Release Manager

The agent automates release management by parsing conventional commits into structured changelogs, determining semantic version bumps, and assessing release readiness with checklists, rollback runbooks, and stakeholder communication plans.

Quick Start

# Generate changelog from conventional commits
git log --oneline v1.0.0..HEAD | python changelog_generator.py --version 1.1.0 --format both

# Determine version bump from commit history
git log --oneline v1.0.0..HEAD | python version_bumper.py --current-version 1.0.0 --analysis

# Assess release readiness
python release_planner.py --input release-plan.json --include-checklist --include-rollback

Core Workflows

Workflow 1: Generate Changelog and Version Bump

Collect commits since last tag:
```
git log --oneline v1.0.0..HEAD
```
Pipe to
```
changelog_generator.py
```
to produce a Keep-a-Changelog-format CHANGELOG
Pipe to
```
version_bumper.py
```
to determine MAJOR/MINOR/PATCH bump from commit types
Review changelog grouping (Added, Fixed, Changed, Breaking Changes)
Validation checkpoint: All
```
feat
```
commits appear under Added; all
```
fix
```
under Fixed; breaking changes highlighted

git log --oneline v1.2.0..HEAD | python changelog_generator.py \
  --version 1.3.0 --date 2026-03-21 --base-url https://github.com/org/repo --summary

Workflow 2: Assess Release Readiness

Prepare release plan JSON with features, quality gates, stakeholders, and target date
Run
```
release_planner.py
```
with checklist, communication, and rollback flags
Review blocking issues and readiness score
Address blockers (missing approvals, failed gates, overdue items)
Validation checkpoint: Readiness score >80%; zero blocking issues; rollback runbook generated with time estimates

python release_planner.py --input release-plan.json \
  --output-format json --include-checklist --include-communication --include-rollback

Workflow 3: Hotfix Release

Create hotfix branch from last stable tag
Apply minimal fix and run
```
version_bumper.py
```
with
```
--prerelease rc
```
Generate changelog entry for the fix
Assess readiness with expedited checklist
Validation checkpoint: Fix addresses root cause only; rollback procedure tested; stakeholders notified

Version Bump Rules

Commit Type	Bump	Example
`BREAKING CHANGE` or `!` suffix	MAJOR	`feat!: remove deprecated API`
`feat`	MINOR	`feat(auth): add OAuth2`
`fix` , `perf` , `security`	PATCH	`fix(api): resolve race condition`
`docs` , `test` , `chore` , `ci`	None	`docs: update README`

Pre-release progression:

alpha.N

beta.1

rc.1

-> stable release.

Rollback Triggers

Error rate: >2x baseline within 30 minutes
Latency: >50% P95 increase
Feature failures: Core functionality broken
Security incident: Vulnerability exploited
Data corruption: Database integrity compromised

Anti-Patterns

Monolithic releases -- large, infrequent releases with high blast radius; prefer small, frequent releases
Manual deployments -- error-prone and inconsistent; automate every step that can be automated
No rollback plan -- every release must have a tested rollback procedure before going live
Skipping quality gates -- deploying without test coverage, security scan, or dependency audit
Last-minute changes -- code freeze exists for a reason; changes after freeze need explicit approval
Non-conventional commits -- free-form commit messages break changelog generation and version bumping
Environment drift -- staging must mirror production; drift causes false confidence in testing

Troubleshooting

Problem	Cause	Solution
Changelog generator produces empty output	Non-conventional commit messages that don't match the `type(scope): description` pattern	Ensure all commits follow conventional commit format; non-matching messages default to `chore` type which is excluded from user-facing changelogs
Version bumper recommends `none` despite meaningful commits	Commits use types in the ignore list ( `test` , `ci` , `build` , `chore` , `docs` , `style` )	Use `feat` for new features and `fix` for bug fixes; override with `--custom-rules` to map additional types to bump levels
Release planner reports `blocked` status unexpectedly	Missing required approvals ( `pm_approved` , `qa_approved` ) on features or failed required quality gates	Review the `blocking_issues` array in the assessment output; ensure all features have the necessary approval flags set to `true` in the input JSON
Pre-release version not incrementing correctly	Existing pre-release type does not match the requested `--prerelease` type, causing a reset to `.1`	When promoting from alpha to beta or beta to rc, the counter resets to 1 by design; to stay on the same track, pass the same pre-release type
Git log parsing misses commits	Input uses full `git log` format but lines are not properly indented with 4 spaces	Use `git log --oneline` for the simplest input format, or ensure the full format output preserves the standard 4-space commit message indent
Readiness score seems too low	Quality gates default to `pending` status when not explicitly set, and pending gates score zero points	Provide explicit `quality_gates` with accurate `status` values in the release plan JSON, or complete the gates before running assessment
Rollback time estimate is inaccurate	Default rollback steps use generic time estimates that don't reflect your infrastructure	Supply custom `rollback_steps` in the release plan JSON with `estimated_time` values that match your actual deployment environment

Success Criteria

Changelog accuracy: 100% of conventional commits are correctly categorized (feat to Added, fix to Fixed, etc.) with zero miscategorized entries
Version bump correctness: Recommended version matches SemVer rules in all cases -- breaking changes produce MAJOR, features produce MINOR, fixes produce PATCH
Readiness assessment coverage: All blocking issues (missing approvals, failed quality gates, overdue timelines) are surfaced with zero false negatives
Release cycle time reduction: Teams using the planner reduce release preparation time by 40% or more compared to manual checklist tracking
Rollback preparedness: Every release assessed by the planner has a complete, actionable rollback runbook with time estimates and verification steps
Stakeholder communication: Communication plans cover all identified stakeholders with appropriate timing (T-48h external, T-24h internal, T+1h post-deploy)
Tool integration time: New teams can configure and run all three scripts against their repository within 30 minutes of initial setup

Scope & Limitations

This skill covers:

Parsing conventional commits and generating structured changelogs in Markdown and JSON formats
Determining semantic version bumps (major/minor/patch) with pre-release support (alpha, beta, rc)
Assessing release readiness across features, quality gates, approvals, and timelines
Generating rollback runbooks, communication plans, and release checklists from structured input

This skill does NOT cover:

Actual CI/CD pipeline execution or deployment automation (see
```
engineering/ci-cd-pipeline-generator
```
)
Live monitoring, alerting, or incident response during deployments (see
```
engineering/monitoring-alerting-setup
```
)
Code review processes or pull request management (see
```
engineering/code-review-automation
```
)
Infrastructure provisioning, container orchestration, or environment management (see
```
engineering/infrastructure-as-code
```
)

Integration Points

Skill	Integration	Data Flow
`engineering/ci-cd-pipeline-generator`	Embed changelog generation and version bumping as pipeline stages	Git log output flows into `changelog_generator.py` ; version bump output feeds pipeline tagging steps
`engineering/code-review-automation`	Validate that PR commits follow conventional commit format before merge	Commit messages validated upstream ensure clean input for changelog generation
`engineering/monitoring-alerting-setup`	Define rollback triggers based on monitoring thresholds from the rollback runbook	Rollback trigger thresholds (error rate >2x, latency >50%) feed into alert rule configuration
`engineering/api-design-reviewer`	Breaking API changes flagged by the reviewer map to MAJOR version bumps	API review findings populate `breaking_changes` arrays in the release plan JSON
`engineering/infrastructure-as-code`	Deployment steps in the rollback runbook reference infrastructure rollback commands	Rollback runbook `command` fields contain infrastructure-specific commands (kubectl, DNS, load balancer)
`project-management/release-planning`	Release plan JSON structure aligns with PM release tracking artifacts	PM feature lists and approval statuses feed directly into `release_planner.py` input format
