Show HN: CodeLedger – deterministic context and guardrails for AI

https://codeledger.dev
2•ashmivante•5h ago
We’ve been working on a tool called CodeLedger to solve a problem we kept seeing with AI coding agents (Claude Code, Cursor, Codex):

They’re powerful, but on real codebases they: - read too much irrelevant code - edit outside the intended scope - get stuck in loops (fix → test → fail) - drift away from the task - introduce architectural issues that linters don’t catch

The root issue isn’t the model — it’s: - poor context selection - lack of execution guardrails - no visibility at team/org level

---

What CodeLedger does:

It sits between the developer and the agent and:

1) Gives the agent the right files first 2) Keeps the agent inside the task scope 3) Validates output against architecture + constraints

It works deterministically (no embeddings, no cloud, fully local).

---

Example:

Instead of an agent scanning 100–500 files, CodeLedger narrows it down to ~10–25 relevant files before the first edit :contentReference[oaicite:0]{index=0}

---

What we’re seeing so far:

- ~40% faster task completion - ~50% fewer iterations - significant reduction in token usage

---

Works with: Claude Code, Cursor, Codex, Gemini CLI

---

Repo + setup: https://github.com/codeledgerECF/codeledger

Quick start:

npm install -g @codeledger/cli cd your-project codeledger init codeledger activate --task "Fix null handling in user service"

---

Would love feedback from folks using AI coding tools on larger codebases.

Especially curious: - where agents break down for you today - whether context selection or guardrails are the bigger issue - what other issues are you seeing.
