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 | $0.00080 | $0.01994 |
| Opus 5 | $0.00040 | $0.00997 |
| Sonnet 5 | $0.00016 | $0.00399 |
| Haiku 4.5 | $0.00008 | $0.00199 |
Grade A, and why
s4h-evolution-niche 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 9d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Evolution: Niche
Georgy Gause's competitive exclusion principle, derived from experiments with paramecia in 1934, established one of ecology's foundational rules: two species competing for the same limiting resource in exactly the same way cannot stably coexist. One will outcompete the other and drive it to extinction — or one must shift to a different resource, time, place, or method. The principle is both a constraint and an invitation: coexistence requires differentiation.
The concept of the ecological niche — formalised by G. Evelyn Hutchinson as an n-dimensional hypervolume in which a species can maintain a viable population — gives the principle practical teeth. Every dimension of the environment that a species uses or is affected by defines one axis of its niche. Species can coexist when their niches overlap little enough on at least one critical axis. The axes are the dimensions of differentiation: what resource is used, when, where, and how.
This tool applies niche theory to competitive strategy. It identifies the dimensions along which players in a system compete, maps the niche each occupies, measures overlap, and identifies where differentiation creates space for coexistence or where displacement is the likely outcome. Stuart Kauffman's work on adjacent possibles adds a further dimension: the unoccupied niches that exist at the edge of current competition, waiting to be colonised by sufficiently novel variants.
Your Process
Step 1: Define the Competitive Space Identify who is competing in this system. List all meaningful players — current competitors, potential entrants, substitute strategies. Then name the resources or outcomes they are competing for: what is the limiting factor that determines fitness? In ecology, this might be food, territory, nesting sites; in business, it might be customer attention, talent, regulatory capacity, margin, or a specific buyer segment.
Framing check: Confirm the competitive arena before continuing. State the players, the limiting resource, and the time frame in one sentence, then use AskUserQuestion:
- Question: "I'm reading this as: [one sentence naming who is competing, for what limiting resource, and over what time frame]. Is that right?"
- Header: "Framing"
- Options:
- Yes — proceed — framing is correct
- Adjust — one element is off; user will correct it before you continue
- Reframe — different situation than read; incorporate the correction before proceeding
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.

s4h-evolution-niche is a skill published in the GitHub repository human-avatar/skills-for-humanity (223 stars, last pushed 1mo ago), licensed MIT. It adds 80 tokens to every session and 1,994 once invoked, about $0.0004 per session on Opus 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 2026-09-03.
