Antigravity CLI Plugin Commands

Validate and install from the generated local plugin package:

agy plugin validate /path/to/endor-labs-agent-kit/plugins/antigravity/endor-labs-agent-kit
agy plugin install /path/to/endor-labs-agent-kit/plugins/antigravity/endor-labs-agent-kit
agy plugin list

Remove the plugin only after explicit user approval:

agy plugin uninstall endor-labs-agent-kit

Antigravity CLI is the consumer migration path for Gemini CLI. Keep Gemini extension installation and Antigravity plugin installation as separate host-specific choices, and validate the selected package before installing.

Endor Agent Kit Setup

Use this setup workflow when the user asks to install, check, update, or remove Endor Labs Agent Kit plugin support files, or when an Endor Agent Kit workflow is blocked by missing endorctl, GitHub CLI, authentication, namespace, or local toolchain readiness.

Setup Contract

Be proactive about checking the environment, but do not make persistent changes without explicit user approval. Report evidence for each check. Never print secret values.

Setup may:

• Inspect command availability and versions for endorctl, gh, git, and workflow-relevant language tooling.
• Read ENDOR_NAMESPACE from the current process environment and report it as namespace provenance when present.
• Safely parse ~/.endorctl/config.yaml for non-secret fields such as ENDOR_API and ENDOR_NAMESPACE.
• Report the presence of credential fields by key name only.
• Report the presence of ENDOR_API_CREDENTIALS_* authentication variables by key name only.
• Run lightweight read-only Endor auth verification when config or credentials are present.
• Offer re-authentication when verification fails.
• Check gh authentication and point to official installation guidance.
• Inspect Endor MCP support when a selected workflow needs MCP or the user asks for MCP setup.
• Offer host-specific Endor MCP configuration only after explaining the exact file, command, and validation step.
• Install, update, or uninstall host-specific Agent Kit support files only after explicit approval.

Setup must not:

• Run endorctl scan.
• Run endorctl host-check.
• Print ~/.endorctl/config.yaml or secret values.
• Read, cat, source, recurse through, or point ENDORCTL_CONFIG or --config-path at tenant-specific, customer-specific, production, backup, or other non-default Endor config directories.
• Ask the user to paste API keys, API secrets, tokens, or passwords into chat.
• Write ENDOR_API_CREDENTIALS_KEY or ENDOR_API_CREDENTIALS_SECRET.
• Edit shell profile files such as .zshrc, .bashrc, or PowerShell profile.
• Install gh, package managers, language runtimes, Docker, JDKs, or build tooling.
• Configure MCP globally without explicit user approval. MCP remains opt-in per recipe/workflow.

Readiness Report

Start with a concise readiness report. Separate configured state from verified state.

Include these sections when relevant:

• Ready
• Needs action
• Optional checks
• Available fixes

For Endor auth, report sanitized fields only:

Endor config: found
API endpoint: https://api.endorlabs.com
Namespace candidates:
- ENDOR_NAMESPACE: not set
- ~/.endorctl/config.yaml ENDOR_NAMESPACE: example-namespace
Selected namespace: example-namespace from ~/.endorctl/config.yaml
Auth: API credential fields present
Endor auth: verified for namespace example-namespace
Secret values: hidden

If a namespace is missing, say that a namespace is required before live Endor lookups. If a namespace is detected, let the user use it or override it for the current workflow.

If ENDOR_NAMESPACE from the current process environment and ~/.endorctl/config.yaml disagree, surface both values and stop before live Endor lookups. Ask the user which namespace to use for this workflow. Do not silently trust either value, and do not unset environment variables or edit config files unless the user explicitly asks for that separate operational cleanup.

When the user selects or supplies a namespace, later workflow agents must pass it explicitly with -n <namespace> or --namespace <namespace> for scoped Endor lookups rather than relying on bare endorctl namespace resolution.

Endor Tooling

If endorctl is missing, offer documented install options in this order:

1. Package manager route when available, such as Homebrew or npm.
2. Direct binary download with checksum verification.

Only install endorctl after explicit approval. If installing to ~/bin, tell the user how to update PATH for the current shell. Do not edit shell profiles.

If API credential fields are present, do not run browser auth unless the user explicitly asks to switch or re-authenticate. If API credential setup is needed, tell the user to set ENDOR_API_CREDENTIALS_KEY and ENDOR_API_CREDENTIALS_SECRET through their preferred secure environment mechanism.

When browser or SSO authentication is requested, confirm the namespace first. Use non-interactive flags where supported. If multi-tenant selection appears, summarize the available tenant choices and ask the user before retrying.

Endor MCP

Require endorctl agent api --help to succeed for workflows that use Endor CLI API calls. Each selected workflow must pass its canonical recipe id through --agent-id; never fall back to the unattributed legacy API command. Configure Endor MCP only when a selected MCP-capable workflow needs it or the user explicitly asks for it.

The distribution may include ready-to-use Endor MCP config snippets such as root .mcp.json or Gemini mcpServers metadata. Treat those files as setup inputs, not permission to start or register MCP without approval.

When MCP setup is requested:

1. Check whether npx is available.
2. Check whether endorctl is available.
3. Verify the proposed server command is: npx -y endorctl ai-tools mcp-server.
4. Inspect the host-specific MCP config location or installed plugin metadata.
5. If endor-cli-tools is already registered, report it and ask before changing anything.
6. If it is missing, show the exact config that would be added and ask for approval before writing host config files.
7. After approval and configuration, validate in a fresh host session when the host supports tool visibility checks.

Do not claim Endor MCP tools are available to a workflow until the host exposes them in the current session. If MCP tools are unavailable, continue with CLI-first workflows when they support endorctl agent api --agent-id <canonical-recipe-id>; otherwise record the missing MCP capability in data_gaps.

GitHub CLI

Check gh auth status when workflows need GitHub evidence, repository inventory, pull requests, or comments. If gh is missing, provide current official installation guidance instead of installing it automatically.

Do not manage GitHub token scopes or create personal access tokens. Verify only the specific read or write capability needed for the selected workflow.

Language Tooling

Detect and report workflow-relevant package managers, language runtimes, and build tools. Do not install them.

When tooling is missing, report the affected validation step and ask the user to install it through their team-standard toolchain.

Workflow Safety

Setup never performs remediation, creates branches, opens PRs/MRs, posts comments, writes Endor policies, or runs scans. Mutating workflows such as SCA Remediation and AI SAST Remediation keep those actions behind their generated agent approval gates.

Antigravity-Specific Rules

• Keep Antigravity plugin installs explicit. Do not install, link, update, enable, disable, or uninstall plugins without user approval.
• Do not add plugin-wide MCP automatically. Only guide MCP setup when a selected workflow needs it and the user approves.
• Do not collect, write, or persist Endor API credential values. Report credential presence by key name only.
• Invoke bundled subagents as @agent-name when delegating a workflow; do not invent alternate invocation names.
• Do not narrate tool-planning chatter. Return the requested evidence, decisions, and gaps.
• When required Endor evidence is unavailable, include evidence_queries and non-empty data_gaps instead of guessing.
• Antigravity subagents are host-managed; if subagent delegation is unavailable, use the matching skill and report the limitation.
• Tell the user to restart Antigravity CLI after installing or updating the plugin if newly installed skills or subagents are not visible.
