What it does

Designing Change is an agent skill from rapidaai/voice-ai. Resolve a non-trivial implementation or architecture decision before coding. Use when ownership, contracts, failure behavior, rollout, or competing approaches require an explicit decision.

Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `agents/openai.yaml` and `examples/sample.md`).

It sits in AI & LLM Engineering, covering Speech recognition and synthesis. The repository describes itself as: Rapida is an open-source, end-to-end voice AI orchestration platform for building real-time conversational voice agents with audio streaming, STT, TTS, VAD, multi-channel…

When your agent uses it

  • Failure behavior
  • Competing approaches require an explicit decision

Example prompts

  • “/designing-change”

Workflow steps

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

  1. State the problem without embedding a preferred solution.
  2. Separate verified facts, assumptions, and unknowns.
  3. Identify the current owner of each behavior and resource.
  4. Describe the smallest viable option plus credible alternatives.
  5. Evaluate each option for simplicity, ownership, contracts, failure recovery, observability, testing, rollout, and rollback.
  6. Reject speculative flexibility and duplicate sources of truth.
  7. Select an option and record why the rejected options are inferior for the current requirement.
  8. Convert the decision into exact acceptance criteria, paths, tests, and operational steps.

What it can do on your machine

Read from SKILL.md and the folder at commit 3c9caac. 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

Designing Change loads about 606 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~606

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 289 words (~606 tokens).

“Choose the smallest design that satisfies verified requirements and make its ownership, contracts, failure behavior, and verification strategy explicit.”
