Review first — review before installing

Open the source and read safety notes before installing.

Safety notes

  • Not every Claude Code command or MCP tool exists on other platforms; do not imply feature parity without verification.
  • Adapted skills must preserve destructive-action warnings and approval requirements from the source workflow.
  • Cross-platform copies should not strip `safetyNotes` or `privacyNotes` to save space.
  • Platform-specific secret handling differs; never copy Claude Code env patterns blindly into other hosts.
  • This skill produces adaptation plans; it must not run destructive commands on the target platform without explicit approval.

Privacy notes

  • Adaptation reviews may expose internal runbooks, customer workflows, and repository conventions embedded in source skills.
  • Generic AGENTS exports shared across teams can leak path patterns and tool names if pasted into public issues.
  • Public adaptation summaries should describe platform gaps and preserved boundaries, not full internal skill bodies.

Prerequisites

  • The source Claude Code `SKILL.md` or HeyClaude capability pack to adapt.
  • The target platform or host (Codex, Cursor, Windsurf, Generic AGENTS, or mixed).
  • Knowledge of platform-specific skill, rule, or AGENTS.md conventions on the target host.
  • Redacted examples of commands, tools, or MCP dependencies the source skill assumes.

About this resource

Knowledge Freshness

This capability pack is grounded in Claude Code skills and features overview documentation verified on 2026-06-14. Target platform skill formats and tool surfaces change independently; prefer live host documentation when adapting workflows.

Source Verification Notes

Verified against official Claude Code skills documentation and the public Anthropic claude-code repository on 2026-06-14:

  • Claude Code skills live in SKILL.md files with YAML frontmatter controlling description, allowed tools, model invocation, and supporting references.
  • Skill descriptions can load at session start when model invocation is enabled, making portability decisions affect token cost on every host that imports them.
  • Claude Code supports project, user, and plugin skill locations with different scope semantics that do not map one-to-one to Cursor rules or Codex AGENTS files.
  • Official skills documentation describes disable-model-invocation, allowed-tools, and user-only skills—features that require explicit mapping on other platforms.
  • HeyClaude capability packs document Compatibility sections for native versus manual adaptation; this skill operationalizes that pattern.

Scope Note

This is not a fully automated converter. Use it as a reusable adaptation workflow when porting source-backed Claude Code skills to other agent hosts while preserving safety, privacy, and output contracts.

Core Workflow

  1. Extract the source contract: trigger phrase, required outputs, production rules, safety notes, privacy notes, and retrieval sources.
  2. Inventory Claude Code-specific dependencies: slash commands, MCP tools, hooks, subagents, compaction behavior, and path-scoped rules.
  3. Profile the target host: skill/rule file format, tool availability, context loading behavior, and approval or sandbox constraints.
  4. Map metadata fields: title, description, tags, prerequisites, and verification status to the closest supported equivalents.
  5. Replace non-portable steps with manual adaptation instructions rather than silently dropping them.
  6. Preserve Production Rules, Safety Notes, and Privacy Notes verbatim unless the target platform requires equivalent stronger wording.
  7. Add a Compatibility section stating native versus manual adaptation paths.
  8. Define a verification checklist on the target host with one read-only dry run.
  9. Document remaining gaps explicitly in the adaptation summary.

Capability Scope

  • Source skill scope and dependency inventory.
  • Target platform capability gap assessment.
  • Adapted workflow with preserved safety boundaries.
  • Invocation and metadata mapping plan.
  • Verification checklist for adapted hosts.
  • Privacy-safe adaptation reporting.

Compatibility

Native

  • Claude Code / Claude: use as an Agent Skill when exporting HeyClaude capability packs to team runbooks or reviewing cross-platform skill ports.

Manual Adaptation

  • Codex, Cursor, Windsurf, and Generic AGENTS workflows: this skill is the manual adaptation framework itself; apply its output contract on the target host.

Required Inputs

  • Source SKILL.md or capability pack MDX with frontmatter and body sections.
  • Target platform name and supported skill/rule conventions.
  • List of commands, tools, and integrations the source skill requires.
  • Stakeholder approval requirements for destructive or production-impacting steps.

Production Rules

  • Never claim feature parity across platforms without verifying tool support.
  • Preserve safety and privacy notes even when shortening workflow steps.
  • Mark Claude Code-only commands explicitly rather than omitting them silently.
  • Prefer manual adaptation sections over broken automatic translations.
  • Keep retrieval sources attached to adapted skills for reviewer verification.
  • Redact internal examples before publishing adapted skills to shared catalogs.
  • Re-verify adapted skills after major host upgrades or model changes.

Review Matrix

Source dependency Claude Code Other hosts Adaptation
/context slash command Native Varies Document manual equivalent or omit
MCP tools Native Varies List required servers or manual steps
Subagents Native Limited Split into sequential manual tasks
SKILL frontmatter Native Partial Map to closest metadata block
Hooks Native Rare Externalize as pre-step checklist
Compaction rules Native N/A Note as Claude Code-specific context

Output Contract

  1. Source scope and non-portable dependency inventory.
  2. Target platform capability gap assessment.
  3. Adapted workflow with preserved safety and privacy notes.
  4. Invocation and metadata mapping plan.
  5. Verification checklist for the adapted host.
  6. Privacy-safe adaptation summary for reviewers or team docs.

Duplicate Check

Checked content/skills, content/guides, generated catalog text, and open pull requests for agent skills cross-platform adapter, SKILL.md portability, and platform mapping workflows. Individual skills include Compatibility sections, but no skills entry provides a reusable cross-platform adaptation capability pack with gap matrix and output contract.
