sagu-plugins AGENTS.md

Project instructions for maintaining Sagu plugins, which are add-ons distributed to several coding-agent clients. They require configuration changes to be made in one source file and then used to generate manifests and installation files.

In plain words
What is it for?
Use them when adding a client, changing plugin configuration, regenerating distribution files, or verifying Sagu plugin packages.
Why use it?
They prevent generated files from drifting out of sync and make sure updates work across Codex, Claude Code, Cursor, and the plugin registry.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

sagu-plugins AGENTS.md 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sagu plugins — agent guide

Public distribution repo for Sagu: the sagu-dispatch and sagu-artifact skills + plugin manifests for Cursor, Codex, and Claude Code, plus .mcp.json and the MCP Registry server.json. Installable via npx skills add creative-int/sagu-plugins and the three client plugin marketplaces.

The one rule: generate, don't hand-edit

sagu.config.ts is the single source of truth. Every manifest, .mcp.json, server.json, and the README install block are emitted from it by tooling/generate.ts. Edit the config, then:

pnpm generate     # rewrite all generated files
pnpm verify       # check:generated (drift) + typecheck + MCP reachability smoke

Never hand-edit the generated files (.mcp.json, .claude-plugin/*, .codex-plugin/*, .cursor-plugin/*, server.json, the README AUTO-GENERATED block). CI runs check:generated and fails on drift.

To add a client

Add its install steps to installClients in tooling/generate.ts and, if it needs a manifest, add the manifest builder to the files map. Regenerate.

Scope

  • v0: two skills (sagu-dispatch, sagu-artifact) + 3 client manifests + .mcp.json + server.json, generated.
  • v0.2 (deferred): optional stop hooks / knowledge-graph guardrails.

The MCP tool surface is hosted by the Sagu MCP server:

  • packages/mcp — local stdio server (npx -y @sagu/mcp, RADAR_API_KEY).
  • apps/mcp — remote Streamable HTTP server (https://sagu-mcp.luke-nittmann.workers.dev/mcp).

Keep the agent-facing tool surface lean so it does not bloat context.

Platform posture

Tooling-only companion repo; no product runtime surface.

Companion plugin profile

This repo intentionally uses the agent-plugin-companion profile rather than the full app-family turborepo profile. It is a public agent-facing distribution repo for Sagu, so it owns generated plugin manifests, skills, MCP metadata, and install documentation — not product runtime surfaces.

Required root contract for this profile:

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.
