Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

1. Skill Handbook
Maps context to required skills with demand scores. function Invoke-SkillDemandInference { param( [string]$Context, [hashtable]$SkillHandbook ) $skills = @() # Pattern matching for skill identification foreach ($pattern in $SkillHandbook.Patterns) { if ($Context -match $pattern.Regex) { $skills += @{ Name = $pattern.Skill Demand = $pattern.Weight } } } return $skills }
2. Agent Profiles
Tracks competence and cost per skill for each agent. class AgentProfile { [string]$Name [hashtable]$Competence # skill -> score (0-1) [hashtable]$Cost # skill -> cost (tokens/$) [float]$BaseCost [float]GetScore([string[]]$RequiredSkills, [float[]]$Demands) { $competence = 0 $cost = 0 for ($i = 0; $i -lt $RequiredSkills.Count; $i++) { $skill = $RequiredSkills[$i] $demand = $Demands[$i] $competence += $demand * $this.Competence[$skill] $cost += $demand * $this.Cost[$skill] } return $competence / ($cost + 0.001) # Performance-cost ratio } }
3. Routing Decision
Selects agent that maximizes performance/cost ratio. function Select-OptimalAgent { param( [AgentProfile[]]$Agents, [hashtable[]]$RequiredSkills, [float]$MaxSameAgentRatio = 0.7 ) $skillNames = $RequiredSkills.Name $skillDemands = $RequiredSkills.Demand # Score each agent $scores = @{} foreach ($agent in $Agents) { $scores[$agent.Name] = $agent.GetScore($skillNames, $skillDemands) } # Get best agent $best = $scores.GetEnumerator() | Sort-Object Value -Descending | Select-Object -First 1 # Check for routing collapse (if tracking history) if (Test-RoutingCollapse -Agent $best.Key -Ratio $MaxSameAgentRatio) { # Return second-best $secondBest = $scores.GetEnumerator() | Sort-Object Value -Descending | Select-Object -Skip 1 -First 1 return $secondBest.Key } return $best.Key }
Skill Handbook Definition
$Global:SkillHandbook = @{ Patterns = @( @{ Skill = "reasoning"; Regex = "analyze|decide|evaluate|compare"; Weight = 1.0 }, @{ Skill = "code"; Regex = "code|function|implement|debug"; Weight = 1.0 }, @{ Skill = "research"; Regex = "research|find|search|investigate"; Weight = 0.8 }, @{ Skill = "writing"; Regex = "write|compose|draft|create content"; Weight = 0.9 }, @{ Skill = "math"; Regex = "calculate|compute|solve|equation"; Weight = 1.0 }, @{ Skill = "creative"; Regex = "creative|imagine|brainstorm|ideate"; Weight = 0.7 } ) }
Agent Profile Examples
$Global:AgentProfiles = @( [AgentProfile]@{ Name = "GLM-4" Competence = @{ reasoning = 0.85 code = 0.80 research = 0.75 writing = 0.85 math = 0.80 creative = 0.75 } Cost = @{ reasoning = 1.0 code = 1.0 research = 1.0 writing = 1.0 math = 1.0 creative = 1.0 } BaseCost = 0.001 # $/1K tokens }, [AgentProfile]@{ Name = "GLM-5" Competence = @{ reasoning = 0.95 code = 0.92 research = 0.88 writing = 0.90 math = 0.93 creative = 0.85 } Cost = @{ reasoning = 2.0 code = 2.0 research = 2.0 writing = 2.0 math = 2.0 creative = 2.0 } BaseCost = 0.002 # $/1K tokens } )
Routing Collapse Prevention
$Global:RoutingHistory = [System.Collections.Queue]::new(100) function Test-RoutingCollapse { param( [string]$Agent, [float]$Ratio = 0.7 ) if ($Global:RoutingHistory.Count -lt 10) { return $false } $recent = $Global:RoutingHistory | Select-Object -Last 10 $sameCount = ($recent | Where-Object { $_ -eq $Agent }).Count return ($sameCount / 10) -gt $Ratio } function Register-RoutingDecision { param([string]$Agent) if ($Global:RoutingHistory.Count -ge 100) { $Global:RoutingHistory.Dequeue() } $Global:RoutingHistory.Enqueue($Agent) }
Usage
# Load skill orchestra . skills/skill-orchestra/skill-orchestra-api.ps1 # Route a request $context = "Analyze this code and suggest improvements" $skills = Invoke-SkillDemandInference -Context $context -SkillHandbook $Global:SkillHandbook $agent = Select-OptimalAgent -Agents $Global:AgentProfiles -RequiredSkills $skills Write-Host "Selected agent: $agent" # Output: Selected agent: GLM-5 (high reasoning + code competence)
Integration with Model Router
SkillOrchestra can enhance the existing model-router skill: # In model-router/route-request.ps1 function Route-Request { param([string]$Context) # Use SkillOrchestra for intelligent routing $skills = Invoke-SkillDemandInference -Context $Context $agent = Select-OptimalAgent -Agents $Global:AgentProfiles -RequiredSkills $skills # Register for collapse prevention Register-RoutingDecision -Agent $agent return $agent }
Benefits
+22.5% Accuracy - Better agent-task matching 700x Cheaper Learning - No RL training needed No Routing Collapse - Built-in prevention Interpretable - Explicit skill modeling Cost Control - Performance-cost trade-off
