×Use Codex with Tareno to compute a weekly air-quality summary from a CSV with a script, check it against threshold values and save a Mastodon post you approve in Tareno.
Yes. Codex writes a small script that computes the week's averages and the days above a threshold from your CSV, shows the output, writes a post that uses only those numbers and saves a draft through Tareno. It does not give health advice. Scheduling stays pending until you approve it in Tareno.

Citizen-science groups and local environmental associations collect readings and then struggle to say anything about them. A weekly summary on Mastodon, where environmental groups are active, would help, but only if the numbers are right and the claims stay within the data. Codex is well suited to the arithmetic part: it writes a script, runs it on the file and reports exactly what came out, including the days with missing readings. The words around the numbers are written afterwards, from the output, never before. This page follows an air-quality monitoring group through a weekly post, with the computation as the center and the clear refusal to give advice.
Imagine a group whose sensor logs one reading per hour in a CSV. Each Monday the volunteer asks Codex to compute, for the past seven days, the mean and maximum of fine particles, the number of hours above the agency's daily guideline value and the number of missing hours. Codex writes the script, runs it, and reports a mean of 11, a maximum of 38 and 14 hours above the guideline, with 9 hours missing on Thursday. It writes a post of 420 characters from those numbers, names the sensor location in general terms, and saves the draft with create_drafts.
Point it at the CSV and state the guideline values and where they come from. A number without its reference is not a finding.
Ask for a small script that computes the mean, maximum and hours above the threshold for the last seven days, and counts missing hours. Codex shows the code and the output.
Missing readings change what the week means. The summary says how many hours were missing, and the post says so.
Request a post that uses only the printed numbers, names the period and the data source and gives no health advice. Mastodon limits are set per server, so confirm yours.
Codex confirms the account with list_accounts and saves the post through create_drafts. Tareno's configuration for Mastodon assumes 500 characters.
Give a day, a time and an IANA time zone. The request becomes a pending action, and you approve it in the Tareno dashboard.
Write and run a script on readings.csv that computes, for the last seven days, the mean and maximum of PM2.5, the number of hours above the guideline value [15 micrograms per cubic metre] and the number of missing hours. Show me the script and the exact output, and do not interpret anything yet.State which guideline value you used, what the file says about units and which hours you counted as missing. If any of these is an assumption rather than something in the file or my message, mark it so I can confirm it before the numbers go into a post.Write a Mastodon post for Tareno within 450 characters from the printed output only: the period, the mean, the maximum, the hours above the guideline and the missing hours, with the sensor's general area.

Because a script gives the same answer every time and shows its work. Codex writes it, runs it on your file and prints the result, so every number in the post can be traced to a line of output.
No. State what was measured and compare it with a named guideline value, but leave the judgment about safety to the authorities. Codex is told not to give advice and to flag any sentence that sounds like it.
Count them and say so in the post. A mean computed from a week with a gap is a different statement from one computed on full data, and followers should know which they are reading.
Yes. Codex can draw a chart with the script, you upload it to the library, and Tareno's configuration allows up to four images. Add a description that states the trend for readers who cannot see it.
Tareno's configuration assumes 500 characters, while Mastodon's documentation says each server sets its own limit. Tell Codex your server's figure so that it counts links and text correctly.
No. A scheduling request becomes a pending action in Tareno, and Mastodon receives the post only after you approve it in the dashboard. `get_action_status` shows what happened afterwards.
