add-provider

add-provider is a skill for Claude Code, Codex from agentconfig/agentconfig.org. It costs 55 tokens per session (1,862 once invoked), scanned A, original, ISC.

A procedure for adding an AI coding assistant to agentconfig.org's comparison system, including its types, provider data, interface, tests, documentation, and generated files.

In plain words
What is it for?
Use it when integrating an assistant such as Cursor, Claude Desktop, or another alternative, including documenting how it supports the site's AI primitives.
Why use it?
It coordinates the many parts that must change when a new provider is added, helping the comparison stay complete and consistent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-provider scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Add Provider

Add a new AI coding assistant provider to agentconfig.org's provider comparison system.

Overview

Adding a provider requires coordinated work across 6 parallel work streams:

Stream Work Duration Dependencies
1. Type System Add provider to union types 2-4 hrs None
2. Data Layer Add implementations for all 13 primitives 4-6 hrs Stream 1
3. UI Components Update comparison table 4-8 hrs Streams 1-2
4. Testing Update E2E tests 3-4 hrs Stream 3
5. App Integration Update site copy & docs 1-2 hrs Streams 1-3
6. LLMs Generation Regenerate machine-readable files 1-2 hrs All streams

Total effort: ~2-3 hours with parallelization

When to Use

Use this skill when:

  • Integrating a new coding assistant (Cursor, Claude Desktop, Zed with AI, etc.)
  • Expanding provider support beyond current offerings
  • The provider implements most of the 13 AI primitives
  • You want comprehensive comparison data visible to users and AI agents

Prerequisites

Before starting, gather:

  • Provider capability audit - Which of the 13 primitives does the provider support?
  • File path documentation - Where do config files go (global vs project)?
  • Support levels - primitives.ts and comparison.ts share one SupportLevel type: full (native), partial (workarounds), diy (custom setup or not achievable) — one vocabulary, no separate none value

The 13 Primitives

Every provider must map to all 13 primitives across the 8 layers below (layers are not 1:1 with primitives — Instructions has three, Memory & State currently has none); see categories in site/src/data/primitives.ts for the full layer list and scopeModel for the separate where-it-applies vocabulary — scopes are not primitives:

Layer Primitives
Instructions Persistent Instructions, User Scope Instructions, Directory / Path Scope Instructions
Procedures Skills / Workflows, Slash Commands
Tools & Context Tool Integrations (MCP)
Delegation Agent Mode, Custom Agents
Control & Approval Permissions & Guardrails, Lifecycle Hooks, Runtime Sandbox
Memory & State (reserved — no primitive is modeled here yet; do not add one without genuinely distinct memory/state semantics)
Distribution Configuration Distribution
Verification & Observability Verification / Evals

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

add-provider is a skill published in the GitHub repository agentconfig/agentconfig.org (8 stars, last pushed 7d ago), licensed ISC. It adds 55 tokens to every session and 1,862 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
