+# Skills Agent-Driven E2E Benchmark
+
+This benchmark validates the meta skill workflow for capability-gap discovery, ClawHub installation, and security-gated rollout.
+
+## Scope
+
+- Domain: skill discovery + installation + update
+- Focus: `skills/meta-skill-installer`
+- Providers: default `kimi-coding` (override with `PROVIDERS`)
+- Cases: 5
+
+Case prompts are stored in:
+- `scripts/e2e-skills-benchmark/cases/`
+
+## Real ClawHub Examples Used
+
+The case set references real public pages from ClawHub:
+
+- [CalDAV Calendar](https://clawhub.ai/skills/caldav-calendar)
+- [Home Assistant](https://clawhub.ai/skills/homeassistant)
+- [CodexMonitor](https://clawhub.ai/odrobnik/codexmonitor)
+- [Spotify (gap-discovery UX flow)](https://clawhub.ai/search?q=spotify)
+- [Notion (gap-discovery UX flow)](https://clawhub.ai/search?q=notion)
+
+## Prerequisites
+
+1. Credentials configured (`pnpm multica credentials init` if needed)
+2. Dependencies installed in repo (`pnpm install`)
+3. `clawhub` CLI available, or allow runtime fallback to `npx -y clawhub`
+4. Required env:
+
+```bash
+export SMC_DATA_DIR=~/.super-multica-e2e
+export MULTICA_API_URL=https://api-dev.copilothub.ai
+```
+
+## Run Benchmark
+
+```bash
+scripts/e2e-skills-benchmark/run.sh
+```
+
+Defaults:
+
+- Providers: `kimi-coding`
+- Case glob: `case-*.txt`
+- Max parallel workers: `1`
+- Per-case timeout: `1200s` (`CASE_TIMEOUT_SEC=0` to disable)
+- Output directory: `.context/skills-e2e-runs/<timestamp>/`
+
+Generated artifacts:
+
+- `manifest.tsv`: provider/case/status/session/log metadata
+- `analysis.txt`: human-readable pass/fail report
+- `analysis.json`: structured detailed check output
+
+## Run Subset
+
+Only one case:
+
+```bash
+CASE_GLOB="case-01-*.txt" scripts/e2e-skills-benchmark/run.sh
+```
+
+Multiple providers:
+
+```bash
+PROVIDERS="kimi-coding claude-code" scripts/e2e-skills-benchmark/run.sh
+```
+
+Faster throughput:
+
+```bash
+MAX_PARALLEL=2 CASE_TIMEOUT_SEC=1800 scripts/e2e-skills-benchmark/run.sh
+```
+
+## Analyzer Checks
+
+For each run:
+
+1. `run_start` and `run_end` both present
+2. `run_end.error` is empty/null
+3. `tool_start` and `tool_end` are paired
+4. no `tool_end.is_error=true`
+5. at least one `exec` tool call exists
+6. case-specific command evidence in `tool_start.args`:
+   - `clawhub search`
+   - `clawhub install`
+   - `review-skill-security.mjs`
+   - for case 03 also `clawhub update`
+   - for case 04, prompt is a natural user request only; agent must self-discover capability gap, propose ClawHub + security review + install confirmation, and must not run workaround commands (`osascript`, `ha.sh`, `spogo`, `spotify_player`) before user confirmation
+   - for case 05, prompt is a natural Notion request; agent must discover missing capability, search skill candidates, trigger `install_guard` (blocked until confirmation), and ask for explicit install consent plus token/auth prerequisites
+
+## Notes
+
+- These are agent-driven tests; prompt intent plus run-log evidence are both evaluated.
+- `SMC_DATA_DIR=~/.super-multica-e2e` avoids polluting normal user skill/session data.
+- If a case fails, open `manifest.tsv` and inspect the matching `session_dir/run-log.jsonl`.

+description: Detect missing capabilities, search clawhub.ai for matching skills, run security review on candidate skills, and install safe skills into Multica. Use when a task cannot be completed with current skills/tools or when the user asks to discover/install/update skills from ClawHub.

+---
+
+# Meta Skill Installer
+
+Use this skill to close capability gaps by discovering and installing skills from ClawHub with a mandatory security gate.
+
+## Safety Defaults
+
+- Always run in this order: identify gap -> search -> stage install -> security review -> install to managed dir -> validate.
+- Never install directly into the active skills directory before review.
+- If risk is `dangerous`, stop and explain why.
+- If risk is `needs-review`, ask for explicit user confirmation before final install.
+
+## Resolve Paths and Commands
+
+Use Multica managed skills path, not the current workspace:
+
+```bash
+DATA_DIR="${SMC_DATA_DIR:-$HOME/.super-multica}"
+SKILLS_DIR="$DATA_DIR/skills"
+META_SKILL_DIR="$SKILLS_DIR/meta-skill-installer"
+
+if command -v clawhub >/dev/null 2>&1; then
+  CLAWHUB_CMD=(clawhub)
+else
+  CLAWHUB_CMD=(npx -y clawhub)
+fi
+```
+
+If neither command path works, install the CLI first (`npm i -g clawhub`) and retry.
+
+## Workflow
+
+### 1) Detect the Capability Gap
+
+When the current task cannot be completed with existing skills/tools:
+
+- Summarize the missing capability in one sentence.
+- Convert it to a focused search query (tool + domain + action).
+- Keep the original user intent and success criteria.
+
+### 2) Search ClawHub
+
+Run one or more searches and collect top candidates:
+
+```bash
+"${CLAWHUB_CMD[@]}" search "<query>" --limit 10
+```
+
+Candidate ranking rules:
+
+- Primary: semantic relevance to the missing capability.
+- Secondary: clearer SKILL description and narrower scope.
+- Tertiary: lower operational risk (fewer privileged or remote-exec patterns).
+
+### 3) Stage Install in Quarantine Directory
+
+Install candidate skill into a temporary workdir first:
+
+```bash
+STAGING_DIR="$(mktemp -d "${TMPDIR:-/tmp}/multica-skill-review.XXXXXX")"
+"${CLAWHUB_CMD[@]}" install "<slug>" --workdir "$STAGING_DIR" --dir skills --version "<optional-version>" --force
+```
+
+Expected staged path:
+
+```bash
+"$STAGING_DIR/skills/<slug>"
+```
+
+### 4) Run Security Review
+
+Use this skill's scanner script against the staged skill:
+
+```bash
+node "$META_SKILL_DIR/scripts/review-skill-security.mjs" "$STAGING_DIR/skills/<slug>"
+```
+
+Interpret scanner output:
+
+- `riskLevel: safe` -> continue to install.
+- `riskLevel: needs-review` -> present findings, ask user for explicit confirmation.
+- `riskLevel: dangerous` -> block install by default.
+
+### 5) Install to Multica Managed Skills Directory
+
+Only after passing the review gate, install to the directory Multica actually loads:
+
+```bash
+mkdir -p "$SKILLS_DIR"
+"${CLAWHUB_CMD[@]}" install "<slug>" --workdir "$DATA_DIR" --dir skills --version "<optional-version>" --force
+```
+
+If skill already exists, use update:
+
+```bash
+"${CLAWHUB_CMD[@]}" update "<slug>" --workdir "$DATA_DIR" --dir skills --version "<optional-version>" --force
+```
+
+### 6) Post-Install Validation
+
+Validate presence and scan once more in the final location:
+
+```bash
+test -f "$SKILLS_DIR/<slug>/SKILL.md"
+node "$META_SKILL_DIR/scripts/review-skill-security.mjs" "$SKILLS_DIR/<slug>"
+```
+
+Then retry the original user task with the new skill.
+
+## Guardrails
+
+- Never claim installation success without path-level verification.
+- Never hide security findings; summarize concrete files and reasons.
+- Prefer pinned versions when available, and report the installed version to the user.
+- If the chosen skill requires secrets/API keys, pause after install and ask user to configure required env vars before using it.
