What it does when it runs
Read from the skill and the 1 file bundled beside it. A skill’s own description is written to be selected by an agent, so it describes the job and not the dependencies.
- Keys and connectors you must supply
- API_KEY
- Hosts it reaches
- api.fathom.ai
- api.fireflies.ai
- Tool permissions it declares
- No

Or take the whole library
This repo ships a .claude-plugin manifest, so Claude Code can install all 7 skills at once. Plugin skills are invoked as /<plugin>:<skill>, so they never collide with your own.
/plugin marketplace add himanshusaleria/gtm-engine /plugin
The folder is the same in every client that implements the format — 46 of them — so if yours is not above, only the destination changes.
Before you install: this skill will not complete its job on a bare agent. It needs API_KEY, which you have to obtain separately.
The skill
Source on GitHub ↗Reproduced in full from himanshusaleria/gtm-engine/blob/df3d2814e760d2232f7845b901b3b5350e4d671c/skills/sync-calls/SKILL.md, which is licensed MIT (repository). 901 words, 26 headings.
/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 } } }"}'
If provider is otter, grain, or unknown:
Say: "Your provider ({provider}) doesn't have API sync. You can import transcripts manually:"
- Ask: "Paste a transcript, drop a file path, or type 'skip'"
- If they paste/provide a file, go to Step 4c for formatting and saving
- If skip, exit
Parse the response. Filter to only show calls created AFTER the last sync timestamp (from memory/call_sync.md). If --all flag, skip the filter and show all.
If --id flag, skip listing and go directly to Step 4 for that recording.
Step 3: Present Calls for Selection
Show the user a numbered list of new calls:
## New Calls Since Last Sync
| # | Date | Title / Participants | Recording ID |
|---|------|---------------------|--------------|
| 1 | 2025-03-10 | Acme Corp - Discovery | 12345678 |
| 2 | 2025-03-11 | Beta Inc - Follow-up | 12345679 |
Ask: "Which calls should I import? (all / numbers / skip)"
Step 4: Import Selected Calls
For each selected call:
4a: Fetch Summary
Fathom:
curl -s -H "X-Api-Key: $API_KEY" \
"https://api.fathom.ai/external/v1/recordings/{recording_id}/summary"
Fireflies:
Summary is included in the transcript response (use the summary field from the GraphQL query).
4b: Fetch Transcript
Fathom:
curl -s -H "X-Api-Key: $API_KEY" \
"https://api.fathom.ai/external/v1/recordings/{recording_id}/transcript"
Fireflies: Transcript sentences are included in the initial GraphQL response.
4c: Determine File Routing
Route the file based on call type:
- Customer/prospect calls ->
my-context/call-transcripts/ - Cohort/accountability calls -> only if
config.ritual.cohort.enabled, route to acohort/folder or skip
Use this naming convention: {company}_{date}_{topic}.md
- Company: lowercase, underscores for spaces
- Date: YYYYMMDD or monthDD format (e.g., mar10)
- Topic: brief descriptor (discovery, demo, followup, kickoff, poc_review)
Example: acme_corp_mar10_discovery.md
4d: Ask User to Confirm
Before writing, show:
- Proposed filename and path
- Call summary preview
- Ask: "Save this? (yes / rename / skip)"
If rename -> let user specify new filename.
4e: Write the File
Format the transcript file as:
# {Call Title}
**Date:** {date}
**Participants:** {list from API}
**Source:** {provider name}
## Summary
{Provider-generated summary}
## Key Points
{Extract key points from summary if available}
## Transcript
{Full transcript with speaker labels}
Step 5: Update Sync State
After all imports complete, update memory/call_sync.md:
# Call Sync State
- **Provider:** {provider}
- **Last synced:** {current ISO timestamp}
- **Last imported call date:** {date of most recent imported call}
- **Last imported recording_id:** {id}
## Import History
| Date | Recording ID | File | Company |
|------|-------------|------|---------|
| {date} | {id} | {filepath} | {company} |
Append new imports to the history table (don't overwrite previous entries).
Step 6: Offer Next Steps
After import, ask:
- "Want me to analyse any of these calls?" -> triggers
/analyse-call - "Want me to create follow-up tasks?" -> creates tasks in {config.linear.action_team}
Mode: --all
Show all calls from the API response, not just those after last sync. Useful for re-importing or finding older calls.
Mode: --id {recording_id}
Skip the listing step. Directly fetch summary + transcript for the given recording ID. Still confirm filename before saving.
Notes
- The API key is stored in
.envand referenced by the env var name in config - If the API returns an error, show the error and suggest checking the API key
- If
memory/call_sync.mddoesn't exist, treat all calls as new (first run) - Always confirm with the user before writing files — never auto-import without approval
- For providers without API support, the skill gracefully falls back to manual import
Files bundled with it
These load only when the skill asks for them, so they cost nothing until it runs.
