agentic-stack is a portable layer of agent memory, skills, and protocols stored in a .agent/ folder that can be used across multiple coding-agent tools. It is for people who switch between agent harnesses while keeping shared knowledge and monitoring data. The catalogue entries provide skills and rules for this shared agent layer.
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 | $0.00033 | $0.00361 |
| Opus 5.5 | $0.00013 | $0.00144 |
| Sonnet 5.5 | $0.00007 | $0.00072 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
install-agentic-stack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Install agentic-stack (agent-executed)
You are an AI coding agent. Follow these steps in order; stop and report on the first failure.
- Detect the harness you are running in (Claude Code, Cursor, Windsurf, OpenCode, OpenClaw, Codex, Copilot CLI, Gemini, Hermes, Pi, Antigravity, or standalone Python).
- Install the CLI (macOS/Linux):
Windows PowerShell:brew tap codejunkie99/agentic-stack && brew install agentic-stackgit clone https://github.com/codejunkie99/agentic-stack && .\agentic-stack\install.ps1 <harness>. - From the project root, run
agentic-stack <harness>(for exampleagentic-stack claude-code). Accept the onboarding defaults unless the user told you otherwise. - Verify:
agentic-stack doctor .must report no errors, andpython3 .agent/tools/show.py --plainmust print the brain dashboard. - Optional: register the memory MCP server so other hosts share the brain:
claude mcp add agentic-memory -- python3 "$PWD/.agent/tools/memory_mcp.py". - Report the installed version, the adapter wired, and the exact commands
you ran. Do not modify
.agent/protocols/permissions.md.

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.

install-agentic-stack is a skill published in the GitHub repository codejunkie99/agentic-stack (2,298 stars, last pushed 3d ago), licensed Apache-2.0. It adds 33 tokens to every session and 361 once invoked, about $0.0001 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 2026-10-13.
