Upgrade Notes Skill

Create comprehensive, action-oriented upgrade documentation for a major Hoist React release. This skill produces two artifacts and validates them via dry-run simulation.

Version: $ARGUMENTS

Phase 0: Setup

  1. •Parse the version from $ARGUMENTS. Normalize to vNN short form and NN.x.x full form.
  2. •Identify the prior major version by reading CHANGELOG.md to find the entry immediately before the target version (e.g. if target is v79, prior is v78.x).
  3. •Determine the git tag range for diffing: v{prior}..v{target} (e.g. v78.1.4..v79.0.0). List available tags with git tag -l 'v*' to find exact tag names.
  4. •Read template.md for the upgrade notes document template.
  5. •Read docs/changelog-format.md for CHANGELOG entry conventions.

Phase 1: Research

Gather all information needed to write accurate documentation. Launch parallel research agents where possible.

1a. Git History Analysis

  • •Run git diff --stat {prior_tag}..{target_tag} to understand scope of changes.
  • •Run git log --oneline {prior_tag}..{target_tag} to see all commits in the release.
  • •Read the existing CHANGELOG entry for the target version to understand what's already documented.

1b. Source File Analysis

Read key source files that commonly change between major versions:

  • •package.json — dependency versions, resolutions
  • •core/XH.ts — singleton API, app-level getters
  • •core/HoistBase.ts — base class lifecycle, decorators
  • •cmp/grid/ — GridModel, Column, grid infrastructure
  • •cmp/form/ — FormModel, FieldModel, FormField
  • •cmp/tab/ — TabContainerModel, TabSwitcher
  • •cmp/layout/ — layout components, LayoutProps
  • •data/ — Store, Field, Filter, Cube, View
  • •styles/ — CSS variables, SCSS mixins
  • •kit/blueprint/ — Blueprint wrappers and re-exports
  • •security/ — HoistAuthModel, auth clients
  • •desktop/cmp/dash/ — DashContainerModel, DashCanvasModel
  • •desktop/cmp/panel/ — Panel, PanelModel

1c. Sample App Upgrade Analysis

Review upgrade commits in sample applications to understand real-world app-level changes required. These apps are available locally (see CLAUDE.local.md for paths):

  • •Toolbox (../toolbox) — canonical reference app, always upgraded first
  • •Additional sample/customer applications listed in CLAUDE.local.md

For each app, search git log for commits referencing the target version:

bash
git -C ../toolbox log --oneline --all --grep="v{NN}" --grep="hoist" --grep="{NN}.0"

Read the key files from upgrade commits: package.json, tsconfig.json, Bootstrap.ts, and any files touching changed APIs.

Important: Only reference Toolbox by name in the upgrade notes (it's the public demo app). Do not mention other sample or customer applications by name — use them only for research and abstracted patterns.

1d. Framework Documentation

If the upgrade involves a major library version change, fetch the official upgrade guide for reference:

  • •Blueprint: https://github.com/palantir/blueprint/wiki/Blueprint-{N}.0
  • •AG Grid: https://www.ag-grid.com/react-data-grid/upgrading-to-ag-grid-{N}/
  • •Highcharts: https://www.highcharts.com/blog/changelog/

Phase 2: Write the CHANGELOG Entry

Audit the Existing Entry

Read the current CHANGELOG entry for the target version. Evaluate against these criteria:

  • • Structure: Uses standard emoji-prefixed section headers (💥 Breaking Changes, 🎁 New Features, 🐞 Bug Fixes, ⚙️ Technical, ✨ Styles, 📚 Libraries) — see docs/changelog-format.md
  • • Breaking Changes: All required app changes are listed as individual bullets (not buried in prose under Technical or other sections)
  • • Completeness: Changes that affect behavior, APIs, or configuration are accounted for (trivial formatting, internal refactors, or tooling changes can be omitted)
  • • Accuracy: Class names, method names, file paths are correct
  • • Tense: Past-tense, action-driven voice ("Enhanced", "Fixed", "Added") — exception: developer instructions use imperative ("Update", "Adjust")
  • • Conciseness: Each bullet is 1-2 lines; detailed instructions belong in upgrade notes
  • • Libraries section: Present for major version bumps with old → new format

Write or Rewrite the Entry

If the entry needs significant changes, rewrite it following the format in docs/changelog-format.md. Key principles:

  • •Breaking Changes section should have a difficulty rating and list every required app change
  • •Each bullet names the specific action concisely — the upgrade notes handle the detail
  • •Include a link to the upgrade notes file: docs/upgrade-notes/v{NN}-upgrade-notes.md
  • •Include a link to the relevant framework upgrade guide (if applicable)
  • •Libraries section lists major dependency version bumps in old → new format

Phase 3: Write the Upgrade Notes

Create docs/upgrade-notes/v{NN}-upgrade-notes.md following the template in template.md.

Content Requirements

Each upgrade step must include:

  1. •What to change — explicit file paths from project root
  2. •Before/after code blocks — with appropriate language tags (typescript, json, scss, bash, etc.)
  3. •Search commands — grep -r "pattern" client-app/src/ to help developers find affected files
  4. •Why — brief explanation of what changed and why (one sentence is usually enough)
  5. •Verification — how to confirm the step was done correctly (where applicable)

Writing Guidelines

  • •Be specific and concrete. Name exact files, classes, methods, and property names.
  • •Use code blocks generously. Developers copy-paste from upgrade guides.
  • •Before/after examples should show realistic code, not pseudocode.
  • •Use element factory style in code examples (not JSX), consistent with Hoist conventions.
  • •Reference Toolbox as the canonical example where helpful (it's the public demo app).
  • •Do not mention sample or customer applications by name, with the exception of Toolbox.
  • •Keep prose minimal between code blocks — this is a recipe, not an essay.
  • •Steps should be ordered logically (build system first, then source code, then cleanup).
  • •The verification checklist at the end should cover all critical functionality.

Update the docs/README.md Index

Add a row to the table in docs/README.md for the new version.

Phase 4: Dry-Run Validation

After writing both artifacts, launch an independent validation agent. This agent stress-tests the upgrade notes by simulating a real upgrade.

Agent Setup

Launch a Task agent (subagent_type: "general-purpose") with these instructions:

You are an "App Upgrade Advisor" agent. Your job is to evaluate upgrade documentation by simulating its use against a real application.

  1. •

    Setup: Check out Toolbox (at ../toolbox) at a commit BEFORE the target hoist-react version was applied. Use git log --oneline to find the last commit before the upgrade. Create a temporary branch for the dry run.

  2. •

    Dry run: Working solely from the upgrade notes file at docs/upgrade-notes/v{NN}-upgrade-notes.md and the app's current source, walk through each step as if advising on a real upgrade. For each step, evaluate:

    • •Is the instruction clear and unambiguous?
    • •Does the "Before" code match what's actually in the app?
    • •Are there files or patterns in the app not covered by the guide?
    • •Would a developer know exactly what to do?
  3. •

    Report: Produce a structured report with:

    • •Gaps: Steps or changes not covered by the guide
    • •Ambiguities: Instructions that could be misinterpreted
    • •Inaccuracies: Before/after examples that don't match reality
    • •Suggestions: Ways to improve clarity Rate each finding as HIGH / MEDIUM / LOW priority.
  4. •

    Cleanup: Restore Toolbox to its original state (checkout original branch, delete temp branch). Do NOT leave any changes behind.

IMPORTANT: Do NOT modify any files in the upgrade notes or CHANGELOG — only report findings.

Handling the Report

Review the agent's findings. Address all HIGH and MEDIUM priority items by updating the upgrade notes and/or CHANGELOG entry. LOW priority items are at your discretion.

Phase 5: Finalize

  1. •Re-read both artifacts one final time to check for consistency between the CHANGELOG entry and the upgrade notes (same version numbers, same list of changes, matching links).
  2. •Verify the docs/README.md index is updated.
  3. •Present a summary to the user of what was created/changed and offer to commit.

Important Notes

  • •This skill produces documentation — it does NOT modify application source code.
  • •The CHANGELOG is a consolidated file appended to on each release. Balance completeness with conciseness. The upgrade notes file is where expanded detail lives.
  • •Always verify code examples against actual source files. Never guess at class names, method signatures, or file paths.
  • •The dry-run validation phase is critical — it catches gaps that are invisible when writing documentation from the "inside out". Do not skip it.
