How well agents can access and operate the product
Agent access
ai-native userPoint an agent at llms.txt or agent-oriented docs
weight 2 · round to OpenCodeGemini CLInone0/10No evidence Gemini CLI has any documented feature for consuming llms.txt or agent-oriented doc manifests; the only related probe shows llms.txt returning 404 on Google's own docs site, and none of the GitHub feature list or docs mention llms.txt support. GEMINI.md context files are a different, project-local mechanism, not agent-oriented web docs discovery.
OpenCode's own llms.txt file returns 404, so there is no dedicated llms.txt for agents, but probes show that docs pages are available in machine-readable Markdown form (.md suffix returns 200), which serves an analogous agent-oriented documentation function. There's no first-party statement about llms.txt support or explicit agent-doc pointing workflow. Missing for 10: an actual llms.txt endpoint, documentation instructing users to point agents at machine-readable docs, and confirmation that agents can consume the .md docs as intended.

ai-native userIssue scoped/least-privilege API credentials for an agent
weight 2 · round to OpenCodeGemini CLInone0/10Evidence shows Gemini CLI abstracts away API key management entirely (sign in with Google account) rather than offering scoped or least-privilege credential issuance for agents; no docs mention credential scoping, permission boundaries, or token minting for agent use.

OpenCode's permission config lets you restrict which actions (edit, bash, etc.) an agent may auto-run, prompt for, or block, and enterprise SSO integration centralizes access to an internal AI gateway — both are adjacent to least-privilege agent control, but neither is a mechanism for issuing scoped API credentials/keys specifically to an agent. missing for 10: explicit scoped API-key/credential issuance for agents, credential expiry/rotation, per-agent key scoping documentation, independent verification of this capability.

OpenCode has a GitHub Actions integration (mention /opencode or /oc in a comment) and a read-only 'plan' agent that can review/suggest changes without modifying code, which can be used for PR feedback, but this requires an explicit manual mention rather than automatically triggering contextual review on every PR.

OpenCode offers a read-only 'plan' agent for reviewing suggested changes without applying them and a permission system that can prompt before actions run, plus GitHub PR/Actions integration for submitting changes — these provide some review-safety scaffolding.

Safe execution

weight 2 · round to OpenCodeGemini CLI supports configuring MCP servers via ~/.gemini/settings.json and exposes /tools and /mcp commands to inspect and manage available tools, giving engineering leads some control over which integrations are enabled. However, evidence lacks any centralized admin/policy control, allowlist/denylist enforcement, or org-wide governance mechanism for restricting tool access across a team, and community reports note weak security defaults (e.g. opening root directories without prompting). missing for 10: org-level/admin enforcement of tool allowlists, granular permission scoping per tool/integration, independent verification that access controls are robust rather than just configurable per-user.

OpenCode's permission system lets leads set actions to auto-run, prompt, or block per tool/input, and MCP servers (external tools) are explicitly added/configured (docs-4/23/41). Enterprise config also lets orgs force use of an internal AI gateway and SSO, further restricting what integrations agents can reach (docs-33/50).

Not comparable on these axes

weight 3 · not comparableGemini CLIn/aGemini CLI is itself an agent/coding assistant; the evidence only shows it acting as an MCP client (configuring and connecting to external MCP servers per gh-5, gh-19), which is explicitly the client-side role and does not make the 'serve as an official MCP server' axis applicable. No evidence exists of Gemini CLI itself running as an MCP server.
OpenCoden/aOpenCode is itself a coding agent (client role), and the evidence only shows it consuming external MCP servers as tools (opencode-docs-4, opencode-docs-23) plus a separate headless OpenAPI/HTTP server (opencode-docs-30, opencode-docs-45) — not an official MCP server mode for OpenCode itself.
