boundary-handoff

boundary-handoff is a skill for Claude Code, Codex from Cody-W-Tucker/Cognitive-Assistant. It costs 67 tokens per session (2,055 once invoked), scanned A, original, Apache-2.0.

A guide for handing work from one person or stage to another. It helps match the amount of structure and proof to what the next person must do.

In plain words
What is it for?
Use it for codebase exploration, debugging, architecture or configuration work, design reviews, agent workflows, and deliverables prepared for another operator.
Why use it?
It prevents recommendations or instructions from getting ahead of what was actually inspected or verified. It clarifies when to keep exploring and when to commit.

Token cost

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.

Security

Grade A, and why

boundary-handoff 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 11d 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.

Boundary Handoff

When To Use

Load this when a task is about to change hands or change stage, and the right response depends on reading the boundary correctly:

  • A rough draft is becoming an artifact someone else will use to act
  • You are tempted to prescribe before inspecting the real thing
  • A recommendation might outrun what was actually verified
  • You are unsure whether to keep exploring or commit to a move
  • You are about to add structure, layers, or process and aren't sure they earn their place
  • Technical, revision-heavy, or execution-facing work: codebase exploration, architecture/config, debugging, design review, prompt/system work, agent workflows, lead enrichment, sales rewriting
  • Preparing a spec or deliverable for a downstream agent or non-technical operator

Do Not Use

  • Simple factual lookups, quick troubleshooting, one-off how-to: answer directly — no decomposition, no imposed format, no tightening loop
  • Open-ended philosophical or phenomenological exploration: approximation permitted; don't force operational artifact standards without a physical artifact or bounded business parameter
  • Initial scope still unnamed (object/operator/acceptance missing) — use scope-framing first
  • Mechanism is simply overbuilt and needs collapse — complexity-reduction
  • Response is drifting mid-work (blind patch, fluency without ground) — failure-recovery

Core Reading: Speed Is Bought, Not Compromised

Locate rigor; do not average it. Speed and rigor resolve by which side of the line you are on, not by compromise.

Side Examples Standard
Reversible / discovery scout, probe, retrieve, test, rough draft, "for now" experiment Fast, broad enough to orient, rough OK
Commitment / handoff synthesis, recommendation, config that persists, sales copy, agent spec, anything operated/sold/built upon Slow down, tighten, claims must hold, clarity mandatory

Buy safe speed by spending cheaply on upfront discovery so the expensive moment is already de-risked.

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.

boundary-handoff is a skill published in the GitHub repository Cody-W-Tucker/Cognitive-Assistant (11 stars, last pushed 24d ago), licensed Apache-2.0. It adds 67 tokens to every session and 2,055 once invoked, about $0.0003 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.
