SPEC Prompt Compactor (Retired Archive)

This browser-only research demo is preserved for historical inspection. SPEC failed its current Kiah-shaped go/no-go gates, and its Kiah integration was removed on 2026-08-30.

Compaction is lossy by design. Do not use it for operational or sensitive prompts.

Try These Examples

Polite Filler

"Can you please summarize this information and generate a short response for the assistant?"

Try: Balanced

Code + URL Safe

"Explain this snippet: `SELECT * FROM users WHERE id = 1;` and check https://ottobot.org/projects/spec"

Keeps protected segments

Paths + Tags

"Run llama3.1:8b-instruct-q4_K_M on /data/ai-system/kiah.py and summarize the output."

How SPEC Works

1

Polite Prefix Trimming

Removes common prompt boilerplate like “can you please…” (lossy, but usually safe)

can you please → (removed)
2

Stopword Removal

Drops low-information words to reduce token waste (profile-dependent)

the, and, with → (removed)
3

Protected Segments

Leaves structured content untouched (code blocks, inline code, URLs, emails, paths, quoted strings)

`code`, https://…, /data/…, "quoted" → (unchanged)
4

Profiles

safe keeps more words. balanced removes more. aggressive removes the most.

safe → least lossy
