At a glance

Shape of a story blueprint, the technical plan an orchestrator executes.

  • Reading a blueprint artifact
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Blueprint Format is an agent skill from Inebrio/Routerly. Shape of a story blueprint, the technical plan an orchestrator executes. Use when writing or reading a blueprint artifact.

Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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

  • Reading a blueprint artifact

Example prompts

  • “/blueprint-format”

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 (its code samples are markdown).

    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

Blueprint Format loads about 581 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 111 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~581

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.

description
Shape of a story blueprint, the technical plan an orchestrator executes. Use when writing or reading a blueprint artifact.

Blueprint format

One file per story: <specs-root>/<feature>/02-blueprint/<story-id>.md.

markdown
# <story-id> — Blueprint

## Approach
The chosen shape in one paragraph, and the alternative you rejected with the
reason. No restatement of the why: that is closed in the analysis.

## Data model
What is stored, in what shape, what changes, what migrates. "Nothing" is a
valid and welcome answer.

## Files
| Path | New or changed | Responsibility |

## Contact points
Every interface between backend and frontend work, frozen:

| Contract | Shape | Consumed by |
Endpoint, method, request payload, response payload, status codes, error
shape, permission required. Field names exactly as they will ship.

## Tasks
| # | Task | Surface | Depends on | Done when |
One row is one engineer dispatch. Independently verifiable, but not
necessarily one file or one step: group mechanical, same-surface steps with
no cross-cutting contract (a config edit, a single-file addition, a small
parity check) into one row rather than splitting by step. "Done when" ties
back to the story's acceptance criteria by id, and may list several ids when
a row bundles several steps.

## Validation setup
- Start command: the exact command, run from the worktree root.
- Environment: what to source, which ports, which isolated runtime.
- Credentials and seed data the validator needs.
- How to reach each surface the story touches.

## Risks
What this plan could get wrong, and the cheapest way to find out early.

Rules

  • Written against the code you actually read, never against how projects usually look.
  • Every contact point is frozen here or the orchestrator will have to invent it. Ambiguity at this line is the most expensive kind.
  • The start command is executed verbatim by the validator. A wrong one invalidates the whole validation, so verify it before writing it down.
  • Plan the smallest thing that satisfies the story. No extension points nobody asked for, no abstraction with a single implementation.
  • If the story cannot be built as written, state the conflict at the top with options and consequences, then plan what can be built.
