feat(core): M3c-rest — TodoWrite + WebFetch + WebSearch tools#17
Merged
Conversation
Three Claude-Code-parity tools shipped, all registered in BUILTIN_TOOLS.
· TodoWrite — agent-managed task list, persisted to <sessionDir>/todos.json.
Validates `at most one in_progress`. readTodos() helper for UI.
· WebFetch — GET-only, 5 MiB cap (configurable via
DEEPCODE_WEBFETCH_MAX_BYTES), AbortSignal honored, streaming byte-cap so a
server that omits content-length can't blow memory.
· WebSearch — DuckDuckGo HTML by default; pluggable via
DEEPCODE_WEBSEARCH_URL_TEMPLATE for self-hosted SearXNG. Tolerant parser
with unit tests against stubbed HTML.
Tests: +21 in core (293/8 pass/skip), 41 in cli unchanged.
BEHAVIOR_PARITY.md updated — these three move from 🔄 to ✅.
