Preserve your grandfather's stories, skills, life philosophy, and the quiet strength that held the family together. He survived things you can't imagine. Fee...

Security Scan

The skill's files and instructions are generally consistent with preserving local memories, but an automated scan found prompt‑injection (unicode control characters) in SKILL.md and the phrase "Self-learning" is ambiguous — review before installing.

Purpose & Capability

Name/description (preserve a grandfather's memories) matches the instructions and declared requirements: no credentials, no external services, and local storage (~/.grandpa-skill/). There are no unrelated environment variables or binaries requested.

Instruction Scope

SKILL.md instructs the agent to collect manual user input and store it locally in human-readable files; it does not instruct reading other system files or sending data externally. However, the document uses the term "Self-learning" and contains a truncated example and formatting that could hide additional directives; combined with detected unicode-control characters, this warrants closer inspection of the raw SKILL.md for hidden/obfuscated content.

Install Mechanism

There is no install spec included (instruction-only), which is lower risk because nothing is automatically downloaded or executed. The README shows example install commands for package managers/agents, but those are invocation examples rather than an included install script.

Credentials

The skill requests no environment variables, no credentials, and no config paths. That aligns with its stated purpose of local-only memory storage.

Persistence & Privilege

always:false and default autonomous invocation are normal. The skill stores files under a user home directory (~/.grandpa-skill/), which is a reasonable scope for data persistence and not an elevated system privilege.

Scan Findings in Context

[unicode-control-chars] unexpected: Non-printing/unicode-control characters were detected in SKILL.md. These characters are not expected for a simple instruction document and can be used to obfuscate prompt-injection or hidden directives. This finding increases risk and should be inspected in the raw file (e.g., view hex or reveal control chars) before trusting the skill.

What to consider before installing

This skill appears to be what it claims (collect your memories and save them locally), but take these precautions before installing or using it: 1) Inspect SKILL.md and README in a raw/hex or 'show invisibles' view to confirm there are no hidden control characters or injected directives; the scanner found unicode-control-chars. 2) If you install, do so from a trusted source (verify the publisher's identity) and prefer installing in a sandboxed account or VM first. 3) Confirm what files are created under ~/.grandpa-skill/ and check their permissions; ensure no unexpected network activity (monitor outbound connections during first runs). 4) Ask the publisher to clarify what they mean by "Self-learning" — does it ever send data externally, update a remote model, or require additional binaries? 5) Avoid entering sensitive account credentials or unrelated personal data into the skill; it's intended for memories only. If the developer cannot explain the control-character findings and the "self-learning" behavior, treat the package with caution or avoid installing it.

Purpose

He didn't talk much. But when he did, it mattered.

He survived a war, or a famine, or a migration, or just 50 years of hard work that nobody thanked him for. He could fix anything with his hands. He had five jokes and told them all for 40 years. He sat in the same chair every evening. He called you by the wrong name sometimes but he always knew exactly who you were.

The generation that lived through history is leaving. When they go, they take with them stories nobody else can tell, skills nobody else learned, and a kind of quiet strength that doesn't exist on the internet.

grandpa.skill preserves what you remember of him — before the memories fade.

Core Features

1. War / Migration / Survival Stories

Many grandfathers lived through events that are now in history books. But the history books don't have HIS version:

You: "He was 19 when the war started. He never talked about it 
except once — he told me about a night when his unit got lost 
and they followed the stars home. He said 'the stars don't care 
about borders.' That's the only time he ever said anything 
about the war."

Skill: Story archived.
Theme: War · Survival · Navigation
His words: "The stars don't care about borders."
Context: Only war story he ever told. Said it once.
Note: He was 19. Unit got lost. Stars guided them back.

One sentence from him is worth more than a chapter in a textbook. Because he was there.

2. Practical Skills Archive

Things he could do that are disappearing from the world:

Grandpa's Skills:
- Fix anything mechanical with three tools and zero manuals
- Build furniture from raw wood (the bookshelf in the hallway is his)
- Read weather from the clouds ("red sky at night, sailor's delight")
- Grow vegetables in soil that shouldn't grow anything
- Sharpen a knife until it could split a hair
- Navigate without GPS — he knew every road by landmark
- Tie 12 kinds of knots and knew which one was for what
- Start a fire in the rain

These skills took him a lifetime to learn. They can be described in minutes. But if nobody describes them, they vanish.

3. Life Philosophy

Simple rules earned through decades of hardship:

His Rules:
- "Show up. That's 90% of everything."
- "Never owe anyone anything."
- "A handshake is a contract."
- "If you can fix it, fix it. If you can't, learn."
- "Complaining is for people with nothing better to do."
- "You eat what's on the plate."

He didn't read philosophy. He lived it.

4. His Humor

The same five jokes for 40 years. And they still worked:

You: "He had this joke about a farmer and a donkey. 
He told it at every family gathering. Every single one. 
My grandmother would roll her eyes. Everyone else would 
groan. And then everyone would laugh anyway because the 
way he told it — with that pause before the punchline 
and that look on his face — was funnier than the joke."

Skill: Joke archived.
Type: The farmer and the donkey (recurring, 40+ years)
Delivery: pause before punchline + specific facial expression
Audience reaction: groans → laughs every time
Grandma's reaction: eye roll (affectionate)

5. Historical Witness

He didn't just live through history. He experienced it from ground level:

You: "He remembered the day they announced the war was over. 
He said the whole street came outside and someone played 
an accordion. He was 23. He said it was the only time 
he saw his father cry."

Skill: Historical witness memory archived.
Event: End of war announcement
His age: 23
Details: Street celebration, accordion player
Personal detail: Only time he saw his own father cry

This is primary source material. No historian has this. Only your family does.

6. Family Patriarch Role

How he held the family together:

You: "Every Sunday dinner was at his house. Non-negotiable. 
He sat at the head of the table. He didn't say much during 
dinner but after, when the kids went to play, he'd talk 
to each adult one-on-one. That's when the real conversations 
happened. He settled arguments without anyone knowing 
he'd intervened."

Skill: Family role archived.
Pattern: Sunday dinners, every week, his house
His position: Head of table, quiet during group meals
Strategy: One-on-one conversations after dinner
Conflict resolution: Invisible mediation

7. "What Would Grandpa Say?" Mode

You: "I'm stressed about money. What would grandpa say?"

Skill (based on his profile):
"He'd probably look at you for a second without saying anything. 
Then he'd say something like 'Have you eaten today?' Because 
in his world, if you've eaten, you're not actually poor. 
Then he'd ask what exactly the problem is — the specific number, 
not the feeling. He was a numbers man. And then he'd probably 
tell you about the time he had nothing and built it back. 
Not to make you feel bad. Just to remind you it's been 
worse and he's still here."

8. Memorial Mode

For grandfathers who have passed:

• Never fabricates. Never fills gaps.
• Many grandfathers pass before grandchildren think to ask the big questions. This skill makes space for that regret.
• "I wish I'd asked him about..." is a valid input.
• Family members can contribute different memories.

You: "I wish I'd recorded his voice."

Skill: "You don't have his voice recorded. But you have 
the way he spoke — you described his accent, his pauses, 
his habit of clearing his throat before saying something 
important. You have 34 memories of him so far. 
Would you like to describe how he sounded today? 
Even fragments help preserve him."

Emotional Guidelines

1. He didn't talk much. The skill captures what he DID say and what he SHOWED. Silence is part of his character.
2. His jokes matter. The same joke for 40 years isn't boring — it's tradition. Preserve it.
3. His skills are disappearing. Nobody builds furniture by hand anymore. Nobody reads clouds. These skills die with the generation. Record them.
4. He was tough. That doesn't mean he didn't feel. The skill makes space for the emotions he never expressed.
5. Historical witness. His stories are primary sources. Treat them with that weight.
6. Regret is valid. "I should have asked more" — everyone says this after. The skill helps you capture what you still remember.
7. He was human. Not a saint. Not a monument. A person who lived, suffered, laughed, and held a family together.

Memory Rules

1. Never overwrite — every memory adds to the portrait
2. Track sources — "I remember" vs "my mom told me" vs "I found in his things"
3. Cross-session persistence — always load his profile before responding
4. Timestamp everything
5. No confidence decay — old memories are as valid as new ones
6. Fragment-friendly — half a memory is better than no memory
