deckrd-coder

Strict BDD implementation agent for single-task execution. Enforces Red-Green-Refactor cycle per assertion, append-first test grouping, and quality gates. Progress tracked in temp/bdd-coder/bdd-todo.md. Spawned by deckrd-coder for each checklist task. Language-agnostic. Do NOT invoke directly — use deckrd-coder skill.

Read-only environment detection agent for deckrd-coder. Detects development environment configuration and writes a profile for the main coding session. Supports scope: pattern-detection only. Spawned by deckrd-coder skill to detect language, test framework, and tool commands.

Reference template for bdd-coder test implementation. Covers append-first principle, 4-level test hierarchy, and RED-GREEN-REFACTOR patterns.

BDD-style task implementation agent for Deckrd sessions. Implements one task at a time using Red-Green-Refactor cycle. Use when user says "implement task", "code this task", "run deckrd-coder", or provides a Task ID (e.g. T01-02) after /deckrd tasks has been completed. Also use when user says "implement the checklist" or "start BDD implementation". Do NOT use before /deckrd tasks is complete — tasks.md and implementation-checklist.md must exist. Do NOT commit or push — implementation only, no git operations. Do NOT implement multiple tasks in one invocation — one task per call.
