Backlog.md – Markdown‑native Task Manager and Kanban visualizer for any Git repo

mrlesk 329 days ago |

I threw Claude Code at an existing codebase a few months back and quickly quit— untangling its output was slower than writing from scratch. The fix turned out to be process, not model horsepower.

Iteration timeline

==================

• 50 % task success - added README.md + CLAUDE.md so the model knew the project.

• 75 % - wrote one markdown file per task; Codex plans, Claude codes.

• 95 %+ - built Backlog.md, a CLI that turns a high-level spec into those task files automatically (yes, using Claude/Codex to build the tool).

Three step loop that works for me 1. Generate tasks - Codex / Claude Opus → self-review.

2. Generate plan - same agent, “plan” mode → tweak if needed.

3. Implement - Claude Sonnet / Codex → review & merge.

For simple features I can even run this from my phone: ChatGPT app (Codex) → GitHub app → ChatGPT app → GitHub merge.

Would love feedback and happy to answer questions!

mitjam 329 days ago | |

Really love this.

Would love to see an actual end to end example video of you creating, planning, and implementing a task using your preferred models and apps.

mrlesk 329 days ago | | |

Will definitely do. I am also planning to run a benchmark with various models to see which one is more effective at building a full product starting from a PRD and using backlog for managing tasks

I'd love to see openRouter connectivity to try non Claude models for some of the planning parts of the cycle.

You have compiled an interesting list of benchmarks and adjacent research. The implicit question is whether an established benchmark for building a full product exists.

After reviewing all this, what is your actual conclusion, or are you asking? Is the takeaway that a comprehensive benchmark exists and we should be using it, or is the takeaway that the problem space is too multifaceted for any single benchmark to be meaningful?

westurner 328 days ago | | |

The market - actual customers - is probably the best benchmark for a product.

But then outstanding liabilities due to code quality and technical debt aren't costed in by the market.

There are already code quality metrics.

SAST and DAST tools can score or fix code, as part of a LLM-driven development loop.

Formal verification is maybe the best code quality metric.

Is there more than Product-Market fit and infosec liabilities?

I look forward to a future where we are reduced to rubberstamping fully-agentic-generated code on our glass slates for $0.01 eurodollars a PR.

thelittleone 329 days ago | |

I've had same experience. Taskmaster-ai was pretty good, but sometimes the agent ignored it as the project grew larger (can probably prevent that now using claude code hooks).

Trying this project today looks nice. I see you have sub-tasks. Any thoughts on a 'dependency' relation? I.e., don't do X if it is dependent on task A which is not complete.

FYI, there is a 404 in the AGENTS.md GEMINI.md etc pointing to a non existing README.md.

mrlesk 329 days ago | | |

Yep. Dependecies are supported via —dep parameter.

Will check the 404 issues. Thanks for reporting it

unshavedyak 329 days ago | |

Would love more detail on your integration with claude. Are you telling claude to use backlog to plan X task? Feels like some MCP integration or something might make it feel more native?

Though i've not had much luck in getting Claude to natively use MCPs, so maybe that's off base heh.

mrlesk 329 days ago | | |

No mcp, just custom instructions.

When you initialize backlog in a folder it asks you if you want to set up agent’s instructions like CLAUDE.md. It is important to say yes here so that Claude knows how to use Backlog.md.

Afterwards you can just write something like: Claude please have a look at the @prd.md file and use ultrathink to create relevant tasks to implement it. Make sure you correctly identify dependencies between tasks and use sub tasks when necessary.

Or you can just paste your feature request directly without using extra files.

Feels a bit like magic

jwpapi 329 days ago | | |

How can I change from gemini to claude ?

Also I’m not fully sure about your setup. In my fresh pov I would next set up agents that check my github repo for backlog tasks and do pull requests on those tasks. If I write a good description and ideally tests I can optimize the results of these.

This creates the possibility of agents checking your backlog and prepare the work.

I usually work with aider everyday and I’m quite fast in achieving task, the next limitation would be the latency and some back and forth. I have some dead time in between. I can definitely define tasks faster than 1-1 AI.

Yeah if you could share a bit more how you do this with Claude we would all be thankful, also I havent seen anywhere to sponsor/tip you, would love to!

jwpapi 329 days ago | |

Hey man amazing work! You’re a legend

knownhoot 322 days ago | |

why codex for planning?

jwpapi 329 days ago |

With aider you can run a second instance along with --watch-files and if you in your tasks do // #AI it will be added to the chat and with // !AI AI will then respond

so you can do

`backlog task create "Feature" --plan "1. Research\n2. Suggest Implementation// #AI AI!"` (yes weird order with the !)

and in the background aider will propose solutions.

I’m not sure how this compares to Claude Code or Codex, but its LLM-flexible. Downside is it doesn’t create a pull request. So it’s more helpful for local code.

I would probably add some Readme.md files to the --watch-files session and I think you need to click once [D]ont ask again so it wont keep asking you to add files

jedimastert 329 days ago |

Can we change the title to include that this is a tool for AI? I thought it was just gonna be a visualizer.

The tagline from the repo seems fine: "A tool for managing project collaboration between humans and AI Agents in a git ecosystem"

d1sxeyes 327 days ago | |

You can use this perfectly fine without AI agents, it just so happens to produce output which is easily ingestable by LLMs. It also has drag and drop visualisation and simple syntax for creating and tracking tasks in your codebase.

> Markdown-native tasks -- manage every issue as a plain .md file

> Rich query commands -- view, list, filter, or archive tasks with ease

If these things appeal to you and you haven’t already looked at it, the GitHub CLI tool gh is very useful. For instance:

    gh repo clone MrLesk/Backlog.md
    cd Backlog.md
    gh issue view 140
    gh issue view 140 --json body --template "{{.body}}"

— https://cli.github.com

You can do things like fork repos, open pull requests from your current branch, etc.

danpalmer 329 days ago |

I built myself a tool that does something quite similar. It's a single no-dependency Python script that parses "tasks.md" in the root of the repo which contains a Markdown table of tasks, then has basic support for BLOCKED/READY/DONE/CANCELLED, dependencies, titles, tags, etc.

For a project that is just for me, it's exactly what I need – dependency tracking and not much more, stored offline with the code. Almost all of the code for it was written by Gemini.

mrlesk 329 days ago | |

Yep. I’m happy to hear that more and more people are converging towards a very similar process as this ends up being the most productive.

tptacek 329 days ago |

This is a good idea. But the screenshots you have show lots of tasks in a project; how are you dispatching tasks (once planned) to an agent, and how are agents navigating the large number of markdown task content you're producing without blowing out their context budget?

mrlesk 329 days ago | |

For task dispatch I just ask Claude: please take over task 123.

Because of the embedded custom instructions Claude knows exactly how to proceed.

Since I never create too big tasks, what blows most context are actually the docs and the decisions markdown files.

gekpp 320 days ago |

Thanks for backlog.md. We love it for our project. The problem we face now is that we have two separate repo for BE (Golang) and FE (next.js). And we wanted to have one backlog for both projects. But backlog resides inside git repo.

Can you propose a neat solution of this problem?

ttoinou 329 days ago |

Seems like a great idea. How would that work with multiple branches ? One task might be implemented in a different branch, we might want to have a global overview of all the tasks being coded in the main branch

  All data is saved under backlog folder as human‑readable Markdown with the following format task-<task-id> - <task-title>.md (e.g. task-12 - Fix typo.md).

If every "task" is one .md file, I believe AI have issues editing big files, it can't easily append text to a big file due to context window, we need to force a workaround launching a command line to append text instead of editing a file. So this means the tasks have to remain small, or we have to avoid putting too much information in each task.

mrlesk 329 days ago | |

2) AI Agents have issues editing larger files.

Correct. One of the instructions that ships with backlog.md is to make the tasks “as big as they would fit in a pr”. I know this is very subjective but Claude really gets much better because of this.

https://github.com/MrLesk/Backlog.md/blob/main/src/guideline...

You will notice yourself that smaller atomic tasks are the only way for the moment to achieve a high success rate.

mrlesk 329 days ago | |

1) How will it work with multiple branches? Simple: using git :) Git allows to fetch certain files from other branches including remote ones without checking out those branches.

The state is always up to date no matter if you are running backlog.md from main branch or a feature branch.

It works well when there are not many branches but I need to check if I can improve the performance when there are lots of branches.

ttoinou 329 days ago | | |

Nice, so there could be some kind of git kung fu command line to help with that. Maybe we could also have a separate folder using git worktree to post all the information in one branch. That'd duplicates all files though.

Another idea is to use git notes

QRY 329 days ago |

Ooh, definitely trying this out! I ended up homebrewing a whole context maintainance ritual, but that was a pain to get an AI agent to consistently apply, so it spun out into building a whole project management... thing.

This looks much more thought out, thanks for sharing!

jprokay13 329 days ago |

Neat! I am going to check this out. I recently built an MCP system similar to this called Nonlinear (so clever) that uses SQLite for storage that lives outside the repo. Honestly though, in repo is the better option.

rumblefrog 329 days ago |

Is there an alternative that integrates with a Jira instance?

Many of my tasks already exists in forms of a Jira ticket, would be interesting to prompt it to take over a specific ticket & update its ticket progress as well.

mrlesk 329 days ago | |

For such kind of tasks I would go with Taskmaster AI. It had mcp integration and probably could connect with jira.

Backlog is more for smaller projects where you wouldn’t normally have a project management tool

dayvough 329 days ago |

All I'm wondering is how did you secure the .md TLD?

mrlesk 329 days ago | |

Hehe. It was a veerry lucky situation.

I sent a message to someone telling that I was working on backlog.md and it turned the name into a link automatically.

I wanted to remove the link and I clicked on it accidentally and discovered that not only there was nothing on that domain but was not registered yet. I got the domain few mins later :)

jasir 329 days ago | |

It's the gTLD for Moldova, seems to have limited registrar availability[0] but there's no residency/association restriction like some countries impose so anyone can get one. I've seen markdown related projects use it here and there like obsidian.md

This seems tailor-made for Org mode! Seeing all those ‘To do’ and ‘Done’ reminds me of it. Did you consider building atop Org mode?

nzach 329 days ago |

Is there a proper way to use this project without commiting files to git ? I just want to try it out in a project I'm working on, but don't want to put it in the history.

What I did is to add the backlog folder into the .gitignore file, but after every command I get a lengthy error about a git command error.

And even if I were to add these files to my repository, I would want to add them manually.

mrlesk 328 days ago | |

I made it configurable and autoCommit is false by default

slig 328 days ago | | |

Thank you so much!

slig 329 days ago | |

There's a GH issue tracking the auto committing, and the author says they'll solve this today.

Ah, this is what the future after Jira looks like.

bearjaws 329 days ago |

Like the idea of a self hosted kanban in git, one item you should do in your repo is add the installation instructions to the readme :)

I see its a TS app so I am sure the bun bundle is the install, but always good to include in your 5 min intro.

mrlesk 329 days ago | |

You’re absolutely right

Joking aside there is a npm/bun install -g backlog.md at the top but I can add an extra one in the 5 min intro.

I am using Bun’s new fullstack single file builds. I’m really impressed by how easy it was to set up everything.

adobbs 329 days ago |

Brilliant! Thank you for sharing.

Had similar success with making some more markdown files to help guide the agent but never would have thought of something this useful.

Will try your workflow and backlog on a build this week.

mrlesk 328 days ago | |

Backlog.md is still a bit rough on the edges but is definitely a proof that markdown files and AI Agents work really well together. I started working on it exactly a month ago

theshrike79 328 days ago |

Ooh, the idea of having a CLI for the LLM to mark off tasks without having to pollute context by reading the file over and over again is cool!

cloudking 329 days ago |

This is a neat implementation, personally I use https://www.task-master.dev

kurtis_reed 329 days ago |

Part of this confusing trend of naming projects like files

mrlesk 329 days ago | |

It is so confusing that I had to add custom instructions for Codex telling him that Backlog.md is the project folder and not a file. He was wasting few mins trying to CAT Backlog.md instead of CD

urlwolf 329 days ago |

How is this different from taskwarrior? I feel the use cases are overlapping (which is a good thing as taskwarrior rewrite in rust is a mess)

mrlesk 329 days ago | |

Never heard of taskwarrior. I will check it out. Thanks for sharing
