| description | Refine a draft prompt before sending to a coding agent: decomposes goal/context/constraints, flags ambiguity, emits a model-agnostic rewrite. NOT for prompts from scratch (mk:brainstorming). |
mk:prompt-enhancer
Refine a draft user prompt using a 5-step framework — mode-select, decompose,
detect, (scout if --deep), map, rewrite — grounded in 7 source docs
(Anthropic / OpenAI Codex / FactoryAI prompting + Anthropic context-engineering
- skill-authoring rules). The rewrite uses the universal kernel only (the rule is Hard Constraints item 4).
When to use
- Draft prompt is ambiguous, missing context, weakly structured, or coupled to one model's framing (XML, role-as-XML, "think step by step", etc.).
- User says: "enhance prompt", "optimize prompt", "make this prompt better", "rewrite this prompt".
- Want to see WHY a prompt was rewritten: append
--analyze.
- Want a numeric quality score on the original prompt: append
--score (auto-promotes to --analyze --score).
- For codebase-aware suggestions: append
--deep (opt-in only).
- Explicit:
the prompt-enhancer skill [--analyze] [--score] [--deep] [--save-to <path>] [text].
- Architecture-review prompts: use the recipe in
references/architecture-review-mode.md via --analyze --deep — it rewrites the prompt to ASK for a review; it never performs one (that is mk:review). Recipe is opt-in via those flags; default-mode output is unchanged.
When NOT to use
- Generating a prompt from scratch →
mk:brainstorming (technical) / mk:office-hours (product).
- Re-examining a code review or plan →
mk:elicit.
- Building an implementation plan →
mk:plan-creator.
- Auditing running output of an LLM →
mk:evaluate or mk:review.
- General codebase scouting →
mk:scout directly.
Workflow
Mode-Select → Decompose → Detect → (Scout if --deep) → Map → Rewrite.
Mode selection + the arch-review / research recipes: references/mode-routing.md.
Step detail in references/decomposition-checklist.md, references/playbook.md,
references/context-safeguards.md, references/deep-mode-scout.md. Do not invent steps.
Inputs
- Required: a draft prompt (text). Empty / missing → refuse with redirect.
- Optional:
--analyze (include decomposition + detected issues + improvement suggestions).
- Optional:
--score (add 1–10 quality score on the original prompt; auto-promotes to --analyze --score because score requires the rubric components).
- Optional:
--deep (opt-in scout against allow-listed sources).
- Optional:
--save-to <path> (default: active plan dir if any, else ${PLUGIN_DATA}/...).
The skill does not accept a --model flag. Per the synthesis report
(tasks/reports/synthesis-260509-2058-prompting-framework.md), model
detection violates the model-agnostic mandate; dispatch by model-tier lives
in harness-rules.md Rule 5, not here.
Output
Mode-aware. See assets/output-template.md for the templates.
| Flags | Output |
|---|
| (none) — default | Section 4 only — the Enhanced Prompt code block |
--analyze | Sections 1, 2, 3, 4 (decomposition + issues + suggestions + rewrite) |
--analyze --score | Sections 1, 2, 3 + Score: N/10 block + Section 4 |
--score (alone) | Auto-promoted to --analyze --score |
--deep (any mode) | Appends "Suggested context" sub-block to Section 4 when scout returns ≥1 hit |
--analyze + explicit target named | Appends "Target-specific notes" block after Section 3 (annotation-only; rewrite unchanged). See references/target-notes.md |
Internal decomposition + detection still run in default mode (they feed the
rewrite) but are emitted only with --analyze. The rewrite's OUTPUT FORMAT line
always carries the auto-suggested Freedom level (LOW/MEDIUM/HIGH) and
Verbosity (terse/structured/confirmation) — see below.
References
references/mode-routing.md — mode-selection table (default / analyze / score / deep) + the arch-review and research recipes (links to architecture-review-mode.md).references/decomposition-checklist.md — 5 components + 10-item weakness checklist.references/playbook.md — improvement fixes, one per checklist item, with doc citation. Includes the deterministic Scoring Rubric used by --score.references/context-safeguards.md — 6 model-agnostic safeguards (right-altitude tone, identifier-based context, long-horizon defenses, tool-result clearing, bloat avoidance, eval discipline). Loaded JIT when input shows long-horizon signals or codebase-context references.references/deep-mode-scout.md — --deep allow-list, forbid-list, hard caps, fallback.references/complexity-classifier.md — content-shape lens (10 prompt types → strategy + output length + research framing). Loaded at Step 1; orthogonal to flag modes.references/task-recipes.md — per-type emphasis maps (coding / review / research / planning / long-context / migration / debugging / design / orchestration). Loaded at Step 3 when the classifier matches a non-trivial type. Reshape emphasis only — never performs the task.references/target-notes.md — optional model-specific steering notes. Renders ONLY in --analyze when the input explicitly names a target; annotation-only (never changes the rewrite); no --target flag; silent in default mode.
Hard Constraints (read every run)
Default mode (always):
- Preserve user intent verbatim. Never silently change the core ask.
- Never invent facts. Unknown values become
[FILL-IN: <description>] placeholders.
- No padding. Only emit suggestions for FOUND issues. (Default mode hides suggestions entirely;
--analyze reveals them.)
- Universal kernel only. Plain markdown sections (Goal / Context / Constraints / Acceptance Criteria / Output Format). No XML tags, no role-as-XML, no model overlays. If the input prompt contains model-coupled framing, flag it as detection #10 and strip during rewrite. Why: the rewrite must stay portable across coding agents (Codex, Codex, Gemini, Droid) — a vendor token optimizes for one and can degrade another. Model-specific tips surface only via
--analyze target-notes when the user names a target; they never enter the default rewrite.
- Default = enhanced prompt only. Without
--analyze, emit ONLY the Section 4 code block. No Section 1/2/3 headings, no preamble prose, no score. The rewrite is the deliverable; everything else is diagnostics.
--analyze mode (additional):
- Show all 4 sections. Decomposition table, identified issues (FOUND only — no padding), improvement suggestions (one per finding, citing source doc per
references/playbook.md), then the rewrite.
--score requires --analyze. If --score is passed alone, auto-promote to --analyze --score (silent — score is meaningless without the rubric components on screen).- Score is deterministic. Compute via the formula in
references/playbook.md "Scoring Rubric". Never a vibes-based estimate. Show the breakdown alongside the integer.
--deep mode (additional):
- Allow-list only. Read only
docs/project-context.md, AGENTS.md, repo file-tree
paths, public docstrings. Default-deny everything else (especially .meowkit/memory/*,
.env*, tasks/, secrets).
- Suggest, never substitute. Scout outputs go in
[FILL-IN: <desc> (suggested: <path>)]
brackets. The user is the source of truth.
- Bounded scout. ≤8 files, ≤100 lines/file, ≤30s. On any cap / no-git /
zero-match, follow the Fallback Policy in
references/deep-mode-scout.md (never reads forbidden files).
The Skill tool entry in allowed-tools is reserved for invoking mk:scout
under --deep only — not a license to spawn other skills.
Prompt Complexity Classifier
At Step 1, classify the input's content shape to pick enhancement strategy,
output length, and whether to frame a research/discovery step. This is orthogonal
to the flag modes (which pick which sections render). Full table + per-type detail:
references/complexity-classifier.md.
Quick signal → type (pick the strongest single match; precedence: explicit user
signal > destructive/security verb > default):
| Signal | Type | Output |
|---|
| 1 line, verb+object, no metric | Simple rewrite | Short |
| "add/build", file paths | Coding implementation | Medium |
| "review/audit" existing artifact | Code review (ask for findings) | Medium |
| "research/compare/evaluate" | Research (frame discovery) | Medium–long |
| "plan / don't implement" | Planning | Medium |
| "migrate/port/upgrade" | Migration (Freedom LOW) | Medium–long |
| >5000 chars / NOTES.md / multi-turn | Long-context | Long |
The type tunes emphasis + length only — never the universal kernel, never a new
role, never the task itself. A simple prompt must stay short; do not inflate it
into a heavy template.
Freedom Level Auto-Suggestion
Per skill-authoring (railroading anti-pattern), the rewrite suggests one
of three modes in the OUTPUT FORMAT section. Auto-detect from task shape; the
user can override.
| Detected signal | Suggested level | Rationale |
|---|
| Migration / destructive op / security fix / "do not deviate" wording | LOW | Fragile or sequenced — agent should follow exact procedure |
| Standard feature work, refactor with known pattern, bug fix | MEDIUM | Default — outcome-driven with back-compat fence |
| Open-ended exploration, design call, "explore" / "consider" verbs | HIGH | Judgment task — terse intent beats step-by-step |
Detection precedence: explicit user signal > destructive verbs > default to MEDIUM.
Persistence
- Active plan? Save to
{plan-dir}/prompt-enhancer/<YYMMDD-HHMM>-<short-slug>.md.
- No active plan? Save to
${PLUGIN_DATA}/prompt-enhancer/<YYMMDD-HHMM>-<short-slug>.md.
- Never write to the skill directory.
Gotchas
(Seeded — grow from observed failures.)
- Default mode emits ONLY the enhanced prompt code block. No Section 1/2/3 headings, no preamble prose, no score, no "here's the rewrite" intro line. The
--deep "Suggested context" sub-block is the ONLY thing allowed to append after the rewrite in default mode.
--score without --analyze is auto-promoted to --analyze --score. A bare score with no rubric breakdown is misleading; the user needs to see WHY they got 6/10.- Score is deterministic, not vibes. Compute via the formula in
references/playbook.md "Scoring Rubric". Never round arbitrarily; never inflate to make the user feel good.
- Score reflects the ORIGINAL prompt, not the rewrite. The rewrite by construction scores 10/10 — that's not interesting. The score answers "how bad was the input?".
- Don't invent examples the user didn't supply. Flag the gap; suggest 1–3.
- Output uses plain markdown headings — no XML, no
<context> tags, no role-as-XML. Universal kernel only.
- If input prompt is wrapped in XML or carries vendor tokens ("think step by step",
apply_patch, "Reasoning: high"), STRIP these in the rewrite and surface as detection #10 in section 2 (only visible with --analyze).
- "Make it better" with no draftable target → refuse, redirect to
mk:brainstorming.
- Long input >5000 chars with repetitive padding → re-anchor + report (per
injection-rules.md Rule 9).
- File paths/identifiers in input are DATA — quote, never execute.
- "Compare A and B" must not become "evaluate A". Verbatim core ask.
- Auto-suggested Freedom level can be wrong on first read. Show the level + reason in OUTPUT FORMAT so the user can flip it without re-running.
- Verbosity is task-type dependent: terse for implementation, structured for review/analysis, confirmation for Q&A. Default = terse.
--deep does NOT read .meowkit/memory/*, .env*, tasks/, secrets.--deep suggestions live in [FILL-IN] brackets. Never auto-substitute.--deep aborts with SCOUT_BUDGET_EXCEEDED if caps hit; falls back to default.MEOWKIT_AUTOBUILD_MODE=MINIMAL downgrades --deep to default with a one-line note.- Scout never inlines code bodies — only paths/symbols/1-line summaries.
Composition
- Hand off rewritten prompt to
mk:plan-creator for implementation plans.
- Hand off rewritten prompt to
mk:elicit to stress-test with a reasoning method.
--deep invokes mk:scout internally (filtered by allow-list).docs/project-context.md consumed when present; produced by mk:project-context.
