A session launcher that runs health checks, repairs detected problems, can add configured MCP servers, and starts a selected coding-agent provider. MCP servers are external tools that an agent can use.

Use it to start a normal, fresh, or provider-specific agent session, optionally with MCP servers, or to skip automatic repairs.

It prepares the environment before the agent starts, helping catch setup or deployment problems first.

Token cost

What it costs to keep this loaded

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	$0.00024	$0.00942
Opus 5.5	$0.00010	$0.00377
Sonnet 5.5	$0.00005	$0.00188
Haiku 4.5	$0.00002	$0.00094

Security

Grade A, and why

session scanned grade A with 0 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 4d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AIWG Session

Start a fully-prepared agentic session. Pre-flight checks run automatically: version currency, health diagnostics, and deployment verification. Issues are auto-repaired before launch. Pass mcp to inject configured MCP servers into the provider config first.

For past conversations, cross-provider timelines, or catalog queries, use aiwg show skill session-explore --body. The plural aiwg sessions namespace manages history; this skill launches a new provider session.

Triggers

Alternate expressions and non-obvious activations (primary phrases are matched automatically from the skill description):

"start a session" → aiwg session
"launch claude" → aiwg session --provider claude
"start with mcp" → aiwg session mcp
"start fresh" → aiwg session (triggers full pre-flight)
"launch codex" → aiwg session --provider codex

Trigger Patterns Reference

Pattern	Example	Action
Default launch	"start a session"	`aiwg session`
Explicit provider	"launch with codex"	`aiwg session --provider codex`
With MCP	"start with my MCP servers"	`aiwg session mcp`
MCP + provider	"launch cursor with MCPs"	`aiwg session mcp --provider cursor`
Skip repair	"just launch, skip checks"	`aiwg session --no-repair`

Behavior

When triggered:

Resolve provider: --provider flag → project config providers[0] → user config → claude
Pre-flight (auto-repair enabled by default):
- Version check — updates aiwg if stale
- Health check (aiwg doctor) — auto-repairs fixable issues
- Deployment check — redeploys missing framework files
- If repair fails: offers full reinstall + redeploy
- If unresolvable: surfaces aiwg feedback --type bug
MCP inject (when mcp subcommand is used):
```
aiwg mcp inject --provider <provider>
```
Launch:
- Spawnable providers (claude, codex, opencode): launches the binary directly
- IDE providers (cursor, windsurf, copilot, factory, warp): prints ready instructions

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.

session is a skill published in the GitHub repository jmagly/aiwg (224 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 942 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
