# Web Fetch

With a URL in hand:

- Static page text: `./ax <url>`; run `./ax agent-context` for the full agent-facing guide
- X/Twitter, Bluesky, YouTube posts/transcripts: `./tgrab <url>`; `./tgrab --help` carries the agent contract

Searching, in this order:

1. `exa` — semantic search with filters, plus extraction in the same call. Default choice: one HTTP round trip, and it returns sources to judge rather than a conclusion to trust. [references/exa.md](references/exa.md)
2. `grok -p "<prompt>"` — tweet search; it has the native X index. Feed the URLs it returns to `./tgrab` when full content is needed.
3. `codex` — escalation, not a first stop: use the environment-appropriate Codex path when the question needs multi-step digging or synthesis across sources, when exa's results are ambiguous and an independent reading helps, or when the 1Password key exa needs is unavailable. [references/codex.md](references/codex.md)

If `ax` or `tgrab` fails, fall back to the host's web fetch/search tool or `curl`.

A browser is the last resort, only for a page the tools above cannot read — JavaScript rendering, a login, or interaction. Which browser to reach for, in order: [references/browser.md](references/browser.md).

Delegate the reading, not only the fetching: hand the whole task to the
environment-appropriate path in the `ask-codex` skill. Inside Codex Desktop or
Codex CLI, use a native subagent; outside Codex, use `codex exec`. Either path
searches on the Codex subscription and returns a digest, so whole pages and JSON
payloads never enter this context. Two things stay here: `exa`, whose 1Password
key no sandbox mode reaches, and anything wanted verbatim, such as the exa docs
pages above, where a digest rewrites the exact names you came for.
