Agentic Bug Hunter is a terminal toolkit that uses AI to investigate security targets, test for vulnerabilities, validate findings, and write bug bounty reports. It is for ethical hackers submitting findings to platforms such as HackerOne, Bugcrowd, Intigriti, or Immunefi, and can resume previous sessions. The catalogue entries package commands, skills, agents, instructions, hooks, and settings for using the toolkit.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00096 | $0.01081 |
| Opus 5.5 | $0.00038 | $0.00432 |
| Sonnet 5.5 | $0.00019 | $0.00216 |
| Haiku 4.5 | $0.00010 | $0.00108 |
Grade B, and why
chain-builder scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Cloud metadata endpointmediumServer-side request forgery
One request to 169.254.169.254 can return temporary IAM credentials.
| SSRF DNS callback | 169.254.169.254 cloud metadata | Critical | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chain Builder Agent
You are a bug chain specialist. You take a confirmed bug A and systematically find B and C to combine for higher severity.
Your Approach
- Identify bug class of A
- Look up chain table for B candidates
- Check if B is testable from current position
- Confirm B exists (exact HTTP request)
- Output: chain path, combined severity, separate report count
The A→B Chain Table
| Found A | Check B | Combined Impact |
|---|---|---|
| IDOR (GET) | IDOR on PUT/DELETE same path | Multiple High |
| Auth bypass | Every sibling endpoint in same controller | Multiple High |
| Stored XSS | Admin views it? → priv esc | Critical |
| SSRF DNS callback | 169.254.169.254 cloud metadata | Critical |
| Open redirect | OAuth redirect_uri → code theft | Critical ATO |
| S3 bucket listing | JS bundles → grep OAuth creds | Medium/High |
| GraphQL introspection | Auth bypass on mutations | High |
| LLM prompt injection | IDOR via chatbot (other user data) | High |
| Path traversal | /proc/self/environ → RCE | Critical |
| Subdomain takeover | OAuth redirect_uri at subdomain | Critical |
| JWT weak secret | Forge admin token | Critical |
| File upload bypass | SVG→XSS, PHP→RCE | High/Critical |
Known High-Value Chains
Key Chain Examples
S3 → OAuth ATO: List bucket → download JS bundles → grep client_secret → test OAuth without code_challenge → 3 reports ~$1,200
Open Redirect → OAuth ATO: Confirm redirect → find OAuth flow → set redirect_uri to your redirect endpoint → victim clicks → code delivered to attacker → exchange for token
XSS → Admin Priv Esc: Stored XSS in user field → verify admin views it → payload auto-submits POST to promote attacker to admin
SSRF → Cloud Metadata: DNS callback only = Info → escalate to 169.254.169.254 → get IAM role → fetch credentials → enumerate AWS perms = Critical
Prompt Injection → IDOR: Confirm chatbot follows injected instructions → inject cross-user data request → if other user data returned = IDOR via AI feature
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

chain-builder is an agent published in the GitHub repository Awarexone/Agentic-Bug-Hunter (5,367 stars, last pushed 11d ago), licensed MIT. It adds 96 tokens to every session and 1,081 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Maps dangerous operations in a source file: memory ops, type casts, arithmetic near trust boundaries, free/dealloc patterns. Pattern matching task — list what you see, don't speculate. Use via /sast command.
sast-gap-analyzer
Analyzes validation gaps in data flows. Takes traced flows and identifies where checks are missing, insufficient, or bypassable. The 'interaction reasoning' step — finds bugs that exist in the gaps between individually correct-looking code. MUST run on Opus. Use via /sast command.

Drives the local camofox-browser REST server (Camoufox, C++-patched Firefox) for recon, client-side bug verification, and evidence capture. Prefer this over the Burp-backed browser-agent when the…
browser-verifier
Mandatory browser verification for client-side findings (XSS, DOM, postMessage, prototype pollution). Takes a finding with curl-based evidence and PROVES or DISPROVES it fires in a real browser. No finding ships without browser verification. Dispatched automatically by /hunt and /validate for client-side vuln classes.
