The criterion numbers of STANDARD.md, so an acceptance criterion can be mapped to one.

What it does

Standard Axes is an agent skill from jgravelle/jcodemunch-mcp. The criterion numbers of STANDARD.md, so an acceptance criterion can be mapped to one. Load in /feature step 2.

Its SKILL.md is about 280 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 Agent Workflows, covering Accessibility and MCP servers. It works with Model Context Protocol. The repository describes itself as: Cut AI token costs 95%+ on code exploration. The leading MCP server for precise, symbol-level GitHub code retrieval via tree-sitter AST. Works with Claude Code, Cursor & any MCP…

When your agent uses it

  • Tasks that involve Accessibility
  • Tasks that involve MCP servers

Example prompts

  • “/standard-axes”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 970c457. 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

    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

Standard Axes loads about 278 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 147 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~278

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 147 words (~278 tokens).

“Authority: docs/standard/STANDARD.md. Read the criterion you map to; this list is only its index.”
