From 9147578155c67bad94f9be4f480d552b33e354d5 Mon Sep 17 00:00:00 2001 From: Ed_ Date: Sat, 6 Jun 2026 18:15:15 -0400 Subject: [PATCH] conductor(plan): write 2-phase implementation plan for data_structure_strengthening_20260606 ~22 tasks across 2 phases, each with explicit Red-Green-Refactor TDD steps: - Phase 1 (1.1-1.12): Foundation. type_aliases.py (10 TypeAliases + 1 NamedTuple) with 8 unit tests. Mechanical replacement of 345 weak sites in 6 files (ai_client 139, app_controller 86, models 51, api_hook_client 32, project_manager 20, aggregate 17). Each file has a per-substitution table for the mechanical replacement. Audit script gains --strict mode + baseline file (CI gate). 4 audit tests. - Phase 2 (2.1-2.10): FileItemsDiff NamedTuple integrated. generate_type_registry.py (AST-based; 3 modes: default, --check, --diff). Initial registry generated in docs/type_registry/ (8+ .md files). 6 generator tests. Type aliases styleguide + product-guidelines updates. Manual smoke test. Track archived. The type registry generator uses --check mode for CI: it regenerates to a temp dir and diffs against the committed registry; exit 1 if drift. The agent's track-completion workflow is: regenerate -> review diff -> commit. CI enforces --check on every PR. Self-review at the end maps every spec section to a task (no gaps), confirms zero placeholders, and verifies type/method-name consistency across phases (all 10 aliases + FileItemsDiff defined in Task 1.2; used consistently in Tasks 1.3-1.8 and Phase 2). --- .../plan.md | 1366 +++++++++++++++++ 1 file changed, 1366 insertions(+) create mode 100644 conductor/tracks/data_structure_strengthening_20260606/plan.md diff --git a/conductor/tracks/data_structure_strengthening_20260606/plan.md b/conductor/tracks/data_structure_strengthening_20260606/plan.md new file mode 100644 index 00000000..e703ea8b --- /dev/null +++ b/conductor/tracks/data_structure_strengthening_20260606/plan.md @@ -0,0 +1,1366 @@ +# Data Structure Strengthening (Type Aliases + NamedTuples) — Implementation Plan + +> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Introduce 10 `TypeAlias` definitions and 1 `NamedTuple` to name the 430 anonymous `dict[str, Any]` / `list[dict[...]]` / `Tuple[...]` types in the codebase; mechanically replace 345 weak sites across 6 high-traffic files. Add an auto-generated `docs/type_registry/` directory that gives the LLM field-level schema information on demand. Make `scripts/audit_weak_types.py` a permanent CI gate with `--strict` mode. + +**Architecture:** Data-oriented. The aliases are TYPE-LEVEL ONLY (runtime behavior unchanged). Each alias is a name for a `dict[str, Any]` (or list of) used in a specific semantic role: `Metadata` (root), `CommsLogEntry` / `CommsLog` (comms ring buffer), `HistoryMessage` / `History` (AI provider history), `FileItem` / `FileItems` (context file list), `ToolDefinition` / `ToolCall` (model tools), `CommsLogCallback` (callback signature). The type registry is a separate `scripts/generate_type_registry.py` AST tool that reads `src/` and writes per-source-file `.md` docs with field-level info; the LLM reads these on demand (token cost: 200-500 lines of markdown per query, bounded). + +**Tech Stack:** Python 3.11+, stdlib `ast`, `dataclasses`, `typing.TypeAlias`, `typing.NamedTuple`, `pathlib`, `re`. No new dependencies. **1-space indentation mandatory.** No comments in production code (per project style). + +**Reference:** See `conductor/tracks/data_structure_strengthening_20260606/spec.md` for the full design, per-file refactor details, and AI performance analysis. + +--- + +## File Structure + +| File | Action | Responsibility | +|---|---|---| +| `src/type_aliases.py` | Create | 10 `TypeAlias` definitions + 1 `NamedTuple` | +| `src/ai_client.py` | Modify | Import aliases; replace 139 weak sites (largest offender) | +| `src/app_controller.py` | Modify | Import aliases; replace 86 weak sites | +| `src/models.py` | Modify | Import aliases; replace 51 weak sites | +| `src/api_hook_client.py` | Modify | Import aliases; replace 32 weak sites | +| `src/project_manager.py` | Modify | Import aliases; replace 20 weak sites | +| `src/aggregate.py` | Modify | Import aliases; replace 17 weak sites | +| `scripts/audit_weak_types.py` | Modify | Add `--strict` mode (CI gate) | +| `scripts/audit_weak_types.baseline.json` | Create | Post-Phase-1 baseline count (~60) | +| `scripts/generate_type_registry.py` | Create | AST-based registry generator (3 modes) | +| `docs/type_registry/index.md` | Create (generated) | Top-level TOC + summary | +| `docs/type_registry/type_aliases.md` | Create (generated) | The 10 TypeAliases + 1 NamedTuple | +| `docs/type_registry/ai_client.md` | Create (generated) | Per-source-file: ai_client structs | +| `docs/type_registry/app_controller.md` | Create (generated) | Per-source-file: app_controller structs | +| `docs/type_registry/models.md` | Create (generated) | Per-source-file: models structs | +| `docs/type_registry/api_hook_client.md` | Create (generated) | Per-source-file: api_hook_client structs | +| `docs/type_registry/project_manager.md` | Create (generated) | Per-source-file: project_manager structs | +| `docs/type_registry/aggregate.md` | Create (generated) | Per-source-file: aggregate structs | +| `docs/type_registry/result_types.md` | Create (generated) | From data_oriented_error_handling_20260606 (Result/ErrorInfo) | +| `conductor/code_styleguides/type_aliases.md` | Create | Canonical reference for the alias convention | +| `conductor/product-guidelines.md` | Modify | New "Data Structure Conventions" section | +| `tests/test_type_aliases.py` | Create | Verify aliases import + resolve to right types | +| `tests/test_audit_weak_types.py` | Create | Verify regex patterns, Finding dataclass, report format | +| `tests/test_generate_type_registry.py` | Create | Verify AST extraction + output format | + +--- + +# Phase 1: Aliases + 6-file replacement + audit baseline + +> Goal: `src/type_aliases.py` exists. 345 weak sites replaced across 6 files.

Type consistency:** `Metadata`, `CommsLogEntry`, `CommsLog`, `HistoryMessage`, `History`, `FileItem`, `FileItems`, `ToolDefinition`, `ToolCall`, `CommsLogCallback`, `FileItemsDiff` defined in Task 1.2; used consistently in Tasks 1.3-1.8 (substitution tables) and Tasks 2.1, 2.4, 2.6, 2.7. `Result[T]` from `data_oriented_error_handling_20260606` is referenced in Task 1.1's test `test_result_with_file_items_alias_composes`; the script in Task 2.4 also references it. + +No issues found.
