Raw multi-engine aggregation had no dedupe, no filtering and no reranking.
Measured 2026-09-26: 'best practices agent context management' returned
bestbuy.com and merriam-webster.com, plus 4 content farms, with medium.com twice;
'proxmox thin pool metadata exhaustion recovery' put four SEO blogs ABOVE the
real Proxmox forum threads. Identical queries also ranked DIFFERENTLY between
runs, which is why the fix is deterministic rather than trusting the engines.
scripts/search-agent-consume.py:
1. dedupe by normalised URL (tracking params and fragments stripped)
2. drop non-answers - shopping/dictionary hosts, navigational host roots,
search/shopping/cart/login paths and query keys
3. demote content farms and promote primary sources
4. STABLE sort (score desc, then original position) so runs are reproducible
5. extract page text for the top N via Firecrawl POST /v1/scrape under an
explicit character budget, so an agent gets usable material in ONE call
6. emit stable JSON with engine provenance and source_type
Policy is config, not code: config/search-ranking.yaml holds demote_domains,
prefer_domains, non_answer rules and the extraction budget, so it is reviewable
and changeable without touching the module. Content farms are DEMOTED rather
than dropped so a useful hit is not lost, it just cannot outrank a primary.
A '/products/' path rule was REMOVED after the before/after run caught it
dropping docs.digitalocean.com/products/inference/... - a legitimate docs page.
Shopping is caught by the host list instead, which has no such false positive.
Measured: 'best practices...' top 8 becomes anthropic, langchain, jetbrains,
blog.jetbrains, docs.langchain, reddit, cursor, reddit - no content farm.
'proxmox thin pool...' moves the forum threads from positions 5-9 to 1-4.
Extraction: 5 items, 12000 chars of 12000 budget, 0 failures, 5.28s; whole run
6.4s wall.
Contract: search-agent-consumption.prose.md, including the honest reachability
gap - the pi MCP search server's shape is not ours to change, so this layer is
NOT wired into it.

| function | search-agent-consumption | Agent-consumption layer in front of SearXNG + Firecrawl. Raw multi-engine aggregation returns results with no dedupe, no filtering and no reranking; measured 2026-09-26 that put bestbuy.com and merriam-webster.com into "best practices agent context management", and put four SEO blogs above the real Proxmox forum threads on a precise technical query. Identical queries also ranked DIFFERENTLY between runs, which is why the layer is deterministic rather than dependent on engine behaviour. Pipeline: dedupe -> drop non-answers -> demote content farms / promote primary sources -> stable sort -> extract page text for the top N under an explicit character budget -> stable JSON. Policy lives in config, not code. Call it when an agent needs search RESULTS rather than links: it returns usable page text in one call instead of a snippet plus a second fetch. | 1.0.0 |
Where the policy lives
config/search-ranking.yaml — reviewable, no code change needed to adjust:
| key | effect |
|---|---|
non_answer.hosts / path_patterns / query_keys / host_root |
dropped outright |
demote_domains |
ranked below everything, never dropped |
prefer_domains |
promoted above default rank |
ranking.* |
demote_penalty, prefer_bonus, multi_engine_bonus |
extraction.* |
top_n, total_chars, per_item_chars, timeout_seconds |
Demotion, not deletion, for content farms: a genuinely useful hit is not lost, it simply cannot outrank a primary source. Non-answers are dropped because they cannot answer a question at all.
Usage
python3 scripts/search-agent-consume.py "query text" # JSON
python3 scripts/search-agent-consume.py --no-extract "query" # ranking only
python3 scripts/search-agent-consume.py --explain "query" # + drop reasons
Exit 0 ok, 1 nothing survived filtering, 2 the layer could not run.
Output shape
Stable JSON:
{
"query": "...",
"raw_result_count": 46,
"returned_count": 44,
"dropped_count": 2,
"engines": ["bing", "brave", "duckduckgo", "yandex"],
"results": [
{"rank": 1, "title": "...", "url": "...", "host": "...",
"source_type": "official|code|qa|forum|discussion|web|content-farm",
"engines": ["bing"], "score": 100.0,
"excerpt": "...", "extraction": "ok|truncated|skipped_budget_exhausted|empty|failed:<Type>"}
],
"extraction": {"extracted": 5, "chars_used": 12000, "budget": 12000,
"failures": 0, "seconds": 5.28}
}
--explain adds dropped: [{url, reason, position}] so the filter is auditable
rather than magic.
Measured before/after (2026-09-26)
Fixed query set. Relevance judged per query, not by impression.
best practices agent context management
| before (raw SearXNG) | after (layer) | |
|---|---|---|
| 1-2 | anthropic, stackai | anthropic, langchain |
| 3-4 | aitechmonk, agentic-design | jetbrains, blog.jetbrains |
| 5-6 | mindstudio, sparkco | docs.langchain, reddit |
| 7-8 | langchain, medium | cursor, reddit |
| verdict | 4 relevant of 10; 4 content farms; medium.com twice | top 8 all primary/discussion; no content farm in the top 8 |
proxmox thin pool metadata exhaustion recovery
| before | after | |
|---|---|---|
| 1-4 | vormox, linuxoperatingsystem, riparazioneserver, bigiron (all SEO/thin) | forum.proxmox.com, forum.proxmox.com, gist.github, github |
| 5-9 | forum.proxmox.com x2, voxfor, github, gist | forum.proxmox.com, serverfault, forum.proxmox.com, reddit |
The primary sources moved from positions 5-9 to 1-4.
Rule proof (--explain, and a direct check of the classifier):
DigitalOcean docs -> KEEP (a '/products/' path rule was REMOVED after the
before/after run caught it dropping this page)
Best Buy -> DROP shopping_or_dictionary_host
Merriam-Webster -> DROP shopping_or_dictionary_host
bare homepage -> DROP navigational_host_root
proxmox.com home -> KEEP (preferred host root: a repo/docs front door is
legitimately the answer)
github repo -> KEEP
Extraction cost (criterion 4):
extracted 5 items, 12000 chars used of 12000 budget, 0 failures, 5.28s
whole run end-to-end: 6.4s wall
Regression guard
search-stack-visibility asserts the layer still ranks correctly: for the fixed
query set, no demote_domains host may appear in the top 3, and the two known
non-answers must not be returned. Without it this layer could silently rot back
to raw ordering, which is exactly what happened to the endpoint colours.
Reachability, and one honest gap
- Hermes agents reach it directly: it reads the same
SEARXNG_URLandFIRECRAWL_URLthey already use. - pi agents (MCP search server): the MCP server's request/response shape is not ours to change, so this layer is NOT wired into it. That is a real gap, stated rather than claimed as coverage. Closing it would require a change on the MCP side, which is outside this repo.
Constraints
Does not touch the live SearXNG or Firecrawl service paths. Third-party
google cse is not a hard requirement of this layer — if it 429s, ranking still
works from the remaining engines. No credential is added or required.
