set-session-context

A session setup helper that names and colours a coding session based on its Git branch and related pull request.

In plain words
What is it for?
Starting or switching to a non-main branch, finding its pull request title, and assigning a session name and colour from the branch or pull-request context.
Why use it?
It makes multiple development sessions easier to recognise without requiring you to set their labels manually.

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

set-session-context 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 3d 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

Set Session Context

Automatically set session name and color based on the current git branch and PR.

Steps

  1. Detect branch:

    git symbolic-ref --short HEAD
    
    • If detached HEAD (command fails) → stop, do nothing
    • If main or master → stop, do nothing
  2. Look up PR title:

    gh pr view --json title --jq '.title'
    
  3. Determine session name:

    • If PR exists → use PR title
    • If no PR → humanize branch name: strip the conventional prefix and slash/hyphen separator, replace remaining hyphens with spaces
      • feat/add-widgetadd widget
      • fix-login-buglogin bug
  4. Run: /rename <session name>

  5. Determine color from the branch prefix (match ^(type)[/-]):

    Prefix Color
    feat blue
    fix red
    chore green
    docs cyan
    refactor yellow
    test purple
    ci orange
    build orange
    perf yellow
    style cyan
    (no match) blue
  6. Run: /color <color>

Behavior

  • Execute silently: do not announce, explain, or narrate what you are doing.
  • Do not ask for confirmation.
  • If gh is unavailable or fails, fall back to the humanized branch name.

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.
