feat(skills): add design-md skill for Google's DESIGN.md spec#14876
Merged
Conversation
Port from anomalyco/opencode#23770: expose a new `tool_output` config section so users can tune the hardcoded truncation caps that apply to terminal output and read_file pagination. Three knobs under `tool_output`: - max_bytes (default 50_000) — terminal stdout/stderr cap - max_lines (default 2000) — read_file pagination cap - max_line_length (default 2000) — per-line cap in line-numbered view All three keep their existing hardcoded values as defaults, so behaviour is unchanged when the section is absent. Power users on big-context models can raise them; small-context local models can lower them. Implementation: - New `tools/tool_output_limits.py` reads the section with defensive fallback (missing/invalid values → defaults, never raises). - `tools/terminal_tool.py` MAX_OUTPUT_CHARS now comes from get_max_bytes(). - `tools/file_operations.py` normalize_read_pagination() and _add_line_numbers() now pull the limits at call time. - `hermes_cli/config.py` DEFAULT_CONFIG gains the `tool_output` section so `hermes setup` writes defaults into fresh configs. - Docs page `user-guide/configuration.md` gains a "Tool Output Truncation Limits" section with large-context and small-context example configs. Tests (18 new in tests/tools/test_tool_output_limits.py): - Default resolution with missing / malformed / non-dict config. - Full and partial user overrides. - Coercion of bad values (None, negative, wrong type, str int). - Shortcut accessors delegate correctly. - DEFAULT_CONFIG exposes the section with the right defaults. - Integration: normalize_read_pagination clamps to the configured max_lines.
Built-in skill under skills/creative/ that teaches the agent to author, lint, diff, and export DESIGN.md files — Google's open-source (Apache-2.0) format for describing a visual identity to coding agents. Covers: - YAML front matter + markdown body anatomy - Full token schema (colors, typography, rounded, spacing, components) - Canonical section order + duplicate-heading rejection - Component property whitelist + variants-as-siblings pattern - CLI workflow via 'npx @google/design.md' (lint/diff/export/spec) - Lint rule reference including WCAG contrast checks - Common YAML pitfalls (quoted hex, negative dimensions, dotted refs) - Starter template at templates/starter.md Package verified live on npm (@google/design.md@0.1.1).

Summary
Hermes now speaks DESIGN.md — Google's freshly open-sourced (Apache-2.0) format for pinning a visual identity to a file that any coding agent can read. New built-in skill under
skills/creative/that kicks in automatically on design / UI / tokens / WCAG tasks.What this unlocks
npx @google/design.md export --format tailwinddrops a Tailwind theme straight out of the spec. W3C DTCG export for design-tool interop too.textColor/backgroundColorpair.Changes
skills/creative/design-md/SKILL.md— full authoring + CLI workflow, token schema, canonical section order, component variant rules, YAML pitfallsskills/creative/design-md/templates/starter.md— parseable starter DESIGN.md with palette, type scale, spacing, and component examples (button variants, card)Validation
