--- name: remediating-with-aws-security-agent description: >- Pull AWS Security Agent findings (penetration tests and code reviews) and drive remediation. Use this whenever the user mentions Security Agent, security findings, pentest or penetration test results, code review findings, vulnerabilities found in their AWS account, "what did the security scan find", remediating or triaging security risks, or wants to start fixing reported vulnerabilities — even if they don't name the service explicitly. Trigger it for phrases like "get my security findings", "what vulnerabilities do we have", "let's fix the pentest results", or "triage the security report". The skill discovers scans, exports findings to a gitignored local directory (so sensitive exploit detail is never committed), produces a prioritized triage summary, and offers to start fixing the highest-risk issues. --- # Security Agent Remediation AWS Security Agent is a frontier agent that runs on-demand penetration tests and code reviews against a customer's applications and reports verified security risks. This skill takes you from "I have findings somewhere in AWS" to "I'm actively fixing the most important ones," while keeping the sensitive exploit detail out of source control. The flow has four stages, and they matter in order: 1. **Discover** which scans exist and how the account is configured (live, read-only). 2. **Export** the findings to a local gitignored directory. 3. **Triage** the findings into a prioritized, human-readable plan. 4. **Remediate** by offering to fix the highest-risk issues. ## Why the ordering and the guardrails matter Findings contain working attack scripts, reproduction steps, file paths, and sometimes leaked secrets or environment details. If that lands in a Git repo, a customer can accidentally commit and publish a step-by-step exploit for their own production system. So the non-negotiable rule is: **findings are written only to `.security-agent/`, and that path is gitignored before anything is written.** ## Stage 1: Discover scans (live, read-only) Find out what the account has. All commands are read-only `list-*` operations. AWS Security Agent organizes data as a hierarchy — work down it: ``` Application (account + Region) └── Agent Space (workspace for design review, code review, and pentests) ├── Penetration test → Pentest job → Findings └── Code review → Code review job → Findings ``` Run these to orient yourself and show the user what exists: ```bash aws securityagent list-agent-spaces aws securityagent list-pentests --agent-space-id aws securityagent list-code-reviews --agent-space-id aws securityagent list-pentest-jobs-for-pentest --agent-space-id --pentest-id aws securityagent list-code-review-jobs-for-code-review --agent-space-id --code-review-id ``` Job `status` is one of `IN_PROGRESS`, `STOPPING`, `STOPPED`, `FAILED`, `COMPLETED`. Only `COMPLETED` jobs have a stable, full set of findings. ### Match the codebase to a scan, then confirm Agent spaces, pentests, and code reviews are named after the application they target. Before asking the user to pick from a raw list, make an informed guess about which scan corresponds to *this* repository — the user is working in a codebase for a reason, and the relevant findings are almost always for the app in front of them. Infer the app identity from the workspace using cheap, high-signal sources: - The repository / root directory name and the Git remote URL (`git remote -v`). - Project manifests and their `name`/`description` (`package.json`, `pyproject.toml`, `*.csproj`, `go.mod`, `Cargo.toml`). - README titles, product/steering docs, and any obvious product or company name. - Distinctive frameworks or domains that match a scan title. Compare those signals against the agent space / scan names (case-insensitive, allow partial and fuzzy matches). Then **always confirm before exporting** — present your best guess and your reasoning, and let the user correct it: > "This repo looks like **``** (from ``), which matches the **** agent > space. Use that, or pick another? [Other Agent Space names, ...]" If nothing matches with reasonable confidence, say so plainly and show the full list rather than forcing a wrong guess. Never export from a guessed scan without the user's confirmation. ## Stage 2: Export findings to `.security-agent/` (gitignored) Pull findings using AWS CLI commands. Write everything into `.security-agent/` in the repo — never to chat or stdout — because findings include working attack scripts, reproduction steps, and sometimes leaked secrets. ### 1. Lock down the output directory before pulling anything ```bash mkdir -p .security-agent echo '*' > .security-agent/.gitignore ``` ### 2. Resolve the latest COMPLETED job You should already have the `agentSpaceId` and the pentest/code-review id from Stage 1. List jobs for the chosen scan: ```bash # Pentest jobs: aws securityagent list-pentest-jobs-for-pentest \ --agent-space-id --pentest-id # Code review jobs: aws securityagent list-code-review-jobs-for-code-review \ --agent-space-id --code-review-id ``` Paginate by passing `--next-token` from the previous response until absent. Filter the job summaries to `status == "COMPLETED"`. If none are COMPLETED, stop and tell the user "No completed jobs found. Please wait for a job to complete or check job statuses." Otherwise, pick the COMPLETED job with the greatest `createdAt` timestamp. ### 3. List finding summaries and filter by confidence ```bash # Pentest findings: aws securityagent list-findings \ --agent-space-id --pentest-job-id # Code review findings: aws securityagent list-findings \ --agent-space-id --code-review-job-id ``` Paginate on `--next-token` until exhausted. Confidence values from weakest to strongest: `FALSE_POSITIVE`, `UNCONFIRMED`, `LOW`, `MEDIUM`, `HIGH`. **Keep only `HIGH` and `MEDIUM` by default.** Widen only when the user explicitly asks. ### 4. Fetch full detail in batches of 25 `batch-get-findings` accepts at most 25 ids per call. Chunk the filtered finding ids into groups of 25: ```bash aws securityagent batch-get-findings \ --agent-space-id \ --finding-ids ... ``` Tag each returned finding with its source (`pentest` or `code-review`) before writing, so triage in Stage 3 can tell them apart. ### 5. Write findings into `.security-agent/` Group findings by job id. For each job, write a full markdown report to `.security-agent/findings_.md` with ALL fields returned by the API (findingId, name, description, riskLevel, riskType, confidence, status, codeLocations, remediationCode, and any other fields). Do not leave off any fields. ### Edge cases - **No agent space, scan, or COMPLETED job** — stop and surface that to the user rather than retrying. - **Credentials or service unavailable** — confirm with `aws sts get-caller-identity` and check the Region (default `us-east-1`; Security Agent is regional). - **Don't paste finding contents into chat** beyond short titles and counts. The detail belongs in the gitignored files. ## Stage 3: Triage into a prioritized plan Rank by risk, because remediation time is finite and a CRITICAL unauthenticated RCE outranks a LOW informational finding every time. Read the exported `findings_*.md` files from `.security-agent/` and sort them deterministically. ### Ranking rules Sort ascending by this composite key (lower wins, i.e. more urgent first): 1. **Risk level**, in this order: `CRITICAL` (0) → `HIGH` (1) → `MEDIUM` (2) → `LOW` (3) → `INFORMATIONAL` (4) → `UNKNOWN` / missing (5). 2. **Risk score**, highest first. `riskScore` is a numeric string on pentest findings (e.g. `"10.0"`), often absent on code-review findings — treat missing as the lowest possible score so it sorts after scored findings of the same level. 3. **Confidence**, in this order: `HIGH` (0) → `MEDIUM` (1) → `LOW` (2) → `UNCONFIRMED` (3) → `FALSE_POSITIVE` (4). Also compute a severity-count summary across all findings (e.g. `2 CRITICAL · 5 HIGH · 3 MEDIUM`) for the header of the report. ### Pulling the code location For each finding, derive a single short `location` string: - If `filePath` is set, use it as-is. - Otherwise, take `codeLocations[0]`. Strip the scanner's sandbox prefix from `filePath` (everything up to and including that marker) so the path is repo-relative; if that marker isn't present, fall back to the basename. Append `:` when present. - If neither is available (typical for some pentest findings), leave it blank and describe the affected endpoint or attack chain in the impact line instead. ### Summary format Write a compact summary for the user: ``` ## Security Agent triage — findings exported (

) · confidence: · severity: ### Priority order 1. [CRITICAL · score 10.0 · HIGH confidence] - Type: · Source: - Where: - Impact: 2. [HIGH · ...] ... ### Recommended remediation order ``` If more than ~10 findings, show the top N in detail and summarize the rest as a count by severity at the bottom. ### What to keep out of chat The full `description`, `reasoning`, and `attackScript` stay in the gitignored files — they contain working exploit detail. In the chat summary keep impact lines to one line each, in plain language. Code-review findings usually carry a `filePath`/location and a `suggestedFix`; call those out since they map directly to repo changes. Pentest findings describe endpoints and attack chains; map them to the responsible code where you can. Look for findings that corroborate each other (a pentest and a code review flagging the same root cause) — those are strong signals for what to fix first. ## Stage 4: Offer to remediate After presenting the triage, offer to start fixing — don't silently begin editing code. Ask the user something like: "Want me to start fixing the top finding(s)? I'd recommend starting with #1 ()." If they agree, work top-down by priority: 1. Read the finding detail from the gitignored export file (location, description, suggested fix). 2. Open the affected file and apply the fix via the editor. 3. Report one line per fix: "Fixed {name} in `{filePath}:{lineStart}`." If the user wants to handle several findings, fix one at a time (or one cluster of related findings) so each change stays reviewable, and proceed in the priority order from Stage 3. ## Notes and edge cases - **No completed jobs**: a scan may still be `IN_PROGRESS`. Tell the user; offer to re-check later rather than exporting a partial job. - **Re-running**: each run overwrites the files for that job id. The directory is safe to delete; it only holds exported copies, not source-of-truth data. - **Multiple accounts/Regions**: findings are Region-scoped. If the user expected results and got none, confirm the region matches where Security Agent is configured. - **Data handling**: treat exported findings as sensitive. They are copies of verified exploits against the user's own systems.
