/dex-doctor — Full System Checkup

Diagnose everything, heal what's safe, guide the user through the rest.

Purpose

One honest answer to "is my Dex actually working?" Built against the failure modes found in the July 2026 audit: checks that never ran, checks that probed an easier path than the real feature, "off" reported as "broken", and background jobs that died silently for months.

When to Run

User asks "is everything working?", "what's broken?", "check my setup"
Something feels off — features silently not happening
After an update, migration, or machine change
User invokes /dex-doctor directly

Cardinal rules

Never report "off" as a problem. A feature the user never enabled is healthy. List it under "Off — that's fine", once, without nagging.
Never hide "couldn't check". If a probe failed to run, say so prominently. An unknown presented as a pass is how watchdogs go blind.
Never claim a heal worked without re-checking it.
Heal conservatively. Tier 1 only automatically. Tier 2 only after an explicit yes, one item at a time. Tier 3 is always the user's hands. Never delete or overwrite user data; never touch credentials.

Credential scan mode

Credential scanning is local and read-only. Inspect the worktree, index, approved Git common directory and primary object database, reachable refs, stashes, tags, and only archives the user explicitly selects. Report opaque redacted finding IDs plus explicit inspected and uninspected scope categories; never print paths or matched values. Existing .mcp.json is scan/report-only and remains byte-identical.

Render migration, security, active .mcp.json residual, and optional history hygiene as separate deterministic states using render_credential_status; do not paraphrase it. Provider revoke/rotate is always user-driven. Replacement health is read-only and runs
