sprint-start

sprint-start is a skill for Claude Code from joris887/exosuit. It costs 33 tokens per session (2,591 once invoked), scanned A, original, MIT.

A workflow for preparing a new sprint, a short planned period of development work. It checks the project's current state, creates a feature branch, defines the sprint's goal and scope, and writes a sprint specification.

In plain words
What is it for?
Use it to run pre-sprint checks, confirm the correct default branch, create the sprint branch, and document the work planned for the sprint.
Why use it?
It catches open pull requests, uncommitted changes, or an outdated branch before new work starts. This gives the sprint a recorded plan and a clean starting point.

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-start 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.

Profile-Adaptive Behavior

Read the **Profile:** line from CLAUDE.md to determine the active project profile.

1. Pre-flight Checks

Verify the workspace is ready for new work:

1a. Check for open PRs

gh pr list --author @me --state open

If open PRs exist:

  • Check if any are approved → merge them: gh pr merge --squash --delete-branch
  • If awaiting review → inform user and ask whether to proceed or wait

1b. Verify clean working tree

git status

If uncommitted changes exist:

  • Warn user — they must commit, stash, or discard before proceeding
  • Do NOT proceed with dirty working tree

1c. Ensure on default branch and up to date

Read the Default branch from CLAUDE.md's Git Workflow section. If not set, detect it at runtime:

# Read from CLAUDE.md first, fall back to detection
DEFAULT_BRANCH=$(grep -oP '^\- \*\*Default branch:\*\* \K\S+' CLAUDE.md 2>/dev/null)
if [ -z "$DEFAULT_BRANCH" ]; then
    DEFAULT_BRANCH=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@')
fi
if [ -z "$DEFAULT_BRANCH" ]; then
    for branch in main master develop; do
        if git show-ref --verify --quiet "refs/heads/$branch"; then
            DEFAULT_BRANCH="$branch"
            break
        fi
    done

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.
