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.

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 | $0.00159 | $0.05680 |
| Opus 5.5 | $0.00064 | $0.02272 |
| Sonnet 5.5 | $0.00032 | $0.01136 |
| Haiku 4.5 | $0.00016 | $0.00568 |
Grade A, and why
orchestrations 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 today.
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.
This is a copy
100% identical to orchestrations — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use
Multi-phase work that chains several foundational skills against one or more MCP server projects. Typical triggers:
- "Build N new servers" / "scaffold and ship X, Y, Z" →
workflows/greenfield-build.md - "Update and release these servers" / "run maintenance and ship" →
workflows/maintenance-release.md - "QA / field-test / find-and-fix bugs in these servers" →
workflows/field-test-fix.md - "Fix these issues and ship" / handoff document with findings to act on →
workflows/fix-wrapup-release.md
Single-skill work — running just maintenance, just git-wrapup, just release-and-publish — invokes the foundational skill directly. Use this orchestrations skill when at least two phases need to chain.
Mental Model — Three Tiers
| Tier | Layer | Examples | Who reads it |
|---|---|---|---|
| 1 | Foundational task skills | git-wrapup, release-and-publish, maintenance, field-test, setup, design-mcp-server, polish-docs-meta, code-simplifier, add-tool, add-resource, add-service, add-test, etc. |
Orchestrator AND sub-agents (by direct path reference) |
| 2 | Orchestration workflows | The four files under workflows/ |
Orchestrator only |
| 3 | Router | This SKILL.md |
Orchestrator only |
Workflows in Tier 2 sequence Tier 1 skills with gates and verification. They never duplicate Tier 1 content — they direct to it. A workflow file says "Phase N: agent reads and runs framework-skills/git-wrapup/SKILL.md," not "here's how to wrap up a release."
The orchestrator is the agent driving the workflow — the one reading this SKILL.md. Sub-agents the orchestrator spawns receive prompts pointing at Tier 1 skills directly; they do not receive this skill or the workflow file. That boundary prevents recursive sub-agent spawning.
Pick a Workflow
Identify the workflow from user intent first, then sanity-check against project state if intent is ambiguous.
| User intent / state signal | Workflow |
|---|---|
New scaffold(s) from bunx @cyanheads/mcp-ts-core init, no implementation yet (echo definitions still present, no released changelog) |
workflows/greenfield-build.md |
Existing server(s), bun outdated shows updates, want to land them and ship |
workflows/maintenance-release.md |
| Existing server(s), want to find bugs via live testing and fix them, optionally ship | workflows/field-test-fix.md |
| Existing server(s) with known issues (GH issues, handoff document, observed gap), want to fix and ship | workflows/fix-wrapup-release.md |
What ships with it
4 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.
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.

orchestrations is a skill published in the GitHub repository cyanheads/calculator-mcp-server (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 159 tokens to every session and 5,680 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to orchestrations, differing in 2 lines, and is treated as a copy.

lain
Structural code intelligence for AI coding agents.

plan
Design an implementation plan before writing code — where the change lands, what it will touch, what could break, and the steps in order. Use when asked to plan a feature, scope a change, or figure out how to approach an edit before making it. To assess a change that already exists (a diff, refactor, or rename), use…
