boot

A command sequence that runs when a coding session starts. It loads saved project memory, checks rules, reviews recent session results, and reports unresolved violations.

In plain words
What is it for?
Use it to load learned rules, run their checks, inspect session history, identify violations, and confirm whether the session is ready.
Why use it?
It helps an agent begin with the right context and verify that required rules are being followed before work starts.

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.

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 B, and why

boot scanned grade B with 1 finding 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 yesterday.

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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

What it actually says

Load Memory

Learned Rules

!cat .claude/memory/learned-rules.md 2>/dev/null || echo "No learned rules yet"

Last Session Score

!tail -1 .claude/memory/sessions.jsonl 2>/dev/null || echo "No session history"

Unresolved Violations

!tail -5 .claude/memory/violations.jsonl 2>/dev/null || echo "No violations logged"

Instructions

  1. Read every rule in learned-rules.md. For each rule that has a verify: line, run the check NOW.
  2. Report results:
    • All pass → "All rules verified. Ready to work."
    • Any fail → list violations with file:line and specific fix.
  3. Check session trend: if sessions.jsonl has 5+ entries, report one-line trend (corrections increasing/decreasing, common violations).
  4. You are now primed. Proceed with the user's task.
Changes

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.

boot is a command published in the GitHub repository keysersoose/claude-code-setup (2 stars, last pushed 1mo ago), licensed MIT. It adds 18 tokens to every session and 230 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
