Progressive Disclosure Shapes Claude Code Output

Opus 5.5 adds progressive disclosure to Claude Code, making replies answer first and enabling output style, scoped rules, auto memory and a UserPromptSubmit hook.
Claude’s latest Opus 5.5 update, released on 22 September, rewrites how Claude Code structures its replies. The new “progressive disclosure” model forces each response to declare its kind first, then applies a set of reply‑shape rules and checks that tailor the output. The result is a more concise style – answers appear up front, with supporting details fetched only when needed – and a dramatic cut in token consumption.
The change builds on the skill‑based architecture described in the Claude‑skills‑cli documentation, where a skill is a YAML front‑matter file that points to scripts and markdown implementations. By loading only lightweight metadata (titles, dates, token counts) at the first layer, Claude Code can defer full content retrieval to a second “details” layer and, if required, a third “deep‑dive” layer that reads original source files. According to the progressive‑disclosure workflow notes, this hierarchy can reduce token usage by up to 98 %, freeing context window capacity for more complex tasks.
Why it matters is twofold. First, the token savings translate into faster, cheaper inference, a benefit for developers who embed Claude Code in IDEs or third‑party agents. Second, the clearer answer‑first format improves the user experience, echoing Anthropic’s recent sprint that accelerated Claude’s desktop UX threefold. As we reported on 23 September, Claude Code’s telemetry handling was recently fixed; Opus 5.5 now adds a substantive architectural upgrade on top of those stability improvements.
Looking ahead, the progressive disclosure framework will likely be extended to other Claude products and third‑party integrations, such as the Amazon seller‑tool beta announced earlier this week. Observers should watch for further refinements to the “kind” taxonomy and for metrics on how the token reductions affect real‑world coding workflows.
