An automated backup workflow for Cognithor configuration files, skill definitions, and data directories. It creates timestamped compressed archives on an hourly cron schedule, a system scheduler for recurring commands.

Use it to create scheduled Cognithor backups, verify archive integrity, retain recent hourly snapshots, and report backup or storage failures.

It provides restorable snapshots and checks that each archive can be read. It also removes older snapshots beyond the configured retention window and reports problems such as a full disk.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Tool Misuse · line 30
Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.

Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.

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 5.1	$0.00051	$0.00484
Opus 5.5	$0.00020	$0.00194
Sonnet 5.5	$0.00010	$0.00097
Haiku 4.5	$0.00005	$0.00048

Security

Grade A, and why

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 2mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (__init__.py, skill.py, test_skill.py), 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

Backup

Automated backup skill that creates timestamped archives of Cognithor configuration, skills, and data on a cron schedule (0 * * * * — hourly by default).

Steps

Check prerequisites — verify backup target exists and has write access:

BACKUP_DIR="${COGNITHOR_HOME:-$HOME/.cognithor}/backups"
mkdir -p "$BACKUP_DIR" && test -w "$BACKUP_DIR"

Create timestamped archive of config, skills, and data:

STAMP=$(date +%Y%m%d_%H%M%S)
tar czf "$BACKUP_DIR/cognithor_$STAMP.tar.gz" \
  -C "${COGNITHOR_HOME:-$HOME/.cognithor}" \
  config/ skills/ data/

Validate integrity — verify the archive is readable:

tar tzf "$BACKUP_DIR/cognithor_$STAMP.tar.gz" > /dev/null

Prune old backups — keep the last 24 hourly snapshots:

ls -1t "$BACKUP_DIR"/cognithor_*.tar.gz | tail -n +25 | xargs rm -f

Return status — the skill returns {"status": "ok", "automated": true} on success

Example

User > Starte ein Backup meiner Cognithor-Daten
Cognithor > Backup erstellt: cognithor_20260420_140000.tar.gz (12 MB)
         Nächstes automatisches Backup: 15:00 Uhr

Error Handling

Disk full: Log warning, skip archive creation, alert user to free space
Permission denied: Verify $BACKUP_DIR ownership and retry with correct permissions
Corrupt archive: Re-run backup immediately; if persistent, check filesystem health

Files

What ships with it

4 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.
