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 | $0.00000 | $0.01444 |
| Opus 5 | $0.00000 | $0.00722 |
| Sonnet 5 | $0.00000 | $0.00289 |
| Haiku 4.5 | $0.00000 | $0.00144 |
Grade A, and why
habitat scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Habitat VICE Automation
Launch VICE, automate the Habitat C64 client boot sequence, and debug game memory.
Usage
Use vice_tool.py in the project root to automate VICE. Write and run Python scripts that import VICESession.
Full boot (through launcher)
from vice_tool import VICESession
with VICESession(verbose=True) as v:
v.boot_to_game("steve")
# Game is now running — inspect state
regs = v.registers()
print(f"PC=${regs['PC']:04X}")
print(f"saved_acia_flag = ${v.read_byte(0x6DD9):02X}")
Direct boot (skip launcher + decompressor)
from vice_tool import VICESession
with VICESession(verbose=True) as v:
v.boot_direct(acia=True, breakpoint=0x7083)
# Stopped at rs232_open — step through
regs = v.registers()
v.step()
regs = v.registers()
print(f"A=${regs['A']:02X}") # Should be $FF if ACIA flag propagated
Step-by-step boot (for debugging launcher stages)
from vice_tool import VICESession
with VICESession(verbose=True) as v:
v.boot_to_splash()
# At splash screen — inspect launcher state
v.dismiss_splash()
# At modem selection — default is SwiftLink
v.switch_to_userport() # Switch to User Port (avoids VICE hang)
# At login prompt
v.login("steve")
v.wait_for_decrunch()
# Game running
Set breakpoints and wait
from vice_tool import VICESession
with VICESession(verbose=True) as v:
v.boot_to_splash()
v.dismiss_splash()
v.switch_to_userport()
# Set a breakpoint before login triggers the boot
v.set_breakpoint(0x0816) # start_of_program
v.login("a")
# Wait for breakpoint hit (up to 120s for decrunch)
resp = v.go_and_wait(timeout=120)
regs = v.registers()
print(f"Hit breakpoint at PC=${regs['PC']:04X}")

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.

habitat is a skill published in the GitHub repository ssalevan/habiclient (11 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,444 tokens. 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.

console-get-logs
Retrieve Unity Editor logs from the MCP plugin's LogCollector, optionally filtered by log type or time window. Useful for debugging and monitoring Editor activity.
editor-application-get-state
Return the current state of UnityEditor.EditorApplication — playmode, paused state, compilation state, and related flags.
console-clear-logs
Clear the MCP log cache (used by 'console-get-logs') and the Unity Editor Console window. Useful for isolating logs to a specific action by clearing the slate first.
profiler-start
Enable Unity's runtime profiler and open the Profiler window. Idempotent: calling when already enabled returns the current enabled state without error.
