Round-trip

Digest-verified

Anthropic's terminal agent. The UAP reference adapter — every core component maps natively.

Pack & unpack

# capture an existing Claude Code project as a bundle
uap pack --from claude-code

# install a bundle into a Claude Code project
uap unpack --to claude-code

# convert from Claude Code to any other harness
uap convert --from claude-code --to <harness>

Where components land

Paths are project-scope, relative to the directory you pack/unpack. Every location below is where Claude Code actually reads the component — verified against the official docs.

Component	Location	Support
Instructions	`CLAUDE.md` Managed regions; path-scoped blocks fold in with their scope preserved.	Native
Commands	`.claude/commands/<name>.md`	Native
Subagents	`.claude/agents/<name>.md` Neutral tool names map to Claude tool names (read → Read).	Native
Skills	`.claude/skills/<name>/`	Native
MCP servers	`.mcp.json` stdio, HTTP, and SSE all supported.	Native
Hooks	`.claude/settings.json`	Planned
Permissions	`.claude/settings.json`	Planned
Setup	`session_start hook`	Planned
Env	`.claude/settings.json`	Planned
Files	`project root` Installed verbatim; pack cannot re-attribute plain files yet.	Emulated

Fidelity notes

Components marked Native round-trip losslessly — pack(unpack(D)) ≡ D, digest-verified by the conformance suite.
Components marked Emulated install a faithful approximation and are flagged in the fidelity report so nothing is silently lost.
Components marked Planned are reported as skipped today; the target location shown is where the adapter will install them.
