Summary

  • rt skills compile / check: pure compile core (slots+body type, fill modes, vendoring with exclusions, deterministic output, reference lint incl. descriptions), source/manifest IO with attachments/ fallbacks, stale-cache-entry tolerance
  • rt skills surface (list / set / apply / fzf palette with delta+confirm gate) and surface.jsonc enforcement (placement verification, internal-verb skip, internal-roster errors)
  • Shipped downstream: claimview pack fully migrated to compiled skills (0.4.x), mattstack 0.6.x, mr-board --skill-path launch

Specs: claimview-tools docs/specs/2026-08-20-compiled-skills-and-visibility-v2.md; plans: docs/plans/2026-08-20-compiled-skills-v1-core.md + 2026-08-21-surface-ratchet.md.

Test plan

  • bun test lib commands packages 1676 pass / 0 fail; bunx tsc --noEmit clean on the branch head
  • git merge-tree against main is clean; branch was developed stacked on rt-50-keys-wave but has zero dependency on it

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds skill source loading, deterministic skill compilation, freshness checking, public or internal surface management, interactive palette support, CLI registration, and extensive unit, integration, and command tests.

Changes

Skills compilation and surface management

Layer / File(s)Summary
Skill source contracts and loading
lib/skills/types.ts, lib/skills/sources.ts, lib/skills/__tests__/sources.test.ts
Adds typed skill sources and loaders for plugins, pipeline steps, attachments, rosters, manifests, surface configuration, and invocable skills.
Skill compilation and output validation
lib/skills/compile.ts, lib/skills/__tests__/compile.test.ts
Adds slot binding, frontmatter and body generation, file vendoring, reference rewriting, internal-skill inlining, linting, and deterministic compilation results.
Compile and freshness-check commands
commands/skills.ts, commands/__tests__/skills.test.ts, lib/command-tree-def.ts, lib/module-registry.ts
Adds skills compile and skills check, including argument handling, dry runs, output replacement, stale-output detection, clean errors, and command registration.
Surface registry and interactive workflows
commands/skills.ts, commands/__tests__/skills-surface.test.ts, lib/fzf.ts
Adds surface listing, status changes, directory moves, persistence, apply workflows, palette decisions, interactive fallback behavior, and recompilation.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk:🟠 High · up to 1ba97

The new compiled-skills and surface workflows still contain a high-impact malformed-input case that can delete an entire skills directory, along with command paths that can silently no-op, report stale state incorrectly, or leave configuration and filesystem state inconsistent. The PR is not merge-ready until these destructive and integration failures are fixed.

findDefaultManifest matches the team name as a bare substring.

header.includes(team) matches any occurrence in the leading comment block. A short team name such as t or cv matches unrelated headers, and the command then compiles against the wrong bindings without any warning. The tie-break only compares mtime, so the wrong file can win outright.

Match the provenance token instead, for example <team>@<team> as the generator writes it, or require a word boundary.

Inline comments:
In `@commands/__tests__/skills-surface.test.ts`:
- Around line 293-304: Update the non-TTY test for skillsSurface to explicitly
stub process.stdin.isTTY as false before invoking the command, then restore the
original stdin TTY state during cleanup so the test always exercises the
fallback path without depending on the developer’s terminal environment.
In `@commands/__tests__/skills.test.ts`:
- Around line 150-154: Update the afterEach cleanup in
commands/__tests__/skills.test.ts lines 150-154 and
commands/__tests__/skills-surface.test.ts lines 50-53 to assign process.exitCode
= 0 instead of undefined, ensuring exit-code state cannot leak between tests.
In `@commands/skills.ts`:
- Around line 689-710: Update the palette computation around computeRows and
decidePaletteAction so public names already present in surface.public but absent
from allNames are preserved or represented in resultRows. Ensure the preview
includes any resulting removal or retention decision, and ensure
writeSurfaceConfig does not silently drop those unrepresented previous entries.
- Around line 336-357: Update skillsCheck around the resolved.roster loop to
treat a missing outDir for any public verb as stale and report it instead of
skipping the verb. When outDir exists, compare the compiled result.files paths
with the actual directory contents, including recursively discovered files, and
mark unexpected orphan files as stale alongside missing or differing emitted
files so the check matches writeCompiledVerb output.
In `@docs/superpowers/plans/2026-08-21-home-repo-reroot.md`:
- Around line 64-75: Update the home initialization test covering runHomeInit to
include the downstream SOPS setup. Assert SOPS_YAML_PATH resolves to
user/.sops.yaml via renderSopsYaml, and verify the initialization path preserves
the new SOPS working-directory contract alongside the existing lib/home and
lib/secrets expectation updates.
- Around line 79-80: The writeMachineKey step must treat an existing empty
machine-key file as missing, rather than skipping solely because the path
exists. Update the machine-key presence probe and writeMachineKey skip condition
to require a non-empty valid key, while preserving the existing behavior for
valid persisted keys.
- Around line 79-87: Replace the boolean skillsSymlinkPresent probe in the
HomeState plan state with a discriminated path-state result that distinguishes
missing, correct symlink, incorrect symlink, and real file, including the
symlink target where applicable. Update the plan-builder tests to cover every
state, ensure writeSkillsSymlink skips only the correct symlink, repairs an
incorrect symlink, creates a missing link, and marks a real file as blocked
without overwriting it.
In `@docs/superpowers/specs/2026-08-21-home-repo-reroot.md`:
- Around line 42-48: Update
docs/superpowers/specs/2026-08-21-home-repo-reroot.md lines 42-48 to define the
machine-key override as exactly one validated path segment and require
non-missing-file read errors to surface rather than silently falling back.
Update docs/superpowers/plans/2026-08-21-home-repo-reroot.md lines 39-55 to
require both path modules to implement and test the identical validation and
error semantics.
- Line 12: Update the fenced repository tree layout block in the documentation
to specify the text language, resolving the MD040 lint violation while
preserving its contents.
- Around line 142-149: Make writer quiescence an explicit mandatory preflight
gate before any destructive live migration steps: stop and verify daemon and
snapshot writers before moving, swapping, or deleting repository state. Update
docs/superpowers/specs/2026-08-21-home-repo-reroot.md lines 142-149 to state
this gate before the backup and migration sequence, and update
docs/superpowers/plans/2026-08-21-home-repo-reroot.md lines 101-103 to require
the same condition for the orchestrator-only migration task.
In `@lib/command-tree-def.ts`:
- Around line 777-786: Add the missing Name, Public, Internal, and Manifest
arguments to the surface node alongside Mode, Team, and Dry run, using the
existing skillsSurface and parseSurfaceFlags option conventions so
generated-tree users can satisfy set and apply requirements.
In `@lib/skills/compile.ts`:
- Line 10: Update SKILL_DIR_PATH_RE handling and the related emitted-path lookup
to remove trailing sentence punctuation from the captured relative path before
checking emittedPaths, while preserving valid punctuation within paths.
- Line 9: Update REGISTERED_NAME_RE and the compileSkill lint flow to recognize
any valid team-prefixed token, then filter matches by membership in the provided
roster and internalRoster sets. Remove the hardcoded team alternation so
computeInternalRoster and both lintReferences and lintInternalRoster enforce
tokens for arbitrary --team values.
- Around line 30-32: Update yamlQuote to escape newline and other control
characters required by YAML double-quoted scalars, while preserving the existing
backslash and quote escaping so descriptions from stubs.jsonc always produce
valid single-line frontmatter values.
In `@lib/skills/sources.ts`:
- Around line 295-313: Update assertSafeVerbName, used by readVerbRoster, to
reject empty and "." names in addition to path separators and "..", preventing
skill output cleanup from targeting the pack’s skills directory. Validate each
stub’s engine and description during readVerbRoster and raise a clear usage
error for missing or invalid values before compilation. Preserve valid roster
entries and ensure both writeCompiledVerb and the internal-verb skip path
receive only validated definitions.

### Task 2: sops triple moves to user/-rooted

**Files:**
- Modify: `lib/home/age-key.ts` (`renderSopsYaml` :122-124 — `path_regex: user/secrets/.*` → `secrets/.*`)
- Modify: `lib/secrets/store.ts` (`buildSecretsSpawnOptions` :340-348 — `cwd: mattstackHome()` → `join(mattstackHome(), "user")`; the `--filename-override user/secrets/<domain>.json` construction (~:222-230 + the header comment :10) → `secrets/<domain>.json`)
- Test: existing suites for both modules — update expectations; the store suite's cwd-pin unit test asserts the new cwd

The three values are cwd-coupled: sops resolves `.sops.yaml` and its `path_regex` relative to cwd, and the filename-override must match the regex or sops matches NO creation rule (silent wrong-recipient). All three change in this one task, never separately.

- [ ] RED: renderSopsYaml output equals the new literal; spawn options cwd = `<mattstackHome>/user`; filenameOverride = `secrets/<domain>.json`
- [ ] Implement; full gates green
- [ ] Commit

Include the init-level SOPS test in this task.

The supplied commands/__tests__/home.test.ts, Lines 181-189, asserts that runHomeInit backfills SOPS_YAML_PATH with renderSopsYaml. The plan lists lib/home/__tests__/ but not this downstream test. Update it for user/.sops.yaml and exercise the new init path and SOPS working-directory contract.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

The surface node cannot express set's required flags.

skillsSurface rejects set without --public or --internal, and parseSurfaceFlags also accepts --manifest. The node declares only Mode, Team, and Dry run. A user who drives this command through the generated tree UI cannot supply the name plus --public/--internal, so set always fails with "set requires --public or --internal". runApply delegates to skillsCompile, which needs --manifest when auto-discovery does not resolve, and that flag is missing here too.

Add Name, Public, Internal, and Manifest args, or split set into its own subcommand node.

Trailing sentence punctuation is captured into the linted path.

SKILL_DIR_PATH_RE stops only at whitespace and "'). Prose such as See ${CLAUDE_SKILL_DIR}/ci-config.json.yieldsci-config.json.asrelPath, which is not in emittedPaths`. The compiler then emits a false "not an emitted file" warning.

Strip trailing punctuation before the lookup.

- const relPath = full.slice(`${CLAUDE_SKILL_DIR_TOKEN}/`.length);+ const relPath = full.slice(`${CLAUDE_SKILL_DIR_TOKEN}/`.length).replace(/[.,;:!?]+$/, "");

yamlQuote does not escape newlines or control characters.

A verb description comes from stubs.jsonc, and JSON strings can contain \n. The current escape only handles \ and ", so a description with a newline emits a double-quoted scalar broken across two lines. The resulting SKILL.md frontmatter no longer parses as YAML for every downstream reader.

🐛 Proposed fix

- return `"${value.replace(/\\/g, "\\\\").replace(/"/g, '\\"')}"`;+ const escaped = value+ .replace(/\\/g, "\\\\")+ .replace(/"/g, '\\"')+ .replace(/\n/g, "\\n")+ .replace(/\r/g, "\\r")+ .replace(/\t/g, "\\t");+ return `"${escaped}"`;

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Reject empty and dot verb names too.

assertSafeVerbName blocks /, \ and .., but it accepts "" and ".". Both resolve join(packDir, "skills", name) to <packDir>/skills. writeCompiledVerb then calls rmSync(outDir, { recursive: true, force: true }) on that directory, which deletes every compiled skill in the pack. The internal-verb skip path in commands/skills.ts has the same rmSync.

Also consider validating def.engine and def.description. A stub entry without description reaches yamlQuote(undefined) in lib/skills/compile.ts and throws a TypeError instead of a clean usage error.

Assert the exact header comment text, and stop the name/path lint from
scanning the compiler's own seam/header comment lines so an internal
attachment's non-invocable binding no longer self-triggers a warning;
author prose is still fully linted.

AttachmentSource gains registered: boolean. Internal attachments
(registered: false) inline as before: seam comment + body. Registered
top-level skills (registered: true) stay singly-canonical and are
referenced instead of inlined -- a one-line pointer replaces the seam
and body -- while their extraFiles still vendor under parts/<slot>/
and their allowed-tools still join the union, both with the same
parts/<slot> rewrite, and metadata.compiled still carries their
binding@version.

Adds lib/skills/sources.ts: stripJsonc/stripFrontmatter parsing
primitives, resolvePluginRoots (thin, subprocess-backed), and the
loadStepSource/loadAttachment/readVerbRoster/readManifestBindings/
invocableRoster functions that feed Task 1's compile core. Fixture-driven
tests via mkdtemp cover the fs-backed functions; resolvePluginRoots stays
untested per the plan (Task 5 exercises it live).

The two "not found" tests for loadStepSource/loadAttachment previously
asserted only an identifier substring, so they would pass even if the
searched-paths listing were empty or broken. Assert the thrown message
contains the fixture's actual expected search paths (the SKILL.md
candidate under skills/pipeline/, and for loadAttachment both a skills/
candidate and the attachments/ candidate) so a regression that drops the
searched list fails the test.

Wires the compile core (Task 1) and source/manifest IO (Task 2) into
`rt skills compile` and `rt skills check`. --pack-dir/--mattstack-dir
are hidden test-only flags so fixture tests never touch real
~/.mattstack or ~/.claude; --mattstack-dir also stands in for the
Claude plugin cache in tests since execSync-based PATH shims don't
reliably reach a mocked `claude` binary from inside this process.

Review fix round 1:
- commands/skills.ts: wrap skillsCompile/skillsCheck in a SkillsUsageError
boundary matching commands/secrets.ts and commands/settings-keys.ts --
expected domain errors (missing binding, ambiguous/absent manifest,
unknown verb, unrecognized argument) now print a one-line
"rt skills: <message>" to stderr and exit 1 with no stack trace;
anything else still propagates.
- lib/skills/sources.ts: resolvePluginRoots now skips a plugin-list entry
whose installPath no longer exists (real case on dev machines: a stale
cache entry) instead of crashing resolution for every other plugin,
printing a one-line warning naming the plugin and path. Entry-processing
logic split into buildPluginRoots so it's fixture-testable; the
subprocess call itself stays thin and untested, as before.

compileSkill gains opts.internalRoster: a body token or registered fill

skillsCompile skips non-public verbs (removing their compiled dir),

readVerbRoster now rejects stubs.jsonc verb keys containing "/", "\\", or

sites (writeCompiledVerb, the internal-verb skip). Also adds an
end-to-end skillsCompile test where the pack dir and the resolved

against real loadAttachment resolution (inline + misplaced flag) and
routing an internal name-reference through the errors-abort path.

fzf's default --multi accept emits the cursor row on Enter even when
nothing is marked, so unchecking everything could silently reintroduce
one skill into public. Compute the public/internal delta before writing
anything, print it, and require an explicit y/N confirm when it's
non-empty; "no changes" short-circuits without prompting. The decision
itself (decidePaletteAction) is a pure function so the gate is unit-
tested without spawning fzf or reading a terminal.
Also corrects lib/fzf.ts's module doc, which claimed every fzf spawn
site calls ensureFzf() -- the surface palette's non-tty/missing-fzf
fallback is a deliberate exception.

readSurface now falls back to <packDir>/surface.jsonc for packs without a

non-SKILL.md step file (references/, scripts/, ...) and the compiler vendors

… exclude junk from vendoring
Review fixes on the surface-ratchet wave: (1) compileSkill lints the verb
description against the internal roster, and non-public stub verbs seed
that roster even when their compiled dirs are already deleted -- dangling
references to retired doors now fail the compile; (2) vendoring skips
dotfiles/dotdirs, __pycache__/, *.pyc, tests/ dirs, *.test.sh, and
README.md so development junk stays out of compiled artifacts.

computeInternalRoster only scanned skills/ and non-public stub verbs, so a
name that migrated to attachments/ via `surface apply` dropped out of the
roster -- a body/description token still naming it downgraded from a
compile error to a mere "not invocable" warning. Scan attachments/ too.
Also: resolvePluginRoots' doc comment stated its constraint via process
artifacts ("plan constraint", "Task 5") instead of the constraint itself;
and the skills node description in the command tree omitted surface.

Non-public mattstack engines are moving from skills/<group>/<engine> to
attachments/<group>/<engine> (unregistered, so they drop out of the
user's slash autocomplete while staying invocable by name). Search the
same shape loadAttachment uses -- flat attachments/<engine>/SKILL.md
then one group level deep -- and report every path tried on a miss.
invocableRoster already only walks skills/, so it excludes attachments
by construction; added a roster assertion to make that explicit.

- skills-surface.test.ts: stub process.stdin.isTTY false in the non-tty
palette test so it never spawns real fzf on an interactive run.
- skills.test.ts, skills-surface.test.ts: afterEach assigns
process.exitCode = 0, not undefined -- Bun ignores undefined once the
code is truthy, so undefined could leak a nonzero exit into the suite.
- skills.ts skillsCheck: compare the emitted path set against the actual
outDir contents (extra files report as stale orphans) and treat a
missing outDir for a public verb as stale instead of skipping it.
- skills.ts computeRows/runPalette: include surface.public names absent
from skills/, attachments/, and stubs.jsonc as rows (kind "missing")
so the palette's delta preview and write no longer silently drop them.

The team match uses a loose substring test.

header.includes(team) matches any occurrence in the leading comment block. A short team name such as t matches unrelated text, for example the word mattstack or another team's name that contains it. The command then selects the newest matching manifest without warning, because the ambiguity guard triggers only on an mtime tie.

Consider matching the documented provenance token instead, for example a word-boundary or <team>@<team> pattern.

skillsCheck reports a non-public verb with a leftover outDir as current.

skillsCompile deletes outDir for a verb that is absent from surface.public (lines 310-312) and prints misplaced with exit code 1 for any non-public directory under skills/ (lines 332-338). skillsCheck does neither. For a non-public verb whose directory still exists, line 364 compiles the verb and compares files, so the command can print current and exit 0 while a real compile would remove the directory.

Report a non-public verb that still has an outDir as stale, and mirror the misplaced-directory scan.

writeSurfaceConfig can create a second surface config file.

readSurface accepts <packDir>/pack/surface.jsonc or <packDir>/surface.jsonc, and prefers the pack/ copy (lib/skills/sources.ts:324-335). writeSurfaceConfig always writes the pack/ copy. For a pack that declares its surface at the plugin root, set and the palette leave the root file in place and shadow it. The repository then carries two files, and the root file drifts silently.

Write back to the file that readSurface resolved, or delete the shadowed root file after the write.

git mv fails on an untracked directory and aborts with a raw error.

isInsideGitWorkTree returns true for any pack directory inside a work tree, including a directory that git does not track. git mv then exits non-zero with fatal: not under version control, and execFileSync throws. The error is not a SkillsUsageError, so it reaches the top-level crash handler with a stack trace. runSet already wrote surface.jsonc at that point, so the config and the directory layout disagree.

Fall back to renameSync when git mv fails.

The palette resolves fzfPath but spawns the bare name fzf.

Line 680 gates the interactive path on resolveFzf(). Line 700 then spawns "fzf", which relies on PATH lookup. If resolveFzf() returns a location that PATH does not cover, spawnSync fails with ENOENT, result.status is null, and line 717 reports cancelled -- no changes made. The user gets a silent no-op with no diagnostic.

In `@commands/skills.ts` around lines 680 - 720, Use the resolved fzfPath when
invoking spawnSync instead of the bare "fzf" command, and distinguish spawn
failures (such as a null status or execution error) from a normal user
cancellation in the result handling. Preserve the existing cancellation message
only for an actual user cancel, and report a diagnostic when fzf cannot be
started.

R-T7-a (#1): tool.daemon's launchd/worktrees sub-facts are real negative
signals now, not folded into a "ready" detail — either failing flips the
row to "invalid" with the specific fact named.
R-T7-b (#4): the legacy split-state branch (required, invalid) carries a
{type:"steps"} merge-by-hand remedy instead of action:null; the detail also
gets verify's plural handling back.
R-T7-c (#6): fixes the bundle-memo hazard at its source. appBundleRoot()
(lib/bundle-layout.ts) now memoizes only the true default
(exists === existsSync); an injected exists (every Probes-driven caller)
never reads or writes it. Validator tests drop the reset ceremony this made
unnecessary.
R-T7-d (#12): tool.rt-link's needs-you branch carries a {type:"run"} action
to fix the link in one step.
#2/#3: tool.fzf and tool.rt now distinguish "genuinely absent" (127) from
"resolved but won't run" (any other exit) — the latter is "error", never
"ready"/"missing".
#5: tool.daemon and tool.app get recheck:"on-activate" (Task 6's convention
for out-of-band, leave-the-app-and-come-back rows).
#7: the five optional rows carry real optionalNotes.
#8: tool.app's legacy note names the exact hit path(s), matching verify's
phrasing.
#9: interceptsRow wraps shimReport()/staleIntercepts() so a throw degrades
to an "error" row instead of rejecting the whole plan.
#10: tool.daemon's Login Items action is imported from permissions.ts
(now exported as LOGIN_ITEMS_SETTINGS_ACTION) instead of a duplicate
literal.
#11: lib/shell-integration.ts gains detectShellFrom()/shellRcPathFor(),
pure functions the real detectShell()/shellRcPath() now delegate to and
tool.shell reuses over Probes; an unrecognized shell gets an honest
"can't write automatically" detail instead of "Install writes it".
#13: the tool.daemon describe saves/restores DAEMON_CONFIG_PATH's
pre-existing content around the whole block instead of only deleting it,
so status-fallback.test.ts's absence assumption can't be poisoned.
#14/#15: header comment no longer cites the brief's table, the rt-link
"no app" test asserts its reason string, and commands/verify.ts's docblock
is trimmed to the one load-bearing line.
