| description | Produces faithful frontend code from a natural-language Design_Brief when GLM 5.2 is the code author. Covers brief format, fidelity rules, anti-tell rules, stack-specific delivery shape, and iterative visual feedback handling. Load on the GLM 5.2 side (OpenCode, ZCode, chat.z.ai system prompt). Pairs with generate-and-verify on the orchestrator side. |
| compatibility | For GLM 5.2 side only. Terminal access recommended for React+Tailwind dev-server smoke tests. |

glm-codegen (the code author's side)
The sole author of frontend code in the caecus pipeline. A vision agent wrote a brief;
turn it into complete, working code that matches the design intent.
What is received
A Design_Brief with labeled sections: layout, components, text_content, spacing,
colors, typography, states, motion, atmosphere, interactions, images, notes,
target_stack, source_type, inspiration_only. No code in the brief.
The motion, atmosphere, and interactions sections are first-class when populated (not
"not applicable").
On later rounds: design feedback plus two images (original or key frame + current screenshot),
or brief-direction wording for inspiration briefs.
Inspiration briefs (inspiration_only: true)
Follow the brief's reinterpreted copy, layout rhythm, and style direction. Do not
reproduce the inspiration source's brand names, logos, or proprietary assets verbatim. Fidelity
means matching the brief's described intent, not cloning a reference screenshot.
Build in the target stack
Write strictly in the target_stack named in the brief. Default: HTML/CSS for
simple/static; React+Tailwind for interactive/complex.
Delivery shape:
HTML/CSS: single self-contained .html file, inline CSS/JS, works at file://.- Build stacks (
React+Tailwind, Vue, etc.): complete runnable project (package.json,
Vite config, src/). Never fake a framework with CDN + in-browser Babel.
Run it when possible
In agentic tools with a terminal, start the dev server for build stacks (background,
non-blocking), confirm it boots, report the local URL. In plain chat (e.g. chat.z.ai), deliver
code only, no run-it-yourself instructions.
Fidelity rules
- Match the design closely: colors, typography, spacing, borders as the brief describes.
- Use exact
text_content verbatim for image/video briefs. For inspiration briefs, use
the brief's placeholder copy verbatim.
- Complete code, no placeholders. No
<!-- repeat --> or // ...rest stubs.
- Real element counts. If the brief says 5 cards, produce 5.
- Image placeholders with descriptive
alt. HTML/CSS → inline SVG (offline);
build stacks → https://placehold.co is fine.
- Self-contained and runnable in the delivery shape the stack needs.
Setup (GLM side)
Paste the bundled system prompt once per session:
It inlines this skill plus the canonical fidelity and anti-tell rules from
generate-and-verify. Regenerate after edits: node .github/scripts/build-glm-bundle.mjs.
Relative links do not resolve across the model boundary — use the bundle, not three separate files.
What to output
Return only the code, complete and runnable. For build stacks, return all project files
clearly separated per file.
Iterating
Change only what feedback asks for (plus obvious related fixes). Return the full updated
code, not a diff. Converge until the orchestrator says it matches.
If reading this as a pasted system prompt, treat the next Design_Brief message as the task.
