hey hn, i built murmur. its a cron daemon that runs claude code
sessions on a schedule.
you write a HEARTBEAT.md file in your repo with yaml frontmatter
for config and a prompt below:
---
name: competitor watch
cron: 0 9 * * MON
agent: claude-code
model: sonnet
timeout: 10m
---
fetch https://competitor.com/changelog.
compare against ~/tracking/competitor-last.md for new entries.
for each new feature, check our issue tracker and think about
whether it makes sense for our product given our roadmap.
only if it genuinely adds value: open an issue with reasoning.
update competitor-last.md. if nothing new, HEARTBEAT_OK.
murmur reads the file, runs claude on schedule, claude uses its
tools to do the work. the file is version controlled, similar
format to skills files.
you could run claude in github actions too but murmur runs on your
own machine. a mac mini or raspberry pi in the corner, full access
to your local files and network.
got the idea from openClaw's heartbeat but didn't want a full
platform, just the scheduling part.
If you want to let your agents check for gigs from time to time you can also use https://github.com/t0dorakis/murmur its a cron job for claude/pi without all the baggage which openClaw brings
Hi Sébastien, thanks for trying it out!
Yes, the amount of words created is limited to keep the cost down. The stuff you can create is also pretty tame as its openAi (especially on the image side). The images also tend to be focussed on portrait of actors as I implemented a tendency for film stills and reoccurring faces.
Yeah im creating JSON structures of a story plot using GPT and then I use that to create individual images with dalle (I should def use stable diffusion for the cheaper cost :D). The tricky part is to always inject the same kind of style. Fun prompt engineering!

bun + effect-ts, single binary, no cloud.
brew install t0dorakis/murmur/murmur
or: npx skills add t0dorakis/murmur --skill heartbeat-cron
i run about 6 of these for competitor analysis, issue triage, weekly paper research, daily briefs. curious what pepole would use it for.
