Skill v1.0.0

version: "1.0.0" description: Orchestrate full Julia package freshening: gitignore, deprecations, Aqua, ExplicitImports, struct mutability, design/API/integration reviews, generic indexing, coverage, docstrings, documentation, and formatting

Walk through the following package maintenance steps for the Julia package in the current directory. The package module name is determined by reading Project.toml.

Before starting, check whether the repository has a file .claude/freshen-package-status in the repository's .claude folder:

• If it does not exist, create the file, writing one line per step below in the order they appear. On each line, write "status: name", where status is one of "TODO", "Optional", or "DONE", and name is the title of the step. Items in the steps below already use this format in their markdown header string.
• If it does exist, read the file and determine which items (if any) do not have status "DONE". If no items remain, inform the user and stop executing this skill.

Perform the next unfinished step. If it is "optional" ask the user for their intent, moving to the next if it is declined.

After completing a step:

• mark it "DONE" in .claude/freshen-package-status
• if there are unmerged changes, propose a commit message and ask whether a commit should be made
• check whether any steps remain:
• if so, prompt the user to /clear the session and run /freshen-package again
• if not, inform the user about the current status and ask permission to delete .claude/freshen-package-status

The ordering rationale: cheap deterministic cleanup runs first to clear the deck and to handle the things the reviews would otherwise duplicate (Aqua, ExplicitImports). The three reviews then run on cleaned-up code while the user's attention is fresh — these are the highest-judgment steps. API-dependent finishing work (generic-indexing tests, coverage, docstrings, docs) runs after the reviews so it targets the settled API; generic-indexing tests come first in that group so their src/ fixes and new tests are in place before coverage measures them. Runic formatting is last so the substantive modernization can be bundled into a small number of PRs without being interrupted by the runic step's forced merge to the default branch.

TODO: update .gitignore

Run /freshen-gitignore.

TODO: remove deprecations

Search for @deprecate and Base.depwarn in src/. If none are found, this task can be immediately marked as "DONE" and execution of this step finished.

For each deprecated operation found:

• Remove the deprecation
• Migrate or remove any associated tests (remove if the test's sole purpose was to verify the deprecated syntax and the new functionality is already fully covered; otherwise migrate to test the replacement)
• Update callers within the package if any

This step runs before the reviews because /review-implement may add new deprecation shims for breaking changes; those should remain in place for the current release cycle and be removed by the next freshening pass.

TODO: add Aqua.jl

Run /freshen-aqua.

TODO: add ExplicitImports.jl

Run /freshen-explicit-imports.

TODO: limit struct mutability

Run /limit-struct-mutability.

Optional: design review

Run /review-design. Do not proceed to the next `/freshen-package` step until the resulting plan is implemented to completion via `/review-implement` — re-run /freshen-package only after the plan is fully consumed.

Optional: API review

Run /review-api. Do not proceed to the next `/freshen-package` step until the resulting plan is implemented to completion via `/review-implement` — re-run /freshen-package only after the plan is fully consumed.

Optional: integration review

Run /review-integration. Do not proceed to the next `/freshen-package` step until the resulting plan is implemented to completion via `/review-implement` — re-run /freshen-package only after the plan is fully consumed.

TODO: enforce generic indexing

Run /freshen-generic-axes.

TODO: improve test coverage

Run /freshen-coverage.

TODO: add and improve docstrings

Run /freshen-docstrings.

TODO: add or improve documentation

Run /freshen-docs.

TODO: format with runic

Run /freshen-runic.

This step requires a PR to merge before continuing. Pause and wait for the user to confirm the merge.
