# Functional Block Agent Context

Keep this file focused on the local contract for this primary functional block.

<!-- BEGIN CAPABILITY CONTEXT -->

## Capability Context

- Capability ID: `runtime-harness-agent-runtime-effects`

- Domain: `runtime-harness`

- Name: `agent-runtime-effects`

- Primary prefix: `src/core/engineers/agent-runtime-effect.ts`

- Architecture module: `docs/architecture/modules/runtime-harness/agent-runtime-effects.md`

- Workstream: `tasks/workstreams/runtime-harness/agent-runtime-effects`

## Positioning

Owns the runtime-harness-agent-runtime-effects capability boundary declared in .archcontext/model/nodes.

## Source Map

- Primary prefix: `src/core/engineers/agent-runtime-effect.ts` (entrypoint)

- Architecture module: `docs/architecture/modules/runtime-harness/agent-runtime-effects.md` (design-source)

- Workstream: `tasks/workstreams/runtime-harness/agent-runtime-effects` (durable-progress)

## Refresh Hints

- `bun test tests/unit/r1-provider-neutral-agent-runtime.test.ts tests/unit/r1-agent-runtime-adapters.test.ts tests/unit/issue-281-task-offer-wake.test.ts tests/cli/engineer.test.ts tests/cli/mcp-engineer-tools.test.ts --timeout 60000`

- `bun run check:type`

<!-- END CAPABILITY CONTEXT -->

<!-- BEGIN ARCHITECTURE CONTRACT -->

## Architecture Contract

- Functional block: `src/effects/engineers/agent-runtime-adapters`

- Capability ID: `runtime-harness-agent-runtime-effects`

- Matched prefix: `src/effects/engineers/agent-runtime-adapters`

- Architecture domain: `runtime-harness`

- Architecture capability: `agent-runtime-effects`

- Architecture module: `docs/architecture/modules/runtime-harness/agent-runtime-effects.md`

- Last architecture event: 2026-09-09T02:02:06+0800

- Last changed path: `src/effects/engineers/agent-runtime-adapters/herdr-cli-agent.ts`

- Severity: low

- Change type: source-change

- Module responsibility: Keep this block aligned with the local boundary described by surrounding human-owned context.

- Entrypoints: `src/effects/engineers/agent-runtime-adapters`

- Allowed dependencies: Follow root `AGENTS.md` / `CLAUDE.md` and this local contract.

- Forbidden dependencies: Do not cross sibling app/service/package boundaries without an architecture snapshot or explicit plan.

- Runtime path: `src/effects/engineers/agent-runtime-adapters`

- LSP/tooling profile: `typescript-lsp`

- Verification: Use root required checks plus local commands recorded in this capability contract.

- Latest snapshot: `(none yet)`

- Semantic diagram source: `docs/architecture/modules/runtime-harness/agent-runtime-effects.md`

## Active Workstreams

- `tasks/workstreams/runtime-harness/agent-runtime-effects/me3a-provider-thread-effect.md`

- status: completed

- current_slice: completed-20260825-me3a-provider-thread-effect

- source_plan: plans/plan-20260825-2120-me3a-provider-thread-effect.md

- `tasks/workstreams/runtime-harness/agent-runtime-effects/r1-provider-neutral-agent-runtime.md`

- status: completed

- current_slice: completed-20260831-r1 (PR #230, squash 4f7cb37e)

- source_plan: plans/plan-20260830-1903-r1-provider-neutral-agent-runtime.md

## Current Session Projection

- Durable progress lives under `tasks/workstreams/runtime-harness/agent-runtime-effects`.

- `tasks/current.md` is the ignored local derived status read model; it is not a live lock or task source.

- `tasks/todos.md` is the deferred-goal ledger; current execution slices stay in the active plan's `## Task Breakdown`.
