What it does

Polylith Migrate Distribute Wiring 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.] Distribute app-wiring code from the residual component into the appropriate bases and shared components.

Its SKILL.md is about 1k 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-distribute-wiring”

Workflow steps

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

  1. Read the Residual Component
  2. Identify the Split
  3. Extract Shared Helpers
  4. Move Composite Functions
  5. Update Tests
  6. Clean Up

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 Distribute Wiring loads about 1k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 467 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.] Distribute app-wiring code from the residual component into the appropriate bases and shared components.

Skill: polylith-migrate-distribute-wiring

Goal

Distribute app-wiring code from the residual component into the appropriate bases and shared components.

Inputs

From migration/<PROJECT>/state.md:

  • TARGET_TOP_NS
  • INITIAL_BASE_NAME
  • Verification commands.
  • Base names.

From migration/<PROJECT>/manifest.md:

  • Current module map, including what remains in the residual component.

All inputs from state.md are assumed to satisfy the validation rules in polylith-migrate-discover (### Validation rules). Validate before proceeding.

Steps

1. Read the Residual Component
  • List every public function remaining in the residual module.
  • Confirm it contains only app-wiring code.
2. Identify the Split
  • Trace callers of each function (use grep).
  • Group callers by base or runner script.
  • Map each function to its natural base:
Function PatternBelongs InRationale
init_consumer, close_consumerHandler/consumer baseKafka consumer lifecycle is handler-specific
init_jobJobs baseJob bootstrap is jobs-specific
init_api / app factoryAPI baseHTTP server setup is API-specific
3. Extract Shared Helpers
  • Identify shared init functions (e.g., init_logging, init_db).
  • Move shared helpers to a bootstrap component if needed.
4. Move Composite Functions
  • Move composite functions to their respective bases.
  • Update runner scripts to import from the base directly.
5. Update Tests
  • Update integration tests to monkeypatch the correct module.
6. Clean Up
  • Delete the residual component directory.
  • Update pyproject.toml to remove the residual brick.

Verify

  • RUN_TEST_CMD succeeds.
  • If set, RUN_LINT_CMD and RUN_TYPECHECK_CMD succeed.
  • Run POLY_CMD_PREFIX check to validate the workspace structure.
  • Run POLY_CMD_PREFIX sync to synchronize the [tool.polylith.bricks] table with actual imports.

Common failure modes

SymptomLikely causeRemediation
Two bases now import the same init_<x> function and the residual still existsStep 6 wasn't reached — the function moved into one base but the residual reference wasn't deleted.Confirm the residual is gone; if init_<x> is genuinely shared by 2+ bases, it belongs in a shared bootstrap component (step 3), not in either base.
mock.patch("<TARGET_TOP_NS>.<INITIAL_BASE_NAME>.init_api") fails after the moveThe test references the old residual path; the function now lives in a base.Update mock patch strings to the new location, typically <TARGET_TOP_NS>.<base_name>.<init_func>.
poly check says the residual brick is still declared but its files are gonepyproject.toml [tool.polylith.bricks] still lists the deleted brick.Remove the line from [tool.polylith.bricks] and re-run POLY_CMD_PREFIX sync --quiet.
Application starts but a runtime feature is missing (e.g., logging, DB)A shared init helper was moved into one base only. The other base never calls it.Promote the helper to a shared bootstrap component and call it from every base's startup path.
Verification fails and you can't quickly diagnosePhase commit not yet made.git reset --hard HEAD to roll back to the previous phase's commit and consult the user.

Commit

After verification passes, commit this phase to the migration branch:

bash
git add -A && git commit -m "migrate(<PROJECT>): phase <N> — distribute-wiring"

Substitute <PROJECT>, <N>, and <phase-name> from state.md and the orchestrator's phase table. Do not proceed to the next phase without a clean commit — the per-phase commit is the rollback point for the next phase's failure-mode tables.
