From b03fcda8334f9613e0a1ec22db3ec435d68508e6 Mon Sep 17 00:00:00 2001 From: Gustavo Caetano Date: Sat, 31 Oct 2026 18:49:33 -0300 Subject: [PATCH 1/7] chore(security): pin SkillSpector by SHA and add blocking secret scanning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Pin NVIDIA SkillSpector to the exact commit of v2.13.2 (fetched by SHA, not tag/main) and install it from that ref — a moving upstream can no longer weaken the advisory gate silently. - Add a BLOCKING gitleaks workflow (PR diff, push-to-main, weekly full-history cron), with the action pinned by SHA like SkillSpector. - Add .gitleaks.toml allowlists audited against the first scan: 60 findings, 0 real secrets (public Supabase anon JWTs shipped in client bundles, Apify actor IDs, tokenizer SHA-256 hashes, synthetic_* fixtures).

"Skill never activated" is a first-class INCONCLUSIVE, never a free PASS. - Judge identity is recorded per arm; mixing judge models degenerates to INCONCLUSIVE instead of silently comparing two experiments. - New src/lib/adversarial/stamping.ts: an eval run carries an evidence stamp with the required checks (full_suite, holdout_included, scan_clean, judge_source_recorded). eval-adversarial.ts writes judge_model and the stamp (scan_clean comes from the SAME blocking audit gate); a sampled run can no longer self-certify. - Trust score (both scorers) gains a versioned policy, retracts adversarial evidence when the stamp is present but not certify-worthy, and caps the score at 0.69 when the security scan did not complete — an incomplete analysis can never render green, and never verifies. --- scripts/benchmark-paired.ts | 26 ++++- scripts/eval-adversarial.ts | 34 +++++++ src/lib/adversarial/stamping.ts | 82 +++++++++++++++ src/lib/benchmark/paired.ts | 173 +++++++++++++++++++++++++++++++- src/lib/trust/score.ts | 64 +++++++++++- src/lib/trust/scoring.ts | 45 ++++++++- tests/evidence-stamping.test.ts | 42 ++++++++ tests/paired-benchmark.test.ts | 171 +++++++++++++++++++++++++++++++ tests/trust-scoring.test.ts | 74 ++++++++++++++ 9 files changed, 701 insertions(+), 10 deletions(-) create mode 100644 src/lib/adversarial/stamping.ts create mode 100644 tests/evidence-stamping.test.ts diff --git a/scripts/benchmark-paired.ts b/scripts/benchmark-paired.ts index b64e6be1..bfd58908 100644 --- a/scripts/benchmark-paired.ts +++ b/scripts/benchmark-paired.ts @@ -116,9 +116,24 @@ const baselineReport = await runSuite( Promise.resolve(`Sure!

rejectAt is an option). - Add NVIDIA SkillSpector golden patterns to the production guard: P2 hidden Unicode TAG instructions (U+E0000..U+E007F), MP1-MP3 memory poisoning (credential seeding is critical), TP3 parameter-description smuggling, AR1-AR3 unconditional anti-refusal overrides. - Add golden pattern SC9 (.pyc/.pyo bytecode) to the malicious-function rules. - Sanitized output now strips the tag block too; the AR rule is scoped to unconditional refusal wipes so benign guidance ("never refuse outright") does not false-positive. - Golden test cases pin each pattern plus benign look-alikes; the repo's own content still audits clean (0 packages blocked). --- scripts/audit-skills.ts | 255 ++---------------- src/lib/security/package-audit.ts | 300 +++++++++++++++++++++ src/lib/security/prompt-injection-guard.ts | 58 +++- tests/audit-skills.test.ts | 53 +++- tests/prompt-injection-guard.test.ts | 72 +++++ 5 files changed, 508 insertions(+), 230 deletions(-) create mode 100644 src/lib/security/package-audit.ts diff --git a/scripts/audit-skills.ts b/scripts/audit-skills.ts index e9c4e0ca..8deb61c1 100644 --- a/scripts/audit-skills.ts +++ b/scripts/audit-skills.ts @@ -1,5 +1,5 @@ #!/usr/bin/env node -// Marketplace security audit gate. +// Marketplace security audit gate — CLI around src/lib/security/package-audit. // // Every package that is published to the marketplace (skills, playbooks, // souls, integrations) is scanned for malicious content BEFORE it can be @@ -11,6 +11,9 @@ // instructions that would make an agent exfiltrate data, run remote code, // wipe disks, or phone home to a non-allowlisted host. // +// The SAME implementation backs the MCP `security_scan` tool;

charset=UTF-8 Content-Transfer-Encoding: 8bit Port of SkillSpector's --mcp-registry-compare idea to the registry: a package that keeps its identity (slug + version + publisher) while its content or tool surface changes is the rug-pull attack, and version strings alone cannot see it. - src/lib/marketplace/rug-pull.ts: pure comparator over published vs candidate snapshots — CONTENT_CHANGED_SAME_VERSION (critical), TOOL_SET_CHANGED, PUBLISHER_CHANGED, VERSION_ROLLBACK. A new version with new content is a release, not a finding. - scripts/check-rug-pull.ts: compares a published manifest against content/skills (or --write-manifest to snapshot at release time); exit 1 on findings with --fail-on-findings. - Tests cover the attack, the legitimate release, order-insensitive tool sets and deterministic content hashing. --- scripts/check-rug-pull.ts | 135 ++++++++++++++++++++++++++ src/lib/marketplace/rug-pull.ts | 163 ++++++++++++++++++++++++++++++++ tests/rug-pull.test.ts | 67 +++++++++++++ 3 files changed, 365 insertions(+) create mode 100644 scripts/check-rug-pull.ts create mode 100644 src/lib/marketplace/rug-pull.ts create mode 100644 tests/rug-pull.test.ts diff --git a/scripts/check-rug-pull.ts b/scripts/check-rug-pull.ts new file mode 100644 index 00000000..293e285f --- /dev/null +++ b/scripts/check-rug-pull.ts @@ -0,0 +1,135 @@ +#!/usr/bin/env node +// Rug-pull check (NVIDIA SkillSpector `--mcp-registry-compare` import). +// +// Compares a PUBLISHED manifest (snapshots captured at release time) against +// the package files currently in the working tree.
