UniKit Skills — Skill Context Management

Add workflow rules to .unikit/skill-context/<skill>/SKILL.md. These are project-level overrides that change how built-in unikit skills behave in this specific project.

When to use skill-context vs RULES.md:

• RULES.md (via /unikit-rules) — coding conventions: HOW to write code (naming, patterns, style)
• Skill-context (this skill) — workflow overrides: HOW a skill should work (priorities, steps, guards)

Language Awareness — BLOCKING PRE-REQUISITE

BEFORE producing ANY output, silently read .unikit/system/LANGUAGE_RULES.md and apply its rules to ALL subsequent output. If the file is missing or unreadable, fall back to English. Do not produce any user-facing output until language rules are loaded. Do not announce, confirm, or mention the language setting.

The language holds for the whole session, not just at load time: every message until the conversation ends is in language.ui — progress notes while agents run, relays of what a subagent returned, the final report, any follow-up discussion. English input (subagent results, tool output, these instructions) is data, never a cue to switch languages.

Critical: Never Edit Built-in Skills Directly

NEVER modify files inside {{skills_dir}}/unikit-*/.

ALWAYS write to: .unikit/skill-context/<skill-name>/SKILL.md

Workflow

Step 0: Determine Mode

Check $ARGUMENTS:
├── starts with "validate" → Validate Mode
├── <skill-name> <rule-text> → Mode A: Direct Add
└── No arguments → Mode B: Interactive

Parsing arguments:

• Mode detection: If first word is validate → Validate Mode. Otherwise → Add Mode.
• Add Mode: First token = skill name, rest = rule text.
• Validate Mode: validate alone → all skills. validate <skill> → specific skill.

Skill name normalization (applies to all modes):

User input	Resolved
review	unikit-review
unikit-review	unikit-review
/unikit-review	unikit-review
my-custom-skill	my-custom-skill

Rule: strip leading /. If name doesn't start with unikit- AND {{skills_dir}}/unikit-<name>/SKILL.md exists → use unikit-<name>. Otherwise use as-is.

After resolving: verify {{skills_dir}}/<resolved>/SKILL.md exists. If not → error: "Skill '<resolved>' not found. Available unikit skills: [scan {{skills_dir}}/unikit-*/SKILL.md for installed skills]."

---

Mode A: Direct Add

User provided skill name and rule text:

/unikit-skills-context review "Always check null-check symmetry first"

Proceed to Step 1 with resolved skill name and rule text.

Mode B: Interactive

No arguments provided.

AskUserQuestion: Which skill do you want to customize, and what rule should be added?

Skill-context rules change HOW a skill works — priorities, steps, guards. For coding conventions (naming, patterns), use /unikit-rules instead.

Examples:

• review "Always check null-check symmetry first"
• fix "When fixing async bugs, check cancellation cleanup"
• implement "Compile after each file change"

After user responds, parse skill name and rule text, then proceed to Step 1.

---

Step 1: Cross-Check Against Base SKILL.md

Read the base skill file: {{skills_dir}}/<resolved>/SKILL.md

Check if the base SKILL.md already covers the proposed rule:

Situation	Action
Base already contains this exact instruction	Tell user: "Already covered in base skill: {quote}". Skip.
Base has a weaker version of same instruction	Add to skill-context as strengthened override. Note what it strengthens.
Base contradicts the proposed rule	Add to skill-context as explicit override. Warn that skill-context wins over base.
No overlap with base	Add to skill-context as new rule.

Step 2: Cross-Check Against Existing Skill-Context

Read .unikit/skill-context/<skill>/SKILL.md if it exists.

Check for semantic duplicates — if a rule with the same meaning already exists in skill-context, tell user and skip.

Step 3: Add Rule to Skill-Context

If file doesn't exist — create directory and file:

mkdir -p .unikit/skill-context/<skill-name>

# Project Rules for /<skill-name>

> Auto-generated by `/unikit-skills-context`. Do not edit manually.
> Last updated: YYYY-MM-DD HH:mm

## Rules

### [Rule Name]
**Rule**: [Specific, actionable instruction in English]

If file exists — read it, then:

• Add new ### [Rule Name] entry under ## Rules
• Update > Last updated: line

Formatting:

• Rule name: short, descriptive (2-5 words)
• Rule text: English, imperative, specific and actionable
• If user provided rule in non-English language, translate to English before writing

Step 4: Confirm

✅ Added to .unikit/skill-context/<skill>/SKILL.md:

### [Rule Name]
**Rule**: [the rule text]

Cross-check: [result — "no overlap with base" / "strengthens base rule on X" / "overrides base behavior Y"]

---

Validate Mode: Stale Rule Check

Triggered by:

• /unikit-skills-context validate → check ALL skills that have skill-context files
• /unikit-skills-context validate <skill> → check specific skill only

Step V1: Find Skill-Context Files

Glob: .unikit/skill-context/*/SKILL.md

If checking specific skill → filter to that one.

If no skill-context files found → report "No skill-context files to validate." and stop.

Step V2: Compare Against Base Skills

For each skill-context file:

1. Read the base {{skills_dir}}/<skill>/SKILL.md
2. For each rule in skill-context, compare against the base:

Case	Description	Recommendation
A: Fully covered	Base now contains equivalent or superset rule	Remove from skill-context — base handles it
B: Conflict	Base directly contradicts skill-context rule	User decision required — skill-context wins if kept
C: Partial overlap	Neither fully covers the other	Analyze and present options
D: No overlap	Rule is unique to project context	Keep as-is, no action needed

Collect all Case A/B/C findings. If none found → report "All skill-context rules are current." and stop.

Step V3: Present Findings

For each stale rule:

Case A — Fully covered:

### ✅ /unikit-<skill> — Fully covered: [Rule Name]
- **Base SKILL.md says:** [base rule text]
- **Skill-context says:** [project rule text]
- **Recommendation:** Remove from skill-context (base covers it)

Case B — Conflict:

### ⚠️ /unikit-<skill> — Conflict: [Rule Name]
- **Base SKILL.md says:** [base rule text]
- **Skill-context says:** [project rule text]
- **Note:** Skill-context has priority — if kept, base version is ignored

Case C — Partial overlap:

### 🔄 /unikit-<skill> — Partial overlap: [Rule Name]
- **Base SKILL.md says:** [base rule text]
- **Skill-context says:** [project rule text]
- **Analysis:** [explain overlap and whether parts are independent]
- **Warning:** Skill-context has priority — if kept as-is, base's unique parts on this topic will be lost

Step V4: Collect Decisions

Use AskUserQuestion in batches of up to 3:

Case A:

Options:

1. Remove — trust base skill
2. Keep — ensure priority of skill-context rule

Based on choice:

• Remove → delete the rule section from skill-context file
• Keep → no changes needed

Case B:

Options:

1. Keep skill-context — override base
2. Remove — trust base
3. Rewrite — merge both formulations

Based on choice:

• Keep skill-context → no changes needed
• Remove → delete the rule section from skill-context file
• Rewrite → replace rule text with merged version

Case C:

Options:

1. Rewrite — include unique parts from both
2. Keep as-is — base's parts lost
3. Remove — delete skill-context rule

Based on choice:

• Rewrite → replace rule text with new version combining both
• Keep as-is → no changes needed
• Remove → delete the rule section from skill-context file

Step V5: Apply Decisions

For each decision:

• Remove: Delete the rule section from skill-context file
• Rewrite: Replace rule text with new version
• Keep: No changes needed

After applying:

• Update > Last updated: line
• If a skill-context file has no rules left (only header remains) → delete the file and its directory

Rules

1. Skill-context only — all rules go to .unikit/skill-context/, NEVER to {{skills_dir}}/unikit-*/
2. English only — skill-context files are always in English regardless of user's language
3. Workflow rules only — skill-context is for HOW skills work, not coding conventions (use /unikit-rules for those)
4. No duplicates — always cross-check against base SKILL.md and existing skill-context
5. Reversible — user approves changes in validate mode before applying
6. Ownership boundary — this command owns .unikit/skill-context/*; treats base skills ({{skills_dir}}/) and rules (.unikit/memory/, .unikit/RULES.md, .unikit/rules/) as read-only

Examples

/unikit-skills-context review "Always check null-check symmetry first"

> ✅ Added to .unikit/skill-context/unikit-review/SKILL.md:
> ### Null-Check Priority
> **Rule**: Always check null-check symmetry first when reviewing code.
> Cross-check: no overlap with base

/unikit-skills-context validate

> 🔍 Checking 2 skill-context files...
>
> ✅ /unikit-fix — Fully covered: Cancellation Cleanup
> Base SKILL.md now includes: "check cancellation cleanup in async methods"
> Recommendation: Remove from skill-context
>
> ✅ /unikit-review — No overlap: all 3 rules are project-specific
>
> ⚠️ 1 stale rule found. Remove? (Yes / Keep)
