/workspace -- Multi-Repo Campaign Coordinator

When to Use

Adding infrastructure that spans repos (new database, shared service, API contract)
Coordinating changes across a frontend repo, backend repo, and infra repo
Breaking a monolith into services (each service becomes a repo-scoped campaign)
Any task where changes in repo A depend on or inform changes in repo B

Do not use when:

All work is in one repo (use /fleet or /archon)
The repos are truly independent with no shared contracts (just run separate campaigns)

Protocol

Step 1: ORIENT

Check for existing workspace session: .planning/workspace/session-{slug}.md — resume if status: active or needs-continue
If starting fresh: identify repos, verify each path is a git repo, read each repo's CLAUDE.md, check .planning/campaigns/ for active campaigns (avoid collisions)

Load prior session context and start watcher:

node .citadel/scripts/momentum-watch-start.cjs
node .citadel/scripts/momentum-read.cjs

Skip momentum injection if output is empty.

Step 2: DECOMPOSE

Rules: items with no deps → Wave 1; dependents → Wave 2+. Max 3 repo-campaigns per wave. Scope format: {repo}:{path}.

For each inter-wave dependency, specify the cross-repo contract: what the producer will produce, what the consumer expects, and where the contract lives (shared types package, OpenAPI spec, env var).

Step 3: WORKSPACE SESSION FILE

Create .planning/workspace/session-{slug}.md with frontmatter: version, id, status: active, started, completed_at: null, direction, repos (path + name + branch per repo), wave_count, current_wave: 1, campaigns_total, campaigns_complete: 0.

Body sections: Direction, Repos table (name/path/branch/status), Work Queue (table from Step 2), Cross-Repo Contracts (producer/consumer/contract/location), Wave Execution Log (per wave: status, campaigns, started, completed), Shared Context (discovery relay accumulation).

Step 4: WAVE EXECUTION

For each wave:

4a. Pre-flight

Verify all dependency campaigns from prior waves completed successfully
Check cross-repo contracts: did producer repos create the expected outputs?
If a dependency failed: park the dependent campaign, flag for user decision

4b. Spawn campaigns

For each repo-campaign in this wave:

Create branch: git checkout -b workspace/{slug}/{repo-name}
Spawn agent with direction: /archon for complex (3+ phases), /fleet if parallelizable, /marshal or direct skill for simple (1-2 steps)
Inject context: discovery briefs from prior waves, prior session context (re-read momentum.json via node .citadel/scripts/momentum-read.cjs, inject as === PRIOR SESSION CONTEXT ===, skip if empty), cross-repo contracts, relevant CLAUDE.md sections from other repos

4c. Collect results

Extract HANDOFF blocks, compress into cross-repo discovery brief, write persistent discovery records:

node .citadel/scripts/discovery-write.cjs \
  --session {session-slug} --agent {repo-name}-{campaign-type} \
  --wave {wave-number} --status {success|partial|failed} \
  --scope "{repo-name}:{scope-path}" --handoff "{json-array}" \
  --decisions "{json-array}" --files "{json-array}" --failures "{json-array}"

4d. Discovery relay

Write workspace/briefs/wave{N}-{repo-name}.md for each completed campaign. Also write workspace/briefs/wave{N}-cross-repo.md summarizing:

New API endpoints or types created
Config changes that affect other repos
Contract fulfillment status (did the producer deliver what was promised?)

4e. Contract verification

For each cross-repo contract: verify the producer created the expected output (file + export for types, route existence for endpoints). If verification fails, flag and do not proceed with consumers.

4f. Update session

Mark completed campaigns, update wave status, write discovery relay, advance current_wave.

Step 5: COMPLETION

Run typecheck/build for each repo in isolation (build shared types package first if present)
Set session status: completed, completed_at: {ISO timestamp}
Run node .citadel/scripts/momentum-synthesize.cjs
List all branches created across repos with suggested merge order based on dependency graph
Output HANDOFF

Fringe Cases

Repo not a git repo: Skip it. Report which repos were skipped and why.
Repo has uncommitted changes: Stash before branching. Record stash ref in session file. Pop on completion or failure.
Active campaign in target repo: Do not start a second campaign. Report the conflict and ask the user whether to wait, park the existing campaign, or merge scopes.
.planning/workspace/ does not exist: Create it (and workspace/briefs/).
Cross-repo contract broken: Park all downstream campaigns. Report which contract failed, which producer was responsible, and what the consumer expected. Do not attempt to fix the producer -- surface the issue for the user or re-run the producer campaign.
One repo fails, others succeed: Mark the failed repo-campaign. Do not roll back successful repos. The user decides whether to fix-and-continue or abandon.
Repos on different machines or remotes: Not supported. All repos must be locally accessible. If a repo is remote-only, the user must clone it first.
Monorepo with multiple packages: Treat each package as a "repo" for scoping purposes. Use {monorepo}:{package-path} as the scope identifier.

Contextual Gates

Disclosure: "Running multi-repo campaign across [repos]. Changes committed to each repo independently." Reversibility: red — coordinates changes across multiple repositories; cross-repo commits are hard to revert in bulk. Trust gates:

Familiar (5+ sessions): coordinates multi-repo campaigns autonomously; novices should use /marshal per repo.

Quality Gates

All repos verified as accessible git repositories before starting
Work queue has no scope overlaps within the same repo
Cross-repo contracts specified for every inter-wave dependency
Discovery relay written after each wave
Contract verification run before spawning consumer campaigns
Each repo's typecheck/build passes independently after completion
Session file updated after every wave (not just at the end)
No campaigns left in active state on completion
