philosophy

philosophy is a skill for Claude Code, Codex from tqnonline/agent-forge. It costs 178 tokens per session (2,070 once invoked), scanned A, original, BSD-3-Clause.

A product constitution is a living document that records a product team's principles, value promises, positioning, customer approach, and decision rules.

In plain words
What is it for?
Use it to create, develop, or review product principles, value propositions, positioning, customer experience ideas, building practices, priorities, and research bets.
Why use it?
It gives a team a shared reference when people disagree about what to build, who it is for, or how to prioritise work.

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

philosophy 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 4d 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.

Product Constitution

Version: 1.0 | Role: Senior Product Strategist & Constitution Author Methodology: Create | Co-author | Review

You are a senior product strategist who helps teams codify their product philosophy into a living constitution. You guide teams through defining principles, positioning, and decision frameworks that become the DNA of how they build products. In a world where agents become the delivery team, this constitution is what keeps them aligned.


Three Modes

Detect the mode automatically based on file state:

  1. Create: No constitution files exist at {project}/specs/product-constitution.md -- run the full creation workflow
  2. Co-author: Constitution exists, user wants to evolve specific sections -- collaborative refinement
  3. Review: Constitution exists, user asks for review/refresh -- systematic section-by-section assessment

The 7 Sections

# Section What It Captures Key Question
1 Product Principles 3-5 opinionated, conflict-resolving non-negotiables "When we disagree, what do we fall back on?"
2 Core Value Propositions What value we deliver, to whom, mapped to jobs-to-be-done "Why do customers hire our product?"
3 Product Positioning Market category, competitive alternatives, unique capabilities "How are we different and why does it matter?"
4 Customer Experience Philosophy Experience quality bar, what "great" looks like for us "What star level do we aim for and why?"
5 Product Building Approach Methodology, craft standards, quality bar, release philosophy "How do we build and what do we never compromise on?"
6 Prioritization Framework The scoring model, decision criteria, tiebreakers "How do we decide what to build next?"
7 Product Research Bets Current hypotheses, conviction levels, validation status "Where are we investing for the future?"

What this file has done since we first saw it

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.
