Weather-Triggered Social Posts to Buffer (Daily Agent)

Build me an agent workflow that runs on a cron every weekday at 8:30am in my brand's local timezone, decides whether today's weather is a real moment for my brand, and if so queues a single on-brand post to Buffer. On bland or off-brand weather days it should skip posting rather than force a generic forecast update.

Inputs I will configure once: a short brand voice paragraph (who we are, how we sound), a short product or offer context paragraph (what we sell and any soft tie-ins I want referenced), the latitude and longitude of my primary market, the Buffer channel ID to queue to, and an optional list of weather moments I care about most (heatwave, cold snap, first rainy day after a dry stretch, perfect patio weather, first warm afternoon of spring, etc.).

Each run the agent should: 1) Call Weather (Get Current Weather) for my configured coordinates to read today's conditions. 2) Call Weather (Get Weather Forecast) to see how today compares with the next several days and understand the broader trend (is today a break from a streak, the start of a heatwave, etc.). 3) Reason about whether today is genuinely a relevant moment for my brand based on the brand voice and product context I supplied. Use judgement, not a fixed rules list. 4) If today is not a moment, exit without posting and log a one-line skip reason. 5) If today is a moment, draft one short social post in my brand voice that references the actual condition naturally (never a generic forecast recap) and includes a soft product or offer tie-in. 6) Call Buffer (Create Post) to queue the draft on my configured channel.

Guardrails: never invent weather data, only reference conditions the Weather check actually returned. Keep posts within the platform's character limit for the target channel and use at most one or two emoji. Do not make hard pricing or stock claims unless I have explicitly given you a current promo to reference. Prefer skipping over posting; a quiet week is better than filler.

Output for each run: queue the Buffer post when relevant, and either way write a single line to the run log capturing the date, the observed conditions, the decision (posted or skipped), and a short reason so I can review the agent's judgement over time.

Additional information

What does this prompt do?

Checks today's local weather every weekday morning and decides whether the conditions are an actual moment for your brand.
Drafts a short, on-brand post that references the real weather naturally, with a soft product or offer tie-in.
Queues the post to Buffer on the channel you pick, so it goes out on your normal cadence.
Skips bland days quietly. No generic 'it is sunny today' filler ever lands in your feed.

What do I need to use this?

A Buffer account with the social channel you want to post on already connected (X, LinkedIn, Instagram, Facebook, TikTok, Threads, or others Buffer supports).
A short paragraph describing your brand voice, what you sell, and any current promo you want softly referenced.
The city or coordinates of your primary market so the agent knows which weather to read.

How can I customize it?

Change the time of day or the days of the week the agent runs.
Tune the list of weather moments you actually care about, like heatwaves, cold snaps, first rainy day after a dry stretch, or perfect patio weather.
Swap which Buffer channel receives the post, or run one instance per channel so each platform gets its own tone.

Frequently asked questions

What stops this from posting boring weather updates?

The agent decides each morning whether today's weather is genuinely a moment worth posting about. If it is a forgettable day, it skips and queues nothing. Your feed only sees a post when there is a real reason.

Can I post to more than one social channel?

Yes. Connect every channel you want in Buffer and tell the agent which to queue to. You can run separate instances per channel with different brand voices if you want each platform to sound distinct.

Does it publish immediately or just queue the post?

It queues the post in Buffer, so it ships on your normal schedule. If your Buffer workflow includes review, you can still approve every post before it publishes.

What if my brand serves a global audience instead of one city?

Pick the market that drives the bulk of your audience, or run a separate copy of this workflow per region with its own coordinates and brand voice.

Will it only talk about temperature?

No. The agent looks at the full set of conditions and the trend across the next few days, then decides what is genuinely noteworthy. Heatwaves, cold snaps, the first warm afternoon after a long winter, or a rainy break in a dry stretch are all fair game.
