From 6f2ba4833f8c2e5691098fb940cf7d7eefb52ddf Mon Sep 17 00:00:00 2001 From: shanglei Date: Wed, 13 May 2026 11:27:22 +0800 Subject: [PATCH 01/19] feat(extension): introduce Plugin / Hook framework with command pruning Add a single public extension contract under extension/platform: integrators implement the Plugin interface and register Observers, Wrappers, Lifecycle handlers, and pruning Rules through the Registrar in one Install call. Command pruning: - Rule (Allow / Deny / MaxRisk / Identities) with doublestar globs - 4-axis AND evaluation, parent-group aggregation, unknown-risk allow - Sources: Plugin.Restrict (single-rule) and ~/.lark-cli/policy.yml - Plugin path is fail-closed (envelope on rule error / multiple Restrict); yaml path is fail-open (warning, CLI continues) - strict-mode stubs now also write the denial annotation so the hook layer's denial guard physically isolates Wrap chains on them - HOME path never leaked through policy_source label Hook framework: - Observer (panic-safe, Before/After), Wrapper (middleware, may short-circuit via AbortError), Lifecycle (Startup + Shutdown only) - Recover guards every plugin entry point: Capabilities(), Install(), Wrapper factory composition AND inner Handler, Lifecycle handlers - namespacedWrap copies AbortError so a plugin's package-level sentinel is never mutated across concurrent invocations - Selector unknown-risk uniform: ByExactRisk / ByWrite / ByReadOnly never match unannotated commands; safety-side hooks opt in via ByWrite().Or(ByUnknownRisk()) Bootstrap orchestration (cmd/build.go + cmd/policy.go): - InstallAll uses a staging Registrar + atomic commit - FailClosed plugin install / Plugin.Restrict conflict / Startup handler failure each install a structured envelope guard at every dispatch path - walkGuard neutralises every cobra bypass we know of (PersistentPreRunE first-wins, ValidateArgs, ParseFlags, legacyArgs, __complete / __completeNoDesc, non-runnable groups, required-arg subcommands) - cmd/root.go::Execute calls hook.Emit(Shutdown, runErr) after rootCmd.Execute; isCompletionCommand skips both __complete and __completeNoDesc so Tab completion never triggers Shutdown handlers Capabilities consistency: - Restricts=true must declare FailurePolicy=FailClosed - RequiredCLIVersion (semver constraint) is validated against build.Version; a malformed constraint is treated as untrusted-config and aborts unconditionally, regardless of FailurePolicy (DEV builds included) JSON envelope contract: - error.type closed enum: pruning / strict_mode / hook / plugin_install / plugin_conflict / plugin_lifecycle - reason_code closed enums per type, all referenced by structured tests Bootstrap surfaces (new user commands): - lark-cli config policy show -- JSON view of the active Rule + source - lark-cli config policy validate -- parse + schema + glob check, no apply Coverage: - extension/platform: every public type has a unit test - internal/{pruning,hook,platformhost,policydecision,cmdmeta}: full coverage of denial guard isolation, AbortError sentinel safety, observer panic safety, lifecycle error/panic typing, staging atomic rollback - cmd/plugin_integration_test.go: end-to-end through buildInternal with synthetic and real command trees - cmd/install_guard_test.go: walkGuard covers auth / config / __complete / __completeNoDesc / non-runnable parents --- cmd/build.go | 73 ++- cmd/config/config.go

Cobra's dispatch order means several pre-RunE gates can fire BEFORE the stub's RunE ever runs: 1. Args validator: shortcut commands often declare cobra.NoArgs. With DisableFlagParsing=true the user's `--doc xxx --mode append` looks like positional args, so ValidateArgs surfaces a usage error instead of the pruning / strict_mode envelope. Observer hooks also miss the dispatch entirely. 2. Parent PersistentPreRunE: cmd/auth/auth.go declares a PersistentPreRunE that returns external_provider when env credentials are set. Cobra's "first PersistentPreRunE wins walking up from the leaf" then short-circuits with external_provider instead of the leaf's denial envelope. Both stubs now also set: - Args = cobra.ArbitraryArgs (bypass gate 1) - PersistentPreRunE = no-op leaf hook (bypass gate 2) - PreRunE / PreRun / PersistentPreRun = nil (defensive) Effect: dispatch reaches the wrapped RunE, observers fire, the real pruning / strict_mode envelope is emitted regardless of credential provider or flag count.

Before this change, platform.ByDomain("docs") never matched any command: the domain annotation was unset across the entire shortcut tree, so the selector's d != "" guard always failed and risk-style selectors silently degraded to no-op. The SetDomain call is placed AFTER the create-or-reuse branch so it fires whether the service command was freshly created here or had already been added by cmd/service/service.go's OpenAPI auto- registration (which runs first and creates im, drive, calendar, etc.). Without this placement only pure-shortcut services like docs would have been tagged.

It also duplicated `detail.layer`, and forced consumers to branch on two values for the same conceptual error ("a command was denied by policy"). Collapse both into a single semantic type "command_denied". The enforcement layer ("pruning" / "strict_mode") is preserved in `detail.layer` so debugging and per-layer diagnostics still work. --- cmd/auth/login.go | 2 +- cmd/policy_test.go | 4 ++-- cmd/prune.go | 2 +- cmd/root_integration_test.go | 12 ++++++------ internal/cmdutil/factory.go | 2 +- internal/hook/install.go | 5 +++-- internal/pruning/aggregation_test.go | 8 ++++---- internal/pruning/apply.go | 12 +++++------- 8 files changed, 23 insertions(+), 24 deletions(-) diff --git a/cmd/auth/login.go b/cmd/auth/login.go index 6a27ee6cf..a519ccc0b 100644 --- a/cmd/auth/login.go +++ b/cmd/auth/login.go @@ -50,7 +50,7 @@ For AI agents: this command blocks until the user completes authorization in the browser.

Both gaps let an unannotated or typo'd write command slip past an "agent read-only" pruning rule. Engine now denies before any other axis when a Rule is registered: - reason_code "risk_not_annotated" for commands with no risk - reason_code "risk_invalid" for commands whose risk is outside the read | write | high-risk-write taxonomy (e.g. typo "wrtie") Main-flow is preserved: a nil Rule still returns Allowed=true unconditionally, so a CLI with no pruning plugin behaves identically to before. ByUnknownRisk() is removed from the public surface since the Unknown state is no longer reachable through risk-based selectors when any Rule is active; safety-side widening composition is no longer needed. --- extension/platform/doc.go | 2 +- extension/platform/selector.go | 40 +++-------- extension/platform/selector_test.go | 32 ++------- extension/platform/view.go | 9 ++- internal/cmdmeta/meta.go | 11 +-- internal/pruning/aggregation_test.go | 20 ++++++ internal/pruning/engine.go | 44 +++++++----- internal/pruning/engine_test.go | 104 ++++++++++++++++++++++++--- 8 files changed, 168 insertions(+), 94 deletions(-) diff --git a/extension/platform/doc.go b/extension/platform/doc.go index d763410a9..f68a9dbc6 100644 --- a/extension/platform/doc.go +++ b/extension/platform/doc.go @@ -18,7 +18,7 @@ // - Observer - side-effect-only callback, panic-safe, runs Before / After RunE // - Wrapper - middleware that can short-circuit via AbortError // - LifecycleHandler - reacts to Startup / Shutdown / etc. (LifecycleEvent + When) -// - Selector - chooses which commands a hook applies to (ByDomain / ByWrite / ByUnknownRisk / And / Or / Not, etc.); unknown-risk commands never match risk-based selectors, opt in via ByUnknownRisk() +// - Selector - chooses which commands a hook applies to (ByDomain / ByWrite / ByReadOnly / ByExactRisk / And / Or / Not, etc.) // - Handler - the inner "run the command" function Wrappers compose around // - Invocation - per-call context passed to handlers (Cmd view + DeniedByPolicy / StrictMode / Identity) // - AbortError - structured short-circuit error from a Wrapper; framework namespaces HookName diff --git a/extension/platform/selector.go b/extension/platform/selector.go index 514e97910..f53298c3e 100644 --- a/extension/platform/selector.go +++ b/extension/platform/selector.go @@ -58,19 +58,14 @@ func ByIdentity(id string) Selector { } } -// All risk-based selectors below share a single contract: **commands -// without a risk_level annotation (unknown) NEVER match.** Many commands -// in the repo are unannotated; a "unknown = match" semantics would force -// safety / approval plugins to silently cover the whole CLI surface, -// punishing integrators rather than helping.

Plugins compile in via blank import; there is no dynamic loading and no RPC isolation. Public SDK (extension/platform): - Plugin interface (Name / Version / Capabilities / Install). - Registrar verbs: Observe, Wrap, On, Restrict. - Hook types: Observer (side-effect, panic-safe, fires Before/After RunE), Wrapper (middleware, may short-circuit via AbortError), LifecycleHandler (Startup / Shutdown), Selector with nil-safe And/Or/Not composition. - Risk / Identity are defined string types with closed taxonomies; ParseRisk / ParseIdentity convert raw strings with the absent-vs-invalid distinction the engine relies on. - Builder ergonomic constructor (NewPlugin().Observer().Wrap() ...MustBuild()) that enforces name/hookName grammar, hookName uniqueness, and the Restrict ↔ FailClosed pairing regardless of call order. - Invocation is a read-only interface; the framework's concrete invocation type lives in internal/hook so plugins cannot fabricate denial / strict-mode / identity state. Args() returns a defensive copy on every call so hook mutation cannot leak into the original RunE. - CommandDeniedError + AbortError carry structured fields for the closed `command_denied` / `hook` envelope contract. - ResetForTesting gated behind //go:build testing. - README + godoc examples (Observer / Wrapper / Restrict) + two runnable example forks (audit-observer, readonly-policy). Host (internal/platform, internal/hook, internal/cmdpolicy): - InstallAll: staged plugin registration with atomic commit, panic isolation, FailOpen / FailClosed semantics, RequiredCLIVersion semver check, single-Restrict invariant, duplicate-plugin-name detection. - hook.Install wraps every runnable cmd.RunE with: Before observers (panic-safe) → denial guard → composed Wrap chain → original RunE → After observers (always fire, even on err). Denied commands physically bypass the Wrap chain so a plugin Wrapper cannot suppress or rewrite a denial; observers still see the attempt for audit. - Recover shim around plugin Wrappers converts panics (including the factory call) into a structured `hook` envelope with reason_code=panic; namespacing shim attributes AbortError to the namespaced hook name. - cmdpolicy (renamed from internal/pruning) is the user-layer command policy engine: walks the cobra tree, evaluates each runnable command against a Rule's four-axis filter (Allow / Deny / MaxRisk / Identities), produces parent-group aggregate denials, and installs denyStubs. Rule.AllowUnannotated opts out of the unannotated-deny gate for gradual adoption; risk_invalid typos always deny with an edit-distance "did you mean" suggestion. - Strict-mode stub in cmd/prune.go composes the shared detail.* / wrapped CommandDeniedError shape via cmdpolicy helpers (BuildDenialError / CommandDeniedFromDenial / DenialDetailMap), so command_denied envelopes from strict-mode and user-layer policy carry the same closed-enum fields (detail.layer / reason_code / policy_source). The historical short Message + independent Hint are preserved unchanged. - cmdpolicy/yaml: structural parsing of ~/.lark-cli/policy.yml with KnownFields strict mode, including allow_unannotated. - `config policy show` / `config policy validate` and the plugin inventory diagnostic surface the resolved Rule (allow, deny, max_risk, identities, allow_unannotated) and the hook contributions per plugin. Envelope contract (docs/extension/reason-codes.md): - error.type is a closed set: command_denied, hook, plugin_install, plugin_conflict, plugin_lifecycle. - reason_code is a closed enum per error.type, dispatched on by external agents and CI integrations. - detail.layer = "policy" | "strict_mode" attributes the rejection. Build / CI: - Makefile unit-test / vet / coverage and ci.yml fast-gate + unit-test + coverage now pass -tags testing so register_testing.go is visible; ./extension/... is in the package list so the SDK's own tests actually run. - fmt-check and examples-build Makefile targets. - bmatcuk/doublestar/v4 added as a direct dependency for `**` glob matching in Rule.Allow / Rule.Deny. Author-facing material: - docs/extension/ (quickstart, plugin-author-guide, reason-codes) is provided in the working tree but kept out of git tracking per repo convention (.gitignore covers docs/).

Plugins compile in via blank import; there is no dynamic loading and no RPC isolation. Public SDK (extension/platform): - Plugin interface (Name / Version / Capabilities / Install). - Registrar verbs: Observe, Wrap, On, Restrict. - Hook types: Observer (side-effect, panic-safe, fires Before/After RunE), Wrapper (middleware, may short-circuit via AbortError), LifecycleHandler (Startup / Shutdown), Selector with nil-safe And/Or/Not composition. - Risk / Identity are defined string types with closed taxonomies; ParseRisk / ParseIdentity convert raw strings with the absent-vs-invalid distinction the engine relies on. - Builder ergonomic constructor (NewPlugin().Observer().Wrap() ...MustBuild()) that enforces name/hookName grammar, hookName uniqueness, and the Restrict ↔ FailClosed pairing regardless of call order. - Invocation is a read-only interface; the framework's concrete invocation type lives in internal/hook so plugins cannot fabricate denial / strict-mode / identity state. Args() returns a defensive copy on every call so hook mutation cannot leak into the original RunE. - CommandDeniedError + AbortError carry structured fields for the closed `command_denied` / `hook` envelope contract. - ResetForTesting gated behind //go:build testing. - README + godoc examples (Observer / Wrapper / Restrict) + two runnable example forks (audit-observer, readonly-policy). Host (internal/platform, internal/hook, internal/cmdpolicy): - InstallAll: staged plugin registration with atomic commit, panic isolation, FailOpen / FailClosed semantics, RequiredCLIVersion semver check, single-Restrict invariant, duplicate-plugin-name detection. - hook.Install wraps every runnable cmd.RunE with: Before observers (panic-safe) → denial guard → composed Wrap chain → original RunE → After observers (always fire, even on err). Denied commands physically bypass the Wrap chain so a plugin Wrapper cannot suppress or rewrite a denial; observers still see the attempt for audit. - Recover shim around plugin Wrappers converts panics (including the factory call) into a structured `hook` envelope with reason_code=panic; namespacing shim attributes AbortError to the namespaced hook name. - cmdpolicy (renamed from internal/pruning) is the user-layer command policy engine: walks the cobra tree, evaluates each runnable command against a Rule's four-axis filter (Allow / Deny / MaxRisk / Identities), produces parent-group aggregate denials, and installs denyStubs. Rule.AllowUnannotated opts out of the unannotated-deny gate for gradual adoption; risk_invalid typos always deny with an edit-distance "did you mean" suggestion. - Strict-mode stub in cmd/prune.go composes the shared detail.* / wrapped CommandDeniedError shape via cmdpolicy helpers (BuildDenialError / CommandDeniedFromDenial / DenialDetailMap), so command_denied envelopes from strict-mode and user-layer policy carry the same closed-enum fields (detail.layer / reason_code / policy_source). The historical short Message + independent Hint are preserved unchanged. - cmdpolicy/yaml: structural parsing of ~/.lark-cli/policy.yml with KnownFields strict mode, including allow_unannotated. - `config policy show` / `config policy validate` and the plugin inventory diagnostic surface the resolved Rule (allow, deny, max_risk, identities, allow_unannotated) and the hook contributions per plugin. Envelope contract (docs/extension/reason-codes.md): - error.type is a closed set: command_denied, hook, plugin_install, plugin_conflict, plugin_lifecycle. - reason_code is a closed enum per error.type, dispatched on by external agents and CI integrations. - detail.layer = "policy" | "strict_mode" attributes the rejection. Build / CI: - Makefile unit-test / vet / coverage and ci.yml fast-gate + unit-test + coverage now pass -tags testing so register_testing.go is visible; ./extension/... is in the package list so the SDK's own tests actually run. - fmt-check and examples-build Makefile targets. - bmatcuk/doublestar/v4 added as a direct dependency for `**` glob matching in Rule.Allow / Rule.Deny. Author-facing material: - docs/extension/ (quickstart, plugin-author-guide, reason-codes) is provided in the working tree but kept out of git tracking per repo convention (.gitignore covers docs/).
