[Internal sub-skill of polylith-migrate-orchestrator. An agent skill from DavidVujic/python-polylith.

  • Works in 3 steps: Review the circular imports report → Resolve circular imports → Record resolved circular imports
  • SKILL.md covers Goal, Inputs, Steps and Output, plus 2 more sections
  • Calls git

What it does

Polylith Migrate Resolve Circular Imports is an agent skill from DavidVujic/python-polylith. [Internal sub-skill of polylith-migrate-orchestrator. Do not load directly — load polylith-migrate-orchestrator first, which drives all phases.] Resolve circular imports by updating imports in the new base location to avoid referencing the compatibility shim.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Tooling support for the Polylith Architecture in Python. The licence is MIT.

Example prompts

  • “/polylith-migrate-resolve-circular-imports”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Review the circular imports report
  2. Resolve circular imports
  3. Record resolved circular imports

What it can do on your machine

Read from SKILL.md and the folder at commit a7a80f2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Polylith Migrate Resolve Circular Imports loads about 676 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 216 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~676

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
[Internal sub-skill of `polylith-migrate-orchestrator`. Do not load directly — load `polylith-migrate-orchestrator` first, which drives all phases.] Resolve circular imports by updating imports in the new base location to avoid referencing the compatibility shim.

Skill: polylith-migrate-resolve-circular-imports

⛓ Conditional phase (4b). Runs only when SHIM_STRATEGY=shim (chosen in polylith-migrate-analyze-imports) and only if polylith-migrate-detect-circular-imports found cycles. Skipped on the shimless path. See the polylith-migrate-orchestrator workflow.

Goal

Resolve circular imports by updating imports in the new base location to avoid referencing the compatibility shim, ensuring a clean dependency graph.

Inputs

  • Project name (from migration/<project-name>/state.md)
  • Original namespace (from migration/<project-name>/state.md)
  • New namespace (from migration/<project-name>/state.md)
  • Circular imports report (from migration/<project-name>/circular_imports.md)

Steps

1. Review the circular imports report
  1. Review the circular imports report to identify all circular import chains.
2. Resolve circular imports
  1. For each circular import chain:
    • Update imports in the new base location (bases/${TARGET_TOP_NS}/${INITIAL_BASE_NAME}/) to avoid referencing the compatibility shim
    • Use direct imports from the new namespace instead
    • Consider using forward references or dependency injection where necessary

Example:

python
# Before (circular import with shim)
from myproject.core import MyClass

# After (direct import from new namespace)
from mynamespace.mybase.core import MyClass
3. Record resolved circular imports
  1. Record all resolved circular imports in migration/${PROJECT}/circular_imports_resolved.md.

Output

  • Updated files in the new base location
  • A report file: migration/<project-name>/circular_imports_resolved.md listing resolved circular imports

Verify

  1. Confirm that all circular imports listed in migration/<project-name>/circular_imports.md have been resolved.
  2. Verify that no circular imports remain by re-running the circular import detection.
  3. Ensure the codebase remains functional by running the test command from migration/<project-name>/state.md.

Commit

bash
git add bases/${TARGET_TOP_NS}/${INITIAL_BASE_NAME}/
git add migration/${PROJECT}/circular_imports_resolved.md
git commit -m "migrate(${PROJECT}): phase <N> — resolve-circular-imports"

<N> is this phase's number from the polylith-migrate-orchestrator table (the single source of truth) — do not hardcode it.
