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 | $0.00077 | $0.00282 |
| Opus 5 | $0.00039 | $0.00141 |
| Sonnet 5 | $0.00015 | $0.00056 |
| Haiku 4.5 | $0.00008 | $0.00028 |
Grade A, and why
context-modes 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 6d 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.
What it actually says
Context Modes
Set LACP_CONTEXT_MODE environment variable to activate a mode:
| Mode | Purpose |
|---|---|
tdd |
Strict RED-GREEN-REFACTOR — no code without a failing test |
debugging |
4-phase systematic root cause investigation |
sprint |
Pre-agreed completion criteria evaluated at stop |
verification |
Evidence-before-claims discipline |
brainstorm |
Design exploration — no code until design approved |
think |
Pause-and-reflect before every action chain |
orchestrate |
Decompose into subtasks before executing |
implementation |
Focused implementation partner |
review |
Code review mode |
thinking-partner |
Challenge assumptions, surface blind spots |
handoff-resume |
Continue from previous session handoff |
Each mode is a markdown file that gets injected as system context at session start.
What ships with it
11 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.

context-modes is a skill published in the GitHub repository 0xNyk/lacp (303 stars, last pushed 16d ago), licensed MIT. It adds 77 tokens to every session and 282 once invoked, about $0.0004 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.
