Three independent fixes to src/core/minions/handlers/subagent.ts. Each is covered by its own test set; bundled in one commit because they touch overlapping lines of subagent.ts (cleaner than 3 hunk-split commits). Bug 1 — rate-lease default 8 → 32 + `unlimited` sentinel src/core/minions/handlers/subagent.ts:61 Pre-v0.41 the default cap of 8 starved 10-concurrency batches on upstreams with no provider-side rate limit (Azure/Bedrock/self-hosted). New resolveLeaseCap() bumps default to 32, accepts `unlimited`/`none` as POSITIVE_INFINITY sentinel, throws on NaN/negative/zero with a paste-ready hint. Codex pass-1 #7 caught the original `=0`/`NaN`-uncapped semantics as dangerous (universal convention is "0 means disabled"). Pinned by test/rate-leases-uncapped.test.ts (15 cases). Bug 3 — strip `provider:` prefix at Anthropic SDK call site src/core/minions/handlers/subagent.ts:439, ~:895 `gbrain agent run --model anthropic:claude-sonnet-4-6` pre-fix sent the qualified string straight to client.messages.create which Anthropic rejects with "model not found." New stripProviderPrefix() applies at the one SDK call site; `model` stays qualified everywhere else (persistence, recipe lookup, capability gate). Pinned by 4 new test/subagent-handler.test.ts cases. Approach C — composable system prompt renderer w/ per-tool usage_hint src/core/minions/system-prompt.ts (NEW) src/core/minions/types.ts (ToolDef.usage_hint + SubagentHandlerData.system_no_tool_preamble) src/core/minions/tools/brain-allowlist.ts (BRAIN_TOOL_USAGE_HINTS) src/core/minions/handlers/subagent.ts (wiring) Bug 4 absorbed: pre-v0.41 DEFAULT_SYSTEM was one generic line that gave the model no guidance on WHICH tool to reach for. The field-report case was a `shell` tool sitting unused because nothing told the model to reach for it. New deterministic renderer splices a tool-usage preamble listing each tool's name + usage_hint; closing paragraph names shell/bash explicitly + tells the model brain tools write to the DB (not local files). Determinism preserved for Anthropic prompt-cache marker stability. Pinned by 13 cases in test/system-prompt.test.ts (determinism, opt-out, plugin tools, cache safety).
