dotagents

Shared tooling for coding agents. Declare skills, MCP servers, hooks, subagents, and plugins in agents.toml — dotagents wires them into every agent tool on your team.

Why dotagents?

One source of truth. Skills live in .agents/skills/ and symlink into .claude/skills/ or wherever your tools expect them. Cursor shares Claude-compatible skills. No copy-pasting between directories.

One command to install. Global dependencies live under ~/.agents/. Repository-local dependencies can be declared in a committed agents.toml; collaborators run dotagents --project install to fetch or refresh that project's managed state.

Shareable. Skills are directories with a SKILL.md. Host them in any git repo, discover them automatically, install with one command.

Multi-agent. Configure Claude, Cursor, Codex, GitHub Copilot CLI, Grok, VS Code, OpenCode, and Pi from a single agents.toml -- skills, MCP servers, hooks, subagents, and plugins where supported. Pi reads .agents/skills/ directly.

Quick Start: Global by Default

npx @sentry/dotagents init

Without a scope flag, every command operates on global state under ~/.agents/, even when run inside a repository. The interactive setup walks you through selecting agents and trust policy. Then add skills or plugins:

# Add a skill from a GitHub repo
npx @sentry/dotagents add getsentry/skills find-bugs

# Add multiple skills at once
npx @sentry/dotagents add getsentry/skills find-bugs code-review commit

# Or add all skills from a repo
npx @sentry/dotagents add getsentry/skills --all

# Add a plugin (auto-detected from the source)
npx @sentry/dotagents add getsentry/agent-plugins review-tools

This creates ~/.agents/agents.toml and ~/.agents/agents.lock, making the dependencies available across projects.

Run install again whenever you want to refresh global managed state:

npx @sentry/dotagents install

Repository-Local Workflow

Use --project for repository-local state. Inside Git, dotagents uses the repository root; outside Git, --project init uses the current directory.

# Initialize this repository
npx @sentry/dotagents --project init

# Add a dependency only for this repository
npx @sentry/dotagents --project add getsentry/skills find-bugs

# After cloning or pulling a repository with agents.toml
npx @sentry/dotagents --project install

# Check and repair repository-local state
npx @sentry/dotagents --project doctor --fix

Project commands other than init require agents.toml and never fall back to global state. Existing project and global files are not copied, merged, or removed when switching scopes.
Project-managed paths must also resolve inside the repository: traversal paths and symlinks that point outside it are rejected, while aliases to another location inside the repository remain supported.

Commands

All commands default to global scope (~/.agents/). --global selects it explicitly, and legacy --user remains a compatibility alias. --project selects repository-local state. Combining --project with either global alias is an error.

Source Formats

Skills can come from GitHub, GitLab, any git server, well-known HTTPS skill sources, or local directories. Git and local sources are checked for plugins first. If any plugin is found, add treats the entire source as plugin-only; standalone and bundled skills in that source are not offered. Malformed plugin-shaped content is an error rather than a fallback to skills. Local plugin sources that overlap the project's managed .agents/plugins directory are rejected before configuration changes. Well-known HTTPS sources remain skill-only:

[[skills]]
name = "find-bugs"
source = "getsentry/skills"              # GitHub shorthand

[[skills]]
name = "review"
source = "getsentry/skills@v1.0.0"       # Pinned to a ref

[[skills]]
name = "gitlab-skill"
source = "https://gitlab.com/group/repo" # GitLab URL

[[skills]]
name = "internal"
source = "git:https://git.corp.dev/repo" # Any git server

[[skills]]
name = "error-tracking"
source = "https://cli.sentry.dev"        # Well-known HTTPS source

[[skills]]
name = "local"
source = "path:./my-skills/local-skill"  # Local directory

Shorthand (owner/repo) resolves to GitHub by default. Set defaultRepositorySource = "gitlab" in agents.toml to resolve to GitLab instead.

Agent Targets

The agents field tells dotagents which tools to configure:

agents = ["claude", "cursor", "codex", "copilot", "grok", "opencode", "pi"]

Pi 0.99+ supports [[mcp]] declarations over stdio and Streamable HTTP. With pi in agents, dotagents writes .pi/mcp.json for project scope and ~/.pi/agent/mcp.json for global scope, or $PI_CODING_AGENT_DIR/mcp.json when overridden (~ is expanded). Existing unrelated servers and top-level settings are preserved. Pi server names allow only letters, digits, underscores, and hyphens. URLs must be literal; ${VAR} references work in headers and environment values. Pi only reads project MCP config after the project is trusted; use pi mcp list --json to check connections and pi mcp login <server> for OAuth. Plugin-bundled MCP is not projected to Pi yet.

Custom subagents are declared with [[subagents]] entries. dotagents writes generated runtime-specific files during install and repairs them during sync:

[[subagents]]
name = "code-reviewer"
source = "getsentry/agent-pack"
targets = ["claude", "codex", "opencode"]

If targets is omitted or empty, dotagents targets every configured agent and warns for agents that do not support custom subagents.

dotagents discovers portable subagent Markdown from conventional source directories such as agents/ and .agents/agents/. The frontmatter supplies the portable name and description; the body supplies the runtime instructions:

---
name: code-reviewer
description: Review code for correctness, security, and missing tests.
---

Review the current diff and return findings with file references.

dotagents can also import native runtime subagent files from .claude/agents/, .cursor/agents/, .codex/agents/*.toml, and .opencode/agents/. Input and matching-runtime output use the same native format: Markdown with YAML frontmatter for Claude, Cursor, and OpenCode; TOML for Codex. Claude and Codex identify agents by name, Cursor can derive name from the filename when omitted, and OpenCode uses the filename as the agent name. Multiple portable matches for the same subagent are rejected as ambiguous, while matching native runtime artifacts are merged. When the source format matches a target runtime, dotagents reuses the native source content for that runtime and only adds its managed-file marker. Other runtimes are generated from the portable name, description, and instructions. Subagent declarations intentionally cover only dependency source and runtime targets, not universal model/tool/permission behavior.

OpenCode reuses an existing project config from .opencode/opencode.jsonc, .opencode/opencode.json, opencode.jsonc, or opencode.json, in that order. New projects use .opencode/opencode.jsonc.

Plugins are declared with [[plugins]] entries. In project scope, dotagents installs canonical bundles into .agents/plugins/<name>/ and generates runtime plugin outputs such as .claude-plugin/marketplace.json, .github/plugin/marketplace.json, .cursor-plugin/marketplace.json, .agents/plugins/marketplace.json, native Claude, Cursor, and Codex manifests, .grok/plugins/<name>/, .opencode/skills/<skill>/, OpenCode MCP entries, and Pi skill links under .agents/skills/<skill>/. During legacy migration, generalized bundles can also project Markdown agents into .opencode/agents/; standard extension agents are preserved but are not projected yet:

[[plugins]]
name = "review-tools"
source = "getsentry/agent-plugins"
path = "plugins/review-tools"
targets = ["claude", "cursor", "codex", "copilot", "grok", "opencode", "pi"]

The canonical portable format is an Agent Plugins v1 bundle: required plugin.json, optional skills/, optional mcp.json, and reverse-domain client extensions. dotagents preserves those portable source files under .agents/plugins/<name>/ and generates isolated target harnesses. OpenCode receives portable MCP servers under managed keys such as plugin.<plugin>.<server>; ${PLUGIN_ROOT} and ${PLUGIN_DATA} are expanded into the installed bundle and persistent .agents/plugin-data/ paths. Generated JSON uses adjacent ownership sidecars, while component symlinks use markers in reserved .dotagents-managed/ directories, so client-owned JSON remains unchanged. Legacy generalized and native Claude/Cursor/Codex manifests remain discoverable during migration. A valid standard root may also coexist with authored native manifests as a hybrid compatibility bundle: the portable root remains the source of truth, reproducible native manifests are ignored in favor of portable generation, and manifests with behavior an adapter cannot represent are retained byte-for-byte only as matching-client fallbacks. Generated adapters are disposable output and are never imported back into the portable core. Native commands, agents, hooks, MCP, and other resources never leak into unrelated targets. Invalid standard roots still fail instead of falling back to legacy parsing.

For bundles with native manifests but no root plugin.json, Codex, Claude, then Cursor order determines the primary manifest. All native manifests are preserved for their matching clients. The primary manifest must be valid; errors in additional manifests block installation only when their client is selected.

Local marketplace entries may use "." or "./" for the source root. An entry with strict: false can supply the plugin manifest when the directory has no plugin.json; dotagents preserves its declared fields in the installed bundle. Native marketplace definitions retain their owning client, so native settings stay with that client while other targets receive portable skills. Saved plugin paths remain pinned across installs.

Global plugins install canonical bundles under ~/.agents/plugins/. Claude and Cursor marketplaces are generated under ~/.agents/. Copilot uses ~/.agents/.github/plugin/marketplace.json, and Codex uses ~/.agents/plugins/marketplace.json. Grok plugins are copied into ~/.grok/plugins/. OpenCode skills are linked into ~/.config/opencode/skills/, and portable MCP servers are merged into ~/.config/opencode/opencode.json. Pi skills are linked into ~/.agents/skills/. --user remains a compatibility alias for --global.

Pi plugin targets are global skill projections rather than isolated plugin installs: a Pi-targeted plugin skill is added to .agents/skills/ and is therefore visible to other clients that consume that shared directory.

Pi reads .agents/skills/ natively. Normal skills need no Pi-specific configuration; plugin bundles can target pi when their skills/ components should be exposed there.

Contributing

git clone git@github.com:getsentry/dotagents.git
cd dotagents
pnpm install
pnpm check  # lint + typecheck + test

Requires Node.js 20+ and pnpm.

This repo is a pnpm workspace with two packages:

• packages/dotagents/ — @sentry/dotagents, the CLI and host library. Owns agents.toml, the .agents/ convention, and the per-agent (Claude/Cursor/etc.) integrations.
• packages/dotagents-lib/ — @sentry/dotagents-lib, the reusable core (SKILL.md and Agent Plugin resolution, source caching, trust validation). Depend on this directly to consume skills or resolve plugins without agents.toml.

Both packages are versioned in lock-step — see RELEASING.md.
