    Interface AdapterCapabilities

    Which vigiles pillars/tiers a harness can drive — the capability matrix made executable (see docs/harnesses.md).

    🔴 KEPT AS A TYPE, NOT AS A FIELD. The flags used to sit in a nested capabilities object on the adapter, and that nesting is precisely what made the illegal state below expressible: TypeScript narrows a union by a discriminant on the object ITSELF, never by a.capabilities.x, so no shape of this interface could have tied harnessTesting: true to the presence of a driver. The flags are now discriminants on HarnessAdapter directly; this interface remains as the documented projection of them.

    referenceVerification is gone. It was true on every adapter and its type was the literal true — a field that can hold one value carries no information, and the conformance check for it could not fail.

    interface AdapterCapabilities {
        harnessTesting: boolean;
        shellHooks: boolean;
        subagents: boolean;

    harnessTesting: boolean

    Pillar 2 — deterministic harness tests + evals: the binary can be spawned and pointed at a mock model. Requires runtime + modelMock + harnessTestDriver. false for closed harnesses that route through a fixed backend (no BYOM): Cursor, Devin, Amp, Amazon Q — pillar-1-only adapters.

    shellHooks: boolean

    Hooks are shell processes speaking the exit-code/env block protocol — Claude Code, Codex, Crush. Requires hookProtocol. false when hooks are in-process code modules (OpenCode's TS plugins), so the run-hook unit tier and the HookProtocol port do not apply.

    subagents: boolean

    The harness has subagents — a named, model-dispatched delegate with its own tool contract and frontmatter (Claude Code's agents/*.md, OpenCode's agent surface). Gates the subagent-surface lint rules (subagent-tool-contract, subagent-frontmatter, untested-subagent, mcp-tool-resolves): where this is false those rules report n/a rather than running. false for Codex, whose [agents] TOML is a concurrency table, not a tool-contract file — a wholly different concept that deliberately shares the word.

    No port sits behind it, so it stays a plain flag on the base rather than becoming a discriminant of a union with nothing in its arms.
