Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00159 | $0.00696 |
| Opus 5.5 | $0.00064 | $0.00278 |
| Sonnet 5.5 | $0.00032 | $0.00139 |
| Haiku 4.5 | $0.00016 | $0.00070 |
Grade A, and why
timecode-bridge 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 1mo 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 — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Timecode Bridge
Timecode Bridge is an open-source hardware companion that lets Aria Gen 2 glasses time-align with external LTC-timecoded gear — motion capture systems, professional cameras, audio recorders, SMPTE / MTC generators. It decodes SMPTE LTC on a BNC input and re-broadcasts on the same sub-1 GHz radio protocol that Aria's built-in Time Domain Mapping (TDM) already uses.
Single source of truth for hardware, firmware, CLI, calibration, channels, and updates: https://github.com/facebookresearch/projectaria_timecode_bridge
This skill encodes only the stable concept. Fetch the repo for anything specific — board part numbers, CLI flags, channel numbers,
air_delaydefaults, BOM, wiring. Never guess these values.
Mental model
The glasses see no change. The Bridge simply fills the "broadcaster" role that another Aria would otherwise fill:
[LTC source] ── BNC ─► [Timecode Bridge] ── sub-GHz ─► [Aria glasses (Receiver)]
On the glasses side it is standard TDM: configure Receiver mode (via Companion App or Client SDK), match the Bridge's channel and broadcaster ID, and read the aligned timestamps out of the existing SubGHz TimeDomain in the resulting VRS. No new SDK feature, no new API, no new profile setting, no new VRS stream type.
When to answer here vs. redirect
Answer from this skill: what the Bridge is, why it exists, how it fits with the built-in glasses-to-glasses TDM, whether the glasses need new software (they do not).

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.

timecode-bridge is a skill published in the GitHub repository facebookresearch/projectaria-plugins (14 stars, last pushed 6d ago), licensed Apache-2.0. It adds 159 tokens to every session and 696 once invoked, about $0.0006 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 2026-08-31.
