Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.00370 |
| Opus 5 | $0.00011 | $0.00185 |
| Sonnet 5 | $0.00004 | $0.00074 |
| Haiku 4.5 | $0.00002 | $0.00037 |
Grade A, and why
avadakedavra scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Avada Kedavra — Session Kill & Transfer
Kills the current session and transfers full context to a fresh Opus instance. The user clicks ONE button and the new session continues seamlessly.
Steps
-
Capture session state — Run the capture script. This is MANDATORY before anything else:
REMEMBRALL_ROOT="${CLAUDE_PLUGIN_ROOT:-$(cat /tmp/remembrall-meta/plugin-root 2>/dev/null)}" source "${REMEMBRALL_ROOT}/hooks/lib.sh" CWD=$(pwd) SESSION_ID="${CLAUDE_SESSION_ID:-$(remembrall_read_session_id "$CWD" 2>/dev/null)}" bash "${REMEMBRALL_ROOT}/scripts/avadakedavra-capture.sh" --cwd "$CWD" --session-id "$SESSION_ID" -
Output exactly this and NOTHING else:
Avada Kedavra!
-
Call EnterPlanMode immediately. Do NOT add any text before or after step 2. Do NOT explain what you are doing. Do NOT plan. Do NOT summarize the session. Just the message and the tool call.
CRITICAL RULES
- Output ZERO text other than "Avada Kedavra!" — no explanations, no summaries, no "I'll now...", no "Let me..."
- Call EnterPlanMode IMMEDIATELY after the message
- Do NOT write a plan file
- The capture script handles ALL state saving — you do NOT need to create a handoff
- This skill exists to be FAST. The entire execution should take under 3 seconds of Claude output.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

avadakedavra is a skill published in the GitHub repository cukas/remembrall (6 stars, last pushed 5mo ago), licensed MIT. It adds 22 tokens to every session and 370 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
alive:system-cleanup
The world feels messy. Stale tasks, orphan folders, v2 remnants, unsaved sessions — entropy is accumulating and needs to be addressed before it compounds. Scans across all walnuts, then surfaces issues one at a time.
alive:world
The human doesn't know what to work on, or wants to see everything at once. They need the big picture — what's active, what's stale, what needs attention. Renders a live world view grouped by ALIVE domain, then routes to open, tidy, find, history, or map.
alive:bundle
Create, share, and graduate bundles — the unit of focused work within a walnut. Manages the full bundle lifecycle from creation through sharing to graduation.
alive:settings
The human wants to adjust how the system behaves — not what it contains, but how it feels. Voice, rhythm, preferences, walnut-level config, full permissions toggleable, named squirrel config, action logging toggle. The system adapting to them. Routes to preferences.yaml or walnut config.yaml depending on scope. For…
cco-budget
Configure token budget limits, auto-compact settings, and view current budget status (model-aware — Claude 5 lineup, Opus 5 default fallback, full 1M context at standard price).
alive-cleanup
System maintenance -- stale tasks, orphan folders, unsaved sessions, world health check.
