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 | $0.01190 |
| Opus 5.5 | $0.00014 | $0.00476 |
| Sonnet 5.5 | $0.00007 | $0.00238 |
| Haiku 4.5 | $0.00004 | $0.00119 |
Grade A, and why
sdk-install 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LaunchDarkly SDK Install (onboarding)
Installs and initializes the right LaunchDarkly SDK for the user’s project by following three nested skills in order. Do not skip ahead to feature flags here—the parent LaunchDarkly onboarding continues with Step 6: First feature flag using Create first feature flag.
Prerequisites
- Project context from parent Step 1: Explore the Project (reuse it; only re-run deep detection if something is unclear)
- SDK key / client-side ID / mobile key: Needed when you reach Apply code changes (env wiring). Do not ask the user for these during detect or plan solely because you opened this skill—follow parent onboarding: account status is inferred via MCP OAuth (Step 4) or surfaced at D7 in apply; key material is collected at apply (see parent Prerequisites).
Key types (summary)
| SDK Type | Variable (logical) | Source in LaunchDarkly |
|---|---|---|
| Server-side | LAUNCHDARKLY_SDK_KEY |
Environments → SDK key |
| Client-side | Client-side ID (bundler-prefixed env names) | Environments → Client-side ID |
| Mobile | LAUNCHDARKLY_MOBILE_KEY |
Environments → Mobile key |
Never hardcode keys. Full env rules, consent, and bundler tables: Apply code changes Step 2.
Workflow — run these nested skills in order
Execute all three unless the detect decision tree short-circuits (e.g. skip to apply only). Each nested skill may contain decision points — some blocking (marked D<N> -- BLOCKING, where you must call your structured question tool and wait for the user's response before continuing) and some non-blocking (where you present information and continue unless the user objects). Do NOT batch tool calls across blocking boundaries.
| Order | Nested skill | Role |
|---|---|---|
| 1 | Detect repository stack | Language, package manager, monorepo target, entrypoint, existing LD usage |
| 2 | Generate integration plan | SDK choice, files to change, env plan -- presented to user (non-blocking; see plan SKILL.md D6) |
| 3 | Apply code changes | Install package(s), .env / secrets with consent, init code, compile check (both tracks when dual-SDK plan) |
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.
- 1mo ago First seen · 73 lines · 36 tokens per session scan A 625d0400f6c3
sdk-install is a skill published in the GitHub repository Bilal140202/the-lord-of-the-skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 1,190 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 2026-09-06.

tool-calling-tutor
Use when a tool-calling agent does not call a tool, sends wrong arguments, loops without stopping, or needs a function schema. Guides a four-branch diagnosis and five-step schema repair. Do not use for framework-specific, MCP-server, or production-observability questions.
ainb-fleet:daemons
Runtime-health view of the four fleet daemons — phone bridge, notifyd, ATC, and the fleet auto-continue daemon — in one table. Each row reports state (running / stopped / unknown), pid, uptime, last activity, error count, and a HEALTH reason that distinguishes a clean stop from a crash (stale heartbeat) or a…
ainb-fleet:atc
ATC (Air Traffic Control) — the single operator-visible fleet supervisor, in exactly one mode: lite (no LLM: deterministic scan, known-transient retry policy, safety caps, evidence) or full (the persistent orchestrating brain). Full mode is a plain ainb session (Claude or Codex) running a generated policy, woken on a…
ainb-fleet:fleet-needs
Workflow-backed Jarvis control panel. Runs the deterministic hangar workflow with verb=needs (discover → enrich → prioritize), renders the Jarvis HUD from its render-ready cards, fires AskUserQuestion per blocked session, and routes each answer back via tmux send-keys (broker fallback only). Requires the workflow gate…
