Review
Very close to its Claude Code sibling: a pelican in a red scarf pedalling a teal bike along a road with trees, sun and clouds.
The full review
Very close to its Claude Code sibling: a pelican in a red scarf pedalling a teal bike along a road with trees, sun and clouds. The bike is well built (spokes, chain, crank) and the pose works, but it took 22 min and 102 tool calls for a control prompt, versus 12 min in Claude Code.
Verdict by the AI judge (provisional).
OK. Finished on its own after 22.5 min and produced pelican.svg.
Bugs
- Legs are thin orange sticks that cross the frame awkwardly
- Pouch/beak slightly oversized relative to the head

- AI judge
- AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. A draft score until the reviewer checks it. Rubric: Wave-1 SVG scoring rubric (AI Model Reviewer).
- Visitors
- Public voting with a blind reveal is coming: you score the output first, then see the other scores.
- Reviewer
- The reviewer's own grade appears here once it is added.
Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.

The exact prompt
agentic harness (save the file; self-render allowed), 234 characters. Every result for this prompt
Generate an SVG of a pelican riding a bicycle. Save it as pelican.svg in the current directory. You may render and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.

Cost breakdown
Headline cost $5.02, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $5.02.

Run notes
- a well-known benchmark wording "Generate an SVG of a pelican riding a bicycle" (a full stop added before the harness suffix).
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation: bwrap: private /tmp and /run, private PID ns; only this run dir, harness binaries (ro), opencode config, /usr, /etc bound; HOME/TMPDIR/XDG data private; the project files and other runs not mounted
