What it does
Interface Contracts is an agent skill from Inebrio/Routerly. How to freeze and arbitrate the interface between parallel implementers. Use when coordinating backend and frontend work on the same story.
Its SKILL.md is about 570 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 Legal & Compliance. The repository describes itself as: Self-hosted LLM gateway that routes requests across AI providers (OpenAI, Anthropic, Gemini, Mistral, Ollama) using intelligent multi-policy scoring — including an LLM-native… The licence is AGPL-3.0.
When your agent uses it
- Coordinating backend and frontend work on the same story
Example prompts
- “/interface-contracts”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- The frozen contract wins. Neither side changes it unilaterally.
- If the contract is genuinely wrong, decide the new shape, write it down,
- Prefer the change that keeps the consumer honest: an optional field is
What it can do on your machine
Read from SKILL.md and the folder at commit bcf58f1. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Interface Contracts loads about 572 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 353 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.

- How to freeze and arbitrate the interface between parallel implementers. Use when coordinating backend and frontend work on the same story.
Interface contracts
Two implementers working at once fail in exactly one way: each assumes a different shape at the line where their work meets. Freezing that line before either starts is the whole job.
What a contact point is
Anywhere data crosses between the people working in parallel: an HTTP endpoint, a shared type, a config key, a file format, an event, an exit code, an error string a caller matches on.
Freezing one
A contract is frozen when both sides could implement against it without asking a question. That means, for an endpoint:
- method and path, exactly as it will ship
- request shape, with field names and types
- response shape for success, with field names and types
- status codes, including the failure ones
- error body shape
- permission or auth required
- pagination, ordering, and what an empty result looks like
Vague is worse than wrong. returns the list of items is not a contract:
one side ships {items: []}, the other reads [], and nobody finds out
until integration.
Shared types are the cheapest contract in a typed monorepo: define the type once in the shared package, have both sides import it, and the compiler enforces what a document cannot.

Sequencing
Give the type or interface definition to one side as its first task and let the other consume it. When both must start now, write the contract into the blueprint and hold both to it verbatim.
Arbitration
When the two sides disagree mid-flight:
- The frozen contract wins. Neither side changes it unilaterally.
- If the contract is genuinely wrong, decide the new shape, write it down, and tell both sides in the same message. Never let two versions coexist.
- Prefer the change that keeps the consumer honest: an optional field is cheaper than a renamed one, a new endpoint is cheaper than a repurposed one.
What is not yours to decide
- A gap in the plan goes back to whoever wrote the plan.
- A conflict with another story in flight goes up to whoever owns the dependency graph.
- A change to what the story asks for is not negotiable at this level.
