Purpose

Run the read-only check. Do not install Node.js, do not download anything, and do not edit hooks/hooks.json.

This plugin treats a failed row as the truncation hook not running: a truncated WebFetch result then reaches Claude with no added note.

• Pointer: when deciding what a hook that cannot start does to the tool call, fetch hooks: other exit codes live. As of: 2026-10-11. Recheck trigger: that section changes how a hook that cannot start is treated.

Check

Run ${CLAUDE_SKILL_DIR}/scripts/check.sh through Bash, with no arguments; it refuses any. It prints one check<TAB>PASS|FAIL<TAB>detail row each for:

• node: node resolves on PATH, with its version.
• registration: one PostToolUse entry in hooks/hooks.json matches WebFetch and runs node on hooks/webfetch-truncation.mjs, and that file exists. Without node this row is a text match and says so.
• hook: the hook flags a sample WebFetch result that ends in a truncation marker. It runs only when node resolves.

Report the rows as a PASS/FAIL table. On a node FAIL, give the install route from ${CLAUDE_PLUGIN_ROOT}/prerequisites.json. When any row fails, say that the truncation hook is not running in this session. Stop.

Only when the user was about to read a docs page. A failing check has no successor in this plugin.

Gotchas

This skill does not install. A hook notice is not permission to install Node.js or to change the hook registration.
