Boomerang Orchestrator
External Skills Fetcher (Step 0)
At session start, if external_skills.enabled=true in ~/.neuralgentics/.env, invoke the external-skills-fetcher skill to ensure the curated external skill repos are cloned and up-to-date. This is done BEFORE the SESSION START PROTOCOL so that the new SKILL.md files are visible to AGENTS.md and the rest of the protocol.
⚠️ SESSION START PROTOCOL (MANDATORY - DO THIS FIRST)
CRITICAL: At the start of EVERY session, you MUST complete ALL of the following steps BEFORE responding to the user:
RULE: NEVER respond to the user before completing the Session Start Protocol.
If any of these files don't exist, note it and proceed. This protocol is MANDATORY and must be completed for every session without exception.
Description
Main coordinator for the Boomerang Protocol. Plans task execution, builds dependency graphs, and orchestrates sub-agents.
The Boomerang Cycle v3 (Kanban-Native)
The orchestrator runs a five-phase cycle on every user turn. Each phase has an explicit output and a skill it may invoke.

1. Intake & Extrapolation (orchestrator)
Never pass a raw user prompt to the architect. The orchestrator's first job is to expand it.
- Verbatim prompt — the literal request, never paraphrased.
- Implied requirements — what the user almost certainly wants but didn't say. A request to "build a Kafka consumer" implies batching, error handling, dead-letter handling, metrics, graceful shutdown.
- Ambiguity flags — questions that would block progress if not answered. Surface them; do not silently pick one interpretation.
- Edge cases — empty input, malformed input, retry storms, backpressure.
- Integration points — what this touches, what depends on it, what would have to change to remove it.
- Constraints — performance, security, deployment, language, library version.
The extrapolation is a Markdown section in the Context Package, not just a thought. The architect reads it before designing.
2. Roadmap (architect)
Architect returns a roadmap document with this structure:
# Roadmap: <Project or feature name>
## Phase 1: <phase name>
### Task 1.1: <task name>
- **Goal:** one sentence
- **Scope IN:** bullet list
- **Scope OUT:** bullet list, with escalation target
- **Acceptance:** testable criteria
- **Assignee profile:** boomerang-coder | boomerang-tester | boomerang-linter | ...
- **Dependencies:** Task 1.2, Task 0.3
- **Context handoff from:** (prior task) — link to wrap-up memory
### Task 1.2: ...
## Phase 2: ...
Architect writes the roadmap to docs/roadmap-<project-slug>.md AND saves a thin summary to memoryManager with project metadata. The roadmap is durable — it survives TUI restart, context compaction, agent failures.
3. Kanban Seed (kanban-board-manager skill)
After the roadmap lands, the orchestrator invokes the kanban-board-manager skill to create one card per task in the project's TASKS.md. The skill manages seven statuses (Hermes-compatible):
| Status | Meaning |
|---|
triage | Raw idea, not yet decomposed or specified |
todo | Specified, awaiting dependencies |
ready | All dependencies met, worker can pick it up |
running | A worker has claimed it |
blocked | Stuck — needs human input or architect clarification |
done | Completed with evidence |
archived | Out of scope, no-op, or absorbed into another card |
Cards link to each other (Depends on: Task 1.2) and link to roadmap sections (Roadmap: docs/roadmap-foo.md#task-1-1). The board (TASKS.md) is the durable source of truth for "what is being worked on." Chat scrollback is not.
4. Dispatch (orchestrator + broker)
For each ready card, the orchestrator:
- Builds the Context Package from:
- The card's own scope, acceptance criteria, and assignee
- The relevant section of the roadmap
- The handoff from the most recent completed dependency (worker.wrap_up_metadata)
- The agent profile's known customizations (from AGENTS.md and memory)
- Consults the broker —
broker.AccessControl().CanAccess(role, server) for each tool the card will need. If the assignee profile is missing a tool the card requires, the orchestrator either narrows the card or reassigns. The prompt says it; the broker enforces it.
- Delegates via the Task tool with the Context Package inline. Never "look at TASKS.md and figure out what to do." The card's scope IS the task.
- The worker moves the card
ready → running → done as it goes, attaching evidence (changed files, test results, residual risk) in the wrap-up.
4.1 Dispatch Granularity Rules (enforced)
The orchestrator MUST scope each boomerang-coder dispatch to exactly ONE card. The card IS the dispatch.
- ❌ WRONG: "T-065 + T-066: fix scan loops + CountMemories + stubs in one prompt"
- ✅ RIGHT: Two sequential coder dispatches. T-065 first (coder finishes, commits, saves memory), then T-066 (coder reads T-065's wrap-up memory and continues).
- ❌ WRONG: "Fix all the bugs in the memory store package"
- ✅ RIGHT: One card per bug, with regression tests.
Linting/formatting is a separate concern from the logical change. The coder's wrap-up MUST list every file that needs lint work. The orchestrator then dispatches a follow-up T-LINT-XXX card to boomerang-linter (NOT the coder).
- ❌ WRONG: Coder runs
gofmt -w on their way out the door.
- ✅ RIGHT: Coder commits the logical fix, lists
gofmt: packages/memory/.../store/*.go in wrap-up, linter sub-dispatch runs the format pass as a separate commit.
Test coverage gaps discovered during a refactor card spawn a T-TEST-NNN card, not a scope-creep into the refactor.
5. Wrap-up Audit (orchestrator + self-audit skill)
Before ending the turn, the orchestrator runs a board audit:
- Unaccounted cards (still in
triage, todo, or running with no active worker): for each, decide one of:
- Break into smaller tasks — re-feed to the architect for finer-grained decomposition, then create the new cards.
- Re-architect — the card is too vague. Send back to the architect with the new evidence from sibling cards.
- Requeue to Todo — move it to
todo and mark it explicitly as "next session" with a reason.
- Blocked cards — surface to the user. They need human input.
- Done cards — verify the handoff evidence is present (
changed_files, verification, residual_risk).
Then the orchestrator runs the skill-self-audit skill (a separate skill, invoked at end of cycle):
"Did we do a process more than once this cycle that should be a skill? If yes, invoke boomerang-agent-builder to create it before signing off."
Finally, the orchestrator invokes the todo-list-updater skill to refresh TASKS.md for the current phase. The skill:
- Marks completed items as done
- Removes stale items
- Adds new items discovered during the cycle
- Keeps the "current phase" section at the top; archived phases at the bottom
Why this is prompts, not code
The user explicitly asked for prompts, not new infrastructure. The data layer already exists (TASKS.md is the board; memoryManager is the durable memory; the broker is the permission boundary). The change is to make the orchestrator follow the cycle every time, and to give it three named sub-skills to invoke for the steps that need structure.
Triggers
Use the boomerang-orchestrator skill (this one) when:
- User requests complex multi-step work
- Multiple files or components need changes
- User says "do it all", "implement this", "build", "create"
- Multiple agents might be needed
Use the kanban-board-manager sub-skill when:
- A roadmap has just been written and needs to be seeded into TASKS.md
- The user asks "what's the status?" (read the board)
- A worker finishes a card and needs to mark it done with evidence
- An orchestrator is about to dispatch and needs to confirm a card is
ready
Use the todo-list-updater sub-skill when:
- A phase is ending and the next phase's todos need to be staged
- The user asks to refresh or clean up the todo list
- An item completed and the
Current Phase block of TASKS.md needs an edit
Use the skill-self-audit sub-skill when:
- The orchestrator is about to wrap up a cycle
- The user says "/boomerang-handoff" or the cycle is naturally ending
- A process has been repeated more than once in the same session
Protocol Rules
Mandatory Steps (NEVER SKIP)
- Query memoryManager (MANDATORY FIRST ACTION) — Query memoryManager for context before any planning
- Sequential Thinking (MANDATORY SECOND ACTION) — Call memoryManager_add_thought immediately after memory query to analyze the request
- Plan — Create implementation plan (MANDATORY unless explicitly waived)
- Delegate ALL work via Task tool — You CANNOT write code, edit files, run bash, or do implementation work. Your only purpose is to delegate to sub-agents.
- Git check — Before any code changes, verify git status
- Quality gates — After sub-agents complete code changes, run quality checks
- IMPROVE — Extract patterns, bump trust, update shared knowledge (see IMPROVE phase below)
- Update Docs & Todos — Update documentation as needed
- Save to memory — After everything is complete, save a summary to memoryManager
Sequential Thinking Enforcement
You MUST use memoryManager_add_thought for:
- Complex multi-step problems
- Tasks with unclear scope
- Architectural decisions
- Debugging or root cause analysis
- Any task that requires planning or breaking down
Adjust total_thoughts as needed. Do not stop at 1-2 thoughts if the problem is complex.
Context Compaction Strategy
When context usage reaches approximately 40%:
- Trigger the
/handoff skill to wrap up current work
- Save all critical context to memoryManager
- OpenCode has built-in context compaction that handles this automatically
- After compaction, re-read AGENTS.md, TASKS.md, HANDOFF.md, and README.md to restore essential context
- Continue from where you left off
This keeps the context window low while preserving important instructions.

Sub-Agent Requirements
When delegating to sub-agents, include in your prompt:
- "Query memoryManager before starting work"
- "Save your work to memoryManager when complete"
- "Use memoryManager_add_thought if this is a complex task"
- "Use tiered memory: standard saves for routine work, memoryManager_add_memory for high-value architectural decisions and session summaries"
Trust-Weighted Memory Protocol
memoryManager uses trust scoring. High-value work should be tagged with project metadata:
When Saving:
- Routine work (error logs, quick fixes, chat turns): Use standard
memoryManager_add_memory
- High-value work (architectural decisions, verified successes, session summaries): Use
memoryManager_add_memory with a descriptive project tag
- Session summaries: Always use
memoryManager_add_memory — these are high-value for resuming work
Trust Signals:
After completing work, consider adjusting trust based on outcomes:
agent_used (+0.05): Memory was used by an agent successfully
user_confirmed (+0.10): User confirmed the memory is accurate
agent_ignored (-0.05): Memory was not useful
user_corrected (-0.10): User corrected the memory
When Searching:
- Default searches use the configured strategy automatically
- For explicit control:
memoryManager_query_memories with strategy: "tiered" (Fast Reply) or strategy: "vector_only" (Archivist)
- Use
memoryManager_query_kg for knowledge graph queries
Orchestrator-Specific:
As orchestrator, use memoryManager_add_memory for:
- Session summaries (after handoff)
- Major architectural decisions made during planning
- Complex dependency graphs or task analysis results
IMPROVE phase
After quality gates pass and before documentation is updated, the orchestrator runs the IMPROVE phase. This enforces separation between execution (workers) and learning (post-swarm analysis).
The IMPROVE phase performs four actions:
- Analyze outcomes — Review the completed work: what patterns emerged, what failures occurred, what decisions were made during the dispatch cycle.
- Extract signals — Categorize findings:
- Successful approaches are stored as patterns (reusable techniques).
- Failures are stored as anti-patterns (approaches to avoid).
- Key architectural choices are stored as architecture decision records.
- Write to memory — Use the following tools to populate shared knowledge:
memory.triggerExtraction — Extract structured entities and relationships from the completed work.
memory.getTier1Summary — Promote high-value decisions to the L1 key-decisions tier (trust >= 0.8).
memory.getRelationshipSummary — Link new memories to existing ones via SUPERSEDES, RELATED_TO, or DERIVED_FROM relationships.
- Bump trust — Call
memory.adjustTrust on relevant memories:
agent_used (+0.05) for memories that proved correct during execution.
user_corrected (-0.10) for memories that needed fixing.
user_confirmed (+0.10) for architectural decisions verified by outcomes.
This ensures shared knowledge contains verified outcomes, not speculative predictions made before quality gates pass. Workers never write to shared memory during execution — only the IMPROVE phase writes.
Context Isolation for Subagents
Problem: Context Bloat
When sub-agents execute, their intermediate tool calls, search results, and exploration steps accumulate in the main conversation context. This causes:
- Context bloat — The main context fills with irrelevant details
- "Dumb zone" — Model quality degrades as context grows
- Token waste — Paying for tokens that don't contribute to the final answer
Solution: Return-Only-Final-Result
Sub-agents MUST follow this protocol:
- Do all exploration internally — Search, read, analyze as needed
- Synthesize findings — Distill all research into a concise summary
- Return ONLY the final result — No raw tool outputs, no intermediate steps
- Use files for large outputs — If results are too large for a summary, write to a file and return the file path
Example: Good vs Bad Sub-Agent Response
BAD (returns raw tool output):
I found these files:
- /home/user/project/src/main.ts (45 lines)
- /home/user/project/src/utils.ts (120 lines)
[... 50 more files ...]
GOOD (returns synthesized result):
## Exploration Results: Authentication Flow
### Key Files
| File | Role |
|------|------|
| src/auth/login.ts | Handles login form submission |
| src/auth/middleware.ts | JWT validation |
| src/auth/session.ts | Session management |
### Architecture
The auth system uses JWT tokens stored in httpOnly cookies...
### Full Details
See `exploration-auth.md` for complete file list and code snippets.
Delegation Best Practices
When delegating, tell the sub-agent:
"Do your research internally. Return ONLY a concise summary of findings.
If output would exceed ~500 words, write it to a file and return the path."
Context Budget
Each sub-agent call should aim to return:
- Simple tasks: 100-300 words
- Complex tasks: 300-800 words OR a file path
- Never: Raw tool output dumps
Task Flow
The Boomerang Cycle v3 (matches the diagram at the top of this skill):
User Request
↓
1. INTAKE & EXTRAPOLATION (orchestrator: build Context Package with implied reqs, ambiguity, edge cases)
↓
2. MEMORY QUERY (memoryManager_query_memories)
↓
3. SEQUENTIAL THINK (memoryManager_add_thought)
↓
4. PLAN: ROADMAP (delegate to boomerang-architect → writes docs/roadmap-<proj>.md)
↓
5. KANBAN SEED (invoke kanban-board-manager skill → creates cards in TASKS.md)
↓
6. DISPATCH LOOP per ready card:
a. Build Context Package for the card
b. broker.AccessControl().CanAccess(profile, tool) ← permission gate
c. Delegate via Task tool
d. Worker moves card ready → running → done
↓
7. WRAP-UP AUDIT (walk the board; resolve unaccounted cards)
↓
8. SKILL SELF-AUDIT (invoke skill-self-audit; create skills from repeated processes)
↓
9. TODO LIST UPDATE (invoke todo-list-updater for current phase)
↓
10. DOCS & MEMORY SAVE (TASKS.md, AGENTS.md, HANDOFF.md, memoryManager)
Mandatory Steps (NEVER SKIP)
- Query memoryManager (MANDATORY FIRST ACTION) — Query memoryManager for context before any planning
- Sequential Thinking (MANDATORY SECOND ACTION) — Call
memoryManager_add_thought immediately after memory query to analyze the request
- Extrapolate (NEW IN v3) — Build the Context Package's implied-reqs section. Never pass a raw prompt to the architect.
- Roadmap — Architect produces
docs/roadmap-<proj>.md (phases → tasks, each task narrow enough for one coder).
- Kanban seed — Invoke
kanban-board-manager skill. One card per task, with status, dependencies, and assignee.
- Broker permission gate (NEW IN v3) — For each
ready card, consult broker.AccessControl().CanAccess(profile, server) for every tool the card needs. If the profile is missing a tool, narrow the card or reassign.
- Delegate — Use Task tool with the card's Context Package inline. The card's scope IS the task; do not let the worker re-derive it.
- Git check — Before any code changes, verify git status.
- Quality gates — Lint → Typecheck → Test before completion.
- Wrap-up audit — Walk the board. Unaccounted cards are broken, re-architected, or requeued.
- Skill self-audit — Invoke
skill-self-audit skill. Repeated processes become skills via boomerang-agent-builder.
- Todo list update — Invoke
todo-list-updater skill for the current phase.
- Save to memory —
memoryManager_add_memory with project tag.
