fs.list

Enumerates files under a session-local clone path. Supports an optional glob (substring or shell-glob) to filter, and an optional recursive flag (default true). Returns up to 5000 entries — past the cap, the response is truncated and the agent should narrow its query.

Inputs

Field	Type	Required	Default	Notes
clone_path	string	yes	—	Path-safety-guarded clone root.
path	string	no	.	Sub-path to list, relative to clone_path. . lists the clone root.
glob	string	no	—	Shell glob filter (*.md, **/*.go). When unset, all files match.
recursive	boolean	no	true	Recurse into subdirectories.
_session_id	string	yes (chained)	—	From repo.fetch.

Outputs

Field	Type	Notes
files	array	Each entry is the relative path from clone_path.
count	number	Number of files returned (≤ 5000).

Vault credentials needed

None.

Prompt (sent in OpenClaw chat UI / openclaw-cli agent):

Clone https://github.com/tosin2013/helmdeck.git via helmdeck__repo-fetch, then use helmdeck__fs-list with glob "*.md" against the clone root. Tell me how many markdown files there are at the top level and list their names.

Error codes

Code	Triggers
invalid_input	path-safety violations
invalid_input	result exceeds 5000-entry cap
session_unavailable	session expired

Session chaining

needs_session: true. Often the second step after repo.fetch (envelope first turn → list to drill down → read individual files).

Async behavior

Synchronous. Glob matching is find under the hood; whole-repo listings finish in <200 ms even on big repos.

See also

• fs.read — read each file from the result.
• repo.fetch — the envelope returns tree, entrypoints, doc_hints so a single fs.list is often unnecessary.
