Progressive disclosure, final stage: with lazyTools on (default), the eleven browser_* tool schemas stay out of the system prompt — the browser-skill catalog entry is the sole advertisement. One successful skill invocation (model tool call via tools/result, or a /browser-skill user gesture via the session append feed) registers the suite for the process lifetime, idempotent on repeats; session resume is covered by scanning durable events for a past tool/call+tool/result pair (or skill-invocation message) on session entry and at apply time. lazyTools: false keeps the legacy always-on registration. Investigation (recorded in the ticket): tools/result carries normalized name/arguments with an isError discriminant; dsh 0.1 has no official global visibility switch (ctx.tools.restrict is agent-scoped and throws from a plain context), making conditional registration the intended pattern; per-step assembly picks the new suite up on the next step, and visibility changes are first-class inputs of tool-skill's catalog digest. registerTools now returns the combined disposer via a prototype-preserving tracking overlay; the skill prelude tells the model the browser_* tools unlock on skill load. Tests: +8 (hidden-before/reveal/idempotent/gesture/history hit+miss/dispose/ scanner pairing/two-state apply wiring). 124/124 green.
