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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00023 | $0.00294 |
| Opus 5 | $0.00012 | $0.00147 |
| Sonnet 5 | $0.00005 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
backfill 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 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.
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
Timelog Backfill
Process all existing Claude Code session transcripts and generate timelog entries for historical sessions.
Your task
-
Run the backfill script:
node ${CLAUDE_PLUGIN_ROOT}/scripts/backfill.mjs -
The script:
- Scans
~/.claude/sessions/for all JSONL transcripts - Extracts SessionStart, UserPromptSubmit, SessionEnd events
- Detects project names and ticket IDs
- Writes entries to
~/.claude/timelog/(or$CLAUDE_TIMELOG_DIR) - Outputs progress every 100 files
- Scans
-
Report the summary to the user (number of entries, date range, output location).
When to use this
- First-time setup: backfill all historical sessions
- After fixing ticket detection patterns: re-run to update logs
- After changing
CLAUDE_TIMELOG_DIR: regenerate logs in new location
Notes
- Safe to run multiple times (appends, doesn't duplicate)
- Filters out system-injected messages (not real user prompts)
- Uses the same config as live hooks (
~/.claude/timelog/config.json)
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.

backfill is a command published in the GitHub repository RemoteCTO/claude-code-timelog (7 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 23 tokens to every session and 294 once invoked, about $0.0001 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.
