context-scribe AGENTS.md

A set of AGENTS.md instructions for Context-Scribe, a background service that watches AI logs and stores lasting rules and preferences in a searchable memory bank.

In plain words
What is it for?
Use it to guide Context-Scribe setup, define agent roles, require memory retrieval at the start of sessions, and apply its latest-rule-wins policy.
Why use it?
It tells agents how to load project context before working and how to handle conflicts when stored rules change.

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

context-scribe AGENTS.md 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 2d 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.

AGENTS.md

1. Project Goal

Context-Scribe is a background daemon that monitors AI logs to extract persistent rules and stores them in an MCP-managed Memory Bank. It manages a Retrieval-Based memory system where agents are instructed to actively fetch their context.

2. Agent Personas

  • The Scribe: Silent observer. Monitors ~/.gemini/tmp/ for JSON log updates.
  • The Evaluator: Decision engine. Identifies new rules and performs Autonomous Conflict Resolution (New rules overwrite old ones in the bank).

3. Global Bootstrap Logic (User Level)

To ensure all sessions across all directories are "Memory-Aware," the tool ensures the following instruction exists in ~/.gemini/GEMINI.md (or the equivalent rule file for the specific tool):

Master Retrieval Directive: "You have access to a persistent Memory Bank via the memory-bank-mcp-server. Before beginning any task, you MUST invoke the appropriate tool (e.g., read_memory_bank) to identify current project constraints and user preferences. Do not assume you have full context until this check is complete."

4. Conflict Handling (State Management)

The system operates on a Latest-is-Truth model:

  1. Detection: Scribe detects a new instruction in logs.
  2. Comparison: Evaluator checks the Bank for contradictory rules.
  3. Resolution: If a conflict is found, the new rule replaces the old one.
  4. Log: The tool outputs [RESOLVE] Overwriting stale rule with new user preference.

5. Observability (The Heartbeat)

Real-time console feedback for background operations:

Event Level Output Example
Detection INFO [WATCH] Activity in ~/.gemini/tmp/chats/logs.json
Analysis INFO [THINK] Evaluating last exchange for persistent rules...
Conflict WARN [RESOLVE] New instruction 'Use Python 3.12' overwriting 'Use Python 3.10'
Commit ACTION [BANK] Update successful via MCP tool 'write_file'

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.
