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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.00849 |
| Opus 5.5 | $0.00023 | $0.00340 |
| Sonnet 5.5 | $0.00012 | $0.00170 |
| Haiku 4.5 | $0.00006 | $0.00085 |
Grade A, and why
story-arcs 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 2mo 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.

How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Story Arcs
Manage the developing-story-arcs file that feeds the feed-brief arc-tagging enrichment.
Usage
/story-arcs add "<name>" [--started <YYYY-MM-DD>] [--watch "<keywords>"] [--context "<text>"]
/story-arcs resolve "<name>" [--reason "<resolution note>"]
/story-arcs list
Steps
1. Find the active arcs file
Glob .claude-code-hermit/compiled/story-arcs-*.md. Sort by filename date suffix descending (newest first). Read the most
recent. If none exists, create .claude-code-hermit/compiled/story-arcs-<today>.md with the standard template
(frontmatter + ## Active + ## Recently Resolved sections).
2. Execute subcommand
add
Parse: name (required), --started (default: today, prefixed with ~), --watch (optional keyword list), --context (optional description).
- Check
## Active— if an arc with the same name already exists (case-insensitive), say so and stop. - Append a new arc block at the end of
## Active:**<name>** (started: ~<YYYY-MM-DD>) <context text, or "Newly surfaced — add context as it develops."> Watch: <watch keywords separated by semicolons, or "TBD">. - Write the file in-place. Reply:
Arc added: **<name>**. Update the Watch clause with /story-arcs if needed.
resolve
Parse: name (required, case-insensitive substring match), --reason (optional).
- Find the arc block in
## Active. If not found, list close matches and stop. - Remove the full arc block (the
**Name** (started:...)line + context line + Watch line). - Insert a one-line entry at the top of
## Recently Resolved:**<name>** — <reason, or "resolved">. <today's date> - Write the file in-place. Reply:
Arc resolved: **<name>**. It will no longer be matched in future briefs.
list
- Display all arcs under
## Activeas a compact table: Name, start date, Watch keywords. - Show the count of
## Recently Resolvedentries. - If
## Activeis empty, say "No active arcs."
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.

story-arcs is a skill published in the GitHub repository gtapps/claude-code-hermit (83 stars, last pushed 3d ago), licensed MIT. It adds 58 tokens to every session and 849 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
