Migrate a project's GitHub Copilot configuration — global instructions (.github/copilot-instructions.md), path-scoped instructions (.github/instructions/*.instructions.md), prompts (.github/prompts), custom agents (.github/agents), skills (.github/skills), and MCP (.vscode/mcp.json) — into a target coding agent: Claude Code (CLAUDE.md, .claude/rules, .claude/agents, .claude/commands, .claude/skills), Codex (AGENTS.md, ~/.codex), or opencode (AGENTS.md, .opencode), via a portable AGENTS.md. Use this skill whenever the user wants to migrate, port, consolidate, unify, or reconcile Copilot instructions, custom instructions, rules, prompts, agents, or skills to another coding agent, or mentions copilot-instructions.md, AGENTS.md, CLAUDE.md, moving off Copilot to Claude Code / Codex / opencode, or reconciling a .github and a .claude setup. Always detect the target from the repository FIRST; only ask the user when detection is ambiguous.

opinionizer

webreactiva/skills

Sharpen a hedged, lukewarm draft into a strong, opinionated take that lands and travels — without manufacturing conviction the author doesn't hold. Use this whenever the user is drafting a tweet, thread, LinkedIn post, newsletter intro, blog opener, or any short public writing and says things like "make this more opinionated", "this is too soft", "sharpen this take", "this sounds wishy-washy", "I want a strong opinion / hot take", "esto suena flojo", "hazlo más contundente", "ponle más filo", or whenever a draft clearly contains a real belief buried under hedges and dangling caveats. Also trigger when the user has a defensible view but writes it so cautiously that it carries no edge. Works in any language and ALWAYS returns the sharpened versions in the same language as the input draft.

rubber-duck-chat

webreactiva/skills

Be the user's rubber duck: a warm, energetic chat that helps them think a topic through — mostly by asking sharp, one-at-a-time questions so they reach their own insight, but also by weighing in with your own read and proposing where to dig next so it never becomes aimless interrogation. Use whenever the user says "rubber duck chat", "/rubber-duck-chat", "be my rubber duck", "let me talk this through", "help me think out loud", "ask me questions about X", "talk me through this", or wants a thinking partner to untangle a bug, decision, design, or half-formed idea. If they name no topic, ask what's on their mind. Tell them up front they can wrap up any time and leave with a written takeaway of what they decided and what's still open. Unlike a code review or second-opinion critique, this keeps the user talking and surfaces their own hidden assumptions.

ascii-flow

webreactiva/skills

Create clear, well-aligned ASCII / Unicode-art diagrams for software architecture, workflows, processes, control flow, state machines, sequence diagrams, trees, data structures, memory/bit layouts and tables — the kind that live in code comments, READMEs, design docs, commit messages, chat or a terminal. Use this skill whenever the user asks to "draw", "sketch", "diagram" or "map out" something in plain text or monospace, mentions an "ASCII diagram", "text diagram", "diagram in a comment", "box-and-arrow diagram", a flowchart/architecture/flow they want as text. Also use it when a rendered diagram (Mermaid, Graphviz, an image) is not wanted or not possible and the diagram must be portable plain text. Prefer this over Mermaid whenever the output has to render anywhere with zero tooling.

pre-mortem

webreactiva/skills

Imagine how a proposed change will break in production before writing the code. Use this skill whenever the user says "pre-mortem", "premortem", "what could break", "failure modes", "how will this fail", or after a plan has been approved but before implementation begins for any change touching shared state, payments, migrations, concurrency, auth, or external integrations. Also trigger proactively when the user is about to ship a multi-file change, when the change affects production data, or when "what could go wrong" is the right question to ask before code. The skill produces 3-5 ranked failure modes with likelihood, blast radius, and concrete mitigation, then a single recommendation: ship as-is, harden first, or split the change.

handoff-torch

webreactiva/skills

Pass the torch: generate a handoff document so the current task can be continued in a fresh AI conversation (with any AI coding agent). Use when the user asks to create a handoff, hand off / pass the torch on the task, write a continuation/handover doc, prepare a context dump for a new chat/session, or says things like "handoff doc", "pass the torch", "continue this in a new session", "write a handover", or "prepare a context dump for the next agent". Writes a structured markdown file under docs/handoff/.

rubber-duck

webreactiva/skills

Get a constructive second opinion on a plan, design, diff, or test suite from a DIFFERENT AI model than the one running the current session. Use this skill whenever the user says "rubber duck this", "/rubber-duck", "poke holes in this", "get a critique", "second opinion", "review my plan before I build it", "is this approach sound", or when you are about to commit to a non-trivial design, multi-file change, or architectural decision and want an independent reviewer that does not share your blind spots. Also use it reactively after repeated failed attempts at the same problem. The skill detects the host coding agent AND every other agent CLI installed on the machine, works out which can reach a contrasting model family (the host's own model switch, or a second installed CLI like opencode / codex / copilot / amp / kilo / pi / antigravity), and remembers all of it in an agents.json memory file so the next run is instant.

Migrate Copilot instructions

Migrate a project's AI coding-agent configuration from GitHub Copilot's format into a portable AGENTS.md and the target tool's ecosystem — Claude Code, Codex, or opencode — without losing anything and without creating a "museum of contradictory instructions for robots."

The source is always Copilot's .github/ setup. The target is what varies; detect it from the repo (Step 0). Examples below lean on Copilot → Claude Code because it's the most common request, but the same workflow targets Codex and opencode — the destination homes differ, the method (convert, don't copy) does not.

Core principle (read before touching files)

The bad migration renames copilot-instructions.md to CLAUDE.md and stops. It fails, because each tool reads configuration differently and copying a filename does not copy the behavior.

The good migration moves from "one file per tool" to "one common source with native adapters." AGENTS.md is the natural shared source: Codex and opencode read it natively, and Claude Code can import it. Each tool then reads it through a thin adapter, and Copilot's tool-specific artifacts are re-interpreted into the target's native homes.

Two classes of artifact, handled differently:

Instructions & rules — plain prose. They travel cheaply via wrappers, imports, or sections. A path-scoped rule keeps its glob; only the field name changes (applyTo → paths).
Prompts, agents, skills, MCP — behavioral/executable. They must be re-interpreted per target, never blind-copied, because frontmatter fields, tool names, model names, and argument syntax all differ. cp -R .github/agents .claude/agents looks like it works until you run it.

Keep this distinction front of mind throughout.

Step 0 — Detect the target (do this first, always)

The source is Copilot. Inspect the repository to learn which target ecosystem it's heading toward before asking anything.

# List the agent-config markers that exist in this repo
for p in \
  AGENTS.md AGENTS.override.md CLAUDE.md CLAUDE.local.md GEMINI.md .cursorrules \
  .github/copilot-instructions.md .github/instructions .github/prompts .github/agents .github/skills .vscode/mcp.json \
  .claude .claude/rules .claude/agents .claude/commands .claude/skills .claude/settings.json .mcp.json \
  .codex .codex/config.toml \
  .opencode .opencode/agent .opencode/command .opencode/skills opencode.json; do
  [ -e "$p" ] && echo "FOUND  $p"
done

Interpret the result to confirm the SOURCE (Copilot markers) and pick the TARGET:

Target signal found	Target
`.claude/` or `CLAUDE.md`	Claude Code
`AGENTS.md` + `.codex/` (no `.claude/`)	Codex
`AGENTS.md` + `.opencode/` or `opencode.json`	opencode
`AGENTS.md` only	tool-agnostic — stop at `AGENTS.md`, add adapters on request
only Copilot markers, no target ecosystem	ambiguous → ask (Step 1.5)

Every target produces a clean AGENTS.md as the common source; the target only decides which adapter layer you also generate (CLAUDE.md + .claude/ for Claude, native AGENTS.md + .codex//.opencode/ otherwise). State the detection back in one line — e.g. "Found Copilot config and a .claude/ directory — migrating Copilot → Claude Code." — so the user can correct a wrong guess early.

Step 1 — Inventory the Copilot source

Copilot is not one file. Map every layer that exists, because each lands in a different place in the target. The artifact types are universal:

Global instructions — .github/copilot-instructions.md.
Path-specific instructions — .github/instructions/*.instructions.md (each with an applyTo glob).
Reusable prompts — .github/prompts/*.prompt.md.
Custom agents — .github/agents/*.agent.md.
Skills — .github/skills/<name>/SKILL.md packages.
MCP servers — declared in .vscode/mcp.json.

Read each file you find so you know what you are moving. Flag anything Copilot-specific (mentions of Copilot Chat, VS Code modes, IDE-only tool names) — that gets stripped or re-interpreted, not carried over. references/tool-behaviors.md has the exact home for each artifact in each target — read it before writing any file.

Step 1.5 — Ask only when ambiguous

If Step 0 found only Copilot markers and no target ecosystem, ask one focused question and branch:

"I don't see a target yet. Migrate Copilot toward Claude Code (CLAUDE.md + .claude/), Codex (AGENTS.md + .codex/), or opencode (AGENTS.md + .opencode/)? I can also produce just a shared AGENTS.md plus a thin adapter for each tool you keep using."

Do not ask anything else. Pick the target from their answer.

Step 2 — Build AGENTS.md (the common source)

Convert .github/copilot-instructions.md into a clean, minimal, tool-agnostic AGENTS.md. Convert, do not copy. Keep only what is common and durable:

Stack and versions; build, test, and lint commands.
Naming conventions and folder structure; project entry points.
Hard rules ("don't touch these directories", "update tests when logic changes").

Strip GitHub/IDE-specific language. If Copilot stays in use, leave .github/copilot-instructions.md as a short wrapper pointing at AGENTS.md rather than deleting it (Copilot's coding agent reads a root AGENTS.md too).

Do not silently drop content. If the source had sections that don't fit the minimal common source (e.g. project-specific git policy), tell the user where they went or that they're recoverable from version control.

Step 3 — Wire instructions and rules into the target

Global: give the target its native adapter. Claude Code → a CLAUDE.md importing @AGENTS.md plus any Claude-only lines (or a symlink when there's nothing to add). Codex / opencode → AGENTS.md at the root is already native. Exact wrappers are in references/migration-recipes.md.
Path-scoped rules: keep the glob, change the home. Copilot applyTo → Claude .claude/rules/*.md with paths: frontmatter. Codex / opencode have no native glob-scoped rule file → fold into AGENTS.md sections or per-directory AGENTS.md files (opencode can also list globs under instructions in opencode.json). A thin wrapper that points back to the Copilot rule file avoids duplicating content while Copilot is still in use.

Step 4 — Migrate prompts, agents, and skills (convert, don't blind-copy)

This is the part the lazy migration gets wrong. Each Copilot artifact has a native home in the target and a frontmatter dialect that must be translated. The destination matrix (condensed; full version in references/tool-behaviors.md):

Copilot artifact (source)	Claude Code	Codex	opencode
`.github/prompts/*.prompt.md`	`.claude/commands/*.md` or `.claude/skills/<n>/SKILL.md` → `/n`	skills (`~/.codex/prompts/` deprecated)	`.opencode/command/*.md` → `/n`
`.github/agents/*.agent.md`	`.claude/agents/*.md`	`.codex/agents/*.toml`	`.opencode/agent/*.md`
`.github/skills/<n>/SKILL.md`	`.claude/skills/<n>/SKILL.md` → `/n`	`.agents/skills/<n>/SKILL.md`	`.opencode/skills/` (also reads `.claude/skills/`, `.agents/skills/`)
`.vscode/mcp.json`	`.mcp.json`	`.codex/config.toml`	`opencode.json`

Conversion rules (field-by-field tables and copy-paste examples are in references/migration-recipes.md):

Prompts: the body is usually reusable as-is. Keep description; normalize the model to a name the target runs and drop it if Copilot pinned a model the target can't run; translate argument placeholders to the target's syntax.
Agents: reuse the system-prompt body verbatim, but re-do the frontmatter. Normalize model to the target's aliases, and re-interpret tools — map Copilot's verbs (execute/read/edit/search/web/todo/runSubagent) to the target's tool names, and drop tool references the target doesn't have, especially IDE-only tools and MCP server ids not declared in the target's MCP file. Preserve restrictive intent (a read-only agent stays read-only).
Skills: SKILL.md is a cross-tool open standard (agentskills.io), so the format travels. Copy SKILL.md plus its references/, assets/, scripts/, but drop Copilot sidecar files (*.metadata.json) and review allowed-tools/model per target.
MCP: the server is identical; only the declaration file changes (see matrix). Re-declare; don't copy the file.

Skip what Copilot already retired. Before carrying an artifact over, check its frontmatter or sidecar *.metadata.json for deprecated/excluded/disabled flags and don't migrate those — surface them in the summary instead. When migrating into a concrete project, also flag artifacts that target a stack the project doesn't use (they're inert until invoked, but say so).

If there are many prompts/agents/skills, tell the user this is re-interpretation work, not a copy. A small script that maps frontmatter in bulk is fine, but the model/tool re-interpretation still needs judgment.

Step 5 — Verify before declaring done

AGENTS.md exists, is minimal, and is free of Copilot-specific language.
The target's global adapter is in place (e.g. CLAUDE.md with @AGENTS.md, or native AGENTS.md).
Each path-scoped rule that needs scoping carries the target's glob field (paths: for Claude).
Each migrated prompt/agent/skill sits in the correct directory with valid target frontmatter, a normalized model, and re-interpreted tools.
No CLAUDE.md exceeds ~200 lines (longer files reduce adherence).
List anything still needing hand work (MCP servers to declare, deprecated artifacts skipped, off-stack artifacts), so nothing is silently dropped.

End with a short summary table of what moved where and what still needs hand work.

Output style

Be concrete: show the resulting file tree and the actual file contents you create or edit. Prefer surgical edits over rewrites when a file already exists. Never invent tool behavior — if a claim can't be confirmed from references/tool-behaviors.md or official docs, flag it instead of stating it.
