# Send Skill Orchestra to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- 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.
## Suggested prompts
### New install

```text
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

```text
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 = "creative"; Regex = "creative|imagine|brainstorm|ideate"; Weight = 0.7 }
    )
}

### Agent Profile Examples

$Global:AgentProfiles = @(
    [AgentProfile]@{
        Name = "GLM-4"
        Competence = @{
            reasoning = 0.85

            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
