retrospective

retrospective is a skill for Claude Code, Codex from omnigentx/jarvis. It costs 11 tokens per session (296 once invoked), scanned A, original, MIT.

A template and process for writing a sprint retrospective, a short review of what went well, what went wrong, and what the team should change after a period of development.

In plain words
What is it for?
Use it after a sprint to record successes, problems, team suggestions, key learnings, and assigned actions in a retrospective file.
Why use it?
It turns experience from completed work into specific lessons and follow-up actions instead of leaving improvements undocumented.

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

retrospective 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.

Template

# Retrospective — <Your Agent Name>

## What Went Well
- <Specific things that worked effectively>
- <Reference actual work done, files created, decisions made>

## What Could Be Improved
- <Specific challenges encountered>
- <Things that slowed you down or caused rework>

## Suggestions for the Team
- <Process improvements>
- <Communication improvements>
- <Tool or workflow suggestions>

## Key Learnings
- <Technical insights gained during this sprint>
- <Patterns to reuse in future sprints>
- <Anti-patterns to avoid>

## Action Items for Next Sprint
| # | Action | Owner |
|---|--------|-------|
| 1 | <specific improvement> | <agent name> |

Guidelines

  • Be specific — reference actual files, decisions, and outcomes from the workspace
  • Be honest — constructive criticism helps the team improve
  • Be actionable — every "could be improved" should have a suggestion
  • Read others' work — check workspace files to understand what the full team accomplished
  • Don't blame — focus on processes, not people

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.
