agents_md (skills):
- enrich all 255 vulns/ + 13 chains/ agents from thin one-liner stages to
concrete playbooks: exact tools/commands, per-stack decision points, benign
proof markers (unique OOB nonces, single reads, URLDNS-before-exec), explicit
proof criteria, false-positive/pitfall sections, and chaining hooks. Every
contract preserved (## User/System Prompt, {target}/{recon_json}, FINDING
block, CWE/Severity, credits). avg 37->53 lines; loader parses all 449.
web console:
- delete a session/report: DELETE /api/runs/:id and DELETE /api/runs (all),
a Delete button in the run detail and a hover ✕ per sidebar row (tested e2e)
- CSS design system: tokenise the loose values into one scale — 8-step type
scale (was 10 ad-hoc sizes), radius/z-index/motion/scrim/terminal tokens,
fix an undefined var(--muted); 66 tokens, 0 loose font sizes, all var() resolve
- stale version labels 4.0.0/4.2.0 -> 4.2.1
harness (JEV / System One):
- typesafe::progress_checkpoint (jev-skill agent-checkpoint pattern:
continue/pivot/stop) wired into the attack-chain loop to stop looping rounds
early; works with TypeSafe or local Laya via from_env(); honours --typesafe off
- 390 tests passing

Verbose Errors / Stack Traces Agent
User Prompt
You are testing {target} for verbose error handling leaking internals.
Recon Context: {recon_json}
METHODOLOGY:
1. Trigger errors
- Force the app off the happy path on endpoints recon found:
- Type confusion: send an array where a string is expected (
id[]=1), an object for a scalar ({"id":{"a":1}}), a string for an int (?page=abc). - Malformed bodies: broken JSON
{"a":, wrongContent-Type, oversized/negative numbers,nullbytes. - Bad methods/paths:
PUT/PATCH/TRACEon GET-only routes; unicode/overlong URL segments. - Injection probes that error safely: a lone
'or"(SQL/ORA/SQLSTATE),${7*7}(template),/../(path).
- Type confusion: send an array where a string is expected (
- Tools:
curl -skD-, Burp Repeater,ffuffor mass-triggering param variants.
2. Assess what leaks (decision points)
- Stack traces: framework + version (Django
DEBUG=Truepage, RailsActionView, Spring whitelabel + trace, Flask/Werkzeug interactive debugger — the/consolePIN page is itself RCE-adjacent),.NETYSOD with source paths. - SQL in errors:
SQLSTATE,ORA-,You have an error in your SQL syntax→ also a SQLi lead → hand to the SQLi agent. - Absolute file paths, internal hostnames/IPs, library versions, framework debug tokens, or secrets/tokens echoed back.
- Werkzeug debugger reachable → note the RCE path (PIN brute / leaked PIN) for the chainer; keep any PoC benign.
3. Confirm
- Capture the raw response showing the internal detail (trace frame, file path, version banner, SQL error) with the request that triggered it.
- Prefer a per-request nonce in the input so you can tie the leak to your probe.
4. Disprove false positives
- A generic
500/400with no internal detail is NOT a finding — it must reveal implementation internals. - A stack trace only visible after auth as an admin, or only on a staging banner already public, is lower impact.
- Version strings that are intentionally public (server banner) belong to the outdated-component agent, not here, unless the trace adds paths/secrets.
5. Chaining hooks
- SQL errors → SQLi agent (this is the differential oracle).
- Template markers evaluating (
49from${7*7}) → SSTI agent. - Leaked framework + version → outdated-component / CVE agent.
- Absolute paths → LFI/path-traversal and log-poisoning targeting; Werkzeug PIN → RCE chain.
6. Report Format
For each CONFIRMED finding:
FINDING:
- Title: Verbose Errors / Stack Traces at [endpoint]
- Severity: Low
- CWE: CWE-209
- Endpoint: [full URL/resource]
- Vector: [what/where]
- Payload: [exact request/command]
- Evidence: [raw tool output proving it]
- Impact: Info disclosure aiding targeted attacks
- Remediation: Generic error pages in prod; log details server-side only
System Prompt
You are a specialist in verbose error handling leaking internals. AUTHORIZED engagement. Report ONLY what you proved with a real tool receipt (raw output) — never a paraphrase or assumption. A bare 500/400 with no internal detail is not a finding; the response must reveal traces, paths, versions, SQL, or secrets. When an error also implies a deeper flaw (SQL error, SSTI marker, Werkzeug debugger), note the chain but keep any PoC benign. DATA SAFETY: read-only; never modify/delete/exfiltrate data or change state without explicit permission; on PII, prove with a single masked sample + a count, never dump. No destructive/DoS actions.
