Conversation
…plying Adds a --dry-run option to 'openclaw doctor --fix' that shows what changes would be applied to the config without writing anything. Outputs a structured diff of proposed changes (additions, removals, modifications) and exits. The pendingChanges/candidate object already contains the full proposed change set before finalizeDoctorConfigFlow decides whether to write. --dry-run serializes the diff between cfg and candidate as a flat key-path comparison and emits it via note(), then returns shouldWriteConfig: false. This matches the pattern established by 'sessions cleanup --dry-run'. Changes: - src/commands/doctor.types.ts: add dryRun field to DoctorOptions - src/commands/doctor/finalize-config-flow.ts: dry-run diff logic + flattenObject helper - src/commands/doctor-config-flow.ts: pass dryRun through the flow - src/cli/program/register.maintenance.ts: wire --dry-run CLI flag - src/flows/doctor-health.ts: skip config-write assertion in dry-run mode - docs/cli/doctor.md: document --dry-run option - src/commands/doctor/finalize-config-flow.test.ts: 3 test cases for dry-run behavior Closes #79166

Security Review findings
Review detailsBest possible solution: Land one maintainer-approved Doctor preview path with a command-wide no-write boundary and redacted structured output, preserving useful tests/docs from this branch only if they fit that contract. Do we have a high-confidence way to reproduce the issue? Yes for source-level review: the patch routes dry-run through mutation-capable preflight/finalizer paths and prints raw config values. I did not execute Doctor because this review is read-only and the contributor still needs real patched CLI proof. Is this the best way to solve the issue? No. The requested feature is useful, but this branch implements it too late in the Doctor flow and creates an unredacted output contract; the safer solution is command-wide structured preview mode with redaction and no-write proof.

clawsweeper flagged that --fix --dry-run could still reach mutating repair paths in two ways: 1. runDoctorRepairSequence has real side effects (plugin installs via installPluginFromNpmSpec/ClawHub, index writes via writePersistedInstalledPluginIndexInstallRecords). It was called whenever shouldRepair=true, which includes the --fix --dry-run case. Fix: guard with `if (shouldRepair && !dryRun)`. 2. runWriteConfigHealth checks ctx.configResult.shouldWriteConfig || ctx.cfg !== ctx.cfgForPersistence. If any health contribution mutated ctx.cfg after the config flow returned shouldWriteConfig:false, the config write would fire anyway -- even in dry-run mode. Fix: add an authoritative early-return guard at the top of runWriteConfigHealth so dry-run can never write regardless of later cfg mutations. Together these make --dry-run a genuine read-only preview: config-level mutations collected before the repair sequence are still shown in the diff output; the repair sequence itself and all config writes are completely skipped.

…exclusions Expands the --dry-run option entry from a one-liner to a precise behavior spec: what is skipped (repair sequence, plugin installs, index state writes, config persistence), what diff is produced (pre-repair mutations: normalization, legacy migration, auto-enable), precedence over --fix/--repair, and Nix-mode compatibility. Adds a Notes entry documenting the two-layer write guard: the config flow returning shouldWriteConfig: false plus an authoritative early-return backstop in the write step that prevents late health contribution mutations from triggering a write in dry-run mode. Adds openclaw doctor --fix --dry-run to the Examples block.

Thanks for the contribution. I’m closing this branch because the proposed Doctor dry-run contract does not cover current repair paths, can expose raw configuration values, and the supplied proof does not exercise the patched behavior. The canonical dry-run request remains open for a safer, complete implementation. |
Summary
Adds
--dry-runtoopenclaw doctor --fixso operators can preview proposed config changes before committing to them. The flag runs the full diagnostic pipeline, collects all proposed mutations, outputs a structured diff, and exits without writing.Closes #79166.
Motivation
openclaw doctor --fixis the most common maintenance command, but it applies changes without preview. There is no way to see what--fixwould do before it does it.sessions cleanupalready has--dry-run— this brings parity to the doctor config path.We have experienced
doctor --fixsilently stripping custom config fields that were valid and intentional but not in the expected schema. A--dry-runflag would have prevented each of those incidents.Design
The
pendingChangesobject andcandidateconfig already contain the full proposed change set beforefinalizeDoctorConfigFlowdecides whether to write.--dry-runleverages this existing plumbing:dryRunis true, the config preflight runs withrepairPrefixedConfig: trueso legacy migration and normalization steps populatecandidate.finalizeDoctorConfigFlowcomparescfg(current) againstcandidate(proposed) using a flat key-path diff.note()as+(added),-(removed),~(modified) lines.shouldWriteConfig: false— no config mutation occurs.--dry-runtakes precedence over--repair/--fixif both are specified.Security fixes (post-submission, commit eabb075)
After clawsweeper's review identified two write-path gaps, both were fixed:
Gap 1 —
runDoctorRepairSequenceside effects in dry-run mode.The repair sequence has real filesystem side effects:
installPluginFromNpmSpec/installPluginFromClawHub(package installs) andwritePersistedInstalledPluginIndexInstallRecords(index state writes). It was called whenevershouldRepair === true, which includes--fix --dry-run. Fix:if (shouldRepair && !dryRun)— repair sequence skipped entirely in dry-run. Config-level diff is still produced from pre-repair mutations (normalization, legacy migration, auto-enable).Gap 2 —
runWriteConfigHealthcould write pastshouldWriteConfig: false.runWriteConfigHealthwrites whenctx.configResult.shouldWriteConfig || ctx.cfg !== ctx.cfgForPersistence. If any health contribution mutatedctx.cfgafter the config flow returnedshouldWriteConfig: false, the write would fire anyway.

openclaw doctor --fixapplies config changes without preview. No--dry-runor--previewflag exists. This adds--dry-runto show proposed changes without writing. Filed as [Feature] Doctor dry-run / diff mode #79166.tsc --strict --noEmiton the new code paths, zero errors). Ranopenclaw doctor --non-interactiveon the live gateway to confirm current doctor flow is unaffected. Traced the full flag wiring path: CLI registration (register.maintenance.ts) →DoctorOptionstype →loadAndMaybeMigrateDoctorConfig→finalizeDoctorConfigFlowdry-run branch.TypeScript type verification (standalone, our new code extracted):
The
dryRunflag path infinalizeDoctorConfigFlowproduces a flat key-path diff ofcfgvscandidateand returnsshouldWriteConfig: false. WhenpendingChangesis true anddryRunis true, the diff is emitted vianote()with title "Dry run — proposed changes (not applied)". When no changes exist, "No config changes detected." is emitted.--non-interactive). TheassertConfigWriteAllowedInCurrentModeguard is correctly skipped whendryRunis true (so--dry-runwill also work in Nix mode where config is immutable). Three new test cases cover the dry-run branch: changes present, no changes, and dry-run overriding repair mode.pnpm build && pnpm check && pnpm test— the@openclaw/fs-safegit-hosted dependency fails its prepack script in a fresh clone on macOS arm64. This is a pre-existing environment issue with the git-hosted tarball, unrelated to this change. CI handles the full suite.CI note
Three CI checks (
build-artifacts,build-smoke,check-additional) are failing due to a pre-existing upstream i18n drift inui/src/ui/chat/grouped-render.ts— a hardcoded"Tool output"string not in locale files. None of our changed files touch the UI or i18n surface. All 81 checks covering our actual changes passed.Tests
