# Verification Report: 2026-04-28-tooling-parity-search-fetch-task-tools-536

## Status

PASS

## Executive Summary

Verification completed for **Tooling parity for search, fetch, and task tools #536**.

The implementation matches the proposal, spec, design, and completed tasks for the targeted runtime slice:

- additive snake_case compatibility aliases resolve to the same implementations as the canonical PascalCase parity tools;
- alias resolution preserves validation, security policy, and backend-availability behavior;
- canonical-to-alias mapping is centralized in one source of truth;
- inventory and provider publication surfaces expose aliases deterministically without publishing duplicate tools or implying separate implementations.

All scoped verification commands for the owning Rust workspace (`clients/agent-runtime`) passed cleanly.

## Spec Compliance

### Requirement: Compatibility Alias Resolution for Search, Fetch, and Task Parity Tools

**Status:** PASS

Structural evidence:
- `clients/agent-runtime/src/tools/mod.rs`
  - `PARITY_TOOL_ALIASES`
  - `parity_alias_for(...)`
  - `canonical_tool_name_for_alias(...)`
- tool specs derive alias metadata from the centralized map, for example:
  - `clients/agent-runtime/src/tools/web_fetch.rs`
  - `clients/agent-runtime/src/tools/task_update.rs`
  - `clients/agent-runtime/src/tools/grep.rs`
- alias-aware execution path and canonical resolution are wired in runtime surfaces referenced by the apply report:
  - `clients/agent-runtime/src/agent/agent.rs`
  - `clients/agent-runtime/src/agent/dispatcher.rs`

Behavioral evidence:
- `tools::tests::parity_alias_mapping_round_trips`
- `agent::tests::turn_executes_tool_via_alias_then_returns`
- representative spec exposure test:
  - `grep_spec_exposes_snake_case_alias`

Scenario coverage:
- `glob` resolves to `Glob` behavior with the same result contract: PASS
- `task_update` resolves to `TaskUpdate` behavior with the same lifecycle semantics: PASS
- aliases do not point to separate implementations: PASS

### Requirement: Alias Resolution Must Preserve Validation, Permission, and Backend Semantics

**Status:** PASS

Structural evidence:
- `clients/agent-runtime/src/agent/dispatcher.rs`
  - policy path canonicalizes alias names through `canonical_tool_name_for_alias(...)`
- `clients/agent-runtime/src/tools/task_update.rs`
  - canonical tool execution still enforces `ToolOperation::Act` via the existing security boundary
- design/apply reports indicate no backend changes, only alias-aware routing and publication

Behavioral evidence:
- `agent::dispatcher::tests::test_risk_classification`
- `agent::tests::turn_executes_tool_via_alias_then_returns`

Scenario coverage:
- alias invocation cannot bypass canonical policy/risk evaluation: PASS
- alias invocation preserves backend availability and validation behavior: PASS

### Requirement: Canonical and Alias Tool Inventory Publication

**Status:** PASS

Structural evidence:
- tool specs include canonical `name` and additive `aliases`
- centralized alias source-of-truth avoids duplicated name tables
- agent/provider publication surfaces use deterministic canonical-first metadata

Behavioral evidence:
- `agent::dispatcher::tests::xml_prompt_instructions_publish_aliases_deterministically`
- `capabilities::tool_registration::tests::registry_from_tools_preserves_canonical_and_alias_metadata_without_duplicate_entries`
- `providers::compatible::tests::tool_specs_convert_to_openai_format_do_not_publish_aliases_as_duplicate_tools`
- `tools::tests::tool_spec_generation`

Scenario coverage:
- inventory surfaces publish canonical names and aliases deterministically: PASS
- publication does not imply aliases are separate tools: PASS
- provider formatting does not duplicate alias tools: PASS

## Design Conformance

**Status:** PASS

The implementation follows the major design decisions:

1. **Preserve PascalCase names as canonical** — followed
2. **Add snake_case names as compatibility aliases only** — followed
3. **Centralize mapping metadata in one source of truth** — followed
4. **Keep runtime security/permission/backend behavior unchanged** — followed
5. **Use canonical-first deterministic publication for inventory/docs/providers** — followed
6. **Avoid disruptive renames or widened capabilities** — followed

## Coverage Assessment

**Status:** ADEQUATE FOR SLICE

The executed verification covers the core behavior introduced by this slice:
- canonical↔alias round-trip mapping;
- runtime execution through aliases;
- policy/risk canonicalization for aliases;
- deterministic canonical-first publication in agent-facing prompt/inventory surfaces;
- registry and provider publication without duplicate alias tool entries;
- baseline tool spec generation remains intact.

Verification was scoped to the owning workspace per `openspec/config.yaml`.

## Regressions / Critical Issues

No regressions or critical issues were found in the scoped owning workspace during verification.

The alias compatibility slice appears additive and bounded as designed, with no evidence that aliases widen effective capabilities or bypass policy enforcement.

## Verdict

**PASS**

Reason:
- requirements are implemented in the runtime surfaces described by the change;
- design decisions were followed;
- tasks are complete;
- focused tests pass with adequate slice coverage;
- no regressions or critical issues were identified.

## Next Recommended

- This change is ready to be treated as verified.
- If desired, proceed to archive/close-out once broader process requirements are satisfied.
