maintain-cross-platformMaintainer guide to where AgentSys keeps its marketplace, installer, transforms and adapters, and what to run when preparing a release or fixing a platform bug.
AgentSys installs the agent-sh plugins on Claude Code, OpenCode, Codex CLI, Cursor and Kiro, and this maintainer skill, for that repository only, works as a map. A table says where each concern lives: the marketplace file and its pinning script, the installer in `bin/cli.js` with one function per tool, transforms in `lib/adapter-transforms.js` (synced from agent-core, so changes belong there), platform adapters, dev installs, version bumps and generated documentation sections.
It also lists the differences behind most cross-platform bugs: the plugin root variable differs between Claude Code and the other hosts, Windows backslashes in `require()` paths must be normalized, and the state directory should come from `AI_STATE_DIR` instead of a hardcoded `.claude/`. For current facts it points to the compatibility checklist, `docs/CROSS_PLATFORM.md` and the release checklists rather than memory.
Read from SKILL.md and the folder at commit 68eb4a7. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
npmnodenpxFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
AgentSys Cross-Platform Maintenance loads about 1.2k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 489 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/maintain-cross-platform/SKILL.md (or your agent's skills folder).AgentSys installs the agent-sh plugins on Claude Code, OpenCode, Codex CLI, Cursor and Kiro. The plugins live in their own repos; this repo owns the marketplace, the installer, the transforms and the docs. Use this skill to find where a cross-platform concern lives and what to run.
Platform details (config formats, frontmatter, env vars, label limits) are in checklists/cross-platform-compatibility.md and docs/CROSS_PLATFORM.md; release steps are in checklists/release.md and agent-docs/release.md. Read them for the current facts instead of relying on memory.
| Concern | Location |
|---|---|
| Marketplace, one entry per plugin pinned by tag and commit | .claude-plugin/marketplace.json; re-pin with node scripts/pin-marketplace.js [--dry-run] (needs gh) |
| Installer | bin/cli.js: installForClaude, installForOpenCode, installForCodex, installForCursor, installForKiro. Claude Code installs from the marketplace; the others fetch plugin sources into ~/.agentsys/plugins/<name> and transform them. |
| Transforms (frontmatter, tools to permissions, plugin-root paths, namespaces) | lib/adapter-transforms.js. lib/ is synced from agent-sh/agent-core, so make the change there; an edit here is overwritten by the next sync. |
| Platform adapters | adapters/opencode-plugin/ (native OpenCode plugin), adapters/opencode/, adapters/codex/; scripts/gen-adapters.js keeps generated files fresh |
| Dev installs | node bin/dev-cli.js dev-install [tool] (scripts/dev-install.js) |
| Versions | package.json is the source; npx agentsys-dev bump X.Y.Z stamps package-lock.json, .claude-plugin/plugin.json, marketplace.json and site/content.json. Plugin repos version independently. |
| Generated doc sections | <!-- GEN:START:... --> blocks, rewritten by npx agentsys-dev gen-docs |
${CLAUDE_PLUGIN_ROOT} in Claude Code, ${PLUGIN_ROOT} in OpenCode and Codex; Cursor and Kiro get the install path inlined. Normalize backslashes in require() paths (.replace(/\\/g, '/')), because a Windows path such as C:\Users\... turns into escape sequences.AI_STATE_DIR (.opencode, .codex, .cursor, .kiro; unset means .claude) instead of a hardcoded .claude/. validate paths catches hardcoded ones.--no-strip keeps them), tools become permission: entries, and AskUserQuestion labels longer than 30 characters fail.$name, so every skill description needs trigger phrases ("Use when ...").~/.kiro/prompts/, agents become JSON in ~/.kiro/agents/, and two combined reviewer agents fit its 4-subagent limit. Each skill directory is copied whole to ~/.kiro/skills/<name>/, away from its plugin, so the installer and the Kiro transforms point plugin-root wording ("two directories up from this skill"), relative links that leave the skill directory, and versioned-cache globs (**/<plugin>/*/) at ~/.agentsys/plugins/<plugin>.| Command | Covers |
|---|---|
npm run validate | plugins, cross-platform, consistency, paths, counts, platform-docs, agent-skill-compliance |
npm test | Jest suite |
npm run gen-docs:check, node scripts/expand-templates.js --check, node scripts/gen-adapters.js --check | Generated content is fresh (CI runs all three) |
npx agentsys-dev preflight [--all|--release] | Change-aware checklist checks. The pre-push hook runs it, asks for the /enhance confirmation, and runs --release when a v* tag is pushed. |
node bin/dev-cli.js validate opencode-install | A real OpenCode install (not part of validate) |
npm pack --dry-run | The package builds |
Before a release, smoke-test the installer: npm pack, npm install -g ./agentsys-*.tgz, run agentsys, and check each platform's install directory as checklists/release.md lists.
If this skill or a checklist no longer matches the code, fix it in the same change.

Maintainer guide to where AgentSys keeps its marketplace, installer, transforms and adapters, and what to run when preparing a release or fixing a platform bug. AgentSys installs the agent-sh plugins on Claude Code, OpenCode, Codex CLI, Cursor and Kiro, and this maintainer skill, for that repository only, works as a map.js` (synced from agent-core, so changes belong there), platform adapters, dev installs, version bumps and generated documentation sections.
AgentSys Cross-Platform Maintenance fits situations like: preparing an AgentSys release; checking cross-platform compatibility of the installer or adapters; changing marketplace pins, transforms or adapter generation.
Run `npx skills add agent-sh/agentsys --skill maintain-cross-platform -a claude-code`. Or copy the skill folder (meta/skills/maintain-cross-platform in agent-sh/agentsys) into .claude/skills/maintain-cross-platform in your project. Claude Code loads it when a task matches its description.
Run `npx skills add agent-sh/agentsys --skill maintain-cross-platform -a codex`. Or copy the skill folder (meta/skills/maintain-cross-platform in agent-sh/agentsys) into .agents/skills/maintain-cross-platform in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add agent-sh/agentsys --skill maintain-cross-platform -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/maintain-cross-platform, .gemini/skills/maintain-cross-platform, .github/skills/maintain-cross-platform and .opencode/skills/maintain-cross-platform in your project.
Going by SKILL.md and its folder, AgentSys Cross-Platform Maintenance needs the command-line tools its instructions call (npm, node and npx). Our summary lists: A checkout of the AgentSys repository; GitHub CLI `gh` and Node.js, for the marketplace pinning script.
SKILL.md contains no URLs. Its commands use npm and npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
AgentSys Cross-Platform Maintenance is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
