Conversation
Register xAI's `grok` CLI as a supported tool with both skills and
commands, so `openspec init --tools grok` writes
`.grok/skills/openspec-*/SKILL.md` and `.grok/commands/opsx-<id>.md`.
Grok has no separate command subsystem: the loader that discovers
skills also scans `<vendor-dir>/commands/` and registers each Markdown
file there as a slash command. That scan does not recurse, so commands
are written flat — a nested `commands/opsx/<id>.md` would be skipped
rather than namespaced, leaving Grok users with no commands at all.
The filename therefore names the command, giving the `/opsx-<id>` form.
The adapter emits only `description`. Grok prefers a frontmatter `name`
over the file stem and normalizes it to `[a-z0-9-]`, while
`CommandContent.name` carries a display name ("OPSX: New"), so emitting
it would hand Grok a name OpenSpec does not control.
Also adds the missing `rovodev` id to the tool-ID list in
docs/supported-tools.md, on the same line this change edits: that list
and the one in docs/cli.md are maintained separately and had drifted.
Closes #1506

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Treat Grok Build as skills-only. xAI’s supported project paths include .grok/skills/ and .grok/plugins/; .grok/commands/ is not a project command source. openspec init --tools grok currently registers grokAdapter, writes .grok/commands/opsx-<id>.md, and advertises /opsx-*, so Grok cannot invoke the generated files. Remove the adapter-backed Grok registration and advertise the generated skills as /openspec-*.

Review feedback on #1851. Documents the `/openspec-propose` spelling that skills-only delivery produces for Grok, which the entry previously left to the general invocation table, and pins that behavior with an assertion that no command files are written in that mode. Also cites `.grok/commands/` to the shipping CLI's own symbols rather than asserting it. The published docs cover `skills/` only, so an automated review read the directory as unsupported; `skill_config_dirs()` returns `[".grok", ".agents", ".claude", ".cursor"]` and each is passed to `find_command_paths`, which scans `commands/` flat.

Thanks — one of these is right and one isn't. Minor (skills-only invocation): fixed in 347c9ee. The Grok footnote now spells out that skills-only delivery writes no command files and the skills are invoked as Major (treat Grok as skills-only): respectfully, this is incorrect —
pub fn skill_config_dirs(&self) -> Vec<&'static str> {
let mut dirs = vec![".grok", ".agents"];
...
pub const COMMAND_SUBDIR: &str = "commands";
/// Find `.md` files inside a `commands/` subdirectory.
pub fn find_command_paths(dir: &Path) -> Vec<PathBuf> {
scan_md_files(&dir.join(COMMAND_SUBDIR))
}and the caller, which walks each directory from the git root down to cwd: for config_dir_name in &config_dir_names {
let config_dir = dir.join(config_dir_name);
// Skills before commands: skills win name collisions.
for path in find_skill_paths(&config_dir)
.into_iter()
.chain(find_command_paths(&config_dir))So for every project directory, Beyond source reading, the generated tree behaves as documented end to end: Two points the finding does get at, which are handled:
Dropping the command adapter would leave Grok users with nothing at all under commands-only delivery, so I'm keeping it. |
Hardening pass on #1851. The docs and the adapter comment claimed Grok's flat command scan skips every vendor-compat directory, so a command could not register twice. That holds for `.claude/`, which nests commands under `opsx/`, and for `.agents/`, which no adapter writes commands into — but Cursor writes flat `opsx-<id>.md`, which the scan does find, and each of those roots can also hold an identical `openspec-*` skill. The copies differ only in the frontmatter each tool needs, so the outcome was never wrong; the stated reason was. Both places now describe the real shape. Also: - Adds the Grok row to `docs-lab/reference/supported-tools.md`, the source the published docs site renders. Without it the live page would not list the tool. - Orders the `--tools` id list in docs/supported-tools.md to match AI_TOOLS, so it is now identical to the copy in docs/cli.md. - Warns against naming your own Grok command `opsx-<workflow>.md`: Grok's flat scan means OpenSpec shares that directory with the user, and it owns those names. - Drops the upstream source citations from the user-facing footnote, which is the wrong altitude for it; they remain in the adapter header. - Asserts `available` on the Grok tool entry. Mutation testing found that flipping it to false removed Grok from the workset tool picker with a fully green suite, because the only test reading the field derives its expectation from AI_TOOLS itself. - Guards the command-stem loop against an empty command set, and adds grok to the flat-invocation tool list in command-references tests.

Closes #1506
Status
LGTM, ready for review. Build,
tsc --noEmit,eslint, andchangeset statusclean; 4,615 tests pass with only the two failures that already fail onmain(artifact-workflow"creates skills for Cursor tool",config-profile"confirmed project apply"). Verified againstmainbyte-for-byte: all 40 pre-existing tools generate identical files.What was missing / the motivation
#1506 asks whether OpenSpec can support Grok CLI. It could not —
grokwas not a registered tool, so.grok/projects were not detected and no skills or commands were generated.The tool the issue means is xAI's
grokCLI (docs.x.ai/build), which is active and has first-class skills support.What it does
Registers
grokwith both delivery surfaces:.grok/skills/openspec-*/SKILL.md/openspec-propose.grok/commands/opsx-<id>.md/opsx-proposeTwo properties of Grok's loader shaped the adapter. Both were read out of the shipping CLI's source, and both are failure modes that would have been silent:
The command scan does not recurse. Grok has no separate command subsystem — the loader that discovers skills also scans
commands/and turns each Markdown file into a slash command, via a single non-recursiveread_dir. Seven existing adapters nest commands underopsx/<id>.md; doing that here would have meant Grok registered zero commands, with no error. Commands are written flat, so the filename names the command — the/opsx-<id>form, whichinvocation.tsalready derives fromgetFilePathwith no list to edit.The adapter must not emit a frontmatter
name. Grok prefers frontmatternameover the file stem and normalizes it to[a-z0-9-].CommandContent.nameis a display name ("OPSX: New"), so emitting it would hand Grok a name OpenSpec does not control while docs, skills, and the getting-started hint all advertise the stem.Proof it works
Mutation-tested. 17 mutations applied one at a time; 14 were killed by the suite. Highlights:
opsx/opsx-prefixescapeYamlValuenameskillsDirat the shared.agentsrootrequiresIdeRestart: trueThree survived. One was a real gap and is now fixed (
available: falsesilently removed Grok from the workset tool picker, because the only test reading that field derives its expectation fromAI_TOOLSitself — it cancelled out). The other two are pre-existing repo-wide facts, not gaps in this PR:successLabelhas no consumer anywhere insrc/, and theadapters/index.tsbarrel re-export is unused for every adapter.Real CLI, not just unit tests:
openspec init --tools grok→ 6 skills + 6 commands, hint reads/opsx-propose "your idea", no stale/opsx:references anywhereboth→/opsx-propose,skills→/openspec-proposeand no command files,commands→ commands onlyopenspec updateis byte-idempotent; a bare.grok/auto-detects;--tools allincludes ittraeas a control: delivery transitions (both→skills→commands→both), profile transitions (core→custom→core),--force, half-deleted trees, and multi-tool installs all match it exactly. Six planted user files (config.toml, a custom command, a custom skill, a README, and two decoys) survived every run unmodified.Security: command ids are a closed set of literals and user config can only filter them, so nothing user-controlled reaches
getFilePath; every write and unlink goes through the existingassertPathWithinguard. 32 adversarial YAML inputs round-trip exactly under a strict parser. 11 hostile symlink/permission setups (including.groksymlinked to~/.ssh) were all refused cleanly, with nothing written or deleted outside the project and no stack traces — identical totraein every case.No regressions: built
mainin a separate worktree and byte-comparedinitoutput across all 40 existing tools — zero differences, re-verified after the hardening pass.Notes / nits
grokas skills-only and is approved, but has been conflicted and untouched since 2026-08-31. This PR is a superset built on currentmain; its author is credited as co-author. I have deliberately not closed it — that call is the maintainer's. Worth knowing if you do compare them: feat(grok): add skills-only support for grok build #1349's spec delta asserts "command-file generation SHALL be skipped because no Grok adapter is registered", which would be false on this branch. Its skills-only shape also leaves a Grok user ondelivery: commandswith zero artifacts, and deletes the skills they had on the nextupdate.codeassistant,command-code,zcode,junie,lingma,pi,kiro,bob) shipped with noopenspec/changes/proposal and no spec edits. This follows a registered adapter pattern with no architecture change, so it matches that precedent;command-generation's existing requirement that command references match the name a tool registers already covers the flat rewrite..grok/commands/is undocumented upstream. The published docs coverskills/only; the directory is read by the shipping CLI but not yet documented. The adapter header cites the exact symbols, and a pinned test guards the flat shape so an upstream change surfaces as a deliberate failure. Worst case if xAI removes it: the files are ignored, which is the status quo before this PR.docs/supported-tools.md's--toolsid list was missingrovodevand orderedcodeassistantdifferently from the copy indocs/cli.md; both lists now matchAI_TOOLSexactly. There is no test enforcing that parity, which is why it drifted — a worthwhile follow-up, but not this PR's job.escapeYamlValuedoes not escape U+2028/U+2029, which libyaml-based parsers treat as line breaks. Unreachable today (descriptions are compile-time constants) and it lives in the sharedyaml.tsused by every escaping adapter, so it belongs in its own change.🤖 Generated with Claude Code (Claude Opus 5)
