Configuration

For operators who want to change how the screen behaves: this page tells you which file to edit for which wish, with one worked example per task. Every key and field is defined in the Configuration reference.

Which layer to change

Three layers, from a file edit to a pull request:

Layer	What lives there	How to change it
configuration	the per-component choices in telescreen.yaml (agent, args, instructions, allowlist, timeout, action map, publisher routing); identity and secrets in the env files; cadence	edit the files below; no rebuild
enrollment	which program plays each role: producer, speakwrite agent, actor	enroll your own unit in place of a shipped one; the Queue contract is the interface
the binary	the drawer names and record grammar, the keys, the double-key approval, the built-in publisher match rules (which URL goes to GitHub, Slack, Linear by default)	a pull request to this repo

Choosing an implementation is never a config key: you enroll a unit. The last row is deliberately fixed: the grammar is what makes every component replaceable, so it moves by PR, not per user.

One pane of glass

~/.config/telescreen.yaml holds the choices per component: the minitrue and speakwrite keys each carry the agent, its args template, an instructions file, the allowlist, and the timeout; speakwrite also carries the action map. telescreen install seeds the file and never overwrites your edits: a re-install only appends a component key you deleted. The env files stay for identity and secrets, and their agent keys work as the fallback layer when a field is unset in the YAML.

A complete file, every key in use:

minitrue:
  agent: codex                       # any agent CLI; claude is the default
  args: exec {prompt}                # its argv shape; {prompt} lands as one argument
  instructions: ~/notes/producer.md  # file content becomes the prompt
  timeout: 900                       # seconds before the run is killed
speakwrite:
  agent: claude                      # claude reads the installed skill, so no
  allowed_tools: mcp__github mcp__slack   # instructions field is needed here
  actions:                           # replaces the built-in action map entirely
    - url_prefix: https://github.com/acme/
      action: review
      guidance: professional register
    - source: slack
      action: slack-reply
thinkpol:
  publishers:                        # routing for the actor's publisher table
    - publisher: github-pr
      url_prefix: https://github.example.com/   # an enterprise host
    - publisher: exec                # a custom backend as a script
      url_prefix: https://forum.example.com/
      command: forum-post {url}      # draft on stdin, permalink on stdout

Every field is optional except action inside a rule; an absent field falls back to the env-file key, then the default. Field semantics: Configuration reference.

Add a rule to the action map

Edit ~/.config/telescreen.yaml under speakwrite.actions. A non-empty actions list replaces the built-ins entirely, so bring every rule you still want. The rule fields, the match order, and the built-in map are defined in the Configuration reference.

Example: two Slack workspaces, two registers.

speakwrite:
  actions:
    - url_prefix: https://acme.enterprise.slack.com/   # the work workspace
      action: slack-reply
      guidance: professional register
    - url_prefix: https://friends.slack.com/           # the personal workspace
      action: slack-reply
      guidance: casual register, first names
    - source: slack            # any other workspace
      action: slack-reply
    - source: github           # keep the built-in GitHub routing
      name_contains: -review-requested-
      action: review
    - source: github
      who_suffix: "[bot]"
      action: vet-findings
    - source: github
      action: pr-reply
    - source: linear
      action: linear-comment

Change the agent or the prompt

The agent binary and its instructions are telescreen.yaml fields: set agent and instructions under minitrue for the producer, under speakwrite for the speakwrite agent. instructions names a file whose content becomes the prompt. Use an absolute path when the binary is not on the unit's PATH, and carry your environment's MCP tool identifiers in allowed_tools. All fields, the env fallback keys, and defaults: Configuration reference. A CLI with different flags than claude also needs the args template; the worked example lives in Use another agent.

The prompts themselves are skills. telescreen install writes seeds under ~/.claude/skills/; the agents read the installed files at run time, so editing ~/.claude/skills/speakwrite/SKILL.md changes how drafts are written without touching Go. Re-installs keep your edits (--force restores the shipped versions).

New action verbs live in the same file: speakwrite drafts whatever the skill says a verb means, so a custom summarize action works as soon as your speakwrite skill defines it.

Route or add a publisher

Edit ~/.config/telescreen.yaml under thinkpol.publishers. Rules route by URL prefix to a named publisher, disable one, or define an exec backend; unmatched URLs fall back to the built-in matching. The fields and the routing order are defined in the Configuration reference.

Example: an enterprise GitHub, no Slack posting, a forum script.

thinkpol:
  publishers:
    - publisher: github-pr
      url_prefix: https://github.example.com/   # route the enterprise host
    - publisher: slack-thread
      enabled: false                             # never post to Slack
    - publisher: exec
      url_prefix: https://forum.example.com/
      command: forum-post {url}

The exec command runs without a shell, gets the record URL as one argument and the draft on stdin, and prints the permalink as its first stdout line. Any token the script needs goes in thinkpol.env, never in the YAML.

Set credentials

The actor's tokens live in ~/.config/thinkpol.env; chmod 600 it. The github-pr publisher uses your authenticated gh and needs no token there. Keys and failure behavior: Configuration reference.

Change the cadence

The producer cadence and the path units' trigger bounds are systemd settings: systemctl --user edit minitrue.timer, not a config file.
