Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.03761 |
| Opus 5.5 | $0.00033 | $0.01504 |
| Sonnet 5.5 | $0.00016 | $0.00752 |
| Haiku 4.5 | $0.00008 | $0.00376 |
Grade A, and why
product-life-cycle 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 252 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Read runtime and advisory rules before applying this skill. Other Foreman layers and the catalog are in ../../content/, relative to this SKILL.md.
Product Life Cycle
The BlackBerry was once the most coveted device in corporate America -- the "CrackBerry" that redefined mobile communication. The fax machine was, for two decades, as essential to business as the telephone. The Sony Walkman created the portable music category, sold 400 million units, and was rendered obsolete in under a decade. Every product, however dominant in its moment, follows a biological arc: birth, growth, maturity, and decline. Theodore Levitt formalised this observation in a 1965 Harvard Business Review article, and the Product Life Cycle (PLC) has since become one of the foundational frameworks of marketing and business strategy -- not because it predicts the future with precision, but because it forces the uncomfortable question every entrepreneur must eventually answer: what phase is your product in, and are you managing accordingly?
The framework's power lies in its strategic implications. The same product, in different phases, demands different pricing, different marketing, different competitive responses, and different levels of investment. Companies that manage a growth-phase product as if it were mature leave money on the table. Companies that manage a mature product as if it were still growing burn cash without return. And companies that refuse to acknowledge decline preside over slow organisational death.
The Framework
The Four Phases
Phase 1: Introduction
The product enters the market. Sales are low. Costs are high. Profit is negative or minimal. The customer base consists of innovators and early adopters who tolerate imperfection in exchange for novelty or functional advantage.
Characteristics:
- High unit cost due to low volume and manufacturing learning curve
- Heavy investment in education and awareness (the market does not yet understand the product)
- Limited or no competition (but watch for fast followers)
- Pricing strategy: either skimming (high price, early revenue capture) or penetration (low price, rapid adoption)
- Distribution is narrow; channels are being established
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.

product-life-cycle is a skill published in the GitHub repository fatihguner/foreman (63 stars, last pushed 1mo ago), licensed MIT. It adds 82 tokens to every session and 3,761 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
