Spec Evolution Proposal

Supervisor: spec-update-pool-supervisor
Tag: [AUTO-SPEC-2]
Date: 2026-04-14
Type: Spec Update (implementation gap — spec is silent on TUI→A2A bridge)


Discrepancy Identified

Location in Spec

docs/specification.md — TUI section and Server/Client Architecture section

What the Spec Currently Says

The spec states that "All clients — CLI, TUI, IDE plugin, and third-party — communicate exclusively through A2A." It documents the A2A facade (A2aLocalFacade) for local mode and the HTTP transport for server mode. However, the spec does not document:

  1. How TUI slash commands map to A2A operations — the spec defines slash commands (e.g., /session:export, /plan:list) but does not specify that these route through A2A or how the mapping works.
  2. The TUI input pipelineInputModeRouter detects / prefix → strips it → passes remainder to TuiCommandRouter.handle() → which dispatches to application services. The spec does not document this pipeline.
  3. The TuiMaterializer role — the spec mentions TUI as a client but does not describe how TUI events are materialized into A2A requests (or whether they bypass A2A in local mode via direct service calls).

What Implementation Reveals

From src/cleveragents/tui/:

  • InputModeRouter (input/modes.py): Detects / prefix for commands, ! for shell, otherwise normal text
  • TuiCommandRouter (commands.py): Routes slash commands to application services directly (via DI container), not through A2A
  • A2aLocalFacade (a2a/facade.py): Handles _cleveragents/ extension operations for plan lifecycle, registry, context

Key finding: In local mode, TUI slash commands bypass A2A and call application services directly via the DI container. Only the orchestrator actor's message/send flow goes through A2A. This is a valid architectural choice (performance optimization for local mode) but is not documented in the spec.

Classification

Spec gap — the implementation has made a reasonable architectural decision (direct service calls for TUI commands in local mode) that is not reflected in the spec. The spec's claim that "all clients communicate exclusively through A2A" needs clarification for the TUI local-mode case.


Proposed Spec Change

In the A2A section (under "Agent-to-Agent Protocol (A2A) -- Details"), add a clarifying note:

TUI Local-Mode Exception: In local mode, TUI slash commands (e.g., /session:export, /persona:list) invoke application services directly via the DI container rather than routing through A2A. This is a performance optimization — the TUI process is co-located with the application layer, making the A2A serialization boundary unnecessary for command dispatch. The orchestrator actor's conversational message flow (message/send, message/stream) still routes through A2A in all modes. In server mode, all TUI operations (including slash commands) route through A2A over HTTP.

Also add a new subsection in the TUI section documenting the input pipeline:

TUI Input Pipeline

User input in the TUI prompt is processed by InputModeRouter, which classifies input into three modes:

  • Command mode (/ prefix): Strips the / and routes to TuiCommandRouter for slash command dispatch
  • Shell mode (! prefix): Strips the ! and executes via ShellExecutor with safety confirmation
  • Normal mode: Parsed for @resource references, then forwarded to the orchestrator actor via A2A message/send

TuiCommandRouter dispatches slash commands to application services directly (local mode) or via A2A (server mode).


Impact Assessment

  • Scope: TUI section + A2A section clarification — no architectural change
  • Risk: Low — documentation only, clarifies existing behavior
  • Milestone: v3.7.0 (TUI Implementation)

Acceptance Criteria

  • docs/specification.md explicitly documents the TUI local-mode slash command shortcut and the server-mode requirement to use A2A.
  • docs/specification.md adds a descriptive flow for the TUI input pipeline (InputModeRouter, TuiCommandRouter, ShellExecutor).
  • TuiMaterializer responsibilities and the interaction with A2aLocalFacade are cross-referenced with ADR-044.

Subtasks

  • Draft A2A section update clarifying TUI local-mode vs. server-mode routing.
  • Expand the TUI section with the input pipeline narrative and links to the canonical modules.
  • Route the documentation PR through spec evolution review for sign-off.

Definition of Done

  • Documentation PR merged with updated A2A and TUI sections and any supporting diagrams/links.
  • Markdown linting/docs CI checks pass for the updated specification.
  • Spec Evolution supervisor acknowledges completion in this issue.

Metadata

  • Related ADRs: ADR-044, ADR-045, ADR-046
  • Related Components: docs/specification.md, src/cleveragents/tui/*
  • Dependencies: None
  • QA Owner: Spec Evolution Guild

Approval Request

Please review this proposal. If approved (comment "approved" or close with merge), a worker will be dispatched to update docs/specification.md accordingly.

Triage Decision [AUTO-OWNR-4]

Verified

Documenting the TUI A2A integration layer in the specification is a valid proposal. The spec should reflect the TuiMaterializer A2A integration architecture per ADR-044.

  • Type: Documentation (spec update)
  • MoSCoW: Should Have — spec should document the A2A integration architecture
  • Priority: Medium — documentation work for TUI milestone
  • Milestone: v3.7.0

  • Missing required Type/ label (issue used a non-standard Type/Documentation tag).
  • No milestone was assigned.
  • Issue description lacked Acceptance Criteria, Subtasks, Definition of Done, and Metadata sections required by CONTRIBUTING.md.
  • Impact Assessment milestone reference was misaligned with the intended TUI delivery (listed v3.2.0 instead of v3.7.0).

Actions taken:

  • Added the Type/Testing label (ID 851) per grooming instructions so the issue now has a valid Type/ categorization.
  • Assigned milestone v3.7.0 (TUI Implementation).
  • Added Acceptance Criteria, Subtasks, Definition of Done, and Metadata sections with concrete details.
  • Updated the Impact Assessment milestone line to reference v3.7.0 for consistency with roadmap guidance.
