1	You are orchestrating the Exploitability Validation pipeline - a multi-stage system that validates vulnerability findings before exploit development.
2
3	## Shared Context - LOAD FIRST
4
5	IMPORTANT: Before executing ANY stage, load and internalize:
6	`.claude/skills/exploitability-validation/SKILL.md`
7
8	This contains:
9	- [CONFIG] Configuration settings
10	- [EXEC] Execution rules
11	- [GATES] MUST-GATEs 1-6 that apply to ALL stages
12	- [REMIND] Critical reminders
13
14	All gates must be followed throughout the pipeline. Reference SKILL.md if uncertain about any gate.
15
16	---
17
18	## Purpose
19
20	Prevent wasted effort by validating that findings:
21	1. Actually exist (not hallucinated)
22	2. Are reachable (not dead code)
23	3. Have working exploitation paths (not theoretical)
24
25	## Invocation
26
27	You receive: `<target_path> [--vuln-type <type>] [--findings <findings.json>]`
28
29	- `target_path`: Directory or file to analyze
30	- `--vuln-type`: Optional focus (e.g., `command_injection`, `sql_injection`, `xss`)
31	- `--findings`: Optional pre-existing findings to validate (skips Stage 0/A)
32
33	---
34
35	## Workflow
36
37	### Phase 0: Initialize
38
39	Create working directory: `.out/exploitability-validation-<timestamp>/`
40
41	```bash
42	mkdir -p .out/exploitability-validation-$(date +%Y%m%d_%H%M%S)
43	```
44
45	Store path as `$WORKDIR` for all subsequent operations.
46
47	---
48
49	### Phase 1: Stage 0 - Inventory
50
51	Load: `.claude/skills/exploitability-validation/stage-0-inventory.md`
52
53	Execute inventory building:
54	1. Enumerate all files in target_path
55	2. Exclude test/mock files
56	3. Extract functions per file
57	4. Write `$WORKDIR/checklist.json`
58
59	Verify output exists before proceeding.
60
61	---
62
63	### Phase 2: Stage A - One-Shot
64
65	Load: `.claude/skills/exploitability-validation/stage-a-oneshot.md`
66
67	Execute one-shot verification:
68	1. Assess each function for vuln_type
69	2. Attempt PoC for candidates
70	3. Write `$WORKDIR/findings.json`
71
72	Route based on findings:
73	- All PoCs succeed -> Skip to Phase 4 (Stage C)
74	- Some "not_disproven" -> Continue to Phase 3 (Stage B)
75	- All disproven -> Report "no exploitable findings" and exit
76
77	---
78
79	### Phase 3: Stage B - Systematic Process
80
81	Load: `.claude/skills/exploitability-validation/stage-b-process.md`
82
83	Execute systematic analysis for "not_disproven" findings:
84	1. Build attack trees
85	2. Form and test hypotheses
86	3. Track PROXIMITY
87	4. Attempt multiple attack paths
88	5. Update working documents
89
90	Output:
91	- `$WORKDIR/findings.json` (updated)
92	- `$WORKDIR/attack-tree.json`
93	- `$WORKDIR/hypotheses.json`
94	- `$WORKDIR/disproven.json`
95	- `$WORKDIR/attack-paths.json`
96	- `$WORKDIR/attack-surface.json`
97
98	---
99
100	### Phase 4: Stage C - Sanity Check
101
102	Load: `.claude/skills/exploitability-validation/stage-c-sanity.md`
103
104	Validate all findings against actual code:
105	1. Verify files exist
106	2. Verify code matches verbatim
107	3. Verify flow is real
108	4. Verify code is reachable
109
110	Update `$WORKDIR/findings.json` with sanity_check results.
111
112	Remove findings that fail sanity check from active consideration.
113
114	---
115
116	### Phase 5: Stage D - Ruling
117
118	Load: `.claude/skills/exploitability-validation/stage-d-ruling.md`
119
120	Filter findings:
121	1. Check for test/mock/example code
122	2. Check for unrealistic preconditions
123	3. Check for hedging language
124
125	Write `$WORKDIR/findings.json` with CONFIRMED findings.
126
127	---
128
129	### Phase 6: Stage E - Feasibility (Memory Corruption Only)
130
131	Load: `.claude/skills/exploitability-validation/stage-e-feasibility.md`
132
133	Applies to: buffer_overflow, heap_overflow, format_string, use_after_free, double_free, integer_overflow, out_of_bounds_read/write
134
135	Skip for: command_injection, sql_injection, xss, path_traversal, ssrf, deserialization
136
137	For applicable findings:
138	1. Locate compiled binary (check build output, common paths, or ask user)
139	2. Run `analyze_binary()` from exploit_feasibility package
140	3. Save context with `save_exploit_context()` (survives compaction)
141	4. Update finding with feasibility verdict and constraints
142
143	```python
144	import sys, os; sys.path.insert(0, os.environ["RAPTOR_DIR"])
145	from packages.exploit_feasibility import (
146	analyze_binary,
147	format_analysis_summary,
148	save_exploit_context
149	)
150
151	for finding in confirmed_findings:
152	if finding.vuln_type in MEMORY_CORRUPTION_TYPES:
153	result = analyze_binary(binary_path, vuln_type=finding.vuln_type)
154	context_file = save_exploit_context(binary_path)
155
156	finding.feasibility = {
157	'verdict': result.verdict, # Likely, Difficult, Unlikely
158	'chain_breaks': result.chain_breaks,
159	'what_would_help': result.what_would_help,
160	'context_file': context_file
161	}
162
163	# Update final status
164	if result.verdict == 'likely_exploitable':
165	finding.final_status = 'exploitable'
166	elif result.verdict == 'difficult':
167	finding.final_status = 'confirmed_constrained'
168	else:
