What it does

Retro is an agent skill from joa23/linear-cli. Analyze completed Linear cycles for retrospectives. Identifies velocity trends, scope creep, and patterns to improve future planning.

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering Retrospectives. The repository describes itself as: A token-efficient CLI for Linear. The licence is MIT.

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

Gather Cycle Data
Analyze Completion
Identify Patterns
Generate Insights

What it can do on your machine

Read from SKILL.md and the folder at commit 575c6f0. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Retro loads about 790 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 195 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~35
When it runs · the whole SKILL.md, loaded when a task matches: ~790

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Retro Skill - Sprint Retrospective

You are an expert at analyzing completed sprints and generating actionable retrospective insights.

When to Use

Use this skill when:

A sprint/cycle has ended
Preparing for a retrospective meeting
Analyzing team performance trends

Process

Gather Cycle Data

bash

linear cycles analyze --team ENG --count 3
linear cycles get CYCLE-ID

Analyze Completion
- Planned vs actual completion
- Scope changes during cycle
- Carry-over items
Identify Patterns
- Estimation accuracy
- Blocker frequency
- Category distribution
Generate Insights

Analysis Areas

Velocity & Completion

Points planned vs completed
Issue count planned vs completed
Completion rate trend

Scope Management

Issues added mid-cycle
Issues removed/deferred
Scope creep percentage

Blockers & Dependencies

Issues that were blocked
Average time blocked
Dependency-related delays

Workload Distribution

Points per team member
Completion rate by assignee
Bottleneck identification

Output Format

RETROSPECTIVE: Cycle 23
════════════════════════════════════════

SUMMARY
────────────────────────────────────────
Planned: 40 points (12 issues)
Completed: 34 points (10 issues)
Completion Rate: 85%

SCOPE CHANGES
────────────────────────────────────────
Added mid-cycle: 3 issues (8 pts)
Removed: 1 issue (2 pts)
Carried over: 2 issues (6 pts)
Scope creep: 15%

WHAT WENT WELL
────────────────────────────────────────
+ Auth refactor completed ahead of schedule
+ Zero critical bugs in production
+ Good collaboration on API work

WHAT COULD IMPROVE
────────────────────────────────────────
- 2 issues blocked for 3+ days (ENG-201, ENG-203)
- Underestimated ENG-205 (3pts planned, 8pts actual)
- Late scope additions disrupted focus

TRENDS (3 cycles)
────────────────────────────────────────
Velocity: 34 → 32 → 34 (stable)
Completion: 85% → 88% → 85% (stable)
Scope creep: 12% → 8% → 15% (increasing)

ACTION ITEMS
────────────────────────────────────────
1. Add buffer for complex API work
2. Daily standup check on blockers
3. Scope freeze after day 2

Commands Used

bash

# Analyze recent cycles
linear cycles analyze --team ENG --count 3

# Get specific cycle details
linear cycles get CYCLE-23

# List cycle issues
linear issues list --team ENG --cycle CYCLE-23

# Check what was blocked
linear deps --team ENG

Discussion Questions

Generate discussion prompts for the team:

Wins: What should we celebrate?
Blockers: What slowed us down?
Process: What would we do differently?
Tools: Are there tools/automation to add?
Communication: Where did we lose sync?

Best Practices

Be data-driven - Base insights on actual metrics
Focus on process - Not individual performance
Actionable items - Every insight should have a follow-up
Track over time - Compare to previous retros
