testland/restore-time-tests

Build restore-time SLA tests - per-database + per-object-store baseline measurement, RTO objective verification, parallel-restore optimization tests, point-in-time-recovery (PITR) latency. Bound `time-to-functional` (TTF) ≤ documented RTO; flag silent regressions when restore time grows over months. Use when a service documents an RTO nobody has actually timed, when the backup has grown by an order of magnitude, or right after a backup-tool change.

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, lean, code-heavy skill with a clear sequenced workflow, pervasive timing-budget validation, and a useful anti-patterns/limitations framing. Its main gap is that several executable examples depend on undefined helper stubs, keeping the code from being fully copy-paste ready.

Suggestions

Define the helper functions used in the examples (run_restore, restore_retained_base_backup, write_conf, wait_for_recovery_complete, sample_500_keys_from_inventory, run_smoke_suite, do_restore) or explicitly flag them as placeholders, so the test code is copy-paste executable rather than relying on inferred stubs.

Replace the 'VersionId: ...' placeholder in the S3 partial-restore example with a concrete version-id lookup so test_partial_object_restore_under_5_min is runnable as written.

Add an explicit validate→fix→retry note around the destructive DROP DATABASE/CREATE DATABASE setup (e.g., assert the clean target exists before starting the timer) so the feedback loop is visible in the workflow itself, not only via CI gating.

DimensionReasoningScore

Conciseness

The body is lean and code-first, assuming Claude's competence; prose adds only non-obvious guardrails (per-segment budget choice, the do-NOT-call-pg_basebackup-at-restore-time footgun, illustrative-vs-real values) rather than explaining concepts Claude already knows.

3 / 3

Actionability

The core postgres restore test, pg_restore/pgbackrest commands, and metrics emission are concrete and runnable, but several tests call undefined helpers (run_restore, restore_retained_base_backup, write_conf, wait_for_recovery_complete, sample_500_keys_from_inventory) and the S3 example leaves VersionId as '...', so the code is not fully copy-paste executable as written.

2 / 3

Workflow Clarity

A clearly sequenced 8-step process where each timing assert acts as an explicit validation gate, Step 7 is dedicated verification, and the Anti-patterns table serves as a recovery checklist — satisfying the clear-sequence-with-validation anchor rather than the validation-gap level 2.

3 / 3

Progressive Disclosure

Single well-organized file with clearly signaled one-level references (## References section, inline link definitions for external docs and sibling skills) and no nested reference chains; keeping the test templates inline is appropriate for this skill type.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that pairs concrete restore-time SLA testing actions with natural 'Use when' triggers and a clearly bounded DR-readiness niche. It avoids vague fluff and over-claims, and uses third-person voice throughout.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'per-database + per-object-store baseline measurement', 'RTO objective verification', 'parallel-restore optimization tests', 'PITR latency', 'Bound time-to-functional (TTF) ≤ documented RTO', 'flag silent regressions' — matching the multiple-specific-actions anchor.

3 / 3

Completeness

Explicitly answers both what (build restore-time SLA tests, measure baselines, verify RTO) and when via a dedicated 'Use when...' clause with concrete triggers, so it is not the missing-when level 2.

3 / 3

Trigger Term Quality

The 'Use when' clause surfaces natural triggers a user would actually say ('a service documents an RTO nobody has actually timed', 'the backup has grown by an order of magnitude', 'right after a backup-tool change') plus RTO/restore/backup/PITR terms, giving good coverage rather than just jargon.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear restore-time/DR-readiness niche with distinct triggers unlikely to fire for generic backup skills, and its adjacent sibling skills (dr-drill-runner, backup-verification-author) are explicitly separate concerns.
