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.

SkillSpector: 5 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.10344 |
| Opus 5.5 | $0.00021 | $0.04138 |
| Sonnet 5.5 | $0.00010 | $0.02069 |
| Haiku 4.5 | $0.00005 | $0.01034 |
Grade A, and why
alive:demo 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 1mo 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 — 771 lines — stays where its author put it; the contents beside it link to each section on GitHub.
alive:demo -- generative demo-world skill
This is the router. Route on $ARGUMENTS[0] to a sibling .md file (when present) or to the interactive create flow. Six subcommands + an interactive default:
$ARGUMENTS[0] |
Routes to | Status |
|---|---|---|
empty / create |
Interactive: preset vs. custom; create.md for the custom path |
wired |
list |
list.md |
wired |
activate <ref> |
activate.md |
wired |
deactivate |
deactivate.md |
wired |
delete <ref> |
delete.md |
wired |
status |
status.md |
wired |
reset |
rebuilds demo-state.json (recovery from schema mismatch) | wired |
spike-test |
retired (fn-2-2zz.1 spike) | removed below |
All five non-create sibling .md files (list.md, activate.md, deactivate.md, delete.md, status.md) invoke their CLI subcommand under $ALIVE_PLUGIN_ROOT/bin/alive demo <name> and print the CLI's rendered_block field verbatim. create.md is the custom-path orchestrator: it walks Stage 0 -> Stage 1 hand-off -> Stage 2/3/4/5 driver chain end-to-end. The interactive default below routes the human into either the preset path or create.md based on their pick.
The router emits bordered blocks INLINE as markdown — matches the convention in plugins/alive/skills/world/SKILL.md and plugins/alive/skills/save/SKILL.md. There is no Python render_block bridge: the LLM emits its own markdown; only the CLI uses lib.format_block (per the codex review which rejected forcing LLM formatting from Python).
User choices use AskUserQuestion, never inline 1. / 2. / 3. answer text. Numbered options inside a bordered block are advisory; the actual decision flows through the question tool.
State + paths (canonical)
| Concern | Path | Override? |
|---|---|---|
| Demo state file | ~/.config/alive/demo-state.json |
NO. Tests set HOME to tmp_path. |
| Demo state lock | ~/.config/alive/.demo-state.lock |
NO. |
| World-root pointer | ~/.config/alive/world-root |
NO — owned by _world_root_io.write_world_root_file (#64). |
| Demo worlds + partials | ~/.alive-demos/ |
YES via $ALIVE_DEMO_BASE_DIR. |
What ships with it
42 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
- 1mo ago First seen · 771 lines · 52 tokens per session scan A 759e4ed2ddbe
alive:demo is a skill published in the GitHub repository alivecontext/alive (130 stars, last pushed 16d ago), licensed MIT. It adds 52 tokens to every session and 10,344 once invoked, about $0.0002 per session on Opus 5.5. 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.
Other skills, from other repositories
crit-cli
Use when an agent needs to author or reply to crit inline comments programmatically (including multi-agent workflows commenting on shared code/plans/docs/proposals), publish or unpublish a crit review with crit share, sync a crit review to or from a GitHub PR or GitLab MR, or read/interpret a crit review JSON file.…
crit
Review code changes, a plan, a live page (running dev server), or a local HTML file with Crit inline comments and structured human feedback. Use only when the user explicitly invokes /crit or directly asks to use Crit; a generic review request does not count.
crit-story
Author a crit story and continue the interactive review loop only when the user explicitly invokes crit-story or directly asks you to generate a crit story. Do not infer this skill from generic review, PR, or diff-review requests.
fresh-start
Continue in a new chat without losing anything — writes a compact handoff to paste into a fresh conversation. Use whenever the user wants to move to a new chat or conversation, hits usage limits, says replies got slow or Claude forgets earlier details, or the conversation has grown long.
token-check
Estimate how many tokens a pasted text, an attached file or the conversation so far takes, what it means for the context window and usage limits, and how to cut it. Use when the user asks how big something is in tokens, why they keep hitting limits, or whether a file is too large to send.
doc-digest
Turn a long document, PDF, transcript, spreadsheet or log into a compact working digest the conversation can continue from. Use when the user shares or pastes something long (several pages or more) and wants to discuss, analyze, compare or use it over more than one message, or asks to summarize a document so they can…
