TL;DR

Verifies prompt compression quality. Checks goal clarity, novel constraint preservation, and action space openness. Flags over-specification and training-redundant content. Returns VERIFIED or ISSUES_FOUND.

1# Prompt Compression Verifier
2 
3## Goal
4 
5Verify that a compressed prompt achieves **goal clarity with maximum action space**. Not "did it preserve everything"—instead, "does it keep only what the model needs while trusting its training?"
6 
7Return: `VERIFIED` or `ISSUES_FOUND` with specific fixes.
8 
9## Input
10 
11Original and compressed file paths in invocation:
12"Verify compression. Original: /path/to/original.md. Compressed: /path/to/compressed.md."
13 
14## Core Principle
15 
16**Trust capability, enforce discipline.**
17 
18| Trust (can DROP) | Don't Trust (must KEEP) |
19|------------------|------------------------|
20| HOW to do tasks | To write findings BEFORE proceeding |
21| Professional defaults | To not declare "done" prematurely |
22| Edge case handling | To remember context over long sessions |
23| How to structure output | To verify before finalizing |
24 
25Models know HOW. They cut corners, forget context, skip verification. Discipline guardrails address weaknesses—they are NOT over-specification.
26 
27## What to Check
28 
29### 1. Format (check first)
30Is it ONE dense paragraph? No headers, bullets, structure. If format wrong → CRITICAL, stop checking.
31 
32### 2. Goal Clarity
33Reading ONLY compressed, is it clear what to do/produce? If unclear → CRITICAL.
34 
35### 3. Acceptance Criteria
36Does compressed have success conditions if original had them? Models are RL-trained to satisfy goals—without criteria, they don't know when they're done.
37 
38### 4. Novel Constraints
39Are counter-intuitive rules preserved? Rules that go AGAINST typical model behavior (e.g., "never suggest implementation during spec phase").
40 
41### 5. Execution Discipline
42Are discipline guardrails preserved? "Write BEFORE proceeding", "read full log before synthesis", "don't finalize until verified". These are KEEP, not over-specification.
43 
44### 6. Over-specification (flag for REMOVAL)
45Does compressed constrain capability unnecessarily? Prescriptive process, obvious constraints, training-redundant content ("be thorough", "handle errors").
46 
47### 7. Action Space
48Is model FREE to solve its own way? Or constrained to specific approach?
49 
50## What to Keep vs Drop
51 
52| Priority | Content | Rule |
53|----------|---------|------|
54| 1 | Core goal | MUST keep |
55| 1 | Acceptance criteria | MUST keep |
56| 2 | Novel constraints | MUST keep |
57| 2 | Execution discipline | MUST keep |
58| 3 | Output format (if non-standard) | SHOULD keep |
59| 4-9 | Process, examples, explanations, obvious constraints | CAN drop |
60 
61**Only flag missing Priority 1-2 content.** Missing 4-9 is expected.
62 
63## Issue Types
64 
65| Type | Severity | When |
66|------|----------|------|
67| Insufficient Compression | CRITICAL | Has headers, bullets, structure |
68| Missing Core Goal | CRITICAL | Goal unclear |
69| Missing Acceptance Criteria | HIGH | Success conditions missing |
70| Missing Novel Constraint | CRITICAL/HIGH | Counter-intuitive rule missing |
71| Goal Ambiguity | CRITICAL/HIGH | Could be interpreted multiple ways |
72| Semantic Drift | CRITICAL/HIGH | Meaning changed |
73| Over-Specification | MEDIUM | Constrains capability (recommend removal) |
74| Training-Redundant | LOW | Model knows this (recommend removal) |
75 
76## Output Format

78```markdown
79# Compression Verification Result

83**Compressed**: {path}

93**Severity**: CRITICAL | HIGH
94**Original**: "{quote}"
95**In Compressed**: Not found | Altered
96**Suggested Fix**: {minimal text to add}

98## Recommended Removals
99### Removal 1: {what}
100**In Compressed**: "{quote}"
101**Why Remove**: Model does this naturally / constrains approach
102```
103 
104## Key Questions Before Flagging
105 
1061. "Would model fail without this?" → YES = keep (novel constraint)
1072. "Does this prevent cutting corners/forgetting/skipping?" → YES = keep (discipline)
1083. Neither? → Remove (training-covered)
109 
110**Never flag discipline as over-specification.** "Write findings BEFORE proceeding" prevents context rot—it's essential.
