Conciseness

Most of the body is dense, non-obvious operational guidance that earns its tokens (model-selection heuristics, ledger recovery, fix-loop policy, the rationalizations table), and it assumes competence rather than explaining basics. But the two DOT digraphs (~75 lines) restate what the following prose sections (Setup, The Task Loop, Final Review, Finish) already specify — the process graph duplicates the per-task loop nearly statement-for-statement — which is a padded section that could be cut entirely. Fits anchor 3 ('mostly efficient but could be tightened') more than 4, which would require only 'minor instances' of trimmable material.

Actionability

Guidance is fully executable: exact script invocations ('bash scripts/sdd-workspace PLAN_FILE', 'bash scripts/review-package PLAN_FILE BASE HEAD'), a concrete BASE-recording rule with the HEAD~1 failure mode named, exact ledger line formats ('Task <N>: fix round <R>/5 (...)'), a four-value implementer status taxonomy with a handling rule per value, an enumerated dispatch contract (1)-(5), and a worked example workflow covering the common path including a fix round. Fits anchor 5 ('copy-paste ready commands; specific examples cover the common cases').

Workflow Clarity

The multi-step process is explicitly sequenced (Setup → task loop steps 1-5 → final review → finish) with validation checkpoints throughout: every task gates on a two-verdict review, fixes get scoped re-reviews with per-finding ADDRESSED/NOT ADDRESSED verdicts, a 5-round breaker with adjudication rules, and destructive operations (rm -rf workspace, git clean -fdx) are explicitly fenced behind a clean final review. Feedback loops, error recovery routes, and a rationalizations checklist are all present — anchor 5 exactly.

Progressive Disclosure

The structure is conceptually right: SKILL.md is the overview, per-role prompt templates are offloaded to separate files, and the three referenced scripts (scripts/sdd-workspace, scripts/task-brief, scripts/review-package) exist in the bundle. However, three of the most load-bearing referenced files — implementer-prompt.md, task-reviewer-prompt.md, and re-review-prompt.md — are absent from the bundle, so the disclosure chain is broken exactly where the skill delegates its detailed contracts. That drops it below anchor 4's 'minor organization gaps' to anchor 3's 'could be better organized' territory, though the references that do exist are clearly signaled and one level deep.

Specificity

The description names the domain ("executing implementation plans with independent tasks") but names zero concrete actions — nothing about dispatching subagents, per-task review, or final whole-branch review, all of which are the skill's actual work. It matches anchor 2 ('Names the domain but actions are minimal or generic', e.g. 'Processes PDF files') and is above anchor 1 only because the domain itself is specific rather than 'entirely vague'.

Completeness

Only the 'when' half is present ("Use when executing implementation plans with independent tasks in the current session"); the 'what' — what the skill actually does — is entirely absent. This is exactly anchor 2 ('only "when" is present without "what"'): the 'when' clause itself is clear, so it is not anchor 1, but a clear 'what' would be required for anchor 3+.

Trigger Term Quality

"executing implementation plans", "independent tasks", and "current session" are phrases a user might plausibly say, but common variations and synonyms are missing — nothing like "run the plan", "carry out the tasks", "execute this plan", or "subagent(s)", which is the skill's defining mechanism. Fits anchor 3 ('Some relevant keywords but missing common variations or synonyms'), not 4 (which needs the variations covered) or 2 (keywords are domain-relevant, not generic like 'works with files').

Distinctiveness Conflict Risk

The description is domain-specific (plan execution, not generic help), but it does not mention subagents — the feature that distinguishes this skill from the sibling inline 'executing-plans' skill it explicitly contrasts with in the body, so the same trigger could fire either skill. Fits anchor 3 ('Somewhat specific but could still overlap with similar skills'); anchor 4 would require the distinguishing mechanism to be visible in the description itself.
