/reflect - manual reflection promotion

Escape hatch for the automated reflection pipeline. Stop hook subagent extraction (reflection-extract.sh) normally writes per-session reflections automatically. When that pipeline fails (subagent timeout, API error, build issue), /reflect lets you produce the same artifact manually before the session ends.

This is not the primary path. The Stop hook is. Use this skill in any of these cases.

• The latest knowledge/reflection/<session_id>.md is a placeholder: true file (auto-extraction returned empty) and you have meaningful reflection to capture.
• You want to override or edit the auto-extracted content before the next session reads it.
• You suspect the Stop hook is broken on this machine and want to verify the knowledge store stays current.

Setup: Resolve paths

Run once at the top of the skill.

KDIR="${REFLECT_KNOWLEDGE_DIR:-${CLAUDE_PROJECT_DIR}/.claude/knowledge}"
SID="${CLAUDE_SESSION_ID:?session id required}"
MD="$KDIR/reflection/$SID.md"
INDEX="$KDIR/reflection-index.jsonl"

If $KDIR does not exist, advise the user to run a session under the Stop hook at least once (the directory is created on first auto-extraction) or set REFLECT_KNOWLEDGE_DIR explicitly.

Phase 1: Read the current state

Print the following to the user, in this order.

1. Does $MD exist? If yes, show it (frontmatter + body).
2. Is it a placeholder (placeholder: true)? Flag it.
3. Latest 3 entries from $INDEX (so the user sees the local history).

Phase 2: Compose

Generate a fresh reflection across the 3 categories. Use the same shape as agents/reflection-extractor.md and reuse its guidance (realization / judgment / counterfactual). Keep the body under 300 words total. Use this output frontmatter.

---
session_id: <SID>
confidence: confirmed   # always "confirmed" for /reflect — user-attested
categories: [...]
word_count: <int>
created_at: <ISO8601 UTC>
promoted_via: reflect-skill
---

The promoted_via: reflect-skill field marks manual promotions so audits can distinguish them from auto-extracted reflections.

Phase 3: Confirm

Show the user the composed reflection in a fenced block, then ask "Promote this to $MD? (yes / edit / cancel)".

• yes → Phase 4
• edit → ask what to change, regenerate, return to Phase 3
• cancel → exit without writing

Phase 4: Write and index

# Atomic write: stage to a temp file, then move.
TMP="$(mktemp "$KDIR/reflection/.$SID.XXXXXX")"
cat > "$TMP" <<EOF
<composed reflection>
EOF
mv "$TMP" "$MD"

# Index: append if this session has no prior entry, otherwise skip
# (append-only contract; duplicates are tolerated but noisy).
if ! grep -Fq "\"session_id\":\"$SID\"" "$INDEX" 2>/dev/null; then
  printf '{"session_id":"%s","reflection_file":"%s","created_at":"%s","promoted_via":"reflect-skill"}\n' \
    "$SID" "$MD" "$(date -u +'%Y-%m-%dT%H:%M:%SZ')" >> "$INDEX"
fi

echo "Promoted to $MD"

Constraints

• Never modify CLAUDE.md, MEMORY.md, rules/, agents/, skills/, or any file referenced by paths: frontmatter. Same auto-loaded-path immutability rule as the Stop hook. Violations invalidate the prompt cache for every following session.
• Never read transcripts outside the current session.
• Never call claude --bare recursively. This skill runs in the main session, not in a subagent.

When not to use this

• The Stop hook is working and the latest reflection is confidence: confirmed (not placeholder). Re-running /reflect would overwrite a higher-quality extraction.
• You want to edit a reflection from an old session. That requires manual edit of $KDIR/reflection/<old-sid>.md, not this skill.
• You want to delete entries. The index is append-only by contract; deletion is a separate operation outside this skill.
