Running the model locally was the easy partSó em inglês
Pathrule runs a 4B model on your machine to understand your team's knowledge. Getting it to run was a weekend. Getting its output safe to act on took fifty numbered experiments, a frozen evaluation with veto power, and a deterministic compiler that has the final say.
- Engenharia
Introducing Pathrule IntelligenceSó em inglês
A local intelligence layer that learns how your workspace works, how you work, and carries that knowledge across coding agents. Why memory alone is not enough, why retrieval alone is not enough, and what we built instead.
- Engenharia
Persistent Memory for AI Coding Agents: Six DecisionsSó em inglês
Persistent memory for a coding agent is not one product choice. It is six: instruction file or layer, what a memory attaches to, how it is found, where it lives, when it arrives, and how you measure whether any of it worked.
- Engenharia
Memory MCP Servers for AI Coding Agents: What Each One StoresSó em inglês
The protocol's reference server, Mem0, Zep through Graphiti, Supermemory, Basic Memory and what happened to OpenMemory. What each one calls a memory, where it runs, how to wire it into Claude Code, Codex, Cursor and OpenCode, and the one thing MCP does not settle.
- Engenharia
AI Agent Memory: What It Is and How It WorksSó em inglês
AI agent memory is the knowledge an agent can use in a session it did not learn it in. Here is the write path, the read path, the four kinds of memory and the blind spot every retrieval-only system has.
- Engenharia
Best AI Agent Memory Tools for Coding in 2026Só em inglês
Most memory tools are not competing with each other. They store different units for different jobs, and picking the wrong category gives you a tool that works perfectly and still does not help.
- Engenharia
How to Give Codex Persistent Project MemorySó em inglês
Codex supports local memories as well as AGENTS.md. Here is what persists, what teams can share, and where a cross-agent knowledge layer helps.
- Engenharia
Vector RAG vs Path-Scoped Context for AI CodingSó em inglês
RAG is the right tool for a corpus you search. A codebase is not a corpus you search; it is a tree you are standing somewhere in, and the position you are standing in already tells you what matters.
- Engenharia
How Do You Know the Fix Actually Worked?Só em inglês
Merging is a claim, not evidence. The runtime that reported the problem is the only thing that can say whether it stopped happening, and the honest answer has more than two states.
- Engenharia
Pathrule vs Supermemory: A Memory API Answers When AskedSó em inglês
Supermemory is a good memory API and Pathrule is not competing to be one. The difference is delivery: retrieval waits for an agent to think of asking, and path-scoped context arrives before the first tool call.
- Engenharia
What a Pathrule Pattern Is, and Why It Is Not a SkillSó em inglês
A pattern is not a single skill or rule. It is a small, opinionated bundle of memories, rules, and skills for one topic, each piece pre-scoped to the path it belongs to. Here is what that buys you and why the unit is bigger than a file.
- Segurança
Secure-by-Default Scaffolding for AI Coding AgentsSó em inglês
A coding agent writes the first draft now, and the easy default is almost always the insecure one. Here is how a security pattern puts the secure default in front of the agent before it writes a single line.
- Engenharia
One Import Token, Scoped Across Your TreeSó em inglês
Sharing conventions usually means pasting a long file at the root. A pattern is imported with one token that expands into scoped pieces, each placed at the path it applies to. Here is why that difference matters.
- Engenharia
Why a Context Layer Should Have an Open CoreSó em inglês
A local knowledge store, readable integrations and an honest source boundary. What Pathrule keeps open, and where the proprietary Intelligence Engine and Cloud begin.
- Segurança
Where Your AI Context Layer Should Be Allowed to RunSó em inglês
For regulated and security-reviewed teams, the hard question about a context layer is not only what it stores. It is where it runs and who controls the data. Here is how to think about that line.
- Engenharia
Context Engineering vs Prompt Engineering: What Actually ChangedSó em inglês
Prompt engineering tunes the question. Context engineering decides what the model sees before it answers. Here is the difference, why it matters for coding agents, and how teams put it into practice.
- Engenharia
What Is the Model Context Protocol (MCP) and Why Teams Use ItSó em inglês
MCP is the open standard that lets AI assistants talk to external tools and data sources. Here is what it is, how clients and servers fit together, and where a team context layer plugs in.
- Engenharia
Managing AI Coding Context in a MonorepoSó em inglês
A monorepo holds many projects under one root, which is exactly where a single AI instruction file breaks. Here is how to scope context per package so the assistant gets the right rules for the folder it is in.
- Engenharia
GitHub Copilot Custom Instructions: What They Cover and Where They StopSó em inglês
What Copilot’s repository and path-specific instructions handle, and where a shared knowledge layer adds versioned authoring and cross-agent delivery.
- Engenharia
Why AI Coding Assistants Forget Your Codebase Between SessionsSó em inglês
AI coding assistants are stateless. Each new session starts from zero. Here is what actually persists, what does not, and how teams keep context across sessions.
- Engenharia
How to Share Claude Code Memory Across a TeamSó em inglês
Claude Code stores memory per project and per user by default. Here is how teams actually share that knowledge: what CLAUDE.md covers, where it stops, and what fills the gap.
- Segurança
Claude Code Hooks vs CLAUDE.md: Where Enforcement LivesSó em inglês
CLAUDE.md is advisory. Hooks are deterministic. Here is the practical split, why teams should use both, and where a path-scoped knowledge layer fits.
- Engenharia
Why Claude Code Skills Do Not ActivateSó em inglês
Skills look like they install cleanly and then quietly do nothing. Here is why SKILL.md often fails to activate and what a working delivery path looks like.
- Engenharia
Why Cursor Rules Get Silently IgnoredSó em inglês
Cursor rules look loaded and then quietly do nothing. Here is what breaks, what to check first, and how a path-scoped layer keeps rules visible at the moment they matter.
- Engenharia
Why Claude Code Ignores CLAUDE.mdSó em inglês
CLAUDE.md is guidance, not enforcement. Learn why AI coding assistants skip long instruction files and how hooks plus path-scoped rules close the gap.
- Engenharia
AGENTS.md vs Pathrule: When Each One Makes SenseSó em inglês
AGENTS.md gives AI coding agents one predictable file. Pathrule keeps it short by routing the right team knowledge slice per session.
- Engenharia
Context Is a Team Interface, Not a Prompt FileSó em inglês
A practical argument for treating AI context as shared team infrastructure, not another prompt file to maintain by hand.
- Segurança
Why AI Coding Assistants Need Scoped RulesSó em inglês
Learn why AI coding rules work best when they are attached to the files and folders where they apply, reducing noise while preserving precise constraints.
- Custo de tokens
The Cost of Rediscovering Your Own CodebaseSó em inglês
AI coding sessions often waste time and tokens rebuilding knowledge the team already has. Scoped context changes the first move.
- Engenharia
From Tribal Knowledge to Reviewable MemorySó em inglês
Learn how teams turn scattered project knowledge into visible, scoped and reviewable memory that AI coding agents can reuse across sessions and tools.
- Segurança
A Practical Model for Safer AI Coding WorkflowsSó em inglês
Build safer AI coding workflows with explicit boundaries, scoped rules, reviewable memory, source-code privacy and clear human approval points for teams.
- Engenharia
Why Global AI Instructions Break Down at Team ScaleSó em inglês
Learn why global AI instruction files lose signal as teams add more paths and exceptions, and how scoped context keeps local constraints precise for teams.
- Engenharia
Just-in-Time Context for AI Coding AgentsSó em inglês
AI coding agents work better when relevant team knowledge arrives before the first useful action, not after a search loop.
- Engenharia
Memory, Rules, and Skills: Three Kinds of Team KnowledgeSó em inglês
Pathrule separates team knowledge into memories, rules, and skills so AI coding assistants receive the right kind of context.
- Segurança
How Stale Team Knowledge Creates AI MistakesSó em inglês
Learn how stale team knowledge creates repeat AI coding mistakes, then use review, repair and retirement workflows to keep shared context trustworthy.
- Engenharia
One Knowledge Layer Across AI Coding AgentsSó em inglês
Teams should not rewrite the same guidance for every AI coding agent. Pathrule gives shared product knowledge one home across supported coding agents.
- Engenharia
Design Rules Should Travel With the Work, Not the ToolSó em inglês
Keep AI-generated interfaces consistent by attaching product and design rules to the work itself, so the same constraints follow every coding tool you use.
- Engenharia
Team Memory Should Not Change When AI Tools DoSó em inglês
Keep team memory stable while engineers switch AI coding tools, so shared decisions and conventions remain portable across agents, sessions and editors.
- Segurança
Audit Trails for AI Coding: What Changed, Who, and WhySó em inglês
An audit trail for AI coding shows who changed a rule, memory, or skill, when, and why. Here is why the context your assistants act on deserves the same review and history as code.
- Segurança
Pathrule Stores Team Knowledge, Not Source CodeSó em inglês
Pathrule is built around a narrow privacy boundary: store the knowledge teams choose to write down, not their repository source.
- Engenharia
Small Teams Should Build a Context Layer EarlySó em inglês
Small teams feel AI context problems early. Capturing knowledge before the team grows keeps onboarding, review, and AI work calmer.
- Custo de tokens
More Context Is Not Always Better for AI AssistantsSó em inglês
AI assistants do not need every fact at once. They need the right context, at the right depth, for the task in front of them.
- Estudos de caso
