quickstart

Get started with vulnerability review through a guided practice target, from threat modeling to scanning and triage. Ask questions about the pipeline and receive answers grounded in its documentation and source, with references and a next command.

OriginalShow the original description

The front door for this repo. With no argument: a 30-second intro, then an offer to walk you through your first run on the canary target. With a question: answers it from this repo's own docs and source, cites where it looked, and hands you the next command. Use for "how do I…", "why does…", "where is…", "can this…", or just "/quickstart" to get oriented.

Review the instructions the agent will receive before you install.

/quickstart

Two modes, picked by whether $ARGUMENTS is empty.

  • Empty → Intro mode. Short orientation, then offer the guided first run.
  • Non-empty → Help mode. Treat $ARGUMENTS as the operator's question.

Intro mode

Keep it short and a little warm; this is the first thing a new operator sees.

Say roughly:

Welcome! This repo takes you from finding your first vulnerability to patching at scale, using a set of Claude Code skills and an autonomous pipeline. Two ways in: interactive skills (no setup, safe, start here) and the autonomous pipeline (Docker, scales to hundreds of parallel agents).

The ramp-up:

| Day 1 | Threat-model + first static scan + triage | | Day 2 | Run the reference pipeline (C/C++) | | Day 3-4 | Customize it for your stack | | Week 2 | Autonomous scanning, triage, and patching |

Day-1 goal: threat-model, scan, and triage the bundled canary target. Most teams get there before lunch.

Remind them to export CLAUDE_CODE_SUBAGENT_MODEL=<model-id> so subagents use the same model as the session.

Then AskUserQuestion with three options:

  1. Walk me through Day 1 on the canary (~10 min) → run "Guided first run" below.
  2. I have a question → ask what it is, then switch to Help mode.
  3. I'll read the README → point at README.md Step 1 and stop.

Guided first run

Runs the three Step-1 skills on targets/canary, pausing after each to show what landed on disk. These only read/write files in the repo; no sandbox needed.

  1. /threat-model bootstrap targets/canary via Task. When done, open THREAT_MODEL.md, show the focus areas, explain in 2-3 sentences how this steers the scan.
  2. /vuln-scan targets/canary via Task. When done, open targets/canary/VULN-FINDINGS.md, summarize the count and top 2-3 findings, point at VULN-FINDINGS.json.
  3. /triage targets/canary/VULN-FINDINGS.json via Task. When done, open TRIAGE.md, explain what changed vs. raw findings (verified, deduped, re-ranked).

Pause for the operator between each (AskUserQuestion); don't barrel through. Close with a one-line recap of the three artifacts on disk, then point at README Step 2 for the execution-verified pipeline. Never run vuln-pipeline or anything that executes target code here; that's Step 2 and needs Docker + a sandbox.


Help mode

Answer the operator's question using this repo as ground truth: README, docs/*.md, harness/*.py, dnr_harness/*.py, targets/*/config.yaml, .claude/skills/*. Don't answer from general knowledge when the repo has a specific answer.

Answer format

  1. Direct answer in 2-5 sentences.
  2. > source: the file(s) and section you used.
  3. Next action: one copy-pasteable command or skill invocation, if one applies. If none does, say so.
  4. If the question is ambiguous, ask one clarifying question; don't guess.

Constraints

  • Never fabricate CLI flags or file paths. If unsure, Grep for it in harness/cli.py or the target configs and quote what you find.
  • If the repo doesn't answer the question, say so plainly and suggest the operator open a GitHub issue on this repo.
  • Keep the Q&A dry and cited. Save the warmth for Intro mode.

customize

FreeSummary

Adapt a C/C++ vulnerability pipeline to another language, target, or detection method. The workflow gathers requirements, proposes file changes for approval, updates the implementation, and validates it against a test target containing known bugs.

  • Adapt the pipeline for web application vulnerabilities
  • Plan a port for smart contract auditing
  • Change detection signals and report criteria

dnr-hunt

FreeSummary

Hunt for signs of compromise in web and application logs without an initial alert. Establish normal activity, record investigative hypotheses, check source code, and reproduce issues locally before producing incident records and a report.

  • Tracing related activity across application logs
  • Distinguishing attack attempts from successful exploitation
