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 | $0.00000 | $0.01629 |
| Opus 5.5 | $0.00000 | $0.00652 |
| Sonnet 5.5 | $0.00000 | $0.00326 |
| Haiku 4.5 | $0.00000 | $0.00163 |
Grade A, and why
sync-calls 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.

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 — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/sync-calls — Import Call Recordings
Fetch recent call recordings from your configured call recording provider, import transcripts, and save them as structured markdown files.
Usage
/sync-calls— Fetch new calls since last sync/sync-calls --all— Show all recent calls (ignore last-sync marker)/sync-calls --id {recording_id}— Import a specific recording by ID
Prerequisites
config/config.yamlwithintegrations.call_recording.providerset (e.g.,fathom,fireflies,otter,grain).envfile with the API key (env var name fromconfig.integrations.call_recording.api_key_env)
Supported Providers
| Provider | API Base | Auth Header |
|---|---|---|
fathom |
https://api.fathom.ai/external/v1 |
X-Api-Key |
fireflies |
https://api.fireflies.ai/graphql |
Authorization: Bearer |
otter |
Manual import (no API) | — |
grain |
Manual import (no API) | — |
For providers without an API (otter, grain, etc.), the skill prompts the user to paste or drop a transcript file instead.
Instructions
Step 1: Load Config and State
Read in parallel:
config/config.yaml->integrations.call_recordingsectionmemory/call_sync.md(if exists) -> last sync timestamp and last imported recording ID
Extract:
provider— which call recording tool (fathom, fireflies, otter, grain)api_key_env— name of the env var holding the API keyapi_base— API base URL (use default for known providers)
If call_recording.provider is not set or call_recording.enabled is false, tell the user: "No call recording provider configured. Run /setup to set one up, or add transcripts manually to my-context/call-transcripts/."
Step 2: Fetch Recent Calls
If provider is fathom:
curl -s -H "X-Api-Key: $API_KEY" \
"https://api.fathom.ai/external/v1/meetings"
If provider is fireflies:
curl -s -X POST "https://api.fireflies.ai/graphql" \
-H "Authorization: Bearer $API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "{ transcripts { id title date duration organizer_email participants sentences { speaker_name text } } }"}'
What ships with it
1 file 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.

sync-calls is a skill published in the GitHub repository himanshusaleria/gtm-engine (20 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,629 tokens. 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 2026-08-30.
