# Hacker News — evidence index

Compact evidence trail for the Hacker News connector (`hackernews-1`, LLM-agent topics). Synthesis lives on `/themes.md`, `/commitments.md`, etc.; this page only records ingestion coverage and notable items.

## Connector

- **Instance:** `hackernews-1` (Hacker News — LLM agent topics)
- **Backend:** public HN feeds (`top`, `new`, `best`) + Algolia HN search queries
- **Auth:** none — public feeds
- **Window:** last 24 hours
- **Latest fetch:** `2026-07-26T17:27:12Z`
- **Raw dump:** `~/.openwiki/connectors/hackernews/raw/2026-07-26T17-26-41-217Z/hackernews-results.json`

## Ingestion coverage

| Source | Items pulled |
| --- | --- |
| Feed: `top` | 30 ids / 25 resolved items |
| Feed: `new` | 30 ids / 30 resolved items |
| Feed: `best` | 30 ids / 17 resolved items |
| Unique stories across feeds | 63 |
| Search queries | 8 queries — see hit table below |

### Search query hits (this run)

Queries were pulled from `~/.openwiki/connectors/hackernews/config.json`. The first
column is the Algolia `nbHits` (total matching stories in HN's index), the rest is
a relevance judgment based on the first 20 returned items.

| Query | nbHits | Relevant? | Notes |
| --- | --- | --- | --- |
| `LLM agents` | 3 | low | danluu "Agentic test processes, LLM benchmarks…" (16 pts) + Oz-series knowledge graph Show HN + an Ask HN. |
| `claude code` | 18 | yes — strong | Multiple Show HN wrappers (Termic, terminai, Argus, Ruflo), Claude-Code-context-deletion post (13 pts), Opus-5-hardcoded-no-subagents (23 pts), 80%-prompt-cut (5 pts). Plus the 427-pt context-engineering-for-Claude-5 anchor. |
| `codex cli` | 19 | yes — partial | Same wrapper ecosystem as `claude code` (Hallmark, Termic, Ruflo, terminai). Hallmark is the only Show HN at 4 pts; rest is integration/blog noise. |
| `MiniMax` | 6 | no (string noise) | NixOS flake, organic-cell simulation, Brolly weather, scanwheel. No MiniMax-M3 signal this run. |
| `M3 model` | 0 | n/a | No hits. |
| `openwiki` | 0 | n/a | No hits this run — see OpenWiki brand signal below. |
| `deepagents` | 0 | n/a | No hits this run. |
| `langchain` | 0 | n/a | No hits this run. |

Query-set note: the last run focused on life-science / organoid / bioprinting /
local-LLM keywords (`organoid`, `bioprinting`, `3D bioprinter`, `local LLM`,
`ollama`, `CelVivo`, `3Brain`, `Cellink`, `ClinoStar`, `ClinoReactor`). This run
swaps to the LLM-agent topic set per Robin's source-specific instruction, so
organoid / vendor coverage is **not refreshed** in this fetch. Vendor brand
signal table from the prior run still applies — no new evidence either way.

## Notable items by theme

Items below are filtered from the 63 unique feed items plus the relevant
search-query hits. Each line: HN id, score, feed(s), one-line gist, URL. HN ids
are stable, so items stay referenceable across runs.

### context-engineering-claude5 (source-backed)

New this run — the dominant HN signal for Robin's AI-Agent-workflow focus.
Anchored by Anthropic's own blog post at 427 pts; reinforced by Claude Code
operational write-ups and an Opus 5 incident.

- **49051361** — score 427 — top — "The new rules of context engineering for Claude 5 generation models" (Anthropic blog). https://claude.com/blog/the-new-rules-of-context-engineering
- **49056194** — score 79 — top — "Elevated Errors for Opus 5" (Claude status incident).
- **49056022** — score 23 — new — "Claude Code has a hardcoded instruction telling Opus 5 not to use subagents" (r/ClaudeCode).
- **49056689** — score 13 — new — "Claude Code Deletes Your Context History from Your Device After 30 Days" (Claude docs).
- **49055752** — score 5 — new — "Claude Code Cut Their System Prompt by 80%. Does That Work for Small Models Too?" (antigma.ai).

Five items in 24h, all corroborating, ranging from official Anthropic comms to
community incident posts. This is the clearest AI-Agent-workflow signal in the
window and is routed to `/themes.md`.

### coding-agent-tooling (source-backed)

The Claude-Code / Codex-CLI wrapper / harness / safety-rail ecosystem. Heavy
Show-HN volume — every item is derivative tooling, but recurrence is real and
engagement is positive. Worth tracking as a watchlist-grade stream because
downstream tooling for the user's stack (Codex CLI, Claude Code) is where most
of the moving parts live.

- **49051072** — score 3 — new — "Ruflo: An agent meta-harness for Claude Code and Codex" (ruvnet). https://github.com/ruvnet/ruflo
- **49050011** — score 3 — new — "I was paying too much for Claude and codex here is how I reduced 90% of it" (AjnasNB/qarinah).
- **49055227** — score 3 — new — Show HN: terminai — "Integrate any CLI agent into any terminal". https://terminai.app
- **49056316** — score 2 — new — Show HN: Termic — desktop app for running CLI coding agents (Claude Code, Codex). https://termic.dev/
- **49054070** — score 2 — new — Show HN: "Rules that stop AI coding agents from breaking working code". https://github.com/avenna01-ceo/claude-code-survival-kr
- **49058547** — score 4 — new — "Hallmark – Anti-AI-Slop Design Skill for Claude Code, Cursor, and Codex" (Nutlope). https://github.com/Nutlope/hallmark
- **49058441** — score 2 — new — "Data loss in Claude Code and OpenAI Codex: when AI deletes user files" (firasd substack).
- **49058217** — score 3 — new — "Design.md for Design in Claude Code" (aifordevelopers substack).
- **49049978** — score 3 — new — "The Many Claudes of My Code" (shippingbinaries blog).
- **49053523** — score 3 — new — Show HN: Argus — VSCode Worktree Agent Session Manager.
- **49050042** — score 4 — new — Show HN: blind taste test for Claude and Codex designs.

Engagement is modest (≤ 4 pts each) but item count is dense — eleven items in
24h. Promote to full source-backed theme row only after at least one item
crosses 50 pts in a single run.

### llm-on-old-hardware (source-backed — promoted)

Recurrence confirmed in this run. Two independent high-engagement items on the
"tiny model on cheap hardware" theme. Promote from watchlist to source-backed.

- **49050512** — score 261 — top — "Running a 28.9M parameter LLM on an $8 microcontroller" (ESP32, slvDev). https://github.com/slvDev/esp32-ai
- **49053375** — score 186 — top — "Inflect-Micro-v2: complete voice in 9.36M parameters" (HuggingFace). https://huggingface.co/owensong/Inflect-Micro-v2
- **48922434** — score 274 — top, best — "Running Gemma 4 26B at 5 tokens/sec on a 13-year-old Xeon with no GPU" (prior run, anchor item).

Three high-engagement items across two runs; both pull from independent authors
and target different hardware tiers (legacy CPU, ESP32-class MCU, sub-30M-param
model card). The pattern is real, not coincidental.

### ai-safety-debate (source-backed — refreshed)

Two new items in this window — one essay/interview, one fiction piece — both
about LLM-extinction / alignment framing.

- **49059995** — score 3 — new — "Karen Hao: AI Doesn't Have to Be Built This Way" (Bloomberg).
- **49059660** — score 10 — new — "What if LLMs escape through inferences itself? This is fiction. For now" (agrillo.it).
- **49052912** — score 224 — top — "DeepSeek pause fundraise after comments on compute gap to US leaked (transcript)" (github demo). Adjacent: open-weight-lab geopolitics, not safety per se but routed here because it overlaps with the prior open-weight-ai theme.

### local-LLM-stream (watchlist — refreshed)

Adjacent to the user's "本地大模型部署" focus. Mostly derivative / tooling noise
this run, but the upstream signals (Debian policy, Cloudflare AI traffic
options) are substantive.

- **49050859** — score 199 — top — "LLM Usage in Debian: Three Proposals" (Debian vote 2026/vote_002). Real policy signal.
- **49052564** — score 173 — top — "Cloudflare's new AI traffic options for customers" (blog.cloudflare.com). Infra signal.
- **49052912** — score 224 — top — DeepSeek pause fundraise (also in ai-safety-debate; matters for "本地大模型部署" because DeepSeek is the canonical open-weight Chinese LLM).
- **49053375** — score 186 — Inflect-Micro-v2 (also in llm-on-old-hardware).

### agent-memory-architecture (watchlist — new)

Two Show HN items in 24h about agent-side memory / trust layers. Thin signal but
directly relevant to OpenWiki's own role (structured memory + doc trust for
agents).

- **49059959** — score 1 — new — Show HN: Worklog — "structured memory for Agent in one SQLite table" (xyb). https://github.com/xyb/worklog
- **49059889** — score 1 — new — "Open Knowledge format v0.2 tackles agentic trust" (Google Cloud blog).
- **49060215** — score 1 — new — Show HN: "Turn a diff into an evidence-backed Assumption Ledger" (Teycir/Assumptions). Adjacent — diff-as-evidence pattern is similar in spirit.

Low engagement; keep as watchlist. Promote when a high-engagement item lands.

## Themes not refreshed this run

The prior run surfaced these themes, none of which got fresh evidence in this
fetch (organoid / bioprinting / DeepSeek / open-weight queries were dropped
from the query set per the LLM-agent focus instruction):

- `open-weight-ai` — Inkling, Grok Build OSS, Siegel Endowment PDF from
  2026-07-16. Last seen unchanged (2026-07-16).
- `computer-use-agents` — Coasty YC launch, AI-agent databases, GPT-Red.
  Last seen unchanged (2026-07-16).
- `codex-openai` — Codex Micro, follow-up video, GPT-Red. Last seen
  unchanged (2026-07-16). The `coding-agent-tooling` row above is adjacent
  but distinct — that is downstream tooling, not OpenAI's own Codex work.
- `class-organoid-3d-bioprinting` — 12+ items from MIT / NPR / Nature /
  MSU / McGill. Last seen unchanged (2026-07-16). To re-verify, the next
  life-science-focused HN run should re-add the `organoid*`, `bioprinting`,
  and `3D bioprinter` queries.
- `MiniMax-m3` — HuggingFace card + Twitter launch. Last seen unchanged
  (2026-07-16). This run's `MiniMax` query returned 6 hits but they were
  all string noise (Brolly weather, NixOS flake, etc.); the `M3 model`
  query returned 0 hits.
- `openwiki-brand` — `langchain-ai/openwiki` 96 pts (2026-07-16). See
  OpenWiki brand signal below.

## OpenWiki brand signal

Search query `openwiki` returned **0 hits** in the 24h window. The prior run
(2026-07-16) confirmed the brand signal via `langchain-ai/openwiki` (96 pts,
Show HN). Absence in a single 24h window is expected — the project is not on
a daily release cadence. The theme row in `/themes.md` stays watchlist with
Last seen pinned to 2026-07-16 until the next positive hit.

Adjacent (not OpenWiki-the-brand) items worth flagging:

- **49059889** — "Open Knowledge format v0.2 tackles agentic trust" (Google Cloud blog) — different project, but the name overlap is enough that it shows up in any OpenWiki-adjacent search.

## Next update

Run `openwiki_ingest_connector connectorId=hackernews` (or `openwiki personal --update`) to refresh. Next run should re-add the life-science / organoid / vendor queries alongside the LLM-agent set if Robin wants both streams covered each day.
