What it does
Tessl Skill Linting is an agent skill from Devolutions/devolutions-gateway. Review, lint, create, edit, refine, optimize, compress, or validate any agent skill in this repository, including any SKILL.md. Use this skill whenever a user asks to author or change a skill, improve its instructions or trigger coverage, assess skill quality, or reduce its context usage, even when Tessl is not mentioned. Keep skills small and split distinct workflows into focused micro-skills when that reduces context and trigger overlap. Do not use it for ordinary application code, documentation, or workflow…
Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts.
It sits in Development, covering Linting and formatting and Technical documentation. The repository describes itself as: A blazing fast relay server adaptable to different protocols and desired levels of traffic inspection. The licence is Apache-2.0.
When your agent uses it
- A user asks to author
- Improve its instructions
- Trigger coverage
- Assess skill quality
Example prompts
- “/tessl-skill-linting”
Requirements
- PowerShell
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Identify the relevant skill directories under .agents/skills.
- Inspect the frontmatter and instructions for valid structure, clear trigger conditions, focused scope, missing prerequisites, accurate and…
- Run local structural validation for every relevant skill
- Make only clearly justified edits inside the relevant skill and directly related local eval artifacts.
- Perform a deliberate compression pass.
- Re-run the local lint helper after edits and inspect the final diff.
What it can do on your machine
Read from SKILL.md and the folder at commit 62de985. 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
Ships 1 file in scripts/ (PowerShell), which the agent can run.
Shell commands in SKILL.md call:
pwsh
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
Tessl Skill Linting loads about 740 tokens when it runs. Until then it costs about 143 tokens; SKILL.md has 301 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 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); the scripts in this folder are not scanned.
SKILL.md
The full file from Devolutions/devolutions-gateway at commit 62de985, republished under its Apache-2.0 licence (© Devolutions). 301 words, ~740 tokens.

- Review, lint, create, edit, refine, optimize, compress, or validate any agent skill in this repository, including any SKILL.md. Use this skill whenever a user asks to author or change a skill, improve its instructions or trigger coverage, assess skill quality, or reduce its context usage, even when Tessl is not mentioned. Keep skills small and split distinct workflows into focused micro-skills when that reduces context and trigger overlap. Do not use it for ordinary application code, documentation, or workflow changes that are not agent skills.
Tessl Skill Linting
Keep repository-local agent skills correct, focused, and inexpensive to load.
Workflow
Identify the relevant skill directories under
.agents/skills. For an existing skill, read itsSKILL.mdbefore editing and preserve its intended behavior and scope. For a new skill, inspect neighboring skills for conventions, then create the target directory and initialSKILL.mdfrom the requested scope.Inspect the frontmatter and instructions for valid structure, clear trigger conditions, focused scope, missing prerequisites, accurate and safe tooling steps, ambiguity, brittleness, redundancy, and likely failure cases.
Run local structural validation for every relevant skill:
powershell pwsh <this-skill-directory>/scripts/Test-TesslSkill.ps1 -SkillDirectory <skill-directory>The helper stages the skill in a temporary directory, creates Tessl's required local metadata there, runs
tessl skill lint <temporary-skill-directory>, and removes the staging directory. Treat lint findings as input to fix when appropriate. Tessl lint validates structure, not whether the workflow is semantically complete.Make only clearly justified edits inside the relevant skill and directly related local eval artifacts. Do not change application code, unrelated skills, or repository configuration.
Perform a deliberate compression pass. Remove filler, repetition, ceremonial headings, generic advice, redundant rules, needless examples, and details better suited to a progressive-disclosure reference. Prefer concise imperative language. Keep the initial
SKILL.mdminimal; add a reference only when specialized material is substantial and needed conditionally. Prefer focused micro-skills over one broad skill when distinct workflows can trigger or load independently.Re-run the local lint helper after edits and inspect the final diff.
Report
State:
- Tessl lint findings and their resolution.
- Meaningful edits and the behavior they preserve or improve.
- Two or three recommended future local test prompts that exercise triggering and instructions.
Use Tessl only for temporary local import and structural linting.
Cloud features, including tessl skill review, managed evals, scenarios, project creation or linking, publishing, and credentials, are out of scope.
