arnesto: Skill for Claude Code

.agents/skills/positioning-canvas/SKILL.md

positioning-canvas is a skill for Claude Code, Codex from saski/arnesto. It costs 81 tokens per session (672 once invoked), scanned A, a copy of positioning-canvas, Unlicense.

A product-positioning framework for explaining who a product is for, what alternatives it competes with, and why customers should choose it. Positioning is the strategic description of a product's distinct value, not just a tagline.

In plain words
What is it for?
Use it to define target customers, competitive alternatives, differentiated value, and a clear market category.
Why use it?
It helps when customers, sales, marketing, and product teams describe the product differently or when prospects do not quickly understand its value.

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

positioning-canvas 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 3d 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.

Origin

Domain Context

This skill implements a proven product management framework. The approach combines best practices from industry leaders and is designed for practical application in day-to-day PM work.

Input Requirements

  • Context about your product, feature, or problem
  • Relevant data, research, or constraints (recommended but optional)
  • Clear articulation of what you're trying to achieve

Positioning Canvas

What It Is

Positioning defines how your product is the best in the world at delivering some value that a well-defined set of customers care a lot about.

The core insight: Positioning is not messaging. It's not your tagline. It's the fundamental strategic decision about how you win in the market — what you compete against, how you're different, what value only you can deliver, and who cares most about that value.

When positioning is weak:

  • Prospects don't understand what you are on first contact
  • Sales calls require 3+ meetings before "the light comes on"
  • You win deals but customers churn because expectations didn't match reality
  • Different teams (sales, marketing, product) tell different stories

When positioning is strong:

  • It feels obvious — "of course that's what it is"
  • Qualified prospects immediately understand why they should care
  • Your differentiated value is clear against alternatives
  • Everyone in the company tells the same story

When to Use It

Use Positioning Canvas when you need to:

  • Define or refine how you compete — who are the real alternatives?
  • Articulate differentiated value — why pick you over everything else?
  • Identify your best-fit customers — who cares most about your value?
  • Choose or validate your market category — what context makes your value obvious?
  • Align your team — get sales, marketing, product, and leadership on the same page
  • Build a sales pitch — translate positioning into a story that wins deals
  • Reposition after market changes — your product evolved, competition shifted, or customers changed

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.
