+# CoRIM Generation CLI Commands
+
+This document describes the CLI commands for generating CoRIM (Concise Reference Integrity Manifest) attestation policies.
+
+## Overview
+
+The `cocos-cli policy create-corim` command provides subcommands for generating CoRIM policies for different platforms:
+- **azure**: Generate from Azure Attestation Token
+- **gcp**: Generate from GCP endorsements
+- **snp**: Generate for AMD SEV-SNP (direct host generation)
+- **tdx**: Generate for Intel TDX (direct host generation)
+
+## Commands
+
+### Azure SEV-SNP
+
+Generate CoRIM from an Azure Attestation Token (JWT).
+
+```bash
+cocos-cli policy create-corim azure --token <path-to-token> [--product <product>]
+```
+
+**Flags:**
+- `--token` (required): Path to file containing Azure Attestation Token (JWT)
+- `--product` (optional): Processor product name (default: "Milan")
+
+**Example:**
+```bash
+cocos-cli policy create-corim azure \
+  --token /path/to/token.jwt \
+  --product Milan \
+  > azure-policy.corim
+```
+
+### GCP SEV-SNP
+
+Generate CoRIM from GCP SEV-SNP measurement and endorsements.
+
+```bash
+cocos-cli policy create-corim gcp --measurement <hex> [--vcpu <num>]
+```
+
+**Flags:**
+- `--measurement` (required): 384-bit measurement hex string
+- `--vcpu` (optional): vCPU number (default: 0)
+
+**Example:**
+```bash
+cocos-cli policy create-corim gcp \
+  --measurement abc123... \
+  --vcpu 0 \
+  > gcp-policy.corim
+```
+
+### SEV-SNP (Direct Host)
+
+Generate CoRIM for AMD SEV-SNP platform directly on the host.
+
+```bash
+cocos-cli policy create-corim snp [flags]
+```
+
+**Flags:**
+- `--measurement` (optional): Measurement/Launch Digest (hex string, defaults to zero if not provided)
+- `--policy` (optional): SNP policy flags (default: 0)
+- `--svn` (optional): Security Version Number/TCB (default: 0)
+- `--product` (optional): Processor product name (default: "Milan")
+- `--host-data` (optional): Host data (hex string)
+- `--launch-tcb` (optional): Minimum launch TCB (default: 0)
+- `--output` (optional): Output file path (default: stdout)
+
+**Examples:**
+
+Generate with defaults (zeroed measurement):
+```bash
+cocos-cli policy create-corim snp \
+  --product Milan \
+  --output snp-policy.corim
+```
+
+Generate with custom measurement:
+```bash
+cocos-cli policy create-corim snp \
+  --measurement abc123def456... \
+  --product Genoa \
+  --svn 1 \
+  --policy 0x30000 \
+  --output snp-policy.corim
+```
+
+Generate with host data and launch TCB:
+```bash
+cocos-cli policy create-corim snp \
+  --measurement abc123... \
+  --host-data deadbeef \
+  --launch-tcb 1 \
+  --output snp-policy.corim
+```
+
+### TDX (Direct Host)
+
+Generate CoRIM for Intel TDX platform directly on the host.
+
+```bash
+cocos-cli policy create-corim tdx [flags]
+```
+
+**Flags:**
+- `--measurement` (optional): MRTD measurement (hex string, uses default if not provided)
+- `--svn` (optional): Security Version Number (default: 0)
+- `--rtmrs` (optional): Comma-separated RTMRs (hex)
+- `--mr-seam` (optional): MRSEAM (hex)
+- `--output` (optional): Output file path (default: stdout)
+
+**Examples:**
+
+Generate with defaults (matches legacy script behavior):
+```bash
+cocos-cli policy create-corim tdx \
+  --output tdx-policy.corim
+```
+
+Generate with custom values:
+```bash
+cocos-cli policy create-corim tdx \
+  --measurement abc123def456... \
+  --rtmrs rtmr0,rtmr1,rtmr2,rtmr3 \
+  --mr-seam 789abc... \
+  --svn 2 \
+  --output tdx-policy.corim
+```
+
+## Signing CoRIMs
+
+CoRIMs can be signed using a private key (COSE_Sign1). The generated output will be a COSE-wrapped CoRIM in CBOR format.
+
+### Prerequisite: Generate Signing Key
+
+You will need an EC private key (P-256) in PEM format. You can generate one using `openssl`:
+
+```bash
+openssl ecparam -name prime256v1 -genkey -noout -out private-key.pem
+```
+
+### Signing with CLI
+
+Use the `--signing-key` flag to sign the CoRIM during generation.
+
+**SNP Example:**
+```bash
+cocos-cli policy create-corim snp \
+  --product Milan \
+  --signing-key private-key.pem \
+  --output signed-snp.corim
+```
+
+**TDX Example:**
+```bash
+cocos-cli policy create-corim tdx \
+  --signing-key private-key.pem \
+  --output signed-tdx.corim
+```
+
+### Verification
+
+The output file is a standard COSE_Sign1 message containing the CoRIM. It can be verified using any tool that supports COSE and CoRIM verification, such as the [veraison/corim](https://github.com/veraison/corim) library.
+
+## Output Format
+
+All commands output CoRIM in CBOR (Concise Binary Object Representation) format. By default, output is written to stdout, allowing for piping:
+
+```bash
+# Pipe to file
+cocos-cli policy create-corim snp --product Milan > policy.corim
+
+# Pipe to another command
+cocos-cli policy create-corim tdx | base64
+
+# Use --output flag
+cocos-cli policy create-corim snp --product Milan --output policy.corim
+```
+
+## Integration with Manager
+
+The manager service can dynamically generate CoRIM policies using the same underlying generator package. When `FetchAttestationPolicy` is called:
+
+1. For SNP: Calculates IGVM measurement using the `igvmmeasure` binary
+2. Extracts host data and launch TCB from VM configuration
+3. Generates CoRIM using the `generator` package
+4. Returns CBOR-encoded CoRIM
