  tools:
  - name: search_telnyx
    description: Search across the Telnyx knowledge base to find relevant information, code examples, API references,
      and guides. Use this tool when you need to answer questions about Telnyx, find specific documentation, understand
      how features work, or locate implementation details. The search returns contextual content with titles and
      direct links to the documentation pages. If you need the full content of a specific page, use the query_docs_filesystem
      tool to `head` or `cat` the page path (append `.mdx` to the path returned from search — e.g. a result at `/some/page`
      is read with `head -200 /some/page.mdx`).
    inputs:
    - query
  - name: query_docs_filesystem_telnyx
    description: 'Run a read-only shell-like query against a virtualized, in-memory filesystem rooted at `/` that
      contains ONLY the Telnyx documentation pages and OpenAPI specs. This is NOT a shell on any real machine —
      nothing runs on the user''s computer, the server host, or any network. The filesystem is a sandbox backed
      by documentation chunks.


      This is how you read documentation pages: there is no separate "get page" tool. To read a page, pass its `.mdx`
      path to `head` or `cat` — a page at the URL path `/some/page` lives at `/some/page.mdx`. To search the docs
      with exact keyword or regex matches, use `rg`. To understand the docs structure, use `tree` or `ls`.


      **Paths are specific to this site — never guess them.** Discover real paths with `tree / -L 2`, `ls /`, or
      the search tool before reading. If a path does not exist, that only means the guess was wrong; it does NOT
      mean the topic is undocumented — use `rg -il "keyword" /` to find where it is covered.


      **Workflow:** Start with the search tool for broad or conceptual queries like "how to authenticate" or "rate
      limiting". Use this tool when you need exact keyword/regex matching, structural exploration, or to read the
      full content of a specific page by path.


      Supported commands: rg (ripgrep), grep, find, tree, ls, cat, head, tail, stat, wc, sort, uniq, cut, sed, awk,
      jq, plus basic text utilities. No writes, no network, no process control. Run `--help` on any command for
      usage.


      Each call is STATELESS: the working directory always resets to `/` and no shell variables, aliases, or history
      carry over between calls. If you need to operate in a subdirectory, chain commands in one call with `&&` or
      pass absolute paths (e.g., `cd /some-directory && ls` or `ls /some-directory`). Do NOT assume that `cd` in
      one call affects the next call.


      Examples (replace the placeholder paths with real ones from `tree` or search):

      - `tree / -L 2` — see the top-level directory layout

      - `rg -il "rate limit" /` — find all files mentioning "rate limit"

      - `rg -C 3 "apiKey" /some-directory/` — show matches with 3 lines of context around each hit

      - `head -80 /some/page.mdx` — read the top 80 lines of a specific page

      - `head -80 /page-one.mdx /page-two.mdx /section/page-three.mdx` — read multiple pages in one call

      - `cat /some/page.mdx` — read a full page when you need everything

      - `cat /openapi/openapi/source/external/legacy-published/whatsapp/management.json | jq ''.paths | keys''`
      — list OpenAPI endpoints

      Output is truncated to 30KB per call. Prefer targeted `rg -C` or `head -N` over broad `cat` on large files.
      To read only the relevant sections of a large file, use `rg -C 3 "pattern" /path/file.mdx`. Batch multiple
      file reads into a single `head` or `cat` call whenever possible.


      When referencing pages in your response to the user, convert filesystem paths to URL paths by removing the
      `.mdx` extension. For example, `/some/page.mdx` becomes `/some/page`.'
