## Spec Compliance Matrix

| Requirement | Scenario | Test Evidence | Result |
|-------------|----------|---------------|--------|
| Effective Runtime Tool Inventory Listing | `/tools` lists the effective active runtime tools | `bootstrap::tests::slash_tool_snapshot_matches_effective_runtime_inventory`; `tests::cli_tools_command_returns_effective_tool_listing`; `session_commands::service::tests::tools_are_sorted_and_exposed_as_machine_readable_listing` | ✅ COMPLIANT |
| Effective Runtime Tool Inventory Listing | `/tools` includes MCP-derived tools only when they are effectively active | `bootstrap::tests::slash_tool_snapshot_keeps_effective_mcp_entries_when_active`; `bootstrap::tests::slash_tool_snapshot_matches_effective_runtime_inventory`; `session_commands::service::tests::tools_formats_mixed_native_and_mcp_sources` | ✅ COMPLIANT |
| Transport Parity for `/tools` Through the Shared Slash Ingress Seam | Recognized `/tools` uses the shared ingress seam across supported transports | `pre_execution::tests::ingress_routes_tools_through_shared_seam_with_tool_snapshot`; `tests::cli_tools_command_returns_effective_tool_listing`; `gateway::tests::maybe_handle_http_ingress_handles_tools_listing_through_shared_ingress`; `gateway::webhook_dispatch::tests::execute_intercepts_tools_listing_before_provider_execution`; `channels::tests::ingress_outcome_handles_tools_listing_through_shared_ingress` | ✅ COMPLIANT |
| Transport Parity for `/tools` Through the Shared Slash Ingress Seam | Transport wrappers do not change the `/tools` inventory meaning | Shared runtime path is exercised across CLI/gateway/webhook/channel tests and machine-readable payload is validated in `session_commands::service::tests::tools_are_sorted_and_exposed_as_machine_readable_listing`, but there is no single cross-surface assertion comparing equivalent inventories end-to-end | ⚠️ PARTIAL |
| Read-Only Scope Boundary for Initial Tool Slash Commands | Mutation-oriented slash families remain out of scope in this slice | `session_commands::registry::tests::default_registry_exposes_built_in_descriptors` proves only `/tools`, `/resume`, `/suspend`, `/tldr`, `/compact` are registered; no direct runtime test enumerates the exact out-of-scope commands from the spec | ⚠️ PARTIAL |
| Read-Only Scope Boundary for Initial Tool Slash Commands | Out-of-scope mutation commands do not gain new handled semantics from this change | Static evidence in registry/type/service files shows no handlers or success contracts for `/tool enable`, `/tool disable`, `/mcp add`, `/mcp remove`, `/model`, `/provider`, `/temperature`; existing `tests::cli_unknown_slash_like_input_falls_through` supports the general fall-through behavior, but exact command strings are not directly exercised | ⚠️ PARTIAL |

**Compliance summary**: 3/6 fully compliant, 3/6 partial, 0 failing, 0 untested.

## Correctness (Static — Structural Evidence)

| Requirement | Status | Notes |
|------------|--------|-------|
| Effective Runtime Tool Inventory Listing | ✅ Implemented | `SessionCommandToolEntry`, `SessionCommandSuccessData::ToolListing`, `handle_tools()`, and bootstrap snapshot helpers implement the read-only effective inventory contract. |
| Transport Parity for `/tools` Through the Shared Slash Ingress Seam | ✅ Implemented | `pre_execution::evaluate_ingress(...)` now accepts the tool snapshot, and CLI/gateway/webhook/channel call sites thread the same shared input. |
| Read-Only Scope Boundary for Initial Tool Slash Commands | ✅ Implemented | Registry registers `/tools` only; no mutation command family handlers, persistence flows, or new mutation contracts were added. |

---

## Coherence (Design)

| Decision | Followed? | Notes |
|----------|-----------|-------|
| Pass a read-only tool snapshot through the slash service boundary | ✅ Yes | `evaluate_ingress(...)` and `SessionCommandService::with_tool_snapshot(...)` use a compact snapshot instead of mutable config/runtime handles. |
| Keep the slash-facing snapshot smaller than the full capability descriptor model | ✅ Yes | The implementation uses `SessionCommandToolEntry` and `SessionCommandToolSourceKind`, not raw capability registry descriptors in slash handlers. |
| Preserve transport adaptation by adding structured success data | ✅ Yes | `SessionCommandSuccessData::ToolListing { tools }` was added while existing outward wrappers continue using `success.message`. |
| File changes match design file list | ✅ Yes | All design-listed runtime files were updated and no out-of-scope mutation surface was introduced. |

## Issues Found

**CRITICAL** (must fix before archive): None

**WARNING** (should fix):

1. The spec’s out-of-scope mutation commands are not exercised with exact runtime inputs (`/tool enable`, `/mcp add`, `/model`, etc.); current evidence is structural plus a generic unknown-slash fall-through test.
2. Cross-transport parity is strongly implied by the shared ingress seam and wrapper tests, but there is no single behavioral assertion comparing equivalent `/tools` inventory semantics across two outward transports.

**SUGGESTION** (nice to have):

1. Add a compact regression test matrix for the exact out-of-scope mutation commands to lock the slice boundary explicitly.
2. Add one parity test that compares shared `/tools` payload semantics across two ingress surfaces using the same snapshot fixture.

---

## Verdict

**PASS WITH WARNINGS**

The implementation satisfies the design and core behavioral requirements for a read-only registry-backed `/tools` command, and all relevant validation commands passed. Remaining gaps are limited to missing explicit runtime assertions for exact out-of-scope mutation inputs and stronger cross-transport semantic parity checks.
