chain-patterns

Chain patterns for multi-phase pipelines: MCP detection, handoff files, checkpoint-resume, worktree agents, CronCreate monitoring. Use when building or debugging a pipeline skill.

doctor

OrchestKit doctor for health diagnostics across manifest integrity, hook configuration, skill validation, agent frontmatter, MCP server connectivity, CC version compatibility, and permission rules. Reports issues with severity levels and auto-remediation suggestions. Validates component counts, detects orphaned entries, and checks CC version matrix compliance. Use when diagnosing plugin health, troubleshooting configuration issues, or running pre-release checks.

telemetry-inspect

Inspects the OrchestKit telemetry pipeline for the current project — lists all known telemetry files with write counts, sizes, schema status, growth trend, and orphan detection. Use when verifying the observability pipeline is healthy, debugging a missing writer, or auditing which files have schema locks vs. which are drift-vulnerable. Read-only — never modifies telemetry files.

Business Case

Financial frameworks for investment justification and decision support.

When to Use Each Framework

Framework	Use When
ROI	Quick sanity check; time value of money doesn't matter much
NPV	Multi-year investments; gold standard for GO/NO-GO
IRR	Comparing projects competing for the same budget
Payback Period	Leadership asks "how fast do we break even?"
TCO	Build vs. buy; total cost including hidden/ongoing costs
Sensitivity Analysis	High uncertainty; need to stress-test assumptions

Decision Tree

Is the investment multi-year?
  YES → Use NPV (+ IRR to compare alternatives)
  NO  → ROI is sufficient

Is this a build vs. buy decision?
  YES → TCO comparison across all three options
  NO  → Skip TCO, use NPV/ROI

Are assumptions uncertain?
  YES → Add sensitivity analysis (3 scenarios)
  NO  → Base case only

Quick Reference Formulas

ROI = (Net Benefits - Total Costs) / Total Costs × 100%

NPV = Sum(Cash Flow_t / (1 + r)^t) - Initial Investment
  r = discount rate (10% enterprise, 15-20% growth, 25-40% startup)
  Decision: Accept if NPV > 0

IRR = discount rate where NPV = 0
  Decision: Accept if IRR > hurdle rate

Payback Period = Initial Investment / Annual Cash Flow
  Benchmarks: SaaS 6-12 mo, Enterprise platform 12-24 mo, Infra 24-36 mo

TCO = CAPEX + (OPEX × years) + Opportunity Cost + Hidden Costs

Business Case Template

# Business Case: [Project Name]

## Executive Summary
[2-3 sentences: what we're investing in and expected return]

## Financial Analysis

### Investment Required
| Item | One-Time | Annual |
|------|----------|--------|
| Development | $X | |
| License / SaaS | | $X |
| Implementation | $X | |
| Training | $X | |
| Maintenance | | $X |
| **Total** | **$X** | **$X** |

### Expected Benefits
| Benefit | Annual Value | Confidence |
|---------|--------------|------------|
| Time savings (X hrs × $Y/hr) | $X | High |
| Error reduction | $X | Medium |
| Revenue uplift | $X | Low |
| **Total** | **$X** | |

### Key Metrics
| Metric | Value |
|--------|-------|
| 3-Year TCO | $X |
| NPV (10% discount) | $X |
| IRR | X% |
| Payback Period | X months |
| ROI | X% |

## Sensitivity Analysis
| Scenario | Discount Rate | Year 1 Benefits | NPV |
|----------|---------------|-----------------|-----|
| Base case | 10% | $X | $X |
| Conservative | 15% | $X × 0.75 | $X |
| Optimistic | 8% | $X × 1.25 | $X |

## Risk Analysis
| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|

## Recommendation
[GO / NO-GO] — [one-sentence rationale]

TCO: Build vs. Buy vs. Partner

See rules/business-cost-benefit.md for the full 3-year TCO template and hidden cost checklist.

Key hidden costs to never omit:

Category	Build	Buy
Opportunity cost	Yes — team blocked from other work	No
Switching costs	N/A	Yes — vendor lock-in
Downtime risk	You own uptime	Partial SLA coverage
Security/compliance	Your responsibility	Shared

Common Pitfalls

Pitfall	Mitigation
Simple ROI without time value	Always use NPV for multi-year decisions
Ignoring soft costs (training, change mgmt)	Add 30% buffer to implementation estimates
Optimistic benefit estimates	Use conservative estimates, document assumptions
Sunk cost included in forward analysis	Evaluate future costs/benefits only
No sensitivity analysis	Always test conservative + optimistic scenarios
