Shipping Methodology

When to use this skill

Use this skill when you need to:

•Run the claudikins-kernel:ship command
•Prepare commit messages and PR descriptions
•Update changelogs and documentation
•Decide merge strategy (squash vs preserve)
•Handle CI failures or merge conflicts
•Validate code integrity before shipping

Core Philosophy

"Ship with confidence, not hope." - Shipping philosophy

Shipping is the final gate. Apply GRFP-style iterative workflow to every stage.

The Five Principles

•Gate check first - claudikins-kernel:verify must have passed. No exceptions.
•Code integrity - Ship exactly what was verified. No sneaky changes.
•GRFP everywhere - Section-by-section approval at every stage.
•Human decides - No auto-merging. Human approves final merge.
•Clean up after - Delete branches, update docs, celebrate.

The Five Stages

Stage 1: Pre-Ship Review

Show what's being shipped. Human confirms ready.

Check	What to Show
Verification status	All phases PASS from claudikins-kernel:verify
Branches to merge	List all execute/task-* branches
Evidence summary	Screenshots, curl responses from catastrophiser
Code delta	Lines added/removed, files changed

Checkpoint:

code

Ready to ship?

Verified: ✓ All checks passed
Branches: 3 branches to merge
Changes: +450 / -120 lines

[Continue] [Back to Verify] [Abort]

Stage 2: Commit Strategy

Draft commit message(s). Human approves.

Decision:

code

How should we commit?

[Squash into single commit] [Preserve commit history]

Squash (recommended for features):

•Single clean commit on main
•Clear feature boundary
•Easier to revert if needed

Preserve (for large multi-part work):

•Keeps granular history
•Better for debugging
•Use for multi-feature batches

Checkpoint:

code

Commit message:

feat(auth): Add authentication middleware

- JWT token validation
- Role-based access control
- Session management

Closes #42

[Accept] [Revise] [Back]

Stage 3: Documentation (git-perfectionist)

Update README, CHANGELOG, version. GRFP-style.

git-perfectionist uses github-readme plugin:

•Deep-dive on current docs
•Identify gaps from changes
•Pen-wielding for updates
•Section-by-section approval

Files to update:

File	What to Update
README.md	Features, usage, installation if changed
CHANGELOG.md	Add entry in Keep a Changelog format
package.json / Cargo.toml / pyproject.toml	Version bump if needed

Checkpoint:

code

Documentation updates:

README.md:
- Added: Authentication section
- Updated: Installation (new deps)

CHANGELOG.md:
- Added: v1.2.0 entry

Version: 1.1.0 → 1.2.0 (minor)

[Accept] [Revise] [Skip]

Stage 4: PR Creation

Draft PR title and body. Section-by-section approval.

PR Title Pattern:

code

feat(scope): Short description

PR Body Structure:

markdown

## Summary

[2-3 bullet points of what changed]

## Changes

[Detailed breakdown]

## Testing

[How it was verified]

## Screenshots

[If applicable]

Checkpoint:

code

PR ready to create:

Title: feat(auth): Add authentication middleware

Body:
## Summary
- Added JWT token validation
- Implemented role-based access control
...

[Create PR] [Revise] [Back]

Stage 5: Final Merge

CI passes. Human approves. Merge and cleanup.

CI Status Check:

code

CI Status: ⏳ Running...

[Wait for CI] [View logs] [Merge anyway]

On CI pass:

code

CI Status: ✓ All checks passed

Ready to merge PR #42 to main?

[Merge] [Request review first] [Cancel]

After merge:

•Delete feature branches (unless --no-delete-branch)
•Update ship-state.json
•Celebrate

Final output:

code

Done! Shipped to main.

PR #42 merged ✓
Branches cleaned up ✓
Version: 1.1.0 → 1.2.0

Nice work!

Rationalizations to Resist

Agents under pressure find excuses. These are all violations:

Excuse	Reality
"Verify passed yesterday, close enough"	Stale verification = no verification. Re-run claudikins-kernel:verify.
"Just a tiny fix after verify, no big deal"	Any change after verify invalidates it. Re-run claudikins-kernel:verify.
"CI is flaky, I'll merge anyway"	Flaky CI hides real failures. Fix or explicitly skip with caveat.
"It's just a typo, skip the PR"	All changes go through PR. No exceptions.
"Both reviewers passed, auto-merge is fine"	Human approves final merge. Always.
"I'll update the changelog later"	Changelog is part of shipping. Do it now.
"Force push is fine, it's my branch"	Never force push to protected branches. Ever.
"Skip docs, nobody reads them"	Docs are part of shipping. GRFP them.
"The gate check is too strict"	The gate exists for a reason. Pass it properly.

All of these mean: Follow the methodology. Shortcuts create incidents.

Red Flags — STOP and Reassess

If you're thinking any of these, you're about to violate the methodology:

•"Let me just push this one change..."
•"Verify is probably still valid"
•"CI will pass next time"
•"I'll do the PR properly next time"
•"Auto-merge saves time"
•"Docs can wait"
•"Force push will fix it"
•"The human already approved something similar"

All of these mean: STOP. Gate check exists. Human decides. Follow the stages.

Gate Check Pattern (CRITICAL)

The ship-init.sh hook enforces the claudikins-kernel:verify gate with code integrity validation.

Required Checks

bash

# 1. Verify state exists
if [ ! -f "$VERIFY_STATE" ]; then
  echo "ERROR: claudikins-kernel:verify has not been run"
  exit 2
fi

# 2. Unlock flag is set
UNLOCK=$(jq -r '.unlock_ship // false' "$VERIFY_STATE")
if [ "$UNLOCK" != "true" ]; then
  echo "ERROR: claudikins-kernel:verify did not pass or was not approved"
  exit 2
fi

Code Integrity (C-5, C-7)

Ensure we ship exactly what was verified:

bash

# C-5: Commit hash validation
VERIFY_COMMIT=$(jq -r '.verified_commit_sha' "$VERIFY_STATE")
CURRENT_COMMIT=$(git rev-parse HEAD)
if [ "$VERIFY_COMMIT" != "$CURRENT_COMMIT" ]; then
  echo "ERROR: Code changed since verification"
  exit 2
fi

# C-7: File manifest validation
VERIFIED_MANIFEST=$(jq -r '.verified_manifest' "$VERIFY_STATE")
CURRENT_MANIFEST=$(sha256sum "$MANIFEST_FILE" | cut -d' ' -f1)
if [ "$VERIFIED_MANIFEST" != "$CURRENT_MANIFEST" ]; then
  echo "ERROR: Source files changed after verification"
  exit 2
fi

If integrity check fails:

code

Code has changed since verification.

Verified commit: abc123
Current commit:  def456

[Re-run claudikins-kernel:verify] [Abort]

CHANGELOG Format

Follow Keep a Changelog format:

markdown

## [Unreleased]

## [1.2.0] - 2026-01-17

### Added

- Authentication middleware with JWT support (#42)

### Changed

- Updated error messages for clarity

### Fixed

- Token refresh race condition (#38)

## [1.1.0] - 2026-01-10

...

See changelog-merge-strategy.md for merging entries.

External Service Failures

GitHub API Failure (E-6, E-7, E-8)

code

PR creation failed.

Error: GitHub API returned 503

Retry 1/3...

Pattern: Max 3 retries with exponential backoff.

If persistent:

code

GitHub API unavailable after 3 retries.

[Try again] [Save as draft PR] [Manual merge]

Save state with pending_merge: true for recovery.

CI Failure

code

CI failed.

Failed checks:
- lint: 2 errors
- test: 1 failure

[View logs] [Fix and retry] [Skip CI] [Abort]

See ci-failure-handling.md for recovery patterns.

Force Push Protection (S-23)

Never force push to protected branches.

bash

# Check if target is protected
PROTECTED_BRANCHES="main master release"
if echo "$PROTECTED_BRANCHES" | grep -q "$TARGET"; then
  if [ "$FORCE" = "true" ]; then
    echo "ERROR: Cannot force push to $TARGET"
    exit 2
  fi
fi

See force-push-protection.md for safeguards.

Breaking Change Detection (S-24)

Detect breaking changes before shipping:

Signal	Indicates
Removed public function	Breaking
Changed function signature	Breaking
Removed config option	Breaking
Changed default behaviour	Potentially breaking

If breaking change detected:

code

Breaking change detected!

- Removed: authenticate() function
- Changed: login() now requires email

This requires a MAJOR version bump.

[Acknowledge and continue] [Abort]

See breaking-change-detection.md for detection patterns.

Anti-Patterns

Don't do these:

•Shipping without claudikins-kernel:verify passing
•Modifying code after verification
•Force pushing to main/master
•Auto-merging without human approval
•Skipping documentation updates
•Ignoring CI failures
•Using vague commit messages ("fix stuff")
•Forgetting to delete feature branches
