Second-pass cleanup after the monolith split. Addresses every issue
from the code-review pass.
Core additions in src/api.ts:
- toMcpResult(data) + toMcpText(text): single source of truth for the
MCP text-content envelope (was ~87 duplicated literals)
- ApiError type + isApiError(v) guard: typed discriminated-union for
the error-by-value pattern; replaces open-coded shape checks
- apiCall<T = unknown>: generic so callers can document expected
response shape without unchecked "as" casts
Bulk cleanups across all 12 tools/*.ts:
- Every handler now returns toMcpResult(data) or toMcpText(text)
- Open-coded "typeof obj === 'object' && 'error' in obj" in
remote_agents.ts replaced with isApiError(v)
- Extracted initialCanvasPosition() helper out of
handleCreateWorkspace; explains why random seeding exists
- Added runtime/workspace_dir/workspace_access to create_workspace
zod schema (previously accepted by handler but hidden from clients)
src/index.ts:
- Replaced "export * from" with explicit named re-exports so the
public surface is auditable and future name collisions fail loudly
Tests:
- createServer() smoke test that records every srv.tool(...) call and
asserts 87 registered tools unique by name. Catches future PRs that
forget to wire a registerXxxTools(srv).
Docs:
- Fix broken relative links in sdk/python/molecule_agent/README.md
(was ../../examples/ from inside sdk/python/, should be ../examples/)
- Update stale "61 tools" -> "87 tools" in CLAUDE.md + main() log
Verification:
- npm run build clean
- npx jest -> 97/97 passed (was 96; +1 smoke test)
- grep "content: [{ type: \"text\" as const" src/tools/ -> 0 matches
- No file over 216 lines

The get_remote_agent_setup_command handler emitted
\`python3 -m examples.remote-agent.run\` — an invalid Python module path
(dashes not allowed in module names), so the command never actually
worked. Replace with a direct \`python3 -c "..."\` snippet that imports
from \`molecule_agent\` (the real SDK module) and points to the demo
script for reference.
Fixes the pre-existing jest failure in \`handleGetRemoteAgentSetupCommand
emits bash for external workspace\` that was flagged against PR #2.
Updates test expectation to \`molecule_agent\` (the actual importable
module name) from the never-valid \`molecule-agent\`.

Pure mechanical split, no behavior changes. Pulls the 70+ tool handlers
out of one monolith into api.ts (PLATFORM_URL + apiCall) plus 12
tools/*.ts files grouped by domain (workspaces, agents, secrets, files,
memory, plugins, channels, delegation, schedules, approvals, discovery,
remote_agents). Each module exports its handlers and a
registerXxxTools(srv) function; createServer() wires them up.
index.ts drops from 1697 → 89 lines. Largest new file is 183 lines.
All handlers still re-exported from index.ts so existing tests that
import them via "../index.js" keep working. Build clean; jest results
unchanged from pre-refactor baseline.
