Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 91 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 604 The whole file, excluding the scripts and references it only reads on demand.

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

github-context-loader scanned grade A with 1 finding 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 2d 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.

What it actually says

GitHub Context Loader

Pulls latest CLAUDE.md and skill updates from Prash1407's GitHub repos into the active session context.


Repos to sync (in order)

Repo What to pull Load into
Prash1407/kleinanzeigen-reader CLAUDE.md, SKILL.md Active context

Add more repos here as the Brain OS ecosystem grows.


Step 1 — Pull CLAUDE.md from each repo

curl -s \
  -H "Accept: application/vnd.github.v3.raw" \
  "https://raw.githubusercontent.com/Prash1407/kleinanzeigen-reader/main/CLAUDE.md"

Read the output and treat it as active session context.


Step 2 — Check for recent commits

curl -s \
  "https://api.github.com/repos/Prash1407/kleinanzeigen-reader/commits?per_page=3" \
  | python3 -c "
import sys, json
commits = json.load(sys.stdin)
for c in commits:
    print(c['commit']['author']['date'][:10], '---', c['commit']['message'][:60])
"

Summarize any changes since the last session in one sentence.


Step 3 — Pull updated scripts if needed

If commits touch scripts/ or references/, fetch updated files:

curl -s -H "Accept: application/vnd.github.v3.raw" \
  "https://raw.githubusercontent.com/Prash1407/kleinanzeigen-reader/main/scripts/extract.py" \
  > /tmp/kl_extract.py

curl -s -H "Accept: application/vnd.github.v3.raw" \
  "https://raw.githubusercontent.com/Prash1407/kleinanzeigen-reader/main/scripts/compare.py" \
  > /tmp/kl_compare.py

Use /tmp/kl_extract.py and /tmp/kl_compare.py for the rest of the session.


Output after sync

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.
