Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00034 | $0.00398 |
| Opus 5.5 | $0.00014 | $0.00159 |
| Sonnet 5.5 | $0.00007 | $0.00080 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
rollback-probe 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 24d 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
Rollback Probe
Certifies database migration and schema reversibility via automated roundtrip execution.
When to Use This Skill
- An AI agent creates or edits database migrations (Liquibase, Flyway, Prisma, raw SQL).
- A CI gate needs to ensure that deployment rollbacks will not fail in production.
- A project enforces that every forward schema change has a verified inverse.
Path resolution
Resolve references/ and scripts/ relative to this skill's install directory (e.g. .agents/skills/rollback-probe/ or .claude/skills/rollback-probe/).
Workflow
- Read
references/rollback-contract.mdto review the 3-step roundtrip invariant. - Execute the rollback probe:
# Verify Liquibase/SQL rollback integrity
node scripts/rollback-probe.mjs \
--forward "npm run migrate:up" \
--rollback "npm run migrate:down"
# Run with optional verification assertion and JSON diagnostics
node scripts/rollback-probe.mjs \
--forward "npm run migrate:up" \
--rollback "npm run migrate:down" \
--verify "npm test -- tests/db.test.js" \
--json
- If the probe fails:
- Inspect the failed step (
2_ROLLBACKor3_REAPPLY_FORWARD). - Fix the inverse SQL /
<rollback>tag or restore dropped constraints. - Re-run until the probe exits with code 0.
- Inspect the failed step (
Done When
scripts/rollback-probe.mjsexits with code 0.- Forward $\rightarrow$ Rollback $\rightarrow$ Forward succeeds without errors.
What ships with it
3 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.
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.

rollback-probe is a skill published in the GitHub repository ALTEN-group/coding-pal (5 stars, last pushed 5d ago), licensed MIT. It adds 34 tokens to every session and 398 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-24.
