lex-swarm-github

GitHub-specific swarm pipeline for brain-modeled agentic AI. Implements an automated issue processing pipeline with finder/fixer/validator roles, adversarial review, and state-machine-driven issue tracking.

Overview

lex-swarm-github extends the base swarm system with a GitHub-specific workflow. Issues are ingested, claimed by finder agents, fixed by fixer agents, validated by multiple independent validators (adversarial review), and finally attached to a pull request. Each state transition is tracked and labeled.

Pipeline States

received -> found -> fixing -> validating -> approved -> pr_open
                                         -> rejected
                                         -> stale

Agent Roles

Role	Responsibility
finder	Claims and analyzes issues
fixer	Implements fixes
validator	Reviews fixes independently (3 required)
pr_swarm	Manages PR creation and merge

Validation

• Requires 3 independent validator approvals for consensus (adversarial review)
• Maximum 3 fix attempts before max_attempts_exceeded error
• Issues stale after 24 hours without activity

Installation

Add to your Gemfile:

gem 'lex-swarm-github'

Usage

Processing an Issue

require 'legion/extensions/swarm_github'

# 1. Ingest an issue from GitHub
result = Legion::Extensions::SwarmGithub::Runners::GithubSwarm.ingest_issue(
  repo: "LegionIO/lex-tick",
  issue_number: 42,
  title: "Tick mode transition doesn't respect SENTINEL_TIMEOUT",
  labels: ["bug", "tick"]
)
# => { tracked: true, key: "LegionIO/lex-tick#42", state: :received }

# 2. Finder claims it
Legion::Extensions::SwarmGithub::Runners::GithubSwarm.claim_issue(
  key: "LegionIO/lex-tick#42"
)
# => { claimed: true, state: :found }

# 3. Fixer starts work
Legion::Extensions::SwarmGithub::Runners::GithubSwarm.start_fix(
  key: "LegionIO/lex-tick#42"
)
# => { fixing: true, attempt: 1 }

# 4. Validators submit reviews (3 required for consensus)
Legion::Extensions::SwarmGithub::Runners::GithubSwarm.submit_validation(
  key: "LegionIO/lex-tick#42",
  validator: "agent-validator-1",
  approved: true,
  reason: "Fix correctly checks both timeout conditions"
)

# 5. Attach PR when approved
Legion::Extensions::SwarmGithub::Runners::GithubSwarm.attach_pr(
  key: "LegionIO/lex-tick#42",
  pr_number: 99
)
# => { attached: true, pr_number: 99 }

Querying the Pipeline

# Issues by state
Legion::Extensions::SwarmGithub::Runners::GithubSwarm.issues_by_state(state: :validating)

# Full pipeline status
Legion::Extensions::SwarmGithub::Runners::GithubSwarm.pipeline_status
# => { states: { received: 0, found: 1, fixing: 2, validating: 1, ... }, total: 4 }

# Specific issue
Legion::Extensions::SwarmGithub::Runners::GithubSwarm.get_issue(key: "LegionIO/lex-tick#42")

Actors

Actor	Interval	What It Does
StaleIssues	Every 3600s	Marks non-terminal issues as :stale when they have not been updated within STALE_TIMEOUT (86400s), enforcing the stale timeout

Development

bundle install
bundle exec rspec
bundle exec rubocop
