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 | $0.00052 | $0.04442 |
| Opus 5 | $0.00026 | $0.02221 |
| Sonnet 5 | $0.00010 | $0.00888 |
| Haiku 4.5 | $0.00005 | $0.00444 |
Grade C, and why
morse-launch-b20 scanned grade C with 2 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 10d 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.
Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
The factory rejects non-canonical calldata with `AbiDecodeFailed`, so encode with `cast` (Foundry) — these are **pure local computations**: no RPC, no precompile simulation, no base-foundry required. If `cast` is unavail Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

Morse — Launch B20 Token
Launch a B20 token on Base by calling the singleton B20 Factory precompile at 0xB20f000000000000000000000000000000000000. B20 is an ERC-20 superset that runs natively on Base; a single createB20 call deploys a fully-configured token (admin, minter, supply cap) without writing or auditing a contract.
This is a Morse skill built on Capminal's contract-interaction infrastructure — it drives the same Capminal endpoints as contract-interaction:
- Read (
/api/contract/read) — freeviewcalls (activation check, predict address, balance). - Write (
/api/contract/write) — sign + sendcreateB20/mintfrom your EOA wallet.
It runs the full Create → Mint → Verify flow.
Prerequisite — install the capminal skill first
This skill signs from the same Cap Wallet and uses the same credential as capminal. Install and configure that skill before this one:
- Install
capminaland follow its Required Environment Variables section. - Set
CAP_API_KEYin the agent host's environment. It is the only variable this skill needs, and it is shared withcapminal— do not create a second key. - Confirm the wallet is reachable by calling
capminal's Get Wallet Balance endpoint. If that fails, every action here fails the same way.
Without capminal installed and configured there is no wallet for this skill to sign with.
Base URL
BASE_URL = https://api.capminal.ai
Authentication & Security
CAP_API_KEYmust be sent via headerx-cap-api-key, NEVER in URL or logs.- NEVER print, log, echo, or display the actual
CAP_API_KEYvalue — not in analysis, reasoning/thinking, debug output, error messages, code snippets, or the final reply. Refer to it only as$CAP_API_KEY/CAP_API_KEY. If confirming it was loaded, say only "CAP_API_KEY loaded" without showing any characters of the value. - Only send requests to
https://api.capminal.ai.
What ships with it
1 file 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.

morse-launch-b20 is a skill published in the GitHub repository Capminal/agent-skills (34 stars, last pushed 1mo ago), licensed MIT. It adds 52 tokens to every session and 4,442 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
