What it does

Develop Asc Change is an agent skill from rorkai/App-Store-Connect-CLI. Design, implement, and verify behavior changes in App-Store-Connect-CLI. Use when adding or changing a command, flag, API endpoint, output format, exit code, shared CLI behavior, or when fixing or refactoring behavior that requires code and tests.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/test-matrix.md`).

It sits in Mobile, covering App store release, REST APIs and Refactoring. It works with App Store Connect and OpenAPI. The repository describes itself as: Fast, scriptable CLI for the App Store Connect API. Automate TestFlight, builds, submissions, signing, analytics, screenshots, subscriptions, and more. The licence is MIT.

When your agent uses it

  • Changing a command
  • Shared CLI behavior
  • Refactoring behavior that requires code and tests

Example prompts

  • “/develop-asc-change”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Placement in the existing command taxonomy and registry.
  2. Current --help behavior and expected invocation shape.
  3. Exact OpenAPI endpoint, method, request schema, query parameters, and response shape when API-facing.
  4. Flags, output formats, stdout/stderr behavior, and exit codes.
  5. Compatibility, lifecycle, migration, and deprecation impact.
  6. RED-GREEN tests, black-box checks, live verification, edge cases, and failure modes.
  7. Credible alternatives when a material design trade-off exists.

What it can do on your machine

Read from SKILL.md and the folder at commit f7c2064. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

Develop Asc Change loads about 818 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 411 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~818
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

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
Design, implement, and verify behavior changes in App-Store-Connect-CLI. Use when adding or changing a command, flag, API endpoint, output format, exit code, shared CLI behavior, or when fixing or refactoring behavior that requires code and tests.

Develop an ASC CLI change

Follow AGENTS.md for authority, CLI contracts, implementation invariants, validation, and review gates.

Write the design note

For a small fix, record the reproduced failure, intended behavior, and focused check. For new public behavior or compatibility decisions, also record:

  1. Placement in the existing command taxonomy and registry.
  2. Current --help behavior and expected invocation shape.
  3. Exact OpenAPI endpoint, method, request schema, query parameters, and response shape when API-facing.
  4. Flags, output formats, stdout/stderr behavior, and exit codes.
  5. Compatibility, lifecycle, migration, and deprecation impact.
  6. RED-GREEN tests, black-box checks, live verification, edge cases, and failure modes.
  7. Credible alternatives when a material design trade-off exists.

Establish RED

  • For a bug, reproduce it first and add the smallest regression test that fails for the expected reason.
  • For a feature, start with CLI-level coverage of the changed observable contract; add unit or HTTP tests for distinct behavior that those tests do not cover.
  • For a behavior-changing refactor, use existing characterization coverage where sufficient and add coverage for missing behavior before moving code.
  • Run the focused test and record the expected failure before implementation.

Read references/test-matrix.md for applicable CLI, output, artifact, and auth cases. Reuse sufficient existing coverage; do not duplicate shared parser or renderer tests for every command.

Validate API support

  1. Search docs/openapi/paths.txt, then inspect the exact operation in docs/openapi/latest.json.
  2. Apply the endpoint-specific schema checks in AGENTS.md.
  3. If the API cannot support the behavior, implement explicit client-side behavior or document the limitation; do not ship a misleading flag.
Show full SKILL.md (156 more words)Show less

Implement narrowly

Apply AGENTS.md's implementation invariants. Return usage errors with exit code 2.

Reach GREEN and verify

  1. Rerun the focused failing test after each small fix.
  2. Run adjacent package and command tests.
  3. Build a binary at a worktree-specific path and verify realistic invocations, output streams, and exit codes. Do not share a fixed /tmp/asc path with concurrent tasks.
  4. Run a minimal live smoke test when behavior depends on App Store Connect quirks. Prefer read-only calls; live mutations and cleanup require authority under AGENTS.md.
  5. Apply AGENTS.md's validation gate, including command-doc generation when help changes. Public CLI behavior, shared code, release surfaces, and meaningful defect or security fixes require the full gate.

Before handoff, compare the exact branch head with current main read-only. Follow the branch-update rules in AGENTS.md; a newer base alone does not justify changing the branch.

Hand off

Use AGENTS.md's handoff contract; include invocation and compatibility details for public-contract changes.
