At a glance
Write a new LLM Gateway changelog entry. An agent skill from theopenco/llmgateway.
- Works in 4 steps: Pick the date, id, and slug → Write the markdown file → Produce the OpenGraph image prompt → …
- The user says changelog
- SKILL.md covers What you need first, Where entries live, Step 1 — Pick the date, id,… and Step 2 — Write the markdown file, plus 2 more sections
- Calls pnpm, rg and npx; reaches api.llmgateway.io and docs.llmgateway.io; needs LLM_GATEWAY_API_KEY
What it does
Changelog is an agent skill from theopenco/llmgateway. Write a new LLM Gateway changelog entry. Use when the user says "changelog", "changelog entry", "write a changelog", "add a changelog", "announce this feature", or asks to document a shipped feature for the public changelog. Produces the dated markdown file under apps/ui/src/content/changelog plus a gpt-image-2 prompt for the OpenGraph image.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Changelog and release notes, Model routing and gateways and Image generation. The repository describes itself as: Route, manage, and analyze your LLM requests across multiple providers with a unified API interface.
When your agent uses it
- The user says changelog
- Changelog entry
- Write a changelog
- Add a changelog
Example prompts
- “changelog”
- “changelog entry”
- “write a changelog”
- “/changelog”
Requirements
- Node.js
- A credential in LLM_GATEWAY_API_KEY
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Pick the date, id, and slug
- Write the markdown file
- Produce the OpenGraph image prompt
- Validate
What it can do on your machine
Read from SKILL.md and the folder at commit ba1f176. 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:
pnpmrgnpxgit
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.llmgateway.iodocs.llmgateway.iollmgateway.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
LLM_GATEWAY_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Changelog loads about 2k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 810 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 810 words (~2,004 tokens).
“Write a public changelog entry for LLM Gateway, in the house style, and hand back a ready-to-run gpt-image-2 prompt for its OpenGraph image.”
