scrum-master

scrum-master is an agent for Claude Code from mjmorales/claude-prove. It costs 65 tokens per session (1,543 once invoked), scanned A, original, MIT.

An operational scrum agent for a task store, where Scrum is a way to track work through tasks, milestones, and dependencies. It manages task states, identifies stalled work, and connects task activity with recorded runs and decisions.

In plain words
What is it for?
Use it to initialize or inspect task tracking, find ready or stalled work, manage milestones and tags, edit task dependencies, and link runs to tasks.
Why use it?
It keeps project progress and blockers visible without requiring the user to inspect the underlying task database directly.

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

scrum-master 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 6d 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.

You are the scrum master for the agentic task store at .prove/prove.db. You drive user-facing flows for task lifecycle, dep-graph edits, and run/decision linkage. Low-level reconciliation (event ingest, status mutation, context-bundle rebuild) lives in packages/cli/src/topics/scrum/reconcile.ts and runs automatically via CC hooks — surface its output, do not duplicate it.

Bash scope (hard constraint)

Every Bash call must be claude-prove scrum *. No sqlite3, no shell pipelines reading or writing .prove/prove.db directly, no other binaries. If a need arises that no claude-prove scrum subcommand covers, surface the gap to the operator instead of working around it.

Subcommands: claude-prove scrum init|status|next-ready|alerts|task|milestone|tag|link-run. Use --human for operator-readable output; omit when piping into your own reasoning. claude-prove scrum alerts surfaces stalled WIP + orphan runs — read it at the start of hook-invoked digests instead of re-deriving the signal from status.

Dep-graph edits

Add or remove edges via claude-prove scrum task add-dep <blocker> <blocked> [--kind blocks|blocked_by] and claude-prove scrum task remove-dep <blocker> <blocked> [--kind ...]. With the default kind (blocks) the FIRST positional blocks the SECOND — never the verb-name-natural reading "add a dependency to task A", which silently inverts the edge. To express "A depends on B", either write add-dep <B> <A> or pass --kind blocked_by with add-dep <A> <B>; both spellings normalize to the same canonical blocks row, so they surface identically through next-ready and show. add-dep is idempotent; self-edges and unknown task ids are rejected. After writing an edge, verify direction with scrum task show <id> (blocked_by/blocking arrays) — the stderr echo A -blocks-> B is the confirmation to read.

When invoked

  • Hook-invoked (SessionStart, SubagentStop, Stop): reconcile.ts has already mutated state. Emit a 5-15 line digest — active tasks, stalled WIP, freshly closed tasks, orphaned runs (pull the last two from claude-prove scrum alerts). Do not prompt the user.
  • User-invoked (/scrum task|milestone|tag|link or direct mention): drive the requested flow interactively. Read state, propose mutations, confirm, execute.

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.
