Session reports for Claude Code & Codex to improve your code
594 followers
Keep up with your agents. Spotlight reads your Claude Code and Codex sessions and shows you what your agents actually did, and how to get recursively better every session: what to fix now, what to ship better next time, what's worth sharing. One harness or seven, solo or across your team. Free.
Been waiting for a product like this to arrive. Coding agents broke the feedback loop that used to make engineers better. You don't write the code, you don't review most of it, so where does the learning come from? Everything in the stack accelerates output; nothing closes the loop back to the human. Session reports as a feedback mechanism (not just an audit trail) is the right shape for that. The "what's worth keeping" part matters more than the scary findings, IMO.

@kcpike framing this! S/O to ?makers for building this
@kcpike "Nothing closes the loop back to the human" is the cleanest statement of the problem I've seen yet. :) That's exactly it: review used to be where engineers got better, and agents quietly took that away while speeding everything else up.
@kcpike 1000% Everything is changing under our feet at a crazy rate, so the faster we learn and improve the better we get and the faster we all go! Recursively compounding returns!

300$ for 50min coding. what kind of models are you running? 😅 How does it get recursivly better for each session i dont get it? reminds off entire.io
@conduit_design Ha, right?! The wild part: that's the agents' own tab, we just hand you the receipt. It's crazy how quickly token usage accelerates when you're running multiple subagents on an intensive job, and Fable pricing is going to make this even more fun for all of us soon. 😅
On "recursively better," the idea is that it's a loop with you in it. The model never changes; your setup does. Each report turns what happened into concrete and actionable advice: a fix to apply, a CLAUDE.md line to include, a Skill to draft. Your agent loads that richer setup next session and starts more informed than the last one.

@gogogadgetneil Yeah but thats a slippery slope. You can load all the prerequsite gotchas you want. but most of the time. a clean slate. a undiluted context window is what you need to solve a task. sometimtes its the non determinstic side of AI that solves things. making it more deterministic can have it go down the same rabit holes that lead no where. and actually burn more tokens. because it has to deal with some many constraints. if feels oerwhelemed. and does anything to pas the test. even if the result is contrived. On the bill side. I dont get how 55min of coding now cost 300 $. maybe try the asian models? there are ways. ther eis a project called backdoor. that uses asian models in claude code etc. Personally I run agents differently altogther, for free. But we can talk about that another time :D
@gogogadgetneil @conduit_design The slippery slope is real, and we're with you -- a context window stuffed with stale gotchas is its own kind of token burn. That's exactly why the reports flag context bloat and call out when something should be condensed or split rather than just added to. The point is a setup that compounds and gets leaner, not a pile that grows until it's unmanageable again 😂 Would love to see what Spotlight says about how you run things, and hear where you think it gets it wrong. That's the feedback we're searching for today!
It is not built for windows right? because i am only seeing for macOS, Linux, and WSL 2.
@daniel_oyetunde Great questions! Windows support is a priority for us now. It's being actively worked on, and we expect to have it out in the very near-term.
@gogogadgetneil why now!!!! not nice though but please next time let it be very inclusive thanks
@daniel_oyetunde Purely sequencing relative to what most of our customers were using. On Windows, WSL 2 support has covered a lot of users so far. That said, we recognize how important Windows support is, and so we're working hard on it to get it out as soon as we can. :)

@odeth_negapatan1 honest answer: the most eye-opening pattern wasn't actually a risk. When we stitched our own sessions together, the scary stuff was there (an API key in a tracked file started this product), but the bigger surprise was how many good moves never traveled. One of us had solved a problem cleanly, in one session, on one machine, and the rest of us kept burning time on the same thing for weeks. Nobody was hiding anything; there was just no surface for the unlock to move across. That discovery was a genuine unlock for us, and is a core part of why Spotlight focuses so heavily on highlighting effective patterns worth sharing..
What I've found fascinating is almost every first report we've watched land in person contains one thing the person would have sworn didn't happen. That moment is kind of the product. Curious what yours catches, if you give it a run. :)

Congrats @antifreeze - this is one of those products that feels obvious once you see it.
I’m using Claude Code/Codex every day right now, and the trade off is you don’t really know what got touched, what got skipped, or what weird security debt just got created. In our space making sure everything is tightened up and polished is a necessity more than ever.
Spotlight makes it clear what actually happened. Every team using agents seriously is going to need this. Bullish.
@armand thank you! "Obvious once you see it" is the best kind of compliment. Excited to hear what Spotlight illuminates for you-- and what you wish it showed. That's the stuff we want to build next!

@antifreeze curious what's on your product roadmap btw? anything you could share here?
@fmerian Ha, fair question. Happy to share the general compass, even if I have to hang on to the detailed map for now. ;-)
The direction is in the name: Spotlight is the visibility and advisory layer, illuminating what's happening. The plan for Backplanes is not just being able to see, but to manage/shape everything your agents do, whether you're an individual user or an enormous organization.
Where we're pushing next with Spotlight, directionally:
Deeper: richer insights on individual sessions as well as richer cross-session and team-level patterns.
Broader: more harnesses and agent surfaces beyond Claude Code and Codex.
Automated: from reports to actions. Today a Spotlight finding hands you advice on how to resolve an issue; over time, more of that loop gets automated.
What I'd love from this thread: tell me which harness you'd want next, or what a report should catch that it doesn't today.
We're building this for builders and creators like you, and nothing steers the roadmap like hearing it straight from you.

@armand exactly! @Spotlight by Backplanes brings clarity to your sessions. it improves your code and makes you a better engineer.

@armand @antifreeze @gogogadgetneil @natwar86 reposted on LinkedIn - let's spread the word!
Hey congrats on the launch!
This looks really promising. I’ve had way too many Claude sessions where I come back after a break and have no clue what just happened in the project. The automatic capture + those session summaries with the “needs review” flags feel like such a sanity saver.
@van_ho : Thanks, Van! "Come back after a break and have no clue what just happened" is exactly the moment we built this for. If you give it a run, I'd love to hear what your first report catches. :)

Spot on! Go to backplanes.com and generate your first report. Curious to have your thoughts about the result 👀
"Recursively better every session" is exactly the missing piece I keep hand-rolling. I write a tiny end-of-session log after every Claude Code run and the gold is always the same: what I had to babysit and why. Automating that and feeding it back as a skill/memory primitive will save hours per week. Free + multi-harness is the right packaging. Following.

Amazing! FYI you can see a sample report here: https://www.backplanes.com/features/session-reports
Curious to have your thoughts about it
@david_marko, the end-of-session log is the certified power-user move, and you've described our origin from the other side: we were hand-rolling the same ritual and got tired of it. :)
If you're open to it, I'd love to see what would happen if you ran your hand-rolled log running for a week alongside Spotlight, and then let us know what your log caught that we missed, or vice versa. That kind of feedback is gold for us, and it sounds like you're exactly the right type of person to give it.
