What it does
Cas Search is an agent skill from codingagentsystem/cas. Search across CAS content (memories, tasks, rules, skills, code). Use when needing to find information, understand codebase, or locate specific patterns. Supports hybrid BM25+semantic search, code symbol search, grep, context, and entity operations.
Its SKILL.md is about 520 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 Development, covering Codebase onboarding. It works with Model Context Protocol. The repository describes itself as: Multi-agent orchestration for Claude Code. Persistent memory, tasks, rules, and skills that make AI agents actually coordinate. The licence is MIT.
When your agent uses it
- Needing to find information
- Understand codebase
- Locate specific patterns
Example prompts
- “/cas-search”
What it can do on your machine
Read from SKILL.md and the folder at commit a0a4b5a. 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
Cas Search loads about 516 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 179 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.

CAS Search
Use mcp__cas__search to find information across CAS content and code. Choose the right action for the job:
Which Action to Use
search — Conceptual queries across memories, tasks, rules, skills:
mcp__cas__search action=search query="authentication flow" doc_type=entryFilter with doc_type (entry, task, rule, skill, code_symbol, code_file) for better relevance.
code_search — Find code symbols by what they do, not exact names:
mcp__cas__search action=code_search query="user authentication" kind=function language=rustUse include_source=true to get source code inline.
grep — Exact regex pattern matching in files:
mcp__cas__search action=grep pattern="TODO:" glob="*.rs"Prefer the built-in Grep tool for simple patterns where you already know file paths.
Decision Guide
| Need | Action |
|---|---|
| "How does X work?" | search or code_search |
| Find exact string or regex | grep |
| Find past learnings | search with doc_type=entry |
| Find function by concept | code_search |
| Find related tasks | search with doc_type=task |
Other Actions
context— Session context summary: recent activity, active tasks, relevant memoriescontext_for_subagent— Task-focused context for spawning subagents (passtask_idandmax_tokens)observe— Record discoveries/decisions during work (observation_type: general, decision, bugfix, feature, refactor, discovery)entity_list/entity_show— Browse extracted entities (person, project, technology, etc.)code_show— Full details for a specific code symbol by IDblame— Git blame with optional AI-line filtering (file_path,line_start,line_end)
