Conciseness

Lean and dense: the four-lenses table delivers research findings Claude does not know ("Construction energy exceeds total query energy across 300 queries", "It is all KV cache in HBM"), the workflow block is bare commands, and nothing teaches known concepts. The three sentences of framing ("a memory engineer optimizes what it forgets") define the skill's core principle rather than pad. Every token earns its place.

Actionability

Fully executable: the five-step bash block is copy-paste ready and every flag was verified against the scripts' argparse (--print-sample-spec, --spec, --constraints, --dir, --policy, plus --output json and --sample as claimed). Exit-code interpretation per script is given ("0 · 2 finding · 3 bad input", "0 PASS · 2 CONDITIONAL · 4 FAIL"), and input provenance is covered (step 1 generates workload.json; the fillable forgetting_policy_template covers F1–F8).

Workflow Clarity

Clear 5-step sequence with explicit validation and feedback loops: "if construction dominates, cut construction tokens *before* touching retrieval", "on a tie it asks, exit 2", "Exit 4 is a stop, not a suggestion", a conditional skip ("skip if greenfield"), and a prove-by-hand-before-scheduling rule for step 5. Error semantics are defined by hard rule 6 ("A non-zero exit is a result to surface, not an error to swallow"). Not 4: checkpoints and error paths are explicit, not implicit.

Progressive Disclosure

Scored against the actual bundle: all 4 references, 3 assets, and 4 scripts referenced in the body exist on disk, and references are one level deep — the body keeps only findings and exit codes while sources and section detail ("§7", "(7 sources)") live in the referenced files. Each reference gets a one-line scope description, and the "References and assets" section plus scripts table make navigation trivial.

Specificity

Multiple concrete actions in third person: "Prices the write path, picks which cost to pay, classifies records as facts / skills / logs, and refuses a design that has no forgetting policy", plus "auditing what a CLAUDE.md or memory directory actually holds" and "choosing between long-context / RAG / graph / agentic memory" — coverage maps to every script plus the gate. Not 4: no coverage gaps; the action set is comprehensive for the skill.

Completeness

Explicitly answers both: 'what' via "Prices the write path, picks which cost to pay, classifies records as facts / skills / logs, and refuses a design that has no forgetting policy" and 'when' via "Use when designing, reviewing, or paying for an agent memory system" with concrete trigger phrases (adding memory, choosing architectures, auditing, deciding what to expire).

Trigger Term Quality

Good natural phrases users would say: "adding memory to an agent", "long-context / RAG / graph / agentic memory", "memory store keeps growing", "what to keep and what to expire", with synonyms (memory system / store / directory). Not 5: a few common natural terms are missing (e.g., "context window", "vector store/database", "knowledge base"); not 3: coverage goes well beyond the 'some relevant keywords' anchor.

Distinctiveness Conflict Risk

Clear niche — engineering an agent memory system with a forgetting gate — with distinct decision-context triggers ("choosing between long-context / RAG / graph / agentic memory", "deciding what to keep and what to expire"). Only minimal overlap risk (the CLAUDE.md audit mention brushes an init-type skill, but the auditing frame is distinct).
