syft-storyline-backfill

syft-storyline-backfill is a skill for Claude Code, Codex from Solatrader/syft-news-skills. It costs 89 tokens per session (1,466 once invoked), scanned A, original, Apache-2.0.

A workflow for extending a storyline timeline with search results from Syft, a search service, over an earlier or missing time period. A storyline tree is a structured record of related events and developments.

In plain words
What is it for?
Use it to backfill one branch, one main storyline, or the whole storyline tree. It can also derive search-keyword strategies and produce updated Markdown, HTML, or JSON timeline files.
Why use it?
It helps recover older events or fill gaps in an existing storyline without writing local Python scripts, while keeping working notes separate from final timeline files.

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

syft-storyline-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 12d 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.

Syft Storyline Backfill

Use this skill after a storyline tree already exists and the user wants one branch, one trunk, or the full tree extended with older or missing events.

Inputs

Prefer to have:

  • an existing storyline tree markdown file
  • optional html or notes version of the same tree
  • profiles/following_topics.md
  • profiles/profile_summary.md
  • optional guidance rules

What this skill produces

Create:

  • storylines/storyline_backfill_<date>.md
  • optionally an updated storyline tree markdown file
  • optionally an updated storyline tree html file
  • optionally an updated storyline tree json file
  • optionally storylines/backfill_keyword_strategy_<date>.md

Important:

  • storyline_backfill_<date>.md is a working-facing explanation artifact
  • the updated storyline tree files are user-facing final artifacts

Do not confuse the two. Working-note language is acceptable in the backfill memo. It is not acceptable in the final tree outputs.

Workflow

  1. Choose the target. The user may specify:

    • one branch
    • one trunk
    • all branches
  2. Restate the target meaning in one sentence before searching. Do not search from labels alone. If the branch is a hobby or travel line, restate the branch logic precisely.

    Examples:

    • not just Fate

    • but Fate official merch / collab / event cadence

    • not just Japanese onsen

    • but high-quality scenic ryokan / seasonal opening / local cuisine line

  3. Use the retrieval ladder. Before broad search, check whether the branch maps to a followed topic id. Default order:

    1. existing known events
    2. topic top via syft top --topic-id <TOPIC_ID> --days <N> --limit 20 --rich
    3. targeted syft search

    Topic top should be the normal second step because it often returns higher-quality branch-local material than free-text search. Start with limit 20. In most branches, the first 20 topic-local items are enough to show whether the branch can be filled cleanly. Only widen the limit if the branch remains obviously thin after triage.

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.
