Completes the project-local skills epic's remaining skill items (#48974,
#48975) on top of the discovery/trust work in #88566.
Quarantine (#48974): trust is a repo-level decision made once, but repo
skill content changes with every pull — the hub install path scans, a
checkout didn't. Every project SKILL.md dir now runs through the same
skills_guard scanner as hub installs (content-hash cached under
~/.hermes/cache/project_skill_scans/, never inside the repo). Verdict
'dangerous' quarantines the skill: excluded from the index, skills_list,
and slash commands via the single iteration chokepoint
iter_project_skill_files(), and skill_view refuses by name with an
explanatory error. Scanner failure fails closed. Verified against a real
injection fixture (6 findings: prompt_injection_ignore, deception_hide,
invisible_unicode, credential exfil patterns).
Non-interactive inheritance (#48975): find_project_root() now resolves
from TERMINAL_CWD (the per-surface workdir cron jobs and the terminal
tool already use) before falling back to process cwd. Cron/API/ACP
surfaces inherit a prior interactive trust decision by project identity:
job workdir inside a trusted repo => project skills load; untrusted or
no workdir => nothing loads; no surface ever prompts.
Tests: +10 cases in tests/agent/test_project_skills.py (real malicious
fixture, fail-closed, rescan-on-change, cache location, TERMINAL_CWD
inheritance matrix). Docs: quarantine + non-interactive sections in
skills.md.
Sessions started inside a git checkout now source skills from
<root>/.hermes/skills/ and <root>/.agents/skills/ (the cross-tool
convention shared with other agent harnesses) as the highest-precedence
skill tier: project > local > external_dirs.
Loading is trust-gated per repo (skills.trusted_project_dirs, managed by
'hermes skills trust'/'untrust') because skills are executable procedure
documents — auto-sourcing them from any cloned repo is a prompt-injection
vector. Untrusted repos with skills get a one-line banner notice instead.
- agent/skill_utils.py: find_project_root, get_project_skills_dirs,
get_untrusted_project_skills_root, get_scan_ordered_skills_dirs;
project dirs join the curator read-only ownership boundary
- agent/prompt_builder.py: project tier scanned first, entries tagged
[project], same-named local entries shadowed; cache key extended
- tools/skills_tool.py: skills_list scans project dirs first (first-wins);
skill_view resolves cross-tier collisions in favor of the project tier
(same-tier ambiguity still refuses); security warning recognizes the tier
- agent/skill_commands.py + hermes_cli/commands.py: /skill-name slash
commands and gateway slash menus include project skills
- tools/credential_files.py: project dirs mounted into remote backends
- cli.py: banner notice (loaded count / trust hint)
- hermes_cli/main.py + subcommands/skills.py: hermes skills trust/untrust
- config: skills.project_discovery (default on), skills.trusted_project_dirs
- docs: Project-Local Skills section in skills.md
- tests: tests/agent/test_project_skills.py (18 cases)
Session cwd is fixed at agent build time, so the resolved tier is stable
for the conversation and the system prompt stays byte-stable (cache-safe).
