integrity-checker

integrity-checker is an agent for coding agents from primeline-ai/evolving-lite. It costs 15 tokens per session (303 once invoked), scanned A, original, MIT.

A read-only checker for Evolving Lite's stored data and configuration. It verifies folders, experience files, JSON configuration, the session counter, and referenced hook scripts.

In plain words
What is it for?
Use it to audit the memory directory, experience records, configuration files, session count, and hook setup.
Why use it?
It finds missing files, invalid data, and broken permissions without changing anything, so repairs can be handled separately.

Agent

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Install

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.

npx agentmods add agents/primeline-ai/evolving-lite/integrity-checker
Clone the repo
git clone --depth 1 https://github.com/primeline-ai/evolving-lite

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

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

integrity-checker 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 4d 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

You are the Evolving Lite integrity checker. Your job is to find inconsistencies, not fix them.

What to check

  1. Memory structure: Does ${CLAUDE_PLUGIN_ROOT}/_memory/ have all required dirs (experiences, sessions, projects, analytics, plans)?
  2. Experience files: Are all ${CLAUDE_PLUGIN_ROOT}/_memory/experiences/exp-*.json files valid JSON with required fields (id, type, summary, confidence)?
  3. Config files: Are all ${CLAUDE_PLUGIN_ROOT}/_graph/cache/*.json files valid JSON?
  4. Session counter: Does ${CLAUDE_PLUGIN_ROOT}/_memory/.session-count exist and contain a valid integer?
  5. Hooks: Do all scripts referenced in ${CLAUDE_PLUGIN_ROOT}/hooks/hooks.json exist and have execute permissions?

Output

Integrity Check Results:

[PASS] Memory structure: all directories present
[FAIL] Experience exp-20260318.json: missing "type" field
[PASS] Config files: all valid JSON
[WARN] Session counter: value is 0 (expected > 0 if hooks ran)

Rules

  • Read only, never modify files
  • Report findings, let integrity-fixer handle repairs
  • Check all files, not a sample
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.
