Callers OR the skip reports and emit one combined stderr notice. * feat(cli): add zero trust command (trust/list/remove) * fix(review): key spec-draft trust on the original launch dir; cover trust CLI edge branches Spec-draft runs (zero exec --use-spec --worktree) passed the reassigned worktree path as trustRoot, dropping a trusted repo's project hooks (fail-closed, but breaks worktree-inheritance). Thread the captured pre-worktree trustRoot into execSpecDraftRun. Add tests for the trust 'remove' too-many-args and --help branches, and a resolveTrust comment noting the per-chokepoint check must not be hoisted to callers. * test(cli): end-to-end trust-gate coverage through agent.Run and exec --worktree Drives the real agent loop with a fake tool-calling provider so a project beforeTool hook actually fires (or is gated away) through production code: gate blocks a tool call via agent.Run, and --worktree / --use-spec --worktree key trust on the original launch dir. All three are load-bearing (RED when the gate or the trustRoot threading regresses). * style(cli): gofmt struct alignment in exec_spec.go * fix(workspacetrust): compare stored trust entries literally, no symlink re-resolution External adversarial review (codex) found a false positive: IsTrusted re-normalized stored entries on every check (Abs+EvalSymlinks), so a trusted path later replaced by a symlink to attacker content re-resolved to the new target and matched. Stored entries are already canonical (normalized once at Trust time); compare them as literals and only normalize the incoming query. Add a regression test for the symlink-retarget case. * feat(mcp): gate project-scoped MCP servers behind workspace trust Closes the P0 an external adversarial review (codex) found: project ./.zero/config.json stdio MCP servers spawned before the hook/plugin gate, an ungated arbitrary-execution path that could also self-trust the workspace. Add ExcludeProject to config.ResolveMCP (skips the project layer) and thread a fail-closed trust check into every MCP spawn site (exec, TUI setup+refresh, mcp tools list, mcp check); reporting sites stay ungated. Verified the sole server-command exec (mcp/client.go) is reachable only through the now-gated RegisterTools paths. * test(cli): cover default-mode beforeTool firing through the trust gate Assert a project beforeTool hook fires in the default auto and ask permission modes (not only under unsafe), and is blocked when the workspace is untrusted, so the gate is verified in the mode a normal run actually uses. * docs(cli): note MCP servers in zero trust help text and doc comment The gate covers project hooks, plugins, and MCP servers, but the help string and runTrust doc comment listed only hooks and plugins. * test(cli): make workspace-trust tests portable on macOS and Windows setTrustConfigRoot set HOME on darwin, but config.UserConfigDir is XDG-first there (=$HOME/.config), so tests wrote trust.json and user hooks.json where the code never read them; set XDG_CONFIG_HOME on every non-Windows platform instead. writeMarkerHook shells out to /bin/sh, absent on Windows, so its trusted-case marker never appeared; skip it there like writeMarkerHookScript already does. TestRunTrustAddThenList compared `trust list` output (canonicalized via EvalSymlinks) against the raw cwd, which diverges on the Windows runner's 8.3 short names (RUNNER~1 -> runneradmin); compare the resolved path, and add TestRunTrustListShowsCanonicalPath to exercise that via a symlink on any platform. * feat(cli): surface the project MCP skip in the workspace-trust notice Project MCP servers were dropped silently in an untrusted workspace: the trust notice covered hooks and plugins but not MCP, and app.go discarded the resolveTrust error. registerMCPToolsForWorkspace now returns a trustSkip, gated on a new projectMCPConfigExists check plus the previously-dropped store-read error, and emitTrustNotice is variadic so the exec, spec-draft, interactive, and `mcp tools list` paths all fold in the MCP skip. The skip drives the notice only; the gate stays on resolveTrust/excludeProject, so a trusted workspace is unaffected and an untrusted one still fails closed. * fix(cli): print zero trust --help to stdout with a success exit zero trust -h/--help/help routed usage to stderr with the usage exit code, unlike every other subcommand (mcp, sandbox, skills, cron, ...) which prints help to stdout and returns success. Align it; the unknown-subcommand path still writes to stderr with the usage exit code. * fix(cli): gate oauth MCP login and surface mcp-check trust notice Two project-scoped MCP activation sites were left outside the workspace trust gate. zero mcp oauth login loaded a project-defined OAuth server from an untrusted workspace and ran the full discovery/registration/token-exchange flow against its configured URL. Gate resolveOAuthServer with resolveTrust so an untrusted clone's ./.zero/config.json OAuth server is dropped before login, and emit the same one-line trust notice the other spawn sites use. zero mcp check already gated the project layer but discarded the trust-check result and never emitted the notice, so a gated project server read as a bare "not configured". Emit the notice on the not-found branch. The three remaining ungated resolveMCPConfig(cwd, false) sites (backends doctor/snapshot and the extensions listing) are enumeration-only and stay ungated. * test(cli): adapt MCP startup-skip tests to two-arg resolveMCPConfig --------- Co-authored-by: Kevin Codex <[email protected]>	2026-07-09 10:51:09 +08:00
3 people	363c0312d6	Skills & plugins: skill tool, skills loader, plugin manifests (#123) ... * Skills & plugins: skill tool, skills loader, plugin manifests Module of the runtime-core split (off main, after #119 tools merged). Clean extract — internal/skills is new; internal/plugins had no drift on main. No new deps. - internal/skills: loads */SKILL.md frontmatter from the skills dir (resolves its own XDG dir); no YAML dependency. - skill tool (internal/tools/skill.go), read-only, registered in CoreReadOnlyTools (so it's in the agent core + the MCP read-only default). Path-safe: it Load()s all skills and matches by exact name — it never builds a path from the model-supplied arg, so there is no traversal surface. knownToolNames gains "skill" for the specialist cross-package invariant; CoreReadOnlyTools count test bumped 4->5. - internal/plugins: plugin manifest metadata enrichment (Author/License/Keywords/Interface). FORWARD code — the cli plugin-loading wiring lands later. MCP hardening (nested-schema + hung-server fix) is a SEPARATE follow-up PR. build/vet/-race/full-suite + GOOS=windows build green. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> * Address #123 review (CodeRabbit): pointer metadata, skill schema alias, dir fallback, List test - plugins: Author/Interface are now *PluginAuthor/*PluginInterface so omitempty actually omits them — a non-pointer struct is never empty to encoding/json, so the old form emitted author:{}/interface:{} and changed the serialized shape of plugins that don't set them. parseAuthor/parseInterface return nil when all fields are empty; formatAuthor takes the pointer. (Major) - skill: schema now declares the 'skill' alias alongside 'name' (and drops strict Required) so the alias survives schema validators that reject unknown keys (AdditionalProperties:false); Run still enforces exactly-one-of via aliasedStringArg. (Major) - skills.DefaultDir: return "" instead of a relative ".local/share/..." path when neither XDG_DATA_HOME nor a resolvable HOME exists, so skills can't bind to the process CWD (load("") already no-ops). (Minor) - skills_test: TestListReturnsNamesAndDescriptions now asserts List strips Content so a listing can't silently leak full skill bodies. (Minor) build/vet/-race/full-suite + GOOS=windows build green. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> * Address #123 review (@Vasanthdev2004): confine skill SKILL.md to the skills root skill is a permission-allow read-only core/MCP tool, so the loader must not follow a symlinked SKILL.md (or skill dir) out of the skills root and become an arbitrary-file reader. load() now resolves the skills root via EvalSymlinks and, for each entry, resolves SKILL.md through symlinks and verifies the real path stays under the root (confineSkillPath); an escaping or unreadable path is skipped rather than read. Mirrors the grep/read_file confinement. Legit skills under a symlinked root (e.g. macOS /tmp) still load because the root is resolved too. Regression: TestLoadSkipsSymlinkedSkillFileEscapingRoot (a SKILL.md symlinked to a secret outside the root is skipped, not read). build/vet/-race/full-suite + GOOS=windows build green. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> * Address #123 re-review (CodeRabbit): reject non-regular SKILL.md, single-trim metadata - skills: confineSkillPath now Lstats the resolved path and skips non-regular targets (directory/FIFO/device/socket). A FIFO/device named SKILL.md (or an in-root symlink to one) would otherwise make os.ReadFile block indefinitely — skill is a permission-allow tool over a user-controlled dir. Regression: TestLoadSkipsNonRegularSkillFile (unix-tagged; mkfifo SKILL.md, asserts Load skips it within a timeout rather than hanging). (Major) - plugins: coerceMetaStringSlice trims each item once into a local var instead of calling strings.TrimSpace twice. (Nitpick) build/vet/-race/full-suite + GOOS=windows build green.
