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 | $0.00021 | $0.00159 |
| Opus 5 | $0.00010 | $0.00079 |
| Sonnet 5 | $0.00004 | $0.00032 |
| Haiku 4.5 | $0.00002 | $0.00016 |
Grade A, and why
start-fb 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 6d 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.
What it actually says
Arguments received: $ARGUMENTS (expected: FB name + one-line description; if empty, ask the user).
Follow the workflow defined in the writing-st-code skill (.claude/skills/writing-st-code/SKILL.md) using these arguments.
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.

start-fb is a command published in the GitHub repository efranceschetti/festo-codesys-mcp (1 stars, last pushed 11d ago), licensed MIT. It adds 21 tokens to every session and 159 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
Other commands, from other repositories
equipment-maint
Schedule preventive maintenance for critical ED equipment using MTBF (Mean Time Between Failures) data and predictive failure analysis. Reduces unplanned downtime and optimizes maintenance costs.
isolate-emi-culprit
Localise the device or sub-system causing an emissions failure or radio-receiver interference. Uses a structured bisection (swap-out + proximity + spectral signature) rather than free-form swap-everything debugging.
map-near-field
Execute a structured near-field scan over a device-under-test (DUT) or board, producing a calibrated 2D or 3D field map for EMC investigation, PCB hot-spot work, or antenna near-field characterisation.
comms-redundancy-audit
Audit primary + alternate + emergency communications (P25, GSM, satellite, runner protocols) against the trip's routes and venues — identify dead zones, single-points-of-failure, and protocol gaps.
parts-research
Research parts for your specific application — compatibility, expected gains, reliability trade-offs, and sourcing.
incident-response
Activate structured incident response for a suspected control system compromise.
