Summary

Two new Y Combinator-grounded entrepreneurial toolbox skills for the agent-skills repository.

yc-default-alive-calculator

Paul Graham's Default Alive / Default Dead framework as a deterministic CLI tool and reusable agent skill. Given monthly revenue, burn rate, cash on hand, and monthly growth rate, computes:

Month-by-month financial projection with growth decay modeling
Runway, burn multiple (ARR-adjusted), months to breakeven
Actionable verdict: ALIVE / DEAD / MARGINAL
Lever identification (growth acceleration, cost reduction, pricing, fundraising)

Files: SKILL.md (full methodology + instructions), scripts/default-alive.py (CLI, zero deps), references/default-alive-framework.md (essay deep-dive), references/yc-fundraising-context.md (strategy guide)

yc-weekly-growth-compass

Paul Graham's Startup = Growth framework as an operational weekly practice tool. Supports single-period and time-series data, benchmarks against YC tiers, and frames decisions through the growth compass question.

Files: SKILL.md (full methodology + compass exercise), scripts/growth-compass.py (CLI, zero deps), references/growth-compass-framework.md (essay breakdown), assets/compound-growth-table.md (reference tables)

Changes

README.md — Added both skills to the index
AGENTS.md — Added trigger keywords for both skills

Both skills follow the Agent Skills open format (agentskills.io) and are fully portable across any agent harness. Python 3.9+ stdlib only — no external dependencies.

fix(bundle-builder): generate umbrella SKILL.md as discoverable entry point 77f9d16ef3

Add Step 0 to the bundle-builder file creation order: generate and
register an umbrella SKILL.md at the bundle root before any sub-skills
are created. The umbrella provides the auto-detectable entry point
with broad trigger conditions, Mermaid flowchart, phase table, and
navigation instructions.

Also update:
- workflow-architect SKILL.md: list umbrella in 'What You Get' and
  update Loading Protocol step 5 to mention registration
- workflow-architect AGENTS.md: add Registration section explaining
  how umbrella and sub-skills are registered via skill_manage()

Closes #52

Add yc-default-alive-calculator and yc-weekly-growth-compass skills 7719ddbc67

Two research-grounded entrepreneurial tools based on Paul Graham's Y Combinator
frameworks, with companion CLI scripts and extensive reference material.

yc-default-alive-calculator:
- Paul Graham's 'Default Alive / Default Dead' framework as a deterministic CLI
- Month-by-month financial projection engine with growth decay modeling
- Burn multiple analysis, lever identification, and actionable verdict
- Zero external dependencies (Python 3.9+ stdlib only)
- 2 reference docs (framework deep-dive, fundraising context)

yc-weekly-growth-compass:
- Paul Graham's 'Startup = Growth' framework as an operational weekly tool
- Single-period and time-series growth rate computation
- YC benchmark classification (1% concerning -> 10%+ outstanding)
- Compound growth projections, doubling time, and decision compass
- Zero external dependencies (Python 3.9+ stdlib only)
- 2 reference docs (framework essay breakdown, compound growth table)

Both skills follow the Agent Skills open format (agentskills.io spec v1.0).
