Verdict
COMMENT - This is a tooling/skills PR (APM install path, an optional security-audit skill, and a SkillSpector baseline); it contains no production Go/reconciler code, leaks no secrets, and pins its APM dependencies to commits. It is safe to iterate on, but I found several error-handling, supply-chain, and consistency issues worth addressing before merge, none of which are blockers.
Hi, Amber here. I reviewed the APM/security-tooling changes against HyperShell's conventions and specs. Most of the standard Go/control-plane checks are N/A here (no handlers, reconcilers, pod specs, or API changes), so I focused on the shell/skill logic, supply-chain posture, and cross-PR coordination.
Findings
Major
1. apm-install.sh aborts with an opaque traceback if the SkillSpector scan produces no/invalid JSON — scripts/apm-install.sh:114-121
The scan is run with || true, so a scanner failure (crash, non-zero exit, no output file) is swallowed. The very next step unconditionally does open(scan_out) / json.load(f) in the embedded Python. If the file is missing or partial, Python raises FileNotFoundError/JSONDecodeError, which propagates as a non-zero exit and fails make apm-install / make apm-install-force with a stack trace instead of the intended actionable message. Guard for the file existing and for JSON-decode errors, and emit a clear "scan did not complete" warning (matching the graceful degradation used elsewhere in the script). Confidence: High.
Minor
2. Harness bootstrap tracks moving origin/main with no commit pin — skills/security/run-security-audit/SKILL.md:112-120
Step 2 does git fetch origin main --depth 1 + git reset --hard origin/main, and Step 3 then pip installs and executes Python from whatever main currently is. --require-hashes on requirements.lock is good, but the executed harness scripts themselves are unpinned, so runs are non-reproducible and implicitly trust the tip of an external repo. Consider pinning to a known tag/commit (overridable via env). This is opt-in and gated behind a PAT, hence Minor. Confidence: Medium.
3. SkillSpector baseline excludes whole directories, including the script this PR adds — .skillspector-baseline.yaml:5-13
scripts/* (and components/*, deploy/*, specs/*) are suppressed wholesale. That means scripts/apm-install.sh — which contains embedded Python and process orchestration — is never scanned by the tool this PR introduces. Reasonable for non-skill dirs, but consider narrowing so genuinely executable helpers still get coverage. Confidence: Medium.
4. Divergent SkillSpector invocations across entry points — apm.yml:20-21, Makefile (apm-audit → apm run audit), scripts/apm-install.sh:110-114
apm.yml's audit script runs skillspector scan . --no-llm --baseline ... (no --format json/--output), while apm-install.sh runs it with --format json --output and parses the result in Python, and make apm-install calls the script directly rather than apm run install. Three slightly different scan behaviors for one tool invites drift. Consolidate on one invocation path. Confidence: High.
5. Redundant .gitignore entries — .gitignore:31-33
.claude/agents, .claude/commands, .claude/skills are added immediately above the existing .claude/ catch-all (line 36), which already ignores everything beneath it. Harmless but dead lines. Confidence: High.
6. Stale Step 8 recommendation — skills/security/run-security-audit/SKILL.md:241,248
The skill twice recommends the user add security-audit/ to .gitignore, but this PR already does so (.gitignore:42). Drop the now-redundant guidance. Confidence: High.
Cross-PR coordination
I compared #109 against all 23 other open PRs in openshift-online/hypershell, focusing on goals, ownership boundaries, interfaces, data models, and change ordering.
Other open PRs (for the record): #216 fix(console): OpenShift Route ingress; #214 Hypershell-112 UI adjustments; #212 feat(e2e): performance harness; #211 fix(kind): gateway metrics + control-plane connectivity; #210 [HYPERSHELL-259] gateway-matched CLI install; #209 HYPERSHELL-112 Dashboard UI; #208 [HYPERSHELL-129] sandbox-connect UI section; #207 feat: reconcile-to-request trace correlation; #206 [HYPERSHELL-133] hsctl login; #201 [HYPERSHELL-45] Red Hat openshell images; #200 docs: control-plane reconciliation contract; #194 feat(control-plane): adopt upstream OpenShell Helm chart; #189/#188/#135 Konflux dependency bumps; #185 docs(control-plane): world-sync; #182 fix(auth): JWT audience; #179 fix(control-plane): reconcile Keycloak clients; #151 spec: gate re-provisioning; #150 [HYPERSHELL-111] kind LOCAL_IMAGES; #148 docs: OpenShell branch build spec; #75/#73 Konflux dependency bumps.
No material design, logical, structural, or ordering conflicts found.
Details of the overlaps I examined and why they are not material conflicts:
apm.yml/apm.lock.yamlownership — #109 is the only open PR that touches the APM manifest or lockfile (it also bumpsagentic-sdlc7995f9b→b04b117and adds six pinned ProdSec skills). No competing dependency-management change exists, so there is no ownership contention over the APM data model.Makefile— also edited by #212 (e2e-performance*targets), #211, and #150 (kind targets). #109 adds a new, self-containedAPMsection andapm-install/apm-audit/apm-install-forcetargets in a different region. These are additive and non-competing; at worst a trivial textual merge in the sharedhelp:echo block — not a design conflict.CLAUDE.md— also edited by #214 and #209 (dashboard). #109's edits are confined to the skills index and command list. Additive, no conflicting claims.skills/RECONCILE.md— #109 does not modify it, but its baseline pins rule suppressions (MP3,PE3) to specific content in that file, which #216/#212/#194/#151 do edit. This is a soft coupling (suppressions could become stale), not a design conflict — flagging only so maintainers re-run SkillSpector after those merge.- ProdSec skill topics vs. in-flight work — #109 pulls in
helm-chart-securitywhile #194 adopts an upstream Helm chart, andlinux-capabilities/tls-compliancerelate to security specs. These are complementary review aids, not competing implementations.
If maintainers want one coordination decision: settle the merge order of #109 relative to any Makefile-touching PR (#212/#211/#150) only to avoid a textual help: conflict — no behavior depends on the order.

NVIDIA SkillSpector JSON report execution_successful false exit code 2
💡 Result:
In NVIDIA SkillSpector, an exit code of 2 combined with "execution_successful": false in a JSON report indicates a fatal execution or input failure [1][2][3]. This error signifies that the scanning process was unable to complete its intended security analysis [1][2]. Unlike exit code 1, which indicates the scan completed but found security risks (a "DO_NOT_INSTALL" recommendation) [1][2], exit code 2 is a blocking validation error caused by issues such as bad input, unreadable source files, or internal system failures [1][2][4]. For automated CI/CD pipelines or programmatic integrations, it is recommended to treat both a non-zero exit code and the JSON field "execution_successful": false as indicators that the validation has failed [2][4][3]. Integration logic should ideally check these indicators to prevent potentially unsafe or unverified skills from proceeding through the pipeline [4][3]. For diagnosis when this error occurs, you should examine the report's metadata—specifically the "analysis_completeness" and "ledger_exceptions" fields—which may provide further details on why the scan could not be completed [4][5][6].

Fail --force when execution_successful is not true.
The script ignores this field before filtering issues. A report with execution_successful: false and no HIGH or CRITICAL issue can therefore make --force succeed after an incomplete scan. Call scan_incomplete before reading issues.

Git official documentation credential helpers GIT_ASKPASS arbitrary environment variables git clone authentication
💡 Result:
Git authentication, particularly for operations like git clone, is managed through two primary mechanisms: credential helpers and interactive fallback prompts [1][2]. Credential Helpers Credential helpers are external programs that Git invokes to securely fetch, store, or erase credentials (username/password pairs) [1][3]. - Configuration: You can configure helpers using the credential.helper setting in your Git configuration (e.g., git config --global credential.helper ) [1][4]. - Execution: When Git requires credentials, it executes the helper. If the helper name is not an absolute path, Git prepends git-credential- to it and executes the resulting command via the shell [1][5]. - Custom Helpers: You can define custom, inline credential helpers using shell syntax starting with an exclamation mark (!) [6][7]. This allows you to reference arbitrary environment variables directly within the shell command to dynamically provide credentials (e.g., git config credential.helper '!f { echo "username=$GIT_USER"; echo "password=$GIT_PASSWORD"; }; f') [6]. Interactive Fallback (GIT_ASKPASS) If no credential helpers are configured or if they fail to provide credentials, Git falls back to an interactive prompting mechanism [1][8]. The order of operations for finding a program to prompt the user is [1][9]: 1. GIT_ASKPASS: If this environment variable is set, Git invokes the specified program and reads the input from its standard output [1][10]. 2. core.askPass: If GIT_ASKPASS is unset, Git checks this configuration variable [1][8]. 3. SSH_ASKPASS: If the above are unset, Git checks this environment variable [1][8]. 4. Terminal: If none of the above are configured, Git prompts directly on the terminal [1][9]. Security Note When using arbitrary environment variables in authentication scripts or URLs, be aware that some tools (such as certain Python git libraries) may perform environment variable expansion on remote URLs before they are passed to Git, which can lead to inadvertent credential disclosure if secrets are embedded in the URL [11]. Always prefer Git-native configuration mechanisms like credential helpers or ASKPASS variables over embedding credentials directly in command-line arguments or URLs [1][6].

Wire the documented GitLab credentials into bootstrap.
README.md requires GITLAB_HOST and GITLAB_APM_PAT, but git clone "$HARNESS_URL" passes neither to Git’s credential system. Git does not consume arbitrary GITLAB_* variables. On a clean machine, bootstrap can prompt or fail instead of using the documented PAT.

Resolve the audit target from the Git root.
Line 143 uses pwd, while Line 110 resolves the Git root. If the skill is invoked from a repository subdirectory, the audit scans only that subdirectory and writes reports outside the documented repository-root location. Set TARGET_DIR from git rev-parse --show-toplevel.

Keep optional scanner coverage consistent with the prerequisite contract.
Step 0 recognizes govulncheck, syft, and grype, but Step 6 neither invokes them nor records them when installed. Add supported harness invocations, or remove these tools from the advertised contract after checking the pinned harness documentation.

Verdict
This PR adds agent-skill security tooling (a /run-security-audit skill, a SkillSpector scan wired through make apm-install, and a curated set of ProdSec APM skills) entirely in shell scripts, Markdown, and manifest files. The work is well-constructed - pinned refs, --require-hashes, set -euo pipefail, artifact .gitignore entries, and no secret logging - but a couple of wiring gaps between the documented auth model and the actual clone command are worth resolving before this is relied on.
Because this change is dev/CI agent tooling rather than production Go, control-plane, or API-server code, most HyperShell runtime conventions (panic-free handlers, error wrapping, SecurityContext, reconcile-vs-create) do not apply here. The findings below are about the correctness and self-consistency of the tooling itself.
Findings
[Major] Documented GitLab auth is not consumed by the harness clone (skills/security/run-security-audit/SKILL.md, Step 2)
The README instructs users to export GITLAB_HOST and GITLAB_APM_PAT (with read_repository scope) before running, but the bootstrap block runs a plain git clone https://gitlab.cee.redhat.com/... that never references those variables. Unless the user already has a git credential helper / .netrc configured for that host, the documented PAT will not authenticate the clone, so the "just set these two env vars" prerequisite is misleading and the skill will fail auth for exactly the audience it targets. Either wire the token into the clone via a credential helper (e.g. an ephemeral GIT_ASKPASS/credential.helper using GITLAB_APM_PAT) or document that the PAT must be pre-registered with git for $GITLAB_HOST. Confidence: Medium.
[Minor] Possible install-hook recursion via scripts.install (apm.yml)
apm.yml sets scripts.install: scripts/apm-install.sh, and scripts/apm-install.sh itself runs apm install. If apm install triggers the scripts.install lifecycle hook (rather than only apm run install), this recurses. It most likely does not (the PR test plan implies make apm-install was run successfully), but please confirm APM's semantics so a future APM version change can't turn this into a fork bomb. Confidence: Low.
[Minor] Prerequisite install hint for python3 is gated on skillspector presence (scripts/apm-install.sh)
In the STOP block, the python3 hint is only printed when skillspector is already installed. In --force (CI) mode, python3 is required unconditionally, so a run failing solely on missing python3 will exit without printing its install hint. Print the python3 hint whenever it is the missing required tool. Confidence: High.
[Minor] Unchecked dict key in scan result parsing (scripts/skillspector-scan.sh)
In the severity-report loop, severity is read via .get() but issue["id"] uses direct indexing; a finding missing id would raise KeyError inside the already-failing path and mask the real report. Use issue.get("id", "?") for consistency with the surrounding .get() calls. Confidence: Medium.

[Major] This git clone targets internal GitLab over HTTPS but never references the GITLAB_APM_PAT/GITLAB_HOST variables the README tells users to export. Plain git clone will only succeed if the host already has a git credential helper/.netrc configured, so the documented "set two env vars" prerequisite won't actually authenticate this clone. Wire the PAT into the clone (e.g. an ephemeral GIT_ASKPASS or credential.helper using GITLAB_APM_PAT), or document that the PAT must be pre-registered with git for $GITLAB_HOST.

[Minor/question] scripts.install points at scripts/apm-install.sh, and that script runs apm install. If apm install fires the scripts.install lifecycle hook (not just apm run install), this recurses. Please confirm APM's semantics so a future APM change can't turn make apm-install into a fork bomb.

[Minor] The python3 install hint is only printed when skillspector is already installed. In --force mode python3 is required unconditionally, so a run that fails solely because python3 is missing exits without printing its hint. Print the python3 hint whenever it is the missing required tool.

[Minor] severity is read with .get() but id uses direct indexing (issue["id"]). A finding missing id would raise KeyError inside this already-failing report path and hide the real findings. Use issue.get("id", "?") for consistency.

Verdict
This PR adds opt-in agent-skill security tooling (an /run-security-audit skill, make apm-install, a SkillSpector scan wrapper, and a curated set of ProdSec APM skills). The design is sound and security-conscious (PAT passed via ephemeral GIT_ASKPASS, hashed pip installs, no secrets logged), but the SkillSpector gate and the apm run audit wiring have correctness gaps worth confirming before this becomes a relied-upon security check.
Strengths
- The GitLab PAT is never embedded in a URL or logged — it flows through an ephemeral
GIT_ASKPASShelper cleaned up onEXIT(SKILL.mdStep 2). Good secret hygiene. - Harness Python deps are installed with
pip install --require-hashes -r requirements.lock(SKILL.mdStep 3) — pinned and hash-verified. - The harness ref is pinned (
HARNESS_REF/AI_SECURITY_HARNESS_REF) for reproducible audits, and generated artifacts are added to.gitignore. - The
scripts/apm-install-hook.shno-op explicitly documents theapm installrecursion hazard.
Findings
[Major] SkillSpector gate silently passes if the JSON schema differs — scripts/skillspector-scan.sh L98–L118. The pass/fail decision reads specific keys: issues, per-issue severity ∈ {HIGH,CRITICAL}, suppressed_count, and location.start_line. If the installed SkillSpector version emits any other shape (e.g. findings instead of issues, or a nested severity), severe is empty and the scan reports "passed — no HIGH or CRITICAL findings" even when findings exist. For a tool intended as a security gate this is false confidence. Recommend asserting the expected top-level key exists (fail/warn if issues is absent) or adding a tiny fixture self-test so a schema drift is caught rather than silently swallowed. Confidence: Medium.
[Major] apm run audit may recurse — apm.yml L21 defines scripts.audit: "apm audit && scripts/skillspector-scan.sh --force", and the Makefile apm-audit target (L240) runs apm run audit. The sibling apm-install-hook.sh comment states that calling apm install from scripts.install recurses; by the same mechanism, apm audit invoked from inside scripts.audit will re-trigger the audit script and loop. Please confirm apm audit is a distinct builtin (not an alias for apm run audit); if it is not, call the scan directly here instead of shelling back into apm. Confidence: Medium.
[Minor] Scanner failures are swallowed in non-force mode — scripts/skillspector-scan.sh L63–L67 runs skillspector scan ... || true, and the parser then exits 0 (with a warning) when output is missing/invalid unless --force is set. A crashed scanner therefore looks like a clean run for the default make apm-install path. Consider surfacing the scanner exit code (or at least a non-zero-but-visible signal) even outside --force. Confidence: Medium.
[Minor] Unused variable — scripts/apm-install.sh L10 sets REPO_ROOT but never uses it (ShellCheck SC2034). Drop it or wire it in. Confidence: High.

Summary
This PR adds agent skill security tooling and a cleaner APM install path for HyperShell.
It covers three related pieces:
/run-security-auditskillmake apm-install(install + Skillspector scan)Refs: HYPERSHELL-34
Background (APM & Skillspector)
APM (Agent Package Manager) is how this repo declares and installs shared agent skills from upstream packages (similar in spirit to a dependency manager, but for AI agent skills rather than runtime libraries).
Skillspector is a static security scanner for agent skills. It looks for risky patterns in skill code/scripts (for example unsafe subprocess usage). Findings can be suppressed via a baseline file so known false positives do not fail future scans.
What changed
1. Optional AI security harness skill (
/run-security-audit)Adds
skills/security/run-security-audit, which bootstraps Red Hat’s internal ai-security-harness on demand and runs threat modeling / secure code audit against this repo.Why this is not an APM dependency
The harness is intentionally not installed via APM for three reasons:
How it works instead
GITLAB_HOST=gitlab.cee.redhat.comGITLAB_APM_PAT=<PAT with read_repository on the harness project>Because the harness is no longer an APM dependency,
apm installcan run cleanly for everyone without worrying about GitLab auth.2.
make apm-install+ Skillspector baselineAdds a Makefile target so contributors do not need to know raw APM/Skillspector commands:
That runs
scripts/apm-install.sh, which:apm installuv/pipxinstall if missing).skillspector-baseline.yamlso known false positives / non-skill paths are ignoredAlso adds
make apm-auditfor the audit path declared inapm.yml.Open question: whether
apm-installshould later be folded into another Make target. For now it is standalone so the install/scan flow stays explicit and easy to discover.3. Selected ProdSec skills via APM
ProdSec maintains a large skill catalog. Pulling everything in was not practical, so only a small, clearly useful subset is declared in
apm.yml:go-securitytls-compliancedatabase-securityreact-securityhelm-chart-securitylinux-capabilitiesThese are available after
make apm-install, but they are not wired into other workflows yet. Review by people familiar with HyperShell’s code/security posture should happen before hooking them into CI, reconcile, or other automated flows.Test plan
