+# Autoresearch — the self-improving "learn a skill" loop
+
+When the agent needs to do something it doesn't know how to do, it researches the
+topic on the public web, synthesizes a reusable `SKILL.md` *grounded only in the
+pages it read*, saves it (quarantined), and applies it — learning the capability
+itself instead of guessing. Inspired by [karpathy/autoresearch](https://github.com/karpathy/autoresearch)
+(an autonomous loop that produces lightweight steering artifacts; here the artifact
+is a skill).
+
+This matters most for the **local model** (qwen3.5:9b via Ollama): a 9B confidently
+answers niche DevOps questions from memory — often subtly wrong, which is dangerous
+when commands run on real servers.
+
+## How it triggers (the important part)
+
+A weak local model will **not** reliably pick a rarely-used `learn_skill` tool out of
+~15 on its own. Measured trigger recall across every prompt wording we tried was ~0 —
+even for a *fictional* tool it had never heard of, it answered in prose rather than
+admitting the gap.
+
+So the reliable trigger is **not** the model self-selecting the tool. It is a
+**pre-turn classifier** (`autoresearch::assess_gap`): one cheap, temperature-0
+question — *"does this need specific commands/config for a named tool you're unsure
+of? name the topic, or say NONE."* A 9B answers a focused, direct question far more
+reliably than it spontaneously reaches for a rare tool. Measured: **recall ~0.75,
+precision 1.00** (zero false positives on `ls` / math / file edits).
+
+### The autopilot (agent.rs)
+
+On every local, tool-capable, non-casual turn (gated by `agent.learn_autopilot`,
+default on):
+
+1. **Classify** — `assess_gap` runs once. If it returns `NONE`, nothing happens (no
+   latency beyond one tiny call).
+2. **Research** — on a detected gap with no covering skill, `autoresearch::learn`
+   runs the full loop (below). The expensive web research only runs on a genuine gap.
+3. **Inject** — the resulting skill is appended to the system prompt as
+   *"Just-researched skill for this task — APPLY IT"*, and the user sees a
+   *"Learned a skill for X — applying it"* status.
+4. **Answer** — the model answers using the injected, verified-against-sources steps.
+
+The model can also call the `learn_skill` tool directly, and the reflection pass
+writes a `[gap]` memory bullet when the agent visibly declines — but the autopilot
+is what makes it dependable.
+
+## The research loop (`autoresearch::learn`)
+
+1. **Dedup** — if an installed skill already covers the topic, return it; skip research.
+2. **Sanitize the query** — private IPs, internal hostnames (`.internal`/`.local`/
+   `.lan`), the user's own VPS hostnames, credential markers, and high-entropy tokens
+   are stripped *before* the query reaches DuckDuckGo. The search topic is the generic
+   capability, never the specific incident.
+3. **Gather sources** — search, then **fetch the top 1–2 result pages** (load-bearing:
+   snippets alone are too thin to ground real commands). All fetches reuse the
+   SSRF-guarded `web_tools` path.
+4. **Synthesize** — one low-temperature (0.15) call fills a fixed `SKILL.md` skeleton
+   **using only the fetched source text**, with an explicit `# TODO: not found in
+   sources` escape hatch so it leaves gaps blank instead of confabulating.
+5. **Validate, de-fang, scan, save** (`process_synthesized`, a pure function):
+   - structural gate (real `description:` front-matter, ≥1 command, cited sources that
+     match pages actually fetched, no model prompt-leakage);
+   - **de-fang** destructive commands (`rm -rf`, `mkfs`, `dd`, `chmod 777 /`, …) by
+     rewriting the line to `# REQUIRES APPROVAL:` — kept, never silently deleted;
+   - **security scan** (`commit_candidate`): **NVIDIA SkillSpector** is the primary
+     static analyzer when installed (68 patterns / 17 categories: prompt injection,
+     exfiltration, privilege escalation, supply chain, dangerous-code AST, YARA, …),
+     run static-only (`--no-llm`, no API key); the built-in heuristic is the always-on
+     backstop. Both gate at a **stricter threshold** than user-chosen installs (≥40 /
+     `is_blocking`, vs 60 for `skill_install`) — a researched skill is more untrusted
+     than one the user picked, so pipe-to-shell (`curl … | sh`) is refused outright;
+   - **quarantine** under the `unverified/` category with server-authored provenance
+     front-matter (`status: draft`, `origin: autoresearch`, `verified: false`,
+     `sources: […]`) and an UNVERIFIED banner, **never overwriting** an existing skill.
+
+## Why this is safe
+
+A skill is a file the agent later *follows as trusted instructions*, so web text
+laundered into a `SKILL.md` is a prompt-injection / RCE vector. The laundering is
+closed at every step: the query never carries private context out; synthesis is
+grounded and cold; the output is validated, de-fanged, and scanned at a stricter bar
+than installs; it lands in a distinct `unverified/` namespace with a banner so the
+distrust label is re-attached every time it's re-injected; and the agent is told never
+to run a destructive command from a learned skill without the user's approval.
+
+## The security scanner (NVIDIA SkillSpector)
+
+Every skill — researched, downloaded (`skill_install`), or otherwise — is scanned
+before it's saved or installed, because a `SKILL.md` is followed as trusted
+instructions. The scanner is **NVIDIA SkillSpector** ([github.com/NVIDIA/skillspector](https://github.com/NVIDIA/skillspector))
+when installed, falling back to a built-in pure-Rust heuristic otherwise.
+
+- **Install** (one click in Settings → Security, or):
+  `uv tool install git+https://github.com/NVIDIA/skillspector.git` (uv provisions
+  the required Python 3.12 automatically). The app finds the executable via
+  `uv tool dir --bin` even when it isn't on `PATH`.
+- Runs **static-only** by default (`scan … -f json --no-llm`) — no API key, no network
+  beyond the optional OSV.dev dependency check.
+- **Deep analysis (opt-in)**: Settings → Skills → "Deep analysis with the local model"
+  adds SkillSpector's LLM semantic checks against your local Ollama (OpenAI-compatible
+  endpoint; nothing leaves the machine). Use a **non-thinking instruct model** (or a
+  cloud model) — *thinking* models (qwen3.x) emit long `<think>` traces that overrun
+  SkillSpector's completion budget, so a deep scan with them fails and **falls back to
+  the static SkillSpector scan** (never down to the weak built-in heuristic). Stored in
+  `skills.scanner_deep` / `skills.scanner_model`; the endpoint/model derive from the
+  active Ollama provider.
+- Verdict: `risk_assessment.{score,severity,recommendation}` + an `issues[]` list.
+  Blocking on score ≥ threshold, HIGH/CRITICAL severity, or a `DO_NOT_INSTALL`
+  recommendation. Verify with `xconsole-bench scanner` (a malicious sample scores
+  71/HIGH/DO_NOT_INSTALL → blocked; a clean one 0/LOW → allowed); `--deep` exercises the
+  LLM path.
+
+## Settings
+
+- `agent.learn_autopilot` — pre-turn gap detection + auto-research (default **on**).
+- `agent.self_improve` — the reflection pass that writes `[lesson]`/`[gap]` memory
+  bullets (default **on**).
+- **Skill scanner** — Settings → Security shows whether SkillSpector is active and
+  installs it in one click (`skill_scanner_status` / `install_skill_scanner` commands).
+
+## Tested
+
+`xconsole-bench` modes exercise every layer:
+
+- `selftest` — pure, no model/network: injection refused, destructive de-fanged,
+  quarantine + no-overwrite, query sanitization, structural validation, classifier
+  reply parsing (59 checks).
+- `learnclassify` — the gap classifier as a TP/FP/TN/FN confusion matrix.
+- `learntune` — A/B sweep of guidance/tool-description variants (how we learned that
+  prompt-only triggering doesn't work).
+- `learn` — the live full loop on a real topic **and** the autopilot end-to-end
+  (gate → research → inject → grounded answer).
+
+Deferred to a future "overnight" pass (v2): promoting `draft → verified` from
+execution outcomes, refining a skill that failed in use, proactive research of
+recurring `[gap]`s, and a skills dedup/merge pass.

 opt-in, so they cost nothing until you add one. The `live_hook_ms` figure is dominated
 by process-spawn latency (lower on Unix `sh -c`); a hook that does real work adds its own time.
 
+## 1a. Harder suites — `hard` and `recall`
+
+The core `agent` suite saturates at 100% on `qwen3.5:9b`, so it no longer
+discriminates. Two harder, **scored** suites add headroom (so the history can show
+learning/regressions):
+
+```bash
+# Discriminative agent suite — tool-boundary routing traps + adversarial
+# action-vs-explain restraint (a 9B does NOT ace these). Reports an overall pass-rate
+# (with a Wilson CI) and a per-tier breakdown (hard / expert).
+./src-tauri/target/release/xconsole-bench.exe hard --samples 3
+
+# Reasoning-unlocks-recall experiment — single-hop factual questions answered three
+# ways: direct, reason-first, and a dummy "Let me think" buffer.
+./src-tauri/target/release/xconsole-bench.exe recall --samples 3
+
+# Closed learning loop — answer unfamiliar-tool tasks COLD (memory), let the
+# autoresearch loop build a skill for each, then answer WARM (skill injected).
+# Records cold/warm as two history points so the dashboard shows the before/after.
+./src-tauri/target/release/xconsole-bench.exe learnloop --samples 3
+```
+
+`learnloop` is the experiment that asks "does the agent actually get better by
+learning?" — cold vs warm pass-rate, plus a persistence check (a second `learn()`
+must dedup to the existing skill, no re-research). It also honestly catches the
+failure mode: a low-quality researched skill can *regress* a task, which is why
+draft skills stay quarantined until execution-verified.
+
+`recall` tests Google Research's *"Thinking to Recall: how reasoning unlocks parametric
+knowledge in LLMs"* on our local model: does a reasoning trace surface facts the model
+has in its weights but can't recall when answering directly? It reports `direct`,
+`reason`, and `buffer` accuracy and the **reasoning gain** (`reason − direct`). Per the
+paper, a large positive gain means reasoning unlocks recall (factual priming); a gain
+from the dummy `buffer` condition isolates the pure compute-buffer effect; a *negative*
+gain flags the paper's failure mode (a hallucinated intermediate fact derailing the
+answer). The `hard`/`recall` scenarios were generated and adversarially fact-checked by
+a multi-agent workflow so their expected answers are correct.
+
+## 1b. Benchmark history — scores over time (HTML dashboard + OKF bundle)
+
+Every **scored** run (`agent`, `hard`, `recall`, `ablation`, `learn`, `llm`, `all`) is
+appended to `bench/results/history.jsonl` and rendered two ways automatically:
+
+- **`bench/results/history.html`** — a self-contained dashboard (open it in any
+  browser; no server, no external assets) charting pass-rate and latency over time,
+  with a **Wilson 95% confidence interval** on every pass-rate.
+- **`bench/history/`** — the same history as an **[Open Knowledge Format](https://github.com/GoogleCloudPlatform/knowledge-catalog/tree/main/okf)**
+  bundle (Google's portable markdown+YAML standard): one typed concept per run
+  (`runs/*.md`), a chronological `log.md`, and an `index.md`. Portable, vendor-neutral,
+  readable in any editor and on GitHub.
+
+```bash
+# Rebuild the dashboard + OKF bundle from the existing history (no model needed):
+./src-tauri/target/release/xconsole-bench.exe report
+
+# Skip recording a run (e.g. a throwaway/tuning run):
+./src-tauri/target/release/xconsole-bench.exe agent --no-history
+```
+
+**Methodology** (applied + cited in the dashboard footer):
+
+- **Confidence intervals, not point estimates.** A pass-rate from a few samples is
+  noisy — 3–5 samples is *often insufficient* and the same source can wander ±1 pass.
+  Each pass-rate is reported with a Wilson 95% CI; when two runs' intervals overlap,
+  the difference isn't real. (Google Research, *"Building better AI benchmarks: how
+  many raters are enough?"* — more items beats more samples for an accuracy metric.)
+- **`time for 100 output tokens` = TTFT + 100 / (tok/s)** — one comparable latency
+  number across runs. (Artificial Analysis methodology.)
+- **Revealed behavior vs. self-report.** The learn-loop eval measures what the model
+  *does* (does it route to `learn_skill`?) against what it *claims* (the classifier's
+  self-assessment) — the gap is the model's overconfidence. (Google Research,
+  *"Evaluating alignment of behavioral dispositions in LLMs."*)

+//! Autoresearch: the capability-gap → web research → self-authored SKILL.md loop.
+//!
+//! When the agent needs to do something it doesn't know how to do, it calls one
+//! tool (`learn_skill`) and this module does the rest: research the topic on the
+//! public web, synthesize a concise SKILL.md *grounded only in the fetched pages*,
+//! and save it — so the agent learns the capability itself instead of guessing.
+//! Inspired by karpathy/autoresearch (an autonomous loop that produces reusable
+//! steering artifacts; here the artifact is a skill, not a training tweak).
+//!
+//! SECURITY (the load-bearing part — see the design critique that shaped this):
+//! a skill is a file the agent later *follows as trusted instructions*, so web text
+//! laundered into a SKILL.md is a prompt-injection / RCE vector. Defenses, all here:
+//!   1. The outbound search query is SANITIZED (private IPs, internal hostnames,
+//!      credential markers redacted) before it ever reaches DuckDuckGo.
+//!   2. Synthesis is grounded ONLY in fetched source text, low-temperature, fills a
+//!      fixed skeleton, and may write `# TODO: not found in sources` instead of
+//!      inventing commands.
+//!   3. The result is STRUCTURALLY VALIDATED (real front-matter, a real command, a
+//!      real source URL, no prompt-leakage) and DE-FANGED (destructive commands are
+//!      rewritten to `# REQUIRES APPROVAL:` lines, never silently dropped).
+//!   4. It is SCANNED with the same `skill_scan` gate that guards `skill_install`;
+//!      a blocking score refuses the save outright.
+//!   5. It is written to a QUARANTINE namespace (`unverified/`) with provenance
+//!      front-matter and an UNVERIFIED banner, never overwriting an existing skill,
+//!      so the distrust label is re-attached every time it is re-injected.
+//!
+//! The post-synthesis pipeline (`process_synthesized`) is a pure function over the
+//! raw model output, so the security behavior is unit-testable with no model and no
+//! network (see `bench learn`).

+// the model has in its weights but can't recall when answering directly — via a

+// and "factual priming" (the trace surfaces related facts that cue the answer).
+//
+// Three conditions per single-hop factual question (the paper's experiments 1 & 2):
+//   A direct   — answer immediately (our app's default: think:false, terse).
+//   B reason   — recall related facts step by step, THEN answer ("factual priming").
+//   C buffer   — pad with a meaningless "Let me think." string, THEN answer (isolates
+//                the pure compute-buffer effect from semantic reasoning).
+// If B >> A, reasoning unlocks recall here; if C > A too, part of it is just compute.
