CLI Router

Route the task to the narrowest tool that matches the job. Keep this file small; read references/ only for the tool you need.

Choose The Tool

Tool Use it for Avoid when Reference
fd Fast file and path discovery You need content matches inside files references/fd.md
rg Fast text search across files You need structural or syntax-aware matching references/ripgrep.md
sd Simple literal or regex replacement The change depends on code structure or multiline context beyond regex comfort references/sd.md
comby Lightweight structural rewrites across languages You need full syntax parsing guarantees references/comby.md
ast-grep AST-aware code search, lint, and rewrite You need type-aware or semantic analysis references/ast-grep.md
jq Query and transform JSON The source is YAML-first references/jq.md
yq Query and edit YAML, convert structured formats You need exact comment preservation or full jq parity assumptions references/yq.md
wget Non-interactive download, retry, resume, mirror You need browser automation or interactive login flows references/wget.md
head Quick non-interactive sampling You need interactive search, paging, or follow mode references/head.md
less Interactive paging, search, and follow The flow must stay unattended references/less.md
fzf Interactive fuzzy selection for humans The agent must run headless or deterministically references/fzf.md
difftastic Syntax-aware diffs for human review You need an applicable patch or machine-stable diff format references/difftastic.md
shellcheck Shell linting and safety checks You need formatting rather than diagnostics references/shellcheck.md
scc Repo language inventory, LOC, and rough complexity You need semantic code review or profiling references/scc.md

Escalate Deliberately

  • Use fd for paths, then rg for text.
  • Use sd for simple replacements, comby when regex gets brittle, and ast-grep when syntax precision matters.
  • Use jq for JSON and yq for YAML-first edits or format conversion.
  • Use head for quick samples; switch to less only when a human needs to page or search.
  • Treat fzf, less, and difftastic as human-oriented tools unless the task explicitly benefits from interactive review.

Load More Detail Only When Needed

  • Read references/api-surface.md for command/flag selection across the toolset.
  • Read references/common-use-cases.md for ready-made task patterns.
  • Read references/troubleshooting-workarounds.md for common failure modes.
  • Read the tool-specific reference for examples, sharp edges, and escalation boundaries.
