Coding agents need to dynamically derive concrete, workspace-specific steps from a generic workflow intent (e.g. "verify-build") rather than relying on hardcoded templates. This PR documents how agentloop's machinery performs this intent-to-action transformation and adds the missing workspace exploration and planner context infrastructure to support it.

Research (issues/2.md)

Completely rewritten to focus on the dynamic agent-driven transformation from generic intent to concrete steps:

  • Shows the new transformation pipeline: ProjectExplorer.exploreWorkspace()generatePlan()executePlan() — the explorer reads actual project files via LLM+tools and the planner derives steps from the resulting context at runtime
  • Identifies which interaction patterns from the baseline research (copilot/research-agent-fws) are essential:
    • Plan-Execute-Verify loop (Issue 3) — Critical: the word "verify" in "verify-build" requires a verification step; without it the orchestrator cannot distinguish a successful build from a failed one
    • Dynamic Task Decomposition (Issue 4) — Important: handles mid-execution surprises (missing deps, uninitialized submodules) by injecting sub-steps at runtime without a full replan
    • Hierarchical Delegation (Issue 4) — Architectural → Partially Implemented: ProjectExplorer is the workspace-analyst child agent; coordinatedExecute() now accepts WorkspaceContext
    • Toolbox Refiner (Issue 5) — Supporting: narrows the tool set to what the build agent actually needs

ProjectExplorer agent (src/agents/project-explorer.ts)

New exploreWorkspace({ registry, llm }) function runs a project-explorer subagent with file-list and file-read tools:

  1. Lists the root directory tree to understand project layout
  2. Identifies and reads all key manifest/configuration files (CMakeLists.txt, CMakePresets.json, Cargo.toml, build.gradle, pom.xml, go.mod, etc.)
  3. Reasons from file contents to identify all build systems — a single project may have more than one

No hardcoded command strings: the LLM reads the actual files and derives build system information from their contents. If cmake is not on PATH, the notes reflect that; the executing agent resolves the invocation for the target platform.

WorkspaceContext (src/workspace.ts)

New WorkspaceContext interface — a generic map that flows through the planning pipeline:

interface WorkspaceContext extends Record<string, unknown> {
  workspaceInfo: WorkspaceInfo;          // flat summary for backward compatibility
  buildSystems?: BuildSystemInfo[];      // one entry per detected build system
  explorerNotes?: string;               // free-form observations (e.g. monorepo layout)
}

toWorkspaceContext(info: WorkspaceInfo) wraps the existing analyzeWorkspace() result for backward-compatible use in the plan and plan-and-run tools.

Planner context (src/subagents/planner.ts)

generatePlan() and refinePlan() now accept WorkspaceContext instead of WorkspaceInfo. buildPlannerTask includes buildSystems[].notes and explorerNotes in the planner prompt so the LLM derives concrete commands from actual file content:

Detected build systems:
  - cmake (CMakeLists.txt): CMakePresets.json present. Use preset 'linux-release' for release builds.

Coordinator (src/agents/coordinator.ts)

CoordinatedExecuteOptions.workspaceContext: WorkspaceContext replaces the former workspaceInfo: WorkspaceInfo field, making the high-level entry point compatible with ProjectExplorer output.

Workflow execution primitives

Two new agent profiles + one generic skill shape the execution environment for build and test steps. The concrete commands always come from workspace exploration, not from the profiles:

File Role
build-verify.agent.json Low-temperature build agent; binds shell, file-read, file-list
test-runner.agent.json Test execution agent; binds editing tools for fix-and-rerun cycles
build-verify.skill.md Domain guidance: how to identify the build system, interpret output, triage errors

Copilot misunderstood my intention.
I want to have the machine to derive concrete steps from a generic task defined by "intention". Deriving can be done by using an agent itself, I don't want to hardcode cmake profiles.
take "verify-build" (defined by intention) in a generic dev workflow.
when the agent works there should be a step in the machinery that transforms the generic intention into actionable steps suitable for the workspace.
there could be an agent, that is able to transform a generic intent into the actionable, concrete plan.
only reason about the possibilities, workflows, interaction patterns in the components like planner and orchestrator.
MUST: look in the referenced branch an show which interaction patterns for the machinery described there, are essential for success

Addressed in 3e615c9. The research document (issues/2.md) has been completely rewritten to reason about the dynamic agent-driven transformation from generic intent ("verify-build") to concrete workspace-specific steps.

Key points in the revised document:

  1. The transformation pipeline — shows exactly where in the machinery the transformation happens: analyzeWorkspace() detects the build system and extracts lifecycle commands → generatePlan() / buildPlannerTask() injects that workspace context into the planner LLM which reasons intent + workspace → concrete PlanStep[] → orchestrator activates per-step agent profiles.

  2. Which interaction patterns from the baseline research (copilot/research-agent-fws) are essential:

    • Plan-Execute-Verify loop (Issue 3) — Critical: Without the verification step, "verify-build" only runs the build, it doesn't verify the outcome. The PEV loop is what closes this gap, including dynamic replanning when the verifier flags a failure.
    • Dynamic Task Decomposition (Issue 4) — Important: When execution reveals surprises (missing submodules, wrong deps), the decompose_task tool allows mid-execution step injection without replanning from scratch.
    • Hierarchical Delegation (Issue 4) — Architectural: A coordinator can delegate workspace probing to a child agent, enabling active workspace analysis rather than relying solely on pre-computed WorkspaceInfo.
    • Toolbox Refiner (Issue 5) — Supporting: Narrows the tool set to what the build agent actually needs.
  3. No hardcoded cmake commands — the cmake-specific skill has been removed. Concrete commands come from analyzeWorkspace() at runtime, injected into the planner as workspace context.

The workspaceinfo still uses hardcoded exploration for cargo, cmake by using cmd lines, which in case of cmake on windows could be not on the path.
Goal I want to have a ProjectExplorer Agent, which itself can consist of a bunch of subagents.
The ProjektExplorer explores by using a prompt a.) Directory structure, b.) Key files and c.) build systems (one project could have more than one). You decide about which order these steps make sense or whether they can land in a single prompt.
the output can be feed into planner. But it should in a generic way, like we have a Context map, which can hold a WorkspaceInfo

Addressed in 000a8ae.

The hardcoded workspace analysis for CMake, Cargo, Gradle, and Maven has been replaced by the ProjectExplorer agent (src/agents/project-explorer.ts).

How it works:

  • exploreWorkspace({ registry, llm }) runs a project-explorer subagent with access to the file-list and file-read tools
  • The LLM explores: a) directory structure via file-list (recursive), b) key manifest files via file-read (CMakeLists.txt, CMakePresets.json, Cargo.toml, build.gradle, pom.xml, etc.), c) all detected build systems — a single project can have more than one
  • No hardcoded command strings anywhere — the LLM reads the actual files and reasons about the right invocation

The output — WorkspaceContext — is a generic map added to src/workspace.ts:

interface WorkspaceContext extends Record<string, unknown> {
  workspaceInfo: WorkspaceInfo;
  // explorer-contributed keys:
  buildSystems?: BuildSystemInfo[];  // one per detected build system
  explorerNotes?: string;            // free-form observations (e.g. monorepo layout)
}

This flows through the entire pipeline: generatePlan(), refinePlan(), and coordinatedExecute() all accept WorkspaceContext. The planner task includes buildSystems[].notes so the planner LLM derives concrete commands from the project's own files, not from hardcoded heuristics.

The old analyzeWorkspace() remains as a fast fallback (Node/Python/Go) wrapped with toWorkspaceContext() in the plan and plan-and-run tools.
