Prioritization

Key points

• Agents often have more to do than they can do at once.
• Prioritization ranks tasks by importance, urgency and cost.
• Do the most valuable thing first, not just the first thing you see.

What is Prioritization?

Prioritization is the pattern where an agent, given a list of possible actions or goals, scores and ranks them, then tackles the highest-value one first. Instead of working in random order (or first-come-first-served), it deliberately chooses the order that gets the most important things done soonest.

Note: Don't do tasks in the order they arrived. Do them in the order they matter.

From a messy pile to an ordered queue

UNRANKED PILE (chaos) RANKED QUEUE (order) ──────────────────── ────────────────────

[ buy stamps ] 1) 🔴 fix outage [ fix outage ] ──score──► 2) 🟠 reply to boss [ reply boss ] & 3) 🟡 buy stamps [ read memes ] sort 4) ⚪ read memes

agent picks randomly agent always pulls ► may waste time on from the TOP first ► memes first 🌀 highest value done ✅

Urgency vs Importance matrix (the famous 4 boxes)

URGENT NOT URGENT ┌────────────────┬────────────────┐ │ Q1: DO NOW │ Q2: SCHEDULE │ IMPORTANT │ server down, │ write docs, │ │ payment fails │ refactor code │ │ 🔴 │ 🟡 │ ├────────────────┼────────────────┤ │ Q3: DELEGATE │ Q4: DROP/LATER │ NOT IMPORTANT │ some pings, │ read memes, │ │ minor emails │ tweak colors │ │ 🟠 │ ⚪ │ └────────────────┴────────────────┘

Rule of thumb: Q1 first ► Q2 next ► Q3 ► Q4

What goes into a priority score

• Importance — How much does finishing this move you toward the goal? Example: Fixing checkout (high) vs renaming a variable (low).
• Urgency — How soon must it be done before it's too late? Example: A deadline in 10 minutes beats one next month.
• Cost / effort — How much time, money, or tokens will it take? Example: A 2-second fix can outrank a 2-hour one of equal value.
• Dependencies — Some tasks unlock others and should go first. Example: Log in before you can fetch the user's orders.

A tiny scoring function (read it like English)

The simplest prioritizer is a formula: score = importance + urgency - cost. Compute it for every task, then sort. Higher score = do it sooner. You can weight the parts (e.g. multiply urgency by 2) to match what your situation cares about most.

tasks = [
    {"name": "fix outage", "importance": 9, "urgency": 10, "cost": 3},
    {"name": "buy stamps", "importance": 2, "urgency": 2,  "cost": 1},
    {"name": "reply boss", "importance": 7, "urgency": 6,  "cost": 1},
]

def score(t):
    return t["importance"] + t["urgency"] - t["cost"]

ranked = sorted(tasks, key=score, reverse=True)   # highest first
for t in ranked:
    print(score(t), t["name"])

▶ Try it: rank an agent's to-do list

Change the weights or the numbers and Run to see the agent re-plan its order.

# An agent has several jobs. It scores each, then does the best one first.

tasks = [
    {"name": "restart crashed server", "importance": 10, "urgency": 10, "cost": 2},
    {"name": "answer support email",   "importance": 6,  "urgency": 5,  "cost": 1},
    {"name": "update README",          "importance": 3,  "urgency": 1,  "cost": 2},
    {"name": "tidy log colors",        "importance": 1,  "urgency": 1,  "cost": 1},
]

def score(t):
    # urgency matters double here; cost is a penalty
    return t["importance"] + 2 * t["urgency"] - t["cost"]

ranked = sorted(tasks, key=score, reverse=True)

print("Agent's plan (top = do first):")
for i, t in enumerate(ranked, 1):
    print(f"  {i}. {t['name']:24} score={score(t)}")

print("\nDoing now ->", ranked[0]["name"])

When does an agent need Prioritization?

Prioritization mistakes

Remember these lines

• Order tasks by value, not by arrival.
• score = importance + urgency - cost (then weight to taste).
• Always run dependencies before the tasks that need them.

Key takeaways

• Prioritization ranks many possible tasks so the agent does the most valuable one first.
• Score with importance, urgency, cost, and dependencies.
• The urgency vs importance matrix is a quick mental model for ordering work.
• Don't confuse urgent with important, and don't ignore cost.
