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 5.1 | $0.00097 | $0.02094 |
| Opus 5.5 | $0.00039 | $0.00838 |
| Sonnet 5.5 | $0.00019 | $0.00419 |
| Haiku 4.5 | $0.00010 | $0.00209 |
Grade D, and why
salvage-session-archives scanned grade D with 2 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 1mo 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.

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.
- Output instructions: append (via Edit with a unique anchor at end of file, NOT Write) a section titled exactly `## Salvaged from session archives`. Organize by topic, not by session. Tight bullets. Plain language: no e Recursive force deletehighDestructive command

Ask the user to confirm before deleting. On confirmation, `rm -rf` each leftover folder identified in step 2. After deletion, run a quick `find` to confirm only the canonical project folder remains. Never delete the cano How it starts
The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Salvage session archives for a project
Goal: recover any durable knowledge that lives in old session .jsonl transcripts but never made it into the project's CLAUDE.md, then clean up.
The Claude Code harness writes transcripts into auto-named "leftover folders" with dashed paths (e.g. ~/.claude/projects/-Users-<username>--claude-projects-<ProjectName>/). Sessions that ended cleanly already distilled their content via an end-of-session save, but premature exits, subagent runs, and quietly-discovered gotchas often leave salvageable material behind.
When to run
- User asks to salvage / collect / extract / mine session archives or leftover folders.
- End-of-quarter cleanup pass across multiple projects.
Steps
1. Identify the project from the current working directory
Do NOT ask the user which project to work on. Derive <project_name> from the current working directory (pwd). Handle these cases:
pwdis~/.claude/projects/<ProjectName>/→ use<ProjectName>directly. This is the canonical project directory.pwdis the project's source repo (anywhere on disk) or a subdir of it → use the repo directory's basename as<ProjectName>. The canonical project directory is~/.claude/projects/<ProjectName>/.pwdis a dash-prefixed leftover folder like~/.claude/projects/-Users-<username>--claude-projects-<ProjectName>/→ use<ProjectName>(the trailing segment after the last-).pwdis~/.claudeitself or any other location that doesn't clearly map to a project → only in this case, list~/.claude/projects/and ask the user which project to target (show the 3-4 most recently-touched vials -lt).
State the inferred project name in one sentence before continuing, so the user can redirect if needed. Then proceed without waiting for confirmation.
2. Find every leftover folder for that project
Run find ~/.claude -maxdepth 3 -type d -iname "*<project_name>*" and inspect the results. Real leftover folders are the dash-prefixed ones (Claude Code encodes each session's working-directory path into the folder name, replacing every / with -, so a -Users-<username>-... prefix is just your $HOME dash-encoded). For example:
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.

salvage-session-archives is a skill published in the GitHub repository eranw2000/claude-maintenance-skills (8 stars, last pushed 4d ago), licensed MIT. It adds 97 tokens to every session and 2,094 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it D with 2 findings (asks the agent to reveal its instructions, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
