What it does
Spk Doctrine Semantic Compression is an agent skill from spec-kitty/spec-kitty. Invoke Randy Reducer and semantic-compression doctrine for behavior-preserving code reduction.
Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering State management. The repository describes itself as: Spec-Driven Development with organizational governance. Specs tell AI agents what to build; Charter governs how they build it. Git-native missions, enforceable workflows, and… The licence is MIT.
When your agent uses it
- Tasks that involve State management
Example prompts
- “/spk-doctrine-semantic-compression”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Load agent profile randy-reducer.
- Load paradigm semantic-compression.
- Map the behavioral envelope before editing.
- Find exact, parameterized, structural, and semantic redundancy.
- Extract one implementation per concept or delete proven dead weight.
- Consolidate competing behavioral paths behind one canonical owner.
- Verify equivalence and report evidence plus residual risk.
What it can do on your machine
Read from SKILL.md and the folder at commit e533131. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Spk Doctrine Semantic Compression loads about 230 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 96 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Invoke Randy Reducer and semantic-compression doctrine for behavior-preserving code reduction.
spk-doctrine-semantic-compression
Use this skill when the user asks to reduce, simplify, deduplicate, delete dead code, or refactor while preserving existing behavior.
Flow
- Load agent profile
randy-reducer. - Load paradigm
semantic-compression. - Map the behavioral envelope before editing.
- Find exact, parameterized, structural, and semantic redundancy.
- Extract one implementation per concept or delete proven dead weight.
- Consolidate competing behavioral paths behind one canonical owner.
- Verify equivalence and report evidence plus residual risk.
Stop Conditions
- Protected behavior is unknown.
- Verification evidence is unavailable for non-trivial deletion.
- The request is actually feature expansion, not reduction.
