spec-kitty-glossary-context

Maintain semantic integrity by curating the project glossary, detecting term drift, and ensuring that all mission artifacts use canonical terminology.

Use this skill when the user wants to inspect, update, or enforce glossary terms. Do not use it for purely operational tasks like advancing the runtime loop or repairing an installation.

How the Glossary Works

The glossary is a semantic integrity runtime — a 5-layer middleware pipeline that intercepts mission step execution, extracts terms from inputs/outputs, checks them against stored definitions, and can block generation if terminology conflicts are unresolved.

Data Model

Terms have a surface (normalized to lowercase), definition, scope, confidence (0.0–1.0), and status (draft/active/deprecated).

Seed files (.kittify/glossaries/{scope}.yaml) provide initial definitions. Event logs (.kittify/events/glossary/*.events.jsonl) record all runtime mutations as append-only JSONL. State is reconstructed by replaying seed files then events.

4 Scopes (narrowest wins)

The 5-Layer Middleware Pipeline

When a mission primitive executes (via @glossary_enabled decorator or GlossaryAwarePrimitiveRunner), this pipeline processes the step:

Layer 1 — Term Extraction. Scans step input/output for terminology using multiple methods (in priority order):

Emits TermCandidateObserved events.

Layer 2 — Semantic Check. Resolves each extracted term against the scope hierarchy and classifies conflicts:

Emits SemanticCheckEvaluated events.

Layer 3 — Clarification (runs BEFORE the gate). Users get a chance to resolve conflicts before generation is blocked:

• In interactive mode: prompts user to select a candidate sense, provide a custom definition, or defer
• In non-interactive mode (CI/headless): auto-defers all conflicts
• Resolved conflicts are removed; deferred ones pass to Layer 4

Emits GlossaryClarificationRequested, GlossaryClarificationResolved, and GlossarySenseUpdated events.

Layer 4 — Generation Gate. Evaluates whether to block based on strictness:

Strictness resolved via 4-tier precedence: runtime flag > step metadata > mission config > global default (.kittify/config.yaml).

If blocking: saves a checkpoint (SHA256 input hash, scope versions, retry token), emits StepCheckpointed and GenerationBlockedBySemanticConflict events, then raises BlockedByConflict.

Layer 5 — Resume. For retry after a block:

• Loads checkpoint from event log
• Verifies input hash hasn't changed (detects context drift)
• Prompts user if context changed
• Restores execution state

Step-Level Configuration

Individual mission steps can control glossary behavior via metadata:

# In step definition
glossary_check: enabled          # or "disabled" to skip this step
glossary_check_strictness: max   # override strictness for this step
glossary_watch_terms:            # explicit terms to monitor (confidence 1.0)
  - work package
  - lane
glossary_aliases:                # map synonyms to canonical forms
  task: work package
  status: lane
glossary_exclude_terms:          # terms to ignore
  - the
  - a

8 Event Types

All events are append-only in .kittify/events/glossary/{mission-id}.events.jsonl.

Integration Patterns

# 1. Decorator (simplest)
@glossary_enabled(repo_root=Path("."))
def my_primitive(context):
    return {"result": "ok"}

# 2. Function processor
processor = attach_glossary_pipeline(repo_root, runtime_strictness, interaction_mode)
processed_context = processor(context)  # May raise BlockedByConflict

# 3. Runner class
runner = GlossaryAwarePrimitiveRunner(repo_root, runtime_strictness)
result = runner.execute(primitive_fn, context)

The BlockedByConflict exception carries the conflicts list, strictness mode, and a user-facing message. Callers should catch it, present the conflicts, and offer resolution before retrying.

Step 1: Locate Glossary Context

Identify the glossary state for the current project.

What to check:

• Seed files under .kittify/glossaries/ (one YAML per scope)
• Event logs under .kittify/events/glossary/ (JSONL, event-sourced)
• The store replays seed files then events at query time

Commands:

spec-kitty glossary list
spec-kitty glossary list --scope spec_kitty_core
spec-kitty glossary list --status active --json

Expected outcome: You know which scopes are populated and whether event logs contain runtime mutations.

Step 2: Check Conflicts and Strictness

The glossary gates mission execution through the strictness system.

Commands:

spec-kitty glossary conflicts
spec-kitty glossary conflicts --unresolved
spec-kitty glossary conflicts --strictness max --mission 012-documentation-mission

Expected outcome: You understand why a conflict blocked the runtime, or you can confirm no blocking conflicts exist.

Step 3: Update Terms and Resolve Conflicts

Adding or editing terms: Edit the seed file for the appropriate scope.

Choose the scope by term ownership:

• Project-internal jargon: mission_local.yaml
• Shared domain vocabulary: team_domain.yaml
• User-facing terms: audience_domain.yaml
• Spec Kitty concepts: spec_kitty_core.yaml (rarely edited)

Rules: surface must be lowercase/trimmed; status is active, deprecated, or draft; confidence is 0.0–1.0.

Seed file format:

terms:
  - surface: <lowercase trimmed string>
    definition: <non-empty string>
    confidence: <float 0.0-1.0>       # default 1.0
    status: <active|deprecated|draft>  # default draft

Status lifecycle: draft → (promote) → active → (retire) → deprecated → (re-draft) → draft. Deprecated senses are excluded from resolution but remain in event history.

Resolving conflicts interactively:

spec-kitty glossary resolve <conflict_id>
spec-kitty glossary resolve <conflict_id> --mission 012-docs

The resolver presents candidate senses. You can select one, enter a custom definition, or defer. Custom definitions emit both a GlossaryClarificationResolved and a GlossarySenseUpdated event.

Expected outcome: The glossary reflects intended terminology and runtime- blocking conflicts are resolved.

Step 4: Detect and Prevent Semantic Drift

Semantic drift occurs when artifacts gradually diverge from glossary definitions. See references/semantic-drift-examples.md for six concrete drift patterns.

Detection:

1. Run spec-kitty glossary list --json and compare definitions against spec, plan, and task files
2. Run spec-kitty glossary conflicts --unresolved for terms the runtime flagged
3. Search WP frontmatter for informal synonyms (e.g., "task" instead of the canonical "work package")

Correction:

• Artifact is wrong: replace with the canonical term
• Glossary is outdated: update the seed file definition
• Genuinely ambiguous: add a second sense and let the strictness system force disambiguation

Prevention:

• Set strictness to medium or max so the runtime catches conflicts early
• Add domain terms to the glossary before writing specs that use them
• Use glossary_watch_terms in step metadata for high-value terms
• Use glossary_aliases to map known synonyms to canonical forms
• Review the conflict log after each completed mission

Consistency checklist:

1. Every WP title and description uses canonical surface forms
2. Plan documents reference terms as defined in the glossary
3. No informal synonyms appear without a corresponding glossary entry
4. Deprecated terms are not reintroduced in new artifacts

Expected outcome: Terminology is consistent across all mission artifacts and the glossary remains a living, enforced contract.
