last-tag

# Last Tag - Commits Since Last Release Show commits since the last tag in a formatted table with optional details. ## Activation Triggers - "last tag", "last-tag", "since last tag" - "what changed since last release" - "commits since last tag" - "what's new", "unreleased changes" ## Workflow **Important**: Avoid `$()` command substitution in Bash tool - use sequential steps. 1. Fetch tags from remote and get the last tag: ```bash git fetch origin --tags ``` Then get the last tag: ```bash git describe --tags --abbrev=0 ``` Store this value (e.g., `v1.2.3`) for use in subsequent commands. 2. Get commits since that tag with format `date|author|hash|subject` (substitute TAG with actual value): ```bash git log TAG..HEAD --format="%ad|%an|%h|%s" --date=short ``` 3. Check if all commits have the same author - extract unique authors from step 2 output. If only one unique author name appears in all rows, it's a single author. 4. Format output: **If single author** (count = 1): ``` Last tag: v1.2.3 Author: John Doe | Date | Commit | Description | |------------|---------|--------------------------------| | 2025-12-20 | abc1234 | fix: resolve null pointer | | 2025-12-19 | def5678 | feat: add user authentication | ``` **If multiple authors** (count > 1): ``` Last tag: v1.2.3 | Date | Author | Commit | Description | |------------|----------|---------|--------------------------------| | 2025-12-20 | John Doe | abc1234 | fix: resolve null pointer | | 2025-12-19 | Jane Doe | def5678 | feat: add user authentication | ``` **If no tag exists**: ``` No tags found in repository ``` **If no commits since tag**: ``` Last tag: v1.2.3 No commits since this tag ``` ## Interactive Details After displaying the table, use AskUserQuestion: ``` question: "Show commit details?" header: "Details" options: - label: "All commits" description: "Show full details for each commit" - label: "None" description: "Skip details" - label: "Specific commit" description: "Enter commit hash to inspect" ``` **If "All commits"**: For each commit, run: ```bash git show --stat --format="Commit: %h%nAuthor: %an <%ae>%nDate: %ad%n%n%s%n%n%b" --date=short HASH ``` This shows: commit hash, author with email, date, subject, body, and file change stats. **If "None"**: End. **If "Specific commit"** or user enters hash via "Other": Run the same `git show` command for that commit only.
