[cli-docs] Claude Code: New `/deep-research` workflow command and `/feedback` alias `/share` added

[github-actions]

Claude Code CLI Changes

Detected on: 2026-06-05 | Previous snapshot: 2026-05-29

New Slash Commands

• /deep-research <question> — [Workflow] "Fan out web searches on a question, fetch and cross-check sources, and synthesize a cited report." This is a new bundled workflow (not a skill), allowing Claude Code users to perform deep multi-source research directly from the CLI.

---

Changed Slash Commands / Aliases

• /feedback [report] — The alias /share was added. Before: aliases were only /bug. After: aliases are /bug, /share.

  • Note: In Copilot CLI, /share maps to the session export command (/share [file|html|gist] [session|research] [PATH]). These are different semantics.

• /clear [name] — An optional [name] parameter was added. Users can now pass a name to label the previous conversation in the /resume picker when clearing.

  • Before: /clear — start new conversation; aliases: /reset, /new
  • After: /clear [name] — start new conversation; pass name to label previous conversation in /resume picker; aliases: /reset, /new

Impact on compatibility layer

/deep-research → Potential new mapping opportunity:

• Claude Code's /deep-research <question> is a research-oriented workflow with no exact equivalent in Copilot CLI's documented slash commands.
• Copilot CLI has /research TOPIC (deep research using GitHub search and web sources), which is the closest analog.
• Opportunity: The cpc wrapper could translate /deep-research → /research with a note that the tool chain differs (Claude Code uses web search; Copilot uses GitHub + web).

/feedback alias /share:

• The /share alias for /feedback in Claude Code conflicts in naming with Copilot CLI's /share [file|html|gist] (a session export command).
• Risk: If a user types /share in a mapped context, it would invoke different behaviors on each CLI. The wrapper should be aware of this ambiguity.
• No existing mapping currently broken, but documentation should note the semantic difference.

/clear [name]:

• Copilot CLI's /clear [PROMPT] accepts an optional prompt (different semantics — it sends a message to start the new conversation, not a name).
• The new [name] parameter in Claude Code has no direct equivalent in Copilot.
• No mapping change needed, but the difference in behavior should be documented.

Files to update

• cpc — Add a mapping rule for /deep-research → /research (the Copilot analog). Consider documenting that this is a best-effort translation since the underlying research pipelines differ.
• skills/claude-compat/SKILL.md — Add a row for /deep-research → /research in the slash command mapping table, noting the semantic difference.
• README.md — Update the Limitations or Mapping tables if /deep-research is mentioned anywhere. Note the new /share alias ambiguity.
