scenario

scenario is a command for Claude Code from marciopuga/cog. It costs 47 tokens per session (1,883 once invoked), scanned A, original, MIT.

A decision-simulation command that maps two or three possible paths from a specific choice, including dependencies, timing, and warning signs.

In plain words
What is it for?
It helps model “what if” situations, compare decision branches, and define signals that would show whether a path is working.
Why use it?
It makes the consequences and contingencies of a decision easier to compare using information already stored in memory.

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

scenario 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 4d 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 — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use this skill for scenario simulation — modeling decision branches with timelines, dependencies, and contingencies grounded in real memory data. Trigger if the user says "scenario", "what if", "model this", "simulate", "play out", "what happens if", or similar branching/decision-modeling requests. Also triggered when the foresight skill flags a scenario candidate in its nudge.

Memory Path

All files under the resolved memory path: $COG_HOME/memory/ if COG_HOME is set, otherwise ~/cog/memory/. All memory/... references below are relative to this root.

This is NOT foresight. Foresight = scan broadly, write one nudge. Scenario = take a specific decision point, branch it into 2-3 paths, map dependencies and timelines for each. Foresight finds the question. Scenario models the answers.

This is NOT reflect. Reflect = past-facing, mines interactions, improves memory. Scenario = future-facing, models possible futures from a decision point. Reflect checks old scenarios against reality (the feedback loop), but scenario creates them.

Domain

Cross-domain decision modeling — personal, work, projects, health, family. Scenarios are most valuable when a decision in one domain has cascading effects across others.

Memory Files

Read based on scenario topic — this is focused, not a broad scan:

  • memory/hot-memory.md (cross-domain strategic context)
  • memory/personal/calendar.md (upcoming timeline for overlay)
  • memory/personal/action-items.md (existing commitments, constraints)
  • Work domain action-items (read memory/domains.yml for active work domains)
  • Relevant domain hot-memory and entity files based on the scenario topic
  • memory/cog-meta/scenarios/ (existing scenarios — check for duplicates or related active scenarios)
  • memory/cog-meta/scenario-calibration.md (past accuracy — calibrate confidence accordingly)

Process

1. Decision Point Identification

From user input or foresight seed, identify the specific decision point. A valid scenario requires:

  • A fork — at least 2 meaningfully different paths forward
  • Stakes — the outcome matters enough that choosing wrong has real cost (time, money, relationships, health)
  • Uncertainty — the right choice isn't obvious from current information
  • Time sensitivity — the decision window is closing or the consequences unfold on a timeline

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.

scenario is a command published in the GitHub repository marciopuga/cog (376 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 1,883 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.
