foundation: Skill for Claude Code

.agents/skills/backup-vault/SKILL.md

backup-vault is a skill for Claude Code, Codex from dgraziosi/foundation. It costs 47 tokens per session (526 once invoked), scanned A, original, MIT.

A check for the nightly backup dump of the vault, which is the running local instance and its stored data. The dump is created by a host script, while this routine checks whether it exists and is recent.

In plain words
What is it for?
Use it to check for a missing or older-than-48-hours backup and to run the backup script when the user asks for a dump.
Why use it?
It alerts the user when a recent copy may be missing, without confusing backup checks with service health checks.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is dgraziosi/foundation's own configuration. It tells Claude Code and Codex how to work on foundation itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything foundation configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/backup-vault.sh.

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

backup-vault 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.

What it actually says

Backup vault

You are checking the nightly vault backup. The user can run this, or attach it to Vault Keeper.

Read docs/BACKUP.md. The dump itself is the host script scripts/backup-vault.sh on this machine’s schedule, not a bot wake. Do not rewrite the script.

The user is the human who runs this vault on this machine. A vault is this running instance (FOUNDATION_DATA + Postgres). Do not call the graph “the Vault.” Dumps stay out of git.

Schedule and voice

Nightly, local time. The host script dumps. Ping the user if the dump is missing or old. Health checks the backup path; it does not dump.

User config

Driven by env, else the clone .env (same as keep-up). Relative paths are under the clone.

  • FOUNDATION_DATA — the vault (default ./data under the clone)
  • BACKUP_ROOT — optional. Also read from the clone .env. Default: sibling of the data dir
  • BACKUP_AGE_RECIPIENT — required for dump
  • BACKUP_AGE_IDENTITY — required for restore
  • BACKUP_KEEP_DAYS — optional. Default 14
  • BACKUP_OFFSITE — optional. A folder on this machine that the user copies or syncs

Steps

If the user asked to dump now, from the clone, with Postgres up:

set -a && source .env && set +a
./scripts/backup-vault.sh

Otherwise nag if the dump is missing or older than 48 hours. Newest artifact may be foundation-YYYYMMDD.sql.age.

Throwaway restore for practice: docs/BACKUP.md. In-place restore on this vault: scripts/restore-vault.sh with --in-place --confirm YYYYMMDD. That script stops this vault's app, then loads the dump. A leftover $FOUNDATION_DATA/.restore-failed means restore did not finish; keep-up will not start until you run restore again. Do not invent another machine.

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.
