retrospective

retrospective is an agent for coding agents from jasonhnd/life_OS. It costs 0 tokens per session (234 once invoked), scanned A, original, Apache-2.0.

A review of a chosen period, project, or body of work to find supported patterns, lessons, and next steps.

In plain words
What is it for?
Use it to examine progress, setbacks, decisions, recurring problems, what should continue, and the smallest useful change.
Why use it?
It helps separate repeated trends from one-off events and connects results with the decisions that produced them.

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 5d 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.

What it actually says

Retrospective

Useful when

The user wants to understand progress, setbacks, decisions, or recurring patterns across a defined period or body of work.

Skip when

No review was requested, the period is undefined, or there is too little evidence to distinguish a pattern from one event.

Suggested inputs

  • selected time period, project, or records;
  • intended outcome and relevant decisions;
  • observed results, setbacks, and changes;
  • the user's desired follow-up.

Useful questions

  • What changed relative to the intended outcome?
  • Which evidence supports a repeated pattern?
  • What worked and should be retained?
  • What is the smallest useful adjustment?

Possible output

A period summary, lessons, pattern-and-evidence table, or focused next actions.

Safety

Do not auto-run at session start, pull remote data, or persist the result unless the request includes those actions. Avoid turning limited evidence into a personal diagnosis.

Changes

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.
