spark

spark is a skill for Claude Code, Codex from a-lottes/aSPARK. It costs 73 tokens per session (1,827 once invoked), scanned A, original, MIT.

An orchestrator for the full SPARK development loop: Specify, Plan, Act, Review, and Keep. It coordinates the separate phases and pauses at decision gates so the user controls progress.

In plain words
What is it for?
Use it to start a new feature workflow or resume one in the `.spark/` directory. It determines the next phase from the feature's status records and coordinates the relevant ceremonies.
Why use it?
It gives a feature idea a defined path from planning through implementation, review, and release, while using recorded statuses to resume unfinished work.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

spark 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/spark — The Full Loop (Orchestrator)

You are conducting the entire SPARK loop for one feature. You don't do the phase work yourself — each ceremony's skill defines it. You sequence the ceremonies, enforce the gates, and keep the user in charge at every transition.

Input

  • With an idea as argument → start a fresh loop at Specify.
  • Without an argument → resume: pick the feature (single one in .spark/ → use it; several → ask the user), read its artifacts' statuses, and continue at the first phase whose gate is not yet closed (see the phase map below).
  • Without an argument, and no feature to resume (every existing feature is released, or .spark/ is empty) → don't guess an idea. Tell the user there's nothing to resume and offer /next-steps to have the Product Owner propose one from the project's current state, or ask them to bring their own idea.

The Phase Map

Determine the current position from artifact statuses in .spark/<feature-name>/ — from the statuses, not the artifacts. What places the loop is the Status row in each file's header table plus the Status column of the task table in plan.md. Grep for those or read the first few lines; a resume that reads a whole spec and plan to answer "which phase am I in" spends thousands of tokens on a five-line question, and it spends them in the context the rest of the loop still has to fit into.

Artifact state Next ceremony
no spec.md /story-time
spec.md is draft, UI-facing, design review empty /look-and-feel
spec.md is draft otherwise finish /story-time (approval)
spec.md approved, no/unapproved plan.md /sprint-plan
plan.md approved, tasks not all done /increment
tasks done, review.md missing or not passed /peer-review
review.md passed, qa.md missing or not passed /demo-day
review.md + qa.md passed, no released/handed-off release /go-live
release released loop closed — tell the user
release handed-off loop closed for this team — tell the user it's handed off, not yet approved elsewhere

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.

spark is a skill published in the GitHub repository a-lottes/aSPARK (19 stars, last pushed 4d ago), licensed MIT. It adds 73 tokens to every session and 1,827 once invoked, about $0.0004 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.
