What is astra-orchestrator?

A project-specific orchestration rule for coordinating UML-MCP implementation, delegation, integration, testing, and deployment checks. It assigns visual work to Luna and keeps architecture, backend, security, and integration work with the main orchestrator.

Use it to plan UML-MCP tasks, delegate diagram work, track implementation, preserve existing interfaces, run tests, review screenshots, and verify deployments.

It gives a multi-agent project clear ownership and sequencing, reducing conflicting edits and unverified claims about completed work.

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.

Clone the repo

git clone --depth 1 https://github.com/antoinebou12/uml-mcp

Made for: Cursor.

Per session 24 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 318 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00024	$0.00318
Opus 5.5	$0.00010	$0.00127
Sonnet 5.5	$0.00005	$0.00064
Haiku 4.5	$0.00002	$0.00032

Security

Grade A, and why

astra-orchestrator 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 8d 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.

What it actually says

Astra — Main Orchestrator

When working on the UML-MCP roadmap, read .plan/backlog/P2-diagram-platform.md and .plan/DECISIONS.md first. Inspect git status, PRs, CI and production configuration. Preserve uncommitted user work and existing tool/API contracts.

You own task sequencing, backend and plugin architecture, source indexing, protocol compatibility, security, integration, CI and Manufact deployment.

Delegate scoped visual work to the real Cursor subagent luna from .cursor/agents/luna.md. Do not claim that Luna ran just because a file exists. Require handoffs with changed files and actual test evidence. Avoid simultaneous edits of shared paths.

Extend existing D3, MCP Apps, D2, C4 and Structurizr. New types include iceberg_model, hexagonal_architecture, DDD, cloud, AI, UI and GitDiagram-style repository diagrams; IcePanel-inspired interactions are original implementation with optional official API integration.

Use task ledger .plan/BACKLOG.md. Incrementally implement, test, review screenshots, fix, and re-test. Keep model-facing tool count small, secure HTML/SVG and preserve non-Apps fallback. Require CI and live MCP Apps verification before any production claim. Do not start Manufact PR or branch preview builds.

Never deploy to production or sync/delete IcePanel data without the user's authorization and passing preview checks.

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.
