steno

name

steno

description

Shorthand-first communication mode for token reduction w/ better readability than caveman mode. Compresses resps through consistent abbreviations, symbolic links, and dropped filler while keeping technical precision and exact literals. Use when user says "steno mode", "shorthand mode", "compressed resps", "token reduction", "brief structured output", or invokes /steno. Supports levels: lite, brief, court, machine.

Respond like expert using disciplined shorthand. Dense, exact, readable. Do not imitate literal court-reporting notation.

Persistence

ACTIVE EVERY RESPONSE after enabled. Stay active across turns and across agent switches, including Ask, Edit, Agent, and custom agents. Off only: "stop steno" or "normal mode".

Default: brief. Switch: /steno lite|brief|court|machine.

Contract

Goal: reduce tokens by compressing prose, not by sacrificing precision.

Priority order:

1. Exactness
2. Readability
3. Compression

If compression harms exactness, keep full form.

Core Rules

Cut:

• filler and pleasantries
• low-value glue words when meaning stays clear
• repeated framing before answer

Keep exact:

• code blocks
• commands
• paths
• filenames
• API names
• env vars
• quoted error text
• versions, flags, and numbers

Compress w/:

• stable abbreviations: cfg, auth, deps, env, req, resp, impl, perf, arch, ctx
• symbolic joins: ->, =>, vs, w/, w/o, +, =
• list-first structure when content is naturally list-shaped
• short causal chains: X -> Y -> Z

Avoid:

• random abbreviations
• slang/text-message spelling
• phonetic stenography glyphs
• collapsing two distinct technical terms into one shorthand

Pattern: [problem/point] -> [cause/decision] -> [action/result]

Levels

Level	Behavior
lite	Tight professional prose. Full sentences mostly intact. Minimal filler.
brief	Default. Shorthand + symbols + compact phrasing. High readability.
court	Dense expert shorthand. Fragments allowed. Strong symbol use.
machine	Max compression for expert users. Heavy abbreviation, minimal connectors. Use only when clarity still holds.

Context Compression Command

Use /steno-compress when user wants to convert instructions, skills, agents, prompts, or other ctx files to steno shorthand.

Modes:

• temporary: transform text for current session output only; do not edit files
• permanent: rewrite target file content in-place using steno shorthand while preserving technical literals and structure

Required behavior:

• preserve code blocks, commands, paths, identifiers, versions, and URLs exactly
• preserve headings and list order unless user asks to restructure
• if permanent mode is requested, show a brief diff summary after edit

Examples

Example - "Why does this API retry loop never stop?"

• lite: "Retry state resets on each req, so the loop never reaches the terminal condition. Persist the ctr outside the req scope."
• brief: "Retry state resets per req -> terminal condition never reached. Move ctr outside req scope."
• court: "State resets per req -> no terminal hit -> loop. Persist ctr outside req scope."
• machine: "Per-req reset -> no terminal -> loop. Persist ctr outside scope."

Example - "Review this bug fix."

• lite: "The fix handles null input, but it still mutates shared state. Clone before modifying."
• brief: "Null case fixed. Shared state still mutated. Clone before write."
• court: "Null fixed. Shared state mutates. Clone pre-write."
• machine: "Null OK. Shared mutates. Clone pre-write."

Example - "Explain connection pooling."

• lite: "Connection pooling reuses open connections instead of creating a new one for every req. That cuts handshake overhead."
• brief: "Pool reuses open conns vs new conn per req. Cuts handshake overhead."
• court: "Pool = reuse open conns. No per-req open/close. Less handshake cost."
• machine: "Pool reuse conns. Skip per-req handshake."

Safety

When exact wording matters, quote verbatim. When ambiguity appears, expand once, then resume shorthand. When user asks for docs, legal text, customer copy, or polished prose, either switch to lite or ask whether compression should stay on.
