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 | $0.00073 | $0.01742 |
| Opus 5.5 | $0.00029 | $0.00697 |
| Sonnet 5.5 | $0.00015 | $0.00348 |
| Haiku 4.5 | $0.00007 | $0.00174 |
Grade B, and why
posthog scanned grade B with 2 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**Do NOT suggest editing `~/.claude/settings.local.json` manually.** The `teleport-setup add-key` command handles it with backup, validation, and masked input. Stop execution until the user has run the command and restar Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PostHog
Operates PostHog via REST API — event analytics, HogQL queries, feature flags, experiments, session recording metadata, insights, persons. Supports US cloud, EU cloud, and self-hosted. No MCP server required.
Usage
- Use for: HogQL queries ("how many
$pageviewlast 7d?"), flag inspect/toggle, last-N events for a user, experiment results. - Skip for: Debugging client-side tracking, raw event ingestion (use an SDK), concept questions, raw replay JSON export (UI-only).
Credentials check
[ -n "${POSTHOG_PERSONAL_API_KEY:-$POSTHOG_API_KEY}" ] && echo "POSTHOG_API_KEY: PRESENT" || echo "POSTHOG_API_KEY: MISSING"
Never echo the variable directly.
If MISSING, respond to the user with EXACTLY this message (do NOT paraphrase, do NOT suggest manual JSON edits):
I need your posthog credential. Run this in another terminal — it'll open the signup page, validate format, and save it safely with masked input:
teleport-setup add-key posthogThen restart Claude Code (
/exit, thenclaude) and ask me again.
Do NOT suggest editing ~/.claude/settings.local.json manually. The teleport-setup add-key command handles it with backup, validation, and masked input. Stop execution until the user has run the command and restarted.
API
- Base URL varies: US
https://us.posthog.com, EUhttps://eu.posthog.com, self-hostedhttps://{your-host}. Default to US; switch on explicit user confirmation or 401. - Auth:
Authorization: Bearer $POSTHOG_PERSONAL_API_KEY(key formatphx_*). - Most endpoints are project-scoped:
/api/projects/{project_id}/.... Get ids viaGET /api/projects/. Newer/api/environments/{id}/...routes coexist; preferprojects. - Personal API keys carry scopes (
query:read,feature_flag:read/write,insight:read/write,event:read,person:read/write,experiment:read/write, etc.). Wrong scope = silent 403 or filtered result. - Rate limits (team-wide): Query 2400/hr · Analytics 240/min + 1200/hr · Events 60/min + 300/hr · Flag local-eval 600/min · CRUD 480/min + 4800/hr.
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.

posthog is a skill published in the GitHub repository mnlt/teleport (8 stars, last pushed 5mo ago), licensed MIT. It adds 73 tokens to every session and 1,742 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

save-learning
Saves user instructions as persistent learnings for future sessions. Use when the user says 'remember this', 'always do X', 'from now on', 'never do Y', or gives any instruction they want persisted across sessions. Proactively suggest when the user states a preference, convention, or rule they clearly want followed in…

A method for handling difficult web tasks across search, page fetching, and a real browser. It covers sites that need login sessions, dynamic pages, anti-bot handling, or exploration before their structure is understood.

A skill for creating or improving reusable instructions for an agent. It covers capturing the intended workflow, writing a draft, testing it, and refining its trigger description.

Decide which files a task actually needs, record that as a reusable llm-context rule, verify it against the codebase - including the files your selection references but leaves out - and pack it for your own context, a chat, or a sub-agent you dispatch.
