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 | $0.00015 | $0.01303 |
| Opus 5 | $0.00008 | $0.00651 |
| Sonnet 5 | $0.00003 | $0.00261 |
| Haiku 4.5 | $0.00002 | $0.00130 |
Grade A, and why
close-session 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.

Close Session
Save progress, update memory, regenerate navigation, and ensure system integrity.
Purpose
The close-session skill is the most critical system skill. It ensures nothing is ever lost by:
- Reading and updating build progress from steps.md checkboxes
- Validating workspace-map.md accuracy (auto-detect mismatches)
- Updating memory with decisions and patterns
- Cleaning temporary files from root folder
- Creating historical session reports
- Displaying comprehensive summary
CRITICAL: This skill is AUTO-TRIGGERED by all other skills and builds (not user-dependent!).
Execution Sequence
- Initialize TodoWrite with all 10 steps (MANDATORY - prevents skipped steps)
- Load workflow.md
- Execute steps 1-10 sequentially
- Mark each step complete in TodoWrite as you finish it
Critical Rules
- TodoWrite is MANDATORY: Initialize at start with all 10 steps - prevents forgetting critical steps
- PLANNING phase builds: Skip task completion (Step 2/2.5)
- IN_PROGRESS phase builds: Auto-complete if execution signals detected
- Session reports: Create in 01-memory/session-reports/
- Summary display: ≤5 lines per orchestrator.md rule
Key Features
Automatic & Interactive Task Completion
Smart task completion with automatic detection:
- Automatic Bulk Complete: If build work completed this session, auto-marks all tasks
- Manual Bulk Option: If auto-detect missed it, offers bulk-complete during review
- Interactive Review: Shows first 10 unchecked tasks for manual selection
- User selects by number ("1, 3, 5"), "all", "bulk complete", or "none"
- Updates tasks.md automatically (via Edit tool or bulk-complete script)
- Recalculates progress after any changes
Temp File Cleanup
Interactive cleanup with user choices:
- Scans root folder for temp files
- Asks what to do with each: keep, delete, or skip
- Moves preserved files to build outputs/
- Reports cleanup summary
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.

close-session is a skill published in the GitHub repository DorianSchlede/nexus-template (8 stars, last pushed 7mo ago), licensed MIT. It adds 15 tokens to every session and 1,303 once invoked, about $0.0001 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 2026-09-03.
