Skills CLI Sync

Skills CLI sync (AGENT_DEFINITIONS)

This app mirrors the agent list of the upstream vercel-labs/skills CLI. When upstream ships a release, AGENT_DEFINITIONS, UNIVERSAL_AGENT_IDS, and SKILLS_CLI_VERSION in src/shared/constants.ts must be re-synced, the docs refreshed, and the gates re-run. This skill encodes that procedure.

The steps below are invariant — they hold for any version bump. Concrete counts and agent names belong only to the "Latest run" section at the bottom; never bake a count into a step.

Source of truth

• Upstream: src/agents.ts (agent list) and src/types.ts (the Agent shape + home-dir helpers) in vercel-labs/skills.
• This app: the JSDoc on AGENT_DEFINITIONS, UNIVERSAL_AGENT_IDS, and SKILLS_CLI_VERSION in src/shared/constants.ts is authoritative — read it before editing. CLAUDE.md → Domain Concepts → Skills CLI lists the same pointers. Don't duplicate those rules here; this skill is the procedure.

Phase 1 — Fetch the upstream agent list (no local clone)

Tags are v-prefixed (v1.5.10; bare 1.5.10 404s). Fetch the two source files at the version you're syncing to — reproducible on any machine:

NEW=1.5.11   # the upstream version you are syncing to
BASE="https://raw.githubusercontent.com/vercel-labs/skills/v${NEW}"
curl -fsSL "$BASE/src/agents.ts" -o /tmp/agents.ts
curl -fsSL "$BASE/src/types.ts"  -o /tmp/types.ts

Use …/main/… instead of v${NEW} to preview the latest unreleased list.

Phase 2 — Extraction rules (getting these wrong breaks the sync silently)

• Join on the upstream name: field — it equals the --agent flag value and this app's cliId. Not displayName. Display names can match while ids diverge (the kimi trap).
• name: keys can be quoted / hyphenated ('kimi-code-cli', 'kiro-cli'). A naive ^\s+\w+: { regex misses them — extract with grep "name: '".
• globalSkillsDir / skillsDir are usually computed from home-dir helper constants at the top of agents.ts (e.g. configHome=~/.config, codexHome=~/.codex, claudeHome=~/.claude, plus per-vendor homes). Resolve each to a concrete ~/…-relative path before deriving anything.

grep -nE "name: '" /tmp/agents.ts   # the upstream agent identifiers (= cliId)

For each upstream agent read: name, displayName, globalSkillsDir, skillsDir, showInUniversalList. Then diff the upstream name: set against the current cliId set in AGENT_DEFINITIONS to find additions, removals, and cliId renames.

Phase 3 — The two INDEPENDENT derivation rules (do not conflate)

Rule A — installDir / scanDir (from globalSkillsDir):

• installDir = the parent of globalSkillsDir, home-relative.
• scanDir = installDir, except when globalSkillsDir resolves to the universal source ~/.agents/skills → scanDir diverges to .<name>. This is the v0.13.0 guard: if scanDir aliased the source, the scanner would surface every shared source skill as that agent's own "valid local skill".

Rule B — UNIVERSAL_AGENT_IDS (from skillsDir):

• An id belongs iff skillsDir === '.agents/skills' && showInUniversalList !== false.
• Note it keys off skillsDir, not globalSkillsDir. An agent can be universal (reads ~/.agents/skills) yet keep its own globalSkillsDir (so no scanDir override) — that's the canonical proof the two rules are independent. Don't assume "universal ⇒ scanDir diverges" or vice-versa.

Phase 4 — Exclusions

Skip an upstream agent when:

• globalSkillsDir: undefined — it can't be represented as an install path.
• It's a showInUniversalList: false pseudo-agent (a non-real aggregate entry).
• Its globalSkillsDir collides with another agent's dir → a scanDir clash that would double-count the shared directory.

showInUniversalList: false also excludes an otherwise-eligible agent from UNIVERSAL_AGENT_IDS.

Phase 5 — Edit src/shared/constants.ts

• Add / modify AGENT_DEFINITIONS entries (id, cliId, name, installDir, scanDir). Every field is required — no silent fallback.
• Keep the internal id stable when only cliId changes. id is the Redux/checkbox state key; changing it drops persisted user state. (kimi kept id: 'kimi-cli' while cliId became kimi-code-cli.)
• Display-name-only rebrand: change name only; leave id / cliId / installDir / scanDir. Then grep the renderer for the old display name and update any UI example/doc that hard-codes it (e.g. a StatusBadge JSDoc @example).
• Update UNIVERSAL_AGENT_IDS per Phase 3 Rule B.
• Bump SKILLS_CLI_VERSION.
• Do not hand-edit derived values. AgentId / AGENT_IDS (z.enum) / AgentName / AGENT_ID_TO_CLI_NAME / SHARED_AGENT_PATHS all derive from AGENT_DEFINITIONS automatically.
• The app's only CLI surface is find + add (skillsCliService). New upstream commands (run / prompt / sync / …) need no app change.

Phase 6 — Update the docs

• CLAUDE.md — SKILLS_CLI_VERSION in the Domain Concepts → Skills CLI table.
• README.md — the "N AI Agents Supported" count, any renamed display name, and the "…and X more" tail.
• SPEC.md — the agent table (add new rows, fix renames), every agent-count mention, then reflow: npx prettier --write SPEC.md (a wider new cliId can re-pad the whole table — that diff is expected, not churn).

Phase 7 — Validate (all must pass, in order)

node .claude/skills/skills-cli-sync/reconcile-agents.mjs   # constants ↔ SPEC drift gate
npx prettier --check README.md SPEC.md CLAUDE.md
pnpm validate                                              # lint + test + typecheck + dead-code
pnpm test:e2e                                              # only after validate is green

reconcile-agents.mjs (shipped beside this file) asserts every AGENT_DEFINITIONS entry has a matching SPEC row on (cliId, detection-path) and that no SPEC row references a removed cliId. It exits non-zero on drift, so it doubles as a CI / pre-PR gate.

Also confirm no stale references survive:

git grep -nE "<OLD_VERSION>" -- '*.md' '*.ts'   # e.g. 1\.5\.9 — should be only intentional history
git grep -n "<old display name>" -- '*.ts' '*.tsx'

Phase 8 — Commit

One focused commit, e.g. chore: sync skills CLI agent definitions to <NEW>. Summarize in the body: agents added/removed, any id/cliId migrations, display-name rebrands, the UNIVERSAL_AGENT_IDS delta, and the version bump. Do not bump package.json version — releases are owned solely by /electron-release.

Latest run (example — point-in-time, NOT part of the procedure)

2026-08-26 JST · v1.5.18 → v1.5.23 (+4 community agents)

• +4 agents: grok (Grok Build) and kimchi (Kimchi) from v1.5.20, minimax-code (MiniMax Code) from v1.5.22, and posit-assistant (Posit Assistant) from v1.5.23. Each keeps its own global skills directory, so installDir = scanDir; AGENT_DEFINITIONS 69 → 73.
• No migrations/rebrands: zero app orphans; no id/cliId, path, or display-name changes to existing agents. UNIVERSAL_AGENT_IDS stays 16 because all four additions use their own skillsDir.
• Excluded at this version: eve and promptscript (globalSkillsDir: undefined), universal (showInUniversalList: false), zenflow (dir collides with zencoder's ~/.zencoder/skills).
• Edits: bumped SKILLS_CLI_VERSION 1.5.18 → 1.5.23; updated the e2e pin, CLAUDE.md pinned-version cell, README/SPEC agent counts and table, website metadata/copy, llms.txt, and the website's download links to the current v0.27.3 release assets.
• Gates: reconcile-agents.mjs clean (73/73), prettier clean, pnpm validate green (180 files / 2313 tests), pnpm test:e2e green (61 tests), website lint/build green.

2026-07-16 · v1.5.13 → v1.5.18 (+1 community agent)

• +1 agent: zcode (ZCode, added upstream in v1.5.16) — own home dir ~/.zcode/skills, so installDir = scanDir = '.zcode' (no universal-source divergence). AGENT_DEFINITIONS 68 → 69; UNIVERSAL_AGENT_IDS stays 16 (zcode's skillsDir is .zcode/skills, not .agents/skills).
• No migrations/rebrands: zero app orphans; no id/cliId or display-name changes. Upstream types.ts only widened its own AgentName union.
• Excluded at this version: eve and promptscript (globalSkillsDir: undefined), universal (showInUniversalList: false), zenflow (dir collides with zencoder's ~/.zencoder/skills).
• Edits: bumped SKILLS_CLI_VERSION 1.5.13 → 1.5.18; bumped the e2e pin (marketplace-install-regression.e2e.ts literal skills@1.5.18 add … + comment); bumped the CLAUDE.md Domain-Concepts pinned-version cell; agent count 68 → 69 in README/SPEC + website copy (Hero, Features, layout, llms.txt — llms.txt was still at a stale 54).
• Gates: reconcile-agents.mjs clean (69/69), prettier clean, pnpm validate green, pnpm test:e2e green.

2026-06-24 · v1.5.11 → v1.5.13 (version pin + excluded upstream agent)

• No app agent-list change: upstream name: set is 72 and app cliId set stays 68. The only upstream addition since v1.5.11 that is not already mirrored is eve, which has globalSkillsDir: undefined, so Phase 4 excludes it. App orphans remained zero.
• Unchanged derived sets: AGENT_DEFINITIONS stayed 68, UNIVERSAL_AGENT_IDS stayed 16, with no id/cliId migrations and no display-name rebrands.
• Excluded at this version: eve and promptscript (globalSkillsDir: undefined), universal (showInUniversalList: false), zenflow (dir collides with zencoder's ~/.zencoder/skills).
• Edits: bumped SKILLS_CLI_VERSION 1.5.11 → 1.5.13; bumped the e2e pin (marketplace-install-regression.e2e.ts literal skills@1.5.13 add … + comment); bumped the CLAUDE.md/AGENTS.md Domain-Concepts pinned-version cell; ignored local .agents/** in ESLint so repo-local skill copies do not break pnpm validate.
• Gates: reconcile-agents.mjs clean, prettier clean, pnpm validate green, pnpm test:e2e green (60 tests).

2026-06-14 · v1.5.10 → v1.5.11 (version-only bump)

• No agent-list change: src/agents.ts is byte-identical between v1.5.10 and v1.5.11 (diff clean), so AGENT_DEFINITIONS, UNIVERSAL_AGENT_IDS, and every doc agent-count stayed put. Drift gate confirmed: upstream name: set (71) minus app cliId set (68) = exactly the 3 standing exclusions below; zero app orphans.
• Edits: bumped SKILLS_CLI_VERSION 1.5.10 → 1.5.11; bumped the e2e pin (marketplace-install-regression.e2e.ts literal skills@1.5.11 add … + comment); bumped the CLAUDE.md Domain-Concepts pinned-version cell.
• Unchanged history kept verbatim: the "CLI 1.5.10" / "added in v1.5.10" comments in constants.ts and the *.test.ts files are accurate history of when kimi migrated / agents landed — not bumped.
• Excluded at this version (still valid, agents.ts unchanged): promptscript (globalSkillsDir: undefined), universal (showInUniversalList: false), zenflow (dir collides with zencoder's ~/.zencoder/skills).
• Gates: reconcile-agents.mjs clean, prettier clean, pnpm validate + pnpm test:e2e green.

2026-06-05 · v1.5.5 → v1.5.10 (PR #204, commit 41b455e)

• +14 community agents: antigravity-cli, astrbot, autohand-code, inference.sh, jazz, lingma, loaf, moxby, ona, qoder-cn, reasonix, terramind, tinycloud, zed.
• kimi migration: cliId kimi-cli → kimi-code-cli; installDir .config/agents → .agents; scanDir → .kimi. Internal id kept kimi-cli (state preservation).
• Windsurf → Devin Desktop: display name only; the .codeium/windsurf install/scan path is unchanged (upstream CLI was not renamed).
• Counts: AGENT_DEFINITIONS 54 → 68; UNIVERSAL_AGENT_IDS 13 → 16 (+antigravity-cli, loaf, zed).
• scanDir-divergent at this version (Rule A exceptions): cline, dexto, kimi-code-cli, loaf, warp, zed.
• Excluded at this version: promptscript (globalSkillsDir: undefined), universal (showInUniversalList: false), zenflow (dir collides with zencoder's ~/.zencoder/skills).
• Gates: pnpm validate (1376 tests) + pnpm test:e2e (55 tests) green.
