moving-packages

A set of rules for moving packages and correcting relative file paths after the move.

In plain words
What is it for?
Use it when relocating packages and updating paths in source files, tests, manifests, fixtures, and utilities.
Why use it?
It reduces broken imports and test or fixture references caused by a package changing directory depth.

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

moving-packages 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 2d 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.

Origin

This is a copy

100% identical to moving-packages — 0 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Moving Packages

When moving packages to new locations, you must update all relative paths that reference root-level files or other packages.

Relative Path Calculation

Key Principle: Count the directory depth from the package to the root, then use that many ../ segments.

Formula: Count the directory depth from package to root (note: numbered prefixes like 1-framework count as one directory):

  • From packages/1-framework/1-core/shared/plan/ to root = 5 levels up (../../../../../)
  • From packages/2-sql/3-tooling/emitter/ to root = 4 levels up (../../../../)
  • From packages/3-targets/6-adapters/postgres/ to root = 4 levels up (../../../../)
  • From packages/3-extensions/pgvector/ to root = 3 levels up (../../../)

Common Paths to Update

  1. Test files - Paths to other packages:
    • Extension pack manifests (e.g., packages/sql/runtime/adapters/postgres/packs/manifest.json)
    • Fixture paths
    • Import paths in test utilities

Examples

Moving from packages/ to test/

Before (from packages/integration-tests/test/):

const packs = loadExtensionPacks(join(__dirname, '../../sql/runtime/adapters/postgres'), []);
// Resolves to: packages/sql/runtime/adapters/postgres

After (from test/integration/test/):

const packs = loadExtensionPacks(join(__dirname, '../../../packages/3-targets/6-adapters/postgres'), []);
// Resolves to: packages/3-targets/6-adapters/postgres

Why? From test/integration/test/:

  • ../test/integration/
  • ../../test/
  • ../../../ → root
  • ../../../packages/3-targets/packages/3-targets/

Checklist When Moving Packages

  1. Update test files - Paths to other packages, fixtures, manifests
  2. Update pnpm-workspace.yaml - Add/remove package globs if needed
  3. Update architecture.config.json - Add/remove package entries
    • For multi-plane packages, add separate globs for each plane (see .cursor/rules/multi-plane-packages.mdc)
  4. Update tsconfig.base.json - Update project references
  5. Update dependency-cruiser.config.mjs - Update exclude patterns if needed
  6. Update CI workflows - Update any hardcoded paths
  7. Update documentation - READMEs, AGENTS.md, etc.
  8. Update relative paths in source files - Manifest paths, import paths, etc.

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.
