOG.md

Look for:

• Breaking changes that require SDK updates
• Renamed exports (e.g., HELPER_WORK_SCOPE_VERSION_* → WORK_SCOPE_VERSION_*)
• New lexicons added
• Deprecated/removed constants

Step 5: Compare versions and diff

# Use OLD_VERSION from Step 1 and NEW_VERSION from Step 3 (both without the 'v' prefix)
# If running Step 5 independently, re-extract NEW_VERSION:
# NEW_VERSION=$(jq -r '.dependencies["@hypercerts-org/lexicon"]' packages/sdk-core/package.json)

echo "Comparing ${OLD_VERSION} (previous) to ${NEW_VERSION} (updated)"

# Check if versions are identical
if [ "${OLD_VERSION}" = "${NEW_VERSION}" ]; then
  echo "OLD_VERSION and NEW_VERSION are identical; no diff to show."
else
  # Construct git tag names (tags are of the form vX.Y.Z)
  OLD_TAG="v${OLD_VERSION}"
  NEW_TAG="v${NEW_VERSION}"

  # Show files that changed between old and new versions
  git -C ../hypercerts-lexicon diff "${OLD_TAG}..${NEW_TAG}" --stat

  # Show detailed changes in lexicon JSON files
  # Note: `head -200` limits output for readability; remove `| head -200` to see the full diff if needed.
  git -C ../hypercerts-lexicon diff "${OLD_TAG}..${NEW_TAG}" -- '*.json' | head -200
fi

Step 6: Create structured plan and get user approval

CRITICAL: Do NOT proceed beyond this step without explicit user approval.

Based on the CHANGELOG and git diff analysis, create a detailed plan document (specs/lexicon-sync/v{OLD_VERSION}-v{NEW_VERSION}.md) that:

1. Groups changes by logical feature (not by file or lexicon)

   • Each feature should be a self-contained unit of work
   • Examples: "Collection Item Weights", "Work Scope Logic Expressions", "Collection Avatar/Banner"

2. For each feature, document:

   • CHANGELOG reference (PR number, version)
   • What changed in the lexicon
   • SDK tasks needed:
     • Documentation updates
     • Type exports/aliases to add
     • Helper types needed
     • Usage examples to add
   • Validation steps (build, test, type checking)
   • Changeset requirements (bump type according to semantic versioning principles: major/minor/patch, and justification)

3. Order changes logically:

   • Group related changes together
   • Put simpler changes before complex ones
   • Consider dependencies between changes

4. Write the plan to specs/lexicon-sync/v{OLD_VERSION}-v{NEW_VERSION}.md

   • Create the specs/lexicon-sync/ directory if it doesn't exist
   • Use the exact version numbers from package.json

Example plan structure:

# Lexicon Sync Plan: v{OLD} → v{NEW}

Present this plan to the user and ask:

"I've analyzed the changes between v{OLD_VERSION} and v{NEW_VERSION} and created a plan in specs/lexicon-sync/v{OLD_VERSION}-v{NEW_VERSION}.md.

The plan breaks down the sync into {N} logical changes that will be implemented one at a time.

Should I proceed with implementing Change 1: [Feature Name]?"

Present the structured plan to the user and explicitly ask whether to:

• Approve the plan and proceed
• Request modifications to the plan
• Cancel the sync process for now

If the user approves the plan, proceed to the next steps in this skill.

If the user requests modifications, revise the plan based on their feedback, re-present it, and remain in this step until an updated plan is explicitly approved.

If the user declines approval or cancels the sync, stop the sync process, do not execute any further steps in this skill, and summarize the current state and reasons for cancellation.

Wait for explicit user confirmation before proceeding to Step 7.

Step 7: Implement ONE logical change at a time

IMPORTANT: Only work on ONE change from the plan at a time.

For the current change (e.g., "Change 1: Collection Item Weights"):

1. Update method documentation - Focus on documenting the methods users will call:

   • Add/update JSDoc comments on SDK methods (e.g., createCollection(), updateCollection())
   • Add usage examples in method documentation showing new features
   • Document parameters, return values, and behavior
   • Document breaking changes if any
   • Location: packages/sdk-core/src/repository/HypercertOperationsImpl.ts and interfaces

2. Add type exports if needed:

   • Add type aliases for new lexicon types in packages/sdk-core/src/services/hypercerts/types.ts
   • Add helper types for SDK operations (CreateParams, UpdateParams, etc.)
   • Export from appropriate modules
   • Keep type documentation minimal - let method docs do the heavy lifting

3. Update SDK code if needed:

   • Modify operations to support new fields
   • Update validation logic
   • Add helper functions

4. Validate changes:

   pnpm --filter @hypercerts-org/sdk-core format:check
   pnpm --filter @hypercerts-org/sdk-core lint
   pnpm --filter @hypercerts-org/sdk-core typecheck
   pnpm --filter @hypercerts-org/sdk-core build
   pnpm --filter @hypercerts-org/sdk-core test
   

5. Create changeset for this specific change (only after all validation passes):

   pnpm changeset
   

   • Follow guidance from the writing-changesets skill (see .claude/skills/writing-changesets/SKILL.md for detailed instructions on creating and categorizing changesets)
   • Reference the specific feature being added
   • Use an appropriate semantic version bump type (major/minor/patch) according to semantic versioning principles

After completing these steps for the current change:

Ask the user:

"Change {N}: {Feature Name} is complete.

• Documentation added: ✅
• Types updated: ✅
• Format check passing: ✅
• Lint passing: ✅
• Typecheck passing: ✅
• Build passing: ✅
• Tests passing: ✅
• Changeset created: ✅

Should I proceed with Change {N+1}: {Next Feature Name}?"

Repeat Step 7 for each change in the plan, getting approval between each one.

Step 8: Final validation and cleanup

After ALL changes are implemented:

1. Run full test suite:

   pnpm test
   pnpm build
   

2. Review all changesets:

   • Check if multiple changesets should be combined
   • Ensure consistency in messaging
   • Verify bump types are correct

3. Update any top-level documentation:

   • README changes if needed
   • AGENTS.md updates if needed

4. Mark plan as complete:

   • Update the plan file with final status
   • All changes should show ✅ Complete

5. Present final summary to user with:

   • All changes implemented
   • All changesets created
   • Build/test status
   • Any remaining manual steps needed

Common Anti-Patterns to Avoid

Don't Skip Review of the CHANGELOG.md review or diffs

• ❌ Immediately update without reviewing changes
• ✅ Always check CHANGELOG.md first to see exactly what changed between versions
• ✅ Then run git diff to see what actually changed in your codebase

Don't Forget to Rebuild

• ❌ Update imports and ship
• ✅ Run pnpm build to verify type compatibility

What Gets Synced

The sync process focuses on making SDK changes visible and usable to developers. For each logical change:

Documentation Updates

IMPORTANT: Document methods, not types. Users call methods, not types.

1. Method documentation - JSDoc comments on SDK methods explaining new features
   • Focus on createX(), updateX(), getX() methods in HypercertOperationsImpl.ts
   • Document parameters, return values, and behavior
   • Add @example tags showing how to use new fields
2. Usage examples - Code snippets in method docs showing how to use new fields/types
3. Breaking change notes - Clear warnings in method docs about incompatible changes
4. Type documentation - Keep minimal; types should be self-explanatory from method docs

Type System Updates

1. Type aliases - Friendly names for lexicon types (e.g., HypercertClaim = OrgHypercertsClaimActivity.Main)
2. Helper types - SDK-specific types for common operations (e.g., CreateClaimParams)
3. Union types - Combined types for flexible APIs (e.g., ImageInput = string | Blob)

Code Updates (when needed)

1. New lexicons:

   • Add *_LEXICON_JSON imports from @hypercerts-org/lexicon
   • Add to HYPERCERT_LEXICONS array
   • Add NSID to HYPERCERT_COLLECTIONS object if it's a record type

2. Modified lexicons:

   • Update type exports if schema changed
   • Add helper types for new fields
   • Update operations to support new features

3. Removed lexicons:

   • Remove imports and exports
   • Add deprecation notices
   • Maintain backward compatibility if possible

Validation

Each change must pass:

• Formatting (pnpm format:check)
• Linting (pnpm lint)
• TypeScript typechecking (pnpm typecheck)
• TypeScript compilation (pnpm build)
• All existing tests (pnpm test)
• Type export verification

Changesets

Each logical change gets its own changeset:

• minor - New features, backward-compatible changes
• major - Breaking changes (rare, requires migration guide)
• patch - Bug fixes, documentation only (very rare for lexicon syncs)

Iterative Process Summary

Do:

• Work on one logical feature at a time
• Validate, get approval, repeat

Don't:

• Try to sync everything at once in a big batch

This ensures:

• Each change is reviewable in isolation
• Problems are caught early
• Changesets accurately describe what changed
• User has control over the process
