gifgrep

A command-line tool for finding GIFs—short looping animations—from Tenor or GIPHY, downloading them, and turning them into still images or frame grids.

In plain words
What is it for?
Use it to search and preview GIFs, download results, extract a frame, or create a PNG sheet showing sampled frames.
Why use it?
It removes the need to search GIF websites manually when you need a reaction image, preview, or visual reference.

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

gifgrep 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 3d 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.

Origin

This is a copy

97% identical to gifgrep — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

gifgrep

Use gifgrep to search GIF providers (Tenor/Giphy), browse in a TUI, download results, and extract stills or sheets.

GIF-Grab (gifgrep workflow)

  • Search → preview → download → extract (still/sheet) for fast review and sharing.

Quick start

  • gifgrep cats --max 5
  • gifgrep cats --format url | head -n 5
  • gifgrep search --json cats | jq '.[0].url'
  • gifgrep tui "office handshake"
  • gifgrep cats --download --max 1 --format url

TUI + previews

  • TUI: gifgrep tui "query"
  • CLI still previews: --thumbs (Kitty/Ghostty only; still frame)

Download + reveal

  • --download saves to ~/Downloads
  • --reveal shows the last download in Finder

Stills + sheets

  • gifgrep still ./clip.gif --at 1.5s -o still.png
  • gifgrep sheet ./clip.gif --frames 9 --cols 3 -o sheet.png
  • Sheets = single PNG grid of sampled frames (great for quick review, docs, PRs, chat).
  • Tune: --frames (count), --cols (grid width), --padding (spacing).

Providers

  • --source auto|tenor|giphy
  • GIPHY_API_KEY required for --source giphy
  • TENOR_API_KEY optional (Tenor demo key used if unset)

Output

  • --json prints an array of results (id, title, url, preview_url, tags, width, height)
  • --format for pipe-friendly fields (e.g., url)

Environment tweaks

  • GIFGREP_SOFTWARE_ANIM=1 to force software animation
  • GIFGREP_CELL_ASPECT=0.5 to tweak preview geometry
Changes

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.
