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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 70 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00094 | $0.01511 |
| Opus 5 | $0.00047 | $0.00756 |
| Sonnet 5 | $0.00019 | $0.00302 |
| Haiku 4.5 | $0.00009 | $0.00151 |
Grade A, and why
claude-session-manager 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 8d 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.

Claude Session Manager
Overview
Claude Code stores session transcripts as JSONL files under ~/.claude/projects/<project-key>/<session-id>.jsonl. Use the bundled manager to list candidates or export sessions into project-organized Markdown transcripts with a digest, a clean user/Claude conversation, and linked tool-call details.
Default output folder: ~/.claude/session-markdown. Tell the user before exporting there, and mention any custom output folder they requested.
Quick Start
Let the user's wording choose the mode when it is clear; otherwise ask them to choose before exporting:
- Full mode: export all matching sessions. Use this for archive, backup, broad search, or "convert all sessions" requests.
- Specific mode: list candidate sessions first, ask the user to pick one, then export only that session.
Run from any directory:
python3 /path/to/claude-session-manager/scripts/manage_claude_sessions.py
Equivalent explicit form:
python3 /path/to/claude-session-manager/scripts/manage_claude_sessions.py \
--source ~/.claude/projects \
--output ~/.claude/session-markdown
Useful options:
--mode full: export all matching sessions. This is the default.--mode specific --list-candidates: print a numbered candidate table and do not export.--mode specific --pick N: export the Nth candidate from the same filtered candidate list.--project <text>: only export project folders whose key contains this text.--session <text>: only export sessions whose id or filename contains this text.--since YYYY-MM-DD: only export sessions modified on or after this date.--limit N: export the N most recently modified matching sessions.--include-tool-details-inline: embed full tool inputs/results in the main session Markdown. By default, the main transcript keeps compact collapsible tool summaries and links full payloads through the sidecar file.
Specific Mode Candidate Flow
Use this flow when the user wants one session, is unsure which session they need, or asks to inspect recent sessions before converting.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

claude-session-manager is a skill published in the GitHub repository sugarforever/01coder-agent-skills (134 stars, last pushed 2mo ago), licensed MIT. It adds 94 tokens to every session and 1,511 once invoked, about $0.0005 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 2026-08-30.
