system-boot

An automatic startup routine that reads saved session memory and reports the current project, recent progress, known problems, and next step. It is designed for Evolving Lite, a system that tracks development-session context.

In plain words
What is it for?
Use it at session start, or when continuing or resuming work, to load project memory and display a compact status update.
Why use it?
It helps a returning session recover its context instead of starting without knowing what happened previously.

Or install evolving-lite, the plugin that ships this one along with the rest of its 2 skills, 16 commands, 6 agents, 6 hooks.

Per session 39 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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

system-boot 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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

System Boot

On every session start, perform this bootup sequence:

1. Read Memory

Read ${CLAUDE_PLUGIN_ROOT}/_memory/index.json for:

  • active_project: Which project the user was working on
  • last_session: When the last session was

If active_project is set, read ${CLAUDE_PLUGIN_ROOT}/_memory/projects/{active_project}.json for:

  • progress: Array of recent progress entries
  • next_step: What was planned next
  • failures: Known blockers or failures

2. Orient

Based on memory:

  • What was the last progress entry?
  • Are there any known failures or blockers?
  • What was suggested as the next step?

3. Announce

Output a compact status line:

Evolving Lite | Session {n} | Tier {tier} | {experience_count} experiences
Last: {last_progress_summary}
Next: {next_step}

If this is the first session ever (no progress), announce with a short, visible cold-start sequence so the system does not feel inert on day 1:

Evolving Lite v1.0 | First session
  [1/3] Loading {prewarmed_count} pre-warmed experiences ... ok
  [2/3] Tier 1 (Safety) active: context warnings, bash security, hook sentinels
  [3/3] Self-Star Doctor: wiring verified (run /health for the full board)
Ready. The system learns from your corrections automatically and self-tunes its
delegation routing from your sessions (see "Self-Evolution is ON" in the README).

The Self-Star Doctor also runs a quick wiring + preflight check automatically on this first session. If it reports a missing prerequisite (most often Kairn), surface that to the user and point them at /health and pip install kairn-ai.

4. Pick One Task

If the user hasn't specified what to work on, suggest the next_step from memory. Don't start multiple tasks - pick one.

Continue Trigger

When the user says "continue", "weiter", "weitermachen", "fortsetzen", or "resume":

  1. Read the most recent session summary from ${CLAUDE_PLUGIN_ROOT}/_memory/sessions/
  2. Load the plan if one was referenced
  3. Continue immediately - no questions, just pick up where we left off

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.

system-boot is a skill published in the GitHub repository primeline-ai/evolving-lite (48 stars, last pushed 16d ago), licensed MIT. It adds 39 tokens to every session and 600 once invoked, about $0.0002 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.
