😤 The Developer's Daily Pain

Every time you ask your AI agent to fix a bug, this happens:

💸

Token Waste

Your entire codebase gets dumped into context. 78% of tokens are irrelevant noise — CSS, README, changelogs — burning API credits.

78% wasted
🔄

Partial Failures

The AI sees auth/db.py but misses config/database.py. It generates code with the wrong DB connection. You re-prompt 3-5 times.

3-5x re-prompts
🧠

Memory Bloat

Duplicate files waste tokens. auth/db.py and auth/db_backup.py are nearly identical — 85 tokens burned on redundant content.

0 dedup
📉

No Cross-Session Learning

You fixed this same SQL injection pattern last week. The LLM forgot. Every session starts from absolute zero.

13 files ingested → 4 relevant selected → in 0.47ms

✅ Selected (high value)

auth/db.py 85 tok entropy: 0.89 ★ SQL injection
auth/queries.py 72 tok entropy: 0.87 ★ parameterized

Total: 247 / 250 tokens (98.8% budget utilization)

❌ Excluded (noise / duplicate)

README.md 120 tok → low relevance
static/styles.css 140 tok → low relevance
utils/email.py 110 tok → low relevance
CHANGELOG.md 95 tok → low relevance

🔧 10 Real Subsystems Under the Hood

🧮
Shannon Entropy Scoring
Measures information density — ranks code by actual value, not file size
🔍
64-bit SimHash Dedup
Near-duplicate detection via hamming distance < 3 — saves wasted tokens
🎯
Hybrid Semantic Matching
SimHash + n-gram Jaccard blend for query-aware relevance ranking
🎒
0/1 Knapsack DP
Maximizes total value within token budget — optimal in sub-millisecond time
🧠
Ebbinghaus Decay
Older fragments naturally deprioritized via exponential forgetting curve
🔗
Import Dependency Graph
Auto-links related files via import/identifier analysis for context coherence
⚖️
Compare-Calibrate Filter
Post-selection redundancy check — swaps similar fragments for diversity
🎲
ε-Greedy Exploration
Occasionally explores new fragments to prevent feedback loop starvation
🛡️
SAST Security Scanner
Auto-flags hardcoded secrets, SQL injection, unsafe patterns in real-time
💀
Skeleton Substitution
Fits structural summaries of excluded files into remaining budget space
