Agent Skills: Ship Skill

Ship Skill

Automates the full cycle: update documentation -> stage -> commit -> push.

Workflow

Step 1: Review changes

Run all three commands to get the full picture:

git status --short
git diff --cached --name-status
git log @{upstream}..HEAD --oneline 2>/dev/null

Also identify the current branch and remote tracking status:

git branch --show-current
git rev-parse --abbrev-ref @{upstream} 2>/dev/null

Classify uncommitted changes from git status:

• M — modified, ?? — untracked, D — deleted, R — renamed

If the working tree is clean but unpushed commits exist, this is the doc catch-up path:

1. Run git diff @{upstream}..HEAD --name-status to list all files changed in unpushed commits
2. Analyze those files in Step 2 as if they were uncommitted changes
3. Proceed to Step 3 to check for missing documentation updates (CHANGELOG, README, CLAUDE.md, marketplace.json)
4. If documentation updates are needed, make them, commit, and push
5. If no documentation updates are needed, just push

If both the working tree is clean AND no unpushed commits exist, report "nothing to ship" and stop.

Step 2: Analyze what changed

Read every modified/untracked file (or every file from unpushed commits in the doc catch-up path) to understand the nature of the changes.

| Path pattern | Type | | -------------------------------------------- | ---------------------------------------------- | | posts/, articles/, content/ | content/writing | | .claude/skills/ | skill config | | src/, *.go, *.py, *.ts, *.R, *.r | code/scripts | | *.md | documentation | | *.json, *.yaml, *.toml, *.csv | config/data | | Resources/, resources/ | resource list | | *.ipynb | notebook | | .r2-upload-map/ | resource mapping (commit with related content) |

Step 3: Update documentation

For each applicable documentation file, read the current contents first, then update.

CHANGELOG.md

• When: Always, if the file exists in the repo root
• Format: Follow Keep a Changelog
• Add a new ## [YYYY-MM-DD] section (today's date) at the top of the log
• If today's date section already exists, append to it instead of creating a duplicate
• Subsections: Added, Changed, Removed, Fixed — only include relevant ones
• Each entry: one concise line describing the change from a user/reader perspective

CLAUDE.md (always run)

• When: Always. Read CLAUDE.md and compare against the current project state — not just the changes being shipped, but also decisions made during the session, new or renamed files on disk, and structural changes
• Skip when: Changes are limited to content additions (e.g., adding a link to Resources) AND no session-level decisions or structural changes occurred
• Update only the affected sections — do not rewrite the entire file
• Check for temporal markers (e.g., "Current position," dates, deadlines, status tables) that may be stale given the changes being shipped

README files (root or section-level)

• When: Changes affect content described by that README
• Examples: adding a notebook -> update the directory's README; renaming a section -> update root README
• Skip when: The change is self-evident from the file itself (e.g., adding a row to a resource table — the table IS the README)

Cascade check (skip if no scripts or data files changed)

If any modified files are scripts or data files:

• Identify downstream files: Find all markdown reports, appendices, and documentation that reference outputs or data from the modified files — search for filename references, table headers, variable names, and output patterns
• Verify consistency: Check that numbers, table data, file paths, and cross-references in downstream files match the current state of the modified scripts and their outputs
• Fix discrepancies: Update any stale numbers, outdated references, or mismatched data in downstream files. Include these fixes in the commit

Stale and missing reference check

After identifying all changed, added, and deleted files, check documentation files for stale or missing references:

• Deleted files: Search README.md, CLAUDE.md, and any doc that might reference them (folder trees, file lists, dependency mentions)
• Renamed/moved files: Update all path references
• Removed features or dependencies: Remove or update mentions in all docs
• New directories or files: If CLAUDE.md or README.md contain folder trees, check whether newly added directories or files should appear in those trees
• Run: git diff --name-status to get the full list of added (A/??), deleted (D), and renamed (R) files, then search docs for entries that need adding or removing

Other docs

• If any other documentation file is directly affected by the changes, update it too

Step 4: Decide commit strategy

Examine the changes identified in Step 2 and choose a strategy:

• Single topic -> one commit for all files
• Multiple topics -> group by directory/topic, one commit per group

Grouping priority (highest first):

1. Content directories — one commit per article/document unit (e.g., each notebook directory, each post)
2. Skill directories — one commit per skill (.claude/skills/<name>/)
3. Code changes — merge all code changes into one commit
4. Config / documentation files — merge into one commit

Rules:

• .r2-upload-map/*.json files belong with their related content group, not standalone
• Documentation updates from Step 3 (CHANGELOG, README, etc.) go into the commit of the group that triggered them
• If all changes fall under one group, use a single commit regardless of file count

Step 5: Generate commit messages

Generate one message per commit group from Step 4.

Follow conventional commits:

<type>: <description>

Types: feat, fix, refactor, docs, test, chore, perf, ci

Rules:

• Under 70 characters
• Describe the user-facing change, not the documentation update
• If the only changes are documentation, use docs: type
• If code + docs changed together, use the type that matches the code change

Examples by group type:

• Content: docs: add exploratory analysis notebook
• Skills: chore: update commit skill workflow
• Code: feat: add batch processing to pipeline
• Config: chore: update project config

Step 6: Stage and commit

For each commit group (from Step 4), in grouping-priority order:

git add <group-file1> <group-file2> ...
git commit -m "<group-message>"

Repeat for each group until all changes are committed.

Rules:

• Stage files explicitly — never use git add . or git add -A
• Include the documentation files updated in Step 3 with the commit group that triggered them
• Exclude temp files (*.bak-*, .DS_Store, node_modules/, .claude/)
• .r2-upload-map/*.json files go with their related content commit, not standalone

Step 7: Push

git push

If no upstream is set:

git push -u origin <current-branch>

Step 8: Confirm

Run: git log --oneline -3

Display the commit hash and message to confirm success.
