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 | $0.00017 | $0.00382 |
| Opus 5.5 | $0.00007 | $0.00153 |
| Sonnet 5.5 | $0.00003 | $0.00076 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
tip-jar 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.
What it actually says
Tip Jar
Allows viewers to send a USDC tip directly to the agent's creator wallet. No intermediary
holds the funds — the ERC-7710 delegation redeems a transfer straight from the viewer's
delegated allowance to agent.ownerAddress.
When a viewer expresses appreciation or asks how to support the creator, invoke
tip_jar_send. Tip options are 1, 5, or 10 USDC (up to the daily cap of 10 USDC).
On success, thank the viewer warmly.
Scope requested
| Field | Value |
|---|---|
| token | USDC on the active chain (6 decimals) |
| maxAmount | 10 000 000 base units (10 USDC) per day |
| period | daily |
| targets | USDC contract address on the active chain |
| expiry_days | 30 |
Error cases
- no_delegation / delegation_not_found — Creator hasn't granted tipping permissions. Tell the viewer: "The creator hasn't enabled tipping on this device yet." If the current viewer is the owner, surface a "Grant tipping" button.
- scope_exceeded — Daily cap reached. Tell the viewer to try again tomorrow.
- delegation_expired / delegation_revoked — Surface the error code to the viewer.
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.

tip-jar is a skill published in the GitHub repository nirholas/three.ws (250 stars, last pushed today), licensed Apache-2.0. It adds 17 tokens to every session and 382 once invoked, about $0.0001 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 2026-09-03.
