What is Tessl?
Tessl is an agent enablement platform that manages the context, skills, and automated workflows developers provide to coding agents. It inventories existing instructions across connected repositories and runs evaluations on changes before they ship. A free tier with 1,000 monthly credits is available without a credit card.
What are the features of Tessl?
- Skill registryProvides a searchable index of agent instructions across an organization and private workspaces to prevent duplicate skill creation.
- Context activation trackingShows which skills are installed versus actively running in projects, and supports before-and-after evaluations on every change.
- Security scanningRuns STRIDE- and OWASP-style checks on pull requests and scheduled full-repository audits, scoring skills before installation.
- Automated loopsExecutes defined standards as scheduled tasks such as code review, documentation maintenance, test fixing, or incident post-mortems.
- Agent cost benchmarkingMeasures what a task costs to run in turns and tokens rather than relying solely on provider rate cards.
- Model switchingAllows changing providers via configuration and evaluating model and harness combinations against custom tasks.
What are the use cases of Tessl?
- Enterprise AI adoptionCisco uses Tessl to help tens of thousands of engineers shift from prompting to context engineering within an automated pipeline.
- Preventing duplicate instructionsTeams inventory existing skills across connected repositories to avoid spending time and tokens recreating solved problems.
- Catching skill regressionsDevelopers run evaluations on updated skills to ensure new versions do not silently degrade performance before deployment.
