Share a week of field notes and photos with Claude Cowork; it writes Mastodon posts with image descriptions, leaves out sensitive locations and saves drafts in Tareno for your approval.
Can Claude Cowork turn field notes and photos into Mastodon posts for a nature reserve?
Yes. Claude Cowork reads the week's notes in a shared folder, picks three observations worth sharing, writes posts with image descriptions, leaves out locations of sensitive species and saves drafts through Tareno. A ranger checks species and counts. Scheduling stays pending until you approve it in Tareno.
Nature reserves and wildlife trusts have rangers who write everything down and almost no time to post. Their notes hold the best content: the first swallows of the year, a fox den found on the western edge, the water level in the pond. Mastodon is where many naturalists and conservation people are, and its communities value accurate species names and image descriptions. Claude Cowork works on a folder of notes and photos and can turn a week of them into posts. This page follows a small reserve through a weekly routine, with the single most important rule for this subject: sensitive locations stay out.
Example: a wetland reserve posts three observations a week
Imagine a ranger who drops her weekly notes and six photos into a Cowork folder. Cowork reads the notes, picks three observations — the first lapwing chicks, a rising water level and a grass snake sunning — and writes a post for each within 450 characters. It notices that one note gives the exact grid reference of the lapwing nests and leaves it out, using only the name of the reserve. It drafts a description for each photo from her notes, finds the files with list_media, and saves three drafts with create_drafts for the reserve's account. She checks species and counts.
Step by step
01
Share the notes and the photos
Put the week's notes and the photos in one Cowork task. A short sentence per photo in the notes gives Cowork what it needs to write a description.
02
Choose three observations
Ask for the three most shareable observations with the line of the notes each comes from. A reserve that posts every day trains followers to scroll past.
03
Strip sensitive locations
Tell Cowork to remove grid references, nest sites and anything that could lead a visitor to a vulnerable species. Name the reserve, not the spot.
04
Write the posts and descriptions
Request a post per observation within 450 characters and a description per photo, written from your notes, because Cowork cannot see the images. Check each against the photo.
05
Save the drafts
Cowork finds the photos with list_media, confirms the account with list_accounts and saves the drafts through create_drafts. Mastodon servers set their own limits, so check yours.
06
Space the requests and approve
Give three days and an IANA time zone. Mastodon's documentation requires scheduled posts to be at least 5 minutes ahead; approve each request in the Tareno dashboard.

Pick the observations
Read this week's field notes in the shared folder as source for Tareno drafts and choose the three most shareable observations for the public, each with the line of the notes it comes from. Flag every line that contains a grid reference, a nest site or another location I should not publish.
Write posts and descriptions
For each chosen observation write a Mastodon post within 450 characters and a description for the matching photo, using only my notes and the reserve name as the place. Say clearly that you cannot see the photos, so I will check each description against the image.
Check species and counts
List every species name and every count in the three posts together with the note it comes from, and mark any name written in two ways or any count that differs between notes. Do not change anything, and tell me what you are unsure about.
Save the drafts
Use Tareno to find the photos [lapwing-1, water-2, snake-1] in my media library, confirm the reserve's Mastodon account [handle@server] and save the three approved posts as drafts with their photos. Return a table with draft ID and observation, and request no time yet.
Mastodon limits and tools in Tareno
Text
up to 500 characters; hashtags and mentions are supported; plain text, no rich formatting
Images
jpg, png, gif, webp, up to 40 MB each, up to 4 per post
Video
mp4, mov, webm, 0 to 10 min, up to 50 MB, one video per post
Links
links can sit inside the text and get a preview card
What Tareno can read
posts published outside Tareno: no; comments: no; transcripts: no; video download: no
As configured in Tareno on 2026-10-24. The live rules for your own account come from the get_platform_schema tool.
What Mastodon itself documents
Character and media limits are set by each server, not by Mastodon itself. The documentation's example server allows 500 characters and 4 attachments, and counts every link as 23 characters.
A scheduled status must lie at least 5 minutes in the future, and a poll cannot be combined with media attachments.
Visibility can be public, unlisted, private (followers only) or direct, and a content warning can be set with spoiler text.
Tareno's configuration for Mastodon allows up to four images with a description each, and the Mastodon community expects descriptions, which suits a photo-based nature account.
Mastodon's documentation says character limits and media limits are set per server, with 500 characters and four attachments as the example, so check your own server.
Tareno gives links an automatic preview on Mastodon, so a post can link to the reserve's visitor information.
Tareno does not read posts or replies on Mastodon, so the ranger reads questions in the app and answers there.
What does not work
Claude Cowork cannot see the photos, so it writes descriptions from your notes and you check each against the image.
It cannot judge which locations are sensitive for a species, so the ranger decides what stays out.
It cannot publish a post on its own, since a time request becomes a post only after you approve it in the Tareno dashboard.
Mistakes to avoid
Publishing a nest site. Name the reserve, not the spot.
Posting every sighting. Three a week is a rhythm followers can keep up with.
Trusting descriptions written without seeing the photo. Compare each.
Counting from a note written in a hurry. Check counts against the original entry.
Open the published Tareno listing, choose install or connect, and complete the Tareno login. Enable Tareno in a new conversation. For Claude, search for Tareno in the supported plugin directory.
Choose OAuth, connect and sign in with your own Tareno account. Check the requested permissions. Refresh the client's tool list after authorization.
Run list_accounts first. Confirm the returned workspace and account IDs before creating a draft. If no accounts appear, connect a social account in Tareno first.

Use the same Tareno account across supported clients. Open the relevant setup guide for authentication, first use, reconnect, and revocation.
You tell it which details to remove, and it flags every line with a grid reference or nest location. It cannot know which species are vulnerable, so the ranger reads the posts before approval.
Can Cowork identify species from photos?
No, and it cannot see them. Species names come from your notes. Cowork reports names written in two ways and counts that differ between notes, so you can correct the record before the post.
How many posts a week?
Three is a comfortable rhythm for a small reserve. Cowork picks the strongest observations from the notes and tells you which ones it left out, so you can swap one for another.
Are image descriptions required?
Not by the software, but the community expects them, and Tareno takes a description per image. Cowork drafts one from your notes, and you correct it against the photo.
What if our server has a smaller limit than 500 characters?
Tell Cowork the limit and it shortens each post accordingly. Mastodon's documentation says limits are set per server, so the figure in Tareno's configuration is only an assumption.
Will the posts go live without my approval?
No. A scheduling request becomes a pending action in Tareno, and Mastodon receives each post only after you approve it in the dashboard. `get_action_status` shows what happened afterwards.
