v2.0.0

Changed (breaking)

• Renamed /tdd to /implement. The slash command is now /implement <feature>. Speckit command ID is speckit.dev-workflow.implement (alias speckit.implement); the previous speckit.dev-workflow.tdd ID no longer resolves. Skill directory moved from skills/tdd/ to skills/implement/.
• Tracker filename convention is now impl-tracker-<feature>.json. The previous tdd-tracker-*.json prefix is no longer recognized by review-plan / review-impl.
• Phase 6 parallel reviewer is now /code-review (read-only) instead of /simplify (which writes to the tree). Running a writer concurrently with review-impl was racy; the review pair is now both read-only.
• This repo is now the only distribution channel. openkash/ai-agent-spec-skill and openkash/ai-agent-tdd-skill are deprecated; the spec-sync workflow and sync.sh script have been removed. Install via the Claude Code plugin or copy directly from this repo.

Added

• UI state-holder vs rendering-only distinction in the test-strategy table. UI chunks that introduce mutableStateOf, LaunchedEffect/useEffect, hoisted state, or input transformation must extract a state holder and unit-test its transitions. Pure prop/callback threading with no logic keeps the "no test" exemption.
• Both review-plan and review-impl now check the state-holder exemption explicitly. A chunk that claims "Pure UI — no test" while introducing a holder is flagged as a FAIL.
• Small-feature shortcut keeps both review gates. Only Plan Mode (Phase 2.4) and chunk decomposition (Phase 2.1-2.2) collapse for 1-chunk features; review-plan and review-impl + /code-review still run.

Migration

• Replace any saved /tdd <feature> invocations with /implement <feature>.
• Rename existing in-flight tracker files from tdd-tracker-*.json to impl-tracker-*.json if you want them picked up by the agents on resumption.
• Update any project-level docs or onboarding notes that reference skills/tdd/ to skills/implement/.
• If you customised skills/tdd/PROJECT.md, copy it to skills/implement/PROJECT.md before pulling — the directory rename means the old path will not exist after the update.
• The resume field on tracker chunks has been removed; per-chunk pattern hints and pitfalls now live in the optional notes field.
