What it does
Adapter Author is an agent skill from DefiLlama/DefiLlama-Adapters. Validates whether a DefiLlama request belongs in DefiLlama-Adapters, then helps coding agents create and validate TVL adapters when it does. Use when a user wants to add a new DefiLlama TVL protocol listing, check repo fit, create or fix a TVL adapter, choose adapter helpers or registries, run node test.js, prepare PR metadata, or decide whether they should instead use DefiLlama/dimension-adapters or send a mail
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/adapter-patterns.md`, `references/protocol-intake.md` and `references/validation-and-pr.md`).
When your agent uses it
- A user wants to add a new DefiLlama TVL protocol listing
- Fix a TVL adapter
- Choose adapter helpers
- Run node test.js
Example prompts
- “Use the adapter-author skill to validate whether a DefiLlama request belongs in DefiLlama-Adapters, then helps coding agents create and validate TVL…”
- “/adapter-author”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Initial intake
- Repository-fit gate (required before editing)
- Workflow
What it can do on your machine
Read from SKILL.md and the folder at commit 3b0779f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Adapter Author loads about 1.4k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 109 tokens; SKILL.md has 726 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 726 words (~1,439 tokens).
“Use this skill to help a protocol developer add or inspect a DefiLlama TVL adapter using repo-native patterns. The primary use case is creating new TVL adapters; narrow fixes to existing adapters are also supported when the user asks.”
