A feature-management tool for an existing Mozaiks application. Mozaiks is a platform for building applications from predefined backend and frontend components.

It helps enable chat interfaces, backend modules, event communication, authentication, administration tools, or preset feature tiers in a Mozaiks project.

It gives developers a defined way to add individual capabilities or enable a group of capabilities at once. This avoids manually working out which related parts a chosen tier needs.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Privilege Escalation · line 103
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00022	$0.01234
Opus 5.5	$0.00009	$0.00494
Sonnet 5.5	$0.00004	$0.00247
Haiku 4.5	$0.00002	$0.00123

Security

Grade A, and why

add-feature scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 21d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Before starting: git fetch origin && gh pr list --state open && git log origin/main --oneline -3 — if another agent has an open PR touching the same files you need, wait for it to merge, then branch from fresh origin/main.

modules	Deterministic CRUD/action modules and module routes	-
event_bus	Domain event bus for module↔workflow communication	-
auth	Provider-neutral OIDC/JWT validation and browser PKCE auth	OIDC provider or local mock
admin	Admin portal with observability, token tracking	auth

Tier Presets

Preset	Features Included
engine	ai_runtime
chat	ai_runtime, chat_ui
integrated	ai_runtime, chat_ui, modules, event_bus, auth
full	All features

Commands

Enable Individual Feature

mozaiks add <feature>

Examples:

mozaiks add modules       # Add deterministic module handling
mozaiks add event_bus     # Add event-driven automation
mozaiks add auth          # Add provider-neutral OIDC/JWT authentication
mozaiks add admin         # Add admin portal

Upgrade to Higher Tier

mozaiks add --preset <tier>

- Adds feature override OR upgrades preset
- Example: {"features": {"modules": true}}
Shows next steps:
- What directories to create
- What config to update
- What services to start

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

add-feature is a skill published in the GitHub repository BlocUnited-LLC/mozaiks (24 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 1,234 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
