exarchos

Save and mutate workflow state — init a workflow, update fields, transition phases, and capture a structured handoff before context exhaustion. Use when the user says 'save progress', 'checkpoint', 'I need to stop', or runs /checkpoint. Writes current workflow phase, task progress, and artifacts to the event store for later resumption. Do NOT use for restoring/reading state after a session break (that is /rehydrate) or for workflow initialization framing handled by ideate/debug/refactor commands.

Review failed Exarchos MCP tool calls from the current session, diagnose root causes, and categorize into code bug, documentation issue, or user error. Use when the user says 'dogfood', 'review failures', 'what went wrong', 'triage errors', or runs /dogfood. Scopes exclusively to Exarchos tools (exarchos_workflow, exarchos_event, exarchos_orchestrate, exarchos_view, exarchos_sync). Do NOT use for debugging application code or non-Exarchos tool failures.

Guided authoring of an architectural invariant catalog entry through a 6-step interview (elicit, locate, weight, enforce, number, commit). Drives the invariants_scaffold and invariants_add orchestrate verbs — the agent supplies judgment and natural-language elicitation; the verbs own schema validation, file writing, and event emission. Defaults to mode: audit; mode: check is an advanced opt-in. Triggers: 'add an invariant', 'author an invariant', 'enforce an architectural rule', or invariants. Do NOT use for: editing workflow state, running a review, or hand-writing YAML (the verbs write it — never emit catalog YAML yourself).

The composed executor that lands a subagent worktree branch onto an integration branch with preflight + recorded recovery point. For a shared integration branch route through `serialize_merge` (the single-writer lease that composes this action); invoke `merge_orchestrate` directly only for a non-integration merge or when you already hold the lease. Triggers: operator (or `next_actions`) surfaces the merge verb via Exarchos MCP. Local git operation — NOT remote PR merging (that is `merge_pr`).

Decompose the unified docs/specs/ artifact into parallelizable tasks — the ## Decomposition section of the same document whose ## Design & Rationale section holds the DR-N source. Triggers: 'plan implementation', 'create tasks from spec', or /plan. Applies the verification ladder: verification depth matches each task's blast radius — static analysis for low-risk tasks, scoped tests plus a kill-probe for medium, the integration suite on top for high-risk surfaces (judged test-after, not test-first ordering). Auto-chained from /ideate, or run directly to author the whole unified spec at thin/standard depth. Do NOT use for brainstorming, debugging, or code review.

Dispatch implementation tasks to agent teammates in git worktrees. Triggers: 'delegate', 'dispatch tasks', 'assign work', or /delegate. Spawns teammates, creates worktrees, monitors progress. Supports --fixes flag. Do NOT use for single-file changes or polish-track refactors.

Post-merge workflow resolution. Verifies PR merge status, backfills synthesis metadata, force-resolves review statuses, transitions to completed, and cleans up worktrees/branches. Use when the user says 'cleanup', 'resolve workflow', 'mark as done', or runs /cleanup. Do NOT use before PRs are merged.

Interactively prune stale non-terminal workflows from the pipeline. Use when the user says 'prune workflows', 'clean stale workflows', 'pipeline cleanup', or runs /prune. Runs a dry-run preview, displays candidates with staleness and safeguard skips, prompts the user to proceed/abort/force, then bulk-cancels approved workflows with a workflow.pruned audit event. Safeguards skip workflows with open PRs or recent commits unless force is set.

Restore and read workflow state after a context break — re-inject workflow phase, task progress, and behavioral guidance into the current session, reconcile state against git reality, and verify whether a workflow exists. Use when the user says 'resume', 'rehydrate', 'where were we', or runs /rehydrate, or when the agent has drifted after context compaction. Do NOT use for saving or mutating state (that is /checkpoint).

Shepherd PRs through CI and reviews to merge readiness. Operates as an iteration loop within the synthesize phase (not a separate HSM phase). Uses assess_stack to check PR health, fix failures, and request approval. Triggers: 'shepherd', 'tend PRs', 'check CI', or /shepherd.

Collaborative design exploration that authors the Design & Rationale section of the one unified docs/specs/ spec. Triggers: 'brainstorm', 'ideate', 'explore options', or /ideate. Default is a one-pass design preamble; the deep rung gates the 2-3 approach divergent loop and the discover bridge. Do NOT use for task decomposition (that is /plan, which adds Decomposition to the same doc) or code review.

Code improvement workflow with polish and overhaul tracks. Triggers: 'refactor', 'clean up', 'restructure', 'reorganize', or /refactor. Phases: explore, brief, implement, validate. Existing code only — Do NOT use for bug fixes (/debug) or new features (/ideate).

Bug investigation and fix workflow. Triggers: 'debug', 'fix bug', 'investigate issue', 'something is broken', or /debug. Hotfix track for quick fixes, thorough track for root cause analysis. Do NOT use for feature development or refactoring. Do NOT escalate to /ideate unless the fix requires architectural redesign.

Research and discovery workflow for document deliverables — competitive analyses, architecture comparisons, ADR scaffolding, literature reviews, vendor evaluations. No TDD requirement. Phases: gathering → synthesizing → completed. Triggers: 'discover', 'research', 'explore topic', or discover.

Git worktree management for parallel agent team development. Triggers: 'create worktree', 'worktree setup', or during /delegate dispatch. Do NOT use for branch creation without delegation context.

Verification-ladder R5 review dimension: the mutation-adequacy adequacy backstop. Runs the diff-scoped mutation gate, reads the carrier, and turns surviving / NoCoverage mutants into concrete 'write a test that kills <file>:<line>' follow-ups. Triggers: 'mutation adequacy', 'check mutation score', or /review on a HIGH-tier feature. Advisory by default — never blocks merge unless an explicit config override raises severity. Do NOT run full-tree mutation here (scope:'full' is deferred to R10/v2.12).

Lightweight workflow for straightforward changes — plan → implement → optional PR. Direct-commit by default; synthesize is opt-in via synthesisPolicy or a runtime request_synthesize event. Use for trivial fixes, config tweaks, single-file changes, or exploratory work that doesn't warrant subagent dispatch or two-stage review. Triggers: 'oneshot', 'quick fix', 'small change', or oneshot.

Single adversarial review pass over the integrated branch diff — spec-compliance, code quality, and test adequacy judged together by one fresh-context reviewer. Triggers: /review, 'review the changes', or after delegation completes. Emits one verdict (reviews.review.status). Do NOT use for plan-review (that is its own dispatched gate) or for debugging.

Create pull request from completed feature branch using GitHub-native stacked PRs. Use when the user says 'create PR', 'submit for review', 'synthesize', or runs /synthesize. Validates branch readiness, creates PR with structured description, and manages merge queue. Do NOT use before review phase completes. Not for draft PRs.
