What it does
Simplify is an agent skill from CherryHQ/cherry-studio-app. Keep code, tests, documentation, configuration, and other changes as tight, clear, performant, and minimal as possible without weakening behavior. Use during implementation to prevent unnecessary complexity, after behavior is proven to consolidate working changes, before handoff for a full branch audit, and when asked to simplify, tighten, clean up, reduce verbosity, remove complexity, or minimize existing work.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Mobile. The repository describes itself as: 🍒 This is the mobile version of Cherry Studio. The licence is AGPL-3.0.

What it can do on your machine
Read from SKILL.md and the folder at commit 172945d. 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
Simplify loads about 1.1k tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 508 words of instructions outside code blocks.
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.

- simplify
- description
- Keep code, tests, documentation, configuration, and other changes as tight, clear, performant, and minimal as possible without weakening behavior. Use during implementation to prevent unnecessary complexity, after behavior is proven to consolidate working changes, before handoff for a full branch audit, and when asked to simplify, tighten, clean up, reduce verbosity, remove complexity, or minimize existing work.
Simplify
Produce the smallest clear implementation that fully satisfies the required behavior. Minimize concepts and moving parts, not line count.
Cadence
- During construction, apply the priorities locally while discovering behavior. Allow clearly temporary instrumentation or scaffolding when it accelerates learning.
- At convergence, once a logical behavior slice passes, simplify that slice, remove superseded attempts, and rerun focused validation.
- Before handoff or merge, compare the full branch with its merge base and reconcile code, tests, comments, documentation, configuration, and relevant history.
Workflow
- Identify the required behavior, invariants, constraints, and non-goals.
- Inspect the relevant diff and separate it into logical concepts. For a final branch audit, compare the full branch with its merge base and check history for superseded attempts when relevant.
- Inspect the existing owners, sources of truth, common path, and decision points before adding anything.
- Choose the design with the fewest necessary concepts and the least work at runtime.
- When changes are requested, implement directly and reuse existing mechanisms where they fit.
- Validate behavior with checks proportional to the risk.
- Review the final code, tests, names, comments, documentation, configuration, and relevant history for anything that no longer earns its complexity.
Simplification Priorities
- Prefer deletion, reuse, or a direct change over a new abstraction.
- Keep one source of truth; avoid mirrored state, overlapping guards, duplicate registries, and compensating mechanisms.
- Avoid speculative fallbacks, compatibility paths, configuration, parameters, and generic APIs.
- Inline one-use helpers when doing so makes the policy clearer at its decision point.
- Prefer straightforward positive control flow over early-return chains or empty branches.
- On hot paths, minimize allocations, callback recreation, subscriptions, renders, passes, I/O, and native work.
- For prose, remove repetition and keep the shortest wording or example that remains self-sufficient.

Existing Work
Establish a passing baseline before simplifying working code. Test one questionable concept at a time, rerun the relevant validation, and restore it if behavior or meaningful coverage weakens. Do not restructure several accumulated fix attempts before establishing which changes are causally necessary.
When duplicate or ineffective regression coverage is suspected, deliberately break the claimed invariant and confirm the remaining test fails. Passing tests alone do not prove that every test or implementation concept is necessary.
Do not rewrite branch history without authorization.
Performance Changes
Name the exact common-path work being removed: allocations, scans, mounts, renders, subscriptions, I/O, or native calls. Control-flow evidence plus regression tests can justify removing work that is structurally unused. Require a benchmark, profile, or repeated repro when an optimization changes semantics or introduces a tradeoff. Do not add complexity for theoretical gains.
Guardrails
- Preserve correctness, required behavior, type safety, distinct regression coverage, and useful clarity.
- Do not replace clear code with compressed or clever code merely to reduce lines.
- Make scoped, behavior-preserving improvements directly. If the better design requires a sweeping API or architecture change, explain and suggest it instead of expanding the task without approval.
- Leave unrelated and user-authored changes untouched.
Stop when every remaining concept supports a requirement, invariant, clarity, or measured performance need. Report only material simplifications, validation, and unresolved opportunities.

Simplify is an agent skill from CherryHQ/cherry-studio-app. Keep code, tests, documentation, configuration, and other changes as tight, clear, performant, and minimal as possible without weakening behavior.
When should I use Simplify?
Simplify fits situations like: mobile work in your project.
How do I install Simplify in Claude Code?
Run `npx skills add CherryHQ/cherry-studio-app --skill simplify -a claude-code`. Or copy the skill folder (.agents/skills/simplify in CherryHQ/cherry-studio-app) into .claude/skills/simplify in your project. Claude Code loads it when a task matches its description.
How do I install Simplify in Codex?
Run `npx skills add CherryHQ/cherry-studio-app --skill simplify -a codex`. Or copy the skill folder (.agents/skills/simplify in CherryHQ/cherry-studio-app) into .agents/skills/simplify in your project. Codex loads it when a task matches its description.
Can I use Simplify in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add CherryHQ/cherry-studio-app --skill simplify -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/simplify, .gemini/skills/simplify, .github/skills/simplify and .opencode/skills/simplify in your project.
What does Simplify need to run?
SKILL.md names no scripts, command-line tools or credentials: Simplify is instructions for the agent only.
Does Simplify access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Simplify safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Simplify use?
Simplify is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Simplify use?
About 1.1k tokens (SKILL.md is roughly 4.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
