Awesome-Claude-Skills I built 135 Claude Skills with real formulas. Here's what "production-grade" actually means.

#opensource #ai #claude #productivity

I've been frustrated for a long time.

Every "awesome Claude prompts" repo I found looked like this:

"Act as a senior software engineer. Be helpful, thorough, 
and professional. Consider edge cases."
Enter fullscreen mode Exit fullscreen mode

That's not a skill. That's a costume.

Real expertise has frameworks. Named responsibilities.
Actual formulas. Code that runs. Constraints that prevent
the model from giving you the easy wrong answer.

So I spent 6 months building what I actually wanted.

AgentOS 2.0 — 135 production-grade Claude Skills.

This article explains exactly what's inside and why it's
different from every other prompt collection on GitHub.

The Problem With Every Other Prompt Repo

Most prompt repositories fall into one of three traps:

Trap 1: The costume prompt

"You are an expert financial analyst. 
Help the user with their finance questions."
Enter fullscreen mode Exit fullscreen mode

Zero frameworks. Zero formulas. Zero depth.

Trap 2: The instruction dump

"When answering, always:
- Be professional
- Consider multiple angles  
- Cite sources
- Format your response clearly"
Enter fullscreen mode Exit fullscreen mode

This is just asking Claude to be Claude. It changes nothing.

Trap 3: The persona prompt

"You are Alex, a no-nonsense McKinsey consultant 
with 20 years of experience..."
Enter fullscreen mode Exit fullscreen mode

Roleplay, not expertise. The model doesn't suddenly
know DCF models because you named it Alex.

What actually works: Named sub-agents with
distinct responsibilities, actual domain formulas
in code, and explicit forbidden behaviors that
prevent hallucination in critical areas.

Here's what that looks like in practice.

What "Production-Grade" Actually Looks Like

FinanceOracle — The Apex Skill

This is the most complete skill in the repo.
Here's a fraction of what's inside:

12 Sub-Agents:

  • OptionsDesk — derivatives pricing and structuring
  • MacroStrategist — macro regime analysis
  • HedgeFundArchitect — strategy design
  • FamilyOfficeCIO — multi-generational allocation
  • TaxOptimizer — harvest and structure optimization
  • DerivativesStructurer — exotic product design (+ 6 more)

Actual runnable Python:

def black_scholes(S, K, T, r, sigma, option_type='call'):
    d1 = (np.log(S/K) + (r + 0.5*sigma**2)*T) / (sigma*np.sqrt(T))
    d2 = d1 - sigma * np.sqrt(T)

    if option_type == 'call':
        price = S * norm.cdf(d1) - K * np.exp(-r*T) * norm.cdf(d2)
        delta = norm.cdf(d1)
    else:
        price = K * np.exp(-r*T) * norm.cdf(-d2) - S * norm.cdf(-d1)
        delta = -norm.cdf(-d1)

    gamma = norm.pdf(d1) / (S * sigma * np.sqrt(T))
    vega  = S * norm.pdf(d1) * np.sqrt(T) / 100
    theta = (-(S * norm.pdf(d1) * sigma) / (2 * np.sqrt(T))
             - r * K * np.exp(-r*T) * norm.cdf(d2)) / 365

    return {"price": price, "delta": delta, 
            "gamma": gamma, "vega": vega, "theta": theta}
Enter fullscreen mode Exit fullscreen mode

Black-Litterman portfolio construction:

def black_litterman(Sigma, market_weights, views_P, 
                    views_Q, views_omega, tau=0.05, delta=2.5):
    pi = delta * Sigma @ market_weights
    M_inv = np.linalg.inv(
        np.linalg.inv(tau * Sigma) + 
        views_P.T @ np.linalg.inv(views_omega) @ views_P
    )
    mu_bl = M_inv @ (
        np.linalg.inv(tau * Sigma) @ pi + 
        views_P.T @ np.linalg.inv(views_omega) @ views_Q
    )
    return {"expected_returns": mu_bl}
Enter fullscreen mode Exit fullscreen mode

This isn't pseudocode. This runs.

OKREngine — Catches Failures Before They Kill Your Quarter

I've watched two startups waste entire quarters on
broken OKRs. This skill exists because of that.

The objective quality scorer:

def score_okr(objective: str, key_results: list[dict]) -> dict:
    obj_score = 0
    obj_score += 3 if len(objective) < 100 else 0
    obj_score += 3 if not objective.lower().startswith("improve") else 0
    obj_score += 4 if any(w in objective.lower() for w in 
        ["best", "lead", "#1", "transform", "redefine"]) else 0

    kr_scores = []
    for kr in key_results:
        kr_score = 0
        kr_score += 3 if kr.get("metric") else 0
        kr_score += 3 if kr.get("baseline") is not None else 0
        kr_score += 4 if kr.get("target") is not None else 0
        kr_scores.append({
            "kr": kr["text"][:60],
            "score": kr_score,
            "grade": "Good" if kr_score >= 8 else "Needs work"
        })

    return {
        "objective_score": f"{obj_score}/10",
        "key_results": kr_scores,
        "recommendation": "Strong OKR" if obj_score >= 8 else "Needs revision"
    }
Enter fullscreen mode Exit fullscreen mode

The skill also catches the 12 most common OKR failure modes — including sandbagging, health metrics disguised as OKRs, and the single most destructive mistake: tying OKR scores to bonuses.

VentureIntelligence — Term Sheet Red Flag Detector 

def score_term_sheet(terms: dict) -> dict:
    red_flags = []

    if terms.get("liq_pref_multiple", 1) > 1:
        red_flags.append(
            f"Liquidation preference {terms['liq_pref_multiple']}x — above 1x is punishing"
        )
    if terms.get("participating_preferred", False):
        red_flags.append(
            "Participating preferred — VCs get paid twice in exits below threshold"
        )
    if terms.get("anti_dilution") == "full_ratchet":
        red_flags.append(
            "Full ratchet anti-dilution — catastrophic in a down round"
        )
    if terms.get("board_seats_investor", 0) > terms.get("board_seats_founder", 0):
        red_flags.append(
            "Investor has majority board control — you can be fired from your company"
        )

    score = 10 - (len(red_flags) * 3)
    return {
        "score": max(0, score),
        "grade": "Sign it" if score >= 8 else "Negotiate" if score >= 5 else "Get a lawyer NOW",
        "red_flags": red_flags
    }
Enter fullscreen mode Exit fullscreen mode

12 sub-agents including TermSheetDecoder, ValuationNegotiator, ChampionDeveloper, and BoardRelationshipManager.

CrisisIntelligence — War Room OS

Every company will face a crisis. Almost none prepare.

def classify_crisis(crisis: dict) -> dict:
    severity_score = 0

    if crisis["customer_impact_pct"] >= 0.5: severity_score += 30
    if crisis["revenue_at_risk"] >= 1_000_000: severity_score += 20

    coverage = {"none": 0, "local": 5, "national": 15, "viral": 30}
    severity_score += coverage.get(crisis["media_coverage"], 0)

    if crisis["regulatory_involvement"]: severity_score += 15
    if crisis["legal_liability"]: severity_score += 15

    if severity_score >= 70:
        level = "CRITICAL (P0)"
        action = "CEO leads. War room activated NOW."
    elif severity_score >= 40:
        level = "HIGH (P1)"
        action = "VP-level lead. External comms needed."
    else:
        level = "MEDIUM (P2)"
        action = "Director-level. Monitor externally."

    return {
        "level": level,
        "immediate_action": action,
        "time_to_first_response": "1 hour" if severity_score >= 70 else "4 hours"
    }
Enter fullscreen mode Exit fullscreen mode

The 5Rs framework (Recognize → Respond → Responsible → Remediate → Restore) is built into every communication template.

How It Works (60-Second Setup)

Claude.ai Projects:

# 1. Open Claude.ai → Projects → New Project
# 2. Paste SKILL.md into "Project Instructions"  
# 3. Start chatting
Enter fullscreen mode Exit fullscreen mode

Claude Code:

cat finance-oracle/SKILL.md >> .claude/CLAUDE.md
Enter fullscreen mode Exit fullscreen mode

Claude API:

import anthropic

with open("startup-cto/SKILL.md", "r") as f:
    skill = f.read()

client = anthropic.Anthropic()
response = client.messages.create(
    model="claude-sonnet-4-6",
    max_tokens=4096,
    system=skill,
    messages=[{"role": "user", "content": "Audit our tech stack decision"}]
)
Enter fullscreen mode Exit fullscreen mode

That's it. Claude is now that specialist.

Try It Right Now

The fastest way to understand the depth is to try one.

I recommend starting with okr-engine or startup-cto — they're the most complete and immediately useful regardless of what you're building.

Paste the SKILL.md into Claude Projects. Ask it to review your current OKRs or tech stack. You'll see the difference immediately.
