What it does

Sdd Review is an agent skill from magnus919/hermes-profiles. SDD phase-gate review — enforces the SDD pipeline's gated structure by reviewing specification artifacts before the next phase can proceed. Produces artifact-pyramid-compliant gate decision reports. No phase passes without reviewed, approved artifacts.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/acceptance-review-patterns.md`, `references/implementation-review-patterns.md` and `references/phase-gate-methodology.md`).

The repository describes itself as: Curated Hermes Agent profiles for specialist swarms — opinionated, Hermes-optimized, artifact-pyramid native. The licence is MIT.

When your agent uses it

  • Tasks that involve Human-in-the-loop approvals

Example prompts

  • “/sdd-review”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Document the disagreement clearly — what the artifact says, what the reviewer found, why the author disagrees
  2. Escalate to the orchestrator or human if the finding is BLOCKING or CRITICAL
  3. MINOR and INFO disagreements are resolved by the reviewer's determination — the gate is not delayed for editorial preferences

What it can do on your machine

Read from SKILL.md and the folder at commit 867a555. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sdd Review loads about 1.8k tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 801 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SDD Phase-Gate Review

Enforcing the SDD pipeline's gated structure: every artifact is reviewed before the next phase proceeds. This skill owns the Review gates between every pair of SDD phases.

SDD Pipeline Position

[SPECIFY] → REVIEW → [PLAN] → REVIEW → [TASKS] → REVIEW → [IMPLEMENT] → REVIEW → [VERIFY]
     ↑         ↑        ↑        ↑         ↑         ↑           ↑          ↑
     └─────────┘        └────────┘         └─────────┘           └──────────┘
   Gate 1: Spec      Gate 2: Plan      Gate 3: Tasks          Gate 4: Implementation

Every gate asks the same question: "Is the artifact for this phase complete, correct, and unambiguous enough for the next phase to proceed safely?"

Core Principle: The Gate Is the Quality Mechanism

In SDD, quality is not enforced by code review — that's too late. Quality is enforced by the phase gate. A defect caught at Gate 1 (spec review) costs minutes to fix. The same defect caught at Gate 4 (implementation review) costs hours — the implementation may need to be discarded and rewritten against a corrected spec.

This skill is deliberately strict. Its job is not to be agreeable; its job is to protect downstream phases from upstream artifacts that would waste their time.

Artifact-Pyramid Output: REVIEW.md

Phase-gate review reports follow the artifact-pyramid structure:

LayerContentFile
L1Gate decision — APPROVED / CONDITIONS / REJECTED, one-line rationale, blocking findings count00-index.md (entry point)
L2Review findings by category — spec completeness, task correctness, implementation compliance, verification gapsIndividual *.findings.md files
L3Per-finding dossiers — severity, location (artifact + section), recommendation, evidence, escalation pathdossiers/ directory
SOURCESCross-reference from each finding to the artifact section it evaluatesFooter of each file

Trigger Conditions

Invoke this skill when:

  • A SPEC.md has been authored and needs review before work decomposition begins (Gate 1)
  • A TASK-PLAN.md has been produced and needs review before implementation starts (Gate 2)
  • Implementation output needs spec-compliance review (Gate 3)
  • A VERIFICATION.md report needs review before the pipeline delivers (Gate 4)
  • An escalation has been raised about an earlier gate decision and needs re-review

The Four Gates

Gate 1: Spec Review

Reviews SPEC.md against the quality gates defined in sdd-authoring. Questions asked:

  • Is every acceptance criterion testable?
  • Are edge cases enumerated, not just implied?
  • Are non-functional requirements specified with measurable thresholds?
  • Is the scope boundary clear (explicit in-scope and out-of-scope)?
  • Are data contracts and interface definitions sufficiently precise?
  • Does any section leave room for the implementation agent to make an unguided assumption?

Verdict: APPROVED only if every question produces a clear "yes" or has an explicit remediation plan.

Gate 2: Plan Review

Reviews TASK-PLAN.md against the specification. Questions asked:

  • Does every specification requirement map to at least one task?
  • Are dependencies real and spec-derived, not invented?
  • Is each task independently verifiable?
  • Are task sizes appropriate for a single implementation session?
  • Does the CLAUDE.md / AGENTS.md handoff accurately represent the spec and plan?

Verdict: APPROVED only if spec traceability is complete and dependency mapping is honest.

Gate 3: Implementation Review

Reviews implementation output against the task plan. This is NOT a general code review — it does not assess code style, test coverage, or architectural elegance. It asks only:

  • Does the implementation satisfy the acceptance criteria for each completed task?
  • Are there any deviations from the spec that were not documented?
  • Does the implementation produce correct results for all specified inputs?
  • Are error states handled per the spec?

Verdict: APPROVED only if all completed task ACs are satisfied.

Gate 4: Acceptance Review

Reviews the VERIFICATION.md report. Questions asked:

  • Are all spec ACs accounted for in the verification matrix (none missing)?
  • Are FAIL verdicts correctly classified by severity?
  • Are BLOCKING and CRITICAL failures accompanied by remediation plans?
  • Is the overall compliance score sufficient for delivery?

Verdict: APPROVED only if no BLOCKING failures exist and all CRITICAL failures have documented exceptions or remediation plans.

Gate Decision Format

Every gate produces one of three verdicts:

VerdictMeaningWhat happens next
APPROVEDArtifact passes all criteria. The next phase may proceed.Deliver artifact to next phase
CONDITIONSArtifact passes subject to specific remediations that do not require a full re-reviewDeliver artifact + conditions list; next phase may proceed while conditions are resolved
REJECTEDArtifact fails one or more criteria. The current phase must produce a revised artifact.Return artifact to current phase; no downstream work starts

Escalation

When a reviewer and artifact author disagree on a finding, the escalation path is:

  1. Document the disagreement clearly — what the artifact says, what the reviewer found, why the author disagrees
  2. Escalate to the orchestrator or human if the finding is BLOCKING or CRITICAL
  3. MINOR and INFO disagreements are resolved by the reviewer's determination — the gate is not delayed for editorial preferences
