Devchain v0.9.0 Release Notes

Template update required

To take advantage of skills in your agent workflows, update your project to DevLoop v1.0.6 or later. Go to your project page → Import Configuration and re-import the DevLoop template. The updated template includes skill discovery steps in the SubBSM, Epic Manager, and Coder SOPs.

Skills System

Skills are domain-specific knowledge packs — curated instructions, best practices, and procedures that your AI agents can discover and apply during planning and implementation. Instead of relying solely on general-purpose knowledge, agents now pull in targeted guidance for the task at hand.

Skills are synced from open-source repositories maintained by leading AI labs and engineering teams. Each skill contains structured instructions that agents read and apply as additional context when reviewing plans or writing code.

How it works

Skills follow a discover → attach → consume pattern. The Epic Manager matches relevant skills to each task and attaches them. When the Coder picks up the task, it fetches the skill instructions and applies them as implementation guidance. The SubBSM also uses skills to validate plans against domain best practices.

How Agents Use Skills

Three agents in the DevLoop workflow now integrate with skills at different stages:

Plan validation Task assignment Implementation SubBSM Epic Manager Coder │ │ │ ├─ list_skills() ├─ list_skills() ├─ get_skill(slug) ├─ get_skill() x 3-5 ├─ match to task domain ├─ read instructionContent ├─ read instructionContent ├─ update_epic(skillsRequired)├─ apply as guidance └─ validate plan against └─ attach skills to task └─ implement with context domain best practices

SubBSM (Technical Lead)

Before reviewing a draft plan, the SubBSM discovers skills relevant to the plan's domain (e.g., security skills for auth plans, testing skills for test plans) and uses their guidance to strengthen or challenge the proposed approach.

Epic Manager

Before assigning a sub-epic to the Coder, the Epic Manager scans available skills and attaches relevant ones to the task via skillsRequired. This acts as a knowledge briefing for the implementing agent.

Coder

When picking up a task, the Coder checks for attached skills and fetches their full instruction content. These instructions are applied as additional implementation guidance alongside the task's acceptance criteria and project standards.

Skill Sources

Skills are synced from curated open-source repositories. Each source can be individually enabled or disabled per project from the Skills management page.

Anthropic

Skills from the Anthropic skills repository

OpenAI

Curated skills from the OpenAI skills collection

Vercel

Agent skills from Vercel Labs

Trail of Bits

Security-focused skills from Trail of Bits

Microsoft

Skills from Microsoft's GitHub skills

Skills sync automatically on startup and can be manually triggered from the UI. Each skill tracks its source commit for version awareness.

Skills Management

A dedicated management page lets you browse, search, and control which skills are available to your project's agents.

Browse skills, toggle sources, and manage availability per project

What you can do

Browse all synced skills with search across name, description, and category
Enable or disable individual skills per project
Enable or disable entire sources at once
View full skill details including instructions, resources, and metadata
Monitor usage statistics to see which skills your agents are using
Trigger manual sync to pull the latest skills from all sources

MCP Tools

Two new tools are exposed via MCP for agents to interact with skills:

devchain_list_skills

Discover available skills with optional keyword search. Returns skill slug, name, source, category, and description. Only returns skills that are enabled for the project.

devchain_get_skill

Fetch full skill details by slug (e.g., anthropic/code-review). Returns the complete instruction content, resources, license, and metadata. Records usage for analytics.
