Refit a Workflow

You are refitting (upgrading) an existing workflow to match the current Spacedock version. This covers scaffolding files (README, mods) and, when schema changes require it, migrating entity frontmatter data. Agent files and the status viewer are shipped with the Spacedock plugin and do not need local updates.

Follow these five phases in order. Do not skip or combine phases.

Phase 1: Discovery

Step 1 — Identify the workflow

The user must provide a workflow directory path. If they didn't, ask:

Which workflow directory should I refit?

Store the confirmed path as {dir}. Resolve it to an absolute path. Also derive {project_root} (git root or cwd) and {dir_basename} (last path component).

Step 2 — Read current scaffolding and extract version stamps

Read each scaffolding file and extract its version stamp:

1. README — Read {dir}/README.md. Extract version from YAML frontmatter commissioned-by: spacedock@X.Y.Z. Store as {readme_version}.
2. Mod files — Scan {dir}/_mods/*.md for installed mods. For each, read the version frontmatter field. Match against canonical mods at {project_root}/mods/{name}.md by filename. Store the local version and canonical version for each. Also scan {project_root}/mods/*.md for mods not yet installed.
3. Legacy status script — If {dir}/status exists, note it for cleanup (status now ships with the plugin).

If a file doesn't exist, note it as missing and skip it.

Step 3 — Read current Spacedock version

Read .codex-plugin/plugin.json from the Spacedock plugin directory (the directory containing the skills/ folder — resolve from your own plugin context). The .claude-plugin/plugin.json mirror carries the same version for the Claude host. Extract the version field and store it as {current_version}.

Step 4 — Evaluate

• If all version stamps match {current_version}: report "Workflow is already up to date." and stop.
• If no stamps were found on any versioned file (README): enter Degraded Mode (see below).
• Otherwise: proceed to Phase 2 with the list of outdated files.

Phase 2: Classify Files by Upgrade Strategy

Each scaffolding file gets a specific upgrade strategy based on how safe it is to auto-replace:

Present the classification to the captain:

Upgrade plan:

File	Current State	Strategy
status	{status_version or "no stamp"}	Replace
README.md	{readme_version or "no stamp"}	Show diff (manual review)
_mods/{name}.md (for each)	{local_version vs canonical_version / custom mod}	Version diff

Proceed with this upgrade plan? (y/n)

For mods, include all files found in _mods/.

Wait for the captain to confirm before proceeding.

Phase 3: Execute Upgrades

Extract workflow-specific values from README

Before generating any files, read {dir}/README.md and extract:

1. Mission — from the # {title} heading (first H1).
2. Stages — from the ## Stages section. Each ### \{stage_name}`` subsection is a stage, in order. For each stage, extract:
   • Stage name
   • Inputs, Outputs, Good, Bad descriptions
   • Whether "Human approval: Yes" appears (indicates an approval gate for the transition INTO this stage)
3. Schema fields — from the ## Schema section's YAML block.
4. Entity description — from the first paragraph after the H1.

3a. Legacy Status Script (Remove)

If {dir}/status exists, it's a legacy workflow-local status script. The status viewer now ships as the spacedock status launcher command.

1. Inform the captain: "The status viewer is now the spacedock status launcher command. Removing the workflow-local {dir}/status script."
2. git rm {dir}/status

3b. README (Show Diff)

1. Re-select the matching template for this workflow's shape (development / experiment / refinement) and generate its FULL body for this workflow, substituting the extracted values (mission, stages, schema). Regenerate the workflow-INDEPENDENT sections too — ## Workflow-specific rules, the proof/triage bullets, and the ## {Entity} Template / Verified by example — not only the stage prose. These carry the accumulated scaffolding content; a refit that re-renders only the stage values propagates the version stamp but not the content the template gained since this workflow was commissioned.
2. Diff it against the user's current README.
3. Present the diff to the captain, noting which differences are likely template changes vs user customizations:

README template diff:

The following differences exist between your README and what the current template would generate. Differences may be template improvements or your intentional customizations.

{diff output}

I have NOT modified your README. Review the diff and apply any changes you want manually, or tell me which specific changes to make.

Additive sections the current template gained since your workflow was commissioned (new proof/triage bullets, a fixed example) appear as additions in this diff — those are the accumulated scaffolding content, safe to adopt; hunks that touch your customized stage prose are yours to judge.

Do NOT auto-modify the README. The captain decides what to adopt.

3c. Mods (Version diff)

For each mod file in {dir}/_mods/*.md:

1. Match against canonical — Check if {project_root}/mods/{name}.md exists (matching by filename).

2. If canonical exists — Compare the version frontmatter field in the local file against the canonical file.

   • If versions match: report "up to date" and skip.
   • If versions differ: show a diff between the local and canonical files. Ask the captain:

Mod update: {name} (local: {local_version} → canonical: {canonical_version}) {diff output}

Update this mod? (y/n)

3. If no canonical match — The mod is custom (user-authored or third-party). Acknowledge neutrally:

Found custom mod: {name} — {description from frontmatter}. No canonical version to compare against. No action needed.

4. New mods available — For each canonical mod in {project_root}/mods/*.md not present in {dir}/_mods/, offer to install:

New mod available: {name} — {description from frontmatter}. Install it? (y/n)

If accepted, copy the canonical file to {dir}/_mods/{name}.md. Create _mods/ if it doesn't exist.

3d. Legacy Migration (pr-lieutenant → pr-merge mod)

If {project_root}/.claude/agents/pr-lieutenant.md exists and {dir}/_mods/pr-merge.md does not, offer migration:

Migration: pr-lieutenant → pr-merge mod

Your workflow uses a pr-lieutenant agent for PR management. Spacedock now uses mods instead. I'll:

1. Create {dir}/_mods/pr-merge.md with the PR management mod
2. Remove agent: pr-lieutenant from any README stage entries
3. Regenerate the first-officer with mod discovery

The pr-lieutenant agent file at .claude/agents/pr-lieutenant.md will be left in place. You can delete it manually if no longer needed.

Proceed with pr-lieutenant migration? (y/n)

If accepted:

1. Copy {project_root}/mods/pr-merge.md to {dir}/_mods/pr-merge.md
2. Edit the README frontmatter: remove agent: pr-lieutenant from any stage entries

Phase 4: Migrate Entity Data

After upgrading scaffolding, check whether schema changes require migrating existing entity data.

ID Style Preservation

README frontmatter may contain id-style: sequential, id-style: sd-b32, or id-style: slug. Refit must preserve the current id-style; do not silently change it. Report the current style in the refit summary, recommend sd-b32 only when collaboration pressure exists (worktree stages, PR/merge mods, multiple creators, branches, or offline work), and require explicit captain approval before changing README frontmatter.

Before any approved style change, run status --validate against the workflow and report failures. Existing sequential workflows require no data rewrite. SD-B32 means Spacedock Base32: this style requires each entity to store a 24-character lowercase SD-B32 stored ID derived from SHA-256 digest material and formatted with Spacedock's alphabet 0123456789abcdefghjkmnpqrstvwxyz, while status displays shortest unique prefixes. Slug style derives identity from filenames and makes status --next-id non-applicable. Migration is manual migration in this release: use validation to make the change safe, and defer rewrite automation or bulk frontmatter rewriting to a separate tracked task.

Step 1 — Detect schema changes

Compare the old README's ## Schema and ### Field Reference sections against the new version. Look for:

• Changed field types or ranges (e.g., score changed from integer/25 to float/0.0–1.0)
• Renamed fields (e.g., priority → score)
• Removed fields (fields in entities that are no longer in the schema)
• New required fields (fields added to the schema that existing entities lack)

If no schema changes affect entity data, skip to Phase 5.

Step 2 — Scan entities

For each detected schema change, scan all entity files in {dir}/*.md (excluding README.md) and identify which entities have values in the affected fields.

Present findings to the captain:

Schema migration needed:

{description of what changed in the schema}

Affected entities: {list of entities with current values that need migration}

Proposed migration: {what the migration would do — e.g., "Convert score from /25 to 0.0–1.0 by dividing by 25"}

Apply this migration? (y/n)

Step 3 — Execute migration

On the captain's approval, update the affected entity frontmatter fields. Use the Edit tool — never rewrite whole entity files. Only touch the specific fields identified in the migration plan.

Show a summary of what was migrated:

Migrated {N} entities: {list of entity: old_value → new_value}

Phase 5: Finalize

1. Update version stamp to {current_version} in the README YAML frontmatter: commissioned-by: spacedock@{current_version}.
2. Show a summary:

Refit complete:

File	Action
status	{Removed (legacy) / Not present}
_mods/{name}.md (for each)	{Updated / Already current / Installed / Custom (no action)}
README.md	{Stamp updated / User-reviewed / No changes}

Suggest committing:

git commit -m "refit: upgrade workflow scaffolding to spacedock@{current_version}"

Degraded Mode (No Version Stamp)

When no version stamps are found on the README, the original baseline cannot be determined. Inform the captain and offer two options:

No version stamps found. This workflow was commissioned before version stamping was implemented, or the stamps were removed. I can't determine what the original scaffolding looked like.

Two options:

1. Stamp only — Add version stamps to existing files without changing anything else. This establishes a baseline for future refits.
2. Full refit with review — Generate what the current templates would produce and show a full diff for every scaffolding file. You review and approve each change.

Which option?

Option 1: Stamp Only

Add version stamps to versioned files without modifying anything else:

• README.md — Add YAML frontmatter with commissioned-by: spacedock@{current_version} (wrap in --- delimiters if frontmatter doesn't exist).
• status — Insert # commissioned-by: spacedock@{current_version} as the second line (after #!/bin/bash).

Option 2: Full Refit with Review

Execute Phase 3, but show a full diff for every file (including status) and require the captain's explicit approval before replacing each one. Never auto-replace files without a version stamp — the risk of overwriting customizations is too high.

Safety Rules

• Never modify entity file bodies — only frontmatter, and only during an approved schema migration.
• Never auto-replace without a version stamp — always enter degraded mode.
• Always show diffs — even for "replace" strategy files, show the diff before replacing.
• Git is the safety net — remind the captain they can git diff or git checkout to recover.
