jobs-to-be-done

jobs-to-be-done is a skill for Claude Code, Codex from martineserios/thebrana. It costs 137 tokens per session (3,403 once invoked), scanned A, a copy of jobs-to-be-done, MIT.

A customer-research framework that identifies the progress people are trying to make in a particular situation, rather than focusing only on the product they buy. It considers practical, emotional, and social needs, plus why people switch products.

In plain words
What is it for?
Use it for customer discovery, understanding churn, finding product-market fit, studying switching behavior, and clarifying the problem a product should solve.
Why use it?
It helps explain why customers choose, leave, or ignore a product, including alternatives that are not competing products at all.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

jobs-to-be-done scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Jobs to Be Done Framework

Framework for discovering innovation based on a fundamental truth: customers don't buy products -- they "hire" them to do a specific job in their lives.

Core Principle

Job to Be Done = the progress a customer wants to make in specific circumstances.

Key elements of the definition:

  • Progress (not goal, not solution) -- the customer wants to move from the current state to a better one
  • Circumstances -- context determines the job, not customer attributes (demographics are useless)
  • Hiring/Firing -- the customer actively chooses a product for the "job"

Scoring

Goal: 10/10. Score 1 point per satisfied row in the Quick Diagnostic (7 rows) plus up to 3 points for depth: +1 if all three job dimensions are evidenced, +1 if the job statement avoids any product/solution name, +1 if competition includes non-consumption. Bands: 9-10 = job stated without the product, all four forces mapped, three dimensions evidenced, non-obvious competition and Little Hire tracked; 5-6 = job named but one or two diagnostic rows fail (usually missing forces or emotional/social dimensions); <=3 = product-first framing, demographic segmentation, or Pull-only thinking. Always state the current score and the specific diagnostic rows to fix.

Three Dimensions of Every Job

Every job has three inseparable dimensions -- omitting any means failure:

Dimension Question Example (milkshake)
Functional What does the customer need to do? Occupy myself during a boring commute
Emotional How do they want to feel? Have a small treat for myself
Social How do they want to be perceived? As a sensible parent (not buying donuts)

Framework

1. The Job Statement

Core concept: A job statement captures the progress a customer seeks in a specific circumstance, in a structured format separating context, desired progress, and expected outcome.

Why it works: Because jobs are stable while solutions churn, anchoring on the job protects a roadmap from chasing features that the next technology shift makes irrelevant.
