What it does

Hax Ubd Six Facets is an agent skill from haxtheweb/haxcms-php. Apply the UbD six facets of understanding (Explanation, Interpretation, Application, Perspective, Empathy, Self-Knowledge) to write understandings and build facet-mapped editable-table rubric criteria. Use when the user says "what facet does this target", "build a rubric for understanding", or "which facets should this assessment tap". Companion to hax-ubd-stage2; bridges to grad-blooms (facets = performance criteria; Bloom's = cognitive level).

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Education, covering Quizzes and assessments. The repository describes itself as: HAX + CMS to manage your microsite universe with PHP backend. The licence is MIT.

When your agent uses it

  • The user says what facet does this target
  • Build a rubric for understanding
  • Which facets should this assessment tap

Example prompts

  • “what facet does this target”
  • “build a rubric for understanding”
  • “which facets should this assessment tap”
  • “/hax-ubd-six-facets”

What it can do on your machine

Read from SKILL.md and the folder at commit 3542096. 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

Hax Ubd Six Facets loads about 1.7k tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 645 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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.

HAX UbD Six Facets of Understanding

Use the six facets as a lens for writing understandings and a blueprint for rubric criteria. This is the focused companion to hax-ubd-stage2. The facets are criteria for judging understanding, not learning styles — they describe what teachers need to see to conclude a student understands.

The six facets (UbD Ch. 4)

FacetDefinitionKey verbs"A student who really understands…"
ExplanationSophisticated, justified accountsexplain, justify, verify, prove, generalize, predictshows their work; gives good reasons; connects facts into a theory
InterpretationMeaningful narratives/translationsinterpret, make meaning, tell significance, translatefinds significance; tells a powerful story; makes the unfamiliar accessible
ApplicationEffective use in new contextsapply, transfer, adapt, customizeuses knowledge wisely in diverse, "noisy" situations; has tact
PerspectiveCritical points of viewcritique, compare, question assumptions, see the big picturesees from multiple vantage points; exposes questionable assumptions
EmpathyAnother's feelings/worldviewrole-play, relate, walk in another's shoesfinds what is plausible/meaningful in alien-seeming ideas; has a change of heart
Self-KnowledgeAwareness of one's own biases/limitsself-assess, reflect, know one's ignoranceknows what they don't understand; knows how their habits shape their thinking

When to Use

  • "What facet does this target" / "build a rubric for understanding"
  • "Which facets should this assessment tap" / "is my rubric measuring understanding or just correctness"
  • You are hax-ubd-stage2 building the rubric blueprint (step 4)

When NOT: cognitive level of a task → grad-blooms (the facets are performance criteria; Bloom's is the cognitive level — they compose, see below). Full evidence scrapbook → hax-ubd-stage2.

Methodology

  1. For each targeted understanding, ask: which facets, if performed well, would most strongly reveal this understanding? (Not all six apply to every understanding — e.g., Self-Knowledge/Empathy rarely apply to pure math concepts.)
  2. Draft rubric criteria per chosen facet using the facet's verbs. Each criterion should describe observable performance, not an internal state.
  3. Include ≥1 impact criterion (effect on audience / real-world consequence), not just correctness + craft. Over-weighted craft criteria are the classic validity failure (self-test Q4).
  4. Render the rubric as an editable-table (analytic-trait scoring) — one criterion row per facet tapped, columns = performance levels with anchor descriptions.
  5. Bridge to grad-blooms: confirm the cognitive level implied by each facet criterion matches the intended objective level (e.g., an Application facet criterion implies Apply or higher).

Output Format

# Six-Facet Rubric: {understanding}
## Facets tapped
{which facets, why — e.g., "Application + Explanation: this understanding is about using the concept and justifying the use"}
## Rubric (editable-table)
| Criterion (facet) | Level 4 (exemplar) | Level 3 | Level 2 | Level 1 |
| {criterion} (Application) | ... | ... | ... | ... |
| {criterion} (Explanation) | ... | ... | ... | ... |
| {impact criterion} | ... | ... | ... | ... |
## Bloom's bridge
{each criterion → implied cognitive level via grad-blooms; confirm match to objective}
## HAX handoff
{editable-table for rubric; per-facet evidence components}

Acceptance criteria

  • Each rubric criterion maps to a named facet.
  • ≥1 criterion is an impact criterion (audience/real-world effect), not just correctness/craft.
  • Criteria describe observable performance (verbs from the facet), not internal states.
  • Understanding/craft criteria are separate and weighted so a lovely product with shallow understanding cannot score high (guards self-test Q4).
  • Bloom's bridge: each criterion's implied cognitive level matches the intended objective (no Analyze-level criterion on a Remember-level objective, and vice versa).

Gotchas

  • Not all six facets apply everywhere. Self-Knowledge and Empathy rarely apply to pure math/conceptual understandings. Don't force a quota — pick the facets that genuinely reveal this understanding.
  • Facets are criteria, not styles. A student need not "have" a facet as a trait; the rubric looks for the performance regardless of preference (like an essay must be persuasive whether or not the writer is persuasive).
  • Don't confuse Explanation (Facet 1) with "Understand" (Bloom L2). Explanation is a performance criterion (justify/show work); Bloom's Understand is a cognitive level. The bridge step reconciles them.
  • Beware craft-over-understanding. A polished product with shallow thinking is the #1 validity trap. Keep understanding criteria distinct and dominant.
