Implementation Task Executor

Type: L3 Worker

Executes a single implementation (or refactor) task from Todo to To Review using the task description and linked guides.

Purpose & Scope

• Handle one selected task only; never touch other tasks.
• Follow task Technical Approach/plan/AC; apply KISS/YAGNI and guide patterns.
• Update tracker/kanban for this task: Todo -> In Progress -> To Review.
• Run typecheck/lint; update docs/tests/config per task instructions.
• Not for test tasks (label "tests" goes to ln-404-test-executor).

Hex MCP acceleration (if available): Use narrow inspect_path(path=<relevant dir>) and outline(file_path) before reading large code files; avoid repo-root wildcard inventories unless you intentionally need one. Use grep_search(output_mode="summary") first for search/discovery, then escalate to output_mode="content", edit_ready=true only when you need canonical hunks for follow-up edits; use allow_large_output=true only as an explicit last resort. Use read_file() in discovery mode for structure and targeted ranges; when you need revision and checksums for a follow-up edit, refresh that file with read_file(edit_ready=true, verbosity="full") before edit_file(). For edits to existing code, run index_project(path=project_root) once and use analyze_edit_region(...) before non-trivial edits. After edits: edit_file(base_revision=rev) -> verify(checksums). Before handoff: changes() to review diff.
