Summary

Implement the tools.expand TUI setting per the specification (§ Conversation Block Details > Tool Call States). This adds the ToolCallBlock presentation model with a 4-state visual state machine (pending, completed-collapsed, completed-expanded, failed) controlled by a 5-value ToolExpandMode enum (never, always, success, fail, both).

Closes #1000

Changes

New Module: src/cleveragents/tui/widgets/tool_call_block.py

  • ToolExpandMode (StrEnum): 5 values — never, always, success, fail (default), both — matching the specification's tools.expand choices setting.
  • ToolCallState (StrEnum): 4 visual states — pending, completed_collapsed, completed_expanded, failed.
  • ToolCallSetting (frozen @dataclass): Schema descriptor for the tools.expand setting (key, type, default, choices, description).
  • should_auto_expand(): Pure decision function that evaluates expand mode, success/failure status, and tool kind. Implements the kind: "read" suppression rule (read-kind tool calls never auto-expand regardless of mode). Kind matching is case-sensitive and exact ("read" only). Includes explicit exhaustiveness guard (ValueError for unhandled modes) to catch future enum additions.
  • ToolCallBlock (@dataclass): Presentation model with complete(), fail(), and toggle() state-transition methods, plus indicator, chevron, is_expanded, is_failed, render_header(), and render() rendering helpers. Not thread-safe; intended for single-threaded (UI-thread) use only.

Key Design Decisions

Outcome tracked independently from visual state: The _succeeded: bool | None field (excluded from __init__ via init=False) tracks the success/failure outcome independently from the expand/collapse visual state (ToolCallState). This ensures that:

  • The indicator property always shows the correct symbol (✔ for success, ✗ failed for failure) regardless of whether the block is expanded or collapsed.
  • Toggling a failed block between expanded and collapsed states never loses the failure identity.
  • The is_failed property provides a programmatic way for callers to distinguish success content from error content in result_content.

Toggle restores FAILED state: When an expanded failed block is toggled closed, it transitions back to ToolCallState.FAILED (not COMPLETED_COLLAPSED), preserving the correct state for downstream code that checks block.state == ToolCallState.FAILED.

Defensive indicator guard: If _succeeded is None for a non-PENDING block (unreachable via normal API), indicator returns the pending symbol instead of incorrectly showing success.

Exhaustive mode handling: should_auto_expand() explicitly checks each ToolExpandMode member and raises ValueError for any unhandled mode. This ensures that adding a 6th enum member in the future will produce a clear error instead of silently inheriting fallback behavior.

Spec interpretation — "Failed (expanded)": The specification mockup shows only 4 visual states (Failed is always collapsed), but the behaviour table requires auto-expanded failures. We reuse COMPLETED_EXPANDED with _succeeded=False to represent this state; an inline comment documents this extrapolation.

Updated: src/cleveragents/tui/widgets/__init__.py

  • Exports all new public types and constants from tool_call_block.

Updated: CHANGELOG.md

  • Added entry under ## Unreleased documenting the new ToolCallBlock widget and tools.expand setting with 5 expand modes.

Tests

  • Behave (features/tui_tool_call_block.feature): 60 scenarios covering all 5 expand modes with indicator/chevron assertions, kind: "read" suppression (all 10 mode×outcome combinations), case-sensitive kind matching boundaries, manual toggle with full round-trip (including FAILED→expand→collapse), multi-toggle round-trip preservation of indicators, is_failed property, error handling (including fail→complete and fail→fail transitions), argument validation, rendering (including expanded failed block error content and render-after-toggle), and empty content edge cases. Tagged with @tui @tool_call_block for filtering.
  • Robot (robot/tui_tool_call_block.robot): 3 integration tests verifying end-to-end lifecycle (including toggle restoration of FAILED state), five-mode expand behavior, and render output correctness (including auto-expanded failed block error content in render). Uses common.resource with standard Suite Setup/Suite Teardown for pabot isolation. All test cases tagged with tui and tool_call_block.

Deferred Items

  • ToolCallSetting not registered in settings system: ToolCallSetting is a schema descriptor awaiting future settings infrastructure. No settings registry exists yet.
  • Unbounded result_content: No size limit on stored content. Callers are responsible for truncating large content before passing to complete()/fail(). (Tracked by TODO comment in code.)
  • Rich markup injection: render_header() and render() embed user-controlled content verbatim. Rich markup escaping should be added when Textual/Rich integration is implemented. (Tracked by TODO comments in code.)
  • Robot tests at unit level: Current Robot tests exercise unit-level assertions. True integration scenarios should be added when the TUI rendering layer is implemented.

Motivation

The TUI specification defines tool call visual states and auto-expand behavior but no implementation existed. This PR provides the core expand-mode logic and presentation model needed by the conversation block rendering layer.

## Summary Implement the `tools.expand` TUI setting per the specification (§ Conversation Block Details > Tool Call States). This adds the `ToolCallBlock` presentation model with a 4-state visual state machine (pending, completed-collapsed, completed-expanded, failed) controlled by a 5-value `ToolExpandMode` enum (`never`, `always`, `success`, `fail`, `both`).

Implement the tools.expand TUI setting per the specification
(§ Conversation Block Details > Tool Call States).  The new
ToolCallBlock presentation model supports a 4-state visual
state machine (pending, completed-collapsed, completed-expanded,
failed) driven by a 5-value ToolExpandMode enum (never, always,
success, fail, both).

Key design decisions:
- ToolExpandMode (StrEnum) with default FAIL, matching the
  specification choices setting (type: choices, default: fail).
- ToolCallSetting frozen dataclass captures the schema descriptor
  for tools.expand (key, type, default, choices, description).
- should_auto_expand() pure function encapsulates the expand
  decision logic, including kind:"read" suppression (read-kind
  tool calls never auto-expand regardless of mode).
- ToolCallBlock dataclass manages state transitions via
  complete(), fail(), and toggle() methods with strict argument
  validation and state guards.
- Rendering helpers (indicator, chevron, render_header, render)
  produce the specification visual indicators.

Tests:
- 38 Behave scenarios covering all 5 modes, read suppression,
  manual toggle, error handling, and rendering.
- 3 Robot integration tests verifying end-to-end lifecycle,
  five-mode behavior, and render output correctness.
- Overall coverage: 97%, tool_call_block.py at 100%.

Code Review — PR #1219: feat(tui): implement tool call expand states (5 modes)

Verdict: ✅ APPROVED (code quality) — ⚠️ BLOCKED on merge conflicts

Specification Alignment ✅

The implementation faithfully matches issue #1000's requirements:

  • All 5 ToolExpandMode values (never, always, success, fail, both) implemented correctly
  • 4 visual states (pending, completed_collapsed, completed_expanded, failed) with correct state machine transitions
  • kind: "read" suppression rule: case-sensitive exact match, never auto-expands regardless of mode
  • Manual toggle works on any non-pending block with correct round-trip behavior
  • Default mode is fail as specified
  • ToolCallSetting schema descriptor correctly defines the tools.expand setting

Code Quality ✅

Production code (tool_call_block.py, 336 lines):

  • Zero # type: ignore suppressions — fully statically typed
  • Clean module structure with well-separated concerns (enums → constants → setting → logic → model)
  • Proper fail-fast argument validation with TypeError/ValueError in all public methods
  • Exhaustive ToolExpandMode handling with ValueError guard for future enum additions
  • Independent outcome tracking (_succeeded: bool | None) from visual state — elegant design that preserves failure identity across toggle operations
  • Defensive indicator guard for unreachable _succeeded is None on non-PENDING blocks
  • Appropriate TODO comments for deferred items (content truncation, Rich markup escaping)
  • Under 500-line file limit
  • from __future__ import annotations at top
  • @dataclass(slots=True) for performance; frozen=True on immutable ToolCallSetting

Design decisions are well-documented:

  • Toggle restoring FAILED state (not COMPLETED_COLLAPSED) for failed blocks
  • BOTH vs ALWAYS semantic distinction for future extension
  • Spec interpretation for "failed but expanded" state using COMPLETED_EXPANDED + _succeeded=False

Test Quality ✅

Behave (60 scenarios, features/tui_tool_call_block.feature):

  • All 5 expand modes tested for both success and failure outcomes (10 scenarios)
  • All 10 kind: "read" × mode combinations tested exhaustively
  • Case-sensitive kind matching boundary cases (3 scenarios: "Read", "READ", "read ")
  • Manual toggle with full round-trip including FAILED→expand→collapse
  • Multi-toggle preservation of indicators for both success and failure
  • Error handling: complete/fail on non-pending, toggle on pending, fail→complete, fail→fail
  • Argument validation: TypeError for bad types on should_auto_expand, complete(), fail()
  • Rendering: header content, expanded/collapsed content visibility, error content in expanded failed blocks
  • Edge cases: empty result/error strings
  • Properly tagged @tui @tool_call_block

Robot (3 integration tests, robot/tui_tool_call_block.robot):

  • Integration smoke test covering full lifecycle with toggle round-trip
  • Five-mode expand behavior verification including read suppression across all modes
  • Render output correctness with indicator/chevron assertions
  • Uses common.resource with standard Suite Setup/Suite Teardown
  • Tagged tui and tool_call_block

PR Hygiene ✅

  • Conventional Changelog commit message format
  • Closes #1000 in PR body
  • Milestone v3.7.0 assigned (matches issue)
  • Type/Feature label present
  • CHANGELOG.md updated under ## Unreleased
  • Quality gates reported as passing (lint, typecheck, unit_tests, integration_tests, coverage at 97%+)

⚠️ Merge Blocked: Rebase Required

The PR has merge conflicts (mergeable: false) due to changes on master since the branch was created:

  1. src/cleveragents/tui/widgets/__init__.py: Master now includes HelpPanelOverlay (from feat(tui): implement help panel (F1)), which the PR branch is missing.
  2. CHANGELOG.md: Multiple entries added to ## Unreleased on master since the branch diverged.

Action needed: Rebase feature/m8-tui-tool-call-expand onto current master, resolve the conflicts (add HelpPanelOverlay import alongside the new tool_call_block imports, and merge CHANGELOG entries), then force-push. Once conflicts are resolved and CI passes, this PR can be merged.

Code Review — PR #1219: feat(tui): implement tool call expand states (5 modes)

Verdict: ✅ APPROVED

Specification Alignment ✅

The implementation faithfully satisfies all acceptance criteria from issue #1000:

  • All 5 ToolExpandMode values (never, always, success, fail, both) implemented correctly
  • 4 visual states (pending, completed_collapsed, completed_expanded, failed) with correct state machine transitions
  • kind: "read" suppression rule: case-sensitive exact match, never auto-expands regardless of mode
  • Manual toggle works on any non-pending block with correct round-trip behavior (including FAILED → expanded → FAILED preservation)
  • Default mode is fail as specified
  • ToolCallSetting schema descriptor correctly defines the tools.expand setting

Code Quality ✅

Production code (tool_call_block.py, 336 lines):

  • Zero # type: ignore suppressions in production code — fully statically typed
  • Clean module structure: enums → constants → setting → logic → model
  • Proper fail-fast argument validation with TypeError/ValueError in all public methods
  • Exhaustive ToolExpandMode handling with ValueError guard for future enum additions
  • Independent outcome tracking (_succeeded: bool | None) from visual state — elegant design that preserves failure identity across toggle operations
  • Defensive indicator guard for unreachable _succeeded is None on non-PENDING blocks
  • Appropriate TODO comments for deferred items (content truncation, Rich markup escaping)
  • Under 500-line limit, from __future__ import annotations at top, @dataclass(slots=True) for performance
  • Well-documented design decisions (toggle restoring FAILED state, BOTH vs ALWAYS distinction, spec interpretation for expanded-failed state)

Test Quality ✅

Behave (60 scenarios): Exhaustive coverage of all 5 modes × success/failure, all 10 kind: "read" combinations, case-sensitive kind matching boundaries (3 edge cases), manual toggle round-trips, multi-toggle indicator preservation, error handling (complete/fail on non-pending, toggle on pending), argument validation (TypeError for bad types), rendering (header/content visibility, expanded failed error content), and empty content edge cases. Properly tagged @tui @tool_call_block.

Robot (3 integration tests): Full lifecycle smoke test with toggle round-trip, five-mode expand behavior verification including read suppression, and render output correctness with indicator/chevron assertions. Uses common.resource with standard Suite Setup/Suite Teardown.

Correctness ✅

No logic errors found. Key correctness points verified:

  • toggle() correctly transitions COMPLETED_EXPANDED → FAILED when _succeeded is False
  • indicator property correctly reflects outcome (not visual state) across all toggle states
  • chevron property correctly reflects expand/collapse state regardless of success/failure
  • should_auto_expand() mode evaluation order is correct (each mode checked independently)

PR Hygiene ✅

  • Conventional Changelog commit message format
  • Closes #1000 in PR body
  • Milestone v3.7.0 assigned (matches issue)
  • Type/Feature label present
  • CHANGELOG.md updated under ## Unreleased
  • __init__.py exports sorted alphabetically (RUF022), rebase conflicts resolved correctly
  • Quality gates passing (lint, typecheck, unit_tests — 60 scenarios, 0 failed)

Security ✅

No secrets, no injection vulnerabilities. TODO comments appropriately track Rich markup escaping for future integration.

Proceeding to merge.

🤖 Backlog Groomer (groomer-1) — Duplicate Detected

This PR (#1219) is a duplicate of the canonical tracking issue #1000 ("feat(tui): implement tool call expand states (5 modes)").

Rationale:

  • #1000 is the original tracking issue with full metadata: MoSCoW label, Points, Priority, State/In Review, parent link to #868, and dependency tracking via #926.
  • This PR (#1219) was opened later and its body explicitly states Closes #1000, confirming it is the implementation PR for that tracking issue.
  • The PR itself is not a separate work item — it is the delivery vehicle for #1000.

Action: Closing this issue as a duplicate of #1000. All tracking, review, and merge activity should be associated with #1000.

auto/last-attempt-tier-min
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

  
Automation Tracking
Tracking issues used by the AI Automation system for agents to communicate and report.

auto/restart-throttled
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

  
auto/revert
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

  
auto/sentinel
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

  
auto/stale-inactivity
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.

  
auto/unstable
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
