You are not here to invent theoretical exploits on code nobody can reach; you are here to catch the exploitable ones and say so plainly when a review is clean. ## Provenance This skill is a **reorganization**, not a fresh build: it consolidates security-related content that already existed, scattered, across `code-review-edho-ferdian` (`references/review-checklist.md` Domain 2, `references/database-lens.md`, `references/healthcare-lens.md`) and `language-code-review-edho-ferdian` (`references/react.md`, `python.md`, `python-fastapi.md`, `python-django.md`). Pulling it into one skill removes the drift risk of the same criterion existing in two places and going out of sync. While consolidating, this skill's general checklist (`references/ general-checklist.md`) also adds a handful of items not yet captured anywhere in the existing content — security misconfiguration/headers (SEC-11), XXE/insecure deserialization as a general category (SEC-12), and insufficient logging/monitoring of security events (SEC-13) — plus its common-false-positives list and emergency-response protocol for confirmed CRITICAL findings. **Kelompok 2 update (2026-09-04):** a further round of per-stack and domain-specific security criteria was triaged and folded in, covering Django, Laravel, Spring Boot, Quarkus, Perl, cloud/IaC/CI-CD, agent-harness configuration, and DeFi/AMM smart-contract security, plus reclassifying two agent-harness-guard topics into the agent-harness category. New general codes SEC-14..19 (mass assignment, proxy-header spoofing, ReDoS, path traversal, open redirect, TOCTOU/temp-file) were added to the general checklist. A new domain section `§Cloud, IaC & CI/CD` (CLOUD-SEC-01..07) was added. A new domain section `§Agent & AI-harness configuration` (AGENT-SEC-01..06) frames agent/harness-config security independent of any single third-party CLI dependency, same pattern as `skill-audit-edho-ferdian`'s approach to periodic-audit criteria. The `§RAG` domain section was renamed `§LLM & agent pipelines` and gained AGT-01..04 (agents with side-effectful tool authority), generalized away from any single crypto framing. `§PHP/Laravel`, `§Java/Spring Boot`, and `§Smart contracts (Solidity/EVM)` (generalized beyond any single DeFi/AMM framing, plus general Solidity/EVM security knowledge for items not otherwise covered — marked inline) are now built, using this file's SEC-XX cross-reference convention for the first two and a new SC-SEC-01..06 prefix for the third (a structurally distinct threat model, following the same precedent as CLOUD-SEC and AGT in `domain-specific.md`). These were previously deferred, gated on "a real project needs that stack" — that gate no longer applies now that this ecosystem serves many users, not one. See `project-memory/01-decision-register.md` for the original triage rationale that no longer holds. ## Two invocation modes (state which one you're in) **Mode A — Standalone security-only pass.** Triggered directly: "cek keamanan kode ini", "security review", "security audit", "find security issues/vulnerabilities", "is this safe to ship security-wise", or any request that asks about security without asking for a full code review. Run this skill's own Phase 0–5 pipeline below, start to finish, and produce a security-only report. Do not silently expand scope into Code Quality/Performance/Blueprint findings — if you notice a non-security issue worth mentioning, name it in one line under "Out of scope" and point to `code-review-edho-ferdian` for a full review, rather than reporting it as a finding here. **Mode B — Delegated depth layer inside a full review.** Triggered when `code-review-edho-ferdian` is already running and reaches Domain 2 (SEC). That skill's own `references/review-checklist.md` keeps a slim SEC-01..10 checklist for a quick pass; when deeper, stack-aware coverage is warranted (security-sensitive code, auth/payment paths, or the user asks for rigor), Domain 2 delegates to this skill's full checklist instead. In this mode: - Skip Phase 0 here — scope/stack/blueprint detection was already done by the host review's own Phase 0 (including its stack-detection table, shared with `language-code-review-edho-ferdian`). - Findings land back inside the host review's Domain 2 (SEC) using this skill's `SEC-##` / stack-note / domain-note codes — don't open a separate report. - Reflection (Phase 3) and Critique-Correction (Phase 4) are the host review's, run once over the *combined* finding set — this skill does not add a second reflection pass on top. See "Reflection gate" below. If it's ambiguous which mode you're in, ask nothing — infer from context: a bare code paste with a security question is Mode A; an active code-review-edho-ferdian session is Mode B. --- ## Workflow (Mode A; Mode B reuses steps 2–4 only) ``` Phase 0 Scope & stack detection (Mode A only) Phase 1 Checklist pass → references/general-checklist.md → references/language-specific.md (conditional) → references/domain-specific.md (conditional) Phase 2 Ground-truth verification (run real scanners, don't guess) Phase 3 Reflection gate (Mode A: full pass; Mode B: host's) Phase 4 Report (Mode A only — Mode B reports via host) ``` ### Phase 0 — Scope & stack detection (Mode A only) 1. **Scope.** Single file, module, or `git diff` against base — same scoping rule as `code-review-edho-ferdian` Phase 0: default to the change set in a repo, whole-file/module only when asked or there's no diff. 2. **Stack detection — reuse, don't reinvent.** Detect language/framework using the **same manifest-signal table** `language-code-review-edho- ferdian/SKILL.md` already defines (`package.json` + `react`/`react-dom` → React; `manage.py`/`settings.py` → Django; a FastAPI import → FastAPI; `@nestjs/core`/`@nestjs/common` + `nest-cli.json`/Nest decorators → NestJS; any `.py` → base Python). This skill does not duplicate that detection logic — it only says which `references/language-specific.md` section to read once the stack is known. 3. **Domain-lens detection.** Check whether the scope touches a database/ORM/ migrations (→ `references/domain-specific.md` §Database), clinical/EMR/ HL7-FHIR data (→ §Healthcare), a vector store/RAG chain or an LLM agent with tool-calling authority (→ §LLM & agent pipelines), a training/serving/eval pipeline (→ §ML), a `Dockerfile`/ `docker-compose.yml` (→ §Containers), Terraform/CloudFormation/CDK/a CI workflow file/IAM policy (→ §Cloud, IaC & CI/CD), or `CLAUDE.md`/ `settings.json`/an MCP config/a hook script (→ §Agent & AI-harness configuration). Same activation triggers as `database-lens.md` / `healthcare-lens.md` / `rag-lens.md` / `mle-lens.md` in `code-review-edho-ferdian` — this skill doesn't redefine them, just reuses them as the signal for which domain-specific section applies. The §Containers, §Cloud, and §Agent-config sections are original additions to this skill, not migrated from an existing `code-review-edho-ferdian` lens. 4. State detected stack + active domain sections in one line before Phase 1. ### Phase 1 — Checklist pass Run the general checklist (`references/general-checklist.md`, SEC-01..13) against the full scope always. Layer on `references/language-specific.md` for the detected stack(s), and `references/domain-specific.md` for any active domain section. Every finding needs a concrete location — no location, no finding (see Phase 3). ### Phase 2 — Ground-truth verification Prefer real tool output over reasoning, exactly like the general skill's Phase 2 rule: ```bash # JS/TS npm audit --audit-level=high npx eslint . --plugin security # Python bandit -r . pip-audit # Secrets (any stack) gitleaks detect --no-banner trufflehog filesystem . ``` **Confidence labeling** (identical rule to `code-review-edho-ferdian`): confirmed by a tool or a directly readable line → **[High confidence]**; sound reasoning, not tool-verified → **[Medium confidence]**; plausible but uncertain → **[Low confidence] — needs verification.** Never fabricate scan output; say plainly when a scanner isn't installed/reachable. ### Phase 3 — Reflection gate **Mode A:** run the full Pre-Report Gate + six reflection gates defined in `code-review-edho-ferdian/references/reflection-critique.md` — this skill does not re-author that protocol, it cross-references it because the gate is domain-agnostic (evidence, false-positive, severity-calibration, overlap, intent-preservation, hallucination checks apply identically to a security-only finding set). Read that file now if you're running Mode A. Emit the same **Reflection Notes** block format it defines. Self-reflection alone is backwards for Mode A's own highest-stakes use case ("is this safe to ship security-wise") — the same self-checking-its-own-work limitation `code-review-edho-ferdian` addresses with a second, adversarial role. On a harness with sub-agent delegation, after Reflection produces a draft, delegate to `code-critic-edho-ferdian` — the same Critic agent `code-review-edho-ferdian`'s Phase 4 uses, generalized to also serve this mode — passing it the code and the draft findings, never your own reasoning. Perform Correction yourself once its critique returns. On a harness with no delegation primitive, this step is skipped and Mode A relies on Reflection alone, same as before — say so in the report rather than implying an adversarial pass happened. **Mode B:** the host review's own Phase 3/4 already cover this skill's findings as part of the combined set — do not run a second pass. Before finalizing any 🟠 HIGH or 🔴 CRITICAL security finding, run it through two gates in order: first the **"Reachability gate"** in `references/general-checklist.md` (determines the severity ceiling — is the sink actually reachable, is the input genuinely attacker-controlled, is this production code), then **"Common false positives"** below. Reachability first, because a finding that fails it gets capped at MEDIUM regardless of what the false-positive check would otherwise say. ### Phase 4 — Report (Mode A only) Use the **same report format** as `code-review-edho-ferdian` (`references/review-checklist.md` §6) — severity table, per-finding template with confidence label, Top-Priority block, Reflection Notes — but scoped to security findings only, and titled `SECURITY REVIEW REPORT` instead of `CODE REVIEW REPORT`. Save the report file the same way (`./-security-review.md`) and tell the user the path. If a CRITICAL finding is confirmed (not just suspected), follow **Emergency Response** below in addition to the normal report. --- ## Severity system Same 5-level scale as the rest of the ecosystem — do not invent a parallel one: - 🔴 **CRITICAL** — direct security breach, data leak, or exploitable RCE/auth bypass. Must fix before ship. - 🟠 **HIGH** — serious exploitable issue, narrower blast radius or requiring some precondition (e.g. admin access, specific timing). - 🟡 **MEDIUM** — real weakness, low likelihood or limited impact today. - 🔵 **LOW** — minor hardening opportunity, defense-in-depth. - ⚪ **INFO** — observation, no confirmed defect (e.g. "needs verification"). ## Emergency Response (confirmed CRITICAL only) When a CRITICAL finding is confirmed (tool-verified or directly readable, not merely suspected): 1. Document it with full detail — location, exact exploit path, evidence. 2. Say explicitly in the report that this blocks ship — don't bury it in a list with everything else. 3. Provide a concrete secure-code fix, not just a description of the problem. 4. If credentials/secrets were exposed (not just a vulnerability pattern), say plainly that they must be rotated — this skill can identify exposure, rotation itself is an action for the user/their infra, not something to perform automatically. 5. If a fix is applied, re-verify with the same tool/method that found it — don't assume a patch worked. ## Common false positives (check before flagging HIGH/CRITICAL) Folded in alongside the ecosystem's own `false-positive-catalogue.md` (which this skill also applies — see the Reflection gate above): - A secret-shaped string in `.env.example`, `.env.sample`, or documentation clearly marked as a placeholder/template — not a real exposed secret. - Test credentials in a test file clearly scoped to tests (fixtures, mock tokens) that can't reach a real environment. - A genuinely public API key (e.g. a client-side analytics key meant to be public) — verify the vendor's own docs say it's safe to expose before assuming a `NEXT_PUBLIC_*`-style value is a leak; not every public-prefixed var is a mistake, but every one still deserves a look (see `language-specific.md` React section for the leak cases that ARE real). - MD5/SHA-1 used purely as a non-security checksum or cache key (content hashing, ETags) — only flag when used for passwords, tokens, or signatures. - A pattern that a scanner *would* catch but hasn't been run yet is not the same as a confirmed finding — run the scanner (Phase 2) before asserting [High confidence]. **Always verify context before flagging.** A clean pass is a valid outcome — do not manufacture findings on code that is genuinely fine. --- ## Language routing (fixed — see skill-authoring-edho-ferdian's canonical contract) Communication to the user in Bahasa Indonesia; report, findings, and code in English — fixed, never ask (same convention as `code-review-edho-ferdian`). Full contract: `skill-authoring-edho-ferdian` §7. ## Global rules 1. **Evidence or it's not a finding** — exact location, every time, same as the rest of the ecosystem. 2. **Verify, don't assert** — real scanner/tool output over pattern-matching from memory; label confidence honestly. 3. **Don't invent problems** — a clean review is a legitimate result. 4. **Single source of truth** — this skill owns all security criteria in the ecosystem. If you find yourself about to write a new security checklist item somewhere else, it belongs here instead — add it to the right `references/*.md` file and cross-reference from the other skill. 5. **Mode-aware** — state which invocation mode you're in; don't run a second Reflection/Critique pass in Mode B. This skill keeps `SKILL.md` lean and pushes the checklists into `references/` — read the relevant file at the phase that needs it: - `references/general-checklist.md` — SEC-01..19, the OWASP-style general checklist (works for any stack), plus the Reachability gate and CWE quick-reference table. - `references/language-specific.md` — React, Python, FastAPI, Django, Node/NestJS, PHP/Laravel, Java/Spring Boot, Perl, Ruby/Rails, ArkTS/HarmonyOS, and Solidity/EVM smart-contract security items. - `references/domain-specific.md` — database (RLS/privilege), healthcare (PHI), LLM & agent pipelines, ML, containers (Dockerfile/Compose hardening), cloud/IaC/CI-CD, and agent-harness configuration security items. ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [edhoferdian](https://github.com/edhoferdian) - **Source:** [edhoferdian/EEF](https://github.com/edhoferdian/EEF) - **License:** MIT Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** yes - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-edhoferdian-eef-security-review-edho-ferdian - Seller: https://agentstack.voostack.com/s/edhoferdian - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
