- Calls rg
What it does
Before changing reusable assets, the agent reads AGENTS.md, skills/.env and the relevant existing files, then classifies the change. SKILL.md holds routing and short operating rules, references hold the detailed workflows, cases are executable test-plan skeletons, suites are groups of case ids, fixtures.json carries fixture readiness metadata, and each troubleshooting file covers one reusable failure mode. Run evidence under reports is output, not something to commit. The agent searches existing assets with rg and the bin/lbs list commands first, puts detail in a single canonical place, links to it and runs the checks listed in AGENTS.md.
A set of entropy rules keeps the repository small: extend an existing entry when the root cause matches, keep cases to setup, action, evidence and checks, keep suites to a title, intent, tags and ordered case ids, and keep fixture manifests factual without absolute paths. Ports, browser profile paths, secrets, tokens and provider keys are never hardcoded. bin/lbs index --check verifies the committed index without writing it, and references/curation-workflow.md covers periodic audits.
When your agent uses it
- Adding or editing a LangBot skill, reference, case or troubleshooting entry
- Deciding where a new piece of detail belongs before creating a file
- Running a periodic audit of the skills repository for duplication
Example prompts
- “Add a troubleshooting entry for the webhook timeout, but check first whether one already covers it.”
- “Audit the langbot-skills repository for duplicated cases and stale references.”
- “Add a new case for the Telegram adapter and put it in the right suite.”
- “Check whether the committed index is current.”
Requirements
- A checkout of the langbot-skills repository with its bin/lbs tool
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Read AGENTS.md, skills/.env, and the relevant existing skill files.
- Classify the change
- Search existing assets before adding new files
- Put detail in one canonical place and link to it from cases or routing bullets.
- Run the checks in AGENTS.md after edits.
What it can do on your machine
Read from SKILL.md and the folder at commit 0b5b4cc. 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:
rg
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
LangBot Skills Maintenance loads about 603 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 270 words of instructions outside code blocks.
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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

1. Read `AGENTS.md`, `skills/.env`, and the relevant existing skill files.
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.

LangBot Skills Maintenance
Use this skill before changing reusable assets in this repository.
Workflow
- Read
AGENTS.md,skills/.env, and the relevant existing skill files. - Classify the change:
SKILL.mdfor routing and concise operating rules.references/*.mdfor canonical detailed workflows.cases/*.yamlfor executable test-plan skeletons.suites/*.yamlfor reusable groups of case ids.fixtures/fixtures.jsonfor deterministic fixture readiness metadata.reports/evidence/<run-id>/automation-result.jsonas automation output andreports/evidence/<run-id>/result.jsonas final judgment output; neither is a catalog asset to commit.troubleshooting/*.yamlfor one reusable failure mode.
- Search existing assets before adding new files:
rg "<feature|error|case id>" skillsbin/lbs case listbin/lbs suite listbin/lbs fixture list
- Put detail in one canonical place and link to it from cases or routing bullets.
- Run the checks in
AGENTS.mdafter edits.
Entropy Rules
- Prefer extending an existing reference or troubleshooting entry when the root cause is the same.
- Keep cases short: setup, action, evidence, pass/fail checks. Do not paste long prompts or debug transcripts when a reference exists.
- Put machine-checkable inputs in
env,automation_env, or fixtures; put operator-confirmed assumptions inpreconditionssotest plancan surfacemanual_check. - Keep suites short: title, intent, tags, and ordered case ids. Do not duplicate case steps inside a suite.
- Keep fixture manifests factual: id, title, path, kind, and related case ids. Do not encode environment-specific absolute paths.
- Keep troubleshooting entries narrow: symptoms, patterns, likely causes, fixes, related assets.
- Do not hardcode local ports, browser profile paths, secrets, tokens, or provider keys.
- Use
bin/lbs index --checkto verify the committed index is current without writing it; runbin/lbs indexwhen the index needs regeneration.
For periodic repository audits, read references/curation-workflow.md.
