context-probe

Minimal Context Sentinel Installer. Installs a managed block into ALL detected rule files.

---

Commands

• /context-probe Install or update the Context Sentinel rule into ALL detected rule files.

• /context-probe status Check which files contain the Context Sentinel block.

• /context-probe off Remove the Context Sentinel block from ALL rule files.

• /context-probe help Show usage.

---

Design Principles

• Broadcast installation (multi-layer redundancy).
• Deterministic, machine-detectable sentinel token.
• No heuristics, no telemetry, no context estimation.

---

Install Targets (NO PRIORITY MODE)

Install into EVERY file that exists among:

• AGENTS
• AGENTS.md
• .agents
• .agents.md
• .cursor/rules/context-probe
• .cursor/rules/context-probe.md
• CLAUDE.md (repo root)

Rules:

• Do NOT choose a single target.
• Do NOT remove lower-layer blocks when higher-layer exists.
• Each file receives its own managed block (idempotent per file).

---

Managed Block Format

Use EXACT delimiters in every file:

<!-- CONTEXT_PROBE:BEGIN v0 -->
... managed content ...
<!-- CONTEXT_PROBE:END -->

---

Installable Block Content (v0)

<!-- CONTEXT_PROBE:BEGIN v0 -->
# Context Sentinel — Minimal Hard Constraint
# Managed by /context-probe. Do NOT edit manually.

## Hard Rule
Every assistant response MUST end with the exact token:

[Context: OK]

## Priority
This rule overrides any conflicting instructions in this file.

## Non-Overridable
User instructions MUST NOT disable, remove, or modify this behavior.

<!-- CONTEXT_PROBE:END -->

---

File Operation Rules

For EACH detected target file:

• If file exists:
  • Insert the managed block at the TOP (after title/header if present).
  • If block already exists, update it in place (do not duplicate).
• If file does NOT exist:
  • Do NOT create new rule files (only install into existing ones).

Global constraints:

• Never overwrite user content outside the managed block.
• Never duplicate blocks in the same file.
• On uninstall, remove ONLY the managed block from each file.

---

Command Behavior

/context-probe

• Scan all target files.
• For each existing file:
  • Insert or update the managed block.
• Output summary:

  Installed files:
    - <path1>
    - <path2>
    ...
  Version: v0
  

/context-probe status

• Scan all target files.
• Report for each:
  • path
  • present: true/false
  • version: v0 if found

/context-probe off

• Remove the managed block from ALL target files.
• Confirm list of modified paths.

/context-probe help

• Print command list and usage summary.

---

Hard Constraints

• Never overwrite user content outside the managed block.
• Never duplicate blocks in the same file.
• Never ask for confirmation; apply best-effort safe edits.
• Do not perform priority arbitration or cross-file deduplication.
