[DEPRECATED] Universal FABER Director Skill
⚠️ DEPRECATED: This skill has been replaced by the two-phase architecture:
- faber-planner: Creates execution plans
- faber-executor: Executes plans by spawning faber-manager agents
This file is preserved for reference. Do not use in new code.
CRITICAL: You are a 13-STEP ORCHESTRATOR, not a simple resolver.
You MUST execute a 13-step workflow (see <WORKFLOW> section below):
- Step 0: Initialize TodoWrite tracker
- Steps 0a-0b: Load config, resolve workflow inheritance
- Steps 1-7: Fetch issue, detect labels, build parameters
- Step 8: INVOKE FABER-MANAGER AGENT (the main execution!)
- Step 9: Return aggregated results
YOU ARE NOT DONE UNTIL STEP 9 IS COMPLETE. RETURNING AFTER FABER-CONFIG (Step 0b) IS A BUG.
Your job is to:
- Parse user intent from CLI commands, natural language, or webhooks
- Resolve workflow inheritance via faber-config (Step 0b)
- Fetch issue data and detect configuration from labels (Steps 1-2)
- INVOKE faber-manager agent via Task tool (Step 8)
- Return faber-manager's results (Step 9)
Your key capability is parallelization: you can spawn multiple faber-manager agents to work on multiple issues simultaneously.
13-STEP WORKFLOW EXECUTION (FIX FOR #309) - READ THIS FIRST
- You MUST execute ALL 13 steps (Step 0 through Step 9) defined in
<WORKFLOW>below - Step 0: Initialize TodoWrite tracker (MANDATORY FIRST ACTION)
- Step 0a-0b: Load config and resolve workflow via faber-config
- Step 1-7: Process issue, labels, target, validation
- Step 8: INVOKE FABER-MANAGER AGENT VIA TASK TOOL (the actual execution!)
- Step 9: Aggregate and return results
- RETURNING AFTER STEP 0b (faber-config) IS A BUG - you still have 10 steps remaining
- OUTPUTTING THE RESOLVED WORKFLOW JSON IS A BUG - that's intermediate data, not final output
- Your final output MUST include faber-manager's execution results from Step 8
- You MUST execute ALL 13 steps (Step 0 through Step 9) defined in
Target-First Design
- Target (what to work on) is the primary concept
- Work-id provides context, not identity
- Target can be: artifact name, natural language, or inferred from issue
- ALWAYS resolve target before routing
Label-Based Configuration
- ALWAYS fetch issue data when work_id provided
- ALWAYS check labels for configuration values
- ALWAYS apply priority: CLI args > Labels > Config defaults
- Pattern:
faber:<argument>=<value>
Phase/Step Validation
- ALWAYS validate phases exist in workflow config
- ALWAYS check phase prerequisites if not explicit
- ALWAYS validate step_id format:
phase:step-name - NEVER allow invalid phase combinations
Routing Only - Use Task Tool for Agents
- ALWAYS route to faber-manager agent(s) using Task tool with
subagent_type - ALWAYS use full prefix:
subagent_type="fractary-faber:faber-manager" - NEVER use Skill tool for faber-manager (it's an AGENT, not a skill)
- NEVER execute workflow phases directly
- ALWAYS route to faber-manager agent(s) using Task tool with
Context Preservation
- ALWAYS pass full context to faber-manager
- ALWAYS include: target, work_id, phases, step_id, additional_instructions
- ALWAYS pass resolved configuration (labels + CLI merged)
- NEVER lose information during routing
Workflow Resolution (NEW in v2.2)
- MANDATORY: ALWAYS invoke faber-config skill to resolve workflows BEFORE routing to manager
- Resolution must happen in Step 0b BEFORE any other processing
- The faber-config skill resolves the complete inheritance chain
- Without resolution, inherited steps from parent workflows are lost
- This is the critical fix for issue #304
Parameters from Command:
target(string, optional): What to work on - artifact name, blog post, dataset, or natural languagework_id(string, optional): Work item ID for issue context and label detectionworkflow_override(string, optional): Explicit workflow selectionautonomy_override(string, optional): Explicit autonomy levelphases(string, optional): Comma-separated phases to execute (no spaces)step_id(string, optional): Specific step to execute (format:phase:step-name)prompt(string, optional): Additional custom instructionsworking_directory(string): Project root for config loadingresume(string, optional): Run ID to resume from (format:org/project/uuid)rerun(string, optional): Run ID to rerun with optional parameter changes
Validation Constraints:
- Either
targetORwork_idmust be provided (or both) - unlessresumeorrerunis specified phasesandstep_idare mutually exclusivephasesmust be comma-separated with no spacesstep_idmust match formatphase:step-nameresumeandrerunare mutually exclusiveresumeandrerunare mutually exclusive withtarget
Example Invocations
Artifact-first (primary use case):
target: "customer-analytics-v2"
work_id: "158"
→ Execute full workflow for artifact, linked to issue #158
Work-ID only (target inferred):
target: null
work_id: "158"
→ Fetch issue #158, infer target from title, execute full workflow
Phase selection:
target: "dashboard"
work_id: "200"
phases: "frame,architect"
→ Execute only frame and architect phases
Single step:
target: "api-refactor"
work_id: "300"
step_id: "build:implement"
→ Execute only the implement step in build phase
With custom instructions:
target: "feature-x"
work_id: "400"
prompt: "Focus on performance. Use caching."
→ Pass additional instructions to all phases
Natural language:
target: "implement the auth feature from issue 158"
work_id: null
→ Parse: target="auth feature", work_id="158", intent="build"
YOUR FINAL OUTPUT MUST BE:
🎯 FABER Workflow Complete
Target: {target}
Work ID: #{work_id}
Workflow: {workflow_id}
[faber-manager execution results here]
Phases Completed: frame, architect, build, evaluate, release
If your output is a JSON object with "status", "workflow", "phases" - YOU HAVE A BUG. That's intermediate data from faber-config (Step 0b), not the final result.
WORKFLOW STEPS (execute all in order)
Step 0: Initialize Execution Tracker (MANDATORY FIRST ACTION)
THIS STEP IS MANDATORY. DO NOT SKIP. DO NOT PROCEED TO STEP 0a UNTIL THIS IS DONE.
Use the TodoWrite tool NOW with this EXACT todo list:
[
{"content": "Step 0: Initialize execution tracker", "status": "in_progress", "activeForm": "Initializing execution tracker"},
{"content": "Step 0a: Load project configuration", "status": "pending", "activeForm": "Loading project configuration"},
{"content": "Step 0b: Resolve workflow inheritance via faber-config", "status": "pending", "activeForm": "Resolving workflow inheritance"},
{"content": "Step 0.5: Handle resume/rerun (if applicable)", "status": "pending", "activeForm": "Handling resume/rerun"},
{"content": "Step 1: Fetch issue data (if work_id provided)", "status": "pending", "activeForm": "Fetching issue data"},
{"content": "Step 2: Detect configuration from labels", "status": "pending", "activeForm": "Detecting label configuration"},
{"content": "Step 3: Apply configuration priority", "status": "pending", "activeForm": "Applying configuration priority"},
{"content": "Step 4: Resolve target", "status": "pending", "activeForm": "Resolving target"},
{"content": "Step 5: Validate phases/steps", "status": "pending", "activeForm": "Validating phases/steps"},
{"content": "Step 6: Check for prompt sources", "status": "pending", "activeForm": "Checking prompt sources"},

{"content": "Step 8: Route to faber-manager execution", "status": "pending", "activeForm": "Routing to faber-manager"},
{"content": "Step 9: Aggregate and return results", "status": "pending", "activeForm": "Aggregating results"}
]
AFTER TodoWrite confirms todos are created:
- Mark "Step 0: Initialize execution tracker" as "completed"
- Mark "Step 0a: Load project configuration" as "in_progress"
- Proceed to Step 0a below
This tracker enforces execution completion. You MUST NOT return until Step 9 is marked completed.
Step 0a: Load Project Configuration
CRITICAL: Load configuration and resolve workflow FIRST before any other processing.
Config Location: .fractary/plugins/faber/config.json (in project working directory)
TodoWrite: Mark "Step 0a: Load project configuration" as "in_progress"
1. Check if `.fractary/plugins/faber/config.json` exists
2. If not found → use default configuration:
- Default workflow: "fractary-faber:default"
- Default autonomy: "guarded"
3. If found → parse JSON and extract:
- Default workflow from config.default_workflow (or "fractary-faber:default")
- Default autonomy level
- Integration settings
Step 0a Transition:
- Store config values
- Use TodoWrite to mark "Step 0a: Load project configuration" as "completed"
- Use TodoWrite to mark "Step 0b: Resolve workflow inheritance via faber-config" as "in_progress"
- IMMEDIATELY proceed to Step 0b below - DO NOT RETURN HERE
Step 0b: Resolve workflow with inheritance (MANDATORY - FIX FOR #304)
CRITICAL EXECUTION REQUIREMENT: This step MUST actually invoke the faber-config skill.
Step 0b1: Determine workflow to resolve
Determine which workflow to resolve:
1. If workflow_override provided (from labels or CLI) → use that
2. Else if config.default_workflow exists → use that
3. Else → use "fractary-faber:default"
Store this as selected_workflow_id for next step
Step 0b2: Invoke faber-config skill to resolve workflow (MANDATORY)
IMMEDIATELY INVOKE: faber-config skill
Invoke Skill: faber-config
Operation: resolve-workflow
Parameters:
workflow_id: {selected_workflow_id}
(working_directory can be passed to specify project path)
WAIT FOR RESULT before proceeding to Step 0b3
Expected Result Structure:
{
"status": "success",
"workflow": {
"id": "default",
"inheritance_chain": ["fractary-faber:default", "fractary-faber:core"],
"phases": {
"frame": {
"enabled": true,
"steps": [
{"id": "core-fetch-or-create-issue", "source": "fractary-faber:core", "position": "pre_step"},
{"id": "core-switch-or-create-branch", "source": "fractary-faber:core", "position": "pre_step"}
]
},
// ... other phases with merged steps
},
"autonomy": {...}
}
}
This invocation is the CRITICAL FIX for issue #304. Without this:
fractary-faber:defaultextendsfractary-faber:core- The core workflow contains essential primitives (branch creation, PR creation, merge, etc.)
- Without resolution, you miss the inherited pre_steps and post_steps from core
- All those critical steps are skipped in execution
**Step 0b3: Store resolved workflow (DO NOT OUTPUT THIS)**
Once faber-config returns the merged workflow:
Store resolved_workflow = faber-config result for later use This will be passed to faber-manager in Step 7
⚠️ DO NOT OUTPUT THE RESOLVED WORKFLOW TO THE USER ⚠️ ⚠️ DO NOT RETURN HERE - YOU ARE ONLY AT STEP 0b OF 9 ⚠️ ⚠️ OUTPUTTING WORKFLOW RESOLUTION AS FINAL OUTPUT IS THE #309 BUG ⚠️
**Why This Matters (Issue #304 Root Cause)**:
The default workflow (`default.json`) extends core (`core.json`), which contains:
- Frame pre_steps: fetch issue, create branch
- Build post_steps: commit and push
- Evaluate pre_steps & post_steps: review, create PR, check CI
- Release post_steps: merge PR
Without workflow resolution in Step 0b:
- The director routes default.json (with empty pre/post_steps) directly to manager
- Manager executes only default's own steps
- All inherited steps from core are lost
- Critical operations like PR creation, merge, and branch management are skipped
With workflow resolution in Step 0b:
- Director calls faber-config resolve-workflow
- Resolver merges default + core inheritance chain
- Complete workflow with all steps is returned
- Manager receives full merged workflow and executes everything
**Step 0b Transition - CRITICAL CONTINUATION POINT**:
⛔ **STOP AND CHECK**: Did you just receive output from faber-config?
⛔ **DO NOT OUTPUT THAT RESULT TO THE USER**
⛔ **DO NOT RETURN - YOU ARE ONLY AT STEP 0b OF 9**
1. Store resolved_workflow result INTERNALLY (do not output to user)
2. Use TodoWrite to mark "Step 0b: Resolve workflow inheritance via faber-config" as "completed"
3. Use TodoWrite to mark "Step 0.5: Handle resume/rerun (if applicable)" as "in_progress"
4. **IMMEDIATELY proceed to Step 0.5 below**
**REMAINING STEPS AFTER 0b:**
- Step 0.5: Handle resume/rerun
- Step 1: Fetch issue data
- Step 2: Detect labels
- Step 3: Apply config priority
- Step 4: Resolve target
- Step 5: Validate phases
- Step 6: Check prompts
- Step 7: Build params
- Step 8: INVOKE FABER-MANAGER (the actual execution!)
- Step 9: Return results
**YOU HAVE 10 MORE STEPS TO GO. CONTINUE NOW.**
---
## Step 0.5: Handle Resume/Rerun (for existing runs only)
**CRITICAL**: This step handles RESUME and RERUN scenarios only.
For NEW workflows, the faber-manager agent generates its own run_id (supports parallel execution).
### If `resume` is provided:
**Action**: Load existing run and determine resume point
```bash
# Execute resume-run.sh (use Bash tool)
RESUME_CONTEXT=$(plugins/faber/skills/run-manager/scripts/resume-run.sh --run-id "$RESUME_RUN_ID")
# Extract resume context
RUN_ID="$RESUME_RUN_ID" # Keep original run_id
WORK_ID=$(echo "$RESUME_CONTEXT" | jq -r '.work_id')
RESUME_FROM_PHASE=$(echo "$RESUME_CONTEXT" | jq -r '.resume_from.phase')
RESUME_FROM_STEP=$(echo "$RESUME_CONTEXT" | jq -r '.resume_from.step')
COMPLETED_PHASES=$(echo "$RESUME_CONTEXT" | jq -r '.completed_phases')
Then: Pass run_id and resume_context to faber-manager in Step 8.
If rerun is provided:
Action: Load original run parameters (new run_id generated by manager)
# Execute rerun-run.sh to get original parameters (use Bash tool)
RERUN_CONTEXT=$(plugins/faber/skills/run-manager/scripts/rerun-run.sh --run-id "$RERUN_RUN_ID")
# Extract original parameters
ORIGINAL_PARAMS=$(echo "$RERUN_CONTEXT" | jq -r '.original_params')
WORK_ID=$(echo "$ORIGINAL_PARAMS" | jq -r '.work_id')
Then: Pass rerun_of context to faber-manager (manager generates new run_id).
If neither resume nor rerun (NEW workflow):
NO ACTION HERE - The faber-manager agent generates its own run_id as its first action. This design supports parallel execution where the director spawns multiple managers, each needing their own unique run_id.
Simply proceed to Step 1 (Fetch Issue Data).
Step 0.5 Transition:
- Store any resume/rerun context (or note "N/A - new workflow")
- Use TodoWrite to mark "Step 0.5: Handle resume/rerun (if applicable)" as "completed"
- Use TodoWrite to mark "Step 1: Fetch issue data (if work_id provided)" as "in_progress"
- IMMEDIATELY proceed to Step 1 below - DO NOT RETURN HERE
TodoWrite and Resume Behavior Clarification
Q: How does TodoWrite interact with resume/rerun scenarios?
A: TodoWrite is ALWAYS initialized fresh at the start of faber-director execution, regardless of resume/rerun.
The TodoWrite tracker is for faber-director's own execution flow, not for workflow state persistence:
| Scenario | TodoWrite Behavior | Workflow State |
|---|---|---|
| New workflow | Fresh 12-step tracker | New run_id generated by manager |
| Resume | Fresh 12-step tracker | Resume context loaded from file |
| Rerun | Fresh 12-step tracker | Original params loaded, new run_id |
Key distinction:
- TodoWrite tracks faber-director's 12 steps within THIS invocation
- Workflow state (resume/rerun) is loaded from persistent storage in Step 0.5
- These are independent concerns - TodoWrite ensures director completes, workflow state ensures manager resumes correctly
Example - Resume scenario:
- User runs
/fractary-faber:run --resume fractary/project/abc123 - faber-director initializes fresh TodoWrite (12 pending steps)
- Step 0.5 loads resume context from
abc123run file - Steps 1-7 execute (some may short-circuit based on resume context)
- Step 8 passes
is_resume: trueandresume_contextto faber-manager - faber-manager resumes from the saved checkpoint
- All 12 TodoWrite steps still complete (director's flow is complete)
Step 1: Fetch Issue Data (if work_id provided)
Condition: Only if work_id is provided
Action:
1. Use /fractary-work:issue-fetch {work_id} via SlashCommand tool
2. Extract from response:
- title: Issue title
- description: Issue body
- labels: Array of labels
- state: open/closed
- url: Issue URL
3. Store issue data for later use
If issue not found:
Error: Issue #{work_id} not found
Please verify the issue ID exists
Then ABORT with error (see TERMINATION_RULES for error handling).
Step 1 Transition:
- Store issue data (or note "N/A - no work_id provided")
- Use TodoWrite to mark "Step 1: Fetch issue data (if work_id provided)" as "completed"
- Use TodoWrite to mark "Step 2: Detect configuration from labels" as "in_progress"
- IMMEDIATELY proceed to Step 2 below - DO NOT RETURN HERE
Step 2: Detect Configuration from Labels
Note: Step 1.5 (Initialize Run Directory) was removed. The faber-manager agent now generates run_id and initializes the run directory as its first action (Step 0). This supports parallel execution where each manager has its own run_id.
Condition: Only if issue data was fetched
Label Pattern: faber:<argument>=<value>
Supported Labels:
| Label Pattern | Extracts |
|---|---|
faber:workflow=<id> |
workflow |
faber:autonomy=<level> |
autonomy |
faber:phase=<phases> |
phases (comma-separated) |
faber:step=<step-id> |
step_id |
faber:target=<name> |
target |
faber:skip-phase=<phase> |
phase to exclude |
Legacy Labels (backwards compatibility):
workflow:<id>→ workflowautonomy:<level>→ autonomy
Extraction Logic:
For each label in issue.labels:
If label matches "faber:(\w+)=(.+)":
argument = match[1]
value = match[2]
Store label_config[argument] = value
Else if label matches "workflow:(.+)":
Store label_config["workflow"] = match[1]
Else if label matches "autonomy:(.+)":
Store label_config["autonomy"] = match[1]
Step 2 Transition:
- Store label_config values (or empty object if no labels/issue)
- Use TodoWrite to mark "Step 2: Detect configuration from labels" as "completed"
- Use TodoWrite to mark "Step 3: Apply configuration priority" as "in_progress"
- IMMEDIATELY proceed to Step 3 below - DO NOT RETURN HERE
Step 3: Apply Configuration Priority
Priority Order (highest to lowest):
- CLI arguments (from command)
- Issue labels (
faber:*prefixed) - Legacy labels (
workflow:*,autonomy:*) - Config file defaults
- Hardcoded fallbacks
Merge Logic:
final_config = {
"workflow": cli.workflow_override or labels.workflow or config.default_workflow or "default",
"autonomy": cli.autonomy_override or labels.autonomy or config.default_autonomy or "guarded",
"phases": cli.phases or labels.phases or "all",
"step_id": cli.step_id or labels.step_id or null,
"target": cli.target or labels.target or issue.title or null,
}
Step 3 Transition:
- Store final_config
- Use TodoWrite to mark "Step 3: Apply configuration priority" as "completed"
- Use TodoWrite to mark "Step 4: Resolve target" as "in_progress"
- IMMEDIATELY proceed to Step 4 below - DO NOT RETURN HERE
Step 4: Resolve Target
Cases:
- Explicit target provided: Use as-is
- Natural language target: Parse for artifact and intent
- No target but work_id: Infer from issue title
- Neither: Error
Natural Language Parsing:
When target contains natural language, extract:
- Artifact name: What to create/modify
- Work item references: Issue numbers mentioned
- Phase intent: Keywords like "design", "build", "test"
| Input | Extracted |
|---|---|
"implement auth from issue 158" |
target="auth", work_id="158", intent=build |
"just design the data pipeline" |
target="data pipeline", phases=frame,architect |
"test the changes for issue 200" |
work_id="200", phases=evaluate |
Target Inference from Issue:
If no target but work_id provided:
target = slugify(issue.title)
Example: "Add CSV export feature" → "csv-export-feature"
Step 4 Transition:
- Store resolved target
- Use TodoWrite to mark "Step 4: Resolve target" as "completed"
- Use TodoWrite to mark "Step 5: Validate phases/steps" as "in_progress"
- IMMEDIATELY proceed to Step 5 below - DO NOT RETURN HERE
Step 5: Validate Phases/Steps
If phases specified:
Validation:
- Split by comma (no spaces allowed)
- Each phase must be one of: frame, architect, build, evaluate, release
- Phases must be in valid order (no release before build, etc.)
- All phases must be enabled in workflow config
Phase Dependencies:
architectassumesframecomplete (unless included)buildassumesarchitectcomplete (unless included)evaluateassumesbuildcomplete (unless included)releaseassumesevaluatecomplete (unless included)
Check State:
If phases doesn't include prerequisite:
Check state file for prerequisite completion
If not complete: Warn user but allow (they may know what they're doing)
If step_id specified:
Validation:
- Must match pattern
phase:step-name - Phase must be valid (frame, architect, build, evaluate, release)
- Step must exist in workflow config for that phase
Extract:
step_id = "build:implement"
step_phase = "build"
step_name = "implement"
Validate step_name exists in config.phases.build.steps[*].name
Step 5 Transition:
- Store validated phases/step_id
- Use TodoWrite to mark "Step 5: Validate phases/steps" as "completed"
- Use TodoWrite to mark "Step 6: Check for prompt sources" as "in_progress"
- IMMEDIATELY proceed to Step 6 below - DO NOT RETURN HERE
Step 6: Check for Prompt Sources
CLI Prompt:
If prompt parameter provided, use it as additional_instructions.
Issue Body Prompt:
If no CLI prompt, check issue body for faber-prompt code block:
```faber-prompt
Focus on performance.
Use caching where appropriate.
**Extract:**
If issue.description contains "```faber-prompt" block: additional_instructions = content of that block
**Priority:**
1. CLI `--prompt` argument (highest)
2. `faber-prompt` block in issue body
3. No additional instructions
**Step 6 Transition**:
1. Store additional_instructions (or null)
2. Use TodoWrite to mark "Step 6: Check for prompt sources" as "completed"
3. Use TodoWrite to mark "Step 7: Build manager parameters" as "in_progress"
4. **IMMEDIATELY proceed to Step 7 below - DO NOT RETURN HERE**
---
## Step 7: Build Manager Parameters
**Construct parameters for faber-manager agent:**
### For NEW workflows (no resume/rerun):
```json
{
"target": "resolved-target-name",
"work_id": "158",
"source_type": "github",
"source_id": "158",
"workflow_id": "fractary-faber:default",
"resolved_workflow": {
"id": "default",
"inheritance_chain": ["fractary-faber:default", "fractary-faber:core"],
"phases": {
"frame": { "enabled": true, "pre_steps": [...], "steps": [...], "post_steps": [...] },
"architect": { "enabled": true, "pre_steps": [...], "steps": [...], "post_steps": [...] },
"build": { "enabled": true, "pre_steps": [...], "steps": [...], "post_steps": [...] },
"evaluate": { "enabled": true, "max_retries": 3, "pre_steps": [...], "steps": [...], "post_steps": [...] },
"release": { "enabled": true, "require_approval": true, "pre_steps": [...], "steps": [...], "post_steps": [...] }
},
"autonomy": { "level": "guarded", "require_approval_for": ["release"] }
},
"autonomy": "guarded",
"phases": null,
"step_id": null,
"additional_instructions": "Focus on performance...",
"worktree": true,
"is_resume": false,
"resume_context": null,
"issue_data": {
"title": "Issue title",
"description": "Issue body",
"labels": ["type: feature", "faber:workflow=default"],
"url": "https://github.com/..."
},
"working_directory": "/path/to/project"
}
Note: run_id is NOT passed for new workflows. The faber-manager agent generates its own
run_id as its first action. This supports parallel execution where each manager needs a unique run_id.
Key Mappings:
resolved_workflow: FULLY RESOLVED workflow with inheritance merged (from faber-config resolve-workflow) - CRITICALphases: Array from comma-separated string, or null for all phasesstep_id: String in formatphase:step-name, or nulladditional_instructions: Merged prompt from CLI and/or issueworktree: Always true (isolation is mandatory)is_resume: False for new workflowsworking_directory: Project root path for the manager to operate in
For RESUME scenarios:
{
"run_id": "fractary/project/original-uuid",
"is_resume": true,
"resume_context": {
"resume_from": {"phase": "build", "step": "implement"},
"completed_phases": ["frame", "architect"],
"completed_steps": {"build": ["setup"]}
},
"target": "...",
"work_id": "...",
...
}
For resume, the run_id IS passed because we're continuing an existing run.
Step 7 Transition:
- Store manager_params object
- Use TodoWrite to mark "Step 7: Build manager parameters" as "completed"
- Use TodoWrite to mark "Step 8: Route to faber-manager execution" as "in_progress"
- IMMEDIATELY proceed to Step 8 below - DO NOT RETURN HERE
Step 8: Route to Execution (THE MAIN EVENT)
🚨 THIS IS THE MOST IMPORTANT STEP - ACTUALLY INVOKE FABER-MANAGER 🚨
⚠️ CRITICAL RULES FOR STEP 8:
- You MUST actually invoke the Task tool with the faber-manager agent
- You MUST NOT just describe what should happen - ACTUALLY DO IT
- You MUST wait for the faber-manager result before proceeding
- Returning intermediate outputs (like workflow resolution) is NOT completion
- If you haven't called Task(subagent_type="fractary-faber:faber-manager"...), you haven't done Step 8
CHECK YOURSELF:
- Did you just invoke faber-config? That was Step 0b. You're not done.
- Did you just fetch the issue? That was Step 1. You're not done.
- Did you just build manager params? That was Step 7. You're not done.
- Only invoking faber-manager completes Step 8.
Single Work Item
Invoke faber-manager agent using Task tool:
Task(
subagent_type="fractary-faber:faber-manager",
description="Execute FABER workflow for {target}",
prompt='{
"run_id": "fractary/claude-plugins/a1b2c3d4-...",
"target": "customer-analytics",
"work_id": "158",
"source_type": "github",
"source_id": "158",
"workflow_id": "default",
"autonomy": "guarded",
"phases": ["frame", "architect", "build"],
"step_id": null,
"additional_instructions": "Focus on performance",
"worktree": true,
"is_resume": false,
"issue_data": {...},
"resolved_workflow": {...} # IMPORTANT: Include the resolved workflow from Step 0b2
}'
)
AFTER invocation:
- Wait for faber-manager result
- Include the result in your response
- Only then return control to user
- Do NOT return intermediate skill outputs as final results
Step 8 Error Handling
If faber-manager invocation fails:
The Task tool may fail for various reasons. Handle each case explicitly:
| Error Type | Handling | TodoWrite Status |
|---|---|---|
| Task tool error | Report error, abort | Step 8 stays "in_progress" |
| Manager returns error | Report error details, abort | Step 8 stays "in_progress" |
| Manager timeout | Report timeout, suggest retry | Step 8 stays "in_progress" |
| Network failure | Report failure, suggest retry | Step 8 stays "in_progress" |
Error response format:
❌ FABER Director: Step 8 Failed
Error: faber-manager invocation failed
Type: [Task tool error | Manager error | Timeout | Network]
Details: [error message from Task tool or manager]
Completed Steps: 0a, 0b, 0.5, 1, 2, 3, 4, 5, 6, 7
Failed Step: 8 (Route to faber-manager execution)
State preserved:
- resolved_workflow: ✓ Available
- issue_data: ✓ Available
- manager_params: ✓ Built
Suggested next steps:
1. Review error details above
2. Check faber-manager agent logs if available
3. Retry: /fractary-faber:run --work-id {work_id}
4. Or debug: Check plugins/faber/agents/faber-manager.md
CRITICAL: Do NOT mark Step 8 as "completed" if the manager invocation fails. Leave it as "in_progress" so the user knows where execution stopped.
Multiple Work Items (Parallel)
If natural language mentions multiple issues or comma-separated work_ids:
Invoke multiple faber-manager agents in ONE message:
// All Task calls in ONE message = parallel execution
Task(
subagent_type="fractary-faber:faber-manager",
description="Execute FABER workflow for issue #100",
prompt='{"target": "...", "work_id": "100", ...}'
)
Task(
subagent_type="fractary-faber:faber-manager",
description="Execute FABER workflow for issue #101",
prompt='{"target": "...", "work_id": "101", ...}'
)
Limits:
- Maximum 10 parallel workflows (safety)
- If more than 10: batch into groups
Step 8 Transition:
- Store manager invocation result(s)
- Use TodoWrite to mark "Step 8: Route to faber-manager execution" as "completed"
- Use TodoWrite to mark "Step 9: Aggregate and return results" as "in_progress"
- IMMEDIATELY proceed to Step 9 below - DO NOT RETURN HERE
Step 9: Aggregate Results
Single Work Item
Return faber-manager result directly.
Multiple Work Items
Aggregate results from all agents:
🎯 Batch Workflow Complete: 3 issues
✅ Issue #100: Complete (PR #110)
✅ Issue #101: Complete (PR #111)
❌ Issue #102: Failed at Evaluate phase
Summary: 2/3 successful
Step 9 Transition (FINAL):
- Format results for user display
- Use TodoWrite to mark "Step 9: Aggregate and return results" as "completed"
- Verify ALL 13 steps are marked "completed" in TodoWrite (Step 0 through 9)
- NOW you may return the final results to the user
⚠️ FINAL CHECKPOINT BEFORE RETURNING ⚠️
BEFORE YOU RETURN ANY RESPONSE, VERIFY:
TodoWrite Check:
[ ] Step 0: Initialize execution tracker - COMPLETED?
[ ] Step 0a: Load project configuration - COMPLETED?
[ ] Step 0b: Resolve workflow inheritance via faber-config - COMPLETED?
[ ] Step 0.5: Handle resume/rerun - COMPLETED?
[ ] Step 1: Fetch issue data - COMPLETED?
[ ] Step 2: Detect configuration from labels - COMPLETED?
[ ] Step 3: Apply configuration priority - COMPLETED?
[ ] Step 4: Resolve target - COMPLETED?
[ ] Step 5: Validate phases/steps - COMPLETED?
[ ] Step 6: Check for prompt sources - COMPLETED?
[ ] Step 7: Build manager parameters - COMPLETED?
[ ] Step 8: Route to faber-manager execution - COMPLETED? (Did you ACTUALLY invoke Task tool?)
[ ] Step 9: Aggregate and return results - COMPLETED?
Execution Check:
[ ] faber-config was ACTUALLY invoked (not just documented)?
[ ] faber-manager was ACTUALLY invoked via Task tool (not just planned)?
[ ] faber-manager result is present in your response?
IF ANY BOX IS UNCHECKED:
- STOP - DO NOT RETURN
- Find the first unchecked step
- Execute that step
- Continue until all boxes are checked
ONLY RETURN WHEN ALL BOXES ARE CHECKED.
- Step 9 "Aggregate and return results" is marked "completed" in TodoWrite
- The faber-manager Task tool invocation has returned a result
- The result has been formatted for user display
OR when an error occurs (see ERROR HANDLING below)
YOU ARE NOT ALLOWED TO RETURN WHEN:
- Any step from 0a through 8 is still "pending" or "in_progress" (unless error)
- faber-config has returned but faber-manager has not been invoked
- A sub-skill or sub-agent returns an intermediate result
IF YOU FIND YOURSELF ABOUT TO RETURN EARLY:
- STOP
- Check TodoWrite - which steps are incomplete?
- Resume from the first incomplete step
- Continue until Step 9 is complete
ERROR HANDLING:
When an error occurs at ANY step:
- IMMEDIATELY abort further execution
- Report the error with FULL context:
- Which step failed
- What the error was
- What state was achieved before failure
- Suggest specific next steps to resolve the error
- Mark the failed step as "in_progress" (not completed)
- Return to user with error report
Do NOT:
- Silently fail and return nothing
- Continue to next step after error
- Retry without user instruction
RETURNING WORKFLOW RESOLUTION AS FINAL OUTPUT IS A BUG. THE FIX FOR #304 REQUIRES FABER-MANAGER INVOCATION. THE FIX FOR #309 REQUIRES ALL 13 STEPS COMPLETING (Step 0 through Step 9).
TodoWrite Verification (FIX FOR #309): All 13 steps must be marked "completed" in your TodoWrite tracker:
- Step 0: Initialize execution tracker - completed
- Step 0a: Load project configuration - completed
- Step 0b: Resolve workflow inheritance via faber-config - completed
- Step 0.5: Handle resume/rerun (if applicable) - completed
- Step 1: Fetch issue data (if work_id provided) - completed
- Step 2: Detect configuration from labels - completed
- Step 3: Apply configuration priority - completed
- Step 4: Resolve target - completed
- Step 5: Validate phases/steps - completed
- Step 6: Check for prompt sources - completed
- Step 7: Build manager parameters - completed
- Step 8: Route to faber-manager execution - completed
- Step 9: Aggregate and return results - completed
Execution Verification (FIX FOR #304):
- faber-config skill was ACTUALLY invoked in Step 0b (not just documented)
- resolved_workflow is populated with merged inheritance chain
- faber-manager agent was ACTUALLY invoked via Task tool in Step 8 (not just planned)
- faber-manager result is present in this response
- If multiple work items, ALL manager results are present
IF ANY CHECKBOX IS UNCHECKED:
- You are NOT complete
- Find the first unchecked TodoWrite step
- Resume from that step
- Continue until Step 9 is marked completed
COMMON FAILURE MODES TO AVOID:
- Returning after faber-config without invoking faber-manager (THE #304 BUG)
- Returning workflow resolution JSON as final output (THE #309 BUG)
- Skipping TodoWrite initialization (Step 0)
- Not actually invoking Task tool in Step 8 (just describing it)
- Not marking todos as completed after each step

Issue #304 Fix Summary
Problem: FABER Director skips workflow inheritance resolution, causing all inherited steps from core.json to be lost when executing default.json.
Root Cause: Step 0b (Resolve workflow with inheritance) in faber-director SKILL.md only contained documentation but no actual execution instructions. The LLM never invoked faber-config resolve-workflow.
Solution: Added explicit Step 0b2 execution instructions to invoke faber-config skill and wait for resolved workflow before routing to manager.
Critical Change: faber-director now MUST invoke faber-config in Step 0b2 before proceeding. This ensures:
- All inherited steps from parent workflows are merged
- Complete workflow with all pre_steps, steps, and post_steps is resolved
- Resolved workflow is passed to faber-manager in Step 8
- Manager executes all steps including critical primitives from core
Files Changed:
plugins/faber/skills/faber-director/SKILL.md- Added Step 0b2 execution instructions
Verification: Ensure that workflow execution now includes all inherited steps like branch creation, PR creation, and PR merge.
Issue #309 Fix Summary (v2 - Aggressive Restructure)
Problem: FABER Director stops prematurely after sub-skill invocations (faber-config) instead of continuing through all workflow steps. The skill outputs workflow resolution JSON and terminates.
Root Cause (v1 fix failed): The original fix placed <MANDATORY_FIRST_ACTION> section BEFORE <WORKFLOW>. The LLM subagent jumps straight to <WORKFLOW> to start execution, completely skipping the TodoWrite initialization. Without the tracker, the LLM interprets faber-config's return as a natural stopping point.
Solution (v2): Move TodoWrite initialization INTO the <WORKFLOW> section:
- Added "Step 0: Initialize Execution Tracker" as FIRST step inside
<WORKFLOW>section - Added aggressive "DO NOT OUTPUT" warnings after Step 0b (faber-config returns)
- Added remaining steps countdown at critical transition points
- Added final checkpoint verification at end of
<WORKFLOW>section - Strengthened Step 8 to emphasize ACTUAL Task tool invocation
Critical Changes:
- Step 0 (new): Initialize TodoWrite tracker - INSIDE
<WORKFLOW>so it cannot be skipped - Step 0b transition: Explicit "DO NOT OUTPUT THIS RESULT" warnings
- Step 8: "THE MAIN EVENT" header with "CHECK YOURSELF" verification
- End of WORKFLOW: Full checkbox verification before returning
Files Changed:
plugins/faber/skills/faber-director/SKILL.md- Aggressive restructure of TodoWrite enforcement
Verification: Run /fractary-faber:run --work-id <id> and verify:
- All 13 TodoWrite steps progress from pending → in_progress → completed
- Step 0 initializes tracker FIRST
- faber-config is invoked (Step 0b) but result is NOT output to user
- Issue is fetched (Step 1)
- faber-manager is ACTUALLY invoked via Task tool (Step 8)
- Final result includes manager output (Step 9)
