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 | $0.01355 | $0.01355 |
| Opus 5 | $0.00678 | $0.00678 |
| Sonnet 5 | $0.00271 | $0.00271 |
| Haiku 4.5 | $0.00136 | $0.00136 |
Grade A, and why
greywater-recycling-constructed-wetland-agent-skill CLAUDE.md 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 11d 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.

CLAUDE.md — Skill 184: greywater-recycling-constructed-wetland
Skill Identity
- Skill Name:
greywater-recycling-constructed-wetland - Tagline: Greywater Treatment to Irrigation-Grade via Constructed Wetlands (Microbial Safety) — On-Site Greywater Treatment & Constructed Wetland Engineering analysis & decision-support harness.
- Current Phase: Phase 0 — Architecture & Research
- Folder:
D:\972026\184-greywater-recycling-constructed-wetland\
Problem This Skill Solves
This skill provides a structured, evidence-backed analytical workflow for On-Site Greywater Treatment & Constructed Wetland Engineering. It gathers authoritative real-time and reference data, applies recognized domain methods, cross-references academic research, and delivers actionable outputs that are fully evidenced, risk/limitation-disclosed, and traceable to authoritative sources — continuously self-improving through an automated knowledge crawl pipeline.
Harness Flow Summary
/greywater-recycling-constructed-wetland invoked
│
├─ Step 1: sub-gather-requirements → Clarify the object of analysis, constraints, timeframe, available inputs, target audience, and language before any data fetching.
├─ Step 2: sub-evidence-collector → Fetch authoritative real-time and reference data for the object: current status/parameters, authoritative documents/standards, and recent developments from domain and academic sources.
├─ Step 3: sub-core-analysis → Design a household greywater treatment system (constructed wetland + natural filtration) to produce irrigation-grade water meeting microbial safety standards.
├─ Step 4: sub-knowledge-updater → Query SECOND-KNOWLEDGE-BRAIN.md for authoritative academic and professional evidence; surface citations with tier labels and flag gaps for the crawl pipeline.
├─ Step 5: sub-advisor → Synthesize all prior analysis into a risk-disclosed conclusion with a full evidence chain and recommended actions.
└─ Step 6: main (quality gate) → verify evidence hierarchy, disclosure, output polish
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.

greywater-recycling-constructed-wetland-agent-skill CLAUDE.md is an instructions file published in the GitHub repository dungnotnull/greywater-recycling-constructed-wetland-agent-skill (5 stars, last pushed 1mo ago), licensed MIT. It adds 1,355 tokens to every session, about $0.0068 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 2026-08-31.
