Filesystem search

terminal-tools provides two structured search tools: terminal_rg (ripgrep for content) and terminal_glob (find files by name/glob). Predicate queries (mtime/size/type) and everything else (tree, stat, du) are just terminal_exec.

When to use what

terminal_rg — content search

ripgrep is fast, gitignore-aware, and has a deep flag surface. The structured wrapper exposes common search flags directly; extra_args accepts additional flags compatible with JSON output. Output modes such as --count and --files-with-matches are not compatible with this structured interface; use the CLI when that output is needed.

Quickstart installs and verifies ripgrep. Existing installations can be repaired with uv run scripts/ensure_ripgrep.py --install from the repository root. The runtime also checks Windows package-manager locations and current registry PATH entries; HIVE_RIPGREP_PATH can select an absolute executable path. Startup logs report the executable and version, or instructions to fix the missing dependency.

If ripgrep is unavailable, terminal_rg returns code="ripgrep_required" without searching by default. For an approximate search, explicitly set allow_fallback=True: this uses Python regex, a limited filetype table, and basename globs, and does not honor .gitignore. Even with opt-in, context, extra_args, unknown filetypes and complex globs require ripgrep and return an error. Inspect fallback_limitations; do not treat approximate results as a gitignore-aware inventory.

With context=N, surrounding lines are returned in context, separate from matches. Both contain path, line, and text; total counts only match entries.

Common patterns

# All Python files containing "TODO"
terminal_rg(pattern="TODO", path=".", type_filter="py")

# Case-insensitive, with context
terminal_rg(pattern="error", path="/var/log", ignore_case=True, context=2)

# Search hidden files (rg ignores them by default)
terminal_rg(pattern="api_key", path="~", hidden=True)

# Don't respect .gitignore (find files git would ignore)
terminal_rg(pattern="generated", path=".", no_ignore=True)

# Multi-line pattern (e.g., function definitions spanning lines)
terminal_rg(pattern=r"def\s+\w+\(.*\n.*\n", path="src", extra_args=["--multiline"])

# Specific filename glob
terminal_rg(pattern="version", path=".", glob="*.toml")

rg flag idioms

See references/ripgrep_cheatsheet.md for the long form.

terminal_glob — find files by name

Lists files matching a glob, gitignore-aware (backed by rg --files). The pattern is widened for you so a bare stem Just Works — the actual glob run is returned as expanded_pattern:

• lk_scan_post_reactors → matched as **/*lk_scan_post_reactors* (recursive substring)
• *.py → matched as **/*.py (recursive by default)
• src/**/*.py → used verbatim

If rg is unavailable, filename search retains a best-effort walk with fallback="python-walk" and a note that .gitignore is not honored.

# Find a file by stem anywhere under a tree
terminal_glob(pattern="lk_scan_post_reactors", path="core/framework/skills")

# All YAML configs under /etc
terminal_glob(pattern="*.yaml", path="/etc")

# Include .gitignored / hidden / build-cache files
terminal_glob(pattern="*.log", path=".", include_ignored=True)

For predicate queries (modified in last N days, larger than N MB, only dirs/symlinks), terminal_glob is the wrong tool — drop to terminal_exec("find ..."). See references/find_predicates.md.

Output truncation

Both tools return truncated: true when output exceeded the inline cap. For terminal_rg, matches were dropped (refine the pattern or narrow the path); for terminal_glob, results past max_results (default 1000) were dropped — the search stops early at the cap, so narrow the pattern rather than raising it. terminal_glob also returns timed_out: true (with the partial results it gathered) when the walk exceeded its deadline.

Anti-patterns

• `terminal_rg` is the project search tool — gitignore-aware and returns structured matches; use it for in-project search as well as raw paths.
• Don't reach for `terminal_glob` to list one directory — terminal_exec("ls -la /path") is shorter.
• Don't use `terminal_exec("grep ...")` when terminal_rg exists — rg is faster, gitignore-aware, and returns structured matches.
• Don't hand-roll `terminal_exec("find ... -name ...")` for a plain name search — use terminal_glob. Reserve terminal_exec("find ...") for mtime/size/type predicates.
