THE ONLY ENTRY POINT FOR CC10X. Activate this skill for build, debug, review, and plan requests. Use when the user asks to implement, fix, review, plan, test, refactor, or continue code work. Trigger keywords: build, implement, create, write, add, review, audit, debug, fix, error, bug, broken, plan, design, architect, spec, brainstorm, test, refactor, optimize, update, change, research, cc10x, c10x. CRITICAL: Route and execute immediately. Do not stop at describing capabilities.
Implementation skill for writing production code with TDD. Covers the RED-GREEN-REFACTOR cycle, false-RED detection, vertical slicing, scope escalation, test process discipline, and code generation patterns. Loaded by component-builder and bug-investigator.
Resolve an in-progress git merge or rebase conflict hunk by hunk — see the state, find the primary sources for each side's intent, resolve by intent (never --abort), run the project's checks, and finish the operation. Model- invoked: agents reach for it when a git operation reports conflicts.
Canonical deep-module vocabulary (module, interface, depth, seam, adapter, leverage, locality) for designing a module's shape — a lot of behaviour behind a small interface at a clean seam, testable through that interface. The single source of truth for these terms; other skills (architecture, codebase-hygiene, building, planning) point here instead of restating them. Use when designing or improving a module's interface, finding deepening opportunities, deciding where a seam goes, or making code more testable.
Two-mode skill: (1) find semantic duplicates — functions doing the same thing under different names, invisible to copy-paste detectors; (2) deepen shallow modules — thin wrappers and pass-through layers that spread complexity. Advisory and read-only; changes route through BUILD with full gates.
Use when a BUILD phase completes, a commit is staged, or a PR is about to be created, and the diff has not yet been reflected in documentation. Also use when the user says "update docs", "sync docs", "document this", or asks whether documentation is up to date.
Shared preamble loaded by all cc10x agents — memory protocol, contract format, output rules.
Greenfield architecture design: map functionality flows, draw components, design APIs, classify dependencies, plan observability. For multi-component, API, schema, auth, or integration-heavy work. For retrofitting existing code, use codebase-hygiene instead.
