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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 760 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- low Excessive Agency · line 63 Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.
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 | $0.00129 | $0.02865 |
| Opus 5.5 | $0.00052 | $0.01146 |
| Sonnet 5.5 | $0.00026 | $0.00573 |
| Haiku 4.5 | $0.00013 | $0.00286 |
Grade A, and why
stelow-product-evolutionary-principles 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.
How it starts
The opening of the file, as written. The whole thing — 506 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Evolutionary Product Thinking
A strategic thinking skill inspired by:
- evolutionary systems
- novelty search
- stepping-stones theory
- adaptive systems
- product ecosystems
- connection mapping
- exaptation
- emergent innovation
This skill helps teams:
- avoid premature convergence
- identify promising stepping-stones
- evaluate evolutionary potential
- explore non-obvious product directions
- prioritize enabling capabilities
- think beyond rigid roadmap logic
- cultivate adaptability and resilience
This is NOT:
- a strict prioritization framework
- a deterministic roadmap generator
- a KPI optimization method
- a growth-at-all-costs system
It is:
- a strategic reflection lens
- an evolutionary exploration framework
- a discovery-oriented planning perspective
- a system for evaluating adaptability and optionality
Cross-Domain Adaptation
This skill is not limited to digital products.
The same evolutionary principles can be adapted to:
- careers and professional growth
- habits and personal development
- relationships and communities
- organizational design
- education and learning
- research and scientific exploration
- creativity and artistic practice
- life strategy and decision-making
To adapt the skill to another domain:
- reinterpret “features” as capabilities, behaviors, practices, or structures
- reinterpret “users” as participants, stakeholders, or agents
- reinterpret “ecosystem” as the surrounding social, organizational, biological, or environmental context
- reinterpret “fitness” as long-term adaptability, resilience, usefulness, meaning, or sustainability depending on the domain
Focus on:
- increasing optionality
- enabling emergence
- preserving diversity
- discovering stepping-stones
- avoiding premature convergence around rigid goals
Core Philosophy
Evolution is Discovery, Not Goal Execution
The central premise:
Great products and innovations often emerge indirectly.
Instead of:
- rigid optimization toward predefined objectives
- narrow feature planning
- excessive convergence
- deterministic roadmaps
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

stelow-product-evolutionary-principles is a skill published in the GitHub repository calionauta/stelow (14 stars, last pushed 9d ago), licensed MIT. It adds 129 tokens to every session and 2,865 once invoked, about $0.0005 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 2026-08-30.
