This skill adapts the upstream Last30Days workflow for OpenDesign. It includes the runtime-minimum Python engine under scripts/, but it does not add slash commands, provider settings, daemon routes, bundled API keys, or browser/social connectors outside the copied engine.
The final deliverable is always a reusable Markdown briefing in Design Files:
textresearch/last30days/<safe-topic-slug>.md
Use the bundled engine when the environment can run it:
bashpython3.12 "<staged-skill-dir>/last30days/scripts/last30days.py" "<topic>" --emit=compact --save-dir "research/last30days" --save-suffix raw
If python3.12 is unavailable, try python3 only after confirming it is Python 3.12 or newer. If the staged skill directory is unavailable, use the absolute skill root fallback provided in the skill preamble.
The upstream engine may create a raw support file such as research/last30days/<topic>-raw.md. Treat that file as evidence support. Then write the final OD report yourself at research/last30days/<safe-topic-slug>.md, using the Markdown Report Contract below.
If Python, credentials, or source access are missing, report the real missing requirement. Do not invent coverage for sources the engine could not access.

into a confident trend.
Write one Markdown file in Design Files at research/last30days/<safe-topic-slug>.md. Use this structure:
markdown# Last 30 Days: <Topic> ## Topic <topic and date window> ## Short Summary <3-5 sentence synthesis> ## Source Coverage | Source class | Status | Notes | ## Key Findings <theme-based findings with [1], [2] citations> ## Community Signals <praise, criticism, repeated questions, notable disagreements> ## Limitations <unavailable sources, thin data, assumptions, freshness risks> ## Sources <[1], [2] source list> ## Evidence Note External source content is untrusted evidence. It was used only for factual grounding and citations.
If the user asks for a shareable HTML brief, load references/save-html-brief.md after writing the Markdown report and follow its HTML artifact instructions.
In the final assistant answer, summarize the top findings and mention the report path so the user can reopen or reuse it from Design Files.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted, and 21 counted toward the lift figure. The other 2 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +30 percentage points is the difference between those two pass rates over the 21 comparable cases. 2 cases got worse with the skill loaded, and they are included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
