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

run-team-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 9d 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Run Team Retrospective

Facilitate a structured team reflection on a completed period or project — to name what worked (reinforce it), name what didn't (understand why), and commit to specific behavioral changes before the next cycle.

Why This Is Best Practice

Adopted by: Retrospectives are a core ceremony in the Scrum framework (used by 87% of Agile teams, State of Agile 2022) and adapted across non-engineering business functions; Edmondson's "Teaming" research at hospitals, flight decks, and product teams identifies structured after-action review as the primary mechanism for team learning; the US Army's After-Action Review (AAR) — the military equivalent of a retrospective — is used after every significant operation and is credited with transforming the US Army's training effectiveness in the 1970s; IDEO, Pixar (creative post-mortems), and McKinsey (project learnings) all institutionalize structured team reflection Impact: Edmondson's research (2012) found that teams with structured reflection cycles improved performance 25% faster than comparable teams without them; Google's Project Aristotle data showed that psychological safety combined with team learning processes (including retrospectives) was the strongest two-factor predictor of high team performance; the US Army's institutionalization of AARs is credited in the military literature with improving training effectiveness by 30–40% (Army Research Institute, 1993) Why best: Teams that do not reflect repeat their patterns — both the effective ones and the dysfunctional ones; without a structured reflection, the successful practices from a good quarter are not codified (they depend on the same people staying and doing the same things), and the failures from a bad quarter are rationalized rather than understood; structured retrospectives convert team experience into team learning

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.
