What is upgrade-where-backup?

A procedure for upgrading an old backup from the Where app to a newer format and checking that its contents remain usable.

Use it to upgrade, migrate, repair, validate, or test-import a legacy Where backup directory or ZIP file.

It reduces the risk of losing records or damaged files during a backup migration. It also verifies that the upgraded backup can be opened by Where's backup service.

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.

Model	Per session	Once invoked
Fable 5	$0.00067	$0.00491
Opus 5	$0.00034	$0.00246
Sonnet 5	$0.00013	$0.00098
Haiku 4.5	$0.00007	$0.00049

Security

Grade A, and why

upgrade-where-backup 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/upgrade_and_verify.rb), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Upgrade a Where backup

Read the root AGENTS.md, Where/AGENTS.md, and Where/WhereCore/AGENTS.md. Load the running-tests skill. Verification must run through ./test.

Run the bundled driver from the repository root:

ruby .agents/skills/upgrade-where-backup/scripts/upgrade_and_verify.rb INPUT [OUTPUT]

INPUT may be an unpacked backup directory or ZIP. OUTPUT defaults to a sibling named <input>-upgraded.zip. The driver:

Reads the source manifest and records the counts that migration must preserve.
Creates a temporary input ZIP when necessary.
Runs the repository's pinned Ruby and Where/Tools/upgrade-backup.rb.
Checks ZIP integrity, the current manifest version, required tables, and counts.
Writes the backup path and expected counts to a temporary JSON configuration.
Enables and runs BackupServiceTests.upgradedBackupDecodesAndLoadsAssets through ./test, exercising BackupService.readArchive(at:) and all referenced asset bytes. The test is compiled but disabled during normal runs.

Keep every manifest transformation in Where/Tools/upgrade-backup.rb. The driver only packages input, invokes that authority, and independently verifies its output. Do not duplicate migration rules in the skill.

Safety and recovery

Never modify or delete the input.
Do not pass --force unless the user explicitly approves replacing the exact output path. Without it, an existing output is rejected.
Expect filesystem approval when the output is outside the workspace.
The upgraded ZIP remains available if Swift verification fails. Diagnose the failure. Do not represent the backup as verified.

Handoff

Report the output path, source and destination format versions, preserved record counts, ZIP result, Ruby regression result, Swift production-decoder result, and whether the repository is clean. Do not expose backup contents in logs or the response.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

upgrade-where-backup is a skill published in the GitHub repository kyleve/Stuff (3 stars, last pushed today), licensed Apache-2.0. It adds 67 tokens to every session and 491 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
