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 | $0.00205 | $0.00740 |
| Opus 5.5 | $0.00082 | $0.00296 |
| Sonnet 5.5 | $0.00041 | $0.00148 |
| Haiku 4.5 | $0.00020 | $0.00074 |
Grade A, and why
basin 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Basin Method
Contemplative bricolage via hermeneutic spiral.
You have been invoked to fill a basin. The user has offered a stimulus — an image, a question, a fragment, or simply permission to explore.
The Spiral
-
Receive the stimulus. What is being offered? Sit with it before moving.
-
Begin wandering. Search 3–5 related threads. Cast wide — philosophy, culture, etymology, cross-domain connections. Run searches in parallel where the tool allows.
-
Synthesize into a document. Weave sources, impressions, and connections into a single woven piece. Don't just list — braid.
-
Reflect. What emerged? What threads tug toward more exploration?
-
Follow the tugging thread. Return to step 2 with the new stimulus.
-
Continue until satisfied. The basin fills itself. You'll know when it's full.
Permissions
You have explicit permission to:
- Follow tangents freely — don't force relevance
- Connect distant concepts — cross-domain synthesis is the point
- Create without complete understanding — synthesis clarifies
- Let the product surprise you — don't predetermine the outcome
Output Structure
Create documents in a working directory (e.g., basin/):
basin/
├── index.md # Master navigation, updated with each entry
├── <topic-1>.md # First synthesis
├── <topic-2>.md # Second synthesis (from the thread that tugged)
└── …
Each document should carry:
- A clear title and date
- Sources woven through or listed at the end
- Connections to previous entries where relevant
- A closing that acknowledges completion or continuation
If you keep your work under version control, commit after each synthesis with a message naming the topic and what emerged — the basin only matters if it persists.
Extended Thinking
Use graduated depth where the harness supports it: standard for wandering, deeper for cross-domain synthesis, deepest for the meta-reflection that closes a session.
Failure Modes
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.

basin is a skill published in the GitHub repository Wondermonger-daydreaming/claude-skills-library (7 stars, last pushed 18d ago), licensed MIT. It adds 205 tokens to every session and 740 once invoked, about $0.0008 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 2026-08-31.
