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 | $0.00042 | $0.04057 |
| Opus 5.5 | $0.00017 | $0.01623 |
| Sonnet 5.5 | $0.00008 | $0.00811 |
| Haiku 4.5 | $0.00004 | $0.00406 |
Grade A, and why
first-flag scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
**REST / curl auth:** Use `$LAUNCHDARKLY_ACCESS_TOKEN` as the `Authorization` header value (LaunchDarkly uses the raw token, no `Bearer` prefix). The shell expands the variable but doesn't log it. How it starts
The opening of the file, as written. The whole thing — 383 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create first feature flag
The SDK is connected. Now help the user create their first feature flag and see it work end-to-end.
This skill is nested under LaunchDarkly onboarding; the parent Step 6 is first flag. Prior: Apply code changes.
Optional -- Flag Create skill already installed: If the launchdarkly-flag-create skill from github.com/launchdarkly/ai-tooling is available in the session (install with npx skills add launchdarkly/ai-tooling --skill launchdarkly-flag-create -y --agent <agent>), you may use it for creating the flag and choosing evaluation code that matches the repo. You must still complete default off -> verify OFF -> toggle on -> verify ON (Steps 3-5 below). Do not require that skill: this page stays the full fallback when it is missing or MCP-only flows conflict with the user's setup.
Security: Credential handling
Never substitute literal token values into commands. Use environment variable references instead:
- Shell commands:
$LAUNCHDARKLY_ACCESS_TOKEN(expanded by the shell, not visible inpsoutput) - Set the variable in your session:
export LAUNCHDARKLY_ACCESS_TOKEN=<your-token>
This prevents tokens from appearing in process lists, shell history, and screen recordings.
Step 0: Consult SDK flag-key guidance
Before creating the flag or wiring evaluation code, check the Flag key behavior by SDK table below. Some SDKs transform flag keys before exposing them in application code (e.g. the React SDK camelCases kebab-case keys). The flag key you create in LaunchDarkly, the SDK/framework configuration, and the key you reference in code must all align.
- If the SDK transforms keys (e.g. React
useFlags()camelCasesmy-first-flag→myFirstFlag): generate evaluation code using the transformed key. The flag key in LaunchDarkly stays as-is (kebab-case is conventional). - If the SDK preserves keys as-is (most server-side SDKs): use the exact LaunchDarkly flag key string in code.
- If the SDK supports both modes (e.g. React allows disabling camelCase via provider options): decide which mode the project uses (check existing code or provider config), then generate code that matches.
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.

first-flag is a skill published in the GitHub repository Bilal140202/the-lord-of-the-skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 4,057 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 2026-09-06.

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.

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).
