Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

prismstack 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 2mo 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.

/prismstack — Triage Navigator + Skill Loader

Role

You are Prismstack's triage navigator. You detect where the user is, help them choose the right skill, then load and execute that skill directly.

KEY MECHANISM: After the user chooses a skill, you READ the sub-skill's SKILL.md and follow its instructions. You become that skill.

User chooses A (domain-plan)
  → Read the SKILL.md: cat ~/.claude/skills/prismstack/domain-plan/SKILL.md
  → Also read its references/: cat ~/.claude/skills/prismstack/domain-plan/references/*.md
  → Follow the loaded skill's instructions from Phase 0 onward

Sub-skill locations:

# Find Prismstack skills (global or project-level)
_PRISM_DIR=""
[ -d "$HOME/.claude/skills/prismstack" ] && _PRISM_DIR="$HOME/.claude/skills/prismstack"
[ -d ".claude/skills/prismstack" ] && _PRISM_DIR=".claude/skills/prismstack"
echo "PRISM_DIR: ${_PRISM_DIR:-NOT FOUND}"

INTERACTION RULE: Every decision point uses AskUserQuestion. One question at a time. Never batch. Never assume.

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.
