Release Management

The project uses a minimalistic changeset-based release system inspired by @changesets/cli.

Commands

version (Preview Only)

The version command operates in preview mode and never modifies files:

node scripts/changeset.js version
# Or
make version

This command:

• Reads all changeset files from .changeset/ directory
• Determines the appropriate version bump (major > minor > patch)
• Shows a preview of the CHANGELOG entry
• Never modifies any files

release [type] [--yes|-y]

The release command creates an actual release:

node scripts/changeset.js release
# Or (recommended - runs tests first)
make release

This command:

• Checks prerequisites (clean tree, main branch)
• Updates CHANGELOG.md with new version and changes
• Deletes processed changeset files (if any exist)
• Automatically commits the changes
• Creates and pushes a git tag for the release

Flags:

• --yes or -y: Skip confirmation prompt

Release Workflow

graph TD
    A[Add changeset files] --> B[Preview with version command]
    B --> C{Changes look good?}
    C -->|No| D[Modify changesets]
    D --> B
    C -->|Yes| E[Run release command]
    E --> F[Update CHANGELOG.md]
    F --> G[Delete changeset files]
    G --> H[Commit changes]
    H --> I[Create git tag]
    I --> J[Push tag to remote]

Changeset File Format

Changeset files are markdown files in .changeset/ directory with YAML frontmatter:

"gh-aw": patch

Brief description of the change

Bump types:

• patch - Bug fixes and minor changes (0.0.x)
• minor - New features, backward compatible (0.x.0)
• major - Breaking changes (x.0.0)

Prerequisites for Release

When running release, the script checks:

• Clean working tree: All changes must be committed or stashed
• On main branch: Must be on the main branch to create a release

Releasing Without Changesets

For maintenance releases with dependency updates:

# Defaults to patch release
node scripts/changeset.js release

# Or specify release type explicitly
node scripts/changeset.js release minor

# Skip confirmation
node scripts/changeset.js release --yes

The script will:

• Default to patch release if no type specified
• Add a generic "Maintenance release" entry to CHANGELOG.md
• Commit the changes
• Create a git tag
• Push the tag to remote

Firewall Log Parsing

The firewall log parser provides analysis of network traffic logs from agentic workflow runs.

Log Format

Firewall logs use space-separated format with 10 fields:

timestamp client_ip:port domain dest_ip:port proto method status decision url user_agent

Example:

1761332530.474 172.30.0.20:35288 api.enterprise.githubcopilot.com:443 140.82.112.22:443 1.1 CONNECT 200 TCP_TUNNEL:HIER_DIRECT api.enterprise.githubcopilot.com:443 "-"

Field Descriptions

• timestamp - Unix timestamp with decimal (e.g., "1761332530.474")
• client_ip:port - Client IP and port or "-"
• domain - Target domain:port or "-"
• dest_ip:port - Destination IP and port or "-"
• proto - Protocol version (e.g., "1.1") or "-"
• method - HTTP method (e.g., "CONNECT", "GET") or "-"
• status - HTTP status code (e.g., "200", "403") or "0"
• decision - Proxy decision (e.g., "TCP_TUNNEL:HIER_DIRECT") or "-"
• url - Request URL or "-"

10. user_agent - User agent string (quoted) or "-"

Request Classification

    E -->|Contains TCP_TUNNEL, TCP_HIT, TCP_MISS| C
    E -->|Contains NONE_NONE, TCP_DENIED| D
    E -->|Other| F[Denied by default]

Allowed Indicators:

• Status codes: 200, 206, 304
• Decisions containing: TCP_TUNNEL, TCP_HIT, TCP_MISS

Denied Indicators:

• Status codes: 403, 407
• Decisions containing: NONE_NONE, TCP_DENIED

Default: Denied (for safety when classification is ambiguous)

Integration Points

The logs and audit commands automatically:

• Search for firewall logs in run directories
• Parse all .log files in firewall-logs/ or squid-logs/ directories
• Aggregate statistics across all log files
• Include firewall analysis in console and JSON output
• Cache results in run_summary.json

Implementation

Files:

• pkg/cli/firewall_log.go (396 lines) - Core parser implementation
• pkg/cli/firewall_log_test.go (437 lines) - Unit tests
• pkg/cli/firewall_log_integration_test.go (238 lines) - Integration tests

Testing:

# Unit tests
make test-unit

# Integration tests
go test ./pkg/cli -run TestFirewallLogIntegration

Breaking CLI Rules

This section defines what constitutes a breaking change for the gh-aw CLI. These rules help maintainers and contributors evaluate changes during code review and ensure stability for users.

Overview

Breaking changes require special attention during development and review because they can disrupt existing user workflows. This section provides clear criteria for identifying breaking changes and guidance on how to handle them.

Categories of Changes

Breaking Changes (Major Version Bump)

The following changes are always breaking and require:

• A major changeset type
• Documentation in CHANGELOG.md with migration guidance
• Review by maintainers

1. Command Removal or Renaming

Breaking:

• Removing a command entirely (e.g., removing gh aw logs)
• Renaming a command without an alias (e.g., gh aw compile → gh aw build)
• Removing a subcommand (e.g., removing gh aw mcp inspect)

Examples from past releases:

• Removing --no-instructions flag from compile command (v0.17.0)

2. Flag Removal or Renaming

Breaking:

• Removing a flag (e.g., removing --strict flag)
• Changing a flag name without backward compatibility (e.g., --output → --out)
• Changing a flag's short form (e.g., -o → -f)
• Changing a required flag to have no default when it previously had one

Examples from past releases:

• Remove GITHUB_TOKEN fallback for Copilot operations (v0.24.0)

3. Output Format Changes

Breaking:

• Changing the structure of JSON output (removing fields, renaming fields)
• Changing the order of columns in table output that users might parse positionally
• Changing exit codes for specific scenarios
• Removing output fields that scripts may depend on

Examples from past releases:

• Update status command JSON output structure (v0.21.0): replaced agent with engine_id, removed frontmatter and prompt fields

4. Behavior Changes

Breaking:

• Changing default values for flags (e.g., strict: false → strict: true)
• Changing authentication requirements
• Changing permission requirements
• Changing the semantics of existing options

Examples from past releases:

• Change strict mode default from false to true (v0.31.0)
• Remove per-tool Squid proxy - unify network filtering (v0.25.0)

5. Schema Changes

Breaking:

• Removing fields from workflow frontmatter schema
• Making optional fields required
• Changing the type of a field (e.g., string → object)
• Removing allowed values from enums

Examples from past releases:

• Remove "defaults" section from main JSON schema (v0.24.0)
• Remove deprecated "claude" top-level field (v0.24.0)

Non-Breaking Changes (Minor or Patch Version Bump)

The following changes are not breaking and typically require:

• A minor changeset for new features
• A patch changeset for bug fixes

1. Additions

Not Breaking:

• Adding new commands
• Adding new flags with reasonable defaults
• Adding new fields to JSON output
• Adding new optional fields to schema
• Adding new allowed values to enums
• Adding new exit codes for new scenarios

Examples:

• Add --json flag to status command (v0.20.0)
• Add mcp-server command (v0.17.0)

2. Deprecations

Not Breaking (when handled correctly):

• Deprecating commands (with warning, keeping functionality)
• Deprecating flags (with warning, keeping functionality)
• Deprecating schema fields (with warning, keeping functionality)

Requirements for deprecation:

• Print deprecation warning to stderr
• Document the deprecation and migration path
• Keep deprecated functionality working for at least one minor release
• Schedule removal in a future major version

3. Bug Fixes

Not Breaking (when fixing unintended behavior):

• Fixing incorrect output
• Fixing incorrect exit codes
• Fixing schema validation that was too permissive

Note: Fixing a bug that users depend on may require a breaking change notice.

4. Performance Improvements

Not Breaking:

• Faster execution
• Reduced memory usage
• Parallel processing optimizations

5. Documentation Changes

Not Breaking:

• Improving help text
• Adding examples
• Clarifying error messages

Guidelines for Contributors

When Making CLI Changes:

• Check the decision tree before implementing changes
• Document breaking changes clearly in the changeset
• Provide migration guidance for users affected by breaking changes
• Consider backward compatibility - can you add an alias instead of renaming?
• Use deprecation warnings for at least one minor release before removal

Changeset Format for Breaking Changes:

"gh-aw": major

Remove deprecated `--old-flag` option

**⚠️ Breaking Change**: The `--old-flag` option has been removed.

**Migration guide:**
- If you used `--old-flag value`, use `--new-flag value` instead
- Scripts using this flag will need to be updated

**Reason**: The option was deprecated in v0.X.0 and has been removed to simplify the CLI.

Changeset Format for Non-Breaking Changes:

For new features:

"gh-aw": minor

Add --json flag to logs command for structured output

For bug fixes:

"gh-aw": patch

Fix incorrect exit code when workflow file not found

Review Checklist for CLI Changes

Reviewers should verify:

• [ ] Breaking change identified correctly - Does this change match any breaking change criteria?
• [ ] Changeset type appropriate - Is it marked as major/minor/patch correctly?
• [ ] Migration guidance provided - For breaking changes, is there clear migration documentation?
• [ ] Deprecation warning added - If deprecating, does it warn users?
• [ ] Backward compatibility considered - Could this be done without breaking compatibility?
• [ ] Tests updated - Do tests cover the changed behavior?
• [ ] Help text updated - Is the CLI help accurate?

Exit Code Standards

The CLI uses standard exit codes:

| Exit Code | Meaning | Breaking to Change |

|-----------|---------|-------------------|

| 0 | Success | No (adding is fine) |

| 1 | General error | No (for new errors) |

| 2 | Invalid usage | No (for new checks) |

Breaking: Changing the exit code for an existing scenario (e.g., changing from 1 to 2 for a specific error type).

JSON Output Standards

When adding or modifying JSON output:

• Never remove fields without a major version bump
• Never rename fields without a major version bump
• Never change field types without a major version bump
• Adding new fields is safe - parsers should ignore unknown fields
• Adding new enum values is safe - parsers should handle unknown values gracefully

Strict Mode and Security Changes

Special consideration for strict mode changes:

• Making strict mode validation refuse instead of warn is breaking (e.g., v0.30.0)
• Changing strict mode defaults is breaking (e.g., v0.31.0)
• Adding new strict mode validations is not breaking (strictness is opt-in initially)

Go Module Summaries

The scratchpad/mods/ directory contains AI-generated summaries of Go module usage patterns in the gh-aw repository, created by the Go Fan workflow.

Purpose

Go module summaries provide:

• Module overview and version information
• Files and APIs that use the module
• Research findings from the module's GitHub repository
• Improvement opportunities (quick wins, feature opportunities, best practices)
• References to documentation and changelog

File Naming Convention

Module summary files follow a consistent naming pattern where the Go module path has slashes replaced with dashes:

| Module Path | File Name |

|-------------|-----------|

| github.com/goccy/go-yaml | goccy-go-yaml.md |

| github.com/spf13/cobra | spf13-cobra.md |

| github.com/stretchr/testify | stretchr-testify.md |

Generation Process

The summaries are generated by the Go Fan workflow:

graph LR
    A[Scheduled Trigger<br/>Weekdays 7 AM UTC] --> B[Load Cache Memory]
    B --> C[Select Next Module<br/>Round-Robin]
    C --> D[Analyze Module Usage]
    D --> E[Research GitHub Repo]
    E --> F[Generate Summary]
    F --> G[Write to scratchpad/mods/]
    G --> H[Update Cache Memory]
    H --> I[Commit & Push]

Update Frequency: Daily on weekdays (Monday-Friday) at 7 AM UTC

Round-Robin Selection: The workflow uses cache-memory to track which module was analyzed last, ensuring each module gets updated in rotation.

Usage Guidelines

When working with Go modules in the codebase:

• Check existing summaries in scratchpad/mods/ for module-specific patterns and best practices
• Reference improvement opportunities when upgrading or refactoring module usage
• Consult API documentation links provided in the summaries for authoritative reference
• Update summaries manually if significant changes are made to module usage patterns (the workflow will refresh on its next run)

Summary Contents

Each module summary includes the following sections:

• Module Overview: Version used and general purpose
• Usage Analysis: Files and code locations using the module
• API Surface: Functions, types, and methods utilized
• Research Findings: Information from the module's repository (recent releases, documentation, best practices)
• Improvement Opportunities: Suggestions for better module usage
• References: Links to documentation, changelog, and GitHub repository
