Implementations

impl Environment

pub fn detect() -> Self

Auto-detect the active agent environment from environment variables.

pub fn skill_rel_path(&self, name: &str) -> PathBuf

Return the skill file path pattern for this environment.

Given a skill name, returns the relative path where the skill file should be installed. Each environment has its own convention:

Environment	Path
Claude Code	.claude/skills/{name}/SKILL.md
OpenCode	.opencode/skills/{name}/SKILL.md
Codex	.codex/AGENTS.md
Cursor	.cursor/rules/{name}.md
Generic	AGENTS.md

pub fn all_skill_rel_paths(name: &str) -> Vec<(Environment, PathBuf)>

Return all skill file paths for installing across all environments. Used by install --all to write skill files for every supported harness.

pub fn skill_path(&self, name: &str, root: Option<&Path>) -> PathBuf

Resolve the skill file path under a given root directory.

When root is None, the returned path is relative to CWD.

pub fn rules_dir(&self) -> PathBuf

Return the rules/instruction file directory for this environment.

Environment	Directory
Claude Code	.claude/ (CLAUDE.md lives at root)
Cursor	.cursor/rules/
Windsurf	.windsurf/rules/
Others	.agent/rules/

pub fn runbooks_dir(&self) -> PathBuf

Return the runbooks directory for this environment.

Runbooks use .agent/runbooks/ universally — they’re tool-agnostic.

pub fn memories_dir(&self) -> PathBuf

Return the memories directory for this environment.

Memories use .agent/memories/ universally — they’re tool-agnostic.

pub fn skills_dir(&self) -> PathBuf

Return the skills directory for this environment.

Environment	Directory
Claude Code	.claude/skills/
OpenCode	.opencode/skills/
Cursor	.cursor/rules/ (skills map to rules)
Others	.agent/skills/

impl Environment

pub fn from_name(name: &str) -> Option<Self>

Parse from a string name (for –harness flag).

Trait Implementations

impl Clone for Environment

fn clone(&self) -> Environment

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Environment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Environment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Environment

fn eq(&self, other: &Environment) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
