Evidence
The assistant on this site answers from a search index of my work. Here is how well that search finds the right passage, measured by a script in this repository against the live index, with the questions and the misses published.
- 29 of 30fresh questions where the right passage was retrieved (97%), on a set I never tuned against
- 19 of 30of those had it in the top 3 (63%): ranking is weaker than retrieval
- 12 of 16unrelated questions refused by the cutoff alone, with no model call. The other 4 are left to a prompt rule
- 0%of retrieved chunks look like code (74% before I re-indexed from prose)
What was measured
- Measured on
- 2026-11-10
- Index
- 146 chunks: blog 53, case study 42, profile 27, projects 15, goals 6, extras 3
- Retrieval settings
- closest 8 chunks within a cosine distance of 0.7
- Refusal cutoff
- best match below 0.34 gets a fixed reply and no model call
- How a hit is judged
- each question lists text that must appear in the retrieved chunks, so it shows that the right evidence reached the model, not that the answer was good
The questions
Three sets, all written by me. The first was used to tune the chunking, so its numbers flatter the system. The second was written afterwards and never tuned against, so it is the number to trust.
Tuned against · 28 questions · 28 found in the top 8, 25 in the top 3
The set I tuned the chunking against: 100% found, 89% in the top 3. Treat as optimistic.

Fresh questions, never tuned against · 30 questions · 29 found in the top 8, 19 in the top 3
Written after the tuning, in different phrasing, including informal and misspelled questions. I fixed two content gaps it exposed (a career timeline and the places I have visited), so the one remaining miss is the honest one.

Unrelated questions · 16 questions · 12 refused by the cutoff
Weather, trivia, code help and requests to ignore instructions. Real questions never scored below 0.415 for their best match, and these scored at most 0.391, so the cutoff sits in a narrow gap. Questions it does not catch are handled by a rule in the prompt.

What this does not show
Both question sets are written by me, so neither is independent. The check does not judge whether an answer is good, only whether the right text was retrieved. Thirty questions is small. The index is rebuilt by a script, so it can drift from the site until that runs.
Inspect it
- The check, the fresh question set and the indexer.
- The story of how I found and fixed the problem: My portfolio assistant was retrieving code. I measured it, then fixed it.
- The system it measures: RAG Portfolio Assistant. Ask the assistant on this page anything and open "How this answer was made" under its reply to see what it retrieved.
