bug-hunting

bug-hunting is a skill for Claude Code, Codex from Roshu18/bearstrike-ai. It costs 16 tokens per session (274 once invoked), scanned A, original, MIT.

An end-to-end workflow for authorized bug-bounty testing, from discovering systems to confirming vulnerabilities and writing a report. A bug bounty is a program where organizations allow security researchers to report flaws under set rules.

In plain words
What is it for?
It is for mapping hosts, finding endpoints, testing authorization and other likely weaknesses, manually confirming impact, and producing a report.
Why use it?
It keeps testing within the allowed scope, reduces noisy scanning, and requires evidence before reporting a suspected issue.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

bug-hunting scanned grade A with 0 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 10d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

bug-hunting

Use this flow for authorized bug bounty targets.

State machine

RECON -> ENUM -> VULN -> VERIFY -> REPORT

Rules

  • Stay in scope at every step.
  • Stop noisy scans when WAF is detected and switch to low-rate mode.
  • Confirm findings manually before report generation.
  1. recon skill to map hosts and services.
  2. pentest-tools skill to choose matching tools per target type.
  3. exploitation skill only after strong signals.
  4. reporting skill to produce final markdown package.

Bug-hunt loop (efficient mode)

Use this loop to reduce noise and token burn:

  1. Build endpoint shortlist by business impact.
  2. Test authorization boundaries first.
  3. Validate one strong signal to completion.
  4. Expand only if evidence quality remains high.

Where bugs are often found

Focus checks on:

  • ID fields in REST/JSON APIs
  • GraphQL object queries and mutations
  • Mobile/web API parity gaps
  • Multi-step flows (cart -> payment -> refund)
  • Export/report endpoints leaking cross-tenant data

Quality gate

Do not continue to next hypothesis until current one has:

  • baseline response,
  • altered request response,
  • clear impact statement.
Changes

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.

bug-hunting is a skill published in the GitHub repository Roshu18/bearstrike-ai (4 stars, last pushed 5mo ago), licensed MIT. It adds 16 tokens to every session and 274 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
