Prismer Cloud is an infrastructure layer for AI agents that provides shared learning, compressed context, persistent memory, collaboration, messaging, tasks, identity, and workspaces. It is for agents and the people building or using long-running agent systems that need information and outcomes to persist across sessions. The catalogue entries provide skills, hooks, agents, instructions, and a plugin for using Prismer Cloud.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00023 | $0.00426 |
| Opus 5 | $0.00012 | $0.00213 |
| Sonnet 5 | $0.00005 | $0.00085 |
| Haiku 4.5 | $0.00002 | $0.00043 |
Grade A, and why
prismer-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Prismer Setup
Step 1: Check existing config
cat ~/.prismer/config.toml 2>/dev/null | grep api_key | head -1 || echo "No config found"
If already configured and user doesn't want to reconfigure, stop here.
Step 2: Run auto-setup
IMPORTANT: This command opens the browser and waits for the user to sign in. Set Bash timeout to 300000 (5 minutes):
node "${CLAUDE_PLUGIN_ROOT}/scripts/setup.mjs" --force
The script:
- Starts a local callback server
- Opens the browser to prismer.cloud/setup
- User signs in or registers → key auto-created → redirected back to localhost
- Key saved to
~/.prismer/config.toml
Wait for it to complete. It will print "API key saved" when done.
Step 3: Mark setup complete
CACHE="${CLAUDE_PLUGIN_DATA:-${CLAUDE_PLUGIN_ROOT}/.cache}"
mkdir -p "$CACHE"
echo "$(date +%s)" > "$CACHE/.setup-done"
Tell the user: "Setup complete! Run /reload-plugins to activate hooks."
Step 4: MCP Tools (optional)
Ask the user: "Do you also want MCP tools? These let Claude proactively call evolution/memory/skill APIs (29 tools). Without MCP, hooks still work (passive context injection). With MCP, Claude can actively create genes, write memory, search skills."
If yes:
claude mcp add prismer -- npx -y @prismer/[email protected]
If no: skip. Plugin works fine without MCP — hooks handle sync/journal/stuck-detection independently.
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.

prismer-setup is a skill published in the GitHub repository Prismer-AI/PrismerCloud (1,439 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 426 once invoked, about $0.0001 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.
Other skills, from other repositories
recall
Recall this repository's OwnMem local memory before changing code, and keep it healthy. Use when a repository contains .ownmem/, when past debugging lessons could apply ("have we hit this before", "why is it done this way"), or when the user mentions ownmem, project memory, or recalling across sessions.
init
Install or update OwnMem in the current repository. Use when the user asks to set up OwnMem, add local project memory for coding agents, or refresh an existing OwnMem installation after a version bump.
docmancer
Work from the same local memory as every other coding agent on this machine. Recall prior decisions, preferences, instructions, and project conventions that Claude Code, Codex, Cursor, and other agents wrote here, with cited sources, fully local. Also searches a separate local technical-documentation index.
linksee-memory
The bridge to the agent's "past self". Before any new task, file edit, decision, or right after a failure, recall past caveats (pain records) / learnings (growth log) / implementation history from linksee-memory. This is the only way to solve Claude Code's "memory amnesia every session" problem. The "never repeat the…
agent-prompts-warmup
Audit and sync agent instruction files across all coding agent formats. FRE (first-run) checks scaffolding completeness; ongoing use keeps files in sync after edits.
setup-bot
Diagnose and fix Telegram bot connection issues -- verify config, test send, resolve common errors.
