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

phren-discover 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 6d 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.

phren-discover - Phren health check

Audit your phren repo and tell you exactly what needs attention.

Scans your phren directory for missing files, stale content, skill gaps, and stuck task items. Outputs a concrete, prioritized action list.

Works standalone. Just needs a phren directory.

When to run

  • Weekly or monthly maintenance
  • When you feel like things are getting messy
  • Before starting a new project (to see what you've been neglecting)
  • When the user asks "what should I work on"

What to do

1. Find the phren directory

PHREN_DIR="${PHREN_DIR:-$HOME/.phren}"
ls "$PHREN_DIR" 2>/dev/null

If it doesn't exist:

"No phren directory found at ~/.phren. Run phren-init to set one up."

2. Scan all projects

For each project directory in $PHREN_DIR/*/ (skip global/, profiles/):

for dir in "$PHREN_DIR"/*/; do
  PROJECT=$(basename "$dir")
  [ "$PROJECT" = "global" ] || [ "$PROJECT" = "profiles" ] && continue

  [ -f "$dir/CLAUDE.md" ]    && echo "$PROJECT: has CLAUDE.md"    || echo "$PROJECT: MISSING CLAUDE.md"
  [ -f "$dir/summary.md" ]   && echo "$PROJECT: has summary.md"   || echo "$PROJECT: MISSING summary.md"
  [ -f "$dir/FINDINGS.md" ] && echo "$PROJECT: has FINDINGS.md" || echo "$PROJECT: MISSING FINDINGS.md"
  [ -f "$dir/tasks.md" ]   && echo "$PROJECT: has tasks.md"   || echo "$PROJECT: MISSING tasks.md"
done

3. Check staleness

For projects that are in a git-tracked phren, check when files were last modified:

cd "$PHREN_DIR"
for dir in */; do
  PROJECT=$(basename "$dir")
  [ "$PROJECT" = "global" ] || [ "$PROJECT" = "profiles" ] && continue

  if [ -f "$dir/FINDINGS.md" ]; then
    LAST_MODIFIED=$(git log -1 --format="%cr" -- "$dir/FINDINGS.md" 2>/dev/null || stat -c %Y "$dir/FINDINGS.md" 2>/dev/null || stat -f %m "$dir/FINDINGS.md" 2>/dev/null)
    echo "$PROJECT/FINDINGS.md: last updated $LAST_MODIFIED"
  fi

  if [ -f "$dir/CLAUDE.md" ]; then
    LAST_MODIFIED=$(git log -1 --format="%cr" -- "$dir/CLAUDE.md" 2>/dev/null || stat -c %Y "$dir/CLAUDE.md" 2>/dev/null || stat -f %m "$dir/CLAUDE.md" 2>/dev/null)
    echo "$PROJECT/CLAUDE.md: last updated $LAST_MODIFIED"
  fi
done

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.
