Conciseness

The body is compact and adds only novel information (the interceptor system, built-in names, RPC endpoints) that Claude could not already know, but the intentionality point is restated three times ('They are not bugs in the tool', 'that is not a failure', 'This is intentional; do not reverse it') — minor over-explanation that could be trimmed to one statement. Anchor 5 requires every token to earn its place with no such repetition.

Actionability

Concrete, actionable guidance throughout: a literal directive example with tool and args, named tools (memory_search, deep_recall, memory_status), the guards.status RPC, and explicit follow instructions ('run the named tool first, then re-evaluate'). Minor gaps remain, e.g., what to do when the prerequisite call returns nothing or the directive names an unknown tool, so it falls short of the fully-covering anchor 5.

Workflow Clarity

The core workflow is clearly sequenced — recognize the INTERCEPTOR: prefix, run the named prerequisite tool, re-evaluate the original action, proceed without commentary — and the skill is non-destructive so no validation cap applies. The re-evaluation step lacks an explicit decision checkpoint for when the original action no longer applies, keeping it below anchor 5.

Progressive Disclosure

The skill is under 50 lines with no need for external references, and its content is organized into clear, well-ordered sections (Reading a directive, Built-in interceptors, Observability) with no inlined material that belongs in separate files. Per the simple-skill guideline, this matches the top anchor.

Specificity

The description names the domain with concrete, recognizable signals ("tool error begins with 'INTERCEPTOR:'", "silently hedged or rewritten", "active guards", "blocked actions") but lists no capability actions. It sits above anchor 2 (generic domain-only) yet below anchor 4, which requires several specific actions to be enumerated.

Completeness

The 'when' is explicit and multi-triggered, but the 'what' is entirely absent — the description never states what the skill actually does (e.g., explaining or handling the interceptor system). This matches anchor 2 ('only when is present without what') and cannot reach anchor 3, which requires a clear 'what'.

Trigger Term Quality

Triggers include the exact-match token 'INTERCEPTOR:' plus natural phrases like 'active guards', 'blocked actions', and 'hedged or rewritten' that a user or operator would plausibly echo. Coverage is good but missing common synonyms or variations (e.g., 'guardrail', 'tool blocked', 'message changed'), keeping it below anchor 5.

Distinctiveness Conflict Risk

The 'INTERCEPTOR:' error prefix is a unique, unmistakable trigger, and the explicit exclusion 'Not for ordinary tool errors' fences off the nearest overlapping domain. Clear niche with minimal conflict risk, matching anchor 5.
