esdd

Express Spec-Driven Development for project setup, domain documentation, planning, implementation, revision, verification and archiving. Use only when the user asks for ESDD, references an ESDD command or artifact, or follows up on an existing ESDD change.

Quality

Content

96%Weight 40%Scale 1-5

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

An exemplary dispatcher body: lean, fully executable, and sequenced with explicit gates and verification requirements, with references correctly organized one level deep. The only weakness is that the docs.*.md deep-dive files in references/ are not reachable from any navigation path in the skill.

Suggestions

Link the four docs.*.md files from the relevant action references (e.g. have apply.md/continue.md point to docs.artifacts.md and docs.workflows.md) or from SKILL.md's Working Rules, so their substantial content is discoverable rather than orphaned.

DimensionReasoningScore

Conciseness

The ~45-line body is a lean dispatcher: no concept explanations, no padding, and dense imperative rules ("Treat the first word as $ACTION, remainder as $REST"; "Discussion and review do not authorize edits") that assume Claude's competence. Every token earns its place — this matches the anchor-5 'lean and efficient' profile.

5 / 5

Actionability

Every instruction is executable: exact CLI commands are given ("node <skill-dir>/scripts/cli.mjs init --status", "list", "status \"<name>\" --apply"), input parsing is precisely defined, and all ten action references link to real files in references/. Although it is an instruction-only skill, the guidance is fully concrete with copy-paste-ready commands, satisfying the anchor-5 bar via the code_vs_instruction note.

5 / 5

Workflow Clarity

A clear 6-step sequence is backed by explicit validation checkpoints: the Init Gate validates state with both failure branches defined, change selection handles ambiguity ("ask if several are plausible") and stop conditions, and the Working Rules mandate verification ("Check tasks only when implementation and relevant verification satisfy their outcomes", "Run relevant tests and build/type checks after code corrections") with the revision reference as the fix-then-proceed loop. The destructive/batch cap does not apply since verification steps are present.

5 / 5

Progressive Disclosure

The body is a model overview: ~45 lines that dispatch to ten clearly-signaled one-level-deep action references, all verified to exist, with shared-* files linked from the action references. Not 5 because four substantial bundle files (docs.artifacts.md, docs.commands.md, docs.configuration.md, docs.workflows.md) are orphaned — no link in SKILL.md, any action reference, help.md, or the scripts reaches them — a minor navigation/discovery gap against the 'easy navigation' anchor.

Description

80%Weight 40%Scale 1-5

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 description with an explicit, well-gated when-clause and clear niche identity. The main weakness is trigger breadth: it relies solely on the literal token "ESDD", so a user asking for "spec-driven development" or a spec-change follow-up without naming ESDD may not match.

Suggestions

Add natural synonyms to the trigger clause, e.g. "Use only when the user asks for ESDD or spec-driven development, references an ESDD command or artifact (e.g. a change spec), or follows up on an existing change made with this skill."

Name the concrete artifacts the skill manages (change specs, domain specs, workflow config) in the what-clause so artifact references in conversation can match even when the word ESDD is absent.

Mention the exploration/review capability (e.g. "project setup, domain documentation, change planning and review, implementation, verification and archiving") to close the coverage gap.

DimensionReasoningScore

Specificity

"Express Spec-Driven Development for project setup, domain documentation, planning, implementation, revision, verification and archiving" lists seven named lifecycle activities — several specific actions covering the full init-to-archive span. Not 5 because these are lifecycle phase labels rather than fully concrete operations, and coverage has a minor gap (the explore and view actions are unmentioned).

4 / 5

Completeness

Both questions are explicitly answered: the what names the methodology and its seven concrete phases, and "Use only when the user asks for ESDD, references an ESDD command or artifact, or follows up on an existing ESDD change" is an explicit when-clause with concrete trigger phrases, matching the anchor-5 example pattern.

5 / 5

Trigger Term Quality

The when-clause offers several trigger categories ("asks for ESDD", "references an ESDD command or artifact", "follows up on an existing ESDD change") but every keyword is the single term ESDD; common variations like "spec-driven development" or "plan/verify a spec change" appear in the what-clause but not as triggers. This sits between anchor 3 (relevant keywords, missing variations) and anchor 4, closer to 3 because no synonyms are present.

3 / 5

Distinctiveness Conflict Risk

The restrictive "Use only when the user asks for ESDD..." trigger gives the skill a clear niche and makes accidental triggering by generic requests (planning, verification) essentially impossible — minimal conflict risk, matching the anchor-5 example's structure.
