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 | $0.00031 | $0.00746 |
| Opus 5 | $0.00015 | $0.00373 |
| Sonnet 5 | $0.00006 | $0.00149 |
| Haiku 4.5 | $0.00003 | $0.00075 |
Grade A, and why
defillama-openapi-skill 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 8d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DefiLlama Public API Skill
Use this skill to run DefiLlama public API operations through uxc + OpenAPI.
Reuse the uxc skill for shared execution, auth, and error-handling guidance.
Prerequisites
uxcis installed and available inPATH.- Network access to
https://api.llama.fi. - Access to the curated OpenAPI schema URL:
https://raw.githubusercontent.com/holon-run/uxc/main/skills/defillama-openapi-skill/references/defillama-public.openapi.json
Scope
This skill covers a public read-only analytics surface on api.llama.fi:
- protocol TVL list
- per-protocol detail
- chain overview reads
This skill does not cover:
- write operations or account management
- DefiLlama Pro key-in-path auth
- split-host public services such as
coins.llama.fiandyields.llama.fi - the full DefiLlama public API surface
Authentication
This public skill does not require authentication.
Core Workflow
-
Use the fixed link command by default:
command -v defillama-openapi-cli- If missing, create it:
uxc link defillama-openapi-cli https://api.llama.fi --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/defillama-openapi-skill/references/defillama-public.openapi.json defillama-openapi-cli -h
-
Inspect operation schema first:
defillama-openapi-cli get:/protocols -hdefillama-openapi-cli get:/protocol/{protocol} -hdefillama-openapi-cli get:/v2/chains -h
-
Prefer narrow read validation before broader reads:
defillama-openapi-cli get:/v2/chainsdefillama-openapi-cli get:/protocolsdefillama-openapi-cli get:/protocol/{protocol} protocol=aave
-
Execute with key/value parameters:
defillama-openapi-cli get:/protocol/{protocol} protocol=aavedefillama-openapi-cli get:/v2/chains
Operations
get:/protocolsget:/protocol/{protocol}get:/v2/chains
Guardrails
- Keep automation on the JSON output envelope; do not use
--text. - Parse stable fields first:
ok,kind,protocol,data,error. - Treat this v1 skill as read-only. Do not imply wallet, trading, or admin support.
- Public DefiLlama data is split across multiple hosts. This skill intentionally stays on
api.llama.fi; use the separate Pro skill when you need the unified Pro host. defillama-openapi-cli <operation> ...is equivalent touxc https://api.llama.fi --schema-url <defillama_openapi_schema> <operation> ....
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.

defillama-openapi-skill is a skill published in the GitHub repository holon-run/uxc (113 stars, last pushed 1mo ago), licensed MIT. It adds 31 tokens to every session and 746 once invoked, about $0.0002 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 2026-08-30.
