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 | $0.00036 | $0.00706 |
| Opus 5.5 | $0.00014 | $0.00282 |
| Sonnet 5.5 | $0.00007 | $0.00141 |
| Haiku 4.5 | $0.00004 | $0.00071 |
Grade A, and why
session-done 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 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.
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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session Done
Purpose
Capture the outcome, evidence, unresolved work, and next action without making session completion a cleanup or memory-write command.
When to use
- The user asks for a session handoff, continuation summary, or
/done. - The user requests a durable Markdown handoff, including a note in a PKM/Obsidian folder.
Workflow
- Use the current task's evidence. Record completed work, validation and its limits, blockers, and the next owner/action. Do not scan unrelated sessions or copy credentials, private logs, or raw transcripts.
- Include known session, branch, commit/PR, and retained-checkout identities when relevant. Mark unknown facts as unknown. Completion does not terminate sessions, remove worktrees, release owners, or rerun cleanup.
- Return the handoff in chat by default. For deterministic Markdown, run
python3 scripts/session-done --summary "..." --state "..." --follow-ups "..."; it writes only stdout. - If the user explicitly requested retention, use one named destination with
--output <new-path>. The parent must already exist; existing files and symlinks are refused. A PKM/Obsidian folder can be that destination, without a second copy or sync service. - Report the created path or exact failure. A failed write is not saved evidence. Preserve existing notes and recovery material; do not retry under new filenames automatically.
- Update memory only when the user directly requests it, through the environment's existing memory workflow. This writer never appends to shared memory or edits agent-managed memory files. Report that separate action's outcome.
Inputs
- At least one content flag:
--summary,--decisions,--questions,--follow-ups,--state,--reflection, or--flashcards. - Optional
--session-idand--branch: verified values; both default tounknown. - Optional
--output: the explicitly requested new Markdown file. No environment variable enables retention, copying, or memory writes.
Outputs
What ships with it
3 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.

session-done is a skill published in the GitHub repository vincentkoc/dotskills (109 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 706 once invoked, about $0.0001 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 2026-09-15.
