Filter Semantic

filter-semantic

Apply a natural-language predicate to each item in a list and return the items that match (or, with mode: "exclude", the items that don't).

Status: the tool exists in src/tools/ but is not yet exposed via the chat ReAct catalog. The list-shape input convention hasn't been settled (chat ReAct passes strings as $stepN bindings; the OODA executor passed Collection IDs). When wired, the args contract above will be revised to match the chosen shape.

Predicate guidance

• Semantic: "has a positive tone", "contains code or implementation details"
• Boolean: "mentions safety AND published after 2024"
• Numeric / date: "price under $50", "earlier than 2020"

Phrase predicates to describe what to match. Use mode: "exclude" instead of writing negative predicates ("does NOT contain X").

Why this is different from assess

• assess operates on one text, returns one bool.
• filter-semantic operates on many texts, returns the subset that match.

One tool call vs N tool calls for the same job.
