Releaseguard

Scan, harden, sign, and verify release artifacts with ReleaseGuard — the artifact policy engine for dist/ and release/ outputs.

ReleaseGuard Skill

ReleaseGuard is an artifact policy engine. Use it to scan build outputs for secrets, misconfigurations, and supply-chain risks; harden and fix them; generate SBOMs; sign artifacts; and verify release integrity.

Install ReleaseGuard

Preferred — Homebrew (macOS / Linux, no remote script execution):

brew install Helixar-AI/tap/releaseguard

Alternative — manual download from GitHub Releases (review before running):

# 1. Review the install script before executing:
curl -sSfL https://raw.githubusercontent.com/Helixar-AI/ReleaseGuard/main/scripts/install.sh | less

# 2. If satisfied, run it:
curl -sSfL https://raw.githubusercontent.com/Helixar-AI/ReleaseGuard/main/scripts/install.sh | sh

Alternative — direct binary download (no shell script):

# Replace VERSION, OS, and ARCH as appropriate (linux/darwin, amd64/arm64)
curl -sSfL https://github.com/Helixar-AI/ReleaseGuard/releases/latest/download/releaseguard-VERSION-OS-ARCH.tar.gz \
  | tar -xz releaseguard
sudo mv releaseguard /usr/local/bin/releaseguard

Note: The install script is MIT-licensed and open-source at https://github.com/Helixar-AI/ReleaseGuard/blob/main/scripts/install.sh Review it before executing in sensitive environments.

External Services

Some commands interact with external services. This is documented per-command below. No data is sent externally unless you explicitly invoke the relevant flag or mode:

Feature	External Service	Triggered by
CVE enrichment	OSV.dev (read-only, no auth)	sbom --enrich-cve or vex
Keyless signing	Sigstore / Fulcio (requires OIDC token)	sign --mode keyless
Cloud obfuscation	ReleaseGuard Cloud API	obfuscate --level medium/aggressive
SLSA Provenance L3	ReleaseGuard Cloud API	Cloud plan only

Credentials: Keyless signing requires an OIDC token (available in GitHub Actions, GitLab CI, etc.). Local signing requires a private key file you supply with --key. Cloud features require RELEASEGUARD_CLOUD_TOKEN. No credentials are used by default for check, fix, sbom, pack, report, or verify.

Commands

Check / Scan — releaseguard check <path>

Scan an artifact path and evaluate the release policy. No external network calls.

Trigger phrases: "scan", "check", "audit", "analyze release", "inspect dist", "any secrets", "find vulnerabilities"

releaseguard check <path>
releaseguard check <path> --format json
releaseguard check <path> --format sarif --out results.sarif
releaseguard check <path> --format markdown --out report.md

• Default format: cli (human-readable)
• Other formats: json, sarif, markdown, html
• Exit code 0 = PASS, non-zero = FAIL

---

Fix — releaseguard fix <path>

Apply safe, deterministic hardening transforms. No external network calls.

Trigger phrases: "fix", "harden", "apply fixes", "remediate", "auto-fix release"

releaseguard fix <path>
releaseguard fix <path> --dry-run   # preview without applying

---

SBOM — releaseguard sbom <path>

Generate a Software Bill of Materials.

Trigger phrases: "sbom", "software bill of materials", "dependencies", "generate bom"

releaseguard sbom <path>                     # no network calls
releaseguard sbom <path> --format spdx
releaseguard sbom <path> --enrich-cve        # fetches CVE data from OSV.dev (read-only)

• Default format: cyclonedx
• --enrich-cve makes read-only requests to OSV.dev; no credentials required

---

Obfuscate — releaseguard obfuscate <path>

Apply obfuscation to release artifacts.

Trigger phrases: "obfuscate", "strip symbols", "protect binary"

releaseguard obfuscate <path> --level light   # OSS — no network calls
releaseguard obfuscate <path> --level medium  # requires RELEASEGUARD_CLOUD_TOKEN
releaseguard obfuscate <path> --dry-run

Levels:

• none / light — local, no external calls (OSS)
• medium / aggressive — calls ReleaseGuard Cloud API; requires RELEASEGUARD_CLOUD_TOKEN

---

Harden — releaseguard harden <path>

Full hardening pipeline: fix + obfuscate + DRM injection.

Trigger phrases: "full harden", "harden release", "full hardening pipeline"

releaseguard harden <path> --obfuscation light    # no network calls
releaseguard harden <path> --obfuscation medium   # requires RELEASEGUARD_CLOUD_TOKEN
releaseguard harden <path> --dry-run

---

Pack — releaseguard pack <path>

Package an artifact into a canonical archive. No external network calls.

Trigger phrases: "pack", "package artifact", "create archive"

releaseguard pack <path> --out release.tar.gz
releaseguard pack <path> --out release.zip --format zip

---

Sign — releaseguard sign <artifact>

Sign an artifact and its evidence bundle.

Trigger phrases: "sign", "cosign", "keyless sign", "sign artifact"

# Keyless (Sigstore/Fulcio) — requires OIDC token; use in CI environments
releaseguard sign <artifact> --mode keyless

# Local signing — no external calls; requires private key file
releaseguard sign <artifact> --mode local --key signing.key

• keyless mode contacts Sigstore's Fulcio CA and Rekor transparency log
• local mode is fully offline; key stays on disk

---

Attest — releaseguard attest <artifact>

Emit in-toto and SLSA provenance attestations.

Trigger phrases: "attest", "provenance", "slsa", "in-toto"

releaseguard attest <artifact>

---

Verify — releaseguard verify <artifact>

Verify artifact signatures and policy compliance. No credentials required for verification.

Trigger phrases: "verify", "check signature", "validate artifact"

releaseguard verify <artifact>

---

Report — releaseguard report <path>

Export a scan report. No external network calls.

Trigger phrases: "report", "export report", "compliance report"

releaseguard report <path> --format sarif --out results.sarif
releaseguard report <path> --format html --out report.html

---

VEX — releaseguard vex <path>

Enrich SBOM with VEX vulnerability data. Makes read-only requests to OSV.dev.

Trigger phrases: "vex", "vulnerability data", "enrich sbom"

releaseguard vex <path> --sbom .releaseguard/sbom.cdx.json --out vex.json

---

Typical Workflows

Quick scan (no network, no credentials)

releaseguard check ./dist

Full pipeline (CI with keyless signing)

releaseguard check ./dist
releaseguard fix ./dist
releaseguard sbom ./dist
releaseguard pack ./dist --out release.tar.gz
releaseguard sign release.tar.gz --mode keyless   # OIDC token required
releaseguard attest release.tar.gz
releaseguard verify release.tar.gz

Offline pipeline (no network, local key)

releaseguard check ./dist
releaseguard fix ./dist
releaseguard sbom ./dist
releaseguard pack ./dist --out release.tar.gz
releaseguard sign release.tar.gz --mode local --key signing.key
