+

+ ## Subagent model tier configuration (including built-in Explore/Plan/General subagents and workflow fan-out subagents)

+

+ Concretizes the model-selection principle of RULES.md (if exists), which this

+ table implements — pass `model:` explicitly on every dispatch; never silently inherit

+ the session model.

+

+ - Reconnaissance, exploration, summarization, and retrieval: **Sonnet** by default;

+ escalate to **Opus** only when the digest's precision directly gates downstream

+ design quality (e.g. ADR/issue digests feeding a design gate).

+ - Large fan-out stages (N-vote adversarial panels, bulk refutation voters, bulk

+ search/fetch): **Sonnet** per voter/fetcher; the single synthesis, judge, or

+ high-stakes verifier stays **Opus**.

+ - Design reviews, single-point adversarial validation, consistency checks, and

+ routine tasks: **Opus**.

+ - **Fable** is used only for main-loop coordination, orchestration, final judgment,

+ or the design and implementation of the most complex tasks.
