Subject: [PATCH 01/10] feat(poc-gen): rewrite POC prompt to prevent safety
 refusals; extract examples
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rewrites buildPOCPrompt() in agent-executor.ts to remove all patterns
that Claude Sonnet identifies as prompt injection: invented terminology
(RML), persona injection, ALL-CAPS emphasis, and claimed authorization
assertions.  The new prompt uses neutral "security test case" framing,
is ~50 template lines (down from ~340), and keeps the JSON output schema
identical so parsePocResponse() requires no changes.

Extracts all 7 inline examples to src/agents/poc-examples.ts and adds
selectPocExamples() which returns at most 2 relevant examples per call,
or an empty array when no category matches (avoids sending misleading
examples that degrade output quality).

Reviewer feedback addressed:
- WARNING poc-examples.ts: fallback changed from slice(0,maxCount) to
  empty array on no-match — irrelevant examples degrade output quality
- WARNING poc-examples.ts: substring matching semantics documented in
  JSDoc comment above selectPocExamples()
- INFO poc-examples.ts: PocOutput.validated typed as boolean (not false
  literal); PocExample.example: PocOutput keeps the type reusable
- INFO poc-examples.ts: POC_EXAMPLES exported as readonly with
  Object.freeze() to prevent mutation in long-running processes
- INFO agent-executor.ts: existing parseResponse() already handles
  leading prose (extractTopLevelJson) and fences (steps 1-2); no change
  needed to poc-generator.ts

 ## Guidelines
-- Trace data flow from attacker-controlled input to the vulnerable code path
-- Exploitation dependencies: ${deps}
-- Reachability conditions: ${reachability}
-- Use exact identifiers from the source: function names, endpoint paths, parameter names, types
-- Choose the language that matches the vulnerability type (HTML for browser bugs, Python/JS for web backends, C for memory-safety, Bash for command injection, etc.)
-- Setup instructions must be complete enough for a tester who has not seen the code before
+
+- Trace data flow from attacker input to the vulnerable code path
+- Address exploitation dependencies: ${deps}
+- Address reachability conditions: ${reachability}
+- Choose a test case language appropriate for the vulnerability type
+- Include complete setup instructions — assume the tester is unfamiliar with the codebase
+- Use exact identifiers from the code (function names, endpoint paths, parameter names)
+- Confirm each dependency and reachability condition in the prerequisitesHandled fields

- selectPocExamples: remove silent fallback to unrelated examples; now returns
  empty array when no category matches (per reviewer feedback that irrelevant
  examples degrade model output quality). Adds console.warn so degraded prompts
  are visible in production logs rather than silently producing worse POCs.

- agent-executor buildPOCPrompt: strip `validated` from serialized example JSON
  before injecting into the prompt. Prevents the model from cargo-culting
  `validated: false` as a required literal value rather than treating it as a
  runtime sentinel set by the validation step.

- Update JSDoc on selectPocExamples to accurately describe the no-fallback
  behavior and the observability rationale.

- selectPocExamples now returns empty array (not fallback) when no
  category matches, emitting console.warn so degraded prompts are
  observable in production logs
- Omit `validated` field from serialized examples injected into the
  prompt; prevents LLM from cargo-culting `validated: false` as a

- Updated JSDoc to document the no-fallback behavior and its rationale
- Added per-example label (### Example N (language)) to examples section

 ## Guidelines
-
-- Trace data flow from attacker input to the vulnerable code path
-- Address exploitation dependencies: ${deps}
-- Address reachability conditions: ${reachability}
-- Choose a test case language appropriate for the vulnerability type
-- Include complete setup instructions — assume the tester is unfamiliar with the codebase
-- Use exact identifiers from the code (function names, endpoint paths, parameter names)
-- Confirm each dependency and reachability condition in the prerequisitesHandled fields
+- Trace data flow from attacker-controlled input to the vulnerable code path
+- Exploitation dependencies: ${deps}
+- Reachability conditions: ${reachability}
+- Use exact identifiers from the source: function names, endpoint paths, parameter names, types
+- Choose the language that matches the vulnerability type (HTML for browser bugs, Python/JS for web backends, C for memory-safety, Bash for command injection, etc.)
+- Setup instructions must be complete enough for a tester who has not seen the code before

- selectPocExamples now returns empty array (no fallback) when no category
  matches the vulnerability type, and emits console.warn with the unmatched
  type so degraded prompts are observable in production logs (W1)
- Destructure validated out of e.example before JSON.stringify so the LLM
  does not cargo-cult "validated: false" from examples (W2)
- Remove curl from the language enum; http covers the same use case and no
  downstream code switches on the "curl" value (I1)
- Update selectPocExamples JSDoc to document the no-fallback behavior (I3)

Subject: [PATCH 05/10] fix(poc-examples): remove trailing whitespace from
 Python command-injection example

Cosmetic: two trailing spaces at end of last print() call in the Python
command-injection POC would be embedded as literal whitespace when the
code string is rendered, which could produce invalid Python indentation.

Subject: [PATCH 07/10] fix(poc-examples): address WARNING findings from PR
 review

- Add console.warn in selectPocExamples when no category matches,
  so silent fallback to generic examples is observable in production logs
- Destructure `validated` out of example objects before JSON.stringify
  in buildPocPrompt, preventing the LLM from cargo-culting `validated: false`
  from examples into its output

  emit console.warn so degraded prompts are observable in production logs
- buildPocPrompt: destructure validated out of e.example before JSON.stringify

Subject: [PATCH 09/10] fix(poc-gen): address review warnings for
 selectPocExamples and validated field

- selectPocExamples now returns [] when no category matches (instead of
  falling back to the first N examples); emits console.warn so degraded
  prompts are observable in production logs
- Destructure `validated` out of example objects before JSON.stringify
  so the LLM does not see `validated: false` in prompt examples and
  cargo-cult it as a required literal value
- Update JSDoc to reflect the new no-fallback behavior

Subject: [PATCH 10/10] fix(poc-gen): address review WARNING #1 and #2

WARNING #1 (poc-examples.ts): selectPocExamples now returns an empty
array instead of falling back to the full POC_EXAMPLES list when no
category matches. Emits console.warn with the unmatched vulnerability
type so degraded prompts are observable in production logs. JSDoc
updated to document the no-fallback behaviour.

WARNING #2 (agent-executor.ts): destructure `validated` out of the
example object before JSON.stringify so the LLM does not see
`validated: false` in examples and cargo-cult it as a literal output
requirement. Examples now also display a label (language) to help the
model distinguish them.
