Why a Doctor?
The Diagnostics skill is the self-knowledge of Passepartout. It answers "Is everything working?" by checking dependencies, environment variables, and LLM connectivity. Unlike the harness-level Doctor (which runs at boot and on CLI demand), this skill provides the Lisp-level diagnostic functions — defining what "healthy" means: which binaries must be present, which directories must exist, which API keys should be configured.
Phase A: Demand (Thinking)
Why a Doctor?
The Doctor transforms opaque startup failures into actionable engineering reports. It ensures the Brain never attempts to boot in a compromised state.
Detection Invariant
Binary detection must use shell probing (`which`) to account for varying `$PATH` inheritance between interactive and headless sessions.
Phase B: Contract
- (diagnostics-dependencies-check): probes PATH for every binary in
*diagnostics-binaries*. Returns T if all found, NIL if any missing. Side-effect: populates*doctor-missing-deps*. - (diagnostics-env-check): validates XDG directories exist. Returns T if all critical dirs present, NIL otherwise.
- (diagnostics-run-all &key auto-install): orchestrates 1-3. Returns
a plist with
:deps,:env,:llmkeys. Respects:auto-install nil.
Phase C: Implementation (Build)
