# NeuroSkill `session` and `sessions` Commands --- ## `session` — Single Session Breakdown Full metric breakdown for a single recording session, with first-half → second-half trend arrows. Index `0` = most recent, `1` = previous, and so on. ```bash npx neuroskill session # most recent session (default: 0) npx neuroskill session 0 # same npx neuroskill session 1 # previous session npx neuroskill session 2 # two sessions ago npx neuroskill session --json npx neuroskill session 1 --json | jq '.metrics.focus' npx neuroskill session 0 --json | jq '{focus: .metrics.focus, hr: .metrics.hr, trend: .trends.focus}' ``` **HTTP (two requests):** ```bash # Step 1 — get session list to find timestamps: curl -s -X POST http://127.0.0.1:8375/ \ -H "Content-Type: application/json" \ -d '{"command":"sessions"}' | jq '.sessions[0]' # Step 2 — fetch full metrics for that session: curl -s -X POST http://127.0.0.1:8375/ \ -H "Content-Type: application/json" \ -d '{"command":"session_metrics","start_utc":1740412800,"end_utc":1740415510}' ``` ### Example Output ``` ⚡ session [0] 20260224 2/24/2026, 8:00:00 AM → 8:45:10 AM 45m 10s 541 epochs Core Scores focus 0.70 ↑ (0.64 → 0.76) relaxation 0.40 ↓ (0.44 → 0.36) engagement 0.60 → (0.60 → 0.61) meditation 0.52 ↑ (0.47 → 0.57) mood 0.55 → (0.54 → 0.56) cognitive load 0.33 ↓ (0.38 → 0.28) drowsiness 0.10 → (0.11 → 0.09) ``` ### JSON Response Structure ```jsonc { "ok": true, "metrics": { "focus": 0.70, "relaxation": 0.40, "n_epochs": 541 // ... all ~50 metrics (see neuroskill-data-reference skill) }, "first": { "focus": 0.64, /* first-half averages */ }, "second": { "focus": 0.76, /* second-half averages */ }, "trends": { "focus": "up", // "up" | "down" | "flat" "relaxation": "down" // ... } } ``` ### Hidden Fields (visible only with `--full` or `--json`) | Hidden field | Contents | |---|---| | `first` | Every metric averaged over the **first half** of the session | | `second` | Every metric averaged over the **second half** | | `trends` | Direction string (`"up"` / `"down"` / `"flat"`) for every metric key | | `metrics` | All ~50 metric fields — summary only prints a curated subset | ```bash npx neuroskill session 0 --json | jq '.metrics' # all metric averages npx neuroskill session 0 --json | jq '.trends' # all trend directions npx neuroskill session 0 --json | jq '{f1: .first.focus, f2: .second.focus}' npx neuroskill session 0 --json | jq '[.trends | to_entries[] | select(.value == "up") | .key]' ``` --- ## `sessions` — List All Sessions List every recorded session across all days. Sessions are contiguous embedding ranges (gap threshold: 120 seconds between epochs). ```bash npx neuroskill sessions npx neuroskill sessions --json npx neuroskill sessions --json | jq '.sessions | length' npx neuroskill sessions --json | jq '.sessions[0]' npx neuroskill sessions --json | jq '[.sessions[] | {day, dur: (.end_utc - .start_utc)}]' npx neuroskill sessions --trends # show per-session metric trends ``` **HTTP:** ```bash curl -s -X POST http://127.0.0.1:8375/ \ -H "Content-Type: application/json" \ -d '{"command":"sessions"}' ``` ### Example Output ``` ⚡ sessions 3 session(s) 20260223 2/23/2026, 9:15:00 AM → 10:02:33 AM 47m 33s 570 epochs 20260223 2/23/2026, 2:30:00 PM → 3:12:45 PM 42m 45s 513 epochs 20260224 2/24/2026, 8:00:00 AM → 8:45:10 AM 45m 10s 541 epochs ``` ### JSON Response ```jsonc { "command": "sessions", "ok": true, "sessions": [ { "day": "20260224", "start_utc": 1740412800, // Unix seconds — newest first "end_utc": 1740415510, "n_epochs": 541 }, { "day": "20260223", "start_utc": 1740380100, "end_utc": 1740382665, "n_epochs": 513 } ] } ``` > **Getting Unix timestamps for other commands:** > ```bash > npx neuroskill sessions --json | jq '{start: .sessions[0].start_utc, end: .sessions[0].end_utc}' > ```
