mece-framework

mece-framework is a skill for Claude Code, Codex from ConrayGambit/Strategy-Consultant-5-Consulting-Frameworks. It costs 58 tokens per session (788 once invoked), scanned A, original, MIT.

A way to divide a problem into categories that do not overlap and together cover everything important. MECE stands for “mutually exclusive, collectively exhaustive.”

In plain words
What is it for?
Breaking down complex problems, checking whether an analysis is complete, and organizing strategic thinking into nested Markdown bullet points.
Why use it?
It prevents counting the same issue twice or overlooking a relevant cause. The result is a clearer structure for analysis and discussion.

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

mece-framework 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 10d 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.

MECE Framework

Concept

MECE — Mutually Exclusive, Collectively Exhaustive — is the foundation of structured problem solving:

  • Mutually Exclusive: No factor belongs in two categories.
  • Collectively Exhaustive: Every relevant factor is captured.

Non-MECE breakdowns look rigorous but aren't — overlapping categories double-count, and missing categories blind you to root causes.

Required output format

Nested Markdown bullets. Top-level bullets are categories in bold; nested bullets are the specific factors under each category.

- **Category 1**
  - Sub-factor A
  - Sub-factor B
- **Category 2**
  - Sub-factor C
  - Sub-factor D

Defaults & flex points

Default When to flex
3–6 top-level categories If the problem has only 2 real categories, use 2 — don't pad. If it has 7, use 7.
2–5 sub-factors per category Use as many as the problem actually contains.
Categories specific to the problem Generic "People/Process/Technology" buckets are a smell — only use them if they genuinely fit.

Rule that doesn't flex: the categories must be MECE. Test each one — could a factor reasonably belong to two? Then merge or split. Could relevant factors not fit anywhere? Then add a category.

Example — logistics

Problem: A regional courier company's on-time delivery rate fell from 94% to 81% in six months.

- **Network capacity**
  - Vehicle fleet utilization (peak hour saturation)
  - Driver headcount vs. demand
  - Hub sortation throughput
- **Routing & dispatch**
  - Algorithm changes after the Q2 system migration
  - Address-data quality (geocoding errors)
  - Manual route overrides by dispatchers
- **Demand pattern shift**
  - New high-volume customer added in Q1
  - Seasonal swing into peak retail months
  - Same-day delivery share rising
- **Workforce**
  - Driver turnover and onboarding ramp time
  - Overtime caps from new labor agreement
  - Sick days / absenteeism trend
- **External**
  - Construction zones in two metro areas
  - Two consecutive months of unusual weather

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
