propose-objection

A command for proposing a challenge to an argument or decision and placing it in a fractal tree, a branching structure of related objections. With no text, it analyzes the current objection and suggests a more specific one.

In plain words
What is it for?
Use it to add an objection manually or discover the next sub-objection during an analysis.
Why use it?
It turns vague disagreement into a structured set of challenges that can be examined one level at a time.

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

propose-objection 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 460 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/fractal:propose-objection

Human gates

Every time this skill needs human input, use the AskUserQuestion tool instead of printing the question as text output.

Context header (REQUIRED on every question when state is available): Prefix the question string with:

📍 | 🎯 <active_predicate (max 80 chars)>

Variables come from the pre-loaded State section. If state is not yet loaded (e.g., early steps before tree detection), omit the header.

IMPORTANT: The header must be plain text. No markdown formatting (no **, ##, *, etc.) in the question string. Emojis are fine as visual anchors.

Input: $ARGUMENTS — challenge/objection text in natural language, or empty to enter analyze mode.


Step 1: Route on arguments

If $ARGUMENTS IS provided

Use it directly as the challenge text. Skip to Step 2 (Reframe).


If $ARGUMENTS is empty — ANALYZE MODE

Enter analyze mode. This evaluates the active predicate and proposes the next sub-objection (i.e., the reason why the challenge still holds).

Step A: Detect tree
REPO_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || pwd)
FRACTAL_DIR="$REPO_ROOT/.fractal"
TREES=()
for d in "$FRACTAL_DIR"/*/; do [ -f "${d}root.md" ] && TREES+=("$d"); done
if [ "${#TREES[@]}" -eq 1 ]; then
  TREE_DIR="${TREES[0]}"
elif [ "${#TREES[@]}" -gt 1 ]; then
  echo "multiple_trees: true"
  for t in "${TREES[@]}"; do echo "tree: $(basename "$t")"; done
fi

If no tree found: STOP with message "Nenhuma árvore fractal encontrada. Execute /fractal:init-objection primeiro."

If multiple trees found: ask the user which tree to work with via AskUserQuestion.

ROOT_MD="${TREE_DIR}root.md"
ACTIVE_NODE=$(grep "^active_node:" "$ROOT_MD" | sed 's/^active_node:[[:space:]]*//' | tr -d '"')
FRACTAL_SCRIPTS=$(ls -d ~/.claude/plugins/cache/fractal/fractal/*/scripts 2>/dev/null | tail -1)
[ -z "$FRACTAL_SCRIPTS" ] && FRACTAL_SCRIPTS="$REPO_ROOT/scripts"
bash "$FRACTAL_SCRIPTS/fractal-state.sh"

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.

propose-objection is a command published in the GitHub repository rmolines/fractal-loop (13 stars, last pushed 5mo ago), licensed MIT. It adds 46 tokens to every session and 4,134 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
