Summary

Fix CI failures on main: 2 test assertion mismatches in cost-optimized assignment tests + mypy attr-defined error in strategy registry test
Address all Greptile post-merge review findings across PRs fix: address post-merge review feedback from PRs #164-#167 #170–feat: add cost-optimized, hierarchical, and auction assignment strategies #175 (14 fixes total)

PR #175 — Test assertion fixes (CI blockers)

"no cost data" → "insufficient cost data" to match implementation wording
unknown-dev → known-dev winner assertion (all-or-nothing fallback, sort stability)
getattr() for _scorer access on protocol type (Windows/Linux mypy difference)

PR #174 — Workspace isolation

_validate_git_ref raises context-appropriate exception types (WorkspaceMergeError in merge, WorkspaceCleanupError in teardown)
_run_git catches asyncio.CancelledError to kill subprocess before re-raising (prevents orphaned git processes)

PR #172 — Task assignment

TaskAssignmentConfig.strategy validated against 6 known strategy names
max_concurrent_tasks_per_agent enforced via new AssignmentRequest.max_concurrent_tasks field in _score_and_filter_candidates
TaskAssignmentStrategy protocol docstring documents error signaling contract (raises vs selected=None)

PR #171 — Worktree skill

rebase uses --left-right --count with triple-dot to detect behind-main worktrees
setup reuse path uses git worktree add without -b for existing branches
setup handles dirty working tree with stash/abort prompt
status table shows both ahead and behind counts
tree provides circular dependency recovery guidance

PR #170 — Meeting parsing

assigned? → assigned regex fix (prevents false-positive assignee extraction from "assign to X")

Test plan

All 3988 tests pass (10 new tests added)
mypy strict: 0 errors (463 source files)
ruff lint + format: all clean
Coverage: 96.53% (threshold: 80%)
Pre-commit hooks pass

🤖 Generated with Claude Code

…resolve mypy attr-defined Tests in test_cost_optimized_assignment.py were written against old "default-missing-to-0.0" semantics but the implementation uses all-or-nothing fallback. Also fix mypy error on CI where protocol type doesn't expose _scorer attribute.

PR #174 — git_worktree.py: - _validate_git_ref now accepts error_cls/event params so merge context raises WorkspaceMergeError and teardown raises WorkspaceCleanupError - _run_git catches asyncio.CancelledError to kill subprocess before re-raising, preventing orphaned git processes PR #172 — task assignment: - TaskAssignmentConfig.strategy validated against known strategy names - max_concurrent_tasks_per_agent now enforced in _score_and_filter_candidates via new AssignmentRequest.max_concurrent_tasks field - TaskAssignmentStrategy protocol docstring documents error signaling contract PR #171 — worktree skill: - rebase uses --left-right --count with triple-dot to detect behind-main - setup reuse path uses correct git worktree add (without -b) - setup handles dirty working tree with stash/abort prompt - status table shows both ahead and behind counts - tree command provides circular dependency recovery guidance PR #170 — meeting parsing: - Fix assigned? regex to assigned (prevents false-positive assignee extraction from "assign to X" in action item descriptions)

📝 Walkthrough

Summary by CodeRabbit

New Features
- Config validation for assignment strategies and support for max_concurrent_tasks to limit concurrent tasks per agent.
- Capacity-aware assignment filtering and more deterministic ordering; status now reports precise ahead/behind counts.
Bug Fixes
- Safer handling of dirty working trees, rebase/conflict flows, and clearer prompts for stash/abort/rebase choices.
- Stricter assignee parsing to require explicit "assigned" phrasing.
Documentation
- Updated design spec clarifying assignment, error semantics, and workspace behaviors.
Tests
- Added unit tests covering capacity, parsing, git ref contexts, and cancellation handling.

Walkthrough

Adds capacity-aware task assignment and strategy-name validation; tightens meeting-assignee parsing and event logging; generalizes git worktree validation and git subprocess handling to use context-specific error types and log events; updates tests and worktree documentation to reflect dual-number ahead/behind semantics and new flows.

Changes

Cohort / File(s)	Summary
Task Assignment Config & Validation `src/ai_company/config/schema.py`, `tests/unit/config/test_schema.py`, `tests/unit/config/conftest.py`	Introduced known strategy set and a validator to reject unknown assignment strategies; added TaskAssignmentConfig to test fixtures and tests for valid/invalid strategy names.
Assignment Models & Protocol `src/ai_company/engine/assignment/models.py`, `src/ai_company/engine/assignment/protocol.py`	Added optional `max_concurrent_tasks` to AssignmentRequest; documented explicit error/return semantics for manual vs. scoring strategies (NoEligibleAgentError vs. AssignmentResult.selected=None).
Capacity-Aware Scoring & Strategies `src/ai_company/engine/assignment/strategies.py`, `tests/unit/engine/test_assignment_strategies.py`, `tests/unit/engine/test_cost_optimized_assignment.py`, `tests/unit/engine/test_strategy_registry.py`	Filters candidates at/above `max_concurrent_tasks` using workload data, logs filtering reasons, preserves deterministic ordering when data is complete, and updates tests to cover capacity and incomplete-cost-data fallbacks; made scorer lookup robust.
Git Worktree: validation, run, merge, teardown `src/ai_company/engine/workspace/git_worktree.py`, `tests/unit/engine/test_workspace_git_worktree.py`, `.claude/skills/worktree/SKILL.md`	Generalized `_validate_git_ref` to accept context-specific error classes and events; added `log_event` and cancellation (CancelledError) handling to `_run_git`; wired context-specific events/errors through setup/merge/teardown flows; updated tests and worktree spec to reflect dirty-state prompts and dual-number ahead/behind logic.
Meeting parsing & observability `src/ai_company/communication/meeting/_parsing.py`, `src/ai_company/observability/events/meeting.py`, `tests/unit/communication/meeting/test_parsing.py`	Added `MEETING_PARSING_NO_SECTION` event constant and tightened assignee regex to require the exact "assigned" form; replaced literal log keys with the new constant and added a test ensuring "assign to" (without "assigned") does not extract an assignee.
Design doc `DESIGN_SPEC.md`	Updated design notes to document assignment config validation, capacity-aware filtering, explicit error signaling for assignment strategies, and context-aware git_worktree error/log behavior.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing the stability and reliability of the system by resolving critical CI failures and addressing a comprehensive list of post-merge review findings. The changes span across various modules, improving git worktree management, refining task assignment logic with better validation and capacity enforcement, and bolstering workspace isolation. The overall impact is a more robust and predictable system behavior, particularly in areas involving git operations and agent task assignments.

Highlights

CI Stability: Resolved two test assertion mismatches in cost-optimized assignment tests and a mypy attr-defined error in the strategy registry test, fixing CI failures on main.
Greptile Review Findings: Addressed 14 post-merge review findings from previous PRs (fix: address post-merge review feedback from PRs #164-#167 #170–feat: add cost-optimized, hierarchical, and auction assignment strategies #175) to improve code quality and robustness.
Worktree Skill Enhancements: Improved git worktree operations, including better handling of dirty working trees during setup, explicit git worktree add for new vs. existing branches, enhanced rebase logic using --left-right --count for behind-main detection, and a more informative status table showing both ahead and behind counts.
Task Assignment Strategy Validation: Implemented validation for TaskAssignmentConfig.strategy against a set of known strategy names and enforced max_concurrent_tasks_per_agent via a new AssignmentRequest.max_concurrent_tasks field, filtering out agents at capacity.
Workspace Isolation Improvements: Updated _validate_git_ref to raise context-appropriate exception types (WorkspaceMergeError, WorkspaceCleanupError) and added asyncio.CancelledError handling to _run_git to prevent orphaned git processes.
Meeting Parsing Fix: Corrected the regex for assignee extraction in meeting parsing to prevent false positives from phrases like 'assign to X'.
Circular Dependency Guidance: Enhanced the tree command to report circular dependencies with cycle details and suggest recovery actions.

Changelog

.claude/skills/worktree/SKILL.md
- Updated setup instructions to handle dirty working trees during git checkout main by prompting to stash or abort.
- Clarified git worktree add usage for new branches versus reusing existing ones, explicitly noting the -b flag's behavior.
- Modified the status table description to include both 'ahead' and 'behind' counts relative to main.
- Enhanced circular dependency error messages in the tree section with cycle reporting and recovery guidance.
- Revised rebase instructions to use git rev-list --left-right --count main...<branch> for more accurate ahead/behind status detection and updated rebase conditions.
src/ai_company/communication/meeting/_parsing.py
- Adjusted the _ASSIGNEE_RE regex to specifically match 'assigned' instead of 'assigned?' to prevent incorrect assignee extraction from phrases like 'assign to X'.
src/ai_company/config/schema.py
- Added a _VALID_STRATEGIES frozenset to TaskAssignmentConfig to define acceptable assignment strategy names.
- Implemented a model_validator in TaskAssignmentConfig to ensure that the configured strategy name is one of the known valid strategies.
- Updated the description for max_concurrent_tasks_per_agent to clarify that enforcement is done by scoring-based strategies.
src/ai_company/engine/assignment/models.py
- Introduced max_concurrent_tasks as an optional integer field in AssignmentRequest to specify the maximum concurrent tasks an agent can handle, used for capacity filtering.
src/ai_company/engine/assignment/protocol.py
- Expanded the docstring for TaskAssignmentStrategy to detail the error signaling contract for different strategy types, clarifying when exceptions are raised versus when selected=None is returned.
- Added detailed Returns and Raises documentation to the assign method of TaskAssignmentStrategy to reflect the error signaling contract.
src/ai_company/engine/assignment/strategies.py
- Modified _score_and_filter_candidates to include filtering agents based on max_concurrent_tasks and their current workload, if provided.
- Added logic to build a workload_map and skip agents whose active_task_count meets or exceeds request.max_concurrent_tasks.
src/ai_company/engine/workspace/git_worktree.py
- Extended _validate_git_ref to accept error_cls and event parameters, allowing callers to specify context-appropriate exception types and log events.
- Updated calls to _validate_git_ref in merge_workspace and teardown_workspace to pass WorkspaceMergeError and WorkspaceCleanupError respectively.
- Added an asyncio.CancelledError exception handler to _run_git to ensure that the subprocess is killed and awaited before re-raising the cancellation error, preventing orphaned processes.
tests/unit/communication/meeting/test_parsing.py
- Added test_assign_to_not_matched_as_assignee to verify that 'assign to X' phrases are not incorrectly parsed as assignee assignments.
tests/unit/config/conftest.py
- Imported TaskAssignmentConfig into the conftest.
- Added task_assignment = TaskAssignmentConfig() to RootConfigFactory to ensure it's included in default root configurations.
tests/unit/config/test_schema.py
- Added test_valid_strategy_names_accepted to confirm that known assignment strategy names are successfully validated.
- Included test_unknown_strategy_rejected to assert that an unknown strategy name raises a ValidationError.
- Added test_empty_strategy_rejected to ensure that an empty strategy name also raises a ValidationError.
tests/unit/engine/test_assignment_strategies.py
- Added TestMaxConcurrentTasksEnforcement class with test_agent_at_capacity_excluded to verify agents at their max_concurrent_tasks limit are filtered out.
- Included test_no_limit_keeps_all_agents to confirm that without a max_concurrent_tasks limit, all agents remain eligible regardless of workload.
tests/unit/engine/test_cost_optimized_assignment.py
- Updated the assertion message in test_empty_workloads_falls_back_to_capability from 'no cost data' to 'insufficient cost data' to match implementation wording.
- Changed the expected winner in test_partial_cost_data from 'unknown-dev' to 'known-dev' due to revised fallback logic and sort stability with incomplete cost data.
tests/unit/engine/test_strategy_registry.py
- Modified the assertion for _scorer access to use getattr(strategy, '_scorer', None) to correctly handle protocol types, resolving a mypy attr-defined error.
tests/unit/engine/test_workspace_git_worktree.py
- Added TestValidateGitRefContextExceptions to verify that _validate_git_ref raises WorkspaceMergeError, WorkspaceCleanupError, or WorkspaceSetupError based on the calling context.
- Introduced TestRunGitCancelledError with test_cancelled_error_kills_process to confirm that _run_git properly kills and waits for subprocesses when an asyncio.CancelledError occurs.

In `@tests/unit/communication/meeting/test_parsing.py`:
- Around line 85-92: In test_assign_to_not_matched_as_assignee, add an assertion
that verifies result[0].description remains the original action text (e.g.,
"Please assign to bob the new module") so the test validates that
_parse_assignee did not strip or mutate the description; specifically assert the
value of result[0].description equals the expected description derived from the
input text.

In `@tests/unit/config/test_schema.py`:
- Around line 552-562: Replace the manual for-loop in
test_valid_strategy_names_accepted with pytest's parameterization: add
`@pytest.mark.parametrize` to feed each strategy string into the single test
function, keep the test body to instantiate TaskAssignmentConfig(strategy=name)
and assert cfg.strategy == name; this will replace the loop and make failures
show the specific failing strategy and test case name.

In `@tests/unit/engine/test_assignment_strategies.py`:
- Around line 471-557: Add a new test method
test_all_agents_at_capacity_returns_none to TestMaxConcurrentTasksEnforcement
that constructs AgentTaskScorer and RoleBasedAssignmentStrategy, creates two
agents via make_assignment_agent, a task via make_assignment_task, and an
AssignmentRequest with max_concurrent_tasks set and workloads where each
AgentWorkload has active_task_count >= max_concurrent_tasks; call
strategy.assign(request) and assert result.selected is None and the
result.reason mentions capacity/threshold. Use the same helper symbols
(AgentTaskScorer, RoleBasedAssignmentStrategy, make_assignment_agent,
make_assignment_task, AssignmentRequest, AgentWorkload, SeniorityLevel,
Complexity) so it fits the existing test structure.
