sprint-plan

sprint-plan is a skill for Claude Code from a-lottes/aSPARK. It costs 63 tokens per session (1,000 once invoked), scanned A, original, MIT.

A planning step that turns an approved feature description into a technical plan for building it. It records architecture choices, ordered tasks, completion checks, tests, and risks.

In plain words
What is it for?
Use it after a feature specification is approved to choose an architecture, break the work into tasks, define when each task is done, plan testing, and note risks.
Why use it?
It prevents developers from having to make major design decisions while implementing the feature. It also stops work from starting when the feature description is still unfinished or unapproved.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

sprint-plan 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/sprint-plan — Plan (Engineering Manager)

You are running the Plan ceremony. The Engineering Manager locks the "how" so that /increment never has to invent architecture on the fly.

Input

Optional argument: the feature name. Resolve as usual (single feature in .spark/ → use it; several → ask).

Steps

  1. Check the gate. .spark/<feature-name>/spec.md must exist with status approved. If not, STOP and tell the user what's missing — /story-time or /look-and-feel come first. Never plan against a draft. The gate needs the spec's Status row, not the spec: the engineering-manager agent reads it whole in its own context, and a copy in this conversation would only crowd out the phases still to come.
    • Only after the gate has passed, resolve optional tool availability, once: if the session exposes MCP tools whose names end in staleness and impact (they are normally namespaced, e.g. mcp__aspark-graph__staleness), treat that as the available surface and run no command; otherwise probe once, read-only, with command -v aspark-graph >/dev/null 2>&1 && echo runner=yes || echo runner=no; test -f .aspark-graph/graph.json && echo graph=yes || echo graph=no — it reports both facts and always exits 0, so the absent case never looks like a failed command. Resolve both facts — is there a surface, and does .aspark-graph/graph.json exist — and act on the four states in ${CLAUDE_PLUGIN_ROOT}/tools/aspark-graph.md: pass the tool file in step 2 only when both hold; say its one-sentence hint, at most once, in either mixed state; and when neither holds, say nothing at all and continue exactly as you would otherwise. Never probe in a run that already stopped, and never let the outcome change a gate.
  2. Delegate to the Engineering Manager. Invoke the engineering-manager agent with the feature paths and the plan template from ${CLAUDE_PLUGIN_ROOT}/templates/plan.md. Point it at .spark/constitution.md if it exists — the architecture must live within its technical constraints. If a tool resolved as available in step 1, pass ${CLAUDE_PLUGIN_ROOT}/tools/aspark-graph.md too — one more path alongside the template, nothing else. For a plan revision (rework after /peer-review or /demo-day findings), pass those findings along and say explicitly that this is a revision.
  3. Relay questions. If the agent returns technical questions that change the architecture, put them to the user (AskUserQuestion for enumerable choices), then re-invoke with the answers.
    • The agent may also return a tool query request — it has no shell of its own. Run only the read-only query call it names, exactly as the tool file documents it, and re-invoke with the result. Never run a build, an install, or anything that writes. If the call fails or returns nothing, say so and let the agent proceed without it.
  4. Present the plan. Show the user: the architecture decision with the rejected alternatives, the task table (count, order, walking-skeleton start), the test strategy, and the top risks. This is the moment for the user to veto the approach — say so.
  5. Iterate on feedback via the agent until the user is satisfied.
  6. Close the gate. Walk the PLAN GATE checklist with the user. On their explicit approval: set the plan status to approved.

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.

sprint-plan is a skill published in the GitHub repository a-lottes/aSPARK (19 stars, last pushed 7d ago), licensed MIT. It adds 63 tokens to every session and 1,000 once invoked, about $0.0003 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.
