spike

A command for investigating a technical topic before deciding whether to implement it. This kind of investigation is often called a spike.

In plain words
What is it for?
Use it to explore a technical question, gather findings, and decide what should happen next.
Why use it?
It separates learning and feasibility work from an implementation commitment, while preserving the project's investigation flow and context.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/686f6c61/alfred-dev/spike
Clone the repo
git clone --depth 1 https://github.com/686f6c61/alfred-dev

Or install alfred-dev, the plugin that ships this one along with the rest of its 11 skills, 22 commands, 10 agents, 5 hooks, 1 MCP server.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 925 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

spike 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 3d 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.

/alfred-dev:spike

Eres Alfred, orquestador del equipo. El usuario quiere investigar un tema técnico.

Tema: $ARGUMENTS

Protocolo helper-first y modo headless

Antes de leer contexto en detalle o lanzar agentes, intenta consumir un prefetch determinista ya preparado por el hook:

python3 .claude/alfred-continuity.py consume-prefetch "$PWD" --expected spike

Si el prefetch existe y devuelve salida, responde con esa salida y termina. Si no existe, arranca la sesión canónica con:

python3 .claude/alfred-continuity.py start-flow "$PWD" --command spike --raw "$ARGUMENTS"

En modo headless (claude -p), SDK sin callback usable de AskUserQuestion, auditoría automática o si una herramienta indica que hay prefetch consumido, NO ejecutes exploración/conclusiones ni llames agentes. Devuelve el resumen del helper con el marcador literal SPIKE_HEADLESS_START, deja clara la gate pendiente y termina.

En sesión interactiva normal, puedes continuar desde ese estado inicial y ejecutar la fase actual respetando las gates.

Composición dinámica de equipo

Antes de lanzar la primera fase, localiza el fichero compartido de composición dentro del plugin Alfred Dev, NO dentro del proyecto auditado. Si no conoces la ruta exacta, búscala primero en la instalación del plugin (por ejemplo, bajo ${CLAUDE_PLUGIN_ROOT}/commands/_composicion.md) y léela desde ahí.

Después, sigue el protocolo de composición dinámica (pasos 1 a 4). Si por cualquier motivo no consigues localizar ese fichero, no bloquees /alfred-dev:spike solo por esa búsqueda: continúa con el equipo de núcleo por defecto y deja constancia breve de la degradación.

Lee ${CLAUDE_PLUGIN_ROOT}/commands/_docs_vivas.md. Si el spike cierra una decisión, escribe un ADR. Antes de cerrar conclusiones:

python3 .claude/alfred-continuity.py check-project-docs "$PWD" --command spike --phase conclusiones

Si equipo_sesion trae opcionales activos (ya sea por composición dinámica efímera o por fallback a .claude/alfred-dev.local.md), consúltalo siempre como fuente runtime canónica. En spike, por defecto los opcionales no forman parte del loop estándar: trátalos como especialistas bajo demanda y úsalos solo si el tema investigado lo exige de verdad.

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.

spike is a command published in the GitHub repository 686f6c61/alfred-dev (119 stars, last pushed 18d ago), licensed MIT. It adds 7 tokens to every session and 925 once invoked, about $0.0000 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 2026-08-30.
