Names the domain (complex coding tasks) and describes the methodology (state-machine driven iterative planning with Explore → Plan → Execute → Reflect → Pivot cycle), but the actual concrete actions are abstract process steps rather than specific coding actions like 'refactor modules' or 'migrate database schemas'.

Clearly answers both 'what' (state-machine driven iterative planning and execution with a defined cycle and filesystem as persistent memory) and 'when' (explicitly states 'Use for multi-file tasks, migrations, refactoring, failed tasks, or anything non-trivial').

Includes some useful trigger terms like 'multi-file tasks', 'migrations', 'refactoring', and 'failed tasks', but misses many natural variations users might say such as 'large refactor', 'complex project', 'step by step', 'break down this task', or 'code migration'. The term 'non-trivial' is vague and not something users typically say.

The methodology-focused description (state machine, iterative planning) is somewhat distinctive, but terms like 'refactoring', 'migrations', and 'complex coding tasks' could easily overlap with other coding-related skills. The catch-all 'anything non-trivial' significantly increases conflict risk.

This skill is extremely verbose at ~500+ lines. While the domain is complex, there is massive redundancy: the same rules (Mandatory Re-reads, Revert-First, 3-Strike, etc.) are restated multiple times across sections. Many sections explain concepts Claude already understands (what a state machine is, what git checkout does). The file lifecycle matrix, sub-agent architecture, and consolidated file management sections could be dramatically compressed.

The skill provides highly concrete, executable guidance: specific bash commands for bootstrapping, exact file paths and naming conventions, precise state transition triggers, detailed checklists with checkboxes, specific line count thresholds (>300 lines, >200 lines), and exact commit message formats. Every rule has a concrete action attached.

The state machine is exceptionally well-defined with explicit transitions, triggers, and validation checkpoints at every stage. The Post-Step Gate, Phase 1/2/3 REFLECT structure, Autonomy Leash with 2-attempt cap, and Gate-In mandatory reads provide thorough feedback loops. Destructive operations have explicit revert-first protocols and checkpoint requirements.

The skill references many external files (references/file-formats.md, references/complexity-control.md, agents/orchestrator.md, etc.) which is good progressive disclosure architecture. However, the SKILL.md itself is a monolithic wall of text that inlines enormous amounts of detail that could live in those reference files. The sub-agent architecture section, consolidated file management, and detailed REFLECT phases could be split out, keeping only summaries in the main file.
