name: tune-system description: Review automation system operation and make conservative adjustments to cadences and thresholds when clearly warranted. Monthly maintenance task.

Tune System

A meta-review skill that analyzes the automation system's own operation and makes conservative, evidence-based adjustments. Mirrors The Unfinishable Map's "Minimal Quantum Interaction" tenet: small, precise interventions with clear justification.

When to Use

• Monthly maintenance: Runs on 30-day cadence (injected when 45 days overdue)
• Post-milestone: After reaching convergence milestones (50%, 75%, etc.)
• Manual invocation: When you notice operational issues
• After significant failures: If failed_tasks count exceeds 5 in a session

Instructions

1. Load Data Sources

Read these files to gather operational data:

obsidian/workflow/evolution-state.yaml  # Primary metrics
obsidian/workflow/changelog.md          # Execution history
obsidian/workflow/todo.md               # Task patterns
obsidian/reviews/                       # Recent review outputs
obsidian/project/project-brief.md       # Project goals (reference)

2. Check Abort Conditions

STOP and escalate to human if any of these are true:

• More than 50% of recent tasks (last 10) failed
• Convergence has regressed for 3+ consecutive sessions
• quality.critical_issues > 0
• Any file read errors during analysis

If aborting, create a minimal report explaining why and skip to step 8.

3. Check Locked Settings

Read evolution-state.yaml for locked_settings section. These settings cannot be modified automatically—note them for the report.

4. Analyze Five Categories

A. Cadence Analysis

Compare last_runs timestamps against cadences settings:

• Calculate days between actual runs for each maintenance task
• Identify tasks frequently overdue (pattern: overdue in >60% of opportunities)
• Identify tasks never reaching cadence (always run early)

Evidence required: 5+ data points (sessions) showing consistent pattern

B. Failure Pattern Analysis

Examine failed_tasks and recent_tasks:

• Count failures by task type
• Look for common error patterns
• Identify environmental issues (missing files, API errors)

Evidence required: 3+ failures of same type or pattern

C. Queue Health Analysis

Examine queue_status and replenishment_source_counts:

• Compare task sources (chain, research, gap, staleness) to execution rates
• Check if certain sources produce tasks that never get executed
• Monitor P3 promotion rate

Evidence required: 5+ sessions of queue data

D. Review Finding Patterns

Scan recent files in reviews/:

• Identify issues raised multiple times but never addressed
• Track issue resolution rate
• Note recurring themes across pessimistic reviews

Evidence required: 3+ reviews showing same pattern

E. Convergence Progress

Analyze progress and quality metrics:

• Calculate convergence rate (% change per session)
• Identify stalled areas (no progress in 3+ sessions)
• Compare current state to convergence_targets

Evidence required: 5+ sessions of convergence data

5. Generate Findings

For each finding, determine the tier:

Tier 1 — Automatic Changes (max 3 per session)

Small, safe adjustments with clear evidence. Apply directly:

| Change Type | Limits | Example | |-------------|--------|---------| | Cadence adjustment | ±2 days | pessimistic-review: 7 → 5 days | | Overdue threshold | ±2 days | validate-all overdue: 2 → 3 days | | Replenishment weight | ±20% | chain source weight: 50 → 60 |

Before applying, verify:

• Setting is not in locked_settings
• Setting hasn't changed in last 60 days (check changelog)
• Clear directional pattern (not random variation)

Tier 2 — Recommendations (log for human approval)

Medium-impact changes:

• New task suggestions (add to todo.md as P3)
• Cadence changes >2 days
• Replenishment mode changes (conservative ↔ aggressive)
• Convergence target adjustments

Tier 3 — Report Only (never automatic)

Changes requiring human judgment:

• Skill instruction modifications
• New skill creation
• Tenet-related adjustments
• Removing vetoed task constraints
• Priority level promotions

6. Apply Tier 1 Changes

For each approved Tier 1 change:

1. Record the previous value
2. Apply the change to the appropriate file
3. Add a comment noting the change date and rationale

Example change to evolution-state.yaml:

cadences:
  pessimistic-review: 5  # Changed from 7 by tune-system 2026-01-08 (overdue 4/5 sessions)

7. Update Evolution State

Add/update these fields in evolution-state.yaml:

last_runs:
  tune-system: [current ISO timestamp]

# Track what was changed for cooldown enforcement
tune_system_history:
  last_run: [ISO timestamp]
  changes_applied:
    - setting: cadences.pessimistic-review
      old_value: 7
      new_value: 5
      date: [ISO date]
      rationale: "Overdue in 4 of 5 recent sessions"

8. Generate Report

Safeguards

Evidence Thresholds

| Analysis Type | Minimum Data Points | |---------------|---------------------| | Cadence patterns | 5 sessions | | Failure patterns | 3 occurrences | | Queue patterns | 5 sessions | | Review patterns | 3 reviews | | Convergence trends | 5 sessions |

Change Cooldowns

After a Tier 1 change, that setting cannot be changed again for:

• 2 tune-system sessions, OR
• 60 days

Check tune_system_history.changes_applied before making any change.

Magnitude Limits

• Cadence: ±2 days maximum
• Threshold: ±2 days maximum
• Weight: ±20 percentage points maximum
• Maximum 3 Tier 1 changes per session

Locked Settings

Human can prevent automatic changes by adding to evolution-state.yaml:

locked_settings:
  cadences.check-tenets: "Locked 2026-01-10 - monthly cadence is intentional"

Important

DO NOT:

• Modify skill instruction files (SKILL.md files)
• Change priority levels (P0-P3) of existing tasks
• Remove items from vetoed tasks
• Modify anything related to tenets
• Make changes without clear evidence (no speculative "improvements")
• Exceed magnitude limits even if evidence seems strong
• Change locked settings
• Run more frequently than monthly (unless manually invoked)

DO:

• Be conservative — when in doubt, recommend rather than apply
• Document everything — all findings, all changes, all rationale
• Respect cooldowns — no rapid oscillation of settings
• Focus on operational parameters — cadences, thresholds, weights
• Generate actionable recommendations for Tier 2/3 items
