What it does

Replay Session is an agent skill from fullsend-ai/fullsend. Use when the user wants to replay a Claude Code session from a GitHub Actions artifact link. Downloads the artifact, finds JSONL files, generates an interactive HTML replay with claude-replay, and serves it locally.

Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires claude-replay (npm install -g claude-replay) and gh CLI authenticated with access to the target repository

It sits in DevOps & Cloud, covering CI/CD and HTML artifacts. It works with GitHub Actions. The repository describes itself as: On the path to fully autonomous agentic engineering. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 6c6be1e. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- gh

Network
Hosts in commands or code, which the agent is likely to contact:

Credentials
Names no API keys, tokens, secrets or passwords.

From compatibility in the SKILL.md frontmatter.

Context cost

Replay Session loads about 884 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~58
When it runs · the whole SKILL.md, loaded when a task matches: ~884

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

compatibility: Requires claude-replay (npm install -g claude-replay) and gh CLI authenticated with access to the target repository

Replay Session from GitHub Actions Artifact

Generate an interactive HTML replay from a JSONL transcript stored in a GitHub Actions artifact.

Prerequisites

claude-replay installed globally (npm install -g claude-replay)
gh CLI authenticated with access to the target repository

Workflow

1. Get the artifact

The user provides a GitHub Actions run URL. Extract the owner, repo, and run ID from it.

URL formats to expect:

https://github.com/OWNER/REPO/actions/runs/RUN_ID
https://github.com/OWNER/REPO/actions/runs/RUN_ID/attempts/N
https://github.com/OWNER/REPO/actions/runs/RUN_ID/artifacts/ARTIFACT_ID
Or the user may just give a run ID and repo name separately

2. Ask clarifying questions

Before downloading, interactively ask the user:

Which artifact? Run gh run view <run-id> -R OWNER/REPO to list the artifacts available in that run. If there are multiple artifacts, ask which one to use.
Which JSONL? After downloading, list the JSONL files grouped by iteration with their sizes. Each artifact represents a single agent — all JSONL files inside belong to that agent across its iterations. Default to replaying all files. Only ask the user to narrow down if they want a specific iteration or subset.
Replay options? Ask if they want any special options (turn range, theme, hide thinking blocks, redact strings). Defaults are fine for most cases — don't over-ask.

3. Download the artifact

bash

TMPDIR=$(mktemp -d /tmp/replay-XXXXXX)
gh run download <run-id> -R OWNER/REPO -n "<artifact-name>" -D "$TMPDIR/artifact"

4. Find the JSONL file(s)

The downloaded artifact represents a single agent run. Its top-level directory (e.g., agent-code-2446-1776439672/) is the agent identifier. All JSONL files inside — across all iteration-N/ subdirectories — belong to this agent. There is no need to ask the user which agent to replay.

bash

find "$TMPDIR/artifact" -name "*.jsonl" -type f

List the files to the user grouped by iteration, with sizes, so they can choose "all" (default) or a specific subset.

Show full SKILL.md (121 more words)Show less

5. Generate and serve the replay

bash

claude-replay <path-to-jsonl> --no-compress -o "$TMPDIR/replay.html" [extra options]
claude-replay <path-to-jsonl> --no-compress --serve --port 7331

Always use --no-compress — compressed replays fail to render in some browsers.

If port 7331 is busy, try 7332, 7333, etc.

Present the URL to the user: http://127.0.0.1:<port>

6. Multiple JSONL files

If the user wants to replay multiple files (e.g., main + subagents), chain them:

bash

claude-replay file1.jsonl file2.jsonl file3.jsonl -o "$TMPDIR/replay.html"

Notes

Always use /tmp for downloaded artifacts and generated HTML — never pollute the working directory.
The --serve flag works even though the process appears to exit immediately in the background. The server stays up — don't retry or switch to a different HTTP server.
Kill the previous server's port before starting a new one: kill $(lsof -ti:<port>) 2>/dev/null
Remind the user that the server will stop when the Claude Code session ends.
