Create Release Branch Command

Workflow: /create-release-branch → /create-release → /merge-release → /release

Context

Working directory: !pwd

Repository: !git rev-parse --show-toplevel 2>/dev/null || echo "(not in a git repository)"

Current branch: !git branch --show-current 2>/dev/null || echo "(not in a git repository)"

Arguments provided: $ARGUMENTS

Latest release (deterministic — <kind> <ref> <version>): !bash "${CLAUDE_PLUGIN_ROOT}/shared/resolve-latest-release.sh" 2>/dev/null || echo "(resolver unavailable)"

Release terminology — use the definitions in ${CLAUDE_PLUGIN_ROOT}/shared/release-concepts.md. "Latest release" is the value printed above.

Your Task

This skill is a thin dispatcher over the deterministic shell library at ${CLAUDE_PLUGIN_ROOT}/shared/release/. Do not re-derive parsing or version logic in prose — call the scripts and surface their structured output.

Step 0 — Pre-flight: verify git repo

git rev-parse --is-inside-work-tree 2>/dev/null

If this returns non-zero, stop with the standard "not in a git repository" message that tells the user to cd into a service repo first (see Working directory: in Context above).

Step 1 — Parse arguments

Run the parser:

bash "${CLAUDE_PLUGIN_ROOT}/shared/release/parse-args.sh" \
  --skill=branch-create --json -- $ARGUMENTS

Possible outcomes:

• Exit 0 — fully parsed. The output JSON has version, source, source_kind populated.
• Exit 10 — ambiguous; the missing array names the field(s) the user didn't supply (typically ["version"]).
• Exit 20 — bad input. Show the errors array and stop.

Step 2 — Resolve missing fields interactively

If the parser returned exit 10 with missing containing version:

1. Run bash "${CLAUDE_PLUGIN_ROOT}/shared/release/version-suggest.sh" --json to get a recommended next version grounded in the current repo's tag/branch state. This script fetches remote tags first so the suggestion is based on the authoritative tag set. Watch its stderr: if it emits a [stale-tags] or [no-remote] marker, the tag fetch failed or was skipped — surface that marker to the user before presenting the recommendation, since the suggested version may be based on stale local tags. Do not block on it; continue to the recommendation.

2. Use AskUserQuestion to present:

   • The recommended value with its reason as the (Recommended) option.
   • Each entry from alternatives as additional options.

   Critical: the suggestion must come from version-suggest.sh run in the current working tree — never carry over a version seen earlier in the conversation from a different repo.

3. Re-run parse-args.sh with the chosen version included in $ARGUMENTS.

If source was not supplied, default to origin/master (parse-args already does this). The user may override via the second positional argument or the [email protected] syntax.

Step 3 — Show plan and confirm

Run the action script in plan mode:

bash "${CLAUDE_PLUGIN_ROOT}/shared/release/branch-create.sh" \
  --version=<v> --source=<s> --source-kind=<k> --plan --json

Print the human-readable plan (re-run without --json for display, or render the JSON yourself). Use AskUserQuestion to confirm before applying.

Step 4 — Record audit, then apply

Pushing to release/* is gated by git-mutation-guard.sh and requires a security-auditor confirmation. Record one immediately before invoking the action script:

bash "${CLAUDE_PLUGIN_ROOT}/hooks/record-audit.sh"

Then run apply:

bash "${CLAUDE_PLUGIN_ROOT}/shared/release/branch-create.sh" \
  --version=<v> --source=<s> --source-kind=<k> --apply --json

If --apply exits non-zero, surface stderr to the user verbatim and stop.

Step 5 — Report and suggest next steps

On success, show:

✓ Release Branch Created
  branch: release/<v>
  source: <ref>

Next:
  /create-release          # open PR to master
  /merge-release           # merge once approved
  /release                 # tag + GitHub release

Important Notes

• Single message execution — run all of the above in one assistant turn using parallel tool calls where independent.
• No per-step git invocations in prose — every git/branch/version operation goes through the shell library. The library is the source of truth.
• Version normalization happens in the parser — pass $ARGUMENTS to it raw; do not strip or add the v prefix yourself.
• Audit gate — record-audit.sh must run immediately before the action script; do not run anything between them that could change HEAD or branch.
