Running the model locally was the easy partSolo en inglés
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.
- Ingeniería
Introducing Pathrule IntelligenceSolo en inglés
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.
- Ingeniería
Persistent Memory for AI Coding Agents: Six DecisionsSolo en inglés
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.
- Ingeniería
Memory MCP Servers for AI Coding Agents: What Each One StoresSolo en inglés
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.
- Ingeniería
AI Agent Memory: What It Is and How It WorksSolo en inglés
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.
- Ingeniería
Best AI Agent Memory Tools for Coding in 2026Solo en inglés
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.
- Ingeniería
How to Give Codex Persistent Project MemorySolo en inglés
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.
- Ingeniería
Vector RAG vs Path-Scoped Context for AI CodingSolo en inglés
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.
- Ingeniería
How Do You Know the Fix Actually Worked?Solo en inglés
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.
- Ingeniería
Pathrule vs Supermemory: A Memory API Answers When AskedSolo en inglés
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.
- Ingeniería
What a Pathrule Pattern Is, and Why It Is Not a SkillSolo en inglés
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.
- Seguridad
Secure-by-Default Scaffolding for AI Coding AgentsSolo en inglés
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.
- Ingeniería
One Import Token, Scoped Across Your TreeSolo en inglés
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.
- Ingeniería
Why a Context Layer Should Have an Open CoreSolo en inglés
A local knowledge store, readable integrations and an honest source boundary. What Pathrule keeps open, and where the proprietary Intelligence Engine and Cloud begin.
- Seguridad
Where Your AI Context Layer Should Be Allowed to RunSolo en inglés
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.
- Ingeniería
Context Engineering vs Prompt Engineering: What Actually ChangedSolo en inglés
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.
- Ingeniería
What Is the Model Context Protocol (MCP) and Why Teams Use ItSolo en inglés
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.
- Ingeniería
Managing AI Coding Context in a MonorepoSolo en inglés
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.
- Ingeniería
GitHub Copilot Custom Instructions: What They Cover and Where They StopSolo en inglés
What Copilot’s repository and path-specific instructions handle, and where a shared knowledge layer adds versioned authoring and cross-agent delivery.
- Ingeniería
Why AI Coding Assistants Forget Your Codebase Between SessionsSolo en inglés
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.
- Ingeniería
How to Share Claude Code Memory Across a TeamSolo en inglés
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.
- Seguridad
Claude Code Hooks vs CLAUDE.md: Where Enforcement LivesSolo en inglés
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.
- Ingeniería
Why Claude Code Skills Do Not ActivateSolo en inglés
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.
- Ingeniería
Why Cursor Rules Get Silently IgnoredSolo en inglés
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.
- Ingeniería
Why Claude Code Ignores CLAUDE.mdSolo en inglés
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.
- Ingeniería
AGENTS.md vs Pathrule: When Each One Makes SenseSolo en inglés
AGENTS.md gives AI coding agents one predictable file. Pathrule keeps it short by routing the right team knowledge slice per session.
- Ingeniería
Context Is a Team Interface, Not a Prompt FileSolo en inglés
A practical argument for treating AI context as shared team infrastructure, not another prompt file to maintain by hand.
- Seguridad
Why AI Coding Assistants Need Scoped RulesSolo en inglés
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.
- Costo de tokens
The Cost of Rediscovering Your Own CodebaseSolo en inglés
AI coding sessions often waste time and tokens rebuilding knowledge the team already has. Scoped context changes the first move.
- Ingeniería
From Tribal Knowledge to Reviewable MemorySolo en inglés
Learn how teams turn scattered project knowledge into visible, scoped and reviewable memory that AI coding agents can reuse across sessions and tools.
- Seguridad
A Practical Model for Safer AI Coding WorkflowsSolo en inglés
Build safer AI coding workflows with explicit boundaries, scoped rules, reviewable memory, source-code privacy and clear human approval points for teams.
- Ingeniería
Why Global AI Instructions Break Down at Team ScaleSolo en inglés
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.
- Ingeniería
Just-in-Time Context for AI Coding AgentsSolo en inglés
AI coding agents work better when relevant team knowledge arrives before the first useful action, not after a search loop.
- Ingeniería
Memory, Rules, and Skills: Three Kinds of Team KnowledgeSolo en inglés
Pathrule separates team knowledge into memories, rules, and skills so AI coding assistants receive the right kind of context.
- Seguridad
How Stale Team Knowledge Creates AI MistakesSolo en inglés
Learn how stale team knowledge creates repeat AI coding mistakes, then use review, repair and retirement workflows to keep shared context trustworthy.
- Ingeniería
One Knowledge Layer Across AI Coding AgentsSolo en inglés
Teams should not rewrite the same guidance for every AI coding agent. Pathrule gives shared product knowledge one home across supported coding agents.
- Ingeniería
Design Rules Should Travel With the Work, Not the ToolSolo en inglés
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.
- Ingeniería
Team Memory Should Not Change When AI Tools DoSolo en inglés
Keep team memory stable while engineers switch AI coding tools, so shared decisions and conventions remain portable across agents, sessions and editors.
- Seguridad
Audit Trails for AI Coding: What Changed, Who, and WhySolo en inglés
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.
- Seguridad
Pathrule Stores Team Knowledge, Not Source CodeSolo en inglés
Pathrule is built around a narrow privacy boundary: store the knowledge teams choose to write down, not their repository source.
- Ingeniería
Small Teams Should Build a Context Layer EarlySolo en inglés
Small teams feel AI context problems early. Capturing knowledge before the team grows keeps onboarding, review, and AI work calmer.
- Costo de tokens
More Context Is Not Always Better for AI AssistantsSolo en inglés
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.
