Install
npx skills add gopigment/ai-plugins --skill editing-an-existing-application
Runs the open skills CLI and installs the skill for your agent (Claude Code, Codex, Cursor …). Alternatively copy the skill folder into .claude/skills/ or upload it in Claude.ai under Settings → Skills.
As a Claude Code plugin
/plugin marketplace add anthropics/claude-plugins-official
/plugin install pigment@pigment
This skill is part of the plugin “pigment”. In Claude Code the plugin installs it together with the plugin’s other skills, commands and hooks.

Description from the SKILL.md in the source repository.
Questions about editing-an-existing-application
What does the editing-an-existing-application skill do?
Planning skill. Use when modifying, extending, refactoring, or restructuring an existing Pigment application. Covers discovery, impact analysis, change planning, and phased execution. Do not use for greenfield builds (use building-a-full-application instead).
How do I install editing-an-existing-application?
In a terminal: npx skills add gopigment/ai-plugins --skill editing-an-existing-application. The skills CLI asks which agents to install it for. In Claude.ai you can upload the skill folder as a ZIP under Settings → Skills.
Which agents can use editing-an-existing-application?
Skills use the open SKILL.md format, which Claude Code, Claude.ai, the Claude API, OpenAI Codex, Cursor, Gemini CLI and other agents support.
Is editing-an-existing-application safe to use?
Our automatic check found no risky patterns (piped shell scripts, hidden characters, secret access, prompt overrides). It is not a full audit – read the SKILL.md and any scripts before installing.

Execution skill. Use when sharing metrics or lists between Pigment Applications via Libraries and cross-Application formula references.
Execution skill. Use when investigating slow inputs, slow calculations, or timeouts with the Performance Insights tools (performance_profile_change, performance_profile_change_scope_details, performance_slowest_changes, performance_changes_statistics, get_top_blocks_by_performance). Covers which tool to call, the includeAllExecutions default, reading change profiles (X/Y scope, contention, impacted viewed data), drilling into the scoped dimensions of some executions, locating the bottleneck, and comparing timings before/after a fix. Always profile before formula changes; never optimize from assumptions.
Execution skill. Use when writing PREVIOUS, PREVIOUSOF, or PREVIOUSBASE formulas, configuring iterative calculation cycles, or debugging circular dependency errors.
Execution skill. Use when naming or organizing Pigment Applications, folders, and blocks so models stay navigable, formula-safe, and consistent across teams.
