**Issue Evaluation**
Category: `enhancement` | Status: **Evaluated**
**Feasibility:** Feasible
**Scope:** Studio instance providers (Aliyun, Tencent), `MessageService`,
web capability gating
**Compatibility:** No breaking changes — additive capability contract
(`DIRECT_MESSAGE_CONSUME`), existing Apache provider behavior unchanged.
**Assessment:**
This is a well-structured proposal that addresses a real gap: the
message-detail dialog renders a direct-consume action for cloud providers that
do not implement it, resulting in HTTP 501 at runtime. The design correctly:
1. **Introduces a capability contract** (`DIRECT_MESSAGE_CONSUME`) so the UI
can fail closed before the user reaches the unsupported action — this is the
right pattern for multi-provider feature gating.
2. **Leverages existing cloud SDK methods** (`VerifyConsumeMessage` for
Aliyun, `VerifyMessageConsumption` for Tencent) already declared in the Studio
dependency tree, avoiding new external dependencies.
3. **Keeps provider-specific response mapping isolated** — Aliyun maps
`success+data` to `CR_SUCCESS`/`CR_FAILED`, Tencent maps SDK completion to
`CR_SUCCESS` with request-id remark. Both treat null responses as 502, which is
correct.
4. **Handles web-side gating** via `/instances/{id}/capabilities` with
proper stale-response invalidation on instance switch.
**Minor considerations for implementation:**
- The `spentTimeMillis` measurement should wrap the full provider call
(including SDK timeout) for consistency with the Apache path.
- Consider whether `DIRECT_MESSAGE_CONSUME` should be cached per-session or
always re-fetched on instance switch — the current design implies re-fetch,
which is safer.
- The capability endpoint should return a `maxAge` or `etag` to allow
client-side caching without stale data.
Overall, this is a clean, well-scoped enhancement with a solid design. Ready
for implementation.
