Sprint Summary Skill for Claude

> Summarize a sprint's worth of Claude Code activity — sessions grouped by project (cwd), per-model cost breakdown, token efficiency (cache hit rate, compaction baselines), subagent effectiveness from workflow API, velocity metrics (turn_count, turn_duration_ms), and tool diversity across the sprint.

Sprint Summary

Generate a sprint summary from Claude Code Agent Monitor data.

Input

The user provides: $ARGUMENTS

This may be:

A sprint duration: "last 2 weeks", "last 10 days"
A date range: "2025-03-31 to 2025-04-13"
"current sprint" (default: last 14 days)

Procedure

Fetch sprint data from http://localhost:4820:
GET /api/sessions?limit=500 — all sessions in range (default sort: most recently updated first)
GET /api/analytics — aggregated metrics
GET /api/pricing/cost — total costs
For high-value sessions: GET /api/events?session_id={id} — event details

Compile sprint summary:

🎯 Sprint Overview

Sprint period: [start] to [end]
Total sessions: N (completed: N, errored: N, abandoned: N)
Total development hours with Claude Code: N
Total cost: $X.XX
Overall completion rate: N%

📦 Deliverables

Group sessions by working directory (project):

Project A (/path/to/project)
N sessions, N hours, key activities
Project B (/path/to/other)
N sessions, N hours, key activities

📊 Velocity Metrics

|--------|--------|-----------------|-------|

| Sessions/day | N | N | ↑/↓ |

| Avg session duration | Nm | Nm | ↑/↓ |

| Cost/session | $N | $N | ↑/↓ |

| Tokens/session | N | N | ↑/↓ |

Skill Creator

by anthropics

vendor ×10

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Replace with description of the skill and when Claude should use it.

Dispatching Parallel Agents

by ZhanlinCui

×5

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

Use when creating new skills, editing existing skills, or verifying skills work before deployment

How to use it

Copy the folder

Take hoangsonww/sprint-summary from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
