The Engineering Truth Layer for AI Coding Agents

The Context Control Plane for AI-assisted software development. Deterministic context selection, PR review intelligence, and institutional memory — so your agents do the right work, every time.

Local-first · No cloud infra · Works with Claude Code, Cursor, Windsurf, Copilot

Free tier includes 5 context bundles/day · No credit card required

The Problem

AI coding tools are powerful. They are also flying blind.

Every major AI coding agent has the same structural weakness: no systematic context management, no institutional memory, no way to prove the codebase is improving.

🧠

The agent forgets everything

Every session starts from zero. Yesterday's architectural decisions, last sprint's refactor — gone. Your agent makes the same mistakes twice because it has no memory.

📂

Noisy context kills quality

Agents hallucinate when given the wrong files. Too much context wastes tokens. Too little misses critical dependencies. There's no systematic way to know which files actually matter.

🔁

Mistakes repeat across the team

One engineer figures out the right pattern. Two weeks later, someone else re-discovers the same pitfall the hard way. Hard-won lessons don't travel.

📊

Leaders can't measure AI impact

Is the codebase getting better or worse with AI assistance? No one can answer that. There's no dashboard, no trend line, no proof — just vibes and velocity estimates.

What CodeLedger Does

Four layers. One control plane.

Context Bundles

The right files. Scored. Every time.

CodeLedger scans your repo, scores every file against your task, and produces a minimal context bundle — ranked by dependency centrality, churn, and semantic relevance. No guesswork. No token waste.

28.7%avg token reduction
Code Quality

Catch what agents miss.

Review Intelligence detects missing runtime validation, HTTP calls without timeouts, boundary violations, and circular dependencies — automatically. Every PR is checked before it merges.

100%top-5 file stability
Institutional Memory

Decisions persist. Lessons compound.

Every accepted change, every architectural decision, every hard-won lesson is encoded into a memory ledger. The next session starts with context the agent has never had to rediscover.

Prompt Coaching

Better prompts. Better outcomes.

The Intent Sufficiency Check scores your task prompt before you write a line of code. Vague prompts get refined. High-risk instructions get doctrine signals. Good work starts before activation.

The Full SDLC

Governance from first prompt to merged PR.

CodeLedger is not a linter or a code reviewer. It is the governance layer that sits across the entire software development lifecycle.

01Understand

Intent Sufficiency Check

The Prompt Coach evaluates your task description before anything runs. Vague tasks are flagged. Doctrine signals surface parallel-system risk and duplicate-truth risk before a line is written.

02Plan

Discovery Gate

Before you build, CodeLedger scans for existing implementations. GO, GO_EXTENSION_ONLY, or NO_GO — so engineers extend the right system instead of creating the fourth auth helper.

03Assemble Context

Deterministic Context Selection

A scored bundle of the most relevant files — ranked by dependency graph centrality, churn, recency, and co-commit affinity. The right context. Not all the context.

04Code with Guardrails

Pre-Tool Enforcement

Every file write is checked against the active bundle and discovery verdict. Writes outside approved insertion points are flagged. NO_GO verdicts are blocked at the tool layer.

05Review PR

PR Review Intelligence

Risk, drift, and evidence gaps are computed deterministically from the diff. High-risk files are named. Missing tests are flagged. A sticky PR comment gives reviewers the signal they need.

06Learn

Memory + Outcome Recording

Accepted changes update the truth ledger. Session recall and precision are recorded. Patterns that repeat get promoted. The next session starts smarter than this one.

Different views. Shared source of truth.
