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: 4 findings, up to high
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 →
- high Privilege Escalation · line 41 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

- medium Excessive Agency · line 112 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 | $0.00055 | $0.01555 |
| Opus 5.5 | $0.00022 | $0.00622 |
| Sonnet 5.5 | $0.00011 | $0.00311 |
| Haiku 4.5 | $0.00006 | $0.00155 |
Grade A, and why
handoff scanned grade A with 1 finding 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.

Handoff -- Session Context Transfer
When to use
- You are about to hit context limits and need to preserve task state
- A task needs to continue in a fresh session (yours or another agent's)
- Inter-agent delegation of a complex, multi-step task
- User explicitly says
/handoffor asks to "save context for later" - Before a
/checkpointwhen the task is too complex for 3-5 bullet points
Arguments
| Argument | Required | Description |
|---|---|---|
purpose |
YES | What the next session should do with this context |
target |
no | Agent name (e.g. target=dev2) -- sends via inter-agent message instead of writing file |
output |
no | File path override (default: project root HANDOFF.md) |
Examples:
/handoff purpose="Continue the Pipedrive connector PR review and address CI failures"/handoff purpose="Finish the scheduler forceSend implementation" target=dev2/handoff purpose="Debug the auth redirect loop" output=/tmp/handoff-auth.md
Procedure
1. Gather context
Collect data from these sources (skip any that return empty):
# Active kanban cards (assigned to current agent or recently touched).
# Via the dashboard API, NOT the sqlite3 CLI: sqlite3 (and jq) are absent on a
# stock Linux install -- measured on two live hosts 2026-08-04, where the CLI
# call died with exit 127 while python3 was present on both.

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.

handoff is a skill published in the GitHub repository Szotasz/marveen (123 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 1,555 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

commonly
You are a member of a Commonly workspace — a shared space where humans and AI agents from any origin collaborate in pods (chat rooms with memory). Use this whenever you are connected to Commonly via the commonly MCP tools: to read what's happening, post, remember things across sessions, react, DM other agents, and…
memory
Use this skill when Pioneer should proactively use durable memory or recalled context: decide whether memory can improve a turn, answer from remembered user/project facts, request memory tools, search/list/get stored memories, save durable preferences or project decisions, forget memories, audit or clean up memory, or…
family-knowledge
Family knowledge base for recording and retrieving household facts (members, allergies, dietary rules, doctors, schedules, house rules, pets, important dates).
user-memory
Remember and recall durable facts about the current user across sessions. Stores preferences, ongoing context, and things the user asked you to remember — scoped to each individual user.
openopc
An organisation runtime for turning an AI assistant into a group of role-based workers. It creates an organisation structure, breaks work into dependent tasks that can run in parallel, tracks approvals and handoffs, and stores organisational memory.
openakashic
Persistent memory for AI agents across sessions. Search what others figured out, write what you learn, publish what deserves a wider audience.
