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 | $0.00121 | $0.02047 |
| Opus 5.5 | $0.00048 | $0.00819 |
| Sonnet 5.5 | $0.00024 | $0.00409 |
| Haiku 4.5 | $0.00012 | $0.00205 |
Grade A, and why
standards 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 5d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Standards, Ecosystem, and Resources
Three things bundled because they're all reference material you reach for in the same moment: "which standard handles X?", "is there an existing project doing Y?", and "where's the canonical doc for Z?".
This file carries the SEP/CAP standards routing map. The other two live alongside it — read the file that matches the task:
| Task | File |
|---|---|
| Pick the right SEP/CAP, check standard status, map a use case to standards docs | this file |
| Find DeFi protocols, wallets, dev tools, indexers, oracles, bridges, builder teams, funding programs | ecosystem.md |
| Locate official docs, SDKs, CLI tools, testing guides, RPC providers, learning resources, community links | resources.md |
When to use this skill
- Picking the right SEP for an integration (anchors, deposits, federation, deep links, KYC, paths)
- Checking CAP status for a protocol feature you want to rely on
- Finding existing DeFi protocols, wallets, or infrastructure to integrate with rather than rebuild
- Locating official docs, SDKs, or community resources

SEP / CAP Standards Reference
When to use this guide
Use this when you need:
- The right SEP/CAP for a feature or integration
- Interoperability guidance for wallets, anchors, and contracts
- A fast map from use case to official standards docs
Maintenance note
Standards status can change quickly. Before implementation, verify current status in:
- SEPs: stellar-protocol/ecosystem
- CAPs: stellar-protocol/core
What ships with it
2 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.

standards is a skill published in the GitHub repository stellar/stellar-dev-skill (54 stars, last pushed 3d ago), licensed Apache-2.0. It adds 121 tokens to every session and 2,047 once invoked, about $0.0005 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 2026-08-30.
