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.

Security

Grade A, and why

unflick-navigate 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 2d 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.

unflick: find the moment, then go to it

Seeking by seconds is a poor way to find a scene. unflick can seek by what was said, by chapter, and by a name the user gave a spot earlier.

By what was said

The player reads the subtitle track it already has open — embedded, sidecar, or one whisper.cpp generated (see the unflick-subtitles skill).

  • search_transcript(query, limit?) — every match with its timestamp.
  • seek_to_text(query, occurrence?) — jump to a match. Lands just before the line so the user hears it from the start.
  • transcript_get() — the whole transcript as timed cues.
unflick transcript search "the treasure"
unflick transcript seek "the treasure" --occurrence 2

If there is no readable subtitle track, these say so — generate one first rather than guessing at timestamps.

By chapter

  • chapter_list(), chapter_seek(index), chapter_next(), chapter_prev().
  • generate_chapters(count?) — derive chapters from pauses in the transcript when the file has none of its own.
  • set_chapters(chapters) — supply a list you wrote yourself: [{"time": 0, "title": "Cold open"}, …].

Generated and supplied chapters are real navigation, not a side note: they mark the progress bar and answer chapter_seek. They are cleared when the file changes, so set them for the file that is playing now.

By name

  • bookmark_add(name?, position?, file?) — defaults to where playback is.
  • bookmark_list(file?, all?), bookmark_goto(id) — seeks within the current file, or opens the bookmarked file if it is a different one.
  • bookmark_rename(id, name), bookmark_remove(id), bookmark_clear(…).
unflick bookmark add --name "the good bit"
unflick bookmark list
unflick bookmark goto 1

Bookmarks survive restarts. They are keyed by path — for a disc that means the drive letter, so a bookmark left on one DVD will be offered on the next disc in that drive.

Guidance

  • Prefer seek_to_text over arithmetic on get_status.position: the user asked for a line, not a number.
  • Repeated bookmark_add within a second is treated as a correction of the same spot, not a second bookmark — say so rather than reporting two.
  • bookmark_clear refuses to guess "everything": pass a file, or all.

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.
