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.

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 | $0.00040 | $0.00882 |
| Opus 5 | $0.00020 | $0.00441 |
| Sonnet 5 | $0.00008 | $0.00176 |
| Haiku 4.5 | $0.00004 | $0.00088 |
Grade A, and why
token-economics 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 8d 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
token-economics
Tokens are not only a billing unit. They are an operational energy budget.
In this system:
- tokens spent = energy consumed
- useful output = work extracted
- signal per token = efficiency
- throughput per watt / per dollar = system fitness
token-awareness asks "what is the minimum effective change?"
token-economics asks "what is the best return on energy for this workload?"
1) Core Questions
Before choosing an implementation path, model, or orchestration pattern, ask:
- What is the expected token burn for this task?
- How much of that burn produces useful signal instead of exploration noise?
- Can the same outcome be achieved with fewer reads, fewer hops, or a smaller model?
- What is the comparable performance per watt / per dollar across routes?
2) Energy Framing
Use these derived metrics:
energy_cost = total tokens consumed
useful_work = accepted decisions, code changes, validated conclusions
energy_efficiency = useful_work / energy_cost
throughput_per_watt = useful_work / wall_time / watts
throughput_per_dollar = useful_work / dollar_cost
If real watt telemetry is unavailable, use tokens as the normalized energy unit.
That still enables valid comparisons:
- route A vs route B
- model A vs model B
- single-agent vs multi-agent
- broad read vs grep + targeted read
3) Comparison Template
Option A: large-model, broad context read
- 12k input tokens
- 2 tool hops
- 1 answer
- low implementation risk
Option B: grep + targeted reads + smaller model
- 2.5k input tokens
- 4 tool hops
- 1 answer
- similar implementation risk
If output quality is comparable, B has much better energy efficiency.
4) What Usually Burns Energy
- broad exploratory reads without a concrete question
- repeated re-reading of the same files
- too many agent handoffs
- large-model use for narrow deterministic tasks
- verification that repeats the implementation worker's path instead of testing the result
- giant prompt blocks that carry stale context forward
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.

token-economics is a skill published in the GitHub repository LuuOW/meridian-mcp (0 stars, last pushed 2d ago), licensed MIT. It adds 40 tokens to every session and 882 once invoked, about $0.0002 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.
