ToolboxHook

Host-capability-aware engineering workflow orchestration designed to route work only through capabilities the host actually exposes.

Privatev0.2.1Fail-closedEvidence-driven

The product

Do not confuse a requested capability with a capability the host actually provides.

The project defines an engineering workflow from request through discovery, routing, execution, testing, verification and GitHub delivery.

Verified capabilities

What the workflow enforces

01

Capability discovery

Inspect available host capabilities before choosing an execution path.

02

Smallest relevant skills

Route work to the narrowest skill surface that can safely perform it.

03

Fail closed

Unsupported plugins, shell, Voice, Codex or GitHub access are not represented as available without evidence.

04

Evidence preservation

Approvals, tests, evidence and stop conditions remain part of the workflow contract.

05

Mutation verification

Read back resulting state after repository mutations rather than trusting a write response alone.

06

Release hygiene

Version 0.2.1 strengthens capability reporting, validation and release hygiene.

Workflow

Request → discover → capability check → route → execute → test → verify → GitHub delivery.

The orchestration contract is intentionally host-aware and evidence-driven.

Authority boundary: the workflow itself does not grant permissions. It can only use capabilities exposed by the host.
Mutation boundary: repository changes are followed by read-back verification so the claimed result matches actual state.

Engineering deep dive

Capability truth before execution.

A

Host introspection

Discover what the runtime can actually do before selecting tools or skills.

B

Fail-closed routing

Unsupported capabilities are not represented as installed or available.

C

Verification after mutation

Repository changes are checked by reading resulting state back from GitHub.

D

Release evolution

Versions 0.1.0, 0.2.0 and 0.2.1 represent explicit workflow evolution.

Evidence & status

Private engineering tool with a verified capability-aware contract.

Repository evidence identifies version 0.2.1 as the improved release, with capability reporting, validation, release hygiene and fail-closed behavior. The project explicitly avoids claims about capabilities the current host does not expose.
