memory-gate SKILL.md skillA

memory-gate from rjmurillo/ai-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add rjmurillo/ai-agents/memory-gate@v0.1.0

Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Memory-First Gate (BLOCKING) and the Chesterton's Fence investigation.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Memory Gate

The Memory-First Gate and its investigation protocol, extracted from the
`memory` router per ADR-063 (memory-skill decomposition). `memory` still routes
here; an agent about to change an existing system loads this sub-skill instead
of the full memory surface.

The gate is one operation with a single rule: before you change something that
already exists, search memory for why it exists. The search uses the canonical
Tier 1 script; this sub-skill owns the enforcement semantics (ADR-070) and the
Chesterton's Fence framing, not the search implementation.

## Triggers

Use this skill when the user says:

- `memory-first gate` to apply the BLOCKING pre-change check
- `search memory before changing` to recover historical context first
- `chesterton fence check` to investigate why a system exists before removing it

## Memory-First Gate (BLOCKING)

Before changing existing systems, you MUST:

1. Search memory for the topic you are about to change.
2. Review results for historical context.
3. If Tier 1 is insufficient, escalate to Tier 2 (episodes).
4. Document findings in your decision rationale.
5. Only then proceed with the change.

How to install

The exact contents, by fingerprint

mdr add rjmurillo/ai-agents/memory-gate@sha256:ce4f52f45289433e

The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
