+
+# Bump CLI Compatibility Manifest
+
+Updates `internal/build/cli-compat.json` with new AppKit and Agent Skills versions, validates the result, and creates a PR.
+
+## Arguments
+
+Parse the user's input for optional named flags:
+
+- `--appkit <version>` → AppKit version (e.g. `0.28.0`)
+- `--skills <version>` → Agent Skills version (e.g. `0.1.6`)
+- No args → auto-detect latest versions from GitHub tags
+
+Versions should be provided **without** the `v` prefix (e.g. `0.28.0`, not `v0.28.0`). If provided with the prefix, strip it.
+
+## Workflow
+
+### Step 1: Resolve versions
+
+If both `--appkit` and `--skills` versions were provided, skip to Step 2.
+
+For any missing version, fetch the latest tag from GitHub:
+
+```bash
+# Latest appkit version (strip leading 'v')
+gh api repos/databricks/appkit/tags --jq '.[0].name' | sed 's/^v//'
+
+# Latest skills version (strip leading 'v')
+gh api repos/databricks/databricks-agent-skills/tags --jq '.[0].name' | sed 's/^v//'
+```
+
+Show the resolved versions to the user and ask:
+
+> The latest versions are:
+> - AppKit: `{appkit_version}`
+> - Agent Skills: `{skills_version}`
+>
+> Have these versions been evaluated (evals passed with no regressions)?
+
+**Do NOT proceed until the user confirms.** If the user says no or wants different versions, ask them to provide the correct versions.
+
+### Step 2: Validate tags exist
+
+Verify that the corresponding Git tags exist on GitHub. For AppKit, also validate the `template-v` tag (used by `apps init`):
+
+```bash
+# AppKit release tag
+gh api repos/databricks/appkit/git/ref/tags/v{appkit_version} --jq '.ref'
+
+# AppKit template tag (used by apps init)
+gh api repos/databricks/appkit/git/ref/tags/template-v{appkit_version} --jq '.ref'
+
+# Agent Skills tag
+gh api repos/databricks/databricks-agent-skills/git/ref/tags/v{skills_version} --jq '.ref'
+```
+
+If any tag doesn't exist, report the error and stop.
+
+### Step 3: Read current manifest
+
+Read `internal/build/cli-compat.json`. Note the current versions and the list of versioned entries.
+
+### Step 4: Determine update type
+
+Ask the user:
+
+> Do any of these apply?
+> - **AppKit**: The new templates require new CLI logic in `apps init` (e.g. new flags, prompts, or template handling that older CLIs don't have)
+> - **Skills**: The new skills version uses CLI commands that older CLIs don't support
+>
+> If **neither** applies, this is a non-breaking bump (default).
+
+- **No breaking changes** (default): proceed to Step 4a.
+- **Breaking changes**: proceed to Step 4b.
+
+### Step 4a: No breaking changes (update in-place)
+
+Update the **highest versioned entry** to the new appkit and skills versions. Do NOT add new versioned keys. The manifest is range-based: updating the highest entry automatically covers all CLI versions in that range.
+
+Write the updated `internal/build/cli-compat.json`.
+
+### Step 4b: Breaking changes (add new entry)
+
+Ask the user for the **minimum CLI version** that supports the new features.
+
+Add a new entry keyed to that CLI version with the new appkit and skills versions. Keep older entries unchanged so older CLI binaries stay compatible.
+
+Write the updated `internal/build/cli-compat.json`.
+
+### Step 5: Validate
+
+Run the Go tests to ensure the manifest is well-formed:
+
+```bash
+go test ./libs/clicompat/... -run TestEmbeddedManifest -v
+```
+
+If validation fails, show the errors and fix them before proceeding.
+
+### Step 6: Create branch, commit, and PR
+
+```bash
+# Create a new branch from the current branch (or main)
+git checkout -b bump-cli-compat-appkit-{appkit_version}-skills-{skills_version}
+
+# Stage and commit
+git add internal/build/cli-compat.json
+git commit -s -m "Bump cli-compat to appkit {appkit_version}, skills {skills_version}"
+
+# Push and create PR
+git push -u origin HEAD
+gh pr create \
+ --title "Bump cli-compat to appkit {appkit_version}, skills {skills_version}" \
+ --body "$(cat <<'EOF'
+## Summary
+Bump `cli-compat.json` to use:
+- AppKit `{appkit_version}`
+- Agent Skills `{skills_version}`
+
+## Checklist
+- [ ] Evals passed with no regressions
+- [ ] `go test ./libs/clicompat/... -run TestEmbeddedManifest` passes
+EOF
+)"
+```
+
+Show the PR URL to the user when done.
+
+## Examples
+
+### Example: With explicit versions
+```
+/bump-cli-compat --appkit 0.28.0 --skills 0.1.6
+```
+Validates tags exist (including `template-v0.28.0`), updates manifest, creates PR.
+
+### Example: Auto-detect latest
+```
+/bump-cli-compat
+```
+Fetches latest tags, asks for eval confirmation, then updates and creates PR.
+
+### Example: Only bump AppKit
+```
+/bump-cli-compat --appkit 0.28.0
+```
+Auto-detects latest skills version, asks for confirmation, then updates both.
