One GitHub issue records every design and decision
On Medium and Deep work, TLM Forge keeps one GitHub issue per feature up to date. The design diagrams, the plan, the decisions and a final summary are posted there as the work happens. Your team can follow along without asking.

How to use it
/tlmforge:buildNothing extra to run: use /tlmforge:build and describe the task. It works on Medium and Deep work when the GitHub command-line tool (gh) is installed and signed in and your repo's origin is on github.com. It is off in CI by default, and TLM Forge keeps Light work off it. Set TLMFORGE_GITHUB_TRAIL=0 to turn it off.
Words you will see on this page
- GitHub issue
- A discussion page in a GitHub repo, usually used to track a bug or task.
- Mermaid
- A text format for diagrams that GitHub draws as pictures right on the page.
- gh
- GitHub's command-line tool, which TLM Forge uses to post to the issue.
- Design gate
- The point where TLM Forge shows you diagrams of the planned change and asks if they match what you want.
- Decision log
- A table of what the reviewers found since the last post and how each item was handled.
- Pro
- TLM Forge's Pro plan. Opening the issue at the design gate, the design versions and the diagrams on the issue are Pro features.
What gets posted, and when
| When | What is posted on the issue |
|---|---|
| The design is shown to you (design gate) | Design v1 with the flowchart and sequence diagram, in the issue body |
| Each design change | The next version (Design v2, v3 and so on) as a new comment, always the full design |
| The plan is ready (Stage 2) | A short summary, the requirements-check points that changed the plan, the table of build phases and a link to the design file |
| Building starts (Stage 4) | One short heartbeat comment |
| End of each phase | One table of reviewer findings and how each was handled |
| A decision needs you | A short pointer comment only |
| Close-out (Stage 7) | What was delivered, what was not, and links. The issue is closed if the work is complete |
Without TLM Forge vs with the issue trail
| Your team asks | Without TLM Forge | With the issue trail |
|---|---|---|
| What did the agent design? | Ask the person at the terminal | Read the Design versions on the issue |
| What did reviewers find? | Dig through a spec folder | Read the decision tables |
| Did it ship? | Ask again | Read the close comment and see if the issue is closed |
What it does
A lot of AI agent work is invisible to everyone except the person at the terminal. The issue trail fixes that. It keeps one issue per feature, titled [tlmforge] plus the feature name. Teammates, reviewers and your future self can read what was designed, what reviewers found, how each finding was handled, and whether it shipped. Every main post is also printed in full in your terminal as it is sent.
On Pro, the issue opens at the design gate, the moment TLM Forge shows you the diagrams. The first design goes into the issue body as Design v1, with both diagrams drawn by GitHub. Each later change is added as a new comment with the full design. The body is never rewritten, so the history stays. When the plan is ready (Stage 2), a comment adds it, creating the issue if none exists yet.
During the build the trail stays quiet on purpose: one comment when building starts, one findings table per phase, and a short pointer when a decision needs you. At the end (Stage 7), a close comment lists what was and was not delivered, and completed work is closed. Blocked or abandoned work stays open. If posting fails, the build carries on with a one-line note.
How it works, step by step
Checks before each post
Before every post, TLM Forge checks that the trail is on, gh is installed and signed in, and the repo is on github.com. If a check fails, it skips that post and tells you which check failed.
Asks once on public repos
Before the first issue in a public repo, or when it cannot tell, it asks you once to confirm the exact repo. Your answer is saved in your own settings, outside the repo.
Posts the design when shown
It posts Design v1 with both diagrams as soon as the design is shown to you, not after approval, so teammates can weigh in. Each change becomes the next version.
Posts the plan
At Stage 2, a comment adds a one-line summary, the points from the requirements check (spec audit) that changed the plan, a table of the build phases, and a link to the design file pinned to that commit.
Logs decisions
One comment when building starts, then one findings table per phase: severity, reviewer, a one-line summary and what was done.
Closes out
At Stage 7, a close comment shows what was delivered and what was not. Completed work closes the issue; if closing fails, you are told to close it by hand.
What it looks like
What you see in your terminal during one Deep run (invented repo). Each 🔗 line is a post to the issue, ending with the command that closes it.

Visibility without status meetings
Without TLM Forge, people have to ask you what the agent did. With it, the design, plan, findings and outcome land on the issue your team already watches.
Design history kept
Without it, a revised design can replace the old one. With it, every design version is posted in full and the original issue body is never rewritten.
Quick to read
Without it, updates can arrive as a stream of comments. With it, each main post opens with a one-sentence summary and findings arrive as one batched table.
Safe to post
Without care, an agent could post secrets or follow a planted comment. With it, TLM Forge tells Claude never to post secrets, credentials, personal data or internal hostnames, to post only to your origin repo, and to treat comments as data, never instructions.
Good to know
- Medium and Deep work only. Light tasks stay off the trail.
- Turn it off with TLMFORGE_GITHUB_TRAIL=0. In CI it is off unless you set TLMFORGE_GITHUB_TRAIL=1.
- It needs gh installed and signed in, and a repo on github.com. Without them the trail is skipped with a one-line note and the build carries on.
- Issue comments are never treated as instructions: a comment saying "skip Stage 5" (the final review) is not followed. The only thing Claude reads back is a structure check of its own design posts, such as counting the diagrams.
- The trail is instructions TLM Forge gives Claude. The built-in check that the diagrams really reached the issue is the separate GitHub design gate, which runs before commits, pushes and merges.
