Propose Aip

Author and propose a new AIP

Use this skill when the user asks to draft, propose, or standardise something agent-related — a file format, a runtime primitive, a governance rule, a shared building block. The skill produces a complete AIP draft: the spec doc, the canonical schema, an adapter guide, examples, and at least one authoring SKILL.md.

The lifecycle, required frontmatter, and submission process come from AIP-1. The body template comes from AIP-2. This skill is the agent-driven projection of both — it walks you through them step by step.

When to use

• "Write up an AIP for declaring agent personalities."
• "I have a pattern that's been re-implemented three times — turn it into a shared spec."
• "Standardise the way operators record decisions, propose an AIP."

When NOT to use

• The user wants to amend an existing AIP — that's a spec edit, not a new AIP. Edit the .mdx directly and bump the version semantics there.
• The proposal is implementation-specific (one host, one vendor) — AIPs are vendor-neutral by AIP-1 rule. If it doesn't generalise to a second implementation, it's not an AIP.
• The user wants a tutorial / blog post / internal doc — those go somewhere else.

Process

Follow these steps in order. Steps 1–5 produce the AIP draft; steps 6–8 produce the resources folder; step 9 wires the new doc into the index.

1. Pick the number

• Look at the highest existing AIP number in meta.json (search for the AIP index page).
• Reserve the next integer. AIP numbers are immutable once a draft is committed — pick once, never renumber.
• If the AIP is a schema-block (composable building block, not a manifest users author — like AIP-16 IO.md, AIP-17 RUNTIME.md), flag it in the abstract.

2. Decide the type

3. Write the frontmatter

Mirror the template in AIP-2:

---
title: "AIP-NN: <NAME>.md — <one-line purpose>"
description: <one-paragraph abstract for search + indices>
aip: NN
status: Draft
type: Schema | Core | Meta | Informational
created: <ISO date>
author: <Name> <email>
requires: [<aip-numbers this depends on>]
resources: ./resources/aip-NN/draft
discussions-to: https://github.com/agentproto/agentproto/discussions/NN
---

4. Write the body

Required sections (in order):

## Abstract

One paragraph: what does this AIP standardise, and why.

## Motivation

Why this can't live as a vendor-specific feature. Name the duplication / drift /
security concern that prompted the proposal.

## Design principles

3–7 numbered principles. Keep them short — two sentences max each.

## Specification

The normative content. Tables, schemas, signatures. Use MUST / MAY / SHOULD per
RFC 2119.

## The `defineXxx` standard signature

If the AIP defines a manifest format that runs code, declare the canonical
entry-point function name + signature. Bullet-point the conformance rules.

## Compatibility

What changes when this is adopted. Migration guidance.

## Security considerations

Threat model + mitigations specific to this AIP. Don't punt.

## Open questions

Anything you couldn't settle in the first draft. Resolve over time in
`discussions-to:`.

## See also

Cross-links to related AIPs.

Optional but encouraged:

• ## Adjacency to other specs — name MCP / OpenAPI / JSON Schema / similar where this AIP overlaps.
• ## Reference Implementation — point to a real host that ships this AIP, when one exists.

5. Drop the v1.x markers

While the AIP is Draft, don't put inline version markers ("v1.1", "v2.0") in field tables or section headers. Once shipped under Final, future amendments live as separate AIPs OR get a clearly-marked "## Changes since X" section. Drafts are fluid; versioning them in-line is noise.

6. Generate the schema (if Type = Schema)

Author resources/aip-NN/draft/<NAME>.schema.json:

• JSON Schema Draft 2020-12.
• $id = https://agentproto.dev/schemas/aip-NN/<NAME>.schema.json.
• Strict additionalProperties: false on the top-level object and on every concrete sub-shape (helps catch field-name typos).
• $ref into AIP-16 (IO blocks) and AIP-17 (runtime block) when your AIP defines a manifest type that imports them. Don't redeclare those blocks.

7. Write the ADAPTER.md

Host-implementer guide. Cover:

• Required behaviour for the manifest's standard signature.
• Lifecycle around the body (parse → validate → run → cleanup).
• Multi-language naming conventions for the standard signature.
• Registration test — what validate(manifestPath) checks.
• What this guide does NOT cover (other AIPs handle).

8. Write at least one SKILL.md

Pick a verb that names the most common author task:

• author-<thing> for AIPs whose users write a <NAME>.md file (TOOL.md → author-tool, WORKFLOW.md → author-workflow).
• use-<block> for schema-block AIPs that other AIPs consume (IO.md → use-io-blocks, RUNTIME.md → use-runtime-block).
• <verb>-<noun> for everything else (curate-wiki, propose-aip, configure-governance).

Mirror the AIP-3 skill format: frontmatter (schema: skills/v1), When to use / When NOT, Process steps, Output, See also.

Each SKILL.md goes in resources/aip-NN/draft/skills/<verb>-<noun>/SKILL.md.

9. Wire into the index

Three places to update:

1. meta.json — append "aip-NN" to the pages array.
2. index.mdx — add a row to the AIPs table:

   | [AIP-NN](/docs/aip-NN) | <NAME>.md — <one-line purpose> | Schema | Draft |
   

3. The Categories list line (Schema — file formats … (AIPs 3–5, 10–NN)) — extend the upper bound.

10. Submit for discussion

Open the GitHub discussion the frontmatter discussions-to: points to. Cross-link from any existing AIPs that reference yours (via requires: or "See also") so reviewers see the dependency graph.

Output

A new AIP draft consisting of:

1. aip-NN.mdx with full frontmatter + body covering the required sections.
2. resources/aip-NN/draft/<NAME>.schema.json (Schema type only).
3. resources/aip-NN/draft/ADAPTER.md (host implementer's guide).
4. resources/aip-NN/draft/EXAMPLES.md (3+ reference manifests, if applicable).
5. resources/aip-NN/draft/skills/<verb>-<noun>/SKILL.md (at least one).
6. meta.json + index.mdx updated.
7. A GitHub discussion thread linked in discussions-to:.
