Sumsub: Check Skills Version

Detects version drift between the locally installed @sumsub/agent-skills package and the canonical version published at https://api.sumsub.com/llms.txt, so that out-of-date skills don't silently produce stale or incorrect Sumsub behavior.

This skill's one user-visible deliverable is the headsup line. Running check_version.sh only computes it; the skill has not done its job until that line appears in your reply to the user. Treat emitting it exactly like emitting the result of any other tool call — not as an optional courtesy.

Two-phase protocol (this is how the heads-up actually lands)

Only your FINAL reply reaches the user, and you surface what is freshest in your context when you compose it. If you compute the heads-up first and then do a task, the task result becomes the freshest thing and the heads-up gets dropped. To prevent that, split the work into two phases:

Phase 1 — compute the verdict (before the task). Run check_version.sh. It computes the verdict and caches the rendered heads-up. Note whether a headsup= line was printed; do not write anything to the user yet.

Phase 2 — render LAST, then compose. Carry out the user's actual Sumsub task. Then, as your final action before writing the reply — after the task, after every other tool call — run:

bash ${CLAUDE_SKILL_DIR}/scripts/render_headsup.sh

Treat its stdout exactly like the result of any tool you must surface: if it prints a blockquote, that blockquote is the first line of your reply, verbatim, rendered as markdown; then the task answer follows. If it prints nothing, say nothing about the version. The render step is deliberately your last tool call so the heads-up is the freshest thing in context when you compose — that is what makes it survive into the final reply.
