What it does
Benchmark Methodology is an agent skill from jgravelle/jcodemunch-mcp. Rules for measuring or quoting any benchmark number in this repo. Load before running the bench tier, writing a delta into a PR or CHANGELOG, or touching anything under benchmarks/.
Its SKILL.md is about 440 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 Changelog and release notes 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 Changelog and release notes
- Tasks that involve MCP servers
Example prompts
- “Use the benchmark-methodology skill to rule for measuring or quoting any benchmark number in this repo”
- “/benchmark-methodology”
Requirements
- Python 3
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Never hand-type a number. Every figure comes from a run in THIS
- Per row, never per total (F-13): the total hid one cause behind
- Five mirrors move together (Practice 4): results.md,
- The reference is captured where the gate runs (F-13)
- Deterministic configuration is the bench tier itself: --offline,
- A refusal is not a zero: an absent value prints n/a.
- Floors live only in harness/thresholds.json; read one with
- benchmarks/schema_baseline.json is the only source for schema-token
What it can do on your machine
Read from SKILL.md and the folder at commit 526da05. 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
Benchmark Methodology loads about 438 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 191 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 191 words (~438 tokens).
“Authority: docs/harness/ARCHAEOLOGY.md (the benchmark rows), benchmarks/METHODOLOGY.md, benchmarks/REPRODUCING.md, CLAUDE.md Practice 4, docs/harness/FINDINGS.md F-10, F-13, F-17.”
