MCPPythonDemo: Skill for Claude Code

.squad/skills/branch-archaeology/SKILL.md

branch-archaeology is a skill for Claude Code, Codex from alonf/MCPPythonDemo. It costs 19 tokens per session (433 once invoked), scanned A, original, MIT.

A method for reconstructing a project's teaching progression when milestone branches in Git do not form a reliable sequence. A branch is a named line of code history.

In plain words
What is it for?
It is for comparing milestone branches, checking their actual changes, and documenting differences between the intended roadmap and the code.
Why use it?
It prevents branch names or commit ancestry from giving a misleading picture of how the project evolved.

Written for no agent in particular: nothing here depends on one.

This is alonf/MCPPythonDemo's own configuration. It tells Claude Code and Codex how to work on MCPPythonDemo itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything MCPPythonDemo configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

branch-archaeology scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Context

Use this when a repository has milestone-named branches but branch names or tip commits are not trustworthy indicators of the actual teaching progression.

Patterns

  • Start with the roadmap or lecture artifact (docs/MCPDemoRoadmap.md here) to learn the intended milestones.
  • Verify each milestone by diffing the branch against the previous milestone and by reading the exact server/client files touched.
  • Check branch containment (git branch --contains <sha>) before assuming milestones are linear ancestors.
  • Prefer behavior over labels: summarize what tools, resources, prompts, transports, and safety mechanisms actually changed.
  • Note documentation drift explicitly when README text lags behind the code.

Examples

  • In alonf/MCPDemo, milestone-1 through milestone-7 are best interpreted via roadmap plus file diffs; only milestone-7 flows directly into master.
  • master differs from milestone-7 mostly by docs polish (docs/Milestone-*.gif) and minor solution metadata, so the runtime architecture is effectively the milestone-7 architecture.

Anti-Patterns

  • Assuming milestone branches form a strict ancestry chain without checking.
  • Using only branch tip commit messages to infer milestone content.
  • Treating README prose as authoritative when branch code and roadmap disagree.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
