Pull Request Preparation Workflow

When NOT To Use

Reviewing someone else's PR (use sanctum:pr-review)
Only the commit message is needed (use sanctum:commit-messages)

Usage

Use this skill to stage changes and generate a PR summary. Run Skill(sanctum:git-workspace-review) first to capture the repository state and diffs.

Required Progress Tracking

Create TodoWrite items for these steps before starting:

pr-prep:workspace-reviewed
pr-prep:quality-gates
pr-prep:self-reviewed
pr-prep:changes-summarized
pr-prep:testing-documented
pr-prep:pr-drafted
pr-prep:content-verified

Mark each item as complete as the section is finished.

Step 1: Review Workspace (`workspace-reviewed`)

Confirm that Skill(sanctum:git-workspace-review) is complete. If changes were staged after the initial review, re-execute the skill to refresh the context.

Step 2: Run Quality Gates (`quality-gates`)

Execute formatting, linting, and tests using project-specific commands (e.g., make lint, make test). Resolve all failures before proceeding. If a task cannot be executed locally, document the reason and the alternative validation performed. Language-specific commands and failure handling are detailed in modules/quality-gates.md.

Capabilities Reference Sync

If any plugin files changed (plugin.json, skills, commands, agents, or hooks), run make docs-sync-check to verify book/src/reference/capabilities-reference.md is current. If it reports discrepancies, run /sync-capabilities --fix or update the reference manually before proceeding.

Step 2.5: Self-Review Pass (`self-reviewed`)

Read the diff as if you are a reviewer seeing it for the first time. This catches scope creep, stale debug code, and unclear changes before anyone else spends time on them.

Automated checks:

# Check for debug statements left in
git diff --cached --name-only | xargs grep -nE \
  '(console\.log|print\(|debugger|TODO|FIXME|HACK|XXX)' \
  2>/dev/null || true

# Check for commented-out code blocks (3+ consecutive lines)
git diff --cached | grep -c '^+.*//.*[a-zA-Z]' || true

# Check for formatting-only commits mixed with feature work
git log --oneline $(git merge-base HEAD origin/master)..HEAD | \
  grep -iE '(fmt|format|lint|style|whitespace)' || true

Additive bias audit:

Run Skill(imbue:justify) to compute the additive bias score and check Iron Law compliance. If the score is YELLOW or above, justify each flagged signal before proceeding. If RED or STOP, rethink the approach.

Manual verification:

Read the full diff: does every change serve the stated goal?
No debug statements or TODO markers left in
No commented-out code blocks
No formatting changes mixed with logic changes
No fixup commits that should be squashed
Additive bias score is GREEN or justified YELLOW
Iron Law compliance: PASS (no test tampering)

If issues are found, fix them before proceeding.

Step 3: Summarize Changes (`changes-summarized`)

Use the notes from the workspace review and the output of git diff --stat origin/main...HEAD to understand the scope. Identify key points in the diffs and group them into 2-4 paragraphs highlighting the technical changes and their rationale. Note breaking changes, migrations, or documentation updates.

Step 4: Document Testing (`testing-documented`)

List each test command executed and its result. If tests were skipped, document the reason and the mitigation plan.

Attach a manual test plan when any of these hold:

The change has no automated coverage.
It touches a user-facing or CLI-facing flow.
It is a bug fix. Give reproduce, fix, and verify steps, where the reproduce step fails on the parent commit.
It changes an external contract.

Write it as numbered steps, each stating its expected result. A step without an expected result is a step the reviewer cannot fail. Format and examples are in modules/pr-template.md.

Step 5: Draft the PR (`pr-drafted`)

Populate the template with the facts table (Who, Where, When), then the Why and What-and-how sections, then Test plan and Checklist. Write the title imperative and self-contained so it reads correctly in git log out of context.

All three table rows are filled on every PR. A row that does not apply says so (External: none, on merge) rather than being deleted, so a reader can tell an omitted blast radius from a blast radius of none.

Add issue references, screenshots, migration guides, or follow-up items as the change calls for them. Template structure, worked examples, and size variations are in modules/pr-template.md. The decision behind the structure, with its sources, is recorded in docs/adr/0021-pr-descriptions-in-two-registers.md.

Step 6: Verify Content Quality (`content-verified`)

Apply Skill(scribe:slop-detector) principles to the draft. Verify that the PR description avoids tier-1 slop words (delve, comprehensive, leverage, utilize, robust, seamless) and formulaic phrases like "I'd be happy to" or "It should be noted." Ensure there is no AI attribution in the text and that all claims are grounded with evidence such as commands, numbers, or filenames. Use active voice and maintain a balanced structure with prose for context.

Vocabulary Substitutions

Replace leverage or utilize with use.
Replace comprehensive with thorough or complete.
Replace robust with solid or reliable.
Replace facilitate with help or enable.
Replace streamline with simplify.

Remediation

If the description contains slop, apply Skill(scribe:doc-generator) principles to ground claims with specifics, remove marketing language, and use direct statements.

Output Instructions

Write the final PR description to the specified path, then display the file path and its contents for confirmation.

Notes

Do not include tool or AI attribution in the PR text. If changes are required mid-process, re-run quality gates. This skill covers preparation; pushing changes and opening the PR occurs outside this workflow.

TodoWrite patterns - naming conventions for sanctum TodoWrite items

Troubleshooting

If project-specific commands like make or npm are unavailable, verify the environment setup against the README. For permission errors, check write access to build directories. If a step fails without clear output, retry the command with verbose flags to inspect the logs.

Exit Criteria

All 7 TodoWrite items (pr-prep:workspace-reviewed through pr-prep:content-verified) are marked complete before the skill declares done
Quality gates (formatting, linting, tests) run and pass; any failure is fixed before proceeding, not skipped
PR description file written to the specified path and its contents displayed for confirmation
Facts table present with all three rows (Who, Where, When) filled, including the External: half of Where
Why section grounded in an issue, a number, or an incident rather than a general claim
Manual test plan attached whenever one of the four triggers in Step 4 fires, with an expected result on every step
Additive bias score from imbue:justify is GREEN, or YELLOW with each flagged signal explicitly justified
PR description contains none of the tier-1 slop words (delve, comprehensive, leverage, robust, seamless, etc.)
