Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00547 |
| Opus 5 | $0.00018 | $0.00273 |
| Sonnet 5 | $0.00007 | $0.00109 |
| Haiku 4.5 | $0.00004 | $0.00055 |
Grade A, and why
retro 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Start-Stop-Continue Retrospective
Run a focused retrospective identifying what to Start, Stop, and Continue.
Instructions
Analyze the subject (project, period, process) and generate specific, actionable items for each category. Focus on behaviors and practices, not people.
Output Format
Subject: What period or topic are we reflecting on? Timeframe: What period does this cover?
START
New practices or behaviors to begin
| What to Start | Why | Owner | When |
|---|---|---|---|
| [Specific action] | [Benefit expected] | [Who] | [Start date] |
| [Specific action] | [Benefit expected] | [Who] | [Start date] |
| [Specific action] | [Benefit expected] | [Who] | [Start date] |
STOP
Current practices to eliminate
| What to Stop | Why | Owner | When |
|---|---|---|---|
| [Specific thing to stop] | [Problem it causes] | [Who] | [End date] |
| [Specific thing to stop] | [Problem it causes] | [Who] | [End date] |
| [Specific thing to stop] | [Problem it causes] | [Who] | [End date] |
CONTINUE
Things that are working well
| What to Continue | Why It Works | How to Protect It |
|---|---|---|
| [Working practice] | [Value it provides] | [How to ensure it continues] |
| [Working practice] | [Value it provides] | [How to ensure it continues] |

Guidelines
- Be specific: "Start daily standups" not "communicate more"
- Be behavioral: Focus on actions, not attitudes
- Balance: Aim for 3-5 items per category
- Celebrate Continues: Don't skip this section—recognize what's working
- Assign owners: Unowned actions don't happen
- One priority: If everything is important, nothing is
$ARGUMENTS
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.

retro is a skill published in the GitHub repository neurofoo/agent-skills (111 stars, last pushed 7mo ago), licensed MIT. It adds 37 tokens to every session and 547 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
