Lists multiple specific concrete actions: catching surviving placeholder text, unswapped template imagery, layout overflow, hidden-original leaks. These are precise, actionable QA checks rather than vague language.

Clearly answers both 'what' (catches placeholder text, unswapped imagery, layout overflow, hidden-original leaks) and 'when' (end of deck-creation flow at Step 9/QA, or when user asks 'is this deck ready?'). Also includes explicit negative triggers for when NOT to use it.

Includes natural trigger phrases users would say ('is this deck ready?', 'QA my deck') and technical triggers ('Step 9 / QA'). Also specifies when NOT to trigger, which helps with precision. Terms like 'Google Slides', 'deck', 'QA' are natural user language.

Highly distinctive — scoped specifically to QA of Google Slides decks created by the same agent in the current session, with explicit exclusion of externally-created decks. The dependency on a Step 5 pre-fill snapshot and the specific failure modes make it very unlikely to conflict with other skills.

The skill is fairly long but most content earns its place — the sub-agent prompts are necessarily detailed and specific. However, there's some redundancy (e.g., the bias explanation is repeated in both the intro and workflow step 5, and some phrasing could be tightened). The opening paragraph explaining *why* the skill exists is useful context but slightly verbose.

Extremely actionable: provides literal copy-paste sub-agent prompts with specific tool calls, exact YAML output schemas, concrete template-token lists to scan for, specific severity categories, and a fully worked example of the aggregated report format. Every step names the exact API call to use.

The workflow is clearly sequenced with explicit validation at multiple levels: input sanity-checking before spawning sub-agents, required `inspected_slide_ids`/`compared_slide_ids` audit trails to prevent silent skips, a fix-then-rerun loop with an iteration cap at 3, and clear escalation to the user when the loop fails. The feedback loop contract is explicit and well-bounded.

The skill references `../google-slides/references/workflow.md` for the snapshot schema, which is good progressive disclosure. However, the skill itself is quite long (~250 lines) with the three full sub-agent prompts inline. These prompts could potentially be split into separate reference files to keep the main SKILL.md as a concise overview, though there's an argument for keeping them inline since they're the core deliverable. No bundle files are provided to verify the referenced path exists.
