Summary

Adds a provision_workspace MCP tool so an agent (the orchestrator) can provision a workspace with a guaranteed runtime (claude-code, codex, hermes, openclaw, langgraph, autogen, crewai, deepagents, BYO external/kimi) and fail-closed if the platform cannot honor it.

Before this, no agent-facing provisioning tool enforced runtime fidelity. create_workspace exists but returns a bare 201 even when the platform silently falls back to langgraph (the #184 / molecule-controlplane#188 footgun — 5/5 codex/claude-code requests came up langgraph).

What it does

  • (1) Validates runtime against the supported set before any side effect (defense-in-depth on top of the SDK enum) — clear UNSUPPORTED_RUNTIME instead of a silent langgraph coercion.
  • (2) Calls the correct product create path: POST /workspaces with both template (defaults to <runtime>-default) and runtime — NOT the CP-direct /cp/workspaces/provision path the orchestrator had been forced to use.
  • (3) Reads the created workspace back and asserts resolved runtime == requested. On mismatch returns a structured RUNTIME_MISMATCH / PROVISION_UNVERIFIED error with the resolved value, provisioned:false — the caller can no longer mistake a langgraph fallback for success.

This makes the agent-facing surface honest now. It does not replace the required platform-side hard-gate — see molecule-controlplane#188 and its workspace-server sibling (the product Create path at workspace.go:245-247 defaults empty/unknown runtime to langgraph with no validation, same root-cause family). Per the CTO framing: each adapter stays runtime-specific; the platform is the unified SSOT that must hard-gate / error+notify, never silent-advisory.

Refs: molecule-controlplane#188, #184.

Test plan

  • npx tsc --noEmit clean
  • npm test — 133 passed (3 suites), incl. 5 new handleProvisionWorkspace tests: unsupported-runtime (no side effect), RUNTIME_MISMATCH on langgraph fallback, ok=true only on match, PROVISION_UNVERIFIED on unreadable runtime, BYO external not falsely failed
  • npm run build clean; provision_workspace present in dist/
  • tool-count assertion updated 87 → 88
  • Non-author review (do not self-merge / no admin-merge / no CI bypass)

## Summary Adds a `provision_workspace` MCP tool so an agent (the orchestrator) can provision a workspace with a **guaranteed runtime** (`claude-code`, `codex`, `hermes`, `openclaw`, `langgraph`, `autogen`, `crewai`, `deepagents`, BYO `external`/`kimi`) and **fail-closed** if the platform cannot honor it. Before this, no agent-facing provisioning tool enforced runtime fidelity. `create_workspace` exists but returns a bare 201 even when the platform silently falls back to `langgraph` (the #184 / molecule-controlplane#188 footgun — 5/5 codex/claude-code requests came up langgraph). ## What it does - (1) Validates `runtime` against the supported set **before any side effect** (defense-in-depth on top of the SDK enum) — clear `UNSUPPORTED_RUNTIME` instead of a silent langgraph coercion. - (2) Calls the **correct product create path**: `POST /workspaces` with both `template` (defaults to `<runtime>-default`) and `runtime` — NOT the CP-direct `/cp/workspaces/provision` path the orchestrator had been forced to use. - (3) Reads the created workspace back and asserts `resolved runtime == requested`. On mismatch returns a structured `RUNTIME_MISMATCH` / `PROVISION_UNVERIFIED` error with the resolved value, `provisioned:false` — the caller can no longer mistake a langgraph fallback for success. This makes the **agent-facing surface honest now**. It does **not** replace the required platform-side hard-gate — see molecule-controlplane#188 and its workspace-server sibling (the product `Create` path at `workspace.go:245-247` defaults empty/unknown runtime to `langgraph` with no validation, same root-cause family).

feat(workspaces): add fail-closed provision_workspace MCP tool
CI / test (pull_request) Successful in 57s
Details
549c15c594 
Adds a `provision_workspace` MCP tool so an agent can provision a
workspace with a GUARANTEED runtime (claude-code/codex/hermes/openclaw/
langgraph/autogen/crewai/deepagents) via the correct PRODUCT create path
(POST /workspaces with template+runtime) — not the CP-direct
/cp/workspaces/provision path the orchestrator was forced to use.

Enforces the same fail-closed contract as molecule-controlplane#188 on
the agent-facing surface:
  1. Validate runtime against the supported set BEFORE any side effect.
  2. Create via the product path (template drives config/image).
  3. Read the workspace back and assert resolved runtime == requested;
     return a structured RUNTIME_MISMATCH/PROVISION_UNVERIFIED error
     (NOT a success) if the platform silently fell back to langgraph.

This makes the agent surface honest now; it does NOT replace the
required platform-side hard-gate (controlplane#188 + its workspace-
server sibling — each adapter stays runtime-specific, the platform is
the unified SSOT that must error+notify, never silent-advisory).

Refs: molecule-controlplane#188, #184 (CP-direct vs product-create
fidelity gap).

feat(workspaces): fold apply-role-config + read-back-assert into provision_workspace
CI / test (pull_request) Successful in 1m7s
Details
8e64f9f107 
Extends the fail-closed provision_workspace tool with an optional
role_config { model, config_yaml } block so "create + apply-role-config
+ read-back-assert" is ONE fail-closed operation instead of two
separate, skippable steps.

Motivation (#218 prod-team defect): the 5 prod-team workspaces were
provisioned with the correct runtime but template-default role config
(generic name, Sonnet instead of the role's model, empty charter)
because per-role config was never applied as part of provisioning.

Mechanism (source-verified against molecule-core workspace-server):
- model      -> PUT /workspaces/:id/model (writes MODEL_PROVIDER
  workspace_secret; authoritative over config.yaml runtime_config.model
  per the claude-code adapter resolution order; auto-restarts). The
  effective model is read back via GET /workspaces/:id/model and
  ASSERTED == requested; a write-ack is never trusted as success.
- config.yaml -> PUT /workspaces/:id/files/config.yaml (name,
  description/charter, runtime_config.model, required_env; written via
  EIC to the workspace EC2 + auto-restarts). NOT read-back-asserted
  due to the documented PUT/GET path asymmetry (molecule-core
  tests/e2e/test_staging_full_saas.sh) — the model read-back is the
  authoritative effective-config gate.

Fail-closed surface: ROLE_CONFIG_FAILED (write error, with phase),
ROLE_CONFIG_MODEL_MISMATCH (effective model != requested after
read-back). role_config_applied is always present in the result so a
caller cannot mistake a runtime-only provision for a fully-configured
role.

Tests: +3 (success path, model-mismatch fail-closed, role_config
absent). Full suite green: 136 passed, 1 skipped.

Extended this PR with role_config { model, config_yaml } on provision_workspace so create + apply-role-config + read-back-assert is ONE fail-closed op (folds in the #218 prod-team role-config fix). Model is read-back-asserted via GET /workspaces/:id/model (authoritative over config.yaml per the claude-code adapter resolution order); config.yaml is written via the Files API but NOT read-back-asserted due to the documented PUT/GET path asymmetry (molecule-core tests/e2e/test_staging_full_saas.sh:564-572). +3 tests, full suite green (136 passed). Normal review please — NO merge / no CI bypass. Live application to the 5 prod-team workspaces was done out-of-band via the same canonical endpoints and read-back-verified (all 5 PASS, all online).

Non-author Five-Axis review — REQUEST-CHANGES (small ask — last 10% of the contract this PR claims).

The fail-closed core is correct and well-tested: ROLE_CONFIG_MODEL_MISMATCH aborts provision (not just log); read-back via GET /workspaces/:id/model is the authoritative effective-config gate (not the PUT write-ack); 8 new test cases cover the right control-flow branches; the BYO carve-out is sensible. CI green.

Two items hold this back from APPROVE-recommend, both ≤30 LoC:

  1. Add SUPPORTED_TEMPLATES allow-list — defense-in-depth on the template footgun (the WHOLE POINT of this PR). Today: runtime is enum-gated (✓), but params.template is passed through unmodified. Per the verified-2026-05-17 footgun memo: invalid template silently → langgraph (201, no error); valid ids are {autogen, claude-code-default, codex, hermes, langgraph, openclaw}; claude-code MUST be remapped to claude-code-default. The runtime read-back catches the silent-langgraph case as a backstop, so effective behavior is fail-closed, but defense-in-depth missing. Add a parallel SUPPORTED_TEMPLATES set and reject pre-POST. Also: defaultTemplateFor returns ${runtime}-default for any runtime including ones whose template may not exist (e.g. crewai-default, deepagents-default) — assert constructed template is in the known set or document the assumption.

  2. Confirm apiCall/platformGet set a non-default User-Agent (e.g. molecule-mcp-server/x.y.z). If they send Python-urllib or default Node UA, Cloudflare returns 403 error-1010 at the edge and the whole tool fails with no actionable error in prod. Quick check of src/api.ts; if already set, drop this and re-review. (The async-A2A concern does NOT apply — read-back hits api.moleculesai.app CP host, not tenant-slug; no CF 524 surface.)

Non-blocking 5-axis findings:

  • Add PROVISION_FAILED + ROLE_CONFIG_FAILED test coverage (currently uncovered error branches).
  • BYO carve-out at line 379-380 should have an intentional-behavior comment.
  • defaultTemplateFor could return undefined directly instead of "" then || undefined (cosmetic).

Operational note: existing reviews from sdk-lead/sdk-dev are state=PENDING despite "Approved" prose — internal#503 wrong-enum mis-file. Re-submit with event:"APPROVED" exact-string after fixes.

PR#20 (CLAUDE.md sync) holds for this PR — sequencing review will follow once these two fixes land.

5-axis review on 8e64f9f:

Correctness: APPROVED. The PR adds and exports provision_workspace, registers it in workspace tools, updates the stable tool count to 88, and uses the product /workspaces create path followed by read-back runtime verification. Unsupported runtime, runtime mismatch, unreadable runtime, matching runtime, BYO external, and role_config model read-back paths are covered by tests.

Robustness: The handler fails before side effects on unsupported runtimes, returns structured non-success results for platform errors, missing workspace id, unreadable runtime, runtime mismatch, and role_config failures. CI is green on this head.

Security: No new secret exposure. Inputs are constrained through the MCP schema and runtime allowlist; the new calls stay within existing platform API helpers.

Performance: Adds one read-back GET after create, plus optional role_config writes/read-back. That is appropriate for a fail-closed provisioning contract and not a hot path.

Readability: The implementation is explicit about why this differs from create_workspace, and the tests document the expected failure modes clearly.
