Maintainer feedback (#4071 review): the original guard rejected
sisyphus and atlas as subagent targets even from team-mode where
resolveMember() intentionally calls resolveSubagentExecution with
allowPrimaryAgentDelegation: true. Per AGENT_ELIGIBILITY_REGISTRY
(src/features/team-mode/types.ts), only prometheus is hard-reject;
sisyphus and atlas are explicitly verdict: 'eligible' for team
membership.
Shrink COORDINATOR_AGENT_NAMES to ['prometheus'] so the guard
aligns with the registry's authoritative classification, document
the scoping rule in a comment, and add regression tests covering:
- sisyphus is NOT blocked by the coordinator guard (registry eligible)
- atlas is NOT blocked by the coordinator guard (registry eligible)
- prometheus IS blocked even when allowPrimaryAgentDelegation: true
(registry hard-reject is authoritative)
Fixes the 5 zauc-mocks resolver tests that were locking in the
wrong rejection set (including 'allows delegating to a primary
agent when allowPrimaryAgentDelegation is enabled'). The one test
asserting the literal primary-agent error string for Prometheus
display-name was loosened to a regex that accepts either guard's
message, since prometheus is now caught by the coordinator path
which fires before the primary-agent lookup.
Agents could select coordinator/meta agents (Prometheus, Atlas,
Sisyphus/Ultraworker) as subagent targets via task() / delegation,
producing duplicate orchestration loops and conflicting team state.
This is the inverse of #3987 / #4065 — symmetric guard on the
delegation TARGET side, using the same AGENT_ELIGIBILITY_REGISTRY
classification.
Add a runtime guard at the delegation entry point that rejects
task() calls whose subagent_type resolves to an agent marked as
hard-reject / coordinator-only in the eligibility registry, with
an actionable error naming the agent. Regression test asserts a
prometheus-targeted delegation is rejected before any subagent
session spawns.

- P1: When allowedEnvVars is provided, PATH was missing from the base
restricted env, causing non-builtin commands to fail at exec time
- P2: Allowlisted HOME/CLAUDE_PROJECT_DIR could overwrite normalized
values from getHomeDirectory()/cwd with ambient process.env values
- P2: Test suite mutated shared pluginHooksState singleton without
resetting it in afterEach, causing cross-test state leaks
Resolve built-in local MCP runtime executables before handing command arrays to OpenCode so lsp and ast_grep do not depend on a bare node or bun lookup in the host PATH.
Keep source, dist, bootstrap, workspace-safety, and disabled_mcps behavior covered by focused tests and real OpenCode MCP status QA.
Plan: plans/fix-built-in-mcp-runtime-executables.md
- Apply mcp_env_allowlist to plugin hooks: intersect HTTP allowedEnvVars
with MCP allowlist, set command allowedEnvVars to full MCP allowlist
- Scrub process.env in executeHookCommand when allowedEnvVars provided
- Add PluginHooksState class with per-directory Map storage
- Add PluginHooksConfig interface for typed boundary layer
- Pass directory context through hook-config-handler
- Add 16 tests across 4 files (40 assertions) covering allowlist
filtering, env scrubbing, directory isolation, and edge cases
- Remove unnecessary 'as' type assertions, use discriminated union
narrowing instead
