retrospective

retrospective is a skill for Claude Code, Codex from omnigentx/jarvis. It costs 21 tokens per session (506 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 14d 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 — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Retrospective

Use after an accepted milestone or a significant failure/rework checkpoint. Idle is not completion. A retrospective may happen while delivery remains incomplete; it does not authorize acceptance or a Jira Done transition.

Coordinate a focused discussion

Check existing meetings and Jira for this checkpoint before creating another. Reuse the existing retrospective and action items on retries. Invite only owners involved in the decision; avoid an all-team meeting for a single tool failure.

Use create_meeting(agenda="Retrospective — <checkpoint>", participants="<actual agent names>", description="<evidence links, decision needed>", max_rounds=2). Get actual names from the current team, not example rosters. The creator is included automatically. Present findings before issuing a separate verdict after participants have contributed or absences are explicitly recorded.

Discuss evidence, root cause, what worked, and one measurable change. Separate observed facts from hypotheses. Publish the summary in Confluence; link actionable Jira tasks with owner, acceptance criteria and measurement. Workspace notes are drafts, not durable memory.

Learn within each agent's scope

Each owner proposes their own reusable lesson through memory_server procedure_propose(title, steps). The tool binds the caller identity: never impersonate another owner or store a team observation as a user preference.

Include in steps:

  • Trigger/context where this workflow applies.
  • Evidence and root cause; limits of what was actually verified.
  • Concrete steps, verification and stopping conditions.
  • Jira/Confluence evidence references and review date.

Use one concise procedure per distinct lesson. Search your existing procedural memories first and reuse an equivalent lesson. Do not persist transcripts, temporary assignments, credentials, raw tool dumps or unsupported claims. Cross-agent/global promotion requires separate user review.

A returned candidate ID with pending status means proposed, not learned or applied. Approval is mandatory for procedure proposals. If memory is disabled or unavailable, record the unresolved action on Jira; do not claim persistence.

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.
