base-helpCoach mode for the base CLI: teaches what to do and why, rather than just answering.
Base Help is an agent skill from ChristopherKahler/base. Coach mode for the base CLI: teaches what to do and why, rather than just answering. Use for any question about base (how to use it, what it can do for me, star commands, handoffs, forks, rules, domains, recall, AST queries, sync, the graph), or when a base command errors or behaves unexpectedly. Also invoked directly as /base-help [question].
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `README.md`, `references/cli.md` and `references/commands.md`).
It sits in Agent Workflows, covering Context engineering. It works with Model Context Protocol and Rust. The repository describes itself as: AI builder operating system. Turn Claude Code from a per-session tool into a workspace that remembers, maintains itself, and never goes stale. BASE = Builder's Automated State…
2 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit a37b9a8. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditBash(grep *)Bash(rg *)Bash(which base)Bash(base --version)Bash(base doctor)Bash(base help *)Bash(base --help)…and 16 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Base Help loads about 2.6k tokens when it runs, and up to ~78k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 1,282 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.
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.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,282 words (~2,603 tokens).
“The user typed /base-help $ARGUMENTS (or asked a base question). They want to be taught, not just handed a command.”
SKILL.md and 4 other files (references) in claude/skills/base-help of ChristopherKahler/base.

jahala/tilth
Replaces grep, cat, find and ls with the tilth CLI, which returns AST-aware outlines, definitions, usages and callers across many languages in one call.
mksglu/context-mode
Routes large command, file, API and browser output through context-mode tools so only the needed result enters the agent's context, instead of dumping it via Bash.
mksglu/context-mode
Routing rules for using context-mode MCP tools in Antigravity CLI: sandboxed code runs, file analysis, indexed search and web fetches that keep large output out of the conversation.
yvgude/lean-ctx
Review how the lean-ctx ctx MCP tools performed in the current session and file upstream issues for confirmed problems.
ourmem/omem
Shared memory that never forgets. An agent skill from ourmem/omem.
naw103/foremerge
Coordinate parallel coding agents with Foremerge's local Git-compatible CLI and MCP server.

Base Help fits situations like: any question about base (how to use it; what it can do for me; A base command errors; behaves unexpectedly.
Run `npx skills add ChristopherKahler/base --skill base-help -a claude-code`. Or copy the skill folder (claude/skills/base-help in ChristopherKahler/base) into .claude/skills/base-help in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ChristopherKahler/base --skill base-help -a codex`. Or copy the skill folder (claude/skills/base-help in ChristopherKahler/base) into .agents/skills/base-help in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ChristopherKahler/base --skill base-help -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/base-help, .gemini/skills/base-help, .github/skills/base-help and .opencode/skills/base-help in your project.
SKILL.md names no scripts, command-line tools or credentials: Base Help is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash(grep *), Bash(rg *), Bash(which base), Bash(base --version), Bash(base doctor), Bash(base help *), Bash(base --help), Bash(base commands list), Bash(base commands show *), Bash(base recall *), Bash(base decision search *), Bash(base handoff list), Bash(base fork list), Bash(base ast list), Bash(base ast query *), Bash(base context *), Bash(base relay board), Bash(base relay sessions), Bash(base relay tasks), Bash(base rule list *), Bash(base project list), Bash(base operator show), Bash(ls ~/.base-gbl/*).
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Base Help has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 2.6k tokens (SKILL.md is roughly 10k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 75k tokens, read only when the agent opens those files.
