What it does
Continuity is an agent skill from parcadei/Continuous-Claude-v3. Problem-solving strategies for continuity in real analysis
Its SKILL.md is about 290 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 Research & Science, covering Math and symbolic computation. It works with SymPy. The repository describes itself as: Context management for Claude Code. Hooks maintain state via ledgers and handoffs. MCP execution without context pollution. Agent orchestration with isolated context windows. The licence is MIT.
When your agent uses it
- Tasks that involve Math and symbolic computation
Example prompts
- “/continuity”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash, Read
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Check Definition
- Use SymPy for Limit Check
- Piecewise Functions
- Verify with Z3
What it can do on your machine
Read from SKILL.md and the folder at commit d07ff4b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashRead
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
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
Continuity loads about 292 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 89 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, Read
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.

Continuity
When to Use
Use this skill when working on continuity problems in real analysis.
Decision Tree
Check Definition
- f(a) exists (function defined at point)
- lim_{x->a} f(x) exists
- lim_{x->a} f(x) = f(a)
Use SymPy for Limit Check
sympy_compute.py limit "f(x)" --var x --at a- Compare with f(a)
Piecewise Functions
- Check left and right limits separately
sympy_compute.py limit "f(x)" --var x --at a --dir left
Verify with Z3
z3_solve.py prove "limit_exists implies continuous"
Tool Commands
Sympy_Limit
uv run python -m runtime.harness scripts/sympy_compute.py limit "f(x)" --var x --at aSympy_Limit_Left
uv run python -m runtime.harness scripts/sympy_compute.py limit "f(x)" --var x --at a --dir leftZ3_Prove
uv run python -m runtime.harness scripts/z3_solve.py prove "continuous_at_a"Cognitive Tools Reference

Questions about Continuity
What does Continuity do?
Problem-solving strategies for continuity in real analysis. An agent skill from parcadei/Continuous-Claude-v3. Continuity is an agent skill from parcadei/Continuous-Claude-v3.
When should I use Continuity?
Continuity fits situations like: tasks that involve Math and symbolic computation.
How do I install Continuity in Claude Code?
Run `npx skills add parcadei/Continuous-Claude-v3 --skill continuity -a claude-code`. Or copy the skill folder (.claude/skills/math/real-analysis/continuity in parcadei/Continuous-Claude-v3) into .claude/skills/continuity in your project. Claude Code loads it when a task matches its description.
How do I install Continuity in Codex?
Run `npx skills add parcadei/Continuous-Claude-v3 --skill continuity -a codex`. Or copy the skill folder (.claude/skills/math/real-analysis/continuity in parcadei/Continuous-Claude-v3) into .agents/skills/continuity in your project. Codex loads it when a task matches its description.
Can I use Continuity in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add parcadei/Continuous-Claude-v3 --skill continuity -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/continuity, .gemini/skills/continuity, .github/skills/continuity and .opencode/skills/continuity in your project.
What does Continuity need to run?
Going by SKILL.md and its folder, Continuity needs the command-line tools its instructions call (uv). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Bash, Read.
Does Continuity access the network?
SKILL.md contains no URLs. Its commands use uv, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Continuity safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Continuity use?
Continuity is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Continuity use?
About 292 tokens (SKILL.md is roughly 1.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
