ac-tools-milestone

name	ac-tools-milestone
description	Validates backlog section completion, then squashes and tags or identifies gaps. Generates milestone and release notes. Triggers on keywords: milestone, release notes, tag release, validate backlog
project-agnostic	true
allowed-tools	["Read","Edit","Bash","Grep","Glob","Write"]

Validate section completion in backlog, then either release or identify gaps.

Compatibility Note

This pi wrapper preserves the original milestone workflow while treating confirmation points as explicit manual checkpoints in the current chat instead of a runtime interactive-question dependency.

All arguments are optional with smart defaults.

Argument Parsing

Parse $ARGUMENTS into:

Variable	Source	Required	Default
BACKLOG_PATH	1st arg	No	Auto-detect: BACKLOG.md, specs/backlog.md, or skip
SECTION	2nd arg	No	Latest incomplete section, or skip if no backlog
BASE_BRANCH	3rd arg	No	origin/main (fetches first)
VERSION	4th arg (if not quoted)	No	Auto-bump from VERSION file or latest git tag
VALIDATION_PROMPT	Last quoted string "..."	No	Auto-derive from checklist
SKIP_TAG	--skip-tag flag	No	false (tags created by default)
AUTO_MODE	--auto flag	No	false (confirmation gates enabled)
WITH_SQUASHED_COMMITS	--with-squashed-commits flag	No	false (squashed commits list excluded by default)

Parsing Rules:

• If an argument starts and ends with ", treat as VALIDATION_PROMPT
• Version is optional; if 4th arg is quoted, there's no version
• If --skip-tag flag is present anywhere in arguments, set SKIP_TAG=true
• If --with-squashed-commits flag is present anywhere in arguments, set WITH_SQUASHED_COMMITS=true
• If --auto flag is present anywhere in arguments, set AUTO_MODE=true (skips confirmation gates)
• Empty $ARGUMENTS triggers full auto-detect mode

Phase 0: Smart Defaults Resolution

When NO arguments provided:

0.1 Fetch Remote

git fetch origin main || git fetch origin master

0.2 Determine BASE_BRANCH

# Try origin/main first, fallback to origin/master
git show-ref --verify --quiet refs/remotes/origin/main && echo "origin/main" || echo "origin/master"

0.3 Auto-Detect BACKLOG_PATH

Search in order:

1. BACKLOG.md (root)
2. specs/backlog.md
3. docs/backlog.md
4. backlog.md

If none found → SKIP backlog validation (proceed without backlog)

0.4 Auto-Detect SECTION (if backlog exists)

Find first incomplete section (has - [ ] items). If all complete → use most recent section.

0.5 Auto-Detect VERSION

If SKIP_TAG=false: Priority order:

1. VERSION file → parse, increment patch: X.Y.Z → X.Y.(Z+1), prefix with v
2. Latest git tag matching v*.*.* → increment patch
3. Default: v0.1.0

If SKIP_TAG=true: Set VERSION="" (no version/tag will be created)

0.6 CHANGELOG Consistency Check (Critical for No-Args Mode)

# Check if CHANGELOG.md exists and has [Unreleased] content
if [ -f CHANGELOG.md ]; then
  grep -A 100 "\\[Unreleased\\]" CHANGELOG.md | grep -E "^- |^### " | head -20
fi

If CHANGELOG [Unreleased] is EMPTY but commits exist since BASE_BRANCH:

CHANGELOG SYNC REQUIRED

Commits since {BASE_BRANCH}:
  {commit list}

But CHANGELOG.md [Unreleased] section is empty.

Please update CHANGELOG.md with these changes before proceeding.

-> STOP and wait for user to update changelog.

If CHANGELOG [Unreleased] has content -> proceed.

0.7 Project-Specific Enforcement

Check if AGENTS.md contains project-specific rules:

test -f AGENTS.md && echo "exists" || echo "none"

If exists:

1. Read AGENTS.md content
2. Parse and store rules for validation in Phase 4.5
3. Common rules to detect:
   • no emojis / DO NOT use emojis -> flag emoji restrictions
   • project-agnostic / anonymous -> flag content anonymity requirements
   • relative symlinks -> flag symlink requirements

Store parsed rules as PROJECT_RULES for later validation.

Phase 1: Pre-Flight Checks

1. Git state: Must be clean (no uncommitted changes)
2. Commits exist: Must have commits since BASE_BRANCH
3. CHANGELOG exists: CHANGELOG.md must exist with [Unreleased] section
4. Backlog exists (if path provided): File at BACKLOG_PATH must exist
5. Section exists (if backlog provided): Section SECTION must be found in backlog

If any fail → STOP with specific error message.

Phase 2: Extract Checklist (if backlog provided)

1. Read backlog file at BACKLOG_PATH
2. Find section matching SECTION (patterns: #### 1.2, ### Phase 1.2, ## 1.2)
3. Extract ALL checklist items until next section:
   • - [ ] = unchecked
   • - [x] = checked
4. Report: Found X items (Y checked, Z unchecked)

If no backlog: Skip to Phase 4 with auto-approval path.

Phase 3: Validate Implementation (if backlog provided)

If VALIDATION_PROMPT provided:

Use it as explicit criteria. Spawn validation agent with prompt:

VALIDATE: {VALIDATION_PROMPT}

For each criterion, search codebase and report:
- Status: FOUND | MISSING
- Evidence: file:line references
- Notes: any issues

If NO VALIDATION_PROMPT:

For each UNCHECKED item (- [ ]):

1. Parse item to identify expected:

   • Files/components (look for nouns)
   • Interfaces/functions (look for code terms)
   • Tests (if mentioned)

2. Search codebase:

   • Grep for key terms
   • Glob for expected file patterns
   • Check test directories

3. Classify:

   • IMPLEMENTED: Found despite unchecked
   • MISSING: No evidence found

Phase 4: Decision Gate

Path A: No Backlog (Changelog-Only Validation)

Display:

✅ CHANGELOG Validated

Changes since {BASE_BRANCH}:
- {N} commits
- Key changes: {summary}

CHANGELOG [Unreleased] entries:
{entries}

Release Configuration:
- Base: {BASE_BRANCH}
- Version: {VERSION or "(no tag)" if SKIP_TAG=true}
- Commits to squash: N

Proceed with squash + tag? (yes/no)

If AUTO_MODE=true: Skip confirmation, proceed directly to squash/tag.

→ On "yes" (or auto): proceed to squash/tag.

Path B: Backlog - ALL COMPLETE (all items implemented or checked)

Display:

✅ Section {SECTION} COMPLETE

Validated Items:
- [x] Item 1 - evidence: file:line
- [x] Item 2 - evidence: file:line
...

Release Configuration:
- Base: {BASE_BRANCH}
- Version: {VERSION or "(no tag)" if SKIP_TAG=true}
- Commits to squash: N
- CHANGELOG: [Unreleased] → [{VERSION or section name if SKIP_TAG=true}]

Proceed with squash? (yes/no)

If AUTO_MODE=true: Skip confirmation, proceed directly.

On "yes" (or auto):

1. Update backlog: mark all items [x], add checkmark to section header
2. Update CHANGELOG.md:
   • Move all entries from [Unreleased] to new [{VERSION}] - {YYYY-MM-DD} section
   • Keep empty [Unreleased] section at top
   • If no VERSION provided or SKIP_TAG=true, use section name as header
3. Commit: docs: mark {SECTION} as completed
4. Create backup: {branch}-backup/{YYYY}/{MM}/{DD}/001
5. Soft reset to BASE_BRANCH
6. Generate Conventional Commit message (see Phase 4B)
7. Create squashed commit with generated message
8. If VERSION and SKIP_TAG=false: create annotated tag

→ Proceed to Phase 5: Push Confirmation

Phase 4B: Conventional Commit Message Generation

Generate a standardized commit message following Conventional Commits extended format.

4B.1 Analyze Changes

# Get full diff for analysis
git diff {BASE_BRANCH}..HEAD --stat
git diff {BASE_BRANCH}..HEAD --name-status

4B.2 Determine Commit Type

Parse changed files and categorize by primary change type:

Type	When to Use
feat	New feature or capability added
fix	Bug fix
docs	Documentation only changes
chore	Maintenance, deps, configs (no production code)
refactor	Code restructuring without behavior change
test	Adding or modifying tests
style	Formatting, whitespace, linting
perf	Performance improvements
build	Build system or external dependencies
ci	CI/CD configuration changes

Selection Priority:

1. If ANY feat changes exist -> type = feat
2. Else if ANY fix changes exist -> type = fix
3. Else use dominant change type

4B.3 Determine Scope

Analyze changed file paths to identify scope:

# Get unique top-level directories/components
git diff --name-only {BASE_BRANCH}..HEAD | cut -d'/' -f1-2 | sort -u

Scope Rules:

• Single component modified -> use component name (e.g., commands, skills)
• Multiple related components -> use parent (e.g., core)
• Unrelated changes -> omit scope or use release
• Version/release changes -> scope = release or version number

4B.4 Generate Commit Title

Format: <type>(<scope>): <description>

Description Rules:

• Imperative mood ("add" not "added")
• Lowercase first letter
• No period at end
• Max 72 characters total
• Summarize the main purpose

Examples:

• feat(commands): add milestone validation workflow
• fix(parser): handle empty input gracefully
• docs(readme): update installation instructions
• chore(deps): bump typescript to v5.3

4B.5 Generate Commit Body

Structure the body with these sections (include only non-empty):

## Added
- New feature 1
- New feature 2

## Changed
- Modified behavior 1
- Updated component 2

## Fixed
- Bug fix 1
- Issue resolution 2

## Removed
- Deprecated item 1

Content Generation:

1. Parse git diff {BASE_BRANCH}..HEAD file by file
2. Categorize each file's changes:
   • New files -> Added
   • Modified files -> Changed (or Fixed if bug-related)
   • Deleted files -> Removed
3. Summarize meaningful changes (not every line)
4. Reference file paths where helpful

4B.6 Include Original Commits (Optional)

Only if WITH_SQUASHED_COMMITS=true, append squashed commit references:

# Get original commit messages
git log --oneline {BASE_BRANCH}..HEAD

Format as:

Squashed commits:
- {sha7} {message}
- {sha7} {message}
- {sha7} {message}

If WITH_SQUASHED_COMMITS=false (default): Omit this section entirely from the commit message.

4B.7 Complete Message Template

<type>(<scope>): <description>

## Added
- {additions}

## Changed
- {changes}

## Fixed
- {fixes}

## Removed
- {removals}

<!-- Only if WITH_SQUASHED_COMMITS=true -->
Squashed commits:
- {sha} {message}
- {sha} {message}
<!-- End conditional -->

4B.8 Commit Message Example

feat(milestone): add validation workflow with smart defaults

## Added
- Smart defaults resolution for all arguments
- CHANGELOG consistency check
- AGENTS.md validation
- Push confirmation gate

## Changed
- Refactored argument parsing to support quoted strings
- Updated backup branch naming format

## Fixed
- Backlog detection now searches multiple locations

Path C: Backlog - INCOMPLETE (missing items)

Display:

❌ Section {SECTION} INCOMPLETE

Missing:
1. {item} - {what's missing}
2. {item} - {what's missing}

Implemented but unchecked:
1. {item} - {evidence}

Options:
(A) Create /spec for missing items
(B) Abort - review manually

On "A": Output spec creation commands:

Missing items require specs:

/skill:ac-workflow-spec CREATE {item-1-title}
/skill:ac-workflow-spec CREATE {item-2-title}

On "B": STOP cleanly.

Phase 4.5: AGENTS.md Validation (Pre-Push Gate)

If PROJECT_RULES were parsed in Phase 0.7, validate all changes against AGENTS.md rules:

4.5.1 Get Changed Files

git diff --name-only {BASE_BRANCH}..HEAD

4.5.2 Validate Against PROJECT_RULES

For each rule detected, run validation:

Emoji Check (if emoji restriction detected):

# Check all changed .md files for emoji characters
git diff {BASE_BRANCH}..HEAD -- '*.md' | grep -P '[\x{1F300}-\x{1F9FF}]' || echo "clean"

Project-Agnostic/Anonymous Check (if anonymity rule detected):

# Check for personal identifiers, hardcoded usernames, local paths
git diff {BASE_BRANCH}..HEAD | grep -iE '(/Users/[a-z]+|/home/[a-z]+|@[a-z]+\.com)' || echo "clean"

Symlink Check (if symlink rule detected):

# Check for absolute symlinks in changed files
for f in $(git diff --name-only {BASE_BRANCH}..HEAD); do
  if [ -L "$f" ]; then
    target=$(readlink "$f")
    [[ "$target" = /* ]] && echo "ABSOLUTE: $f -> $target"
  fi
done

4.5.3 Violation Handling

If ANY violations found:

AGENTS.md VIOLATIONS DETECTED

The following changes violate project-specific rules:

Rule: {rule description}
Violations:
  - {file}: {violation details}
  - {file}: {violation details}

Rule: {rule description}
Violations:
  - {file}: {violation details}

Fix these violations before proceeding with release.

-> STOP - Do not proceed to Phase 5.

If NO violations -> proceed to Phase 5.

Phase 5: Push Confirmation

After successful squash/tag, display:

## Release Prepared Locally

Commit: {sha} {message}
Branch: {branch}
Tag: {VERSION} (if created, otherwise "(none)")
Backup: {backup-branch}

Push to origin?

Commands to execute:
  git push --force-with-lease origin {branch}
  git push origin {VERSION}  # if tag created (SKIP_TAG=false)

Proceed with push? (yes/no)

If AUTO_MODE=true: Skip confirmation, proceed directly with push.

On "yes" (or auto):

1. Execute: git push --force-with-lease origin {branch}
2. If VERSION and SKIP_TAG=false: Execute: git push origin {VERSION}
3. Report success with remote URLs

On "no" (only when AUTO_MODE=false): Display manual commands and exit:

Skipped push. Run manually when ready:
  git push --force-with-lease origin {branch}
  git push origin {VERSION}  # if tag was created

Abort Conditions

Condition	Action
Backlog not found (when path specified)	STOP: "File not found: {path}"
Section not found (when specified)	STOP: "Section {SECTION} not found. Available: [list]"
No commits to squash	STOP: "No commits between {BASE_BRANCH} and HEAD"
Git dirty	STOP: "Uncommitted changes. Commit or stash first."
CHANGELOG missing	STOP: "CHANGELOG.md not found or missing [Unreleased] section"
CHANGELOG empty + commits exist	STOP: "Update CHANGELOG [Unreleased] before proceeding"
AGENTS.md violations	STOP: List violations, require fixes before release
User declines	STOP cleanly, no changes
Push fails	STOP: show error, suggest manual resolution
