retrospect

retrospect is a skill for Claude Code, Codex from mikeprasad/aria-knowledge. It costs 158 tokens per session (13,797 once invoked), scanned A, original, no licence file.

A structured review of work that has already shipped, such as a commit range, release, deployment, pull request, commit, or session. It validates each fix, gathers evidence, checks simpler alternatives, and produces action decisions.

In plain words
What is it for?
Use it after delivering changes to investigate results, recheck diagnoses, validate fixes, and decide what to do next.
Why use it?
It helps determine whether shipped changes actually solved the problem and whether follow-up work is needed.

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

retrospect scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- **Bundle fetch + grep** — `Bash curl -s <deployed-bundle-url> | grep -F '<unique-marker-string>'`. The unique marker is either a function name from the diff, a comment string the fix added, or a `[<TAG>-DIAG]` instrume

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
