AG Kit is a toolkit that gives Google Antigravity coding agents a structured workspace with rules, skills, specialist agents, workflows, persistent memory, orchestration, MCP guidance, and a safety hook. It is for building and operating agent workflows in Antigravity, and its catalogue entries provide parts of that workspace contract.

SkillSpector: 2 findings, 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 Tool Misuse · line 95 Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
- medium Privilege Escalation · line 95 Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.
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 | $0.00026 | $0.01036 |
| Opus 5 | $0.00013 | $0.00518 |
| Sonnet 5 | $0.00005 | $0.00207 |
| Haiku 4.5 | $0.00003 | $0.00104 |
Grade B, and why
red-team-tactics scanned grade B with 1 finding 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 11d 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.
Harvests environment variablesmediumData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
| **Credential Access** | Harvest credentials | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Red Team Tactics
Adversary simulation principles based on MITRE ATT&CK framework.
1. MITRE ATT&CK Phases
Attack Lifecycle
RECONNAISSANCE → INITIAL ACCESS → EXECUTION → PERSISTENCE
↓ ↓ ↓ ↓
PRIVILEGE ESC → DEFENSE EVASION → CRED ACCESS → DISCOVERY
↓ ↓ ↓ ↓
LATERAL MOVEMENT → COLLECTION → C2 → EXFILTRATION → IMPACT
Phase Objectives
| Phase | Objective |
|---|---|
| Recon | Map attack surface |
| Initial Access | Get first foothold |
| Execution | Run code on target |
| Persistence | Survive reboots |
| Privilege Escalation | Get admin/root |
| Defense Evasion | Avoid detection |
| Credential Access | Harvest credentials |
| Discovery | Map internal network |
| Lateral Movement | Spread to other systems |
| Collection | Gather target data |
| C2 | Maintain command channel |
| Exfiltration | Extract data |
2. Reconnaissance Principles
Passive vs Active
| Type | Trade-off |
|---|---|
| Passive | No target contact, limited info |
| Active | Direct contact, more detection risk |
Information Targets
| Category | Value |
|---|---|
| Technology stack | Attack vector selection |
| Employee info | Social engineering |
| Network ranges | Scanning scope |
| Third parties | Supply chain attack |
3. Initial Access Vectors
Selection Criteria
| Vector | When to Use |
|---|---|
| Phishing | Human target, email access |
| Public exploits | Vulnerable services exposed |
| Valid credentials | Leaked or cracked |
| Supply chain | Third-party access |
4. Privilege Escalation Principles
Windows Targets
| Check | Opportunity |
|---|---|
| Unquoted service paths | Write to path |
| Weak service permissions | Modify service |
| Token privileges | Abuse SeDebug, etc. |
| Stored credentials | Harvest |
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.
- 11d ago First seen · 202 lines · 26 tokens per session scan B fc3e8f0fe1f6
red-team-tactics is a skill published in the GitHub repository vudovn/ag-kit (8,174 stars, last pushed 4d ago), licensed MIT. It adds 26 tokens to every session and 1,036 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
