update-cli-version — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited update-cli-version (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Use this skill when upgrading the CodeScene CLI (cs) that is embedded in the MCP server binary and installed in the Docker image. The CLI is integrity-verified at build time, so upgrading requires updating the pinned version, checksums, and Dockerfile in lockstep.
| File | What to update | Why |
|---|---|---|
build.rs | CLI_VERSION constant (commit hash) | Pins the exact CLI version downloaded at build time |
cli-checksums.sha256 | SHA-256 hashes for all 5 platform zip files | build.rs verifies the downloaded zip against these hashes at compile time |
Dockerfile | CS_CLI_INSTALLER_SHA256 ARG value | The Docker build verifies the installer script hash before executing it |
cli-checksums.sha256 line 1 | Version comment | Keeps the file self-documenting |
The download URL in build.rs uses the commit hash from CLI_VERSION to pin an exact CLI release: https://downloads.codescene.io/enterprise/cli/cs-{os}-{arch}-{CLI_VERSION}.zip
Download the latest CLI and extract both the version string and commit hash:
curl --proto '=https' --tlsv1.2 -fsSL \
"https://downloads.codescene.io/enterprise/cli/cs-macos-aarch64-latest.zip" \
-o /tmp/cs-cli-version-check.zip
unzip -o /tmp/cs-cli-version-check.zip -d /tmp/cs-cli-version-check
chmod +x /tmp/cs-cli-version-check/cs
/tmp/cs-cli-version-check/cs versionThe output looks like: cs version 1.0.29 (379b46808f26ed3c4eaefc2e11bee6c55dc44000)
The commit hash in parentheses (e.g., 379b46808f26ed3c4eaefc2e11bee6c55dc44000) is used as the CLI_VERSION in build.rs and in download URLs/checksum filenames.
Download each of the 5 platform variants using the commit hash (not -latest) and compute their SHA-256 hashes:
COMMIT_HASH="<commit_hash_from_step_1>"
for variant in macos-aarch64 macos-amd64 linux-amd64 linux-aarch64 windows-amd64; do
url="https://downloads.codescene.io/enterprise/cli/cs-${variant}-${COMMIT_HASH}.zip"
sha=$(curl --proto '=https' --tlsv1.2 -fsSL "$url" | shasum -a 256 | cut -d' ' -f1)
echo "${sha} cs-${variant}-${COMMIT_HASH}.zip"
doneCLI_VERSION in build.rsUpdate the CLI_VERSION constant at the top of the cli_download_url / cli_zip_filename section:
const CLI_VERSION: &str = "<commit_hash_from_step_1>";cli-checksums.sha256Replace the entire file contents with the new hashes and version comment. The format is:
# SHA-256 checksums for CodeScene CLI v<NEW_VERSION> (<COMMIT_HASH>)
# Verify with: shasum -a 256 -c cli-checksums.sha256
# Update by downloading each variant and running: shasum -a 256 <file>
<hash> cs-macos-aarch64-<COMMIT_HASH>.zip
<hash> cs-macos-amd64-<COMMIT_HASH>.zip
<hash> cs-linux-amd64-<COMMIT_HASH>.zip
<hash> cs-linux-aarch64-<COMMIT_HASH>.zip
<hash> cs-windows-amd64-<COMMIT_HASH>.zipCompute the SHA-256 of the installer script:
curl --proto '=https' --tlsv1.2 -fsSL \
https://downloads.codescene.io/enterprise/cli/install-cs-tool.sh \
| shasum -a 256 | cut -d' ' -f1Then update the CS_CLI_INSTALLER_SHA256 ARG in Dockerfile:

Build fails with "SHA-256 checksum verification failed": The downloaded zip doesn't match cli-checksums.sha256. Either the checksums file has a typo, or the CDN is serving different content than what you hashed. Re-run step 2 and compare.
Build fails with "No checksum entry found for '...'": The CLI_VERSION in build.rs doesn't match the commit hash used in cli-checksums.sha256 filenames. Ensure they are identical.
Dockerfile build fails with "sha256sum: WARNING: 1 computed checksum did NOT match": The installer script changed. Re-run step 5 to get the new hash.
