From c0c8ae041d6461d59f483bddce2e3345c8f9eda0 Mon Sep 17 00:00:00 2001 From: Aurelio <19254254+Aureliolo@users.noreply.github.com> Date: Sun, 8 Mar 2026 18:58:08 +0100 Subject: [PATCH 1/3] feat: implement LLM decomposition strategy and workspace isolation (#168, #133) Add LlmDecompositionStrategy using tool calling for structured LLM output with content fallback and retry loop. Add workspace isolation module with git-worktree-based PlannerWorktreeStrategy, MergeOrchestrator, and WorkspaceIsolationService for concurrent agent execution. --- src/ai_company/core/enums.py | 15 +

<19254254+Aureliolo@users.noreply.github.com> Date: Sun, 8 Mar 2026 19:31:03 +0100 Subject: [PATCH 2/3] fix: address pre-PR review findings for workspace isolation and LLM decomposition MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Pre-reviewed by 9 agents, 42 findings addressed: - Add cross-field model_validator on MergeResult for success/conflicts/SHA consistency - Change Workspace.created_at from str to datetime, MergeResult.escalation to ConflictEscalation enum - Add git ref validation to prevent argument injection via dash-prefixed strings - Fix returncode handling (None → -1), add explicit UTF-8 encoding with error replacement - Serialize merge_workspace and teardown_workspace with asyncio.Lock - Add branch cleanup on worktree creation failure (prevent orphaned branches) - Check merge --abort return code, raise WorkspaceMergeError on failure - Add rollback in setup_group, best-effort teardown in teardown_group - Handle WorkspaceMergeError in merge_all (create failure result vs abort) - Append unmentioned workspaces in _sort_workspaces (prevent silent drops) - Add model validation for blank LLM model string - Add structured logging for conflict collection, enum defaults, validation errors - Use NotBlankStr for worktree_base_dir config field - Update DESIGN_SPEC.md project structure with workspace/ and decomposition files - Update CLAUDE.md engine description, README.md feature list --- CLAUDE.md | 2 +- DESIGN_SPEC.md | 17 +- README.md | 3 +- src/ai_company/core/enums.py | 12 +-

LLM-based decomposition strategies and runtime multi-agent coordination are M4+ (see #168). +> **Current state:** Task structure classification (`TaskStructureClassifier`), DAG-based decomposition (`DecompositionService`, `DependencyGraph`, `ManualDecompositionStrategy`), LLM-based decomposition (`LlmDecompositionStrategy` with tool calling and JSON content fallback), status rollup (`StatusRollup`), agent-task scoring (`AgentTaskScorer`), routing (`TaskRoutingService`), and auto topology selection (`TopologySelector`) are implemented in `engine/decomposition/` and `engine/routing/`. Workspace isolation (`PlannerWorktreeStrategy`, `MergeOrchestrator`, `WorkspaceIsolationService`) is implemented in `engine/workspace/`. Runtime multi-agent coordination is M4+. Empirical research on agent scaling ([Kim et al., 2025](https://arxiv.org/abs/2512.08296) — 180 controlled experiments across 3 LLM families and 4 benchmarks) demonstrates that **task decomposability is the strongest predictor of multi-agent effectiveness** — stronger than team size, model capability, or coordination architecture. @@ -2398,11 +2398,21 @@ ai-company/ │ │ │ ├── __init__.py # Package exports │ │ │ ├── classifier.py # TaskStructureClassifier (sequential/parallel/mixed) │ │ │ ├── dag.py # DependencyGraph (validation, topo sort, parallel groups) +│ │ │ ├── llm.py # LlmDecompositionStrategy (LLM-based decomposition with tool calling) +│ │ │ ├── llm_prompt.py # Prompt building and response parsing for LLM decomposition │ │ │ ├── manual.py # ManualDecompositionStrategy │ │ │ ├── models.py # SubtaskDefinition, DecompositionPlan, DecompositionResult, SubtaskStatusRollup, DecompositionContext │ │ │ ├── protocol.py # DecompositionStrategy protocol │ │ │ ├── rollup.py # StatusRollup (compute subtask status aggregation) │ │ │ └── service.py # DecompositionService (orchestrates strategy + classifier + DAG) +│ │ ├── workspace/ # Workspace isolation subsystem (§6.8) +│ │ │ ├── __init__.py # Package exports +│ │ │ ├── config.py # PlannerWorktreesConfig, WorkspaceIsolationConfig +│ │ │ ├── git_worktree.py # PlannerWorktreeStrategy (git worktree backend) +│ │ │ ├── merge.py # MergeOrchestrator (sequential merge with conflict escalation) +│ │ │ ├── models.py # Workspace, WorkspaceRequest, MergeResult, MergeConflict, WorkspaceGroupResult +│ │ │ ├── protocol.py # WorkspaceIsolationStrategy protocol +│ │ │ └── service.py # WorkspaceIsolationService (lifecycle orchestrator) │ │ ├── routing/ # Task routing subsystem │ │ │ ├── __init__.py # Package exports │ │ │ ├── models.py # RoutingCandidate, RoutingDecision, RoutingResult, AutoTopologyConfig @@ -2501,7 +2511,8 @@ ai-company/ │ │ │ ├── task_assignment.py # TASK_ASSIGNMENT_* constants │ │ │ ├── task_routing.py # TASK_ROUTING_* constants │ │ │ ├── template.py # TEMPLATE_* constants -│ │ │ └── tool.py # TOOL_* constants +│ │ │ ├── tool.py # TOOL_* constants +│ │ │ └── workspace.py # WORKSPACE_* constants │ │ ├── processors.py # Log processors │ │ ├── setup.py # Logging setup │ │ └── sinks.py # Log output backends diff --git a/README.md b/README.md index 0c1019e0b6..1593415434 100644 --- a/README.md +++ b/README.md @@ -16,8 +16,9 @@ AI Company lets you spin up a virtual organization staffed entirely by AI agents - **Smart Cost Management** - Per-agent budget tracking, auto model routing, CFO agent optimization - **Hierarchical Delegation** - Chain-of-command task delegation with five-mechanism loop prevention - **Conflict Resolution** - Pluggable strategies for resolving agent disagreements (authority, debate, human escalation, hybrid) with dissent audit trail -- **Task Decomposition & Routing** - DAG-based subtask decomposition, structure classification, and agent-task scoring +- **Task Decomposition & Routing** - DAG-based and LLM-based subtask decomposition, structure classification, and agent-task scoring - **Task Assignment** - Pluggable strategies (manual, role-based, load-balanced) for matching tasks to capable agents +- **Workspace Isolation** - Git worktree-based concurrent workspace isolation with sequential merge and conflict escalation - **Configurable Autonomy** - From fully autonomous to human-approves-everything, with a Security Ops agent in between - **Persistent Memory** - Agents remember past decisions, code, relationships (memory layer TBD) - **HR System** - Hire, fire, promote agents.
