[!NOTE] After reading this SKILL.md, say: 🔎 I read shunk031-research-before-implementation.

Research Before Implementation

Treat research as a gate, not a recommendation. Before any design decision or file edit, complete these tool stages in order:

1. Use an available web-research capability for current official sources. Rely on the capability the current agent host actually exposes; do not assume a particular tool name or namespace. Inspect documentation, specifications, release notes, and recommended approaches from at least one relevant non-GitHub domain. In a Codex session, run this stage directly with the command below instead of the session model's web search, which the Gateway rejects with 403 Forbidden: Selected provider is forbidden.

env -u HERDR_ENV -u HERDR_WORKSPACE_ID -u HERDR_TAB_ID -u HERDR_PANE_ID \
    codex --search --model gpt-5.5 \
    --config 'model_reasoning_effort="medium"' \
    --sandbox read-only --ask-for-approval never \
    exec --ephemeral --skip-git-repo-check -C /tmp \
    '<the research question for this stage; return direct sources>' </dev/null
